Will it run your models?
VRAM meterLocal AI fit: 8B comfortably, 13B is tight. Rule of thumb for 4-bit quantized models; context length and other apps eat into the same memory.

What it costs to run
150W of board power, 4 hours a day under load, priced at the residential electricity rate where you live. Pick a state and the numbers update.
Board power is the rated maximum; real gaming load usually sits below it and idle is a few watts, so treat this as the ceiling. Rates: EIA residential average, May 2026. See every card ranked by running cost →

The editor's take
A competent 1080p card with 10GB, which beats every 8GB card in its class on memory. Its problem is family: the B580 is only $30 more at MSRP and clearly better. Buy the B570 when B580 stock dries up or its price drifts, which happens often enough that this card exists for a reason.
