CPU and GPU Roles

The scaling between resolutions and presets in the recorded data reveals how the CPU and GPU each contribute to performance in Doom. The CPU's role is most visible at lower resolutions where frame rates are highest. At 1920x1080, the difference between Low and Ultra is 67.7 FPS, from 251.4 to 183.7, while at 2560x1440 the same preset jump produces a 73 FPS drop, from 193.1 to 120.1. At 3840x2160, the difference from Low to Ultra is 42.4 FPS, from 103.4 to 61. The smaller absolute gap at 4K suggests that the GPU becomes the primary performance limiter as resolution increases.

At 1080p, where frame rates exceed 183 FPS at all settings, the CPU's processing capability becomes more relevant. The Core i5-9400 with its six cores and six threads, boosting to 4.1 GHz, must sustain frame rates above 180 FPS, and the data shows it does so. At 1440p, the GPU's workload increases, yet frame rates remain between 120 and 193 FPS, indicating both components handle the load without bottlenecking. At 4K, the GPU's influence dominates, with Ultra dropping to 61 FPS while Low produces 103.4 FPS, a difference of 42.4 FPS driven primarily by GPU rendering load.

The pattern across resolutions and presets shows the GPU matters more at higher resolutions, while the CPU has a stronger relative impact at lower resolutions. However, the data also shows that even at 1080p Low, the frame rate reaches 251.4 FPS, and at 1080p Ultra it reaches 183.7 FPS, indicating no severe CPU limitation at any tested setting. The balance between the two components allows for high frame rates across the board in Doom.
