Fragz' verdict
The Core Ultra 7 270K Plus takes a commanding lead in this comparison, outperforming the 13th Gen Core i5-13420H by 118.3% in overall CPU score. This substantial difference is backed by its superior multi-threaded integer performance, hitting 12.7 Gop/s compared to the i5's 4.3 Gop/s, alongside a stronger single-thread showing of 0.69 Gop/s against 0.53 Gop/s. For gamers, this means better handling of background tasks and a higher FPS ceiling, clearly demonstrated in the Supernova DX11 scene where the Core Ultra 7 270K Plus achieved 113.9 FPS versus the 13th Gen Core i5-13420H's 76.2 FPS. The Core Ultra 7's significantly higher core/thread count (24/24 vs 8/12) and larger L3 cache (36 MB vs 12 MB) explain its dominant performance, even with the 13th Gen Core i5-13420H's slightly higher peak clock of 5664 MHz. It's important to note, however, that both CPUs currently only have a single verified run each, so these results are preliminary and should be viewed with that thin sample in mind.

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
