Another snippet of information from Intel today relates to the company’s future mobile platform CPU. We know it’s called Ice Lake-U, that it is built on Intel’s 10nm process, that it has Sunny Cove cores, and has beefy Gen11 integrated graphics. We’re still waiting on finer details about where it’s going to be headed, but today Intel is unloading some of its integrated graphics performance data for Ice Lake-U.

It should be noted that this data is performed by Intel, and we have had no ability to verify it in any way. Intel shared this information with a number of press in order to set a level of expectations. We’ve been told that this is Intel’s first 1 TeraFLOP graphics implementation, and it performs as such. The presentation was given by Ryan Shrout, ex owner and editor-in-chief of PC Perspective, and data was performed by his team inside Intel.

Ryan first showed us a direct comparison between the Gen9 graphics found in Intel’s latest and best Whiskey Lake platform at 15W up against a 15W Ice Lake-U product. The results make for pleasant reading. In the game demo scenes that Intel showed us, we saw upwards of a 40% gain in performance in average frame rates. Percentile numbers were not shown.

When comparing to an equivalent AMD product, Intel stated that it was almost impossible to find one of AMD’s latest 15W APUs actually running at 15W in a device – they stated that every device they could find was actually running one of AMD’s higher performance modes. To make the test fair, Intel pushed one of its Ice Lake-U processors to the equivalent of a 25W TDP and did a direct comparison. This is essentially AMD’s Vega 10 vs Intel’s Gen 11.

For all the games in Intel’s test methodology, they scored anywhere from a 6% loss to a 16% gain, with the average somewhere around a 4-5% gain. The goal here is to show that Intel can focus on graphics and gaming performance in ultra-light designs, with the aim to provide a smooth 1080p experience with popular eSports titles.

Update: As our readers were quick to pick up on from Intel's full press release, Intel is using faster LPDDR4X on their Ice Lake-U system. This is something that was not disclosed directly by Intel during their pre-Computex presentation.

For some background context, LPDDR4X support is new to Ice Lake-U, and long overdue from Intel as a consequence of Intel's 10nm & Cannon Lake woes. It offers significant density and even greater bandwidth improvements over LPDDR3. Most 7/8/9th Gen Core U systems implemented LPDDR3 for power reasons, and OEMs have been chomping at the bit for LPDDR4(X) so that they don't have to trade off between capacity and power consumption.

That Intel used LPDDR4X in Ice Lake-U versus DDR4 in the AMD system means that Intel had a significant memory bandwidth and latency advantage – around 56%, on paper at least. This sort of differential matters most in integrated graphics performance, suggesting that this is one angle that Intel will readily leverage when it comes to comparisons between the two products.

Moving on, the last set of data comes from Intel’s implementation of Variable Rate Shading (VRS), which was recently introduced in DirectX 12. VRS is a technique that allows the game developer to change the shading resolution of an area on the screen on the fly, allowing a developer to reduce the amount of pixel shading used in order to boost performance, and ideally doing this with little-to-no impact in image quality. It is a new supported feature on Gen11, but it does require the game to support the feature as well. The feature is game specific, and the settings are tuned by the game, not the driver or GPU.

Intel showed that in an ideal synthetic test, they scored a 40% uplift with VRS enabled, and in the synthetic test comparing VRS on and off, that extra performance put it above an equivalent AMD Ryzen system. AMD’s GPU does not support this feature at this time.

Intel is also keen to promote Ice Lake as an AI CPU, due to its AVX512 implementation, and any software than can take advantage of AI can be equipped with accelerated algorithms to speed it up.

We expect to hear more about Ice Lake this week at Computex, given Intel’s keynote on Tuesday, but we also expect to see some vendors showing off their Ice Lake-U designs.

    "This coupled with their atrocious coverage of that ridiculous "security research" team trying to trash AMD makes Anandtech look really bad."

    Do you mean CTS-Labs? Where Ian basically poked several large holes in their story when he interviewed them?

    Because it not real news - who cares about this bs. Show me a real example of it. Reply

    Keep in mind this is IceLake - it has most of if not all migrations in hardware. End of story. Reply

    HStewart,

    keep in mind.. this is intel published benchmarks, and as such.. should be taken as cherry picked and taken with loads of salt, and considered as false and just a PR move by intel

    "Might as well ask how much Intel paid them to put up an article and a pipeline story on a Sunday"

    This is part of our regular Computex coverage. Taiwan is 12 hours ahead of the US east coast, and vendors are already rolling out announcements on Sunday because there's so much going on the rest of the week.

    "so my guess is that this is paid for content by Intel the day before AMD has a reveal event"

    If it were paid content (and I wouldn't approve of something like this), then it would be made very clear in the article that it was a sponsored news post.

    Keep in mind, not only 12 hour time difference but also that tomorrow is not consider a holiday in Taiwan. So it is business as usual. Reply

    "May I ask Why AnandTech hasn't covered or mention, even in the news pipeline about Zombieload or MDS?"

    Backlogged on testing. I'm in the middle of something, but I ran out of time before Computex.

    I don't want to put up an article without data; there's too many misconceptions and wishcasting on the subject, which is leading to everyone losing their minds.

    Thx for the reply. I just thought since Intel release an actual statement and CVE, it would be great if Anandtech just mention with a few sentence post, and with further details to come later. Just one or two sentence will do.

    I mostly limited to reading Anandtech as the only tech web site, when I saw there were discussion on twitter a few days after the Zombieload I was suppressed I didn't read about it earlier.
