Core i5-13600K with RX 7900 XT: Bottleneck & FPS

The Core i5-13600K and RX 7900 XT pair well, with the graphics card setting the pace at 1440p: about 111 FPS on average in AAA games at High settings, with 1% lows around 86 FPS. The RX 7900 XT is the limiting part at every resolution, so the 14-core Core i5-13600K (LGA1700) still has headroom for about 146 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 338 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 80 FPS with a 43% CPU bottleneck. Ray tracing costs this AMD card more than an equivalent NVIDIA GPU: about 46 FPS with RT on at 1440p.
