The CPU's Zen 3 architecture, codenamed Vermeer, operates on the AMD Socket AM4 platform with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. This clock speed range, combined with a 32 MB L3 cache, allows the processor to handle the game's physics, AI, and game logic calculations without impeding the GPU's frame output.

Benchmark data for the Ryzen 7 5800XT shows strong multi-threaded performance, with a 3dmark_max_threads score of 7680 and a cinebench_r23_multicore score of 23794. The single-thread performance, measured at 959 in 3dmark_single_thread and 3359 in cinebench_r23_singlecore, indicates that the processor can handle the primary game thread efficiently. The passmark_multithread score of 27988 further confirms the CPU's ability to manage multiple concurrent workloads, which is essential for maintaining consistent frame times in Doom's intense combat scenarios.

The CPU's memory support for DDR4 with a dual-channel configuration and 51.2 GB/s bandwidth ensures that data can flow between the processor and system memory without creating a bottleneck. The 7 nm process node and 4,150 million transistors on a 74 mm² die contribute to the processor's efficiency, while the 105 W TDP indicates that power delivery is adequate for sustained performance. The data shows that at 1080p Low where the GPU workload is lighter, the system still achieves 369.4 FPS, suggesting that the CPU can keep up with even the most demanding frame rate scenarios.

Resolution Scaling

The measured FPS data across 1080p, 1440p, and 4K resolutions reveals how the system's performance scales with increasing pixel counts, providing insight into which component becomes the limiting factor at each resolution. From 1080p to 1440p, the average frame rate drops by approximately 25-30% depending on the settings preset. For example, at High settings, the FPS decreases from 326.6 at 1080p to 213.7 at 1440p, a reduction of 112.9 FPS or 34.6%. This substantial drop indicates that the GPU is becoming more heavily burdened as the pixel count increases.

The scaling from 1440p to 4K shows an even more pronounced impact on frame rates. At High settings, the FPS drops from 213.7 at 1440p to 114.7 at 4K, a reduction of 99.0 FPS or 46.3%. This pattern holds across all settings presets, with the Low setting experiencing a 45.9% drop from 288.8 FPS to 156.3 FPS, and the Ultra setting seeing a 44.3% reduction from 171.9 FPS to 95.7 FPS. The consistent percentage drops across settings suggest that resolution scaling affects the GPU uniformly, regardless of the graphics preset.

The data indicates that the GPU is the primary limiting component as resolution increases, since the CPU's workload remains relatively constant while the GPU must render significantly more pixels. At 4K, the GPU is rendering 3840x2160 pixels, which is 2.25 times the pixel count of 1920x1080, and the frame rate reductions reflect this increased workload. The fact that the system still maintains over 95 FPS at 4K Ultra demonstrates that the RTX 4090 has sufficient performance headroom, while the Ryzen 7 5800XT provides enough CPU throughput to avoid introducing a bottleneck at lower resolutions. At 1080p, where the GPU is less stressed, the frame rates above 270 FPS indicate that the CPU's single-thread performance and cache architecture are sufficient to support very high refresh rate gaming.
