Last year, NVIDIA introduced its cuLitho software library, which promises to speed up photomask development by up to 40 times. Today, NVIDIA announced a partnership with TSMC and Synopsys to implement its computational lithography platform for production use, and use the company's next-generation Blackwell GPUs for AI and HPC applications.

The development of photomasks is a crucial step for every chip ever made, and NVIDIA's cuLitho platform, enhanced with new generative AI algorithms, significantly speeds up this process. NVIDIA says computational lithography consumes tens of billions of hours per year on CPUs. By leveraging GPU-accelerated computational lithography, cuLitho substantially improves over traditional CPU-based methods. For example, 350 NVIDIA H100 systems can now replace 40,000 CPU systems, resulting in faster production times, lower costs, and reduced space and power requirements.

NVIDIA claims its new generative AI algorithms provide an additional 2x speedup on the already accelerated processes enabled through cuLitho. This enhancement is particularly beneficial for the optical proximity correction (OPC) process, allowing the creation of near-perfect inverse masks to account for light diffraction.

TSMC says that integrating cuLitho into its workflow has resulted in a 45x speedup of curvilinear flows and an almost 60x improvement in Manhattan-style flows. Curvilinear flows involve mask shapes represented by curves, while Manhattan mask shapes are restricted to horizontal or vertical orientations.

Synopsys, a leading developer of electronic design automation (EDA), says that its Proteus mask synthesis software running on the NVIDIA cuLitho software library has accelerated computational workloads compared to current CPU-based methods. This acceleration is crucial for enabling angstrom-level scaling and reducing turnaround time in chip manufacturing.

The collaboration between NVIDIA, TSMC, and Synopsys represents a significant advancement in semiconductor manufacturing in general and cuLitho adoption in particular. By leveraging accelerated computing and generative AI, the partners are pushing semiconductor scaling possibilities and opening new innovation opportunities in chip designs.

NVIDIA Blackwell Architecture and B200/B100 Accelerators Announced: Going Bigger With Smaller Data Ryan Smith Already solidly in the driver’s seat of the generative AI accelerator market at this time, NVIDIA has long made it clear that the company isn’t about to slow down and check out the view. Instead, NVIDIA intends to continue iterating along its multi-generational product roadmap for GPUs and accelerators, to leverage its early advantage and stay ahead of its ever-growing coterie of competitors in the accelerator market. So while NVIDIA’s ridiculously popular H100/H200/GH200 series of accelerators are already the hottest ticket in Silicon Valley, it’s already time to talk about the next generation accelerator architecture to feed NVIDIA’s AI ambitions: Blackwell.

The NVIDIA GTC 2024 Keynote Live Blog (Starts at 1:00pm PT/20:00 UTC) Ryan Smith & Gavin Bonshor We're here in sunny San Jose California for the return of an event that's been a long-time coming: NVIDIA's in-person GTC. The Spring 2024 event, NVIDIA's marquee event for the year, promises to be a big one for NVIDIA, as the company is due to deliver updates on its all-important datacenter accelerator products – the successor to the GH100 GPU and its Hopper architecture – along with NVIDIA's other professional/enterprise hardware, networking gear, and, of course, a slew of software stack updates.

In the 5 years since NVIDIA was last able to hold a Spring GTC in person, a great deal has changed for the company. They're now the third biggest company in the world, thanks to explosive sales growth (and even further growth expectations) due in large part to the combination of GPT-3/4 and other transformer models, and NVIDIA's transformer-optimized H100 accelerator. As a result, NVIDIA is riding high in Silicon Valley, but to keep doing so they also will need to deliver the next big thing to push the envelope on performance, and keep a number of hungry competitors off their turf.

Headlining today's keynote is, of course, NVIDIA CEO Jensen Huang, whose kick-off address has finally outgrown the San Jose Convention Center. As a result, Huang is filling up the local SAP Center arena instead. Suffice it to say, it's a bigger venue for a bigger audience for a [i]much[/i] bigger company.

So come join the AnandTech crew for our live blog coverage of NVIDIA's biggest enterprise keynote in years. The presentation kicks off at 1pm Pacific, 4pm Eastern, 20:00 UTC.

StarTech Unveils 15-in-1 Thunderbolt 4/USB4 Dock with Quad Display Support Anton Shilov

StarTech.com has introduced its latest Thunderbolt 4/USB4 docking station, which has a plethora of ports and supports four display outputs. This makes it suitable for 4Kp60 quad-monitor setups often used for professional applications. The Thunderbolt 4 Quad Display Docking Station can also deliver up to 98W of power to the host, which is enough to feed a high-end laptop, such as Apple's MacBook Pro 16.

StarTech's 15-in-1 docking (132N-TB4USB4DOCK) has pretty much everything that one comes to expect from a dock engineered explicitly for demanding professionals, such as those involved in photography, content creation, video production, and computer-aided design. The unit comes with one Thunderbolt 4/USB 4 port with a 98W power delivery capability to connect to the host, a 2.5 GbE adapter, six USB Type-A ports (three supporting 10 Gbps, two supporting 5 Gbps, and one being USB 2.0 for up to 7.5W charging), one USB Type-C connector (at 10 Gbps), four display outputs (two DP 1.4, two HDMI 2.1), an SD Card reader with UHS-II, a microSD card reader with UHS-II, and a 3.5-mm audio jack. 

The dock's main selling feature is, its support for up to four displays. Of course, this is a valuable capability, but it has a couple of catches. The device can support four 4Kp60 displays when connected to a laptop featuring Intel's 12th or 14th Generation Core processor using a Thunderbolt 4 or USB 4 connector and with DSC enabled. With AMD Ryzen 6000 and Intel's 11th Gen Core-based systems, only three 4Kp60 displays are supported. Meanwhile, with MacBooks, users must get on with two 5Kp60 or one 6Kp60 display. The good news is that the Thunderbolt 4 Quad Display Docking Station requires no drivers and works seamlessly with MacOS, Windows, and ChromeOS.

The docking station has a 180W power supply, so it can simultaneously charge a laptop and power on all the remaining ports.

Thunderbolt 4 and USB 4 docks with rich capabilities are not cheap as they have to pack loads of quite expensive controllers, and StarTech's 15-in-1 docking station is no exception, as it costs $330.99

The StarTech.com Thunderbolt 4 Quad Display Docking Station is available for purchase directly from the company and through various IT resellers and distributors such as CDW, Amazon, Ingram Micro, TD SYNNEX, and D&H.

Qualcomm Announces Snapdragon 8s Gen 3: A Cheaper Chip For Premium Phones Ryan Smith

With the launch of their flagship Snapdragon 8 SoC firmly behind them now, Qualcomm this morning is turning their collective head towards the premium market with the launch of another new Snapdragon 8 family SoC, the Snapdragon 8s Gen 3. The first of Qualcomm’s ‘s’-subseries of down-market parts to be released under the Snapdragon 8 banner, the Snapdragon 8s Gen 3 (8sG3) is intended to be a bridge part between the last-gen flagship 8 Gen 2 and current-gen flagship 8 Gen 3, offering a not-quite-flagship experience at a lower price point than Qualcomm’s top SoC. The new SoC is set to be available globally, with the first phones announced this month, though as is often the case for Qualcomm’s “premium” market SoCs, it looks like only Chinese handset OEMs will be picking up the chip, at least initially.

Although Qualcomm prefers to draw comparisons to their current gen flagship Snapdragon 8 Gen 3, the Snapdragon 8s Gen 3 is by and large and enhanced version of the Snapdragon 8 Gen 2. Many of the hardware blocks of the 8G2 have been carried over to the new chip – either in whole or in terms of functionality – a process that is made very easy thanks to the fact that Qualcomm is building the chip on the same TSMC 4nm node as the 8G2 and 8G3. Compared to the 8G2 then, there are two key differentiators for the 8sG3: a newer CPU complex lifted from the 8G3, and official on-device generative AI support.

Starting with the CPU complex, Qualcomm is implementing Arm’s latest generation of Armv9 CPU cores here, meaning a mix of the Cortex-X4, Cortex-A720, and Cortex-A520. Relative to the flagship 8G3, the 8sG3 gives up one of its performance cores for another efficiency core, shifting the design from a 1/5/2 configuration to a 1/4/3 configuration – the same as the 8G2. The 8sG3 also loses some frequency headroom in the process, with the X4 prime core dropping from 3.3GHz to 3.0GHz, and the other CPU cores following similarly along.

Still, the 8sG3 should outperform the 8G2 in CPU tasks, which is the primary reason for replacing the CPU complex at all. Qualcomm is basically looking to offer an 8G2 with better CPU performance and energy efficiency, and using Arm’s latest CPU cores will be how they deliver on that.

Outside of the CPU complex, however, most of the rest of the functional blocks are either lifted from the 8G2, or are the same generation teams of features. This means the 8sG3’s integrated GPU offers hardware raytracing, for example, but not the global illumination support that was introduced for the flagship 8G3. The memory controller is also otherwise identical to the 8G2, with the SoC supporting a maximum of 24GB of LPDDDRX-8400.

The video recording and decoding capabilities of the 8sG3 are a distinct downgrade from the other Snapdragon 8 SoCs, however. Qualcomm has retained their trio of 18-bit Spectra ISPs – so the SoC can support up to 3 cameras – but all 8K support has been excised entirely. Instead, the 8sG3 can only record video at up to 4K, and even then only at 60fps, half the framerate of the 8G3/8G2. Slow-mo video capture has also been altered, as well; Qualcomm lists 1080p240 for this mode rather than 720p960. The higher resolution will no doubt be appreciated, but less so if this means it’s not possible to record above 240fps.

The lack of 8K video support also applies to the SoC’s video decode block, which can only decode videos up to 4K in resolution. Qualcomm has otherwise kept all of the underlying features of the video decode block at parity, however, so the 8sG3 gets support for AV1 decoding, along with Dolby Vision HDR.

Meanwhile, the DSP/NPU situation on the 8sG3 is a mixed bag. Officially, this SoC supports generative AI models (up to 10B parameters in size), something the 8G2 and its NPU were not capable of, and is otherwise only available on the 8G3. However, according to Qualcomm this is not the same generation of NPU IP as on the 8G3, and among other things it lacks support for speculative decoding (and I don’t see any mention of the newer NPU’s micro-tile inferencing improvements). So by all appearances, this is just the 8G2 NPU. Still, Qualcomm has at least rolled out some software/firmware updates to improve its functionality, giving it additional AI functionality right as exuberance for that is through the roof.

Finally, the comms side of the 8sG3 is essentially a slower version of the 8G2. Qualcomm is once again using their Snapdragon X70 integrated modem here, a 5G Release 17-generation design that offers 2x2 MIMO on mmWave, and 4x4 MIMO on sub-6G. Max upload speeds are unchanged, at 3.5Gbps, however max download speeds for the 8sG3 are 5Gbps, half that of the 8G2 (and 8G3). Paired with the X70 modem is Qualcomm’s FastConnect 7800 system, which offers Wi-Fi 7 support with 2x2 MIMO, as well as Bluetooth 5.4. The dual BT antenna feature from the other Snapdragon 8 chips has also made it over for this part.

Overall, the Snapdragon 8s Gen 3 is intended to occupy a very specific niche within Qualcomm’s SoC lineup, offering a cheaper alternative to their flagship SoC without giving up too many features. The marketing messaging behind the chip is made somewhat complicated by the fact that last year at this time Qualcomm launched the Snapdragon 7+ Gen 2 for the premium market, which at least partially overlaps what they’re trying to do with the 8sG3. None the less, Qualcomm insists there’s a market for chips between the Snapdragon 7 series and the flagship Snapdragon 8 SoC, and so here we are.

Absent another 7+ chip this year, it’s hard to see the 8sG3 as anything other than the 7+’s successor. Still, where the 7+ was a souped-up 7, the 8sG3 is clearly a down-market 8, so it has some significant hardware advantages, particularly when it comes to memory bandwidth. It may just be that Qualcomm aimed a bit too low for the premium market with the specs for the 7+, so this is an attempt to aim a bit higher.

In any case, expect to see the Snapdragon 8s Gen 3 picked up by many of the usual Chinese handset OEMs, including Honor, iQOO, realme, Redmi and Xiaomi. The first phones are expected to be announced this month.

BIOSTAR Debuts Barebones A620MS mATX Motherboard For Ryzen 7000 Processors Matthew Connatser

BIOSTAR has launched its AM5-based A620MS motherboard today, bringing a new low-end option for PC users on a budget. Though BIOSTAR has not disclosed what MSRP it the A620MS motherboard will carry, the specifications of the board make it clear that it targets the lowest-end segment of the market, though it makes use of the regular A620 chipset instead of the even less expensive A620A chipset.

The A620MS sports some features typical for mATX A620 boards (which make up the vast majority of current models): two DDR5 DIMM slots that support up to two 48GB sticks, an M.2 PCIe 4.0 slot for SSDs, four SATA III ports, and a PCIe Gen4 x16 slot. The motherboard also has four debug LEDs for diagnosing CPU, RAM, GPU, and booting errors.

Meanwhile the rear I/O features a one gigabit Ethernet port, four USB 3.2 ports, analog audio jacks, two USB 2.0 ports, an HDMI 1.4 port, and DisplayPort 1.2. Though there are some more fully-featured A620 motherboards available with more ports operating at a higher specification, but the rear I/O is more or less par for the course when it comes to A620.

However, there are other things about BIOSTAR’s A620MS that implies it will be quite low-end for an A620 motherboard. It has just eight total voltage regulator modules (VRMs), which appear to be in a 6+2 or 6+1+1 phase configuration. This isn’t as low-end as BIOSTAR could have gone (ASRock offers a 4+1+1 stage board), but it is still very sparing in VRM stages compared to most other A620 motherboards. These VRMs are also not covered by a heatsink, which is also typical for boards in this segment, as they're normally paired with equally chip 65W(ish) chips.

BIOSTAR doesn’t list any official CPU restrictions in either its press release or its specification sheet; instead, the company simply lists the motherboard as compatible with Ryzen 7000 and future Ryzen 8000 processors.

While the market for AM5 motherboards includes plenty of B650(E) and X670(E) models, there’s only a handful of A620 boards in total. On Newegg, there are 14 different motherboards available, and many only differ slightly in respect to things like form factor. The cheapest of these cost $75 to $100, and while BIOSTAR didn’t reveal what price we should expect of its A620MS board, given its specifications, we expect it will land in that same $75 to $100 region.

First DNA Data Storage Specification Released: First Step Towards Commercialization Anton Shilov

The DNA Data Storage Alliance introduced its inaugural specifications for DNA-based data storage this week. This specification outlines a method for encoding essential information within a DNA data archive, crucial for developing and commercializing an interoperable storage ecosystem.

DNA data storage uses short strings of deoxyribonucleic acid (DNA) called oligonucleotides (oligos) mixed together without a specific physical ordering scheme. This storage media lacks a dedicated controller and an organizational means to understand the proximity of one media subcomponent to another. DNA storage differs significantly from traditional media like tape, HDD, and SSD, which have fixed structures and controllers that can read and write data from the structured media. DNA's lack of physical structure requires a unique approach to initiate data retrieval, which brings its peculiarities regarding standardization. 

To address this, the SNIA DNA Archive Rosetta Stone (DARS) working group, part of the DNA Data Storage Alliance, has developed two specifications, Sector Zero and Sector One, to facilitate the process of starting a DNA archive. 

Sector Zero serves as the starting point, providing minimal details necessary for the archive reader to identify the entity responsible for synthesizing the DNA (e.g., Dell, Microsoft, Twist Bioscience) and the CODEC used for encoding Sector One (e.g., Super Codec, Hyper Codec, Jimbob's Codec). Sector Zero consists of 70 bases: the first 35 bases identify the vendor, and the second 35 bases identify the codec. The information in Sector Zero enables access and decoding of data stored in Sector One. The amount of data stored in SZ is small and fits into a single oligonucleotide.

Sector One expands on this by including a description of the contents, a file table, and parameters required for transferring data to a sequencer. This specification ensures that the main body of the archive is accessible and readable, paving the way for data retrieval. Sector One contains exactly 150 bases and will span multiple oligonucleotides. 

"A key goal of the DNA Data Storage Alliance is to set and publish specifications and standards that allow an interoperable DNA data storage ecosystem to grow," said Dave Landsman, of the DNA Data Storage Alliance Board of Directors. "With the publishing of the Alliance's first specifications, we take an important step in achieving that goal. Sector Zero and Sector One are now publicly available, allowing companies working in the space to adopt and implement."

The DNA Data Storage Alliance is led by Catalog Technologies, Inc., Quantum Corporation, Twist Bioscience Corporation, and Western Digital (though we are unsure whether Western Digital's NAND or HDD division is responsible for developing the specification). Meanwhile, numerous industry giants, including Microsoft, support the DNA Data Storage Alliance.

Asus Launches Low-Profile GeForce RTX 3050 6GB: A Tiny Graphics Card for All PCs Anton Shilov

Asus this week has become the latest PC video card manufacturer to announce a sub-75W video card based on NVIDIA's recently-released low-power GeForce RTX 3050 6GB design. And going one step further for small form factor PC owners, Asus has used NVIDIA's low-power GPU configuration to produce a half-height video card that can fit into low-profile systems.

As Asus puts it, the GeForce RTX 3050 LP BRK 6GB GDDR6 is a 'big productivity in a small package' and for a low-profile dual-slot graphics board, it indeed is. The unit has three display outputs, including a DVI-D, HDMI 2.1, and DisplayPort 1.4a with HDCP 2.3 support, which makes the graphics card s viable option both for a a dual-display desktop and a home theater PC (Nvidia's GA107 graphics processor supports all popular codecs except AV1). Furthermore, a DVI-D output enables the card to drive outdated displays, which even over half a decade after DVI-D was retired, still hang around as spare parts. Meanwhile, because the card only consumes around 70W, it does not require any auxiliary PCIe power connectors, which are at times not available in cheap systems from big PC makers.

Underlying this card is the aforementioned GeForce RTX 3050 6 GB, which uses the GA107 GPU with 2304 CUDA cores, and it comes with 6GB of GDDR6 memory connected to a narrower 96-bit memory bus (down from 128-bits for the full 8GB version. With a lower boost clock of 1470 MHz (1500 MHz in OC mode), the RTX 3050 6GB has reduced computing performance, delivering 6.77 FP32 TFLOPS versus 9.1 FP32 TFLOPS of the full-fledged RTX 3050.

As a result, the low-profile GeForce RTX 3050 6 GB is very much an entry-level card, though the low power requirements for such a card are also what make it special. This should be plenty for low-end gaming – beating out integrated GPUs – though suffice it to say, it's not going to compete with high-end, power-hungry cards either.

With its diminutive size, the Asus GeForce RTX 3050 LP BRK 6 GB GDDR6 looks to be a nice candidate for upgrading cheap systems from OEMs as well as fixing outdated PCs. What remains to be seen is how price competitive it is going to be. The graphics board already has one low-profile rival from MSI — which costs $185 — so Asus is not the only vendor competing here.

Asus Adds Support for 64GB Memory Modules to Intel 600/700 Motherboards Anton Shilov

Asus on Thursday said it has released new versions of UEFI BIOS for DDR5-supporting Intel 600/700-series motherboards that enable support for 64 GB DIMMs. As a result, Asus's latest platforms for Intel's 12th, 13th and 14th Generation Core processors with four slots for DIMM slots can now work with up to 256 GB of DDR5 memory, and motherboards with two DIMM slots can now support up to 128 GB of memory.

To gain support for 256 GB of DDR5 memory using 64 GB unbuffered DIMMs, one needs to download the latest version of UEFI BIOS for one of the Intel 600/700-series motherboards listed at the Asus website.

The list of Asus motherboards with an LGA1700 socket supporting 256 GB of DDR5 memory includes 75 boards based on a variety of Intel's 600 and 700-series chipsets, including Intel Z790, H770, B760, Z690, W680, and Q670. Though taking stock of Asus's larger motherboard offerings, this is still a bit shy of covering all of Asus's LGA1700 motherboards, which is nearly 200 models in total. So 64 GB DIMM support has only come to a fraction of their boards, at least thus far.

Otherwise, it is noteworthy that cutting-edge high-capacity DIMMs, such as 32 GB, 48GB, and 64 GB, are typically not available with the same blistering XMP clockspeeds as some of their lower-capacity counterparts, so equipping an Intel system with 256 GB of memory will come at a cost of peak memory bandwidth, on top of the typical DDR5 2 DIMM Per Channel (2DPC) frequency penalty. In fact, the fastest 48 GB modules currently offered by Corsair and G.Skill (which could be used to build systems with 192 GB of memory) top out at 6600 MT/s and 6800 MT/s, respectively. Meanwhile, for now, there are no Intel XMP 3.0-compatible 64 GB DDR5 modules from these two renowned makers.

Ultimately, the prime market for high-capacity UDIMMs at this time is going to be content creators, data scientists, and other workstation-light workloads that need a quarter-terabyte of RAM, and can justify the cost for the leading-edge DIMMs. Otherwise 16 GB and 32 GB DIMMs are likely to remain the sweet spot for the LGA1700 platform for the rest of its lifecycle.

Finally, it should be noted that Asus is also announcing (or rather, reiterating) support for 64 GB DIMMs on their AM5 motherboards. That said, this support is already baked into that platform and BIOSes, and unlike the Intel boards, a BIOS update is not needed.

Western Digital Launches PC SN5000S SSD: Low-Cost Meets High Performance Anton Shilov

Western Digital has introduced its new series of SSDs aimed at mainstream PCs, which combine high performance and low cost. The Western Digital PC SN5000S family of DRAM-less drives uses the company's 3D QLC NAND memory and an in-house-developed platform, so the SSDs promise to be relatively inexpensive. Meanwhile, their sequential read performance reaches 6,000 MB/s.

Western Digital's PC SN5000S drives are based on the company's latest in-house controller, which supports a PCIe 4.0 x4 host interface and BICS6 3D QLC NAND memory. The controller fully supports Western Digital's nCache 4.0 HybridSLC technology with endurance monitoring to ensure decent performance, RSA-3K and SHA-384 encryption, and TCG Opal 2.02 and Pyrite security capabilities.

On the capacity side, Western Digital's PC SN5000S drives will be available in 512 GB, 1 TB, and 2 TB configurations. As for performance, the 2TB PC SN5000S is rated for up to 6,000 MB/s sequential read speed, up to 5,600 MB/s sequential write speed, up to 750,000 random read IOPS, and up to 900,000 random write IOPS. The SSDs will be available in M.2-2230 and M.2-2280 form factors.

When it comes to endurance, Western Digital rates 2TB PC SN5000S at 600 terabytes to be written, 1TB version at 300TBW, and 512GB at 150TBW, which is significantly lower compared to entry-level SSDs with similar capacities (yet higher compared to WD Green-branded drives). 

While the performance of Western Digital's PC SN5000S hardly impresses our avid readers, who tend to look at the highest-end SSDs, 1TB and 2TB versions offer considerably higher performance than most entry-level drives on the market today. What disappoints is the relatively low endurance of Western Digital's new SSDs compared to entry-level drives from other makers.

Western Digital primarily markets its PC SN5000S solid-state drives for OEMs, where they succeed the company's SN740-series. For PC makers, the drives are fast enough, and perhaps more importantly, they support advanced encryption technologies as well as TCG Opal 2.02 and Pyrite security capabilities, which is crucial for desktops and laptops sold to various U.S. government agencies.

Intel Announces Core i9-14900KS: Raptor Lake-R Hits Up To 6.2 GHz Gavin Bonshor For the last several generations of desktop processors from Intel, the company has released a higher clocked, special-edition SKU under the KS moniker, which the company positions as their no-holds-barred performance part for that generation. For the 14th Generation Core family, Intel is keeping that tradition alive and well with the announcement of the Core i9-14900KS, which has been eagerly anticipated for months and finally unveiled for launch today. The Intel Core i9-14900KS is a special edition processor with P-Core turbo clock speeds of up to 6.2 GHz, which makes it the fastest desktop processor in the world... at least in terms of advertised frequencies it can achieve.

With their latest KS processor, Intel is looking to further push the envelope on what can be achieved with the company's now venerable Raptor Lake 8+16 silicon. With a further 200 MHz increase in clockspeeds at the top end, Intel is looking to deliver unrivaled desktop performance for enthusiasts. At the same time, as this is the 4th iteration of the "flagship" configuration of the RPL 8+16 die, Intel is looking to squeeze out one more speed boost from the Alder/Raptor family in order to go out on a high note before the entire architecture starts to ride off into the sunset later this year. To get there, Intel will need quite a bit of electricity, and $689 of your savings.

NETGEAR Introduces WBE750: First Insight-Manageable Wi-Fi 7 Access Point Targets Congested Deployments Ganesh T S

Wi-Fi 7 products have slowly started gaining market traction, particularly in the residential market (home consumer segment). The SMB / SME / enterprise market is traditionally a few quarters behind this, given the longer validation cycles. Earlier this year, Ubiquiti Networks introduced their first Wi-Fi 7 access point - the U7 Pro. Today, NETGEAR Business is launching the WBE750 Wi-Fi 7 Access Point (AP) in the Pro Wi-Fi lineup for businesses with heavy wireless Internet use.

The benefits of Wi-Fi 7 (802.11be) have been covered in multiple pieces earlier. The presence of a relatively interference-free 6 GHz band, wider channels (up to 320 MHz wide), and technical improvements to address interference and latency make the new standard an attractive upgrade for Wi-Fi users.

Unlike the Ubiquiti UniFi U7 Pro's entry-level focus (with 2x2 configurations in the 2.4 GHz, 5 GHz, and 6 GHz bands), the WBE750 opts for 4x4 configurations in each of the three bands. Correspondingly, the AP is able to support more concurrent connected clients (600 vs. 300), and obviously provide more bandwidth (18.4 Gbps vs. 9.2 Gbps theoretical). The pricing is also correspondingly higher ($700 vs. $190). The WBE750 also incorporates a NBASE-T (10 GbE / 5 GbE / 2.5 GbE / 1 GbE) RJ-45 uplink port with PoE++ support. Eight SSIDs are supported per channel.

Similar to other networking equipment vendors in this space, NETGEAR is also pushing for recurring subscription-based revenue with the product. A 1-year subscription to the single-pane cloud-based management interface (NETGEAR Insight) is included in the $700 purchase price.

NETGEAR Insight is particularly useful for professional installers who can manage multiple sites on the go, even from a mobile device.

The WBE750 joins a number of other Wi-Fi 6 / 6E APs in the Pro Wi-Fi line serving a wide range of deployment requirements. NETGEAR has been introducing multiple products in their Insight-manageable line over the last few quarters. As a result, they are able to offer a total network solution (gateways / routers / switches / APs) that can be managed from a single pane. As part of its Pro focus, NETGEAR is offering free site design services to installers along with expert technical support. NETGEAR's Pro WiFi Design Services (network design, product selection guide, troubleshooting, and training support) aims to be a key differentiation aspect compared to other similar offerings in the SMB / SME market.

The WBE750 is powered by a Qualcomm solution - the Waikiki Wi-Fi 7 chipset incorporated in the Networking Pro 1220 platform.

The new WBE750 AP is available for purchase today for $700.

Corsair Launches New XH405i Custom Water Cooling Kits And XG7 RTX 4080-Compatible Water Blocks Matthew Connatser

Corsair has launched its latest Hydro X series iCUE LINK XH405i RGB custom open-loop water cooling kits, replacing the older XH305i kits from 2020. The new kits feature Corsair’s latest XD5 RGB ELITE pump and reservoir, the XC7 RGB ELITE CPU waterblock, three QX120 RGB fans, and a 360mm radiator. The pump, waterblock, and fans all have the namesake iCUE LINK integration, which Corsair has been pushing throughout its entire recent generation of products.

The biggest hardware-related difference between XH405i kits and previous generation XH305i kits is undoubtedly the inclusion of iCUE LINK hardware, which Corsair recently debuted with its iCUE LINK H150i RGB AIO cooler. iCUE LINK allows individual Corsair cooling components within a system to be directly connected, primarily cutting down on cable clutter, but also offering the promise of more and finer-grained control over individual components via the iCUE LINK Hub at the center of a system. For instance, each individual iCUE LINK-compatible fan connected to the iCUE LINK hub can be set to its own speed, rather than either requiring each fan to be connected to its own fan header on the motherboard or setting a common speed for all fans via a multi-headed cable.

The XH405i is offered in two themes: stealth gray and white. Outside of cosmetics, the two variants are the same and come with a combined pump and reservoir, a CPU waterblock compatible with the AM5 and LGA 1700 sockets, three 120mm fans, a 360mm radiator, and a central iCUE LINK Hub. The kits also come with all the accessory components needed to build a custom loop: hardline tubing, a bending kit, fittings, and XL8 clear-colored coolant. These kinds of kits are usually geared towards newcomers to custom liquid cooling and users who need a brand-new loop but don’t want to spend much time scouring for individual components.

Separately, Corsair has also launched the iCUE LINK XG7 RGB GPU waterblock for GeForce RTX 4090 and 4080 Super graphics cards. As is typically the case for full-coverage GPU waterblocks, the XG7 has specific hardware compatibility requirements, and as a result Corsair is making four versions of the waterblock. The company is targetting ASUS’s ROG STRIX and TUF cards, as well as MSI’s SUPRIM and GAMING TRIO lineups, offering RTX 4090 and RTX 4080 blocks for each of those card families. Just like the other components in the XH405i kit, the GPU waterblock is also iCUE LINK-equipped.

Aimed at a premium market, the full XH405i kit doesn't come cheap: Corsair has set the MSRP at $700 for the complete cooling collection. Meanwhile, the XG7 GPU waterblock is priced at $230 for all four models.

The iCUE LINK XH405i kit is available now at Newegg and Amazon, as well as through Corsair’s own website.

ASML Delivers First 2nm-Generation Low-NA EUV Tool, the Twinscan NXE:3800E Anton Shilov

Our avid readers tend to look at microelectronics made using leading edge process technologies, which in case of Intel means usage of High-NA extreme ultraviolet (EUV) lithography a couple of years down the road. But the vast majority of chips that we are going to use in the next couple of years will be made using Low-NA EUV litho tools. This is why the latest announcement from ASML is particularly notable.

As spotted by Computerbase, ASML this week has delivered its first updated Twinscan NXE:3800E lithography machine for fab installation. The latest iteration of the company's line of 0.33 numerical aperture (Low-NA) lithography scanners, the NXE:3800E is aimed at making chips on 2nm and 3nm-class technologies.

ASML has not published the full details on the capabilities of the machine, but previous roadmaps from the company have indicated that the updated 3800E would offer both improved wafer throughput and increased wafer alignment precision – what ASML refers to as "matched-machine overlay". Based on that roadmap, ASML is expecting to crack 200 wafers per hour with their fifth-generation low-NA EUV scanner, which would mark a significant milestone for the technology, as one of the drawbacks of EUV lithography since the beginning has been its lower throughput rate compared to today's extremely well-researched and tuned deep UV (DUV) machines.

For ASML's logic and memory fab customers – a list these days that is only around half a dozen companies in total – the updated scanner will help these foundries continue to improve and expand their production of leading-edge chips. Even with major fabs in the midst of scaling-up their operations with additional facilities, improving throughput at existing facilities remains an important factor in meeting capacity demands, as well as bringing down production costs (or at least, keeping them in check).

Though as EUV scanners don't come cheap – a typical scanner costs some $180 million and the Twinscan NXE:3800E will likely cost more – it'll take a while to fully amortize these machines. In the meantime, shipping a faster generation of EUV scanners will have significant financial implications for ASML, who is already enjoys the status (and criticism) that comes from being the sole supplier of such a critical tool.

Following the 3800E, ASML has at least one more generation of low-NA EUV scanners in the works, with the development of the Twinscan NXE:4000F. That's expected to be released around 2026.

SiPearl's Rhea-2 CPU Added to Roadmap: Second-Gen European CPU for HPC Anton Shilov

SiPearl, a processor designer supported by the European Processor Initiative, is about to start shipments of its very first Rhea processor for high-performance computing workloads. But the company is already working on its successor currently known as Rhea-2, which is set to arrive sometimes in 2026 in Exascale supercomputers.

SiPearl's Rhea-1 datacenter-grade system-on-chip packs 72 off-the-shelf Arm Neoverse V1 cores designed for HPC and connected using a mesh network. The CPU has an hybrid memory subsystem that supports both HBM2E and DDR5 memory to get both high memory bandwidth and decent memory capacity as well as supports PCIe interconnects with the CXL protocol on top. The CPU was designed by a contract chip designer and is made by TSMC on its N6 (6 nm-class) process technology.

The original Rhea is to a large degree a product aimed to prove that SiPearl, a European company, can deliver a datacenter-grade processor. This CPU now powers Jupiter, Europe's first exascale system that uses nodes powered by four Rhea CPUs and NVIDIA's H200 AI and HPC GPUs. Given that Rhea is SiPearl's first processor, the project can be considered as fruitful.

With its 2nd generation Rhea processors, SiPearl will have to develop something that is considerably more competitive. This is perhaps why Rhea-2 will use a dual-chiplet implementation. Such a design will enable SiPearl to pack more processing cores and therefore offer higher performance. Of course, it remains to be seen how many cores SiPearl plans to integrate into Rhea 2, but at least the CPU company is set to adopt the same design methodologies as AMD and Intel.

Given the timing for SiPearl's Rhea 2 and the company's natural with to preserve software compatibility with Rhea 1, it is reasonable to expect the processor to adopt Arm's Neoverse V3 cores for its second processor. Arm's Neoverse V3 offer quite a significant uplift compared to Neoverse V2 (and V1) and can scale to up to 128 cores per socket, which should be quite decent for HPC applications in 2025 – 2026.

While SiPearl will continue developing CPUs, it remains to be seen whether EPI will manage to deliver AI and HPC accelerators that are competitive against those from NVIDIA, AMD, and Intel.

Best Portable SSDs: March 2024 Ganesh T S

Once the domain of external, bus-powered hard drives, these days the market for external storage has been almost completely consumed by portable SSDs. Rapid technological advancements in NAND flash technology (including the advent of 3D NAND) has allowed their capacity to eclipse 2.5-inch HDDs, all the while multiple improvements in host interface speeds (such as the move from USB 2.0 to 3.0, and onwards to 3.2 Gen 2 / Gen 2x2 / USB4) has made portable SSDs faster and more reliable than the hard drives they replace. All of which has helped to make portable SSDs the go-to solution for external storage, both big and small.

For our latest storage buyer's guide, we've rounded up some of the best portable SSDs we've looked at in the past couple of years. What's hot, what's not, and what's a good deal while still offering reasonable performance? We break that down and make our picks for the best portable SSDs on the market today.

Marvell's 2nm IP Platform Enables Custom Silicon for Datacenters Anton Shilov

Marvell this week introduced its new IP technology platform specifically tailored for custom chips for accelerated infrastructure made on TSMC's 2nm-class process technologies (possibly including N2 and N2P). The platform includes technologies essential for developing cloud-optimized accelerators, Ethernet switches, and digital signal processors.

"The 2nm platform will enable Marvell to deliver highly differentiated analog, mixed-signal, and foundational IP to build accelerated infrastructure," said Sandeep Bharathi, chief development officer at Marvell. "Our partnership with TSMC on our 5nm, 3nm and now 2nm platforms has been instrumental in helping Marvell expand the boundaries of what can be achieved in silicon."

The 2nm platform is built on Marvell's extensive IP portfolio, which includes advanced SerDes capable of speeds beyond 200 Gbps, processor subsystems, encryption engines, SoC fabrics, and high-bandwidth physical layer interfaces. These IPs are crucial for developing and producing a range of devices, such as custom compute accelerators and optical interconnect digital signal processors. These are becoming common building blocks for AI clusters, cloud data centers, and other infrastructures supporting machines used for AI and HPC workloads.

While these IPs are vital for a variety of processors, DSPs, and networking gear, developing them from scratch—especially for TSMC's 2nm-class process technologies that rely on gate-all-around Nanosheet transistors—is hard, time-consuming, and sometimes inefficient, both from a die space and economics point of view. This is where Marvell's IP portfolio promises to be very useful.

Marvell does not outright say that its TSMC 2nm-certified platform is silicon-proven, but given the fact that TSMC has been working with IP providers over N2-compatible IPs for quite some time, it is reasonable to expect that at least some of Marvell's popular IPs are.

"We take a modular approach to semiconductor design R&D, focusing first on qualifying foundational analog, mixed-signal IP and advanced packaging that can be used across a broad spectrum of devices," Bharathi said. "This allows us to bring innovations such as process manufacturing advances faster to market."

Meanwhile, Marvell is not part of TSMC's Open Innovation Platform and OIP's IP Alliance, so it is unclear whether the company's N2-compatible IPs will be part of TSMC's TSMC9000 IP program, which greatly simplifies IP choices for chip designers.

"TSMC is pleased to collaborate with Marvell in pioneering a platform for advancing accelerated infrastructure on our 2nm process technology," said Kevin Zhang, senior vice president of business development at TSMC. "We are looking forward to our continued collaboration with Marvell in the development of leading-edge connectivity and compute products utilizing TSMC's best-in-class process and packaging technologies."

Intel CEO Pat Gelsinger to Deliver Computex Keynote, Showcasing Next-Gen Products Anton Shilov

Taiwan External Trade Development Council (TAITRA), the organizer of Computex, has announced that Pat Gelsinger, chief executive of Intel, will deliver a keynote at Computex 2024 on June 4, 2024. Focusing on the trade show's theme of artificial intelligence, he will showcase Intel's next-generation AI-enhanced products for client and datacenter computers.

According to TAITRA's press release, Pat Gelsinger will discuss how Intel's product lineup, including the AI-accelerated Intel Xeon, Intel Gaudi, and Intel Core Ultra processor families, opens up new opportunities for client PCs, cloud computing, datacenters, and network and edge applications. He will also discuss superior performance-per-watt and lower cost of ownership of Intel's Xeon processors, which enhance server capacity for AI workloads.

The most intriguing part of Intel's Computex keynote will of course be the company's next-generation AI-enhanced products for client and datacenter computers. At this point Intel is prepping numerous products that pose a lot of interest, including the following:

  • Arrow Lake and Lunar Lake processors made on next-generation process technologies for desktop and mobile PCs and featuring all-new microarchitectures;
  • Granite Rapids CPUs for datacenters based on a high-performance microarchitecture;
  • Sierra Forest processors with up to 288 cores for cloud workloads based on codenamed Crestmont energy-efficient cores;
  • Gaudi 3 processors for AI workloads that promise to quadruple BF16 performance compared to Gaudi 2.
  • Battlemage graphics processing units.

All of these products are due to be released in 2024-2025, so Intel could well demonstrate them and showcase their performance advantages, or even formally launch some of them, at Computex. What remains to be seen is whether Intel will also give a glimpse at products that are further away, such as Clearwater Forest and Falcon Shores.

Variable Refresh Rate Support Comes to NVIDIA’s GeForce Now Cloud Streaming Service Matthew Connatser

Today NVIDIA has brought variable refresh rate support to its GeForce Now cloud gaming service. The company initially promised variable refresh support on GeForce Now back in early January during CES, and has seemingly waited so that it could launch alongside GeForce Now Day Passes, which are also now available.

Variable refresh rate (VRR) technologies, including NVIDIA's own G-Sync, have been around for around a decade now, and allow a monitor to synchronize its refresh rate to the instantaneous framerate of a game. This synchronization prevents screen tearing, when two or more frames are present on a display at the same time. Without a VRR technology, gamers either have to tolerate the visual incongruity of screen tearing or enable V-Sync, which solves screen tearing by locking the framerate to the refresh rate (or a fraction thereof). VRR became popular because V-Sync added latency and could depress framerates due to it effectively being a framerate limiter.

Dubbed "Cloud G-Sync", NVIDIA touts not only a screen tearing-free experience for GeForce Now thanks to variable refresh rate support, but also lower latency thanks to “varying the stream rate to the client, driving down total latency on Reflex-enabled games.” Prior to VRR’s debut on GeForce Now, users either had to enable V-Sync in-game, enable a stream-level V-Sync setting that had the benefit of not locking the game framerate, or accept screen tearing. GeForce Now Ultimate members will also be able to pair VRR with Reflex-powered 60 FPS and 120 FPS streaming modes.

According to NVIDIA’s technical documentation, variable refresh rate support on GeForce Now can work with both Mac and Windows PCs hooked up to a VRR-capable monitor. This includes G-Sync monitors on Windows, as well as VESA AdaptiveSync/FreeSync monitors, HDMI 2.1 VRR displays, and even Apple ProMotion displays, such as the panels built into their recent MacBook Pro laptops. The biggest compatibility hurdle at this time is actually on the GPU side of matters; Windows machines need an NVIDIA GPU to use VRR with GeForce Now. Intel and AMD GPUs are "not supported at this time."

Although G-SYNC originally came out in 2013 and GeForce Now has been available since 2015, the two never intersected until now. It’s not clear why NVIDIA waited so long to bring G-Sync to GeForce Now; the company’s original announcement merely states “newly improved cloud G-SYNC technology goes even further,” implying that it wasn’t possible before but doesn’t exactly explain why.

V-Color Has New RDIMM Octo-Kits For Threadripper 7000 CPUs: 768 GB Kits Starting at $4,840 Zhiye Liu

V-Color has launched several EXPO-certified DDR5 RDIMM memory kits for AMD's Ryzen Threadripper 7000 Pro and non-Pro platforms. The new RDIMM memory kits, which only come in an eight-DIMM configuration, will enable workstation users to push the limits on the WRX90 platform with frequencies up to DDR5-7200 and memory kit capacities up to a staggering 768 GB (8 x 96 GB).

These are your typical run-of-the-mill modules without the fancy heatsinks and flashy RGB lighting. The recipe for the RDIMMs revolves around a 10-layer PCB paired with SK hynix's DRAM chips. And as the Threadripper platforms are all one DIMM per channel (1DPC) designs, V-Color's octo-kits are intended to populate all the memory slots on the WRX90 motherboard in one go.

V-Color is offering their RDIMM kits in several capacities and frequencies, with kit capacities ranging from 128 GB (8 x 16 GB) up to 768 GB (8 x 96 GB), while clockspeeds start at DDR5-5600 and top out at DDR5-7200.

Typical for RDIMM kits, the maximum frequency will vary depending on the memory kit capacity. There are two factors to consider: binning costs and achieving stability at faster frequencies on higher capacities is more challenging for the processor. Ryzen Threadripper 7000 Pro and non-Pro chips officially support DDR5-5200 memory modules. Anything higher is overclocking; stability depends on the processor's integrated memory controller (IMC) quality. DDR5-7200 is only available on V-Color's 128 GB, 192 GB, and 256 GB memory kits. Meanwhile, the 512 GB and 768 GB memory kits top out at DDR5-6000.

128 GB 8 x 16 GB DDR5-5600 - DDR5-7200 CL 32 - CL 36 1.25 V - 1.40 V $1,049.99 - $1,669.99

The DDR5-5600 and DDR5-6000 memory kits are the only ones rated to run at a relatively modest 1.25 V. The higher-end ones require 1.40 V due to the higher frequency and tighter memory timings. The memory timings on V-Color's RDIMM memory kits are decent, though they're far from rivaling premium DDR5 mainstream memory kits. The DDR5-5600 memory kit has 36-38-38-38-80 timings, whereas the DDR5-6000 and DDR5-6400 memory flaunts 32-39-39-102 timings. At the same time, V-Color binned the DDR5-6600 and DDR5-6800 memory kits for 34-46-46-92 and the DDR5-7000 and DDR5-7200 memory kits for 34-43-43-102 and 36-46-46-112, respectively.

V-Color's RDIMM products are overclocked memory kits with a limited lifetime warranty. They come with AMD EXPO support to facilitate one-click memory overclocking. The memory kits are built specifically for the WRX90 platform but should work on Intel platforms (your mileage will vary, of course). Regarding the QVL, V-Color has validated the brand's overclocked RDIMMs on the Asus Pro WS WRX90E-Sage SE and the ASRock WRX90 WS Evo, motherboards that cost over $1,000.

The 128 GB DDR5-5600 memory kit is the most affordable out of the lot, with an MSRP of $1,049.99, whereas the 192 GB counterpart sells for $1,579.99. At the other end of the spectrum, the flagship 768 GB DDR5-6000 memory kit has an hefty $4,919.99 price tag. V-Color's RDIMM memory kits are up for pre-order on the company's online store, and the vendor will ship orders on March 15. The memory kits will be available worldwide through official distribution partners on the same date.

Intel to Hold Webinar to Discuss Long-Term Vision for Foundry, Separating Fab and Design Reporting Anton Shilov

As Intel prepares to move its fabs into its new Intel Foundry business, it will change the way it reports results in the coming months. To discuss the company's long-term vision and give investors a better understanding of how Intel's business will move forward with Intel Foundry and Intel Products groups, Intel plans to host a webinar on segment reporting on April 2, 2024.

"The webinar will discuss the longer-term vision for the foundry business and the importance of establishing a foundry-like relationship between Intel Foundry, Intel's manufacturing organization, and Intel Products, its product business units, to drive greater transparency and accountability," the description of the event reads.

The company plans to submit an 8-K form, revising its past financial reports to align with a new reporting framework, before the upcoming investor webinar. Starting with Q1 FY2024, Intel will disclose its financial outcomes using this new reporting structure.

One of the things that Intel will touch upon at the webinar is the financial and market performance of the Intel Foundry division. These things may not impress. It is likely that initially, Intel Foundry's business will have high costs, and the majority of orders will come from Intel itself (i.e., a significant but still relatively low market share). Meanwhile, Intel Foundry has to invest in advanced fab tools to prep its fabs for 20A and 18A, which drives its costs up, and this likely means losses.

Yet, it will take some time before Intel Foundry obtains revenue streams from major customers, such as Microsoft or the U.S. military. IF's financial numbers and market share may still not impress immediately, but this is normal at this stage. This is perhaps what Intel will communicate and discuss at its upcoming webinar.

In fact, although Intel fully expects its 18A (1.8nm-class) fabrication process to be ahead of its rivals in terms of power, performance, and area (PPA), the company's chief financial officer reiterated at a conference this week that it does not expect to win the bulk of any large customer's chip orders with this technology.

"We probably will not win anybody's major volume [with] 18A," said David Zisner, CFO of Intel, at the Morgan Stanley Technology, Media, and Telecom Conference (via SeekingAlpha). "We will win some smaller SKUs, and that is all we need, to be honest with you. That will be very significant to us, even though it seems maybe marginal in the marketplace, particularly if we can collect enough of these customers [developing high-performance compute chips]."

Intel's 18A fabrication process builds upon the company's 20A manufacturing technology (a 2nm-class node) that introduces RibbonFET gate-all-around transistors and PowerVia backside power delivery network. In GAA transistors, horizontal channels are fully encased by gates. These channels are built using epitaxial growth and selective removal, enabling adjustments in width for enhanced performance or lower power use. As for the backside power delivery network (BS PDN), the technique moves power lines to the wafer's back, separating them from I/O wiring, which allows for making power vias thicker and reducing their resistance, which helps to both increase transistor performance and lower power consumption.

Both GAA transistors and BS PDN promise to offer significant performance and power efficiency enhancements, which is good for AI, HPC, and smartphone SoCs. Meanwhile, 18A promises a 10% performance per watt improvement over 20A and GAA innovations. Thus, it promises to be quite competitive compared to TSMC's N3B and N3P.

"When it comes to the high-performance compute part of the market, that is really where we are starting to see a lot of our uptake," said Zisner. "The particular aspects of 18A with PowerVia and RibbonFET, combined with our just legacy of experience on high-performance compute, I think, makes us a really compelling partner for customers that are in that space and want to develop products."

Intel's 18A was designed to be a major foundry node, and consequently, its process design kit (PDK) is now available and the production technology is compatible with third-party electronic design automation (EDA) and simulation tools. However, Intel itself does not expect this process to be used for high-volume products of third parties. Even Microsoft is currently only slated to produce one chip on Intel's 18A.

Intel Foundry is a newcomer to the contract chipmaking market. As a result, Intel is planning for a multi-generational effort to break into the market, as the company will need to earn the confidence and business of third-party customers. As this happens, Intel Foundry expects to gain market share and reach profitability.

Western Digital Issues Update on Company Split: CEOs for Post-Split Entities Announced Anton Shilov

Now well in the midst of executing its plan to divide itself into separate hard drive and NAND businesses, Western Digital today offered a fresh update on the state of that split, and what the next steps are for the company. With the eventual goal of dividing the company into two independent, publicly traded companies, Western Digital is reporting that they have made significant progress in key transactional projects, and they are also announcing their initial leadership appointments for the post-separation businesses.

Western Digital's separation, announced on October 30, 2023, aims to create two focused companies with distinct product lineups for hard drives and NAND flash memory, respectively, as well as NAND flash memory-based products. This move is expected to speed up innovation and introduce new growth opportunities, according to Western Digital. Meanwhile, with separate capital structures, operational efficiency of the two entities will be higher compared to the united company, the management of Western Digital claims.

Western Digital led the storage industry's consolidation by acquiring HGST, various SSD and flash companies in the early 2010s, and SanDisk in 2016 for NAND flash production. As a result, in late 2010s the company become a media-agnostic, vertically-integrated storage technology company. However, the company faced challenges in growing its revenue. The 3D NAND and SSD markets are highly competitive commodity markets, and as a result they tend to fluctate depending on supply and demand. Meanwhile, demand for HDDs is declining and offseting decreasing unit sales with 3D NAND-based products and nearline hard drives was challenging. Meanwhile, to avoid avoid competition with larger storage solutions providers like Dell, HPE, and IBM — which purchase Western Digital's HDDs, SSDs, and NAND memory — Western Digital had to divest its storage solutions, which presents additional challenges.

As a result, Western Digital's HDD and NAND businesses have acted largely independently since late 2020, when it became apparent that the combined company has failed to become bigger than the sum of Western Digital and SanDisk parts. So far, quite some progress has been made in preparing for the separation, including establishing legal entities in 18 countries, preparing independent financial models, and finalizing preparations for regulatory filings. As a result, the company remains on track to finish the split in the second-half of this year, according to Western Digital.

With regards to post-split leadership, David Goeckeler has been appointed as the chief executive designate for the NAND flash memory spinoff company. He expressed enthusiasm for the NAND business's potential in market growth and the development of new memory technologies.

"Today's announcement highlights the important steps we are making towards the completion of an extremely complex transaction that incorporates over a dozen countries and spans data storage technology brands for consumers to professional content creators to the world’s leading device OEMs and the largest cloud providers," said David Goeckeler, CEO of Western Digital. "I am pleased with the exceptional work the separation teams have done so far in creating a spin-ready foundation that will ensure a successful transition to independent, market-leading companies for our Flash and HDD businesses."

Meanwhile, Irving Tan, currently executive vice president of global operations, will assume the CEO role for the standalone HDD company, which will continue to operate under the Western Digital brand. It is unclear where Ashley Gorakhpurwalla, currently the head of WDC's HDD business unit, will end up, or if he'll even remain with the company at all.

"While both Western Digital's businesses will have the strategic focus and resources to pursue exciting opportunities in their respective markets once the separation is complete, the Flash business offers exciting possibilities with market growth potential and the emerging development of disruptive, new memory technologies," added Goeckeler. "I am definitely looking forward to what's next for the spinoff team."

JEDEC Publishes GDDR7 Memory Spec: Next-Gen Graphics Memory Adds Faster PAM3 Signaling & On-Die ECC Ryan Smith & Anton Shilov JEDEC on Tuesday published the official specifications for GDDR7 DRAM, the latest iteration of the long-standing memory standard for graphics cards and other GPU-powered devices. The newest generation of GDDR brings a combination of memory capacity and memory bandwidth gains, with the later being driven primarily by the switch to PAM3 signaling on the memory bus. The latest graphics RAM standard also boosts the number of channels per DRAM chip, adds new interface training patterns, and brings in on-die ECC to maintain the effective reliability of the memory.

“JESD239 GDDR7 marks a substantial advancement in high-speed memory design,” said Mian Quddus, JEDEC Board of Directors Chairman. “With the shift to PAM3 signaling, the memory industry has a new path to extend the performance of GDDR devices and drive the ongoing evolution of graphics and various high-performance applications.”

GDDR7 has been in development for a few years now, with JEDEC members making the first disclosures around the memory technology about a year ago, when Cadence revealed the use of PAM3 encoding as part of their validation tools. Since then we've heard from multiple memory manufacturers that we should expect the final version of the memory to launch in 2024, with JEDEC's announcement essentially coming right on schedule.

As previously revealed, the biggest technical change with GDDR7 comes with the switch from two-bit non-return-to-zero (NRZ) encoding on the memory bus to three-bit pulse amplitude modulating (PAM3) encoding. This change allows GDDR7 to transmit 3 bits over two cycles, 50% more data than GDDR6 operating at an identical clockspeed. As a result, GDDR7 can support higher overall data transfer rates, the critical component to making each generation of GDDR successively faster than its predecessor.

GDDR Generations
  GDDR7 GDDR6X
(Non-JEDEC)
GDDR6
B/W Per Pin 32 Gbps (Gen 1)
48 Gbps (Spec Max)
24 Gbps (Shipping) 24 Gbps (Sampling)

Total B/W (256-bit bus) 1024 GB/sec 768 GB/sec 768 GB/sec

Data Rate QDR QDR QDR
Signaling PAM-3 PAM-4 NRZ (Binary)
Maximum Density 64 Gb 32 Gb 32 Gb
Packaging 266 FBGA 180 FBGA 180 FBGA

The first generation of GDDR7 is expected to run at data rates around 32 Gbps per pin, and memory manufacturers have previously talked about rates up to 36 Gbps/pin as being easily attainable. However the GDDR7 standard itself leaves room for even higher data rates – up to 48 Gbps/pin – with JEDEC going so far as touting GDDR7 memory chips "reaching up to 192 GB/s [32b @ 48Gbps] per device" in their press release. Notably, this is a significantly higher increase in bandwidth than what PAM3 signaling brings on its own, which means there are multiple levels of enhancements within GDDR7's design.

Digging deeper into the specification, JEDEC has also once again subdivided a single 32-bit GDDR memory chip into a larger number of channels. Whereas GDDR6 offered two 16-bit channels, GDDR7 expands this to four 8-bit channels. The distinction is somewhat arbitrary from an end-user's point of view – it's still a 32-bit chip operating at 32Gbps/pin regardless – but it has a great deal of impact on how the chip works internally. Especially as JEDEC has kept the 256-bit per channel prefetch of GDDR5 and GDDR6, making GDDR7 a 32n prefetch design.

The net impact of all of this is that, by halving the channel width but keeping the prefetch size the same, JEDEC has effectively doubled the amount of data that is prefetched per cycle of the DRAM cells. This is a pretty standard trick to extend the bandwidth of DRAM memory, and is essentially the same thing JEDEC did with GDDR6 in 2018. But it serves as a reminder that DRAM cells are still very slow (on the order of hundreds of MHz) and aren't getting any faster. So the only way to feed faster memory buses is by fetching ever-larger amounts of data in a single go.

The change in the number of channels per memory chip also has a minor impact on how multi-channel "clamshell" mode works for higher capacity memory configurations. Whereas GDDR6 accessed a single memory channel from each chip in a clamshell configuration, GDDR7 will access two channels – what JEDEC is calling two-channel mode. Specifically, this mode reads channels A and C from each chip. It is effectively identical to how clamshell mode behaved with GDDR6, and it means that while clamshell configurations remain supported in this latest generation of memory, there aren't any other tricks being employed to improve memory capacity beyond ever-increasing memory chip densities.

On that note, the GDDR7 standard officially adds support for 64Gbit DRAM devices, twice the 32Gbit max capacity of GDDR6/GDDR6X. Non-power-of-two capacities continue to be supported as well, allowing for 24Gbit and 48Gbit chips. Support for larger memory chips further pushes the maximum memory capacity of a theoretical high-end video card with a 384-bit memory bus to as high as 192GB of memory – a development that would no doubt be welcomed by datacenter operators in the era of large language AI models. With that said, however, we're still regularly seeing 16Gbit memory chips used on today's memory cards, even though GDDR6 supports 32Gbit chips. Coupled with the fact that Samsung and Micron have already disclosed that their first generation of GDDR7 chips will also top out at 16Gbit/24Gbit respectively, it's safe to say that 64Gbit chips are pretty far off in the future right now (so don't sell off your 48GB cards quite yet).

For their latest generation of memory technology, JEDEC is also including several new-to-GDDR memory reliability features. Most notably, on-die ECC capabilities, similar to what we saw with the introduction of DDR5. And while we haven't been able to get an official comment from JEDEC on why they've opted to include ECC support now, its inclusion is not surprising given the reliability requirements for DDR5. In short, as memory chip densities have increased, it has become increasingly hard to yield a "perfect" die with no flaws; so adding on-chip ECC allows memory manufacturers to keep their chips operating reliably in the face of unavoidable errors.

Internally, the GDDR7 spec requires a minimum of 16 bits of parity data per 256 bits of user data (6.25%), with JEDEC giving an example implementation of a 9-bit single error correcting code (SEC) plus a 7-bit cyclic redundancy check (CRC). Overall, GDDR7 on-die ECC should be able to correct 100% of 1-bit errors, and detect 100% of 2-bit errors – falling to 99.3% in the rare case of 3-bit errors. Information about memory errors is also made available to the memory controller, via what JEDEC terms their on-die ECC transparency protocol. And while technically separate from ECC itself, GDDR7 also throws in another memory reliability feature with command address parity with command blocking (CAPARBLK), which is intended to improve the integrity of the command address bus.

Otherwise, while the inclusion of on-die ECC isn't likely to have any more of an impact on consumer video cards than its inclusion had for DDR5 memory and consumer platforms there, it remains to be seen what this will mean for workstation and server video cards. The vendors there have used soft ECC on top of unprotected memory for several generations now; presumably this will remain the case for GDDR7 cards as well, but the regular use of soft ECC makes things a lot more flexible than in the CPU space.


This figure is reproduced, with permission, from JEDEC document JESD239, figure 152

Finally, GDDR7 is also introducing a suite of other reliability-related features, primarily related to helping PAM3 operation. This includes core independent LFSR (linear-feedback shift register) training patterns with eye masking and error counters. LFSR training patterns are used to test and adjust the interface (to ensure efficiency), eye masking evaluates signal quality, and error counters track the number of errors during training.

Technical matters aside, this week's announcement includes statements of support from all of the usual players on both sides of the isle, including AMD and NVIDA, and the Micron/Samsung/SKhynix trifecta. It goes without saying that all parties are keen to getting to use or sell GDDR7 respectively, given the memory capacity and bandwidth improvements it will bring – and especially in this era where anything aimed at the AI market is selling like hotcakes.

No specific products are being announced at this time, but with Samsung and Micron having previously announced their intentions to ship GDDR7 memory this year, we should see new memory (and new GPUs to pair it with) later this year.

Apple Launches M3-Based MacBook Air 13 and 15: 3nm CPU for the Masses Anton Shilov

Apple on Monday introduced its new generation MacBook Air laptops based on the company's most-recent M3 system-on-chip (SoC). The new MacBook Air notebooks come in the same sizes as the previous models – 13.6 inches and 15.3 inches – with prices starting from $1,099 and $1,299 respectively.

The key improvement in Apple's 2024 MacBook Air laptops is of course the M3 processor. Fabbed on TSMC's N3B process, Apple's latest mainstream SoC was first launched late last year as part of the 2023 MacBook Pro lineup, and is now being brought down to the MacBook Air family. The vanilla M3 features four high-performance cores operating at up to 4.05 GHz, four energy-efficient cores, a 10 core GPU based on the latest graphics architecture (with dynamic caching, hardware-accelerated ray tracing, and hardware-accelerated mesh shading), and a new media engine with hardware-accelerated AV1 decoding.

Like prior vanilla M-series SoC, the M3 offers two display engines, allowing it to drive up to two displays. Normally this has been one internal and one external display, but new to the M3/2024 MBAs, the laptop can also drive two external 5K displays when the internal display is disabled (e.g. the lid's closed).

With regards to performance, Apple is opting to compare the new AIrs to the 2020 models with Apple's M1 SoC. The CPU is said to be up to 35% – 60% faster compared to the original M1 chip depending on the workload, but such comparisons should be taken with a grain of salt as companies tend to overhype their biggest advantages. One thing to keep in mind is that since MacBook Airs come without active cooling, their performance is typically lower than MacBook Pros running the same processor.

The SoC supports up to 24 GB of LPDDR5-6400 memory (featuring bandwidth of 100 GB/s), though entry-level MacBook Air models still feature only a diminutive 8 GB of RAM and a 256 GB SSD. More advanced (and usable) configurations offer 16 GB or 24 GB of memory and up to 2 TB of solid-state storage.

Other improvements of Apple's 2024 MacBook Air laptops based on the M3 processor compared to predecessors include Wi-Fi 6E support;  improved three-microphones array with enhanced voice clarity, voice isolation, and wide spectrum modes.

As for input/output capabilities, the new MacBook Air notebooks feature two Thunderbolt 4/USB-C ports, a MagSafe port for charging, a 3.5-mm jack for headsets, and a 1080p FaceTime HD camera.

The 2024 Apple MacBook Air come in midnight, starlight, silver, and space gray colors. The machines are equipped with a 52.6 Wh battery that provides up to 18 hours of video playback. The 13.6-inch machine is 0.44 inch (1.13 cm) thick and weighs 2.7 pounds (1.24 kilograms), whereas the 15.3-inch laptop is 0.45 inch (1.15 cm) thick and weighs 3.3 pounds (1.51 kilograms).

With the launch of its M3-based MacBook Airs, Apple will discontinue its M2-based MacBook Air 15, but will retain the M2-based MacBook Air 13 as their entry-level option, with prices now starting at $999.

SK Hynix Mulls 'Differentiated' HBM Memory Amid AI Frenzy Anton Shilov

SK Hynix and AMD were at the forefront of the memory industry with the first generation of high bandwidth memory (HBM) back in 2013 – 2015, and SK Hynix is still leading this market in terms of share. In a bid to maintain and grow its position, SK Hynix has to adapt to the requirements of its customers, particularly in the AI space, and to do so it's mulling over how to make 'differentiated' HBM products for large customers.

"Developing customer-specific AI memory requires a new approach as the flexibility and scalability of the technology becomes critical," said Hoyoung Son, the head of Advanced Package Development at SK Hynix in the status of a vice president

When it comes to performance, HBM memory with a 1024-bit interface has been evolving fairly fast: it started with a data transfer rate of 1 GT/s in 2014 – 2015 and reached upwards of 9.2 GT/s – 10 GT/s with the recently introduced HBM3E memory devices. With HBM4, the memory is set to transit to a 2048-bit interface, which will ensure steady bandwidth improvement over HBM3E.

But there are customers which may benefit from differentiated (or semi-custom) HBM-based solutions, according to the vice president.

"For implementing diverse AI, the characteristics of AI memory also need to become more varied," Hoyoung Son said in an interview with BusinessKorea. "Our goal is to have a variety of advanced packaging technologies capable of responding to these changes. We plan to provide differentiated solutions that can meet any customer needs."

With a 2048-bit interface, many (if not the vast majority) of HBM4 solutions will likely be custom or at least semi-custom based on what we know from official and unofficial information about the upcoming standard. Some customers might want to keep using interposers (but this time they are going to get very expensive) and others will prefer to install HBM4 modules directly on logic dies using direct bonding techniques, which are also expensive.

Making differentiated HBM offerings requires sophisticated packaging techniques, including (but certainly not limited to) SK Hynix's Advanced Mass Reflow Molded Underfill (MR-RUF) technology. Given the company's vast experience with HBM, it may well come up with something else, especially for differentiated offerings.

"For different types of AI to be realized, the characteristics of AI memory also need to be more diverse," the VP said. "Our goal is to have a range of advanced packaging technologies to respond to the shifting technological landscape. Looking ahead, we plan to provide differentiated solutions to meet all customer needs."

The Cooler Master MWE V2 Gold 750W PSU Review: Effective, But Limited By Aging Platform E. Fylladitakis Cooler Master, renowned for its pioneering role in cooling technologies, has evolved into a key player in the PC components industry, extending its expertise to include cases and power supply units (PSUs). The company's current catalog is a testament to its commitment to diversity, featuring over 75 PC cases, 90 coolers, and 120 PSUs, all designed to cater to the evolving demands of tech enthusiasts and professionals alike.

This review focuses on the Cooler Master MWE Gold V2 750W PSU, a key offering in Cooler Master's power supply lineup that embodies the brand's vision of combining quality and value. The MWE Gold V2 series is engineered to offer solid performance and reliability at a price point that appeals to system builders and gamers looking for an entry-level to mid-range solution. As a result, the MWE Gold V2 750W has been a consistently popular offering within Cooler Master's catalog, often cycling in and out of stock depending on what sales are going on. This makes the PSU a bit harder to track down in North America than it does Europe, and quick to vanish when it does show up.
