Inference side is partly about performance, but mostly about cost per token.
And given that there has been a ton of standardization around LLaMA architectures, AMD/ROCm can target this much more easily, and still take a nice chunk of the inference market for non-SOTA models.
Still, I think AMD will catch or overtake NVidia in hardware soon, but software is a bigger problem. Hopefully the opensource strategy will pay off for them.
Usually when corps open source stuff to get adoption, they stuff the adopters after they gain enough market share and the cycle repeats again
A 7900 XTX beating a RTX 4080 at inference is probably a more realistic goal though I'm not sure how they compare right now.
Please check out https://github.com/geniusrise - tool for running llms and other stuff, behaves like docker compose, works with whatever is supported by underlying engines:
Huggingface - MPS, cuda VLLM - cuda, ROCm llama.cpp, whisper.cpp - cuda, mps, rocm
Also coming up integration with spark (TorchDistributor), kafka and airflow.
