AMD Ryzen 5 5600X
The eternal budget champion. AM4 platform is mature, B450/B550 boards are dirt cheap, and 6 fast cores still play modern games well at 1080p. Often the foundation for sub-$700 gaming PCs.

The Verdict
Based on our benchmark database and scoring, the Intel Core Ultra 9 285K wins on gaming by about 17 points, the Intel Core Ultra 9 285K pulls ahead in productivity by 51 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 AMD Ryzen 5 5600X needs AM4, so these aren't drop-in swaps on the same platform.
