**Yes, but it is tight.** Mistral Small 24B at Q8\_0 needs about 30.3 GB, and the GeForce RTX 5090 has 32.0 GB usable at a \~4k context.

# Can I run Mistral Small 24B on an RTX 5090?

Mistral Small 24B at Q8\_0 needs about 30.3 GB, and the GeForce RTX 5090 has 32.0 GB usable. That figure is 32 GB of VRAM on the spec sheet, of which 32.0 GB is usable for weights and cache, at 1792 GB/s memory bandwidth. Mistral’s 24B Small instruct model, a dense mid-size alternative to the 27B–32B class. These are estimates from [our formula](https://whatcanirunai.vercel.app/method/), not measured benchmarks.

## Memory at each quant

| Quant    | Need vs 32.0 GB | Verdict       |
| -------- | --------------- | ------------- |
| Q4\_K\_M | 17.7 GB         | Q4Fits        |

| FP16     | 56.2 GB         | FP16Won’t fit |

## Estimated tokens per second

Estimate: **42–60 tokens/sec** at Q8\_0\. This is a bandwidth-derived range, not a bench. Efficiency is a 60–85% GPU band from [How we calculate](https://whatcanirunai.vercel.app/method/).

## Context headroom

At Q8\_0, this machine has headroom out to about **8k tokens** under our KV estimate. Longer chats need more memory for the cache. Figures assume an FP16 KV cache.

## What to do instead

* Run [gpt-oss-20b](https://whatcanirunai.vercel.app/can-i-run/gpt-oss-20b/rtx-5090/) instead (15.6 GB at Q4). It is a different model, not a drop-in, but it does fit this machine.
* Keep context short, close other GPU work, and avoid a higher quant. The [VRAM calculator](https://whatcanirunai.vercel.app/vram-calculator/) shows how the KV cache grows.
