Core Ultra 9 285K with RX 6800 XT: Bottleneck & FPS

The Core Ultra 9 285K and RX 6800 XT leave the CPU with plenty of spare headroom at 1440p: about 87 FPS on average in AAA games at High settings, with 1% lows around 68 FPS. The RX 6800 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 276 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 83 FPS with a 22% CPU bottleneck. Ray tracing costs this AMD card more than an equivalent NVIDIA GPU: about 28 FPS with RT on at 1440p.

Core Ultra 9 285K + RX 6800 XT: quick answers

Does the Core Ultra 9 285K bottleneck the RX 6800 XT?

1080p: 19% GPU-limited. 1440p: 44% GPU-limited. UW 1440p: 53% GPU-limited. 4K: 66% GPU-limited. At 1440p the CPU keeps up, so this is a sensible pairing. A GPU-limited result is the normal, healthy state for gaming.

How many FPS does the Core Ultra 9 285K with RX 6800 XT get?

About 122 FPS at 1080p, 87 FPS at 1440p, 72 FPS at UW 1440p, 53 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 276 FPS at 1440p.

What is the best upgrade for a Core Ultra 9 285K + RX 6800 XT build?

At 1440p, the most effective upgrade is the RTX 4080 Super or RTX 5070 Ti. Use the calculator to check other resolutions and settings.
