beffjezos··on GLM5.2 on AMD MI355X at 2626 tok/s/node at over 2x lower cost than Blackwell
Yeah that makes sense. I'm more familiar with seeing tok/s/user + TTFT rather than the total node throughput.
beffjezos··on Performance per dollar is getting faster and cheaper
Oh, that's much better then. A good metric to share is the tokens per second per user for the node rather than the total throughput of the node. It disambiguates what's being optimized for much better than your blog post currently does.

This is very interesting and yet not at the same time. This looks to be optimized for single-stream LLM traffic which is not viable to serve in a production setting. It's only interesting to hobbyists that want to run the model locally.

It's genuinely neat that AI can find the right optimization pathways in an AMD inference server to unlock this but at the same token (pun-intended) this is a classic case of benchmark hacking that doesn't stand up to real-world application.
