Frequently asked questions

Can Gemma 2 9B run on H200 SXM5 141GB?

Yes. Gemma 2 9B at FP16 needs 40.5 GB including the KV cache, and H200 SXM5 141GB has 141 GB — so it fits on a single GPU.

How fast is Gemma 2 9B on H200 SXM5 141GB?

173.3 tokens/sec per stream and 2080 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 333.7 ms, and inter-token latency is 5.8 ms.

What does Gemma 2 9B on H200 SXM5 141GB cost per million tokens?

$0.5342 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 Gemma 2 9B need on H200 SXM5 141GB?

18.0 GB for the weights at FP16, plus 22.5 GB of KV cache for 8 concurrent requests at 8K context — 40.5 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is H200 SXM5 141GB the right choice for Gemma 2 9B?

It works. Compare $0.5342 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 3080 10GB at $0.0248, and the fastest is 8× RTX 3080 10GB at 17916 tok/s.
