Q: How fast is mixtral 8x7B MoE on the NVIDIA H100 80GB PCIe?

~240–400 tok/s (active-expert estimate) on the NVIDIA H100 80GB PCIe. computed roofline: 2039 GB/s × 0.46–0.76 efficiency window / 3.9GB (Q4_K_M) — bands, never points. MoE: file is 26GB (that decides fit) but only ~1.05B of experts activate per token (~3.9GB 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 mixtral 8x7B MoE?

Accepted Answer

mixtral 8x7B MoE needs about 26.5GB working set (weights 26GB + KV cache 0.5GB at 4k context). The NVIDIA H100 80GB PCIe offers ~80GB usable — verdict: full. 26.5 GB needed of 80 GB usable — headroom for context
