Intel Unveils 10th Gen Core Ice Lake-U & Ice Lake-Y Mobile CPUs: 10nm Sunny Cove Later This Yearby Ian Cutress on May 29, 2019 8:00 AM EST
At Intel’s Keynote presentation here at Computex, the company finally lifted the lid on its first widely available new CPU design on its 10nm process, called Ice Lake. The official marketing name for these processors will be ‘Intel 10th Generation Core’, and will feature up to four CPU cores with Intel's new Sunny Cove architecture, new Gen11 graphics supplying up to 1TF of graphics/compute performance, and built in support for Wi-Fi 6 and Thunderbolt 3.
The story of Intel’s 10nm is a long and drawn out one, which we covered when we reviewed the first 10nm CPU, Cannon Lake, which only ended up in some limited Chinese system launch. Fast forward almost 2.5 years from when Intel officially announced it was shipping those 10nm CPUs and we have a full launch of Ice Lake, built on the company's greatly refined second-generation 10+ process. Intel spent a lot of its keynote presentation going through how it has driven the ecosystem and its ecosystem partners around developing systems with the new CPU in mind.
Intel is officially launching 11 different CPUs in the 10th Gen Core lineup, ranging from Core i3 to Core i7. Details on the specifications of those CPUs has not actually been released, which raises a number of questions of how much of a launch this actually is, however we do know that the best CPUs will have a turbo frequency up to 4.1 GHz and a top GPU frequency of 1.1 GHz. Users might consider this lower than 9th Gen mobile parts, which again raises questions. CPUs will be coming to market with 9W, 15W, and 28W variants.
Intel’s partners however have given us some specifications, and it shows in interesting adjustment in the naming scheme.
|OEM-Listed Intel Ice Lake 10nm CPUs|
|i7-1065 G7||4C/8T||1.3 GHz||3.9 GHz||Yes||?||?|
|i5-1035 G1||4C/8T||?||3.7 GHz||Yes||?||?|
|i3-1005 G1||2C/4T||?||3.4 GHz||Yes||?||?|
At this point in time we’re not sure exactly what the ‘G7’ or ‘G1’ means in the name. It could be related to graphics, given that Intel will launch CPUs with 32 EUs, 48 EUs, or 64 EUs.
In accordance with their trio of TDPs, Intel has confirmed that there will be both Y-series and U-series Ice Lake parts. As a refresher, Intel's Y-series parts are their most compact, lowest-power chips, designed for passively cooled devices and other devices with limited cooling options, like 2-in-1s. Y-series chips have a nominal TDP of 9W – notably higher than the 5W TDPs for the current-generation Amber Lake-Y parts – and will be able to cTDP Up to 12W. Meanwhile Intel's U-series will, it appears, be the flag bearer for Ice Lake. These parts will have a nominal TDP of 15W, and can cTDP Up to 25W.
According to Intel's official product brief, both the U-series and Y-series parts will come with integrated GPUs with up to 64 EUs – this being particularly notable since the Y-series parts are going to be so low power. However it looks like Intel is going to split up the U-series a bit; 32 EU parts are listed as "Ice Lake U UHD", while 48 and 64 EU parts are "Ice Lake U Iris Plus". So Intel's Iris Plus branding will remain; and hopefully Iris Plus Ice Lake SKUs will be more common than today's Iris Plus parts.
Intel has discussed Ice Lake to a certain degree back in December and more recently at a private event, which we will be publishing after Computex to give it the attention it deserves. But the new core is designed to have more execution units, wider out-of-order windows, better load/store functionality, a bigger cache arrangement, and Intel states that this is good for an average 18% raw clock-for-clock performance uplift compared to the original Skylake core released in 2016.
Users might be surprised about this 18% number, given that Intel has historically only provided low single digit boosts in recent generations. The reason for those single digit boosts comes down mainly to small parts of the core microarchitecture being widened. For Ice Lake, the doubling of the L2 cache, the increase in execution ports, and the dispatch capabilities of the front end of the core all provide big improvements. Intel also states that the pre-fetchers are improved, which also helps with that 18% IPC increase. It will be interesting to get hold of a system and to actually test/compare with Skylake, especially with all the security patches applied.
For graphics, Intel is stating that the best 10th Gen Core designs will be able to compete with what AMD has to offer with its mobile APU platforms. By increasing the number of execution units from 24 EUs to 64 EUs, Intel is promising over a 2x boost in graphics performance, which is facilitated by the better cache design on the CPU. The new graphics architecture, along with aggressive driver updates, should provide Intel better positioning in the thin-and-light gaming market. Benchmarks shown by Intel include many of the popular titles running today at 1920x1080 at either low or medium settings.
Core functionality aside, the new chips are also incorporating some of the latest I/O features. The biggest news here, of course, is integrated Thunderbolt 3 support for the on-chip 300 series mobile chip, finally doing away with the need for a separate PCIe-to-Thunderbolt controller. Not only will this save laptop OEMs space in their design, but as it's now a baseline feature of Intel's mobile chips, Thunderbolt 3 should become nearly ubiquitous across low-power laptops. Which considering that Thunderbolt 3 has been released to the world at large to be used as the basis for USB4, it's clear that Thunderbolt technology is quickly going to become a necessary feature for future laptops.
The other notable change here is support for Wi-Fi 6 (802.11ax), via Intel's increasingly well-established CNVi program. As with Intel's first-generation integrated Wi-Fi 5 functionality, Wi-Fi 6 is integrated in two parts. The Wi-Fi 6 Media Access Controller (MAC) is on Intel's chipset, meanwhile the RF hardware is on a separate companion module. Going this route is optimal for OEMs for regulatory reasons – the RF module can be certified separately – though it does mean they'll need to buy the RF module to make use of the processor's on-chip Wi-Fi capabilities. Interestingly, neither Intel nor the rest of the industry is wasting any time here; even though the Wi-Fi 6 standard hasn't been fully approved yet – it's still draft – it's already being integrated into hardware wide and far, including now mobile PC processors.
Overall, a number of ecosystem partners are at the Computex show with 10th Gen Core designs, including Dell, HP, Lenovo and others. For this new generation, Intel is also pushing its new Athena project, which we're covering in a separate article.
AnandTech's deep dive coverage of Intel 10th Gen Core will continue after Computex, with more details an analysis of the core microarchitecture. We're also working with Intel to get more access to Ice Lake platforms so we can provide a full testing profile of the new CPU family.

jospoortvliet - Thursday, May 30, 2019 - linkWell intel can wait a long time, AMD lacks a compelling solution that competes with this in the (ultra) portable market... it will take a while until zen2 and Navi come to mobile, long enough perhaps that they even end up competing with whatever intel does next. AMD clearly focuses on enthusiast desktop & server for now, where they can win easily. Sadly for them laptops are a huge market... though of course there is more $$$ in servers.
Targon - Friday, May 31, 2019 - linkTake a look at the clock speeds on these chips. Yes, turbo goes higher, but at 15W, that is base clocks, and turbo we don't know how much power or heat gets generated. AMD SHOULD move up the next generation laptop chips by a few months if possible, because a 7nm Zen2 based laptop chip would destroy these new Intel 10nm laptop chips.
dromoxen - Monday, June 10, 2019 - linkthere is no such thing as an AMD NUC .. (mini-pc) believ me I've looked . A whole segment of the market going begging Under 15w from AMD Mini-Pc would be great ... maybe some day .. when their chip supply improves?
RSAUser - Saturday, June 1, 2019 - linkWasn't the issue with AMD chips something along the lines of not properly ramping up or down, wasting a lot of battery?
Once fixed playing field is even at worst, while AMD is releasing an improved APU based on Navi, just no die shrink.
Santoval - Wednesday, May 29, 2019 - linkThe CPU clocks are going to be quite lower than the 14nm++ equivalents, due to persisting thermal issues and low yields. I have no idea what that means exactly for the iGPU clocks, but I would expect quite lower iGPU clocks as well, or at least much shorter sustained iGPU boost clocks.
Gen11's design is somewhat different though, so we will need to wait for devices to be released to find out how the iGPUs will perform (we already know, based on Intel's own graphs, that Whiskey Lake-U is going to have crappy performance - at best 2% faster than Whiskey Lake-U . Their thermal issues also had to force them to blow up the TDP of the Y parts from 4.5W to 9 - 12 W, which is staggeringly high and probably precludes fanless designs, i.e the designs the Y CPUs are actually meant for...).
Santoval - Wednesday, May 29, 2019 - linkedit : I meant the Sunny Cove cores are going to have crappy performance, not Ice Lake-U by and large.
firewolfsm - Wednesday, May 29, 2019 - linkThe TDP growth from 5->9W for the Y parts can mostly be explained by integrating wifi and thunderbolt 3, which are worth 2W each at least. The cores themselves are most likely being allocated slightly less power than before, and system power consumption will improve.
s.yu - Wednesday, May 29, 2019 - linkDidn't realize Thunderbolt needed so much power.
HStewart - Wednesday, May 29, 2019 - linkIt also could be related to fast iGPU and also does anything stated there is quad core Y Part. The XPS 13 2in1 previous version was Y part.
FreckledTrout - Wednesday, May 29, 2019 - linkA decent improvement on the graphics front however just barely beating AMD's 3700U isn't that impressive. I mean we are talking a die shrink so there is a lot more die space to play with and graphics should scale out nicely with more graphics cores. AMD's first 7nm mobile chip to replace the 3700U should surpass this 10nm chip rather quickly.
