Coffee Lake with Iris Plus at 28W

Intel recently announced its ‘Intel Core with Radeon RX Vega’ processor line, featuring a H-series processor combined with an AMD graphics chip and a sizeable amount of high-speed HBM2 memory connected via Intel’s proprietary EMIB technology. These parts are designed to service the high-end for integrated graphics, going above and beyond any other integrated graphics solution in the past. That used to be a post held by Intel’s processors that used eDRAM, using the Iris, Iris Pro, and Iris Plus branding. Now the Iris line sits in the middle, acting as Intel’s graphics focused products in the mid-power range.

For the launch today, Intel is lifting the lid on four separate Iris Plus-based processors. These all use the Coffee Lake microarchitecture and are built on Intel’s 14++ process. All four of these processors are in Intel’s ‘GT3e’ graphics configuration, which uses Intel’s Gen 9.5 graphics with 48 execution units (EUs) and 128 MB of eDRAM. This is compared to the GT2 configurations seen on most other processors, that have 24 EUs and zero eDRAM.

Core-i5-8259U $320 4 / 8 2.3 3.8 6 MB No 2400 48 EUs 300 / 1050
Core i3-8109U $304 2 / 4 3.0 3.6 4 MB No 2400 47 EUs 300 / 1000

Intel has split these new CPUs up into a single Core i7-8559U, which is a quad-core processor with the most L3 cache, two Core i5 parts that are also quad-core but have reduced L3 cache, and a Core i3-8109U processor that is dual core, but with the same amount of L3 cache per core as the Core i7-8559U.

In Intel’s manufacturing parlance, this means that the Core i7 and Core i5 are all ‘4+3e’ units, meaning four cores and GT3 graphics with eDRAM. By contrast, the Core i3 is a ‘2+3e’ processor, with only two cores but the same GT3e graphics with eDRAM as the i7/i5. Based on the design of these processors, the Core i3 sits as the lower binned part: it is manufactured as a 4+3e design, but due to processor defects is only suitable to run two cores. As with most of the other mobile processors, the higher performance parts often get the highest frequency graphics as well. In this case, the Core i7-8559U sits at the top at 1200 MHz.

For the eDRAM, in previous generations Intel has moved from going all parts at 128 MB to having some move down to 64 MB, but now moves back up to all of them having 128 MB again. For the eDRAM implementation, Intel is still using their second generation eDRAM implementation whereby the eDRAM acts as a L4 buffer for supplying the L3 from DRAM through the System Agent – this is compared to the first generation where the eDRAM was a victim cache. This methodology allows the eDRAM to speed up more use cases than just graphics, and the 50 GBps bidirectional bandwidth is certainly a big leap over main DRAM bandwidth (that some OEMs run in single channel mode anyway). Iris Plus processors can also be equipped with discrete graphics, although this is up to the OEM.

The 28W Iris Plus processors will match the other mobile counterparts on chipset, and support the new features such as integrated Intel 802.11ac Wi-Fi and native USB 3.1 (10 Gbps) support. We do not know to what extent these are supported, and are waiting on more information. The Iris Pro parts will also support Optane-accelerated storage.

    tl;dr. No consumer line 8-core from Intel yet. Reply

    No need to rush it since Intel still has the performance crown (the best value crown is another matter ofc). Reply

    Not really. The 1800X still beat the 8700K in most multi-threaded workloads. Intel has the crown for best performance if all you do is single player gaming at low resolution. That's about it. Multi-threaded workload and professional workloads Intel is behind. Gaming at higher resolution or streaming it's really a toss up. Reply

    Well. There is a rush.
    There are those who are on Westmere/Sandy Bridge/Ivy Bridge who have 6 core processors but are looking to upgrade, like myself.

    Intel's 6-core mainstream parts aren't really attractive considering I have had a 6-core processor for almost a decade, sure... I will gain a massive increase in single threaded performance... But it's nothing that a little bit of overclocking to 4.8ghz on my 3930K that couldn't make up some of that difference.

    Besides... In heavy threaded scenario's, AMD beats Intel.

    I guess I am waiting another year to upgrade. Another year Intel doesn't get my cash.
    Probably not a bad thing at the moment anyway with the price of DRAM.

    "Westmere/Sandy Bridge/Ivy Bridge who have 6 core processors"

    But those were the extremely high end expensive CPU's back then. Those dont compare with todays standard consumer models, they compare with the Core i9 which has 10 cores https://ark.intel.com/products/123613/Intel-Core-i...

    "In heavy threaded scenario's, AMD beats Intel."

    which matters once we have more than a handful of multi-threaded apps. running discrete apps in background really isn't the same thing.

    Virtually all productivity and real professional programs are nicely multi threaded. And running multiple discrete programs or multiple instances of the same program concurrently is very valid use of multi-threading. Think about what live game streaming involves: all different programs executing concurrently (where each may also be multithreaded): the game, the recording application, the encoder process, the streaming network application, the live audience chatroom, etc Similary with many other cases Reply

    Professional streamers use 2 PC's. 1 for gaming, 1 to capture video and run all the programs. Reply

    They only used 2 PCs because they were literally forced to. Before Ryzen the only option they had was either use very pricey HEDT set up or have a gaming PC and a streaming PC. Often the 2 PC set up would be cheaper. After Ryzen, streamer can easily get by with one PC for everything. Reply

    I could stream with my old FX processor.

    The entire reason I got a 6 core was to multi task. It wasn't the best at everything, but it could do a hell of a lot all at once without slowing down my gaming.

    I regularly would record TV while encoding a video while gaming. Streaming wouldn't be a strain on the machine. It was a purpose built DVR with gaming.
