All three quants
16GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 2.6 GiB | 4.1 GiB | Fits comfortably | 11.9 GiB |
| Q8_0near-lossless | 4.6 GiB | 6.1 GiB | Fits comfortably | 9.9 GiB |
| FP16full weights | 8.7 GiB | 10.2 GiB | Fits comfortably | 5.8 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.
