Nvidia versus AMD Disagg Prefill

With today’s release of InferenceXv2, for the first time the ML community is able to see a full Pareto frontier for open-source MI355X distributed inference. We show Pareto curves for the B200 and MI355X with and without enabling MTP.

Evidence

For FP8 disagg prefill, MI355X (MoRI SGLang) is quite competitive with B200 (Dynamo SGLang)
