Intel Launches 7th Generation Kaby Lake: 15W/28W with Iris, 35-91W Desktop and Mobile Xeon

With the vPro variants of Kaby Lake, Intel is announcing the launch of Intel Authenticate. This is a hardware driven protection system designed to offer more security for user authentication, such as hardware based biosensors (iris, fingerprint) or location based (Bluetooth) security. Similar to how other hardware authentication based systems work, the vPro CPUs will have Intel’s Security and Software Guard Extensions (SGX) enabled to be able to isolate various instruction workflows and also detect when potential intrusion occurs. Intel did not go into any significant detail here, probably based on the initial audience for the Kaby Lake launch being more consumer oriented, but we were told that Intel is working with popular password managers to offer a more secure environment.
The vPro capable processors available from today are the i7-5Y75, i7-5Y57, i7-7600U, i7-7300U, i7-6660U, i5-7350U, E3-1535M v6, E3-1505M v6, i7-7920HQ, i7-7820HQ, i5-7440HQ, i7-7700, i5-7600, i5-7500, i7-7700T, i5-7600T and i5-7500T. These processors need to use the Q270 chipset in order to have vPro capabilities.
OPI 2.0 to OPI 3.0
From the Kaby Lake-Y/U Launch
For anyone following our NUC testing, you may remember that during testing of a Skylake-Y NUC, we found that the PCIe 3.0 x4 slot for M.2 drives was actually limited to PCIe 2.0 x4, effectively reducing the peak bandwidth. At the time we probed Intel and our data sheets to find out that it was actually a limitation imposed by Intel on the CPU which wasn’t obvious from the original launch materials. The interconnect between the CPU cores/system agent and the integrated chipset, what we normally call DMI on a desktop platform but is called OPI on an SoC, was fixed at PCIe 2.0 speeds.
We asked about why this was the case, and we were told that the system actually can support PCIe 3.0 x4 speeds, and the system even tests this on startup, but for stability PCIe 2.0 is chosen. This made the marketing of the NUC a little confusing, especially as PCIe 3.0 x4 for storage was listed as a feature. Working with Intel, they pushed through a new BIOS for the NUC that kept the OPI at PCIe 3.0 x4 speeds, and we were able to get peak bandwidth from our storage devices. However, that BIOS update was limited to one mini-PC from one vendor, leaving all the other vendors to do their own thing.
This time around, Intel is doing the change by default (on every KBL processor, except the Core i3-7100U). The interconnect to the chipset now runs at PCIe 3.0 x4 speeds, allowing the integrated chipset to offer full PCIe 3.0 lanes for extra controllers, storage and other features. For the Y series, this means 10 PCIe 3.0 lanes and the U series get 12 lanes. We could end up seeing some Core i5/i7 devices offer dual M.2 PCIe 3.0 x4 RAID as a result, depending on compatibility. Intel also lists NVMe support for the five processors on OPI 3.0.

Considering the minimum cores you get per module is 4, I see AMD selling months later a 3c/6t cpu for $99.They will make a tweak for the raven ridge APU since the core count for those is 4c max.

Every segment they don't cover (and they don't have Zen APUs yet) is business left on the table - the budget segment is big enough and in regions they care about.Maybe they should go to 49$ with quads and disable HT, some cache but it is likely that if they don't do that, most would make an effort to get the 99$ quad. Just hope they don't get too greedy and start way higher, Intel can make quads without a GPU too, won't take too long and AMD needs to exploit this window of opportunity and gain,not just revenue, but hearts and minds.

"We still have not received an official word if Intel is working closely with Apple to bring the feature to macOS, or even if it will be promoted if it ever makes the transition"Could some more-or-less unexpected interaction between Speed Shift 2 and the rest of MacOS be the reason for the apparently random dramatic swings in the battery lifetime of the new MacBook Pros? We hardly know enough to point fingers at either Apple or Intel, but I could certainly imagine that each side has a certain mental model of what the other side is/"should" be doing, and the mismatch between those models means that the CPU is randomly being told to run at maximum speed when the OS actually wants it to dramatically slow down.
I agree that this sounds kinda dumb of the surface, but I could imagine that there are enough layers between UI/framework code, the power driver, the core OS, and EFI, that something gets confused along the way including, perhaps, exposing a bug (again either on the Apple side or the Intel side) that just didn't get triggered (or at least not very often) on either previous x86 CPUs or on Linux/Windows.

My 5 year old 3930k can still basically keep up with Intel's latest and greatest with stock voltage OC. Hum... I used to buy new stuff every year, or every two years at most, because there was normally a good gain to be had. It's legit been 5 years now and my PC with a little work, in multi core tests, is just as fast as anything out there. That's pitiful on Intel's behalf. They've gotten fat and lazy and the consumer is paying for it. Trump needs to tell AMD to put the A back into their chips and actually put out some products at the high-end that actually pushes Intel to be great again.Laststop311 - Wednesday, January 4, 2017 - link
Is it really worth saving 60 dollars to get an unlocked i3 vs the unlocked i5? I really can't see any situation where 60 dollars is the difference between being able to afford a new pc or not. With DX12 it HIGHLY benefits from having 4 cores (really 6 cores is optimum with 8 only slightly improving). Being stuck with 2 cores in this day is severely crippling your lifespan of the pc. You will waste GPU power and be constrained by the 2 cores all in the name to save 60 dollars. Nah it's not worth it.Kaby lake in general is not worth it. Everyone with quad core sandy bridge and above is going to see very minimal gains from a quad core cpu. You really need to go to 6 cores to get any real performance increase and you also need to be playing in dx 12 mode. Your best bet is to wait for the 2019 tock of 10nm coffee lake. Intel will be moving to pci-e 4.0 which doubles the bandwidth so an 8x pci-e 4.0 is the same as a 16x pci-e 3.0. Since gpu's only lose a few percentage points of performance on 8x pci-e 3.0, 8x pci-e 4.0 will give them all the breathing room they need. This leaves you 16x lanes of the 24 lanes to use for m2 storage devices or capture cards without having to use the higher latency PCH pci-e lanes. Or with multi GPU you still have 8x cpu pci-e lanes and you only need 2x pci-e 4.0 lanes to give you 4GB/s (32gbps) so you can fit dual gpu's and 4 pci-e storage devices all connected to the cpu directly and both gpu's will get 16GB/s (128gbps) bandwidth. This gives you massive future proofing. With intel optane maturing you can go single gpu at 16x pci-e 4.0 lanes 32GB/s bandwidth (256gbps) stick an optane drive on 4x lanes giving you a massive 8GB/s (64gbps) and 2 m2 nvme ssd's on 2x lanes each 4GB/s (32gbps) each, with all devices connected directly to CPU for the lowest latency leaving all the PCH lanes free for external ports like TB3 USB 3.1 gen 2 etc.
By waiting till 2019 you get a real upgrade instead of a sidegrade. pci-e 4.0 will unlock the true potential of Intel optane as i expect by then the optane drives will be maxing out the 4x pci-e 3.0 lanes at 4GB/s and pci-e 4.0 will allow optane to really shine and most likely hit 7GB/s or more. With that kinda storage speed you can transfer an entire blu ray disc image in about 7 seconds.
Now by all means if you are still on the Q series quad cores than kaby lake is a compelling upgrade and isn't a total waste of money to upgrade. But even in that circumstance I would say try to stick it out another year so you can have a 6 core coffee lake as 6 cores is incredibly useful in dx12.

You mean upgrade to the 8c/16t Ryzen or wait 2018-2019 for the 7nm Zen+?gopher1369 - Wednesday, January 4, 2017 - link
The only thing that occurs to me is game emulators. Dolphin and PCSX2 require high clock speeds and high IPC, not more cores. It's quite niche, but if you're building an emulator box then the unlocked Anniversary Edition Haswell Pentium is currently the go-to processor, the new i3 should be even better.Laststop311 - Wednesday, January 4, 2017 - link
What applications use AVX instructions? I wonder how much it will hurt performance for some applications by decreasing AVX to 4.0ghz so you can hit 5.0ghz on everything else. The highest overclock i've seen talked about is 5.1ghz on the i7-7700k using the corsair 115ijohnp_ - Wednesday, January 4, 2017 - link
(3) Embedded DisplayPort* (eDP) 1.4 and PSR2 under evaluationI seriously didn't expect that! This means that they actually changed the display pipeline slightly :)
Now, hopefully laptop vendors will make use of PSR2 to further improve battery life.
On a side-note: Does anyone know how to overclock the 7820HK when there's no mobile chipset that supports overclocking? Will laptop vendors have to include the Z270 desktop chipset on their platform?

You open intel XTU and press on the arrows till it BSOD's.Laptop chipsets are "different" in a lot of senses.
