Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Apple - M3 Max | Apple - M4 Max (16-core) |
|---|---|---|
| TDP | 60 W | 45 W |
| Cores | 16 | 14 |
| L3 cache | 32 MB | 28 MB |
| Boost clock | 4.05 GHz | 4.5 GHz |
| Cinebench R23 (multi) | 26800 | 26500 |
Between the M3 Max and M4 Max (16-core), the M3 Max comes out ahead in cores / l3 cache, while the M4 Max (16-core) wins on tdp / boost clock. Overall, the M3 Max scores 50 and the M4 Max (16-core) scores 50.7 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (50 vs 50.7). 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). The single most decisive one: Cores — 14.29% more. 16 vs 14.
Pick the M4 Max (16-core) if you care most about tdp / boost clock. Its strongest claims are tdp, boost clock. The single most decisive one: TDP — 15.00 W less. 45 vs 60.
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 Apple - M4 Max (16-core)?
Apple - M4 Max (16-core) leads the current Mars Score by 0.7 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.
