Core i5-12400F with RTX 4070: Bottleneck & FPS

The Core i5-12400F and RTX 4070 pair well, with the graphics card setting the pace at 1440p: about 83 FPS on average in AAA games at High settings, with 1% lows around 65 FPS. The RTX 4070 is the limiting part at every resolution, so the 6-core Core i5-12400F (LGA1700) still has headroom for about 120 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 259 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 66 FPS with a 37% CPU bottleneck. With ray tracing enabled, expect about 48 FPS at 1440p, so turn on DLSS or FSR to get back above 60.

Core i5-12400F + RTX 4070: quick answers

Does the Core i5-12400F bottleneck the RTX 4070?

1080p: balanced. 1440p: 30% GPU-limited. UW 1440p: 42% GPU-limited. 4K: 58% 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 4070 get?

About 110 FPS at 1080p, 83 FPS at 1440p, 70 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 259 FPS at 1440p.

What is the best upgrade for a Core i5-12400F + RTX 4070 build?

At 1440p, the most effective upgrade is the RTX 5080 or RTX 4070 Super. Use the calculator to check other resolutions and settings.
