Between the Arc B570 and Arc B770, the Arc B570 comes out ahead in tdp, while the Arc B770 wins on cuda / stream cores and ray tracing cores. Overall, the Arc B570 scores 54.1 and the Arc B770 scores 62.4 on our Mars Score.
Which should you buy?
The Arc B770 is the clear pick on raw spec strength, leading by 8.3 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the Arc B570 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, vram, 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.
