Fits, tight on context at Q4_K_M.
Codestral 22B v0.1 is 22.2B parameters. At Q4_K_M the weights are about 12.4 GiB; with the 1.5 GiB runtime reserve that is 13.9 GiB against the card's 16GB, leaving about 2.1 GiB for context.
All three quants
16GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 12.4 GiB | 13.9 GiB | Fits, tight on context | 2.1 GiB |
| Q8_0near-lossless | 21.9 GiB | 23.4 GiB | Only with CPU offload | short 7.4 GiB |
| FP16full weights | 41.4 GiB | 42.9 GiB | Does not fit | short 26.9 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.
The numbers for this pairing
At Q4_K_M the weights take about 12.4 GiB; with the 1.5 GiB we set aside for the runtime that is 13.9 of the card's 16 GB, leaving about 2.1 GB for the context cache.
The cheapest card on our list that runs it comfortably at Q4 is the Radeon RX 7900 XTX at about $850, against about $599 for this card.
At about $599, this card costs roughly $37 per GB of VRAM.
Running it at its full 263 W board power for 4 hours a day would use about 32 kWh a month, about $5.81 at the US average residential rate of 18.4 cents per kWh (2026-05); real use sits below that ceiling.
