Falcon 3 10B Instruct on H100 SXM5 80GB: Does It Fit, How Fast, What It Costs

Falcon 3 10B Instruct at FP16 needs 20.0 GB for its weights and 30.7 GB in total at 8K context with 8 concurrent users. That means it fits on a single H100 SXM5 80GB. Every figure is computed by tokcalc's open-source capacity model.

What changes as you add H100 SXM5 80GBs
Tensor-parallel degree vs VRAM, throughput, and cost. Cost scales linearly with GPU count; decode throughput scales near-linearly too, so cost per token stays roughly flat.

Frequently asked questions

Can Falcon 3 10B Instruct run on H100 SXM5 80GB?

Yes. Falcon 3 10B Instruct at FP16 needs 30.7 GB including the KV cache, and H100 SXM5 80GB has 80 GB — so it fits on a single GPU.

How fast is Falcon 3 10B Instruct on H100 SXM5 80GB?

108.9 tokens/sec per stream and 1307 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 370.2 ms, and inter-token latency is 9.2 ms.

What does Falcon 3 10B Instruct on H100 SXM5 80GB cost per million tokens?

$0.5315 per 1M output tokens at 1× H100 SXM5 80GB ($2.50/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Falcon 3 10B Instruct need on H100 SXM5 80GB?

20.0 GB for the weights at FP16, plus 10.7 GB of KV cache for 8 concurrent requests at 8K context — 30.7 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is H100 SXM5 80GB the right choice for Falcon 3 10B Instruct?

It works. Compare $0.5315 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 4× RTX 3080 10GB at $0.0551, and the fastest is 1× Cerebras CS-3 (WSE-3) at 7800 tok/s.
