Measured comparison

Fragz' verdict

The Core Ultra 7 265K takes the overall lead in CPU score, coming in 4.1% ahead of the Ryzen 7 9850X3D, though both only have a single verified run. This advantage appears to stem from its superior multi-threaded integer performance of 11.5 Gop/s, backed by its 20 cores and 20 threads. However, for pure gaming, the Ryzen 7 9850X3D looks compelling with its higher single-thread integer performance of 0.92 Gop/s, 15,765,407 draw calls per second, and a significantly higher 131.4 FPS in the Supernova DX11 test, plus its larger 96 MB L3 cache. If your priority is raw in-game frame rates and responsiveness, the Ryzen 7 9850X3D's stronger single-threaded metrics and DX11 performance could make it the better choice, despite the Core Ultra 7 265K's overall score lead.

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
