Intel’s DG2 GPU Leaked Specifications Show Serious Potential

Intel’s Iris Xe DG1 may be shaping up to be a disappointment, but the chipmaker’s approaching Xe-HPG DG2 GPU could be a solid performer. German publication Igor’s Lab has shared the alleged specifications for the DG2 in its desktop and mobile format.

The Xe-HPG DG2 block diagram seemingly suggests that Intel had originally planned to pair the GPU with its Tiger Lake-H chips, which are rumored to launch next week. It would seem that Intel didn’t make the window for Tiger Lake-H, however, as Wallossek claims that the chipmaker will use the DG2 for Alder Lake-P instead. The DG2 reportedly features the BGA2660 package.

Apparently, the DG2 was supposed to communicate with Tiger Lake-H through a high-speed PCIe Gen 4.0 x12 interface. The 12-lane connection is a bit unorthodox, so it’s uncertain if that was a typo. The DG2 would be the first GPU to offer DisplayPort 2.0 support. Oddly, the GPU only supports HDMI 2.0 and not HDMI 2.1. However, Wallossek did mention that this was an outdated diagram and DG2 could perhaps come with HDMI 2.1.

Wallossek shared a drawing of the board layout for a Tiger Lake-H chip that’s accompanied by the DG2. We spotted a total of six memory chips. Evidently, only two of the memory chips are actually attached to the DG2. This would mean that the remaining four memory chips are probably soldered memory chips for the system.
