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.

AnandTech Cores Base
L3 vPro DRAM
Core i7-8559U $431 4 / 8 2.7 4.5 8 MB No 2400 48 EUs 300 / 1200
Core i5-8269U $320 4 / 8 2.6 4.2 6 MB No 2400 48 EUs 300 / 1100
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.

    What is the target market for the new T-series chips? It's the same price as the chip with iGPU and the lower TDP comes at the cost of lower clock and still no overclocking.

    OEM SFF boxes, like the Dell Optiplex Micro series.

    i9. Mobile. 6 core with no HT.

    Intel ... the i9 branding already is a tortured SKU name. Anything i9 should be auto-badass awesome insaneballs SKU.

    Instead, we get the insult that i9 is not only brought back for ANY SKU, but a mobile SKU. Which is already lying BS marketing SKU (hey, a mobile i7 is actually 2 real cores + HT which in desktop land is a low end i3 but who cares! marketing!).

    While a mobile coffee lake native 6 core with no HT WOULD have been impressive (assuming no tard low base speed) as a very high i5 or i7 mobile... resurrecting the tortured i9 branding with anything less than 12 cores (of any dam*** sort) is insulting.

    FU intel. And FU to all the folks who gobble this up at a premium cause 9 > 7 in mobile land which enables Intel Marketing to justify this ****

    I just have to add, the cynicism in this article from Ian is amazing. That's no insult or judgement - just "holy moly, it's so bad even finally it broke through."

    I don't want to face the reality that PC hardware doesn't mean anything to the average (mass market - quantity) buyer when purchasing their next disposable facebook terminal....

    I don't. .. . .. ... .. *cry*

    It's so bad even AT is kicking Intel to the curb :).

    iX does make sense only inside a segment. You can't suppose, that i7 for ultrabooks is comparable to i7 fo HEDT. This is not a technical term, it's marketing term. If you expect anything else...

    ...yeah. Getting *this* upset about a company's branding strategy is nuts.
  • xrror - Tuesday, April 3, 2018 - link

    fine, i guess I was nuts back when they did this with Sandy Bridge mobile. I'll consider myself chastised and STFU as you wish.

    It bothers me because I'm involved in purchasing PC's for the company. Users always complaining because they bought the marketing and think what we are getting them is crap because it doesn't have an i7 sticker on it.

    Tell them they need to be more productive and waste less time so the company is more profitable an can afford to purchase i7 laptops.
