NVIDIA L40 does not meet the minimum VRAM requirement for Q4 inference of Qwen/Qwen3-235B-A22B. Review the quantization breakdown below to see how higher precision settings impact VRAM and throughput.
NVIDIA L40 lacks sufficient VRAM for comfortable Qwen/Qwen3-235B-A22B operation with Q4 quantization.
Your 48GB GPU is 67GB short of the 115GB minimum.
Options: (1) Try Q2 or Q3 quantization for lower VRAM requirements, (2) Consider cloud GPU rental, (3) Upgrade to a GPU with at least 16GB VRAM.
| Quantization | VRAM needed | VRAM available | Estimated speed | Verdict |
|---|---|---|---|---|
| Q4 | 115GB | 48GB | 21.41 tok/s | ❌ Not recommended |
| Q8 | 230GB | 48GB | 13.91 tok/s | ❌ Not recommended |
| FP16 | 460GB | 48GB | 8.15 tok/s | ❌ Not recommended |
