Stas Bekman Proposes MSMF: a Sustainable Matmul FLOPS Metric for Real GPU Planning
StasBekman · x · 2026-10-02
Stas Bekman introduces a new performance metric split: MSMF (Maximum Sustainable Matmul FLOPS, the power-saturated sustained rate) vs MAMF (Maximum Achievable, boost-clock burst ceiling). He has already measured 4 NVIDIA and 1 AMD GPUs, with results matching familiar MFU/HFU numbers since they reflect sustainable workloads — arguing budget planning should be grounded in these real figures, measured per cluster.
