FAQ

*Q: What is the best resolution and settings combination for this hardware in Doom?*

A: Based on the measured FPS data, 1920x1080 with Medium settings delivers an average of 272 FPS, which provides a substantial performance buffer. For a balance of visual quality and speed, 2560x1440 with High settings is excellent, averaging 149 FPS. At 4K, the High preset still yields a smooth 81 FPS average.

Q: How does this combo rank compared to all other tested combinations?

A: The Intel Core i5-12400 + RTX 3080 Ti ranks 963rd out of 3712 total tested combos, placing it in the 74th percentile. This indicates that it outperforms roughly three-quarters of all other CPU/GPU pairings tested in this game.

Q: Is the CPU or GPU the limiting factor for performance in this game?

A: At higher resolutions like 3840x2160, the GPU is the primary driver, as the frame rate drops significantly from 109 FPS on Low to 66 FPS on Ultra settings. However, the CPU is not a bottleneck, as even at 1080p Low, the combo achieves 312 FPS, showing strong single-thread performance.

Q: What is the difference between the Low and Ultra presets in terms of FPS?

A: The gap is significant. At 1920x1080, the average FPS drops from 312 on Low to 188 on Ultra, a difference of 124 FPS. At 2560x1440, the drop is from 202 FPS to 122 FPS, and at 4K, from 109 FPS to 66 FPS.

Q: Does the 12 GB of VRAM on the RTX 3080 Ti prove sufficient for the highest settings?

A: The data suggests it is more than adequate. The Ultra preset at 4K is the most demanding scenario tested, and it still runs at an average of 66 FPS, indicating that the 12 GB frame buffer is not causing performance to collapse or hit a hard limit.

Q: How does the CPU's multi-threaded performance compare to its nearest rivals?

A: The i5-12400 has an average benchmark score of 18683, which is virtually identical to its closest rival, the AMD EPYC 7643, which scores 18697, a negligible difference of -0.1%. It also edges out the Intel Core i3-14100F, which scores 18519, by 0.9%.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor from the Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. In Doom, which is an older title with a highly efficient engine, the CPU's single-thread performance is crucial for maintaining high frame rates, especially at lower resolutions where the GPU is not the bottleneck.

The benchmark results for this CPU show strong single-thread capability, with a 3dmark_single_thread score of 910 and a Passmark single-thread score of 3456. This translates directly to the game's ability to process game logic and draw calls quickly. This is evident in the measured FPS data: at 1920x1080 with Low settings, the combo reaches an average of 312 FPS. This high frame rate is a clear indicator that the CPU is able to feed the GPU with enough data to avoid holding it back, even at such high output levels.

The i5-12400's multi-threaded performance is also robust. With a Cinebench R23 multi-core score of 15989 and a Geekbench multi-core score of 8564, it can handle the game's background tasks and any additional system load without issue. Its overall average benchmark score of 18683 places it at the 72nd percentile of all CPUs, and its performance is nearly indistinguishable from its nearest rivals. For instance, it is only -0.1% behind the AMD EPYC 7643 and -0.3% behind the Intel Core i7-1355U, while being 0.9% ahead of the Intel Core i3-14100F. This indicates a well-balanced CPU that provides a solid foundation for the high-end GPU in this pairing, ensuring that the system's performance is not CPU-limited in most gameplay scenarios.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the undisputed powerhouse in this combination. With a GA102 chip on the Ampere architecture, it features 10240 shading units and 80 RT cores. Its 12 GB of GDDR6X memory on a 384-bit bus provides a massive 912.4 GB/s of bandwidth, which is essential for feeding the high-resolution textures and effects in Doom at high settings.

The GPU's raw compute power is substantial, with an FP32 performance of 34.10 TFLOPS. This translates into the high frame rates observed in the data. The GPU's percentile rank of 83rd among all GPUs, with an average benchmark score of 41187, confirms its high-end status. Its closest rivals include the NVIDIA GeForce RTX 5070 (2% higher) and the NVIDIA Tesla M40 24 GB (-1.2% lower), showing it remains a competitive performer even against newer generations.

In Doom, the GPU's role becomes increasingly dominant as resolution and settings increase. At 3840x2160, the average frame rate scales directly with the graphics preset: from 109 FPS on Low to 95 FPS on Medium, 81 FPS on High, and 66 FPS on Ultra. This clear delineation shows that the RTX 3080 Ti is the primary factor determining performance at 4K. The 12 GB VRAM appears more than sufficient for this game, as even the most demanding Ultra preset at 4K does not cause frame rates to plummet, indicating no memory-related stuttering or crashes. This GPU is built to handle the most demanding scenarios, and the data confirms it does so with authority.

How This Combo Ranks

The pairing of the Intel Core i5-12400 and the NVIDIA GeForce RTX 3080 Ti ranks 963rd out of 3712 tested combos in Doom. This is a strong performance, placing the system in the top 26% of all possible pairings tested. This rank is not surprising given the strengths of both components. The CPU is a solid mid-range performer, ranking in the 72nd percentile, and the GPU is a high-end part, ranking in the 83rd percentile.

The combined rank of 963 suggests that the system is well-balanced for this game. The CPU is not weak enough to bottleneck the GPU, and the GPU is powerful enough to leverage the CPU's capabilities fully. The data shows that the system is capable of delivering excellent performance at all tested resolutions, from the blistering 312 FPS at 1080p Low to the smooth 81 FPS at 4K High. This rank demonstrates that while there are many more powerful combinations available, this pairing is far above average and can provide a premium gaming experience. It outclasses the majority of systems, making it a high-performance option that will not struggle with Doom's fast-paced action.

Settings Recommendations

For most players, the ideal setting is the Medium preset. This setting offers an excellent balance between visual fidelity and raw performance. At 1920x1080, the Medium preset delivers an average of 272 FPS, which is more than enough for any high-refresh-rate monitor. At 2560x1440, it still produces a blistering 176 FPS, and even at 4K, it maintains a very playable 95 FPS with a minimum of 81 FPS. This makes it a universal choice that guarantees a high-performance experience across all resolutions.

If you have a 1440p 144Hz monitor, the High preset is the best choice. It maintains an average of 149 FPS at 2560x1440, which is still well above the refresh rate threshold for smooth gameplay. For 4K gaming, the High preset is also excellent, providing an 81 FPS average that is perfectly smooth for a fast-paced FPS. The Ultra preset is viable for those who demand the absolute best visuals, but it does come at a significant performance cost. At 1080p it drops to 188 FPS, at 1440p to 122 FPS, and at 4K to 66 FPS. While still playable, the substantial drop from High makes it less optimal for competitive play. The Low preset is not recommended for this hardware, as the high frame rates (312 FPS at 1080p) are unnecessary and the visual downgrade is severe.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at how this combo performs across all settings and resolutions.

1920x1080: This resolution shows the system's maximum potential. The Low preset produces an average of 312 FPS. The Medium preset sees a slight reduction to an average of 272 FPS, with a minimum of 231 and a maximum of 313. The High preset averages 230 FPS, and the Ultra preset averages 188 FPS. All settings are exceptionally playable at this resolution, with the performance being primarily limited by the CPU's single-thread speed.
