Fragz' verdict
The Core Ultra 9 285K decisively takes the lead over the Ryzen 5 5600X, boasting a 92.3% higher CPU score; however, it's important to note that the Core Ultra 9 285K has only one verified run, making the sample thin. This performance gap is evident across key metrics: the Core Ultra 9 285K delivers significantly higher single-thread performance at 0.95 Gop/s compared to the Ryzen's 0.57 Gop/s, which often dictates gaming FPS ceilings. It also excels in multi-threaded integer operations with 12.7 Gop/s versus 4.9 Gop/s, and pushes more draw calls per second at 11,963,538, leading to a much higher 99.8 FPS in our Supernova DX11 test. With its 24 cores and 24 threads, the Core Ultra 9 285K offers a substantial uplift in raw compute and gaming-relevant performance. While the Ryzen 5 5600X, with its 6 cores and 12 threads and a rank of 49, remains a respectable chip, the Core Ultra 9 285K is clearly the powerhouse here.

What the numbers mean
The CPU score is the processor's own performance — that is what we rank on. GAMING is the whole rig's score in the best PC we measured the processor in, and leans heavily on the graphics card. A strong processor in a weak PC gets a low GAMING score without being worse. We show both and never mix them.
All numbers come from our benchmark suite: four hand-built 3D scenes written directly against the graphics APIs in Rust, the same load on every PC. The methodology is open at https://whatfps.com/metodik
