The Verdict
Based on our benchmark database and scoring, the Intel Core Ultra 9 285K wins on gaming by about 2 points, the Intel Core Ultra 9 285K pulls ahead in productivity by 20 points. Overall the Intel Core Ultra 9 285K comes out ahead in this matchup, but the right pick depends on what you're actually building: gaming-first rigs favor higher single-thread and 3D V-Cache designs, while streaming and content-creation rigs benefit more from raw multi-core output. Note the socket mismatch — the Intel Core Ultra 9 285K needs an LGA 1851 motherboard, the Intel Core i5-14600K needs LGA 1700, so these aren't drop-in swaps on the same platform.
