Frequently asked questions

Can the RTX 3090 run DeepSeek R1 Distill Qwen 32B?
The model needs about 22.4 GB and fits in the 23.3 GB available (0.9 GB left).
Which quantization should I use on the RTX 3090?
Q4_K_M is the highest-precision quantization that fits entirely in VRAM at 8K context. ~22.4 GB / 23.3 GB.
What is the largest context on the RTX 3090?
At Q4_K_M, about 11K tokens fit entirely in VRAM with an f16 KV cache. A q8_0 KV cache roughly doubles that.
How fast is DeepSeek R1 Distill Qwen 32B (RTX 3090)?
We estimate 31–42 tok/s (estimate, confidence low). Based on: memory bandwidth (936 GB/s) and model size.
