Following confirmation from an Intel representative that Xe-HPG DG2 graphics cards are “just around the corner,” specifications for five different cards on mobile devices and possibly desktops have been leaked courtesy of Igor’s Lab.
The leak confirms previous rumors that the flagship DG2 series will contain 512 EUs (execution units) and 16 GB of GDDR6 video memory on a 256-bit bus. However, this card – provisionally called DG2-512EU – is not suitable for the desktop. Intel is reportedly focused on the cellular market and DG2 chips were originally planned as part of the Tiger Lake-H platform, which appears to be launching next week.
Previous rumors have said that Intel will be using the same design for additional desktop cards, but the DG2-512EU and two other scaled-down variants are expected to be launched later this year along with Alder Lake-P’s mobile chips.

The DG2-512EU is based on the BGA2660 package and is the largest and most powerful of the three chips that use the same package. In addition to 512 EUs and 16 GB VRAM, the DG2-512EU has a base clock of 1.1 GHz and a boost clock of 1.8 GHz, 16 MB cache and a TDP of 100 W. This includes the DG2-384EU 384 EUs, 12 GB VRAM and a base clock of 600 MHz (although otherwise identical specifications). Finally, there is the DG2-256EU with 256 EUs, 8 GB VRAM and a boost clock of 1.4 GHz.
There are two SKUs among the three based on the BGA2660 package, but it’s not clear whether they are aimed at the mobile or desktop crowd. The top option in this subsection is 196 EUs and 4 GB of VRAM on a 64-bit bus. Underneath is an identical card, except that it has 128 EUs. These models are clearly aimed at beginners.
The performance requirements show that Intel is focusing on mobile devices first, as the top three chips have a TDP of 100 watts, which is the same as Nvidia’s RTX 30 series mobile chips.
Intel XE DG2 graphics offer hardware-accelerated ray tracing and supersampling technology similar to that of Nvidia DLSS. Current rumors assume that the midrange models will cost between $ 200 and $ 300 and appear in late 2021. However, given the global semiconductor shortage, the cards could cost more and take longer to be released.
