Context Before

NVIDIA is offering sparsity for FP4, marketing 50 PFLOPS of FP4, while

Evidence

AMD has opted to remove sparsity support since CDNA4 for inference dtypes.

Context After

Harnessing the 50 PFLOPS sparse vs 35 PFLOPS dense drops the cost per perf in units of $/hr per Marketed PFLOP by 35%—a valid comparison if AI Labs can indeed successfully harness Sparse FP4 on the VR NVL72.

② Atomic Claim

AMD 自 CDNA4 起，已選擇在 inference dtypes 移除 sparsity support。
