Ask HN: Why hasn’t AMD made a viable CUDA alternative?

I appreciate developing ROCm into something competitive with CUDA would require a lot of work, both internally within AMD and with external contributions to the relevant open source libraries.

However the amount of resources at stake is incredible. The delta between NVIDIA's value and AMD's is bigger than the annual GDP of Spain. Even if they needed to hire a few thousand engineers at a few million in comp each, it'd still be a good investment.

I can't contribute much to this discussion due to bias and NDAs, but I just wanted to mention, technically HIP is our CUDA competitor. ROCm is the foundation that HIP is being built on.

So if someone would like to, say, port a CUDA codebase to AMD, you would use HIP for a more or less 1-on-1 translation?

Any card you would recommend, when trying to replace the equivalent of a 3090/4090?

I can't recommend cards, but you are absolutely correct about porting CUDA to HIP: there was (is?) a hipify program in rocm that does most of the work.
