At 1080p (Full HD), the Intel Core i7-8700K will hold back the AMD RX 7700 XT by roughly 11-15% depending on the game - CPU-heavy titles will feel it most. The processor cannot feed frames to the GPU fast enough, so you may see lower-than-expected frame rates. Upgrading to a faster CPU would unlock the full potential of your AMD RX 7700 XT.

These are estimates, not benchmarks. Your actual frame rate depends on your exact settings, resolution scaling, drivers, and the scene on screen - treat these as a realistic ballpark at high settings, not a guarantee. Lower settings or upscaling (DLSS/FSR) push them higher; maxed-out ray tracing pushes them lower.
