I already suggested ROCm to Cedric along with a load of other things
A big one is Unsplash integration - makes getting test images dead easy (I’m planning to do this for my CLI GUI)
ROCm would potentially allow AMD GPUs to be used (but I ain’t got an AMD GPU to test on so no way to try it). MKL also looks promising. This means that possibly modern non-M1 Macs could get GPU boost (M1 is something I’ve yet to consider - dunno if TF will bother and ain’t got an M1 either)
