Falcon 3 10B Instruct on A100 40GB SXM4: 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 A100 40GB SXM4. Every figure is computed by tokcalc's open-source capacity model.

What changes as you add A100 40GB SXM4s
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 A100 40GB SXM4?

Yes. Falcon 3 10B Instruct at FP16 needs 30.7 GB including the KV cache, and A100 40GB SXM4 has 40 GB — so it fits on a single GPU.

How fast is Falcon 3 10B Instruct on A100 40GB SXM4?

50.38 tokens/sec per stream and 604.5 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 1.10 s, and inter-token latency is 19.9 ms.

What does Falcon 3 10B Instruct on A100 40GB SXM4 cost per million tokens?

$0.4136 per 1M output tokens at 1× A100 40GB SXM4 ($0.9000/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 A100 40GB SXM4?

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 A100 40GB SXM4 the right choice for Falcon 3 10B Instruct?

It works. Compare $0.4136 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.
