Context Before

Blackwell Ultra GB300 added 50% more dense FP4 while

Evidence

keeping sparse FP4 FLOPs the same, while AMD’s MI355X stopped supporting structured sparsity on MXFP8, MXFP6

Context After

and MXFP4 formats to save silicon area.

② Atomic Claim

……sparse FP4 FLOPs 維持不變；另一方面，AMD 的 MI355X 已停止在 MXFP8 與 MXFP6 上支援 structured sparsity……
