Buying advice

Which should you buy?

The Core Ultra 9 285K is the clear pick on raw spec strength, leading by 9.0 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.

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 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 cores, cinebench r23 (multi), 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 9 285K is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
