Intel - Core Ultra 5 245K vs Intel - Core Ultra 7 265K

The Core Ultra 7 265K edges ahead on the Mars Score (51.9 vs 57.7), but the 5.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.

The Core Ultra 5 245K doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.

Pick the Core Ultra 7 265K 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.

Both ship with comparable tdp, so those specs don't separate the two — focus on the differences below.

Bottom line: the Core Ultra 7 265K is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
