Intel has started releasing documentation on its upcoming discrete GPU for the desktop segment (Discrete Graphics 2) DG2, based on the Xe-HPG architecture.
Thanks to this new documentation, we can discover some of the most important specifications that Xe-HPG DG2 will offer, which will be used for desktop PCs and laptops, at different levels of performance.
New product documentation is typically hidden on Intel's site, but a simple search for the term “discrete graphics2” has unbelievably revealed dozens of documents about Intel's DG2 family.
What has been discovered, according to the documentation, is that there will be five different models for laptops and two for desktop computers. The notebook GPUs are called SKU1 through SKU5 and the desktop variants are called SoC1 and SoC2.
One of the most important known specifications is that it will have support for PCIe 5.0, which doubles the bandwidth over PCIe 4.0. Intel has decided to use GDDR6 memory which can run at speeds of 14 or 16 Gbps. The use of HDMI 2.1 and DisplayPort Alt Mode ports over USB Type-C is mentioned.
The GPU with the fewest execution units will have 96 UEs and the maximum will have about 512 UEs (128 UE, 256 UE, 384 UE, and 512 UE).
Intel may be planning to reveal more GPU models for desktops (with more UEs, perhaps), as it is strange that there are only two models for that segment and five for laptops. We expect Intel to talk more about the Xe-HPG chips in the coming weeks. We will keep you informed.
