Context Before

This means the sparser the workload, the closer the performance will be to the 50 PFLOPS marketed peak performance. NVIDIA thus brands the 50 PFLOPS figure as FP4 Inference while the 35 PFLOPS FP4 Training number is for dense workloads.

Evidence

As accuracy is preserved, this allows the marketing team to claim 5x FLOPs for Rubin over GB200, comparing 50 PFLOPS dynamically compressed FP4 to 10 PFLOPS dense FP4.

Context After

Whether actual GEMM performance reaches 50 PFLOPS depends on how many zeros are in the tensor.

② Atomic Claim

在維持 accuracy 的前提下，marketing team 可宣稱 Rubin 的 FLOPs 是 GB200 的 5 倍：比較 50 PFLOPS 的 dynamically compressed FP4 與 10 PFLOPS 的 dense FP4。
