Buying advice

Which should you buy?

These two are nearly even on the Mars Score (50.7 vs 51.9). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the M4 Max (16-core) 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 tdp, l3 cache, cinebench r23 (multi).

Pick the Core Ultra 5 245K if you care most about boost clock. Its strongest claims are boost clock.

Both ship with comparable cores, 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.
