Buying advice

Which should you buy?

The Core Ultra 9 285K edges ahead on the Mars Score (56.2 vs 60.9), but the 4.7-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 care most about tdp. The biggest gaps in its favor are tdp. The single most decisive one: TDP — 60.00 W less. 65 vs 125.

Pick the Core Ultra 9 285K 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 cinebench r23 (multi), cores, l3 cache, among others. The single most decisive one: Cinebench R23 (multi) — 26.63% more. 42800 vs 33800.

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

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
