Why This Bottleneck Occurs
At 1440p resolution for gaming, the Intel Core i5-12600KF creates a significant bottleneck (40%) when paired with the NVIDIA GeForce RTX 4090. The CPU cannot feed data to the GPU fast enough, meaning the NVIDIA GeForce RTX 4090 is not being fully utilized. At 1440p, the workload is more balanced, but the CPU is still the limiting factor in this pairing.
