Doom

The AMD Ryzen 5 7400F and NVIDIA GeForce RTX 5080 combination delivers exceptional performance in Doom, making it a top-tier pairing for this title. With the combo ranking in the 94th percentile (rank 163 out of 2930 tested configurations), this system is clearly positioned for high-refresh-rate gaming. The data shows a platform that can push well beyond 250 FPS at 1080p and remains highly playable even at 4K, though the performance scaling reveals a clear shift in system bottleneck as resolution increases.

Resolution Scaling

The measured FPS data shows a predictable and steep decline as resolution increases, but the curve is notably smooth and consistent across all settings presets. At 1080p with High settings, the system produces 306 FPS average. Moving to 1440p drops that to 198 FPS, a 35% reduction. Jumping to 4K further reduces performance to 107 FPS, which is another 46% drop from the 1440p result. This pattern indicates that the RTX 5080 is becoming the primary limiting factor as pixel count rises.

At the Low settings preset, the scaling story is even more pronounced. The system delivers 385 FPS at 1080p, 269 FPS at 1440p, and 146 FPS at 4K. The percentage drops between resolutions are similar to High settings, but the absolute numbers remain extremely high. This suggests that even at 4K Low, the GPU is still pushing a very playable frame rate, while at 1080p Low the system is clearly CPU-limited, as the GPU has headroom to render far more frames than the processor can feed.

The Medium preset offers a useful middle ground for analyzing the bottleneck. At 1080p Medium, the system hits 363 FPS, which is only slightly below the Low preset's 385 FPS. The gap between Medium and High at 1080p is 57 FPS (363 vs 306), while at 4K that gap narrows to 20 FPS (127 vs 107). This compression of the delta at higher resolutions confirms that the GPU is the limiting factor at 4K, while the CPU has more influence on the 1080p results.

Ultra settings show the most aggressive scaling curve. The system produces 250 FPS at 1080p, 162 FPS at 1440p, and just 88 FPS at 4K. The 4K Ultra result is the only measured configuration that falls below the 100 FPS mark, indicating that this is the point where the RTX 5080's raw compute is fully taxed by Doom's maximum visual fidelity. The gap between Ultra and High at 4K (88 vs 107 FPS) represents a 19 FPS cost for the highest quality preset, which is a significant trade-off.

CPU Role

The AMD Ryzen 5 7400F brings six Zen 4 cores with twelve threads to this matchup, running at a base clock of 3.70 GHz and boosting to 4.70 GHz. The processor's 32 MB of shared L3 cache and dual-channel DDR5 memory support with 83.2 GB/s of bandwidth provide a solid foundation for feeding the RTX 5080. In synthetic benchmarks, the 7400F scores 21,765 in Cinebench R23 multi-core and 3,072 in single-core, placing it in the 83rd percentile among all CPUs with an average benchmark score of 32,750.

The nearest rival data for the 7400F shows a tightly clustered field. The Intel Core i5-14600T scores 32,707 (0.1% faster), the Intel Core Ultra 7 155H scores 32,697 (0.2% faster), and the AMD Ryzen AI 7 PRO 360 scores 32,662 (0.3% faster). Only the AMD Ryzen 7 PRO 6850H trails at 32,812 (-0.2%). This indicates that the 7400F is competitively positioned within its performance class, though the differences are negligible in real-world gaming scenarios.

In Doom specifically, the CPU's role becomes visible when examining the 1080p results. The jump from Low to Medium settings at 1080p only costs 22 FPS (385 to 363), while the jump from Medium to High costs 57 FPS (363 to 306). This non-linear scaling suggests the CPU is near its limit at 1080p Low, as the GPU can render frames faster than the processor can issue draw calls. The 12 threads of the 7400F are sufficient for Doom's engine, which is well-optimized for multi-threaded workloads, but the game's single-thread performance demands are met comfortably by the 4.70 GHz boost clock.

Settings Recommendations

For the best experience per the measured rows, the High preset at 1440p emerges as the sweet spot. It delivers 198 FPS average, which is well above the refresh rate of most high-end monitors, while maintaining the visual quality improvements over Medium. The Medium preset at 1440p offers 235 FPS, which is a 37 FPS improvement, but the visual downgrade may not be worth it for most users. At 4K, the High preset at 107 FPS is the best balance, as it stays above 100 FPS while the Ultra preset drops to 88 FPS.

For competitive play at 1080p, the Low preset at 385 FPS is the clear choice, but the Medium preset at 363 FPS is only 22 FPS slower and provides better visuals. The data suggests that Medium at 1080p is the optimal competitive setting, as the 22 FPS difference is unlikely to be perceptible on most displays, while the visual improvements are noticeable. The High preset at 1080p (306 FPS) still provides an excellent experience for those who prioritize image quality over raw frame rate.

At 4K, the Low preset (146 FPS) is the only configuration that provides a significant margin above 120 FPS. The Medium preset (127 FPS) is still very playable, but the High preset (107 FPS) is the recommended choice for the best balance of visual fidelity and smoothness. The Ultra preset at 88 FPS is only recommended for users with VRR displays who prioritize visual quality above all else, as the 19 FPS drop from High is substantial.
