Apple - M4 Max (16-core) vs Intel - Core Ultra 5 245K
Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Apple - M4 Max (16-core) | Intel - Core Ultra 5 245K |
|---|---|---|
| TDP | 45 W | 125 W |
| L3 cache | 28 MB | 24 MB |
| Boost clock | 4.5 GHz | 5.2 GHz |
| Cinebench R23 (multi) | 26500 | 25400 |
Between the M4 Max (16-core) and Core Ultra 5 245K, the M4 Max (16-core) comes out ahead in tdp / l3 cache, while the Core Ultra 5 245K wins on boost clock. Overall, the M4 Max (16-core) scores 50.7 and the Core Ultra 5 245K scores 51.9 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (50.7 vs 51.9). 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 (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). The single most decisive one: TDP — 80.00 W less. 45 vs 125.
Pick the Core Ultra 5 245K if you care most about boost clock. Its strongest claims are boost clock. The single most decisive one: Boost clock — 15.56% more. 5.2 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 (16-core) or Intel - Core Ultra 5 245K?
Intel - Core Ultra 5 245K leads the current Mars Score by 1.2 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.
