Measured comparison

Fragz' verdict

Based on the single verified runs we have for each, the Core Ultra 7 270K Plus is the clear winner in this CPU showdown, boasting a 51.9% higher CPU score than the Core i9-9900K. This performance lead is driven by its stronger single-thread performance of 0.69 Gop/s compared to the Core i9-9900K's 0.59 Gop/s, which is a key factor in setting the FPS ceiling for many games. The Core Ultra 7 270K Plus also delivers significantly better multi-threaded integer performance at 12.7 Gop/s, nearly double the Core i9-9900K's 6.5 Gop/s, alongside a higher 13.6 million draw calls per second and 113.9 FPS in our Supernova DX11 test. These gains are supported by its higher core and thread count (24/24 versus 8/16), increased L3 cache at 36 MB, and a faster peak clock speed of 5412 MHz.

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
