Fragz' verdict
"Genuine 0000 @ 3.40GHz" clearly wins this CPU comparison, leading the "11th Gen Core i5-11400 @ 2.60GHz" by 30.8% in overall CPU score. This performance gap is driven by its higher core and thread count (8 cores/16 threads versus 6 cores/12 threads) and superior integer multi-threaded performance, hitting 6.8 Gop/s compared to 4.5 Gop/s. Gamers will see the benefit in its stronger single-thread performance of 0.59 Gop/s, which contributes to a higher FPS ceiling, as evidenced by its 71.3 FPS in Supernova DX11. However, the "Genuine 0000 @ 3.40GHz" only has one verified run, making its stellar results less certain than the "11th Gen Core i5-11400 @ 2.60GHz" which has four.

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
