Buying advice

Which should you buy?

The Core Ultra 7 265 edges ahead on the Mars Score (56.2 vs 49.8), but the 6.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Core Ultra 7 265 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 cores, cinebench r23 (multi), tdp, among others.

Pick the Ryzen 7 7800X3D if you care most about l3 cache. Its strongest claims are l3 cache.

There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
