Between the Arc B570 and Arc B580, the Arc B570 comes out ahead in tdp, while the Arc B580 wins on vram and memory bus. Overall, the Arc B570 scores 54.1 and the Arc B580 scores 56.2 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (54.1 vs 56.2). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the Arc B570 if you care most about tdp. The biggest gaps in its favor are tdp.
Pick the Arc B580 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 vram, memory bus, 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: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
