Intel's Raja Koduri shows off the Xe-HPG DG2 512 EU GPU, hints at possible support for AMD FSR aside from Xe-HPG's own deep learning tech
We have previously reported about Intel Xe-HPG DG2 including the possible executing unit (EU) counts, likely TDP, PCIe links, etc. Now, Intel's graphics chief Raja Koduri showed off the first fully ready Xe-HPG DG2 silicon.
Taking to Twitter, Raja called the Xe-HPG DG2 "real candy". Going by the markings on the die, this particular GPU appears to be a 512 EU part. In the words of Intel graphics VP Roger Chandler, Xe-HPG DG2 has progressed "from jittery journeys to buttery smooth". Raja said that it's now time for Intel graphics software engineering led by Lisa Pearce to do "lots of game and driver optimization work".
AMD introduced its FidelityFX Super Resolution (FSR) upscaling technique during its Computex 2021 keynote yesterday as an open architecture that can run on almost all modern GPUs including ones from NVIDIA. FSR supports DirectX 12, DirectX 11, and Vulkan titles, so it is only natural to expect that it would eventually work on the Xe-HPG as well.
To a query as to whether Intel would also get onboard, Raja said that Intel is "definitely looking at it". He also said that the deep learning capabilities of Xe-HPG can achieve "better quality and performance", but Intel will try to "align with open approaches to make ISV's job easier".
While we know Xe-HPG DG2 will support hardware accelerated ray tracing, we've also heard rumors that Intel may introduce its own supersampler probably called XeSS. It is likely that Raja was referring to XeSS when he said that Xe-HPG's deep learning can achieve "better quality and performance". In any case, supporting open standards such as FSR will definitely be welcomed by developers.
Xe-HPG (DG2) real candy - very productive time at the Folsom lab couple of weeks ago. “From jittery journeys to buttery smooth” said @rogerdchandler -— Raja Koduri (@Rajaontheedge) June 2, 2021
lots of game and driver optimization work ahead for @gfxlisa’s software team. They are all very excited..and a little scared:) pic.twitter.com/tQcfEWf8p4
Definitely looking at it - the DL capabilities of Xe HPG architecture do lend to approaches that achieve better quality and performance. We will definitely try to align with open approaches to make ISVs job easier..— Raja Koduri (@Rajaontheedge) June 2, 2021
