Q: How fast is qwen3 30B-A3B MoE on the NVIDIA H100 80GB PCIe?

~500–830 tok/s (active-expert estimate) on the NVIDIA H100 80GB PCIe. computed roofline: 2039 GB/s × 0.46–0.76 efficiency window / 1.9GB (Q4_K_M) — bands, never points. MoE: file is 18.6GB (that decides fit) but only ~3B of experts activate per token (~1.9GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math

Question 1

Can the NVIDIA H100 80GB PCIe run qwen3 30B-A3B MoE?
