Core i5-13400F with RX 7900 XT: Bottleneck & FPS

The Core i5-13400F and RX 7900 XT are well balanced at 1440p: about 108 FPS on average in AAA games at High settings, with 1% lows around 82 FPS. At 1080p the Core i5-13400F becomes the limit (22% CPU bottleneck at 1080p); from 1440p upward the RX 7900 XT takes over and the CPU has capacity to spare. In esports titles such as CS2 or Valorant expect around 312 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 69 FPS with a 51% CPU bottleneck. Ray tracing costs this AMD card more than an equivalent NVIDIA GPU: about 46 FPS with RT on at 1440p.

Core i5-13400F + RX 7900 XT: quick answers

Does the Core i5-13400F bottleneck the RX 7900 XT?

1080p: 22% CPU-limited. 1440p: 11% GPU-limited. UW 1440p: 26% GPU-limited. 4K: 46% 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 i5-13400F with RX 7900 XT get?

About 124 FPS at 1080p, 108 FPS at 1440p, 93 FPS at UW 1440p, 68 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 312 FPS at 1440p.

What is the best upgrade for a Core i5-13400F + RX 7900 XT build?

None is needed at 1440p. The Core i5-13400F and RX 7900 XT are well matched, so upgrade only when you want more FPS overall.
