First leaked pictures and specs for Intel's Arctic Sound (Xe-HP) compute GPUs emerge
Along with the upcoming DG2 gaming GPUs also known as Xe-HPG, Intel is planning to release its first compute accelerators for the HPC market. From previous roadmaps, we already know that these compute accelerators codenamed Arctic Sound (Xe-HP) will be based on the same processors integrated in the Xe-HPG models, but will feature a tile-based approach that combines up to four chips into one to maximize performance. Thanks to a fresh leak from Igor’s LAB, we now have more detailed specs for the 1-tile and 2-tile configurations, plus a couple of pics showing the boards with their cooling systems.
Since the Xe-HPG and Xe-HP share the same GPU architecture, the maximum number of execution units (EUs) per tile is known to be set at 512, Now, the high-end gaming cards will only feature one tile with all 512 EUs activated, but the compute versions will have slightly different EU configurations. The 1-tile compute accelerator codenamed Arctic Sound 1T is only getting 384 EUs enabled on its single tile, which translates to 3072 shading units, plus it features 16 GB of HBM2e video memory, and it also gets a lower TGP of 150 W compared to the 225 W rating for the high-end 512 EU gaming models. The dual-tile version known as Arctic Sount 2T ups the number of activated EUs per tile to 480, so it effectively gets 7680 shading units, and it also packs 32 GB of HBM2e VRAM, with the TGP rating being bumped to 300 W. Both cards integrate a PCIe 4.0 link, yet the 2T model appears to feature a special cage and there is no standard motherboard connector. It is also considerably longer and thicker, occupying 2 slots, plus it comes with an 8-pin power connector.
Apparently, the quad-tile version might have some production issues and is not currently tested in Intel’s labs. Igor mentions that the info for the 1T and 2T versions comes straight from Intel’s internal slides.
