A few days back, Intel slipped once again (involuntarily?), confirming the specifications of its Xe-HPG or DG2 graphics cards slated to launch in the coming months. We already had an idea about the core specifications such as the core count, memory, and bus width. Intel has basically gone ahead and confirmed those details. It looks like the company is planning five different SKUs for both the desktop and mobile markets.
The top-end model as already reported will pack 512 Execution Units or 4,096 ALUs (cores). This GPU will likely be paired with a 256-bit bus with up to 16GB of GDDR6 memory. While the mobile variant will feature slightly slower chips, the desktop models are going to be paired with GDDR6 16Gbps memory.
Intel is prepping two chips, one on the BGA1379 and the other on the BGA2660 package. The former will include two SKUs, one with 128 EUs or 1,024 ALUs while the other with 96 EUs or 768 shaders. Both these GPUs will be paired with 4GB GDDR6 memory and a 64-bit bus.

The larger die based on the BGA2660 package will feature three GPUs with 256EU/2048ALU, 384EU/3072ALU, and 512EU/4096ALU configurations. The former will be paired with a 128-bit bus and 8GB of GDDR6 memory while the latter will feature a 256-bit bus paired with 16GB of GDDR6 (16Gbps) memory. The SKU in the middle, on the other hand, will come with 12GB of GDDR6 (14Gbps) memory and a bus width of 192-bits.
It’s highly likely that the SKU1 with 512 EUs will go up against the RTX 3060 Ti or in some cases perhaps even the RTX 3070 while the SKU2 with 384 EUs will compete with the RTX 3060. The final performance will depend on the drivers, API, and the game itself, with the ray-tracing performance expected to be on par with AMD’s RDNA 2 parts, and a notch below NVIDIA’s Ampere offerings.
