How This Combo Ranks

The combination rank of 110 out of 3712 tested combos places this system firmly in the upper echelon of Doom performance. This rank reflects a system that is capable of running the game at maximum settings with massive headroom above the 60 FPS threshold. The percentile standing of the RTX 5090 alone is 92, meaning it outperforms 92% of all GPUs in the benchmark database; the i5-13400F sits at the 77th percentile among all CPUs.

The measured FPS results confirm this ranking. At 1080p, the lowest preset tested (Ultra) still produces 275.1 FPS, which is higher than the 4K Ultra result of 96 FPS. This spread shows that the system has enough performance to handle the game at high refresh rates even at 4K, and at lower resolutions, the performance is effectively untapped. The 1440p results show a similar pattern, with Ultra hitting 180.1 FPS and Low reaching 295.9 FPS.

The rank of 110 is notable given the hardware involved. The RTX 5090 is a flagship GPU, and the i5-13400F is a capable mid-range CPU; the combination places the system ahead of the vast majority of tested configurations. The data indicates that for Doom specifically, this pairing has no weak points—every resolution and preset tested is comfortably playable.

CPU and GPU Roles

The benchmark data reveals that the RTX 5090 is the dominant component in this pairing, but the i5-13400F provides sufficient support to avoid becoming a bottleneck. At 3840x2160, the FPS drops from 158.6 at Low to 96 at Ultra, a reduction of 62.6 FPS as the GPU workload increases. This scaling shows the GPU is the limiting factor at 4K, as raising the preset increases the pixel and shading workload.

At 2560x1440, the same pattern appears but with higher absolute numbers. Low settings produce 295.9 FPS, while Ultra produces 180.1 FPS—a difference of 115.8 FPS. The gap between presets widens at 1440p compared to 4K, which indicates the GPU has more headroom to express its capabilities when the resolution is lower. The CPU still keeps up, as the minimum FPS at 1440p Ultra is 180.1, which is far above any CPU-limited threshold.

At 1920x1080, the FPS figures are the highest of all: 382 at Low, 365.7 at Medium, 340.7 at High, and 275.1 at Ultra. The difference between Low and Ultra is 106.9 FPS, which is similar to the spread at 1440p. The fact that 1080p Low (382 FPS) is only 86.1 FPS higher than 1440p Low (295.9 FPS) suggests that at 1080p, the CPU may start to become a more significant factor, as the GPU is capable of very high frame rates but the frame times are still consistent.

The CPU's role is visible in the benchmark scores: the i5-13400F achieves a single-thread score of 960 in 3dmark and 3191 in Cinebench R23 single-core, which are strong results for a 13th-gen Core i5. Its 16 threads produce a Cinebench R23 multicore score of 22604, ensuring that even in CPU-heavy scenes, the system does not drop below the measured FPS figures. For Doom, which is a fast-paced FPS, the CPU's high single-thread performance is sufficient to feed the RTX 5090 at all tested settings.

The Verdict

This system can run Doom at every resolution and preset tested, with massive headroom above the 60 FPS playability threshold. The verdict by resolution is clear:

• 3840x2160: All four presets are playable. The best settings are Ultra, which delivers an average of 96 FPS. Even the most demanding preset stays well above 60 FPS.
• 2560x1440: All four presets are playable. The best settings are Ultra, which delivers an average of 180.1 FPS. This is triple the playability threshold and suitable for high-refresh-rate monitors.
• 1920x1080: All four presets are playable. The best settings are Ultra, which delivers an average of 275.1 FPS. This is over four times the playability threshold, making the system suitable for 240Hz or higher displays.

The data shows that the system never drops below 96 FPS in any tested configuration. For a game like Doom, which benefits from high frame rates, this combination provides an exceptional experience. The weakest point—4K Ultra at 96 FPS—is still 60% above the threshold, leaving no practical reason to reduce settings unless aiming for very high refresh rates at 4K.

Similar Performance Alternatives

The nearest rivals for the RTX 5090 in average benchmark score are the NVIDIA Tesla P100 PCIe 16 GB (0.3% behind), the NVIDIA Tesla P100 PCIe 12 GB (0.6% behind), and the AMD Radeon RX 6850M XT (1.1% behind). These GPUs would produce similar raw performance in synthetic benchmarks, though the Tesla parts are data-center oriented and the RX 6850M XT is a mobile part, so real-world gaming results may differ. The AMD Radeon Pro Vega 64X is 1.4% ahead, making it a slightly faster rival in average score.

For the CPU, the nearest rivals are the AMD Ryzen 9 6900HS (0% difference), the Intel Core 5 120 (0.3% behind), and the AMD Ryzen 5 5600X3D (0.3% behind). The AMD Ryzen 7 6800H is 0.4% ahead. These CPUs have nearly identical average benchmark scores to the i5-13400F, meaning they would provide similar CPU-side performance in Doom. The Ryzen 5 5600X3D is particularly relevant for gaming due to its 3D V-Cache, though the benchmark scores suggest the i5-13400F is already well-matched.

If you are considering alternatives to this specific combo, swapping the i5-13400F for any of these nearest rivals would result in negligible performance changes in Doom, as the benchmark scores are within 0.4% of each other. Similarly, the RTX 5090's nearest rivals would offer comparable GPU performance, but the RTX 5090 is the only consumer-focused GPU in its immediate benchmark neighborhood—the Tesla parts and the mobile RX 6850M XT are not direct retail alternatives for gaming.

Best Settings per Resolution

The most demanding preset that stays at or above 60 FPS at each resolution is the Ultra preset in all cases, based on the tested data:

• 3840x2160: Ultra settings deliver an average of 96 FPS. This is the highest quality preset tested and remains 36 FPS above the 60 FPS threshold. Lower presets provide higher FPS—Medium at 142.8, High at 116.4, and Low at 158.6—but Ultra is the best choice for visual fidelity without risking playability.
• 2560x1440: Ultra settings deliver an average of 180.1 FPS. This is the recommended choice for 1440p, as it offers the full visual experience while maintaining a frame rate that is three times the playability threshold. The next step down, High, produces 218.3 FPS, but the visual difference is not worth the frame rate increase.
• 1920x1080: Ultra settings deliver an average of 275.1 FPS. This is the optimal setting for 1080p, providing the highest quality with frame rates that exceed the refresh rate of most monitors. Low settings produce 382 FPS, which is only useful for competitive play on very high refresh rate displays.

In summary, the Ultra preset is the best choice at every resolution because it always stays above 96 FPS, which is far above the 60 FPS playability threshold. There is no reason to reduce settings for playability; doing so would only be for chasing extremely high frame rates beyond what the Ultra preset already delivers.
