Ryzen 7 7800X3D with RX 7900 XTX: Bottleneck & FPS

Paired with the RX 7900 XTX, the Ryzen 7 7800X3D delivers roughly 80 FPS at 4K (1% lows ≈65) in modern AAA games, which our model rates as “heavily GPU-limited”. The RX 7900 XTX is the limiting part at every resolution, so the 8-core Ryzen 7 7800X3D (AM5) still has headroom for about 176 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 255 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 90 FPS. Ray tracing costs this AMD card more than an equivalent NVIDIA GPU: about 32 FPS with RT on at 4K.
