Intel Expands 8th Gen Core: Core i9 on Mobile, Iris Plus, Desktop, Chipsets, and vProby Ian Cutress on April 3, 2018 3:01 AM EST
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 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.

Ratman6161 - Tuesday, April 3, 2018 - linkI know all about that. Last year we bought a round of thin and light laptops where the users were stamping their feet and insisting they needed i7's. At first I tried hard to explain to them that in the 7th gen mobile "U" cpu's there was practically no difference (and definitely no difference they would notice) between an i7U and an i5U. We bought the i5's and they were P.O'd but they wouldn't have been happy no matter what we gave them. I was very sorely tempted to order a set of Intel i7 Inside stickers to put on them - you can actually buy them on Amazon:)
Icehawk - Thursday, April 5, 2018 - linkMy manager just didn’t understand why I said buying an i7 laptop doesn’t solve our performance problems - we aren’t ordering the 4 core model, not sure why our vendor hasn’t tried to upsell at least. Yes, I want some fries with that dammit.
Chaitanya - Tuesday, April 3, 2018 - linkStupid marketing of i7+ , what's next brainfart from this marketing team?
goatfajitas - Tuesday, April 3, 2018 - linkActually the issues were process related and continued delays on 10nm parts... The marketing is a BS reaction to try and sell more parts and "slap some lipstick on that pig". Most of their customers don't know or care about the differences, they just want the current "i5" or "i7" part and buy it.
nukunukoo - Tuesday, April 3, 2018 - linkHere's to hoping for a surprise 6-core, 32GB Macbook Pro this year...
damianrobertjones - Tuesday, April 3, 2018 - linkNo, no and no. The value of that machine will fall fast once Apple moves to (Add cpu here) in 2020.
goatfajitas - Tuesday, April 3, 2018 - linkLOL. Keep dreaming. Apple has a tiny marketshare and their media strong CPU's are not and will not be a match for Intel in real computing space.
PeachNCream - Tuesday, April 3, 2018 - linkBut there's already a lot of speculation based on a Bloomberg article of a shift starting in 2020 from Intel x86 CPUs to some sort of higher performance ARM processor in order to unify the OS experience across Apple products. Take a look on Google for Kalamata which is the project name. If what looks like leaks are true, there's a change blowing in the wind in Apple's Macintosh product line.
Ratman6161 - Tuesday, April 3, 2018 - linkI doubt it will be a good change if you are a die hard Mac person. As things stand today, no ARM chip is going to match Intel for raw computing power. Power consumption, sure but no where close on raw speed. To me it seems almost like they are getting ready to write off their traditional fan base of graphics people.
PeachNCream - Tuesday, April 3, 2018 - linkI really don't know what to make of this from a performance and compute perspective (or any other perspective for that matter) as I don't own or use a Mac. If its true that Apple is planning to use in-house ARM processors in only a couple of years, then they've probably already been in development for a while and they will need to compete with x86 hardware if they expect to land sales. At this point, I'm just curious about what will happen and how it might or might not shake up the industry.
