Buying advice

Which should you buy?

The Radeon RX 7800 XT edges ahead on the Mars Score (56.2 vs 62.5), but the 6.3-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Arc B580 if you care most about tdp and boost clock. The biggest gaps in its favor are tdp, boost clock.

Pick the Radeon RX 7800 XT if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are ray tracing cores, 3dmark time spy, cuda / stream cores, among others.

Both ship with comparable dlss, so those specs don't separate the two — focus on the differences below.

Bottom line: the Radeon RX 7800 XT is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
