I wonder how many use cases will be impacted. I can imagine specific use cases like video encoding switching to the built-in co-processors. Which part of usage remains that is hampered by this? Is there a killer reason/use case I should stick to amd? Also, it would probably be relatively trivial to add the 256bit instructions in the next iteration of the chip.
