Doom

The AMD Ryzen 5 7400F paired with the AMD Radeon RX 7900 XT delivers a remarkably consistent performance profile in Doom, with frame rates that scale predictably across resolutions and settings. The measured data reveals a system that is heavily GPU-bound at higher resolutions but retains enough CPU headroom to push exceptional numbers at 1080p, making this combo a versatile option for both competitive and high-fidelity play.

Resolution Scaling

The frame rate progression from 1080p to 4K clearly illustrates where the bottleneck shifts. At 1920x1080 with Ultra settings, the combo produces an average of 203 FPS. Moving to 2560x1440 at the same preset drops this to 132 FPS, a reduction of 71 FPS or roughly 35%. The jump to 3840x2160 at Ultra yields 71 FPS average, which is another 61 FPS drop from 1440p, representing a 46% decrease. This steep decline at 4K strongly indicates that the Radeon RX 7900 XT’s rendering capabilities are the limiting factor at the highest resolution.

At the Low preset, the scaling pattern is even more telling. The 1080p Low setting achieves 338 FPS average, while 1440p Low still manages a very high 219 FPS, and 4K Low drops to 119 FPS. The gap between 1080p and 1440p at Low settings is 119 FPS, but the gap between 1440p and 4K is 100 FPS. This suggests that even at the lowest graphical load, the GPU’s pixel throughput at 4K becomes the primary constraint, as the CPU is clearly capable of feeding frames at a much higher rate.

The Medium preset shows a similar trend with averages of 295 FPS at 1080p, 191 FPS at 1440p, and 103 FPS at 4K. Interestingly, the delta between 1080p and 1440p is 104 FPS, while the delta between 1440p and 4K is 88 FPS. This pattern across all presets confirms that resolution scaling is nearly linear in terms of pixel count, but the absolute performance ceiling at 4K is firmly set by the GPU. The data implies that for 4K gaming, the Ryzen 5 7400F is not the limiting component; the RX 7900 XT’s output is what defines the experience.

GPU Role

The AMD Radeon RX 7900 XT is the star of this show, and its specifications explain the measured results. It features 20 GB of GDDR6 memory on a 320-bit bus, delivering 800.0 GB/s of bandwidth. This massive memory pool and bandwidth are crucial for Doom’s texture-heavy environments, ensuring that at 4K Ultra, the card never runs out of memory or bandwidth headroom, as evidenced by the playable 71 FPS average. The GPU’s boost clock of 2394 MHz and game clock of 2025 MHz provide a solid foundation for the observed frame rates. With 5376 shading units and 192 ROPs, the card’s pixel rate of 459.6 GPixel/s and texture rate of 804.4 GTexel/s directly translate to the high fill rates required for smooth 4K rendering.

The GPU’s performance percentile of 55 versus all GPUs places it in the mid-upper range, but its nearest rivals in the benchmark database are surprising. The AMD Radeon 660M, an integrated GPU, shows an average score of 13812 with a deltaPct of -0.5, while the NVIDIA RTX A2000 Mobile shows 13821 with a -0.5 deltaPct. This data point is curious, as the RX 7900 XT’s raw compute power in Doom’s measured FPS vastly exceeds what those rivals could achieve. The average benchmark score of 13745 for the RX 7900 XT is skewed by other tests, but in this specific game, the real-world FPS numbers tell the true story. The gap between the RX 7900 XT and its nearest rivals in the database is minimal (within 1.5%), yet in Doom, the performance is clearly at a high-end level.

The 4K Medium result shows a min FPS of 88 and max of 119, with an average of 103. This narrow frame time variance indicates the GPU is delivering consistent frames without major spikes. The 4K Low average of 119 FPS is particularly notable, showing that even at the lowest settings, the GPU is not fully unshackled from its own limits. The data suggests that the RX 7900 XT is optimized for high-resolution gaming, with its 20 GB VRAM ensuring no texture pop-in or stutter at 4K, which is a common issue with lower-memory cards.

CPU Role

The AMD Ryzen 5 7400F brings 6 cores and 12 threads based on the Zen 4 architecture, running at a base clock of 3.70 GHz and a boost clock of 4.70 GHz. Its 32 MB of shared L3 cache is ample for Doom’s engine, which typically doesn’t require massive cache hierarchies. The CPU’s benchmark results show a Cinebench R23 multi-core score of 21765 and a single-core score of 3072, indicating strong per-thread performance that is essential for high-FPS gaming. The PassMark single-thread score of 3689 and multithread score of 25645 further confirm that this CPU is no slouch.

The CPU’s percentile versus all CPUs is 83, placing it in the top quartile. Its nearest rivals include the Intel Core i5-14600T with a deltaPct of 0.1 and the AMD Ryzen 7 PRO 6850H with a deltaPct of -0.2. These rivals are all within 0.3% of the 7400F’s average benchmark score of 32750, indicating that in synthetic tests, they are nearly identical. However, in Doom, the 7400F’s high boost clock and Zen 4 IPC shine. At 1080p Low, the combo hits 338 FPS average, which is a clear indication that the CPU can handle very high frame rates without bottlenecking the GPU.

The 1080p Medium result shows a min FPS of 251 and max of 339, with an average of 295. This wide range suggests that the CPU is capable of pushing frames well above 300, but the GPU’s workload at Medium settings introduces some variance. The 4K results show that the CPU is essentially idle in terms of constraint, as the GPU is the clear limiter. The data implies that for 1080p competitive play, the 7400F provides more than enough headroom, while at 4K, its role diminishes to simply feeding the GPU without stuttering. The CPU’s 65 W TDP and 5 nm process node make it an efficient choice, though power draw is not a primary factor in these frame rate measurements.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across all settings and resolutions. At 1920x1080, the Low preset delivers an average of 338 FPS, which is the highest recorded value in the dataset. The Medium preset at 1080p shows an average of 295 FPS with a min of 251 and max of 339, indicating that the max FPS is nearly identical to the Low preset’s average. High at 1080p drops to 249 FPS average, while Ultra is significantly lower at 203 FPS. This 135 FPS difference between Low and Ultra at 1080p illustrates the GPU load scaling with visual fidelity.

Moving to 2560x1440, the Low preset averages 219 FPS, which is still exceptionally high for 1440p. Medium at 1440p shows 191 FPS average with a min of 162 and max of 219, where the max matches the Low average. High at 1440p averages 161 FPS, and Ultra drops to 132 FPS. The pattern shows that each preset tier at 1440p reduces performance by roughly 20-30 FPS, which is a reasonable cost for the visual improvements. The 1440p Medium min FPS of 162 is still well above 144 Hz refresh rates, making this combo ideal for high-refresh 1440p monitors.

At 3840x2160, the performance takes a more significant hit. Low averages 119 FPS, which is playable but not ultra-smooth for competitive play. Medium averages 103 FPS with a min of 88 and max of 119, showing that even the minimum frame rate is above 60 FPS. High averages 87 FPS, and Ultra averages 71 FPS. The 4K Ultra result of 71 FPS is above the 60 FPS threshold for console-like smoothness but falls short of high-refresh 4K displays. The data shows a clear hierarchy: 4K is viable for all settings, but Ultra at 4K requires a tolerance for lower frame rates.

How This Combo Ranks

In the database of tested combos for Doom, this configuration ranks 533 out of 2930 tested combinations. This places it in the top 18% of all combos tested for this game. The rank is impressive given that the RX 7900 XT’s percentile versus all GPUs is only 55, and the CPU’s percentile is 83. The combination of a top-quartile CPU with a mid-range GPU (by percentile) yields a high rank because Doom is well-optimized and the CPU helps maximize the GPU’s potential.

The combo rank suggests that many other combinations with higher-priced GPUs may not perform as well in Doom due to CPU bottlenecks or driver issues. The data implies that this pairing is particularly well-balanced for this title, with the CPU’s strong single-core performance (PassMark single-thread of 3689) complementing the GPU’s high memory bandwidth. The 533rd rank out of 2930 means there are 532 combos that perform better, but this still places the setup well above average. The fact that the RX 7900 XT’s nearest rivals in the database are vastly different cards (integrated and mobile GPUs) suggests that the benchmark aggregation may not fully capture gaming performance, but the in-game rank is what matters for real-world use.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1080p displays with 240 Hz or higher refresh rates, the High preset at 249 FPS average is the best choice, as it offers excellent visual quality while staying above 240 FPS. The Ultra preset at 203 FPS is also viable for 144 Hz monitors, providing the highest fidelity without dipping below the refresh threshold. For 1080p, the Low preset’s 338 FPS is unnecessary unless chasing maximum frame rates on 360 Hz panels.

At 1440p, the Medium preset with 191 FPS average is the sweet spot for high-refresh monitors, as it provides a significant visual upgrade over Low while maintaining frame rates well above 165 Hz. The High preset at 161 FPS is also excellent for 144 Hz displays, offering better textures and effects. Ultra at 1440p with 132 FPS is playable but may not fully saturate a 144 Hz display, so it is only recommended for those who prioritize visuals over maximum smoothness. The 1440p Low preset at 219 FPS is overkill for most monitors and sacrifices too much visual fidelity.

For 4K, the Medium preset with 103 FPS average and a min of 88 FPS is the recommended choice, as it provides a balanced experience with no frame drops below 60 FPS. The Low preset at 119 FPS is for those who want higher frame rates but can tolerate lower textures. High at 87 FPS and Ultra at 71 FPS are both viable for 60 Hz 4K displays, with Ultra offering the best visual experience at the cost of lower average frame rates. Given the data, Medium at 4K offers the best combination of visual quality and performance, ensuring smooth gameplay with minimal stutter.
