Can I run R1 Distill 32B on an RTX 5080?
R1 Distill 32B at Q4_K_M needs about 23.8 GB, and the GeForce RTX 5080 has 16.0 GB usable. That figure is 16 GB of VRAM on the spec sheet, of which 16.0 GB is usable for weights and cache, at 960 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, not measured benchmarks.

Memory at each quant
| Quant | Need vs 16.0 GB | Verdict |
|---|---|---|
| Q4_K_M | 23.8 GB | Q4Won’t fit |
| Q8_0 | 41.0 GB | Q8Won’t fit |
| FP16 | 76.4 GB | FP16Won’t fit |
Estimated tokens per second
No speed estimate: R1 Distill 32B does not fit in the 16.0 GB this machine can use, so we do not publish a tokens/sec figure for CPU offload.
Context headroom
Even at a short ~4k context, the weights do not fit. Extending context would only increase the gap.
| Context | KV cache (FP16) | Total at Q4_K_M | Verdict |
|---|---|---|---|
| 4k | 1.1 GB | 23.8 GB | Won’t fit |
| 8k | 2.1 GB | 24.9 GB | Won’t fit |
| 16k | 4.3 GB | 27.1 GB | Won’t fit |
| 32k | 8.6 GB | 31.4 GB | Won’t fit |
| 64k | 17.2 GB | 39.9 GB | Won’t fit |
| 128k | 34.4 GB | 57.1 GB | Won’t fit |
What to do instead
- Run gpt-oss-20b instead (15.6 GB at Q4). It is a different model, not a drop-in, but it does fit this machine.
- To hold R1 Distill 32B at Q4, you need about 23.8 GB. The GeForce RTX 3090 has 24.0 GB usable ($1499 list price).
- CPU offload can load the weights anyway, but it is slow. We do not publish an offload tokens/sec figure.

Quick answers
- Can I run R1 Distill 32B on an RTX 5080?
- No. R1 Distill 32B at Q4_K_M needs about 23.8 GB, and the GeForce RTX 5080 has 16.0 GB usable.
- How much VRAM does R1 Distill 32B need?
- About 23.8 GB at Q4_K_M, 41.0 GB at Q8_0 and 76.4 GB at FP16, estimated for a ~4k context.
- How fast is R1 Distill 32B on an RTX 5080?
- We do not estimate tokens/sec when the model does not fit. CPU offload is possible but slow.
- What context length can I use?
- The weights already do not fit, so longer context is not the limiting factor.
