Falcon 3 10B Instruct on L40S 48GB: 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 L40S 48GB. Every figure is computed by tokcalc's open-source capacity model.

What changes as you add L40S 48GBs
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 L40S 48GB?

Yes. Falcon 3 10B Instruct at FP16 needs 30.7 GB including the KV cache, and L40S 48GB has 48 GB — so it fits on a single GPU.

How fast is Falcon 3 10B Instruct on L40S 48GB?

28.08 tokens/sec per stream and 337.0 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 3.64 s, and inter-token latency is 35.6 ms.

What does Falcon 3 10B Instruct on L40S 48GB cost per million tokens?

$0.5771 per 1M output tokens at 1× L40S 48GB ($0.7000/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 L40S 48GB?

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 L40S 48GB the right choice for Falcon 3 10B Instruct?

It works. Compare $0.5771 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.
