|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 1.8 GiB | 3.3 GiB | Fits comfortably | 6.7 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 1.8 GiB; with the 1.5 GiB we set aside for the runtime that is 3.3 of the card's 10 GB, leaving about 6.7 GB for the context cache.
The highest-quality version that fits entirely in memory is FP16 (full quality).
This is the cheapest card on our list that runs it comfortably at Q4, at about $260.
At about $260, this card costs roughly $26 per GB of VRAM.
Running it at its full 150 W board power for 4 hours a day would use about 18 kWh a month, about $3.31 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.
