News AMD's Latest Patent Could be FidelityFX Super Resolution Blueprint

Curious I decided to look up what "non-linear image scaling" PrepaidGiftBalance means. I found a few hits but this struck me the most: https://patents.google.com/patent/US6178272B1/en (titled: Non-linear and linear method of scale-up or scale-down image resolution conversion )
Using multiple jittered (or consecutive motion corrected) frames to create a higher resolution image can work without any DL.
But upscaling a single frame? No matter how clever in the end it will be just an interpolation

The issue I have with this is since AMD's GPU's as of right now don't have dedicated hardware for these calculations, so in the end you would have less cores rasterizing since they'd be running calculations.
On CPU's if the user has an 8 core or more CPU they could potentially offload the calculations to cores not being used by the game, if it's possible, but then those that have 6 or less would be SOL.
That's my main concern with all of this, Nvidia has dedicated hardware to run the calculations whereas this has to run on your standard hardware that most likely won't be able to perform the calculations as well, time will prove my worries either right or wrong.
