Apple - M4 Max vs AMD - Ryzen AI 9 HX 395+

These two are nearly even on the Mars Score (52.3 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 Ryzen AI 9 HX 395+ if you care most about l3 cache / boost clock. Its strongest claims are l3 cache, boost clock. The single most decisive one: L3 cache — 100.00% more. 64 MB vs 32 MB.
