Ryzen 7 7800X3D with RTX 5080: Bottleneck & FPS

The Ryzen 7 7800X3D and RTX 5080 leave the CPU with plenty of spare headroom at 4K: about 86 FPS on average in AAA games at High settings, with 1% lows around 70 FPS. At 1080p the Ryzen 7 7800X3D becomes the limit (13% CPU bottleneck at 1080p); from 1440p upward the RTX 5080 takes over and the CPU has capacity to spare. In esports titles such as CS2 or Valorant expect around 273 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 92 FPS. With ray tracing enabled, expect about 50 FPS at 4K, so turn on DLSS or FSR to get back above 60.

Heavily GPU-limited at 4K

The RTX 5080 is the limiting part at 4K, which is the normal and preferred situation for gaming. The Ryzen 7 7800X3D has headroom for about 176 FPS, so it can handle a faster GPU later.

Max frames each part can deliver. Frames pile up in front of the slower one.
