Core i5-12400F with RTX 3080: Bottleneck & FPS

The Core i5-12400F and RTX 3080 pair well, with the graphics card setting the pace at 1440p: about 87 FPS on average in AAA games at High settings, with 1% lows around 68 FPS. The RTX 3080 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 270 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 66 FPS with a 40% CPU bottleneck. Its 10 GB of VRAM is fine at 1440p but gets tight at 4K High. With ray tracing on, expect about 46 FPS at 1440p.
