Buying advice

Which should you buy?

The GeForce RTX 5080 is the clear pick on raw spec strength, leading by 9.5 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 B770 if you care most about tdp and boost clock. The biggest gaps in its favor are tdp, boost clock.

Pick the GeForce RTX 5080 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 5080 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
