The completely different software stack is a killer. It’s not that you can’t find versions of a model to run, but almost everything that hits the GPU for compute is going to be targeting CUDA, not RocM. From a compatibility standpoint alone this killed AMD for me. I just do not want to spend my time fighting the stack to get these models running.
Yeah, it’s not that I like this state of affairs, but right now the vendor lock-in is so one-sided that it’s hard to say there’s a viable alternative to CUDA. I hope that changes one day.
