Between the Arc B770 and Radeon RX 9070, the Arc B770 comes out ahead in boost clock and cuda / stream cores, while the Radeon RX 9070 wins on ray tracing cores and 3dmark time spy. Overall, the Arc B770 scores 62.4 and the Radeon RX 9070 scores 63.1 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (62.4 vs 63.1). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the Arc B770 if you care most about boost clock and cuda / stream cores. The biggest gaps in its favor are boost clock, cuda / stream cores.
Pick the Radeon RX 9070 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, tdp.
Both ship with comparable vram, memory bus, 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.
