Core i5-12400F with RX 7800 XT: Bottleneck & FPS

At 1440p, a Core i5-12400F + RX 7800 XT build averages about 87 FPS in AAA games at High settings, with 1% lows near 68 FPS: GPU-limited, CPU has headroom. The RX 7800 XT 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. Ray tracing costs this AMD card more than an equivalent NVIDIA GPU: about 36 FPS with RT on at 1440p.
