Between the Arc B580 and Arc B770, the Arc B580 comes out ahead in tdp, while the Arc B770 wins on cuda / stream cores and ray tracing cores. Overall, the Arc B580 scores 56.2 and the Arc B770 scores 62.4 on our Mars Score.
Which should you buy?
The Arc B770 edges ahead on the Mars Score (56.2 vs 62.4), but the 6.2-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. The biggest gaps in its favor are tdp.
Pick the Arc B770 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 cuda / stream cores, ray tracing cores, 3dmark time spy, among others.
Both ship with comparable dlss, so those specs don't separate the two — focus on the differences below.
Bottom line: the Arc B770 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
