Doom

Resolution Scaling

The data shows a clear progression of frame rates as resolution increases, with the Intel Core i5-14400F and NVIDIA GeForce RTX 3080 combo delivering playable performance across the board. At 1080p High settings, the combo averages 223.6 FPS, which drops to 145.2 FPS at 1440p and further to 76.4 FPS at 4K. This represents a 35% reduction from 1080p to 1440p and a 66% reduction from 1080p to 4K, indicating that the GPU becomes progressively more stressed as pixel count rises.

The scaling behavior reveals that at 1080p, the system is likely not fully GPU-bound, as the jump from Low to Ultra settings only reduces performance by about 40% (from 299.3 FPS to 180.4 FPS). However, at 4K, the same settings range shows a more dramatic 41% drop (from 104.3 FPS on Low to 62.4 FPS on Ultra), suggesting the RTX 3080's rendering pipeline is the primary limiting factor at higher resolutions. The 4K Ultra result of 62.4 FPS indicates that this resolution/settings combination is approaching the practical ceiling for smooth gameplay, while 4K High at 76.4 FPS offers a more comfortable margin.

Interestingly, the scaling from 1440p to 4K is steeper than from 1080p to 1440p. At High settings, 1440p delivers 145.2 FPS versus 4K's 76.4 FPS, a 47% reduction, while the 1080p to 1440p drop is only 35%. This non-linear scaling points to the GPU's memory bandwidth and compute resources being saturated as resolution increases, with the RTX 3080's 760.3 GB/s bandwidth and 29.77 TFLOPS of FP32 performance being pushed harder at 4K.

GPU Role

The NVIDIA GeForce RTX 3080 is the dominant component in this pairing for Doom, particularly at higher resolutions. Its 10 GB of GDDR6X memory on a 320-bit bus provides 760.3 GB/s of bandwidth, which is sufficient for the game's texture-heavy environments even at 4K Ultra. The GPU's 8704 shading units, 272 texture mapping units, and 96 ROPs work together to deliver the measured frame rates, with the boost clock of 1710 MHz providing the computational throughput needed for the game's fast-paced rendering.

The GPU's percentile ranking of 80 versus all GPUs places it in the upper quintile, and its nearest rivals show tight competition. The AMD Radeon RX 7900 GRE is only 0.9% ahead in average benchmark score, while the NVIDIA GeForce RTX 5070 Ti Mobile is 1% behind. This competitive positioning means the RTX 3080 remains a strong performer for this title, though the data suggests it is the bottleneck at 4K Ultra where the 62.4 FPS result is the lowest measured.

The GPU's 8 nm process node and 28,300 million transistors on a 628 mm² die contribute to its 320 W TDP, which requires a 700 W suggested power supply. The dual-slot design and 1x 12-pin power connector are notable physical characteristics, but the benchmark results are what matter most: the RTX 3080 delivers 104.3 FPS at 4K Low, showing that even at the highest resolution, the GPU can maintain high frame rates when settings are reduced.

How This Combo Ranks

This specific combination of Intel Core i5-14400F and NVIDIA GeForce RTX 3080 ranks 530 out of 1681 tested combos for Doom, placing it in the 68th percentile of all tested configurations. This ranking reflects a strong but not elite position, indicating that while the combo is capable of high frame rates, there are many faster configurations in the database.

The CPU component of this pairing performs admirably in isolation, with the i5-14400F achieving an 88th percentile ranking against all CPUs. Its 10 cores and 16 threads with a boost clock of 4.70 GHz provide ample processing power for the game's physics and AI calculations. The CPU's nearest rivals show minimal performance differences: the Intel Core i7-12800H matches it at 0% delta, the AMD Ryzen 5 PRO 7645 is 0.2% ahead, and both the AMD Ryzen 7 250 and Intel Core i7-13705H are 0.2% behind. This clustering suggests the i5-14400F is well-positioned within its performance class.

The GPU's 80th percentile ranking against all GPUs is slightly lower than the CPU's 88th percentile, which explains why the combo rank (68th percentile) falls below the CPU's individual standing. The RTX 3080's nearest rivals include the AMD Radeon Pro Duo at 0.2% ahead and the AMD Radeon 880M at 0.4% behind, showing that the GPU sits in a competitive mid-to-high tier. The combo's overall rank of 530 out of 1681 suggests that many higher-end GPUs paired with similar CPUs can outperform this setup, but it remains a solid mid-to-high tier configuration.

Settings Recommendations

For the best balance of visual quality and performance, the data clearly points to High settings as the optimal choice across all resolutions. At 1080p, High delivers 223.6 FPS, which is more than sufficient for any display, while offering significant visual improvements over Medium's 261 FPS and Low's 299.3 FPS. At 1440p, High maintains 145.2 FPS, making it the only setting that stays above the 144 Hz refresh rate threshold while still providing good visual fidelity.

Ultra settings are only recommended at 1080p, where 180.4 FPS remains highly playable. At 1440p, Ultra drops to 115.6 FPS, which is playable but sacrifices the high refresh rate experience. At 4K, Ultra's 62.4 FPS is the only result below 60 FPS, making it the least desirable option. For 4K users, High at 76.4 FPS is the recommended setting, as it provides a smooth experience while Medium at 92 FPS offers a slight performance boost with minimal visual compromise.

The data suggests that Medium settings provide diminishing returns at higher resolutions. At 4K, Medium's 92 FPS is only 20% faster than High's 76.4 FPS, and the visual difference between these settings is typically less noticeable than the frame rate improvement. Conversely, Low settings provide the highest frame rates but may not justify the visual sacrifices, especially at 1080p where even High settings are well above 200 FPS.

CPU Role

The Intel Core i5-14400F plays a supporting but important role in this Doom configuration. With 10 cores and 16 threads, the CPU provides sufficient parallel processing capability for the game's engine, which benefits from multiple threads for rendering tasks, physics calculations, and AI updates. The base clock of 2.50 GHz and boost clock of 4.70 GHz allow the CPU to scale performance dynamically, and the 20 MB of shared L3 cache helps reduce memory latency during intensive gameplay sequences.

The CPU's benchmark results show strong single-threaded and multi-threaded performance. Its Cinebench R23 multi-core score of 21914 and single-core score of 3093 place it in the 88th percentile of all CPUs, indicating that it is well above average for gaming workloads. The Geekbench scores of 11209 multi-core and 2333 single-core further confirm this positioning. The PassMark multi-thread score of 25783 and single-thread score of 3723 demonstrate that the CPU can handle both lightly-threaded and heavily-threaded workloads effectively.

However, the benchmark data reveals that the CPU is not the limiting factor in this combo for Doom. The significant frame rate differences between settings at the same resolution (e.g., 299.3 FPS at 1080p Low versus 180.4 FPS at 1080p Ultra) indicate that the GPU is the primary bottleneck when settings are increased. The CPU's 10-core, 16-thread configuration with a 65 W TDP is more than adequate for this game, and its 88th percentile ranking confirms it is a capable gaming processor that will not hold back the RTX 3080 in most scenarios.

Measured FPS Breakdown

The complete measured FPS data for this combo in Doom is as follows:

1080p:

• Low: 299.3 FPS
• Medium: 261.0 FPS
• High: 223.6 FPS
• Ultra: 180.4 FPS

1440p:

• Low: 195.5 FPS
• Medium: 169.3 FPS
• High: 145.2 FPS
• Ultra: 115.6 FPS

4K (3840x2160):

• Low: 104.3 FPS
• Medium: 92.0 FPS
• High: 76.4 FPS
• Ultra: 62.4 FPS

The data shows a consistent pattern: each resolution step reduces frame rates by roughly 35-47% depending on settings, and each settings step at a given resolution reduces performance by about 18-25%. The largest absolute drop occurs from 1080p Low to 4K Ultra (299.3 to 62.4 FPS, a 79% reduction), while the smallest absolute drop is from 1080p Ultra to 4K Ultra (180.4 to 62.4 FPS, a 65% reduction). This pattern confirms that both resolution and settings independently affect performance, with the GPU being the dominant factor at higher resolutions and settings.
