Frequently asked questions

Can Qwen 3 32B run on H200 SXM5 141GB?

Yes. Qwen 3 32B at FP8 (E4M3) needs 49.2 GB including the KV cache, and H200 SXM5 141GB has 141 GB — so it fits on a single GPU.

How fast is Qwen 3 32B on H200 SXM5 141GB?

146.3 tokens/sec per stream and 1755 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 1.10 s, and inter-token latency is 6.8 ms.

What does Qwen 3 32B on H200 SXM5 141GB cost per million tokens?

$0.6331 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 Qwen 3 32B need on H200 SXM5 141GB?

32.0 GB for the weights at FP8 (E4M3), plus 17.2 GB of KV cache for 8 concurrent requests at 8K context — 49.2 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is H200 SXM5 141GB the right choice for Qwen 3 32B?

It works. Compare $0.6331 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 3080 10GB at $0.0294, and the fastest is 2× Cerebras CS-3 (WSE-3) at 24863 tok/s.
