Core i5-12400F with RX 6600: Bottleneck & FPS

Paired with the RX 6600, the Core i5-12400F delivers roughly 57 FPS at 1080p (1% lows ≈45) in modern AAA games, which our model rates as “heavily GPU-limited”. The RX 6600 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 184 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 63 FPS. Its 8 GB of VRAM is fine at 1080p but gets tight at 4K High. With ray tracing on, expect about 17 FPS at 1080p.

Heavily GPU-limited at 1080p

The RX 6600 is the limiting part at 1080p, which is the normal and preferred situation for gaming. The Core i5-12400F has headroom for about 120 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 1080p.

Below 60 FPS and GPU-bound: enable DLSS/FSR/XeSS Quality mode or drop to Medium settings for a big frame-rate gain.
Your 165 Hz monitor can show more frames than this build delivers. Variable refresh (G-Sync/FreeSync) will keep motion smooth.

Core i5-12400F + RX 6600: quick answers

Does the Core i5-12400F bottleneck the RX 6600?

1080p: 52% GPU-limited. 1440p: 69% GPU-limited. UW 1440p: 75% GPU-limited. 4K: 83% GPU-limited. At 1080p 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 RX 6600 get?

About 57 FPS at 1080p, 37 FPS at 1440p, 30 FPS at UW 1440p, 21 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 184 FPS at 1080p.

What is the best upgrade for a Core i5-12400F + RX 6600 build?

At 1080p, the most effective upgrade is the RTX 5060 or RTX 5060 Ti 16GB. Use the calculator to check other resolutions and settings.
