Fragz' verdict
The 13th Gen Core i9-13900K decisively outperforms the Core i5-7500, leading by an impressive 217.7% in overall CPU score, though both only have two verified runs, making the sample thin. This massive lead is evident in its single-thread performance, hitting 0.88 Gop/s compared to the i5's 0.41 Gop/s, driven by a significantly higher peak clock of 6119 MHz versus 3708 MHz. For multi-threaded tasks like streaming and compiling, the i9's 12.5 Gop/s integer performance, 24 cores/32 threads, and 36 MB of L3 cache dwarf the i5's 1.9 Gop/s, 4 cores/4 threads, and 6 MB. In the Supernova DX11 scene, the i9 delivers 77.9 FPS and processes 9,342,700 draw calls per second, well above the i5's 53.1 FPS and 6,364,061 draw calls per second. The Core i5-7500, ranking 90th out of 97, is only suitable for very basic computing or if you are upgrading from an even older system and already have the chip, as its gaming performance is significantly limited.

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
