**Yes.** R1 Distill 32B at Q4\_K\_M needs about 23.8 GB, and the GeForce RTX 5090 has 32.0 GB usable at a \~4k context.

# Can I run R1 Distill 32B on an RTX 5090?

R1 Distill 32B at Q4\_K\_M needs about 23.8 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. A 32B DeepSeek-R1 distill on Qwen. Memory need matches Qwen3-32B; the weights are distilled from DeepSeek-R1\. 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 | 23.8 GB         | Q4Fits        |
| Q8\_0    | 41.0 GB         | Q8Won’t fit   |
| FP16     | 76.4 GB         | FP16Won’t fit |

## Estimated tokens per second

Estimate: **54–77 tokens/sec** at Q4\_K\_M. 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 Q4\_K\_M, this machine has headroom out to about **32k tokens** under our KV estimate. Longer chats need more memory for the cache. Figures assume an FP16 KV cache.
