Igor’s Lab has shared the specifications for Intel’s upcoming family of Xe-HPG “DG2” GPUs. There are a total of five SKUs, the most powerful of which features 512 Execution Units (4,096 cores), a base/boost clock of 1.1/1.8 GHz, 16 GB of GDDR6 memory, and a TDP of 100 watts. Intel’s Xe-HPG DG2 GPUs will debut first in notebook products; it isn’t clear when the desktop variants are set to arrive.

[…] Intel is planning to use Alder Lake-P in the notebook sector, i.e. CPUs as 1-chip BGA with a TDP of 15 to 45 watts. The production of DG2 for the mobile sector is supposed to start already in calendar weeks 43 to 50 with the two smaller SKUs (4 and 5), if the current plans go, so that one is probably aiming at still very close to the Christmas business. The major SKUs (1 to 3) should then follow between week 50 in 2021 and week 10 in 2022.
