Which should you buy?
Buy the Arc B580 if you want the faster card: it's 21% ahead at 4K. The RTX 3060 12GB is the better buy only if it costs at least 21% less, the gap at 1440p, because then it delivers more frames per dollar. Already own the RTX 3060 12GB? Going to the Arc B580 gains 21% at 1440p, which is a modest upgrade, worth it mainly if you can sell the RTX 3060 12GB.
Buy the Arc B580 if…
- you want the most FPS: it's 21% faster at 4K and 21% at 1440p.
- you play with ray tracing: 29 vs 25 FPS at 1440p.
- you want the newer card (2024) with the longer driver and feature support ahead of it.
Buy the RTX 3060 12GB if…
- it costs at least 21% less than the Arc B580, which makes it the better value per frame.
- it's the cheaper of the two where you shop: performance is close enough that price decides.
