Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Intel - Core Ultra 5 225 | AMD - Ryzen 7 9700X |
|---|---|---|
| L3 cache | 20 MB | 32 MB |
| Cinebench R23 (multi) | 18200 | 22800 |
| Cores | 10 | 8 |
| Boost clock | 4.9 GHz | 5.5 GHz |
Between the Core Ultra 5 225 and Ryzen 7 9700X, the Core Ultra 5 225 comes out ahead in cores, while the Ryzen 7 9700X wins on l3 cache / cinebench r23 (multi). Overall, the Core Ultra 5 225 scores 47.8 and the Ryzen 7 9700X scores 51.5 on our Mars Score.
Which should you buy?
The Ryzen 7 9700X edges ahead on the Mars Score (47.8 vs 51.5), but the 3.7-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Core Ultra 5 225 if you care most about cores. The biggest gaps in its favor are cores. The single most decisive one: Cores — 25.00% more. 10 vs 8.
Pick the Ryzen 7 9700X if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are l3 cache, cinebench r23 (multi), boost clock. The single most decisive one: L3 cache — 60.00% more. 32 MB vs 20 MB.
Both ship with comparable tdp, 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: Intel - Core Ultra 5 225 or AMD - Ryzen 7 9700X?
AMD - Ryzen 7 9700X leads the current Mars Score by 3.7 points.The more useful decision is the trade-off behind that result: compare cores, boost clock against the way you will actually use the product.
