Intel Core i5-14400 vs Intel Core i5-12400
Which is faster for gaming, by how much, and the resolution past which the difference stops reaching you. Reference: AMD RX 6700 XT, 32 GB of RAM.
The Intel Core i5-14400 is 7% faster than the Intel Core i5-12400 on average, but paired with an AMD RX 6700 XT that advantage disappears at 1920x1080: past that point the graphics card sets the pace and both processors deliver the same frames.
WHERE IT STOPS MATTERING
Real-world advantage of the Intel Core i5-14400 over the Intel Core i5-12400 at each resolution, paired with an AMD RX 6700 XT. A processor can only show its lead while the graphics card keeps up; the more pixels, the more the two converge.

HOW THIS IS CALCULATED
The per-game frame rates are the ceiling each processor sustains on its own, with no graphics card limiting it. That is the only honest way to compare two CPUs: fixing a specific card would turn the comparison into a review of that card.
Native resolution, no upscaling and no frame generation. Measured model error · Methodology
