Core i5-10400F with RTX 3070: Bottleneck & FPS

The Core i5-10400F and RTX 3070 pair well, with the graphics card setting the pace at 1440p: about 59 FPS on average in AAA games at High settings, with 1% lows around 46 FPS. The RTX 3070 is the limiting part at every resolution, so the 6-core Core i5-10400F (LGA1200) still has headroom for about 88 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 197 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 48 FPS with a 35% CPU bottleneck. With 8 GB of VRAM, the RTX 3070 is short of the ~10 GB modern games use at 1440p High, so drop texture quality a notch to avoid stutter.

GPU-limited, CPU has headroom at 1440p

The RTX 3070 is the limiting part at 1440p, which is the normal and preferred situation for gaming. The Core i5-10400F has headroom for about 88 FPS, so it can handle a faster GPU later. FPS is below 60, so lower settings or enable upscaling.

Recommendations

Specific to these parts at 1440p.

Below 60 FPS and GPU-bound: enable DLSS/FSR/XeSS Quality mode or drop to Medium settings for a big frame-rate gain.
8 GB of VRAM is below the ~10 GB these settings need. Lower texture quality to avoid stutter and texture pop-in.
Your 165 Hz monitor can show more frames than this build delivers. Variable refresh (G-Sync/FreeSync) will keep motion smooth.

Core i5-10400F + RTX 3070: quick answers

Does the Core i5-10400F bottleneck the RTX 3070?

1080p: balanced. 1440p: 32% GPU-limited. UW 1440p: 45% GPU-limited. 4K: 62% 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 3070 get?

About 82 FPS at 1080p, 59 FPS at 1440p, 48 FPS at UW 1440p, 33 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 197 FPS at 1440p.

What is the best upgrade for a Core i5-10400F + RTX 3070 build?

At 1440p, the most effective upgrade is the RTX 4070 Super or RX 7700 XT. Use the calculator to check other resolutions and settings.
