Intel’s XeSS is agnostic, but is it asymmetric?

At Intel’s Architecture Day in August 2021, the company announced it would include with the forthcoming GPU an AI-based upscaling capability called XeSS that was similar to Nvidia’s DLSS. Not only that, but it would be GPU agnostic and run on AMD and Nvidia GPUs.  XeSS is a temporal (using information from the current and past frames) upscaling algorithm designed to run games at a lower resolution before scaling them up to a higher resolution.  XeSS uses recent frame data to estimate current frames.
