AMD Ryzen 7 9800X3D vs Intel Core Ultra 9 285K
Head-to-head CPU comparison: cores, clocks, cache, benchmarks, and value. Which belongs in your next build?
AMD Ryzen 7 9800X3D
The pure gaming pick. The 9800X3D is the fastest gaming CPU ever made — beating even the 9950X3D in some titles thanks to its single-CCD design. If your build is gaming-first and you're not running CPU-heavy workloads, this is the sweet spot.

The Verdict
Based on our benchmark database and scoring, the AMD Ryzen 7 9800X3D wins on gaming by about 17 points, the Intel Core Ultra 9 285K pulls ahead in productivity by 18 points. Overall the AMD Ryzen 7 9800X3D 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 AMD Ryzen 7 9800X3D needs an AM5 motherboard, the Intel Core Ultra 9 285K needs LGA 1851, so these aren't drop-in swaps on the same platform.
