Core Ultra 9 285K with RX 7900 XT: Bottleneck & FPS

At 1440p, a Core Ultra 9 285K + RX 7900 XT build averages about 111 FPS in AAA games at High settings, with 1% lows near 87 FPS: GPU-limited, CPU has headroom. The RX 7900 XT is the limiting part at every resolution, so the 24-core Core Ultra 9 285K (LGA1851) still has headroom for about 154 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 344 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 85 FPS with a 40% CPU bottleneck. Ray tracing costs this AMD card more than an equivalent NVIDIA GPU: about 46 FPS with RT on at 1440p.
