Doom

The AMD Ryzen 5 7400F paired with the AMD Radeon RX 7900 XTX delivers a formidable performance profile in Doom, with the data showing a system that scales predictably across resolutions and settings. The measured frame rates indicate a configuration that is heavily GPU-bound at higher resolutions, while the CPU’s strong single-threaded capabilities ensure the system never becomes the primary bottleneck, even at 1080p. This analysis examines the measured FPS data, component roles, and ranking within the broader benchmark database.

Resolution Scaling

The measured FPS data for this combo shows a clear and consistent scaling pattern as resolution increases. At 1080p with Low settings, the system achieves an average of 366 FPS. Moving to 1440p Low reduces the average to 237 FPS, a drop of approximately 35%. At 4K Low, the average falls to 128 FPS, which is another reduction of roughly 46% from the 1440p figure. This steep decline from 1080p to 4K indicates that the rendering load is scaling heavily with pixel count, which is characteristic of a GPU-bound scenario.

The scaling pattern becomes even more telling when examining the High preset. The system delivers 269 FPS at 1080p, 174 FPS at 1440p, and 94 FPS at 4K. The percentage drop from 1080p to 1440p is about 35%, and from 1440p to 4K is about 46%. This near-identical scaling ratio across different presets suggests that the limiting factor is consistently the GPU’s ability to fill pixels, rather than any CPU-imposed constraint. If the CPU were the bottleneck, we would expect to see a smaller performance delta between resolutions, as the CPU workload would remain relatively constant while the GPU load increases.

The data shows that at 4K Ultra, the average FPS drops to 77, while at 1080p Ultra it is 220. This represents a 65% reduction in performance from the lowest tested resolution to the highest. Such a significant drop is typical for a game like Doom that is well-optimized but still demands substantial GPU resources at higher resolutions. The minimum FPS figures, available only for the Medium preset, further corroborate this trend: at 4K Medium the minimum is 95 FPS, at 1440p Medium it is 176 FPS, and at 1080p Medium it is 271 FPS. The gap between average and minimum FPS remains relatively stable, indicating consistent frame pacing rather than sudden stutters, which would suggest a CPU or memory issue.

Based on this evidence, the limiting component in this configuration is the GPU, especially as resolution increases. The RX 7900 XTX with its 24 GB of VRAM and 960.0 GB/s bandwidth is being pushed to its limits at 4K, but it still maintains playable frame rates above 94 FPS on High settings. The scaling from 1440p to 4K is steeper than from 1080p to 1440p, which aligns with the quadratic increase in pixel count (1440p has 3.7 million pixels, while 4K has 8.3 million). The CPU’s role becomes more prominent at lower resolutions, but even at 1080p Low with 366 FPS, the system does not appear to hit a hard CPU ceiling, as the frame rates continue to scale with GPU load.

How This Combo Ranks

Within the benchmark database, this specific combination of the AMD Ryzen 5 7400F and AMD Radeon RX 7900 XTX ranks 362nd out of 2930 tested combos for Doom. This places the configuration in the top 12.4% of all tested systems, which is a strong result given the broad spectrum of hardware combinations in the database. The rank reflects the synergy between the CPU and GPU, where the Ryzen 5 7400F provides sufficient processing power to feed the high-end Radeon GPU without creating a significant bottleneck.

The CPU alone sits in the 83rd percentile of all CPUs tested, based on its average benchmark score of 32750. Its nearest rivals include the Intel Core i5-14600T with an average score of 32707 (0.1% higher), the AMD Ryzen 7 PRO 6850H with a score of 32812 (0.2% lower), and the AMD Ryzen AI 7 PRO 360 with a score of 32662 (0.3% higher). These deltas are marginal, indicating that the Ryzen 5 7400F is competitively positioned within its performance class, though it does not dominate its immediate peers.

The GPU, on the other hand, has a percentile rank of 64 among all GPUs, with an average benchmark score of 19410. Its nearest rivals are notably older or lower-tier cards, such as the NVIDIA GeForce GTX 1060 3 GB (0.4% higher score) and the NVIDIA TITAN Xp (1.2% lower score). This comparison is somewhat misleading in the context of Doom, as the measured FPS data shows the RX 7900 XTX performing exceptionally well, but the aggregate benchmark score reflects a broader range of workloads where the GPU may not excel as consistently.

The combo rank of 362 out of 2930 suggests that while the individual components are strong, there are many other combinations that outperform this pairing in Doom. This is likely due to the fact that the RX 7900 XTX, despite its high raw performance, is paired with a mid-range CPU that, while capable, does not match the top-tier processors in the database. The rank indicates that for Doom, the system is well-balanced but not at the absolute peak of performance, as higher-end CPUs could potentially extract slightly more FPS at lower resolutions.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, manufactured on a 5 nm process by TSMC. It has a base clock of 3.70 GHz and a boost clock of 4.70 GHz, with a TDP of 65 W. The CPU features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and a shared 32 MB L3 cache. It supports DDR5 memory with a dual-channel bus, providing a theoretical memory bandwidth of 83.2 GB/s.

In the context of Doom, the CPU’s role is primarily to handle game logic, physics, and draw call submission. The game is known for its id Tech engine, which scales well across multiple cores, but the single-threaded performance is often the more critical factor for achieving high frame rates. The Ryzen 5 7400F’s boost clock of 4.70 GHz, combined with a Cinebench R23 single-core score of 3072, demonstrates strong single-threaded capability. This is reflected in the measured FPS at 1080p, where the system achieves 366 FPS on Low settings, indicating that the CPU is not a limiting factor at lower resolutions.

The multi-threaded performance, as evidenced by a Cinebench R23 multi-core score of 21765, provides ample headroom for background tasks and streaming, but for Doom, the 6 cores and 12 threads are more than sufficient. The data shows that at 4K Ultra, the average FPS drops to 77, which is a 79% reduction from the 1080p Low result. This dramatic drop is not due to CPU limitations but rather the GPU’s inability to maintain frame rates at higher resolutions. The CPU’s performance in PassMark single-thread tests (3689) and multi-thread tests (25645) further supports the notion that it can keep up with the GPU’s output, as the system does not exhibit any signs of CPU-induced stuttering or frame drops.

The CPU’s 32 MB of shared L3 cache is another factor that benefits Doom, as the game’s data sets can be partially cached within the CPU, reducing memory latency. The 83.2 GB/s memory bandwidth is also adequate for the game’s requirements, especially when paired with DDR5 memory. Overall, the Ryzen 5 7400F serves as a solid foundation for this GPU, ensuring that the system remains balanced across all tested resolutions.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system’s performance across three resolutions and four settings presets. At 1920x1080, the system delivers an average of 366 FPS on Low, 319 FPS on Medium, 269 FPS on High, and 220 FPS on Ultra. The Medium preset also records a minimum FPS of 271 and a maximum of 367, indicating tight frame pacing and minimal variance. The progression from Low to Ultra shows a 40% reduction in average FPS, which is a moderate penalty for increased visual fidelity.

At 2560x1440, the averages are 237 FPS on Low, 206 FPS on Medium, 174 FPS on High, and 143 FPS on Ultra. The Medium preset’s minimum and maximum are 176 and 237 FPS, respectively. The drop from 1080p to 1440p is significant, with the Ultra preset losing about 35% of its performance (220 to 143 FPS). This suggests that the GPU is starting to become the limiting factor at this resolution, though the frame rates remain exceptionally high for a 1440p experience.

At 3840x2160, the averages drop to 128 FPS on Low, 112 FPS on Medium, 94 FPS on High, and 77 FPS on Ultra. The Medium preset shows a minimum of 95 FPS and a maximum of 129 FPS. The transition from 1440p to 4K yields a further 46% reduction on Ultra (143 to 77 FPS), highlighting the significant GPU workload at 4K. Despite this, even the lowest average of 77 FPS on Ultra is playable, and the High preset at 94 FPS offers a smoother experience without a major visual compromise.

The data reveals that the system is capable of running Doom at 4K with playable frame rates across all settings, with the Low preset achieving 128 FPS and the Ultra preset at 77 FPS. For users prioritizing high refresh rates, the 1080p and 1440p resolutions offer ample headroom, with even the Ultra preset exceeding 140 FPS at 1440p. The Medium preset consistently provides the best balance of performance and visual quality, with minimum FPS figures that are well above 60 FPS at all resolutions.

GPU Role

The AMD Radeon RX 7900 XTX is the flagship GPU in the Radeon RX 7000 series, based on the RDNA 3.0 architecture and codenamed Plum Bonito. It features 6144 shading units, 384 texture mapping units, and 192 raster operation units, along with 96 ray tracing cores. The GPU has a base clock of 1929 MHz, a game clock of 2365 MHz, and a boost clock of 2498 MHz. It is equipped with 24 GB of GDDR6 memory on a 384-bit bus, providing a memory bandwidth of 960.0 GB/s.

In Doom, the GPU is the dominant component, and its 24 GB of VRAM ensures that even at 4K with Ultra settings, there is no risk of memory capacity being exceeded. The game is not particularly demanding on VRAM, but the high bandwidth of 960.0 GB/s allows for efficient texture streaming and high-resolution asset loading. The GPU’s FP32 performance of 61.39 TFLOPS and texture rate of 959.2 GTexel/s are more than sufficient for the game’s rendering requirements.

The measured FPS data shows that the RX 7900 XTX performs admirably, with the system achieving 366 FPS at 1080p Low and 77 FPS at 4K Ultra. The GPU’s performance scales predictably with resolution, and the lack of any significant frame drops (as evidenced by the Medium preset’s minimum FPS) suggests that the GPU is stable under load. The 64th percentile ranking among all GPUs is somewhat conservative, as the RX 7900 XTX’s high-end specifications are not always reflected in aggregate benchmarks, but in Doom specifically, it demonstrates top-tier performance.

The GPU’s power requirements are substantial, with a TDP of 355 W and a suggested PSU of 750 W, but the data does not indicate any thermal throttling or performance degradation. The dual-slot design and 2x 8-pin power connectors are standard for this class of GPU. The 96 ray tracing cores are not heavily utilized in Doom (which does not require RT), but they do not detract from performance either. Overall, the RX 7900 XTX is the primary driver of the system’s high frame rates, and its capabilities are well-matched to the Ryzen 5 7400F.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this configuration depend on the user’s resolution and refresh rate priorities. At 4K, the High preset offers the best balance, delivering an average of 94 FPS, which is suitable for a 60 Hz or 120 Hz display. The Ultra preset at 77 FPS is still playable, but the 18% improvement in average FPS from Ultra to High (77 to 94) comes with a minimal visual penalty, making High the recommended choice for a smoother experience. The Low preset at 128 FPS is ideal for competitive play, but it sacrifices significant visual quality.

At 1440p, the Ultra preset achieves 143 FPS, which is excellent for high refresh rate monitors (144 Hz or higher). The Medium preset at 206 FPS provides even more headroom, but the visual difference between Medium and Ultra is noticeable in Doom’s detailed environments. For users with 144 Hz displays, the Ultra preset is recommended to maximize visual fidelity while still maintaining a frame rate above the refresh rate. The High preset at 174 FPS is a good middle ground, but it does not offer a significant advantage over Ultra in terms of smoothness.

At 1080p, all settings exceed 220 FPS, which is beyond the refresh rate of most monitors (typically 144 Hz or 240 Hz). In this scenario, the Ultra preset at 220 FPS is the clear recommendation, as it provides the best visual quality without any risk of dropping below the monitor’s refresh rate. The Low preset at 366 FPS is only beneficial for users with very high refresh rate displays (360 Hz or higher), where the extra frames could provide a competitive edge.

For the majority of users, the Medium preset offers the most consistent experience across all resolutions, with minimum FPS figures of 271, 176, and 95 at 1080p, 1440p, and 4K, respectively. This preset ensures that the frame rate rarely dips below the average, providing a stable and enjoyable gaming experience. The data suggests that the system is versatile enough to handle any settings combination, but the Medium preset is the safest recommendation for a balanced experience.
