Buying advice

Which should you buy?

The M4 Ultra edges ahead on the Mars Score (63.1 vs 57.7), but the 5.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the M4 Ultra 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 l3 cache, cores, cinebench r23 (multi), among others.

Pick the Core Ultra 7 265K if you care most about boost clock. Its strongest claims are boost clock.

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

Bottom line: the M4 Ultra is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
