Core i5-12400F with RTX 5070: Bottleneck & FPS

Paired with the RTX 5070, the Core i5-12400F delivers roughly 98 FPS at 1440p (1% lows ≈76) in modern AAA games, which our model rates as “well balanced (GPU-bound)”. At 1080p the Core i5-12400F becomes the limit (17% 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 291 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 66 FPS with a 48% CPU bottleneck. With ray tracing enabled, expect about 59 FPS at 1440p, so turn on DLSS or FSR to get back above 60.

Core i5-12400F + RTX 5070: quick answers

Does the Core i5-12400F bottleneck the RTX 5070?

1080p: 17% CPU-limited. 1440p: 16% GPU-limited. UW 1440p: 30% GPU-limited. 4K: 49% 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 i5-12400F with RTX 5070 get?

About 117 FPS at 1080p, 98 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 291 FPS at 1440p.

What is the best upgrade for a Core i5-12400F + RTX 5070 build?

None is needed at 1440p. The Core i5-12400F and RTX 5070 are well matched, so upgrade only when you want more FPS overall.
