Doom

The Intel Core i5-14400F paired with the NVIDIA GeForce RTX 5080 is an exceptionally powerful combination for running Doom, placing 169th out of 3712 tested combos in this specific game. This top-tier percentile ranking (top 5%) reflects a system built to obliterate the game’s demands, delivering frame rates that far exceed the 60 FPS playable threshold across every resolution and preset tested. The data indicates a machine that turns Doom from a fast-paced shooter into an exercise in raw, uncompromising performance, with the only question being how high the refresh rate monitor can go.

How This Combo Ranks

Out of 3,712 tested hardware combinations for Doom, this CPU-GPU pairing secures the 169th position. That places it in the top 4.6% of all tested systems, a remarkable feat given the breadth of configurations possible. The rank is driven almost entirely by the GPU’s overwhelming compute power, as the RTX 5080 sits in the 87th percentile of all GPUs, while the i5-14400F is a solid but less dominant performer in the 83rd percentile of all CPUs. This suggests the combo is slightly GPU-limited at the highest settings, but the overall rank shows that the two components work together to crush the game’s requirements. For context, this system would outpace the vast majority of gaming rigs, making it a high-end contender for 4K ultra-smooth gameplay. The 3712-combo pool includes many older and weaker parts, so a 169th rank signals elite-level performance, not just adequacy.

CPU and GPU Roles

The division of labor between the i5-14400F and the RTX 5080 becomes clear when examining frame rates across resolutions. At 1080p, the CPU becomes the primary bottleneck, as the GPU is so powerful that it can render frames faster than the processor can feed it. The difference between Low and Ultra settings at 1080p is 136.2 FPS (390.9 vs 254.7), which is a 35% drop, indicating that the GPU is still doing significant work but the CPU’s 10 cores and 16 threads are stretched to maintain high frame pacing. Moving to 1440p, the GPU begins to assert dominance; the gap between Low (272.6 FPS) and Ultra (162.9 FPS) widens to 109.7 FPS, a 40% reduction, showing that the RTX 5080’s 56.28 TFLOPS of FP32 compute is now the limiting factor. At 4K, the GPU is fully saturated, and the scaling becomes more linear: Low (148.4 FPS) to Ultra (93.1 FPS) is a 37% drop, but the absolute numbers remain staggeringly high. The i5-14400F’s 20 MB of L3 cache and 4.70 GHz boost clock are sufficient to avoid severe CPU stalls, but the data shows that the RTX 5080 is the star, with the CPU merely enabling rather than limiting performance at higher resolutions.

Measured FPS Breakdown

The measured data paints a picture of consistent, massive headroom above the 60 FPS playable threshold. At 1920x1080, the combo starts at 314.1 FPS on High settings, climbs to 369.4 FPS on Medium, peaks at 390.9 FPS on Low, and drops to 254.7 FPS on Ultra. These numbers are so high that they exceed the refresh rate of most monitors, making the choice of settings a matter of visual fidelity versus raw frame rate. At 2560x1440, performance remains blistering: High delivers 202.3 FPS, Medium 241.3 FPS, Low 272.6 FPS, and Ultra 162.9 FPS. The 1440p Ultra figure is still 2.7x the playable threshold, meaning gamers can max out every graphical option without worrying about dips. At 3840x2160, the RTX 5080’s 16 GB of GDDR7 memory and 960.0 GB/s bandwidth come into play: High yields 113 FPS, Medium 127.4 FPS, Low 148.4 FPS, and Ultra 93.1 FPS. Even at 4K Ultra, the system maintains a 93.1 FPS average, which is 55% above the 60 FPS target. The lack of min/max FPS data in the pack means the analysis relies on averages, but the massive gaps between average FPS and the playable threshold suggest that even worst-case scenarios would remain fluid.

Similar Performance Alternatives

For the Intel Core i5-14400F, benchmark data shows it performs within a hair of several AMD and Intel rivals. The AMD Ryzen 7 PRO 8840U is essentially tied, with a delta of just 0.1% (32233 vs 32279 average score). The Intel Core i9-11900 is 0.2% behind, while the AMD Ryzen 7 6800HS is 0.2% ahead. The Intel Core i7-12800H is 0.5% behind. In practice, any of these CPUs would yield nearly identical frame rates in Doom, as the game is not heavily CPU-bound at higher resolutions. For the NVIDIA GeForce RTX 5080, the nearest GPU rivals are the AMD Radeon 8060S (0.6% lower average score), AMD Radeon RX 6750 GRE 12 GB (0.7% lower), and AMD Radeon Pro W5700X (2.3% lower). The AMD Radeon RX 9070 GRE is 2.2% faster. Swapping to any of these GPUs would produce frame rates within 1-2% of the RTX 5080, meaning a system with an i5-14400F and an RX 9070 GRE would deliver nearly identical Doom performance. The key takeaway is that the i5-14400F is not a unique enabler; many mid-range CPUs from the same era will match it, but the GPU choice dominates the final FPS numbers.

The Verdict

This system is unequivocally capable of running Doom at maximum performance. The verdict data confirms that all four settings (Low, Medium, High, Ultra) are playable at every tested resolution, including 3840x2160. At 4K, the best settings are Ultra, delivering a 93.1 FPS average, which clears the 60 FPS threshold by 55%. At 2560x1440, Ultra settings yield 162.9 FPS, a 2.7x margin over playability. At 1920x1080, Ultra settings produce 254.7 FPS, making this combo ideal for high-refresh-rate monitors. The RTX 5080’s 16 GB GDDR7 memory and 960.0 GB/s bandwidth ensure no texture or bandwidth bottlenecks, while the i5-14400F’s 10 cores and 4.70 GHz boost clock provide ample CPU headroom. The weakest point in the entire dataset is 4K Ultra at 93.1 FPS, yet that is still a stellar result for a demanding game. This PC does not just run Doom; it dominates it at every resolution and setting, making it a top-tier choice for gamers who refuse to compromise on frame rate or fidelity.
