Can the GeForce RTX 3060 12GB (used) run Qwen3 32B?
Only with CPU offload at Q4_K_M.
Qwen3 32B is 32.8B parameters. At Q4_K_M the weights are about 18.3 GiB; with the 1.5 GiB runtime reserve that is 19.8 GiB against the card's 12GB, about 7.8 GiB more than the card has.
All three quants
12GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 18.3 GiB | 19.8 GiB | Only with CPU offload | short 7.8 GiB |
| Q8_0near-lossless | 32.4 GiB | 33.9 GiB | Does not fit | short 21.9 GiB |
| FP16full weights | 61.1 GiB | 62.6 GiB | Does not fit | short 50.6 GiB |
Verdict rules: fits comfortably when weights plus reserve sit within 85% of VRAM; tight when they fit with little left for context; CPU offload when they exceed VRAM by up to 2x (runs, slowly, with layers in system RAM); no beyond that. The KV cache per token depends on the model's architecture and is not modelled here.
Not this card. These fit it comfortably at Q4.
