Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Apple - M4 Ultra | Intel - Core i7-14700K |
|---|---|---|
| L3 cache | 64 MB | 33 MB |
| Cores | 32 | 20 |
| Cinebench R23 (multi) | 52600 | 35200 |
| Boost clock | 4.5 GHz | 5.6 GHz |
| TDP | 120 W | 125 W |
Between the M4 Ultra and Core i7-14700K, the M4 Ultra comes out ahead in l3 cache / cores, while the Core i7-14700K wins on boost clock. Overall, the M4 Ultra scores 63.1 and the Core i7-14700K scores 57.8 on our Mars Score.
Which should you buy?
The M4 Ultra edges ahead on the Mars Score (63.1 vs 57.8), but the 5.3-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the M4 Ultra 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 l3 cache, cores, cinebench r23 (multi), among others. The single most decisive one: L3 cache — 93.94% more. 64 MB vs 33 MB.
Pick the Core i7-14700K if you care most about boost clock. Its strongest claims are boost clock. The single most decisive one: Boost clock — 24.44% more. 5.6 GHz vs 4.5 GHz.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
Bottom line: the M4 Ultra is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
Which should you buy: Apple - M4 Ultra or Intel - Core i7-14700K?
Apple - M4 Ultra leads the current Mars Score by 5.3 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.
