Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Apple - M4 Max | Intel - Core Ultra 9 285H |
|---|---|---|
| Cinebench R23 (multi) | 29800 | 21500 |
| L3 cache | 32 MB | 24 MB |
| Boost clock | 4.5 GHz | 5.4 GHz |
| TDP | 55 W | 45 W |
Between the M4 Max and Core Ultra 9 285H, the M4 Max comes out ahead in cinebench r23 (multi) / l3 cache, while the Core Ultra 9 285H wins on boost clock / tdp. Overall, the M4 Max scores 52.3 and the Core Ultra 9 285H scores 51.2 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (52.3 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 M4 Max 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), l3 cache. The single most decisive one: Cinebench R23 (multi) — 38.60% more. 29800 vs 21500.
Pick the Core Ultra 9 285H if you care most about boost clock / tdp. Its strongest claims are boost clock, tdp. The single most decisive one: Boost clock — 20.00% more. 5.4 GHz vs 4.5 GHz.
Both ship with comparable cores, 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.
Which should you buy: Apple - M4 Max or Intel - Core Ultra 9 285H?
Apple - M4 Max leads the current Mars Score by 1.1 points.The more useful decision is the trade-off behind that result: compare boost clock, tdp against the way you will actually use the product.
