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. 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. Whether actual GEMM performance reaches 50 PFLOPS depends on how many zeros are in the tensor. The more zeros, the closer it can reach. The less zeros in the tensor, the lower the speedup. Overall, we expect to see much greater traction for Rubin’s adaptive sparsity compression as opposed to structured sparsity thanks to the automatic implementation.

With that said, many ML Systems engineer are still skeptical that this new form of sparsity will work well, and it is very possible that Nvidia’s 50 PFLOPS is purely marketing like prior generations

Evidence

Supply chain rumors have indicated that there are 2 different “SKUs” with different power and performance profiles: a Max-P variant at 2,300W and a Max-Q variant at 1,800W

Context After

These power profiles are software managed. Users can also choose whatever max power draw they prefer (as long as it is no more than 2,300W per GPU) and this has been the case for previous GPU generations as well. Several hyperscalers and labs have chosen to run their GPUs at lower power to optimize for performance per Watt as well as taking into account power availability constraints.
