Intel - Core Ultra 5 245K vs Intel - Core Ultra 9 285H

These two are nearly even on the Mars Score (51.9 vs 51.2). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the Core Ultra 5 245K 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 cinebench r23 (multi).

Pick the Core Ultra 9 285H if you care most about tdp and cores. Its strongest claims are tdp, cores, boost clock.

Both ship with comparable l3 cache, so those specs don't separate the two — focus on the differences below.

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