Which should you buy?
The Ryzen AI 9 HX 395+ edges ahead on the Mars Score (49.8 vs 54.3), but the 4.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Ryzen 7 7800X3D if you care most about l3 cache. The biggest gaps in its favor are l3 cache.
Pick the Ryzen AI 9 HX 395+ 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 cores, tdp, cinebench r23 (multi), among others.
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 tells you both are well-rounded; the differences are about trade-offs, not quality.
