Core i5-12600K with RTX 5070: Bottleneck & FPS

At 1440p, a Core i5-12600K + RTX 5070 build averages about 99 FPS in AAA games at High settings, with 1% lows near 78 FPS: GPU-limited, CPU has headroom. At 1080p the Core i5-12600K becomes the limit (12% CPU bottleneck at 1080p); from 1440p upward the RTX 5070 takes over and the CPU has capacity to spare. In esports titles such as CS2 or Valorant expect around 301 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 70 FPS with a 44% CPU bottleneck. With ray tracing enabled, expect about 59 FPS at 1440p, so turn on DLSS or FSR to get back above 60.

Core i5-12600K + RTX 5070: quick answers

Does the Core i5-12600K bottleneck the RTX 5070?

1080p: 12% CPU-limited. 1440p: 21% GPU-limited. UW 1440p: 34% GPU-limited. 4K: 52% GPU-limited. At 1440p the CPU keeps up, so this is a sensible pairing. A GPU-limited result is the normal, healthy state for gaming.

How many FPS does the Core i5-12600K with RTX 5070 get?

About 123 FPS at 1080p, 99 FPS at 1440p, 84 FPS at UW 1440p, 61 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 301 FPS at 1440p.
