Intel Xe UHD 750 and UHD 730: integrated GPU in Rocket Lake

Intel has already revealed a lot about the Rocket Lake processors, and a lot has escaped. But there wasn’t much to his new integrated GPU Xe. It will exist in two variants and we have the first benchmarks, according to which the version of the UHD 750 could be half as fast as the graphics that Intel now has in Comet Lake.

Leaks of unreleased graphics cards are our favorite topic, but not very often in this spirit it gets to Intel’s integrated graphics. It seems that now comes the first look at the integrated GPU in interesting Intel Rocket Lake processors – chips, which, although still 14nm, will bring a new CPU architecture in Intel’s desktop for the first time since 2015, but also GPUs. Rocket Lake uses it architecture Xe LP (or also Gen12 LP) from 10nm Tiger Lake processors.

A leaker appeared on the Bilibili Chinese forum, which acquired a Rocket Lake processor somewhere, specifically the Core i5-11500 model. This is far from the first Rocket Lake escape, a few days ago it even appeared first preliminary review with extensive performance tests of the Core i7-11700K (which is a very interesting read, but beware, this is an EC sample and the performance may not be final). But all these leaks only focus on CPU performance, the integrated graphics are out of the spotlight. But the escape to Bilibili showed more about her, and since these are perhaps the first details, let’s take a closer look.

Rocket Lake graphics: Xe or just UHD?

Although the processor has an Xe architecture, it is not entirely clear whether Intel’s iGPU will be given the more verbal name Iris Xe. In Windows Device Manager, the Core i5-11500 graphics are detected as Intel Iris Xe, but elsewhere the designation is UHD 750 (Ultra HD Graphics 750), similar to the old integrated graphics in Skylake to Comet Lake. It is possible that this inconsistency reflects immature drivers, and Intel is still reconciling.

There will be two configurations of integrated graphics in Rocket Lake – perhaps marked (Xe?) UHD 750 and UHD 730. Version UHD 750 should be fully active with 32 EU (256 shaders). But there will also be a trimmed variant, UHD 730 where only 24 EU (192 shaders) will be active. This is probably to use chips where there is a defect in the GPU.

At first glance, it’s a bit striking, but the Core i5-11500 (65W locked six-core) will have a higher configuration with 256 shaders / 32 EU, UHD 750, although it is a processor in the menu occupying a low space. According to the Romanian website lab501, which published the above-mentioned pre-review, a weaker variant of the UHD 730 with only 24 EU will be present only in the six-core Core i5-11400 processor, which will be even cheaper than the i5-11500 that the Chinese leaker had. All other Rocket Lake processors will already have a UHD 750.

Unfortunately, the GPU-Z cannot properly detect these graphics, so we do not know what the frequency is (it would be interesting to compare it with the 10nm GPU Iris Xe clock speed).

Leaker showed the FPS that this graphic (Xe?) UHD 750 achieves in a few less demanding games, you can see some images in the gallery below. However, the performance may not be adequate, as tightened drivers could increase it even more.

V 3DMarku Time Spy gained a UHD 750 with current drivers 1053 points, while a standard UHD 630 in a Core i5-10400 processor (six-core Comet Lake, 24 EU) reached 693 points. So the new graphics in Rocket Lake would be more than 50% more powerful.

The score from was also shown Chinese benchmark Ludashi (or perhaps Master Lu). If I’m not mistaken, the graphics performance could perhaps represent the second of a series of four numbers in the screenshots – the Core i5-11500 got 26,116 points, while the old Core i5-10400 model only 14,927 points. According to this, Rocket Lake graphics would have 45% more 3D performance than the one in Comet Lake.

GPU performance will not be paramount

In any case, the game performance of integrated graphics will probably not be the main thing that most users will be interested in on Rocket Lake. Of course, CPU performance will be more important; The integrated GPU will probably serve mainly as a display. In this role, it will be important that HDMI 2.0 is finally to be supported, enabling the connection of 4K monitors with a 60Hz frame rate. With DisplayPort, the resolution that the graphics can handle could also increase. And these 14nm Xe UHD 750 and 730 graphics will also support hardware video playback in AV1 format (perhaps up to 8K resolution).
