Frequently asked questions

Can Mixtral 8x7B (MoE) run on H200 SXM5 141GB?

Yes. Mixtral 8x7B (MoE) at FP8 (E4M3) needs 55.3 GB including the KV cache, and H200 SXM5 141GB has 141 GB — so it fits on a single GPU.

How fast is Mixtral 8x7B (MoE) on H200 SXM5 141GB?

362.8 tokens/sec per stream and 4353 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 459.7 ms, and inter-token latency is 2.8 ms.

What does Mixtral 8x7B (MoE) on H200 SXM5 141GB cost per million tokens?

$0.2552 per 1M output tokens at 1× H200 SXM5 141GB ($4.00/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Mixtral 8x7B (MoE) need on H200 SXM5 141GB?

46.7 GB for the weights at FP8 (E4M3), plus 8.6 GB of KV cache for 8 concurrent requests at 8K context — 55.3 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is H200 SXM5 141GB the right choice for Mixtral 8x7B (MoE)?

It works. Compare $0.2552 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 3080 10GB at $0.0119, and the fastest is 2× Cerebras CS-3 (WSE-3) at 61674 tok/s.
