Fragz' verdict
The 13th Gen Core i9-13900K absolutely dominates this comparison, leading the Core i7-7700 by a massive 151.3% in component score. This performance gap is evident across the board, with the 13th Gen Core i9-13900K delivering significantly higher multi-threaded integer performance (12.5 Gop/s vs 2.1 Gop/s), nearly double the single-thread performance (0.88 Gop/s vs 0.46 Gop/s), and a much higher draw calls per second (9.3 million vs 6.4 million). For gamers, this means a far higher FPS ceiling in games due to superior single-thread power, coupled with better handling of background tasks and streaming thanks to its 24 cores and 32 threads compared to the Core i7-7700's 4 cores and 8 threads. The Supernova DX11 test also shows a clear lead, hitting 77.9 FPS versus 53.8 FPS. It's worth noting that both CPUs have thin sample sizes with only one or two verified runs each, so there's some uncertainty. While the Core i7-7700 is clearly outclassed, it might still serve as a basic gaming CPU if you already own it and are not chasing high frame rates, though its low component rank of 76 out of 93 shows it's far from a top performer today.

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
