All three quants
12GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 0.6 GiB | 2.1 GiB | Fits comfortably | 9.9 GiB |
| Q8_0near-lossless | 1.0 GiB | 2.5 GiB | Fits comfortably | 9.5 GiB |
| FP16full weights | 1.9 GiB | 3.4 GiB | Fits comfortably | 8.6 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.
The numbers for this pairing
At Q4_K_M the weights take about 0.6 GiB; with the 1.5 GiB we set aside for the runtime that is 2.1 of the card's 12 GB, leaving about 9.9 GB for the context cache.
The highest-quality version that fits entirely in memory is FP16 (full quality).
The cheapest card on our list that runs it comfortably at Q4 is the Arc B570 at about $260, against about $330 for this card.
At about $330, this card costs roughly $27 per GB of VRAM.
Running it at its full 190 W board power for 4 hours a day would use about 23 kWh a month, about $4.20 at the US average residential rate of 18.4 cents per kWh (2026-05); real use sits below that ceiling.
Prices are the lowest current listings our tracker saw on Oct 7, 2026, since averages include premium variants; launch prices are marked where we have no listing.
