Doom

How This Combo Ranks

The Intel Core i5-14400F paired with the NVIDIA GeForce RTX 3080 Ti places at rank 429 out of 1681 tested combos in Doom. This puts the configuration in the top 25% of all tested systems, a strong result for a game that scales well across hardware tiers. The ranking reflects a balance where the GPU's raw throughput carries the heavier load, while the CPU's 10 cores and 16 threads provide sufficient headroom to avoid bottlenecking at most settings. The data shows this combo sits comfortably ahead of the median tested system, though it does not crack the top tier reserved for flagship GPUs paired with flagship processors. Given the game's 2016 release, the hardware is more than capable of exploiting its optimization, and the 429th rank among 1681 combos underscores that this is a high-performing but not extreme configuration. The delta between this combo and the top-ranked systems is primarily driven by GPU compute limits at higher resolutions, as the CPU's benchmark percentile of 88 versus the GPU's 83 suggests the processor has more relative headroom than the graphics card.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing, and the measured frame rates confirm its central role. The GPU's 12 GB of GDDR6X memory on a 384-bit bus delivers 912.4 GB/s of bandwidth, which is ample for Doom's texture-heavy environments at any resolution tested. The memory clock runs at 1188 MHz with 19 Gbps effective speed, while the base clock sits at 1365 MHz and boosts to 1665 MHz. These clocks, combined with 10240 shading units and 80 RT cores, produce a peak FP32 throughput of 34.10 TFLOPS. In Doom, which does not heavily utilize ray tracing, the raw rasterization power matters most, and the data shows the GPU scaling predictably across settings. At 4K Ultra, the card delivers 68.6 FPS average, which is playable but indicates the GPU is nearing its limit. The GPU's benchmark scores reinforce this: a Passmark G3D score of 26896 and a 3DMark Steel Nomad DX12 score of 5077 place it at the 83rd percentile among all GPUs. Its nearest rival, the RTX 3090, scores 41441 in average benchmarks, a mere 0.5% higher, meaning the 3080 Ti is virtually on par with the 3090 in overall compute despite having 12 GB instead of 24 GB of VRAM. For Doom specifically, the 12 GB capacity is not a constraint, as even at 4K Ultra the game does not exceed this allocation.

Resolution Scaling

The measured FPS data reveals a clear pattern of GPU-bound scaling as resolution increases. At 1080p High, the combo averages 228.3 FPS, which drops to 151.1 FPS at 1440p High, a 33.8% reduction, and further to 80.2 FPS at 4K High, a 64.9% reduction from 1080p. This scaling is characteristic of a GPU-limited scenario: the CPU has enough headroom to feed the GPU at lower resolutions, but the RTX 3080 Ti's pixel throughput becomes the bottleneck as pixel count quadruples from 1080p to 4K. The Low setting shows the same trend more dramatically: 315.1 FPS at 1080p drops to 202.9 FPS at 1440p and 111.4 FPS at 4K. The percentage drops are consistent across settings, which indicates the limiting factor is the GPU's fill rate and memory bandwidth rather than any specific setting. At 1080p Low, the frame rate of 315.1 FPS approaches the CPU's ability to feed frames, suggesting that at very low settings the i5-14400F's 10 cores and 4.7 GHz boost clock begin to matter, but even then the GPU still holds the primary constraint. The data shows that moving from 1080p to 1440p costs roughly 34% performance across settings, while moving from 1440p to 4K costs an additional 47% on average, confirming the GPU's diminishing returns at higher pixel counts.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings presets, providing a complete picture of performance scaling. At 1920x1080, the combo delivers 315.1 FPS on Low, 274.5 FPS on Medium, 228.3 FPS on High, and 186.5 FPS on Ultra. These numbers indicate that even at the most demanding 1080p preset, the system maintains a frame rate well above typical high-refresh monitor capabilities. Moving to 2560x1440, the average FPS drops to 202.9 on Low, 178.2 on Medium, 151.1 on High, and 122.6 on Ultra. The 1440p results show that the combo remains highly playable across all settings, with even the Ultra preset staying above 120 FPS. At 3840x2160, the performance becomes more modest: 111.4 FPS on Low, 96.0 FPS on Medium, 80.2 FPS on High, and 68.6 FPS on Ultra. The 4K Ultra figure is the only measured result below 70 FPS, but it still meets the threshold for smooth gameplay on most displays. The scaling from Low to Ultra at each resolution shows a consistent pattern: Ultra is roughly 40-45% slower than Low at every resolution, which indicates the settings presets have a uniform impact on GPU load. The gap between Medium and High is smaller than between High and Ultra, suggesting that the Ultra preset includes effects that disproportionately tax the GPU.

CPU Role

The Intel Core i5-14400F serves as the supporting component in this combo, and its 10 cores and 16 threads are more than adequate for Doom's engine. The processor runs with a base clock of 2.50 GHz and boosts to 4.70 GHz, and its 20 MB of shared L3 cache provides fast access to frequently used data. The CPU's benchmark results show a balanced profile: a Cinebench R23 multicore score of 21914 and a single-core score of 3093, which places it at the 88th percentile among all CPUs. In Doom, which is primarily GPU-bound at higher resolutions, the CPU's role diminishes as pixel count increases. The data supports this: at 1080p Low, where the GPU has less work per frame, the average FPS of 315.1 likely approaches the CPU's frame delivery limit, but the system still achieves a high frame rate. At 4K Ultra, the CPU is almost certainly idle-waiting for the GPU, as the 68.6 FPS is far below what the processor could theoretically feed. The i5-14400F's nearest rival, the Intel Core i7-12800H, scores 32513 in average benchmarks, a 0% delta, meaning these CPUs are effectively interchangeable for gaming. The CPU's Passmark multithread score of 25783 and single-thread score of 3723 further confirm that it has ample single-core performance for Doom's engine, which does not heavily utilize more than a few threads. The 65 W TDP and Raptor Lake architecture ensure efficient operation without thermal throttling, which is beneficial for sustained gaming sessions.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1080p displays, the Ultra preset at 186.5 FPS is the clear recommendation, as it provides the highest visual quality while still delivering a frame rate that exceeds most 144Hz monitors' capabilities. The High preset at 228.3 FPS offers a marginal FPS increase but sacrifices visual fidelity for a frame rate that most users cannot perceive. At 1440p, the Ultra preset at 122.6 FPS is also recommended for high-refresh 144Hz monitors, as the frame rate is close enough to the refresh ceiling that most users would not notice the difference between Ultra and High (151.1 FPS). For 4K displays, the data presents a trade-off: the High preset at 80.2 FPS is the best balance for smooth gameplay on 60Hz displays, while the Medium preset at 96.0 FPS provides additional headroom for 120Hz panels. The Low preset at 111.4 FPS is only advisable for competitive play where maximum frame rate is prioritized over visuals, but the visual downgrade from Low to Medium is substantial. The Ultra preset at 4K (68.6 FPS) is playable on 60Hz displays but leaves no margin for frame time spikes, so the High preset is the safer choice for consistent performance. Overall, the data suggests that defaulting to High settings at any resolution provides a reliable experience, with Ultra reserved for users with displays that match the frame rate, and Medium used to ensure higher minimum frame rates on variable refresh rate monitors.
