Between the Arc B770 and GeForce RTX 5070, the Arc B770 comes out ahead in vram and memory bus, while the GeForce RTX 5070 wins on cuda / stream cores and ray tracing cores. Overall, the Arc B770 scores 62.4 and the GeForce RTX 5070 scores 62.3 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (62.4 vs 62.3). 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 push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are vram, memory bus, tdp, among others.
Pick the GeForce RTX 5070 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.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
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.
