Why This Bottleneck Occurs
At 1080p resolution for gaming, the AMD A8-6600K (Desktop) 3.90 GHz creates a significant bottleneck (35%) when paired with the AMD Radeon RX 6750 XT. The CPU cannot feed data to the GPU fast enough, meaning the AMD Radeon RX 6750 XT is not being fully utilized. At 1080p, the CPU is under heavier load because frame rates are higher and the GPU finishes frames faster.
