Doom

The Intel Core i5-14400F paired with the NVIDIA GeForce RTX 5090 delivers exceptional performance in Doom, with every tested resolution and settings combination far exceeding the 60 FPS playable threshold. The data indicates a system with massive headroom, where even the most demanding preset at 4K produces an average of 99.5 FPS. This combination ranks 84th out of 3,712 tested combos for this title, placing it in the top 2.3% of all configurations.

Measured FPS Breakdown

At 1920x1080, the combination produces staggering frame rates that are largely irrelevant for typical displays but demonstrate the raw ceiling of the hardware. The lowest measured average at this resolution is 275.6 FPS on the Ultra preset, which is still more than four times the 60 FPS threshold. The Low preset reaches an average of 388.7 FPS, while Medium sits at 368.8 FPS and High at 341.8 FPS. The scaling from Low to Ultra shows a performance drop of 113.1 FPS (from 388.7 to 275.6), representing a 29% reduction in throughput as graphical load increases.

Moving to 2560x1440, the same pattern holds but with slightly compressed margins. The Low preset averages 297.9 FPS, which drops to 261.6 FPS at Medium, 216.6 FPS at High, and 177.8 FPS at Ultra. The delta between Low and Ultra here is 120.1 FPS, a 40% reduction. This larger percentage drop compared to 1080p suggests that the GPU is beginning to take on more meaningful work at this resolution, though the absolute numbers remain far beyond what any current display can refresh.

At 3840x2160, the results show the most pronounced scaling. The Low preset averages 158.9 FPS, Medium averages 141.8 FPS, High averages 120.6 FPS, and Ultra averages 99.5 FPS. The difference between Low and Ultra is 59.4 FPS, a 37% reduction. Notably, the gap between Medium and High (21.2 FPS) is larger than the gap between High and Ultra (21.1 FPS), suggesting a relatively linear cost for each settings tier at 4K.

Best Settings per Resolution

At 1920x1080, the best settings that remain at or above 60 FPS are the Ultra preset, which achieves an average of 275.6 FPS. Every other preset also clears the threshold, but Ultra represents the maximum visual quality without any compromise. The margin above the 60 FPS floor is 215.6 FPS, meaning there is no practical scenario where this resolution would strain the hardware.

For 2560x1440, the Ultra preset again provides the best experience, with an average of 177.8 FPS. The margin above 60 FPS is 117.8 FPS, still leaving substantial headroom. All four presets at this resolution clear the threshold, so the choice is purely about visual preference rather than playability.

At 3840x2160, the Ultra preset maintains an average of 99.5 FPS, which is 39.5 FPS above the 60 FPS threshold. This is the only resolution where the margin narrows to less than double the playable threshold, but it still comfortably clears the bar. High preset at 120.6 FPS would be an alternative for users seeking a larger buffer, but the data shows Ultra is fully viable at 4K.

CPU and GPU Roles

The benchmark data reveals how the balance between CPU and GPU shifts across resolutions. At 1920x1080, the frame rates are so high (388.7 FPS at Low) that the combination is likely constrained by the CPU's ability to feed the GPU. The i5-14400F, with its 10 cores and 16 threads, produces a Cinebench R23 multi-core score of 21,645 and a single-core score of 3,055, which positions it in the 83rd percentile of all CPUs. At 1080p, the 29% drop from Low to Ultra (388.7 to 275.6 FPS) indicates that the GPU is still the dominant factor, but the absolute numbers suggest the CPU is working near its limit.

At 2560x1440, the GPU begins to take on more of the load. The 40% reduction from Low to Ultra (297.9 to 177.8 FPS) is larger than at 1080p, indicating that the increased pixel count is making the GPU the primary bottleneck. The CPU's role diminishes as resolution rises, which is typical for a GPU-heavy title like Doom. The i5-14400F's passmark multi-thread score of 25,470 and single-thread score of 3,701 are sufficient to avoid becoming a constraint at this resolution.

At 3840x2160, the GPU is clearly the dominant component. The 37% reduction from Low to Ultra (158.9 to 99.5 FPS) shows that even the RTX 5090, with its 104.8 TFLOPS FP32 throughput and 32 GB of GDDR7 memory on a 512-bit bus, is being pushed hard by the 4K resolution. The CPU's influence is minimal here, as the frame rates are driven by the GPU's pixel throughput and memory bandwidth. The RTX 5090's 1.79 TB/s bandwidth is the key enabler for maintaining playable frame rates at this resolution.

Similar Performance Alternatives

For the CPU, the nearest rivals to the i5-14400F are clustered within a narrow band. The AMD Ryzen 7 PRO 8840U scores 32,233 in the average benchmark, which is 0.1% lower than the i5-14400F's 32,279. The Intel Core i9-11900 scores 32,226, a 0.2% delta, while the AMD Ryzen 7 6800HS scores 32,354, which is 0.2% higher. The Intel Core i7-12800H scores 32,121, a 0.5% deficit. These four alternatives would behave nearly identically in Doom, as their performance differences are well within run-to-run variance.

For the GPU, the Ryzen 7 PRO 8840U and Core i9-11900 are not the relevant comparison; instead, the RTX 5090's nearest rivals show a wider spread. The NVIDIA Tesla P100 PCIe 16 GB scores 79,605, which is 0.3% lower than the RTX 5090's 79,842 average. The Tesla P100 PCIe 12 GB scores 79,396, a 0.6% deficit, while the AMD Radeon RX 6850M XT scores 78,940, a 1.1% gap. The AMD Radeon Pro Vega 64X scores 80,959, which is 1.4% higher. These GPUs would produce nearly identical frame rates in Doom, though the Tesla P100 variants lack the RTX 5090's modern feature set.

How This Combo Ranks

This specific combination of the Intel Core i5-14400F and NVIDIA GeForce RTX 5090 ranks 84th out of 3,712 tested combos for Doom. This places it in the 97.7th percentile of all configurations, meaning only 83 other combinations out of 3,712 produce higher frame rates. Given that the RTX 5090 is among the most powerful GPUs available, the ranking is primarily determined by the CPU's position in the 83rd percentile of all CPUs. The i5-14400F's 10 cores and 16 threads are sufficient for this title, but faster CPUs would likely push the ranking higher at lower resolutions where the CPU bottleneck is more pronounced. The 4K results, where the GPU dominates, show the RTX 5090's full potential, and the combination ranks highly even with a mid-range CPU.

The Verdict

This PC can absolutely run Doom at every resolution and preset combination tested. At 1920x1080, the Ultra preset delivers 275.6 FPS, clearing the 60 FPS threshold by 215.6 FPS. At 2560x1440, Ultra achieves 177.8 FPS, a margin of 117.8 FPS. Even at 3840x2160, the most demanding scenario, Ultra averages 99.5 FPS, which is 39.5 FPS above the playable threshold. The verdictByResolution data confirms that all four settings presets (Low, Medium, High, and Ultra) are playable at every resolution, with Ultra being the best settings option at each. This combination offers no practical limitations for Doom, making it suitable for any display configuration currently available, including high-refresh 1440p monitors and 4K displays with VRR. The only scenario where the hardware would show its limits is at 4K Ultra with a 120 Hz or higher refresh rate, where the 99.5 FPS average would not fully saturate the display.
