Core Ultra 7 265K with RX 7900 XTX: Bottleneck & FPS

The Core Ultra 7 265K and RX 7900 XTX leave the CPU with plenty of spare headroom at 4K: about 80 FPS on average in AAA games at High settings, with 1% lows around 62 FPS. At 1080p the Core Ultra 7 265K becomes the limit (20% CPU bottleneck at 1080p); from 1440p upward the RX 7900 XTX takes over and the CPU has capacity to spare. In esports titles such as CS2 or Valorant expect around 254 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 80 FPS with a 17% CPU bottleneck. Ray tracing costs this AMD card more than an equivalent NVIDIA GPU: about 32 FPS with RT on at 4K.

Core Ultra 7 265K + RX 7900 XTX: quick answers

Does the Core Ultra 7 265K bottleneck the RX 7900 XTX?

1080p: 20% CPU-limited. 1440p: 12% GPU-limited. UW 1440p: 27% GPU-limited. 4K: 47% GPU-limited. At 4K 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 7 265K with RX 7900 XTX get?

About 147 FPS at 1080p, 127 FPS at 1440p, 109 FPS at UW 1440p, 80 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 254 FPS at 4K.
