Doom

The AMD Ryzen 7 5800X paired with the NVIDIA GeForce RTX 4090 ranks 52nd out of 1,681 tested combos in Doom, placing it in the top 3.1% of all configurations. This is a dominant position, indicating that this pairing delivers exceptional performance in this title, driven primarily by the RTX 4090's immense graphics horsepower. The data confirms that this combo is geared toward high-refresh-rate 1440p gaming and smooth 4K experiences, rather than being a bottleneck-limited setup.

How This Combo Ranks

The combo’s rank of 52 out of 1,681 represents a top-tier result, placing it ahead of roughly 97% of all tested system pairings. This high percentile is expected given the components involved: the CPU sits at the 84th percentile among all processors, and the GPU is at the 91st percentile among all graphics cards. In Doom, this synergy results in a system that can handle even the most demanding settings without significant compromise. The rank suggests that while there are 51 faster combos, they are likely composed of even more recent flagship hardware, making this pairing a highly capable, but not absolute top-of-the-line, option. The data indicates that the RTX 4090 is the primary driver of this ranking, as the CPU’s performance is sufficient to feed the GPU effectively at all settings and resolutions tested.

GPU Role

The NVIDIA GeForce RTX 4090 is the undisputed star of this configuration, and its specifications explain the measured frame rates. It features 24 GB of GDDR6X memory on a 384-bit bus, providing a massive 1.01 TB/s of memory bandwidth. This is crucial for Doom’s high-resolution textures and fast-paced rendering, ensuring that data is fed to the GPU cores without stuttering. The GPU’s boost clock of 2520 MHz, paired with its 16,384 shading units, allows it to achieve a peak FP32 throughput of 82.58 TFLOPS. The benchmark data confirms its strength, with a passmark G3D score of 38,194. In Doom, this translates directly to the ability to push very high frame rates at 1080p and 1440p, and maintain playable, high-frame-rate performance at 4K, as evidenced by the measured FPS breakdown. The GPU is clearly the limiting factor at 4K Ultra, where even its massive resources are challenged, but it remains fully in control at lower resolutions.

FAQ

Q: Is this combo better suited for 1080p or 4K gaming in Doom?

A: The data shows it excels at both but is more comfortably dominant at lower resolutions. At 1080p Ultra, it achieves 268.5 FPS, while at 4K Ultra, it drops to 92.3 FPS. The 4K performance is still excellent, but the 1080p and 1440p results are more likely to exceed the refresh rate of most high-end monitors.

Q: How much of a performance difference does the Ultra preset make compared to High?

A: The Ultra preset is significantly more demanding. At 4K, moving from High (115.1 FPS) to Ultra (92.3 FPS) results in a 19.8% drop in average frame rate. At 1440p, the drop is from 210 FPS to 176.2 FPS, a 16.1% decrease.

Q: What is the most significant performance bottleneck at 4K resolution?

A: The GPU is the clear limiting factor at 4K. The difference between 4K Low (158 FPS) and 4K Ultra (92.3 FPS) is substantial, showing that the graphics card’s workload scales heavily with settings. The CPU, with its 8 cores and 16 threads, is not the constraint here.

Q: Can this system handle high refresh rate 1440p monitors?

A: Yes, decisively. At 1440p High, the combo produces 210 FPS, and even at the most demanding Ultra preset, it still achieves 176.2 FPS. This is well above the 144Hz and 165Hz refresh rates common on modern gaming monitors.

Q: How does the RTX 4090's benchmark score compare to its nearest rivals?

A: The GPU’s average benchmark score is 66,473. Its closest competitor in the data is the NVIDIA Tesla T4, which has a score of 66,733, a delta of -0.4%. This indicates the RTX 4090's score is within a fraction of a percent of its nearest rival, showing incredibly tight competition at the very top of the performance stack.

Q: Is the CPU's performance a limiting factor in this game?

A: In Doom, the CPU appears sufficient. Its average benchmark score is 27,606, which is 0.3% ahead of the AMD Ryzen 7 5800 and only 0.8% behind the Intel Core i5-12600KF. The consistent FPS gains from 4K to 1080p suggest the GPU is handling the increased load, not the CPU.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across resolutions and settings. At 1920x1080, the combo delivers exceptional results: Low settings produce 363.8 FPS, Medium 346.6 FPS, High 325 FPS, and even the demanding Ultra preset maintains 268.5 FPS. Moving to 2560x1440, the frame rates remain very high, with Low at 289.5 FPS, Medium at 249.9 FPS, High at 210 FPS, and Ultra at 176.2 FPS. At 3840x2160, the GPU begins to feel the pressure, but results are still strong: Low hits 158 FPS, Medium 138 FPS, High 115.1 FPS, and Ultra drops to 92.3 FPS. This data shows a consistent scaling pattern where each step up in settings costs a measurable amount of performance, with the Ultra preset being the most taxing.

Resolution Scaling

The performance scaling from 1080p to 4K clearly identifies the GPU as the primary workload driver. At High settings, the average frame rate drops from 325 FPS at 1080p to 210 FPS at 1440p (a 35.4% decrease), and then to 115.1 FPS at 4K (a further 45.2% decrease from 1440p). This steep decline is characteristic of a GPU-bound scenario. The CPU, with its 8 cores and 16 threads, is not challenged by the increased resolution, as the workload per core does not change significantly with resolution. The data suggests that at 1080p, the system is likely still GPU-bound but with so much headroom that the frame rate is exceptionally high. The limiting component is overwhelmingly the RTX 4090, which is expected given its role in rendering the higher pixel counts.

Settings Recommendations

For the best experience, the data points to a balance between visual fidelity and frame rate. At 4K, the High preset (115.1 FPS) offers a better experience than Ultra (92.3 FPS) because the 19.8% performance gain is likely more valuable than the marginal visual improvement, especially for a fast-paced FPS. At 1440p, the Ultra preset (176.2 FPS) is highly recommended, as it still provides frame rates far above standard 144Hz monitors, making the visual upgrade free. At 1080p, even the Ultra preset (268.5 FPS) is so fast that it is the clear choice. The data suggests that the Ultra preset is the best option for 1080p and 1440p, while High is the more sensible choice for 4K to maintain a higher refresh rate.

CPU Role

The AMD Ryzen 7 5800X, with its 8 cores and 16 threads, plays a supporting but essential role. Its boost clock of 4.70 GHz and 32 MB of L3 cache provide ample processing power for game logic and physics. The benchmark results show it is a strong performer, with a Cinebench R23 multi-core score of 23,571 and a single-core score of 3,327. In Doom, this level of CPU performance is more than adequate, as evidenced by the fact that frame rates scale consistently with GPU load. The data shows that the CPU is not a bottleneck at any resolution, as the FPS differences between settings are fully explained by the GPU’s workload. The 5800X’s performance is closely matched to its nearest rivals, being 0.3% ahead of the AMD Ryzen 7 5800 and only 0.8% behind the Intel Core i5-12600KF, confirming it is a well-balanced partner for the RTX 4090 in this title.
