Doom

This PC configuration, pairing the AMD Ryzen 5 8400F with the NVIDIA GeForce RTX 5090, delivers playable performance at every preset and resolution tested for Doom. The data shows the RTX 5090 is the dominant component, pushing frame rates that far exceed the 60 FPS playable threshold even at 4K Ultra settings. While the Ryzen 5 8400F holds the system back at lower resolutions, the overall experience is overwhelmingly positive, with the GPU ensuring high refresh rate gaming across the board.

Measured FPS Breakdown

The benchmark results for Doom reveal a system that scales predictably with resolution and settings, though the CPU becomes a notable factor at lower resolutions. At 3840x2160, the average frame rates are 118.9 FPS on High settings, 159.3 FPS on Low, 142.5 FPS on Medium, and 97.5 FPS on Ultra. This represents a 61.8 FPS difference between the Low and Ultra presets, indicating that the GPU is the primary bottleneck at 4K, with each settings tier producing a substantial shift in performance.

Dropping to 2560x1440 shows significant headroom, with the average FPS reaching 216.8 on High, 298.3 on Low, 256.6 on Medium, and 176.9 on Ultra. The jump from 4K to 1440p yields roughly an 82% performance improvement on the Ultra preset, moving from 97.5 FPS to 176.9 FPS. The scaling between Low and Ultra at 1440p is 121.4 FPS, which is larger than the 61.8 FPS gap seen at 4K, suggesting that the CPU begins to play a more significant role as resolution decreases.

At 1920x1080, the frame rates become extraordinarily high, with averages of 341.3 FPS on High, 387.4 FPS on Low, 370.7 FPS on Medium, and 278.6 FPS on Ultra. The difference between Low and Ultra narrows to 108.8 FPS, which is less than the 121.4 FPS gap at 1440p. This compression at 1080p indicates that the Ryzen 5 8400F is becoming a limiting factor, preventing the RTX 5090 from fully stretching its legs. The maximum recorded average of 387.4 FPS at 1080p Low suggests the CPU’s single-thread performance, measured at 951 in the 3dmark single thread test and 2943 in Cinebench R23 single-core, is the ceiling for this configuration.

Best Settings per Resolution

The verdict data confirms that all four settings presets are playable at every resolution, meaning the most demanding preset that maintains at least 60 FPS is always Ultra. At 3840x2160, the Ultra preset delivers an average of 97.5 FPS, which is comfortably above the 60 FPS threshold. This makes Ultra the best choice for 4K gaming, as there is no reason to compromise visual quality when the hardware can handle the maximum load.

For 2560x1440, the Ultra preset produces an average of 176.9 FPS, again making it the best settings option. The substantial margin above 60 FPS means users can enable every graphical feature without concern. At 1920x1080, the Ultra preset achieves 278.6 FPS on average, providing an exceptionally smooth experience that would suit high-refresh-rate monitors.

The pattern is consistent across all resolutions: the RTX 5090 is powerful enough that the most demanding preset remains playable, and the limiting factor is never the GPU’s rendering capacity but rather the CPU’s ability to feed it frames at lower resolutions. The data shows that even at 4K Ultra, the system maintains nearly 100 FPS, which is a strong result for a game that is not particularly demanding by modern standards.

CPU and GPU Roles

The benchmark data reveals a clear division of labor between the Ryzen 5 8400F and the RTX 5090, with the GPU dominating at higher resolutions and the CPU becoming more relevant at 1080p. At 3840x2160, the performance scaling between settings is relatively modest, with Ultra being 38.5% slower than Low. This indicates that the GPU is the primary bottleneck, as reducing graphical load produces direct FPS gains. The RTX 5090’s massive compute resources, including 21760 shading units and 104.8 TFLOPS of FP32 performance, are being fully utilized at 4K.

Moving to 2560x1440, the scaling between Low and Ultra is 40.7%, which is slightly larger than at 4K. This suggests the CPU is beginning to exert some influence, though the GPU still dominates the performance equation. The Ryzen 5 8400F’s 6 cores and 12 threads, with a boost clock of 4.70 GHz, are sufficient to keep the RTX 5090 fed at this resolution, as evidenced by the 176.9 FPS average on Ultra.

At 1920x1080, the CPU’s role becomes more pronounced. The difference between Low and Ultra is 39.0%, which is actually smaller than at 1440p. This counterintuitive result indicates that the CPU is capping performance at the lower end of the settings spectrum. The 387.4 FPS average on Low suggests the Ryzen 5 8400F’s single-thread performance, which ranks in the 77th percentile among all CPUs, is the limiting factor. The RTX 5090, which ranks in the 92nd percentile among GPUs, is capable of far more than the CPU can deliver at 1080p.

The resolution scaling from 4K to 1440p yields a 81.4% performance increase on Ultra settings, while the jump from 1440p to 1080p provides a 57.5% increase. This diminishing return at 1080p is a classic sign of CPU bottlenecking, where the GPU has excess capacity that cannot be utilized due to the processor’s frame submission rate.

Similar Performance Alternatives

For the CPU, the nearest rivals to the Ryzen 5 8400F are clustered very closely in average benchmark score. The AMD Ryzen 5 7500F is the closest match, with an average score of 24964 compared to the 8400F’s 25005, representing a negligible 0.2% difference. The Intel Core i7-11850H and Intel Core i7-13620H are also nearly identical, with scores of 24935 and 24911 respectively, showing deltas of 0.3% and 0.4%. On the other side, the AMD EPYC 9474F scores 25103, which is 0.4% higher. These results indicate that any of these processors would deliver essentially the same frame rates in Doom, with the CPU bottleneck at 1080p remaining unchanged.

On the GPU side, the RTX 5090’s nearest rivals are somewhat unexpected given its high-end positioning. The NVIDIA Tesla P100 PCIe 16 GB has an average score of 79605, just 0.3% lower than the RTX 5090’s 79842. The Tesla P100 PCIe 12 GB scores 79396, a 0.6% difference, while the AMD Radeon RX 6850M XT trails by 1.1% with a score of 78940. The AMD Radeon Pro Vega 64X is slightly ahead at 80959, showing a -1.4% delta. These comparisons suggest that in pure benchmark terms, the RTX 5090’s performance is matched by these enterprise and mobile parts, though the RTX 5090’s 32 GB of GDDR7 memory and 1.79 TB/s bandwidth would likely provide advantages in other workloads.

In practical terms for Doom, any of these GPU alternatives would produce nearly identical frame rates, with the deltaPct values all falling within 1.4% of each other. The RTX 5090’s percentile ranking of 92 places it firmly in the top tier, and the measured FPS data confirms that the GPU is never the limiting factor at any resolution in this game.

The Verdict

The data is unequivocal: this PC can run Doom at maximum settings across all tested resolutions. At 3840x2160, the Ultra preset maintains an average of 97.5 FPS, which is 62.5% above the 60 FPS playable threshold. This means users can enable every visual feature at 4K without worrying about stutter or drops below playable levels. The High preset at 4K achieves 118.9 FPS, providing even more headroom for those who prefer higher frame rates over maximum fidelity.

At 2560x1440, the Ultra preset delivers 176.9 FPS, which is nearly triple the playable threshold. This level of performance is ideal for high-refresh-rate monitors, as the frame rate is comfortably above 144 Hz. The 1920x1080 Ultra preset reaches 278.6 FPS, which exceeds even the most demanding 240 Hz displays. The lowest recorded average across all configurations is 97.5 FPS at 4K Ultra, so there is no scenario where this system dips below 60 FPS.

The verdict by resolution confirms that all four settings presets are playable at every resolution, with Ultra being the best choice in each case. The RTX 5090’s dominance ensures that the GPU is never the bottleneck, while the Ryzen 5 8400F provides sufficient CPU performance for this game. The only caveat is that the CPU limits the system to around 387 FPS at 1080p Low, but this is far beyond any practical display refresh rate. Overall, this configuration is overkill for Doom, delivering a flawless experience at any settings combination.
