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 is not about overall quality — both clear the bar — it is 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). The single most decisive one: Cinebench R23 (multi) — 18.14% more. 25400 vs 21500.

Pick the Core Ultra 9 285H if you care most about tdp / cores. Its strongest claims are tdp, cores, boost clock. The single most decisive one: TDP — 80.00 W less. 45 vs 125.

Both ship with comparable l3 cache, so those specs do not 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 says both are well-rounded; the differences are about trade-offs, not quality.
