Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Intel - Core Ultra 7 265 | AMD - Ryzen AI 9 HX 395+ |
|---|---|---|
| L3 cache | 30 MB | 64 MB |
| Cores | 20 | 16 |
| Cinebench R23 (multi) | 33800 | 27500 |
| TDP | 65 W | 55 W |
| Boost clock | 5.3 GHz | 5.1 GHz |
Between the Core Ultra 7 265 and Ryzen AI 9 HX 395+, the Core Ultra 7 265 comes out ahead in cores / cinebench r23 (multi), while the Ryzen AI 9 HX 395+ wins on l3 cache / tdp. Overall, the Core Ultra 7 265 scores 56.2 and the Ryzen AI 9 HX 395+ scores 54.3 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (56.2 vs 54.3). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.
Pick the Core Ultra 7 265 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, cinebench r23 (multi), boost clock. The single most decisive one: Cores — 25.00% more. 20 vs 16.
Pick the Ryzen AI 9 HX 395+ if you care most about l3 cache / tdp. Its strongest claims are l3 cache, tdp. The single most decisive one: L3 cache — 113.33% more. 64 MB vs 30 MB.
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: Intel - Core Ultra 7 265 or AMD - Ryzen AI 9 HX 395+?
Intel - Core Ultra 7 265 leads the current Mars Score by 1.9 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.
