Core i5-10400F with RTX 4070: Bottleneck & FPS

Paired with the RTX 4070, the Core i5-10400F delivers roughly 78 FPS at 1440p (1% lows ≈59) in modern AAA games, which our model rates as “excellent balance”. At 1080p the Core i5-10400F becomes the limit (26% CPU bottleneck at 1080p); from 1440p upward the RTX 4070 takes over and the CPU has capacity to spare. In esports titles such as CS2 or Valorant expect around 222 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 48 FPS with a 54% CPU bottleneck. With ray tracing enabled, expect about 48 FPS at 1440p, so turn on DLSS or FSR to get back above 60.

Core i5-10400F + RTX 4070: quick answers

Does the Core i5-10400F bottleneck the RTX 4070?

1080p: 26% CPU-limited. 1440p: balanced. UW 1440p: 21% GPU-limited. 4K: 43% 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 i5-10400F with RTX 4070 get?

About 87 FPS at 1080p, 78 FPS at 1440p, 68 FPS at UW 1440p, 51 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 222 FPS at 1440p.

What is the best upgrade for a Core i5-10400F + RTX 4070 build?

None is needed at 1440p. The Core i5-10400F and RTX 4070 are well matched, so upgrade only when you want more FPS overall.
