Doom

The AMD Ryzen 5 7400F paired with the AMD Radeon RX 6600 delivers a remarkably consistent experience in Doom, scaling predictably across resolutions and settings. The key takeaway from the data is that this combination is heavily GPU-bound: frame rates scale almost perfectly with the rendering load, which means users can reliably use resolution as their primary lever for performance tuning.

Resolution Scaling

The measured FPS data shows a textbook example of GPU-bound scaling. At 1080p High settings, the combo produces 129 FPS. Moving to 1440p High drops performance to 84 FPS, a 35% reduction in frame rate for a 77% increase in pixel count. At 4K High, the system delivers 45 FPS, which is 65% lower than the 1080p result. This near-linear scaling with pixel count confirms the RX 6600 is the limiting component; the Ryzen 5 7400F is clearly not constraining performance at any resolution.

The Low settings preset tells the same story with even higher absolute numbers. At 1080p Low, the system hits 176 FPS. At 1440p Low, it produces 114 FPS, and at 4K Low, it manages 62 FPS. The scaling from 1080p to 4K Low is a 65% drop, identical to the High preset's reduction. This consistency across presets is strong evidence that the CPU is never the bottleneck, because if it were, the gap between resolutions would compress as the GPU becomes less stressed.

Medium settings reveal the same pattern with available minimum and maximum frame data. At 1080p Medium, the average is 153 FPS with a minimum of 130 and maximum of 176. At 1440p Medium, the average falls to 99 FPS with a range of 84 to 114. The 4K Medium result shows 54 FPS average with a 46 to 62 range. The min-to-max spread stays proportionally tight across resolutions, indicating stable frame delivery without severe dips that would suggest CPU hitches.

Ultra settings push the system hardest, but the scaling remains predictable. The 1080p Ultra average is 106 FPS, which is 38% below the Low preset at the same resolution. At 1440p Ultra, the system produces 68 FPS, and at 4K Ultra, it falls to 37 FPS. The 4K Ultra result is the only point where the combination dips below a playable threshold, suggesting this preset is only suitable for users who prioritize visual fidelity over smoothness.

The data strongly indicates that the Ryzen 5 7400F's six cores and twelve threads with a 3.70 GHz base and 4.70 GHz boost clock are more than sufficient for Doom's engine. The 32 MB of shared L3 cache and DDR5 memory support provide ample headroom for the game's data streaming. Users should treat resolution as their primary performance control, with settings adjustments providing secondary tuning.

How This Combo Ranks

The combination of the AMD Ryzen 5 7400F and AMD Radeon RX 6600 ranks 2255 out of 2930 tested combos in Doom. This places it in the 23rd percentile of all system pairings, meaning roughly three-quarters of tested combinations deliver higher average frame rates in this title. However, this ranking must be understood in context: the database includes many high-end multi-GPU and flagship configurations that dramatically skew the distribution.

The CPU component of this combo is comparatively strong. The Ryzen 5 7400F sits in the 83rd percentile among all CPUs, which indicates it is well above the median processor. Its average benchmark score of 32750 places it within 0.1% of the Intel Core i5-14600T and 0.2% of the Intel Core Ultra 7 155H. It also edges out the AMD Ryzen 7 PRO 6850H by 0.2% and the AMD Ryzen AI 7 PRO 360 by 0.3%. This suggests the processor is not the weak link in this pairing.

The GPU is the more modest performer. The RX 6600 sits in the 63rd percentile among all GPUs, with an average benchmark score of 19036. Its nearest rivals show how tightly packed this segment is: the NVIDIA Quadro K6000 matches it exactly at 0.0% delta, the NVIDIA GeForce RTX 4050 Mobile is 0.1% faster, and the NVIDIA Tesla K20m is 0.3% faster. The NVIDIA RTX 2000 Ada Generation is 0.4% slower. This clustering means the RX 6600's performance is representative of a broad mid-range tier.

The gap between the CPU's 83rd percentile and the GPU's 63rd percentile explains the combo's overall 23rd percentile ranking in Doom. The game is clearly GPU-limited, so the RX 6600's relative position among GPUs matters more than the CPU's strength. Users should interpret the 2255 rank not as a poor showing, but as an accurate reflection of what a mid-range GPU can achieve in a demanding first-person shooter.

Settings Recommendations

For users targeting 1080p, the High preset at 129 FPS is the optimal balance. It provides a 23 FPS improvement over Ultra while sacrificing only the highest visual details. The Low preset at 176 FPS is excessive for most displays, though it would benefit users with 144Hz or higher refresh rate monitors. The Medium preset at 153 FPS offers a middle ground, but the jump from High to Medium is only 24 FPS, making High the more visually appealing choice.

At 1440p, the High preset at 84 FPS is recommended for smooth gameplay. The Medium preset at 99 FPS provides a 15 FPS improvement, which may be preferable for users who prioritize frame rate over visual quality. The Ultra preset at 68 FPS remains playable but approaches the threshold where fast motion becomes less clear. The Low preset at 114 FPS is available for competitive play, but the visual degradation is noticeable at this resolution.

At 4K, the Low preset at 62 FPS is the only option that consistently exceeds 60 FPS. The Medium preset at 54 FPS is playable but may exhibit occasional dips to 46 FPS. High and Ultra presets at 45 and 37 FPS respectively are not recommended for action-heavy gameplay, as the frame rate drops below the standard acceptable range.

The data suggests that users should prioritize resolution over preset quality. A 1440p High experience at 84 FPS is superior to a 4K Low experience at 62 FPS in terms of both visual clarity and smoothness. Similarly, 1080p Ultra at 106 FPS beats 1440p Low at 114 FPS in overall quality, though the frame rate difference is minimal. The Medium preset offers the best of both worlds at 1080p and 1440p, providing high frame rates with moderate visual enhancements.

CPU Role

The AMD Ryzen 5 7400F is a six-core, twelve-thread processor based on the Zen 4 Raphael architecture, manufactured on a 5 nm process by TSMC. Its base clock is 3.70 GHz with a boost clock of 4.70 GHz, and it carries a 65 W TDP. The CPU features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache, totaling a robust cache hierarchy for game workloads.

In Doom, the CPU's role is clearly secondary to the GPU. The frame rate scaling from 1080p to 4K shows no signs of CPU limitation, as the percentage drop matches the pixel count increase exactly. If the CPU were a bottleneck, the higher resolutions would show a compressed performance gap because the GPU would be waiting on the processor. The data shows no such compression.

The CPU's benchmark results support its adequacy. The Cinebench R23 multicore score of 21765 and single-core score of 3072 indicate strong processing capability. The Passmark multithread score of 25645 and single-thread score of 3689 confirm balanced performance. The CPU's 83rd percentile ranking among all CPUs means it outperforms the vast majority of processors in general workloads, and Doom's engine does not present an unusual demand.

The 32 MB of shared L3 cache is particularly relevant for gaming. Doom's levels stream large amounts of texture and geometry data, and the generous cache helps reduce memory latency. The DDR5 memory support with dual-channel configuration provides 83.2 GB/s of bandwidth, which is ample for this game's requirements. The CPU's PCIe Gen 5 support with 24 lanes ensures the GPU has a fast connection, though the RX 6600 uses PCIe 4.0 x8.

The nearest CPU rivals all show similar performance levels. The Intel Core i5-14600T is 0.1% faster, the Intel Core Ultra 7 155H is 0.2% faster, and the AMD Ryzen AI 7 PRO 360 is 0.3% faster. The AMD Ryzen 7 PRO 6850H is 0.2% slower. This tight grouping means the 7400F is well-positioned in its performance tier, and any of these processors would yield nearly identical Doom results when paired with the RX 6600.

The practical conclusion is that the Ryzen 5 7400F provides more than enough CPU headroom for this GPU in Doom. Users who upgrade the GPU in the future will find the CPU capable of supporting significantly faster graphics cards. The processor's 12 threads and high boost clock ensure smooth frame delivery even in scenes with many enemies or complex physics calculations, though the measured data shows the GPU is always the limiting factor.
