Everything AI already runs on x86. Knight's Mill had 72 cores with 244 threads with AVX512, connected to 16gb of 400gb/s local DRAM and up to 384gb of 115gb/s DRAM. Very similar bandwidth to GPUs of the era but with the addition of more DRAM on a second performance tier a little further away from the CPU. AMD's having a ton of success with Epyc and Threadripper putting up very similar numbers. The development story for Knight's Mill was a lot simpler than for any GPU. Consequently, I don't think developers were the ones who needed convincing.
