Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Apple - M3 Max | Intel - Core Ultra 5 225 |
|---|---|---|
| Cores | 16 | 10 |
| L3 cache | 32 MB | 20 MB |
| Cinebench R23 (multi) | 26800 | 18200 |
| Boost clock | 4.05 GHz | 4.9 GHz |
| TDP | 60 W | 65 W |
Between the M3 Max and Core Ultra 5 225, the M3 Max comes out ahead in cores / l3 cache, while the Core Ultra 5 225 wins on boost clock. Overall, the M3 Max scores 50 and the Core Ultra 5 225 scores 47.8 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (50 vs 47.8). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.
Pick the M3 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 cores, l3 cache, cinebench r23 (multi), among others. The single most decisive one: Cores — 60.00% more. 16 vs 10.
Pick the Core Ultra 5 225 if you care most about boost clock. Its strongest claims are boost clock. The single most decisive one: Boost clock — 20.99% more. 4.9 GHz vs 4.05 GHz.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
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 - M3 Max or Intel - Core Ultra 5 225?
Apple - M3 Max leads the current Mars Score by 2.2 points.The more useful decision is the trade-off behind that result: compare cores, boost clock, tdp against the way you will actually use the product.
