Core i5-10400F with RX 6600: Bottleneck & FPS

The Core i5-10400F and RX 6600 pair well, with the graphics card setting the pace at 1080p: about 57 FPS on average in AAA games at High settings, with 1% lows around 45 FPS. The RX 6600 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 180 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 48 FPS with a 33% CPU bottleneck. 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.

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.
