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.

HStewart - Saturday, April 7, 2018 - link"It took a few years before big programs like Photoshop had native Mac Intel ports."
Wrong... Photoshop originally was created on Mac and later ported to Windows.
ARM MacBook would have many challenges - it would also have to be able to run Windows programs and more importantly able to recompile applications for OS on the same machine.
Apple has rumors of attempting an ARM based Mac - but so far ARM is using in display controllers for 5K screens and in iOS products. Apples wants people to believe that iPad Pro's are PC replacements - but they no more that glorified iPad's. The new iPad is good example of this and has same Apple Pencil and probably faster that original iPad Pro.
serendip - Sunday, April 8, 2018 - linkI remember using Photoshop on the first Intel Macbook in 2006, it was translated from PowerPC code using Rosetta. This was in OS X, not Windows. The OS X Intel (Universal) port arrived two years later. The translated version was surprisingly bearable to use on a Macbook even when compared to the PowerPC native port running on a top-spec G4 Powerbook.
Rosetta saved the translated code so it wouldn't be so slow on subsequent running. Apple could do the same thing to get OS X Intel code working on an ARM Macbook, just like what Qualcomm and Microsoft are doing on Windows Snapdragon PCs.
As for coding, Xcode has iOS ARM targets so adding a MacOS ARM variant shouldn't be difficult. I'm not sure about Windows on ARM Macbooks though. Apple might be willing to drive away that user segment because it's so small and niche.
FunBunny2 - Tuesday, April 3, 2018 - link"A non Intel based Mac will never replace high end mac"
again. they've been on 3 processors so far.
HStewart - Saturday, April 7, 2018 - linkI believe Apple makes it's announcements in June They would be foolish not to release the 6 core mobile MacBook Pro update - they would not wanted to compete with new Windows notebooks using 6 cores.
On the Apple move for own CPU, I think it only going release in low end Mac line if so - possible in the iOS line. Apple has always blindly want people to believe iPad Pro are desktop replacements - but until those devices can actually successfully run the Mac development tools that allow developers to create iOS applications, Apple is dream - in any ask espected processing power is expected to be very limited.
Another big concern that Mac line has to live with Windows compatibily - Mac are good for limited purpose - which Apple has been very good at - primary in schools - but also in graphics industry but that is no longer the case. There are other options - especially in schools.
Tyler_Durden_83 - Tuesday, April 3, 2018 - linkWhich sku do you think will power the next nucs (the normal ones, not the gaming oriented hades canyon ofc).
TheBestPessimist - Tuesday, April 3, 2018 - link+1 i'd love to know that as well.
abrowne1993 - Tuesday, April 3, 2018 - linkI don't understand the designation of certain chips as i3, i5, i7, i9 on mobile recently. At least on desktop you can immediately identify how many cores and threads they have (outside of HEDT). It seems so arbitrary on mobile now.
DanNeely - Tuesday, April 3, 2018 - linkIt's always been a lot more arbitrary on mobile with significant spec differences at each branding level depending on the TDP.
edzieba - Tuesday, April 3, 2018 - linkAbsence of Z390 is interesting, many were expecting that alongside the H/Q/B PCHs.
FunBunny2 - Tuesday, April 3, 2018 - linkthey really ought to come up with a different name. this one is a mashup of ancient IBM Big Iron. not, I'd wager, the image they seek.
