Between the Arc B770 and GeForce RTX 5070 Ti, the Arc B770 comes out ahead in tdp and boost clock, while the GeForce RTX 5070 Ti wins on cuda / stream cores and ray tracing cores. Overall, the Arc B770 scores 62.4 and the GeForce RTX 5070 Ti scores 67.6 on our Mars Score.
Which should you buy?
The GeForce RTX 5070 Ti edges ahead on the Mars Score (62.4 vs 67.6), but the 5.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Arc B770 if you care most about tdp and boost clock. The biggest gaps in its favor are tdp, boost clock.
Pick the GeForce RTX 5070 Ti 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 vram, memory bus, so those specs don't separate the two — focus on the differences below.
Bottom line: the GeForce RTX 5070 Ti is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
