Llama 3 70B on H200 SXM5 141GB: Does It Fit, How Fast, What It Costs

Llama 3 70B at FP8 (E4M3) needs 70.6 GB for its weights and 92.1 GB in total at 8K context with 8 concurrent users. That means it fits on a single H200 SXM5 141GB. Every figure is computed by tokcalc's open-source capacity model.

Frequently asked questions

Can Llama 3 70B run on H200 SXM5 141GB?

Yes. Llama 3 70B at FP8 (E4M3) needs 92.1 GB including the KV cache, and H200 SXM5 141GB has 141 GB — so it fits on a single GPU.

How fast is Llama 3 70B on H200 SXM5 141GB?

66.29 tokens/sec per stream and 795.5 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 2.38 s, and inter-token latency is 15.1 ms.

What does Llama 3 70B on H200 SXM5 141GB cost per million tokens?

$1.40 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 Llama 3 70B need on H200 SXM5 141GB?

70.6 GB for the weights at FP8 (E4M3), plus 21.5 GB of KV cache for 8 concurrent requests at 8K context — 92.1 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is H200 SXM5 141GB the right choice for Llama 3 70B?

It works. Compare $1.40 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 4080 16GB at $0.1031, and the fastest is 4× Cerebras CS-3 (WSE-3) at 45076 tok/s.
