Intel - Arc B580 vs NVIDIA - GeForce RTX 4090

The GeForce RTX 4090 is the clear pick on raw spec strength, leading by 24.1 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 B580 if you care most about tdp and boost clock. The biggest gaps in its favor are tdp, boost clock.

Pick the GeForce RTX 4090 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: the GeForce RTX 4090 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
