Core i7-13700K with RTX 4080 Super: Bottleneck & FPS

The Core i7-13700K and RTX 4080 Super leave the CPU with plenty of spare headroom at 4K: about 78 FPS on average in AAA games at High settings, with 1% lows around 61 FPS. At 1080p the Core i7-13700K becomes the limit (18% CPU bottleneck at 1080p); from 1440p upward the RTX 4080 Super takes over and the CPU has capacity to spare. In esports titles such as CS2 or Valorant expect around 248 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 80 FPS with a 15% CPU bottleneck. With ray tracing enabled, expect about 45 FPS at 4K, so turn on DLSS or FSR to get back above 60.

Core i7-13700K + RTX 4080 Super: quick answers

Does the Core i7-13700K bottleneck the RTX 4080 Super?

1080p: 18% CPU-limited. 1440p: 14% GPU-limited. UW 1440p: 29% GPU-limited. 4K: 48% 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 i7-13700K with RTX 4080 Super get?

About 147 FPS at 1080p, 125 FPS at 1440p, 106 FPS at UW 1440p, 78 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 248 FPS at 4K.
