Intel Arc B580 (12 GB)
This beginner GPU steps up to 12GB of VRAM at 190W on PCIe 4.0, measuring 272mm and asking for a 600W PSU. The extra capacity makes it attractive at entry pricing when stock cooperates. As with its Arc siblings, older DX9/DX11 games and slow-CPU pairings expose driver overhead, so it rewards a modern processor and current-gen titles.
