ZYFA Kernels Double FP8 Attention Speed on AMD MI355X
AMD's FP8 attention path has lagged NVIDIA's, partly because the MI355X lacks hardware tracking of matrix instruction completion, making software scheduling critical. ZYFA shows that careful kernel design can close much of that gap, and its open-source release gives engineers a drop-in option for MI355X prefill workloads. Teams benchmarking AMD accelerators against H100 or B200 deployments, including those running DeepSeek-style MLA, should test it against their current AITER setup.
