What changes as you add RTX 4090 24GBs
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 Mistral 7B v0.3 run on RTX 4090 24GB?

Yes. Mistral 7B v0.3 at FP16 needs 23.1 GB including the KV cache, and RTX 4090 24GB has 24 GB — so it fits on a single GPU.

How fast is Mistral 7B v0.3 on RTX 4090 24GB?

45.25 tokens/sec per stream and 543.0 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 2.92 s, and inter-token latency is 22.1 ms.

What does Mistral 7B v0.3 on RTX 4090 24GB cost per million tokens?

$0.2046 per 1M output tokens at 1× RTX 4090 24GB ($0.4000/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Mistral 7B v0.3 need on RTX 4090 24GB?

14.5 GB for the weights at FP16, plus 8.6 GB of KV cache for 8 concurrent requests at 8K context — 23.1 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is RTX 4090 24GB the right choice for Mistral 7B v0.3?

It works. Compare $0.2046 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 4× RTX 3080 10GB at $0.0399, and the fastest is 1× Cerebras CS-3 (WSE-3) at 10773 tok/s.
