Frequently asked questions

Can Qwen 2.5 14B run on H200 SXM5 141GB?

Yes. Qwen 2.5 14B at FP16 needs 40.9 GB including the KV cache, and H200 SXM5 141GB has 141 GB — so it fits on a single GPU.

How fast is Qwen 2.5 14B on H200 SXM5 141GB?

111.4 tokens/sec per stream and 1337 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 502.4 ms, and inter-token latency is 9.0 ms.

What does Qwen 2.5 14B on H200 SXM5 141GB cost per million tokens?

$0.8310 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 2.5 14B need on H200 SXM5 141GB?

28.0 GB for the weights at FP16, plus 12.9 GB of KV cache for 8 concurrent requests at 8K context — 40.9 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is H200 SXM5 141GB the right choice for Qwen 2.5 14B?

It works. Compare $0.8310 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 3080 10GB at $0.0386, and the fastest is 8× RTX 3080 10GB at 11517 tok/s.
