Doom

Measured FPS Breakdown

The recorded data for Doom with the Intel Core i5-12400 and NVIDIA GeForce RTX 4090 shows exceptionally high frame rates across every resolution and preset combination. At 1920x1080, the average frame rates span from 267 FPS at Ultra settings up to 363 FPS at Low settings. The Medium preset at this resolution averages 345 FPS with a minimum of 294 FPS and a maximum of 397 FPS, while the High preset averages 326 FPS. These figures indicate the combination delivers far more performance than a 60 FPS display can use, making even the most demanding preset a comfortable option for high refresh rate monitors.

Moving to 2560x1440, the average frame rates remain very high. The Low preset averages 287 FPS, Medium averages 250 FPS with a minimum of 213 FPS and a maximum of 288 FPS, High averages 211 FPS, and Ultra averages 173 FPS. The gap between Low and Ultra at this resolution is 114 FPS, which shows that the Ultra preset imposes a meaningful load increase, yet the absolute numbers stay well above any playability concern.

At 3840x2160, the averages drop but remain strong. Low settings produce 156 FPS, Medium averages 136 FPS with a minimum of 115 FPS and a maximum of 156 FPS, High averages 115 FPS, and Ultra averages 94 FPS. The scaling from 1080p to 4K is substantial: at Ultra settings, the average falls from 267 FPS at 1920x1080 to 94 FPS at 3840x2160, a reduction of 173 FPS. Even so, the lowest recorded average in the entire dataset, 94 FPS at 4K Ultra, clears the 60 FPS playability threshold by a wide margin.

The data shows a consistent pattern across presets. The Low preset consistently yields the highest average FPS at every resolution, followed by Medium, then High, then Ultra. The Medium preset is the only configuration where min and max values were recorded, providing a useful window into frame pacing: at 3840x2160 Medium, the range is 115 to 156 FPS, at 2560x1440 Medium it is 213 to 288 FPS, and at 1920x1080 Medium it is 294 to 397 FPS. These ranges confirm that even the minimum frame rates never approach the playability threshold.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-12400, based on average benchmark scores, include the AMD EPYC 7643 with an average score of 18697 and a delta of -0.1 percent, the Intel Core i7-1355U with 18730 and a delta of -0.3 percent, the AMD Ryzen AI 5 330 with 18811 and a delta of -0.7 percent, and the Intel Core i3-14100F with 18519 and a delta of 0.9 percent. The i5-12400 itself has an average benchmark score of 18683, placing it within a very tight band of these alternatives. The differences are small, so in Doom, where the CPU is not the limiting factor at most settings, any of these processors would likely produce similar frame rates when paired with the same GPU.

The nearest rivals for the NVIDIA GeForce RTX 4090 include the Intel Arc Pro A60 with an average score of 60326 and a delta of 0 percent, the AMD Radeon Pro Vega 48 with 60140 and a delta of 0.3 percent, the AMD Radeon Pro W6600M with 61896 and a delta of -2.5 percent, and the AMD Radeon PRO V710 with 58657 and a delta of 2.9 percent. The RTX 4090 has an average benchmark score of 60347. These GPUs are close in aggregate benchmark terms, though the RTX 4090 benefits from a much larger memory pool of 24 GB of GDDR6X and a 384 bit memory bus with 1.01 TB/s bandwidth, details that matter in other workloads but are less relevant to Doom at these frame rates.

For a game like Doom, the benchmark results indicate that a user with a differently configured system featuring one of these nearby CPUs or GPUs would see broadly comparable performance. The deltas are all within roughly 3 percent, so none of these alternatives would meaningfully change the playability verdict at any resolution.

CPU and GPU Roles

The recorded data shows that the GPU dominates performance scaling in Doom across resolutions. The CPU, an Intel Core i5-12400 with 6 cores, 12 threads, and a boost clock of 4.40 GHz, has a percentile of 72 against all CPUs and an average benchmark score of 18683. The GPU, an RTX 4090 with a percentile of 88 against all GPUs and an average benchmark score of 60347, is the component that scales with resolution changes. As resolution increases from 1920x1080 to 3840x2160, the average FPS at Ultra drops from 267 to 94, a decline that tracks the increasing pixel workload placed on the GPU. The CPU's role is more visible at lower resolutions where frame rates are extremely high; at 1920x1080 Low, the average of 363 FPS approaches the practical ceiling where CPU-bound behavior can emerge, but the i5-12400 still delivers enough throughput to keep the average above 360 FPS.

The scaling between presets also indicates GPU dominance. At 3840x2160, the difference between Low and Ultra is 62 FPS, while at 1920x1080 it is 96 FPS. The larger absolute gap at 1080p suggests that the CPU has more headroom to feed the GPU at lower resolutions, allowing preset changes to express themselves fully. At 4K, the GPU becomes more saturated, compressing the spread between presets. This pattern is typical for a game running on a high-end GPU paired with a mid-range CPU: the GPU is the limiting factor at higher resolutions, while the CPU matters more at lower resolutions and very high frame rates.

The i5-12400's single-thread performance, reflected in its 3dmark_single_thread score of 910 and passmark_single_thread score of 3456, is sufficient to avoid bottlenecking the RTX 4090 in this title. The game's release in 2016 means its engine does not rely on extremely high core counts, so the 6-core, 12-thread configuration is adequate. The data shows no preset or resolution where the combination falls below 94 FPS, indicating that neither component becomes a severe constraint.

How This Combo Ranks

The combination of the Intel Core i5-12400 and NVIDIA GeForce RTX 4090 ranks 158 out of 3712 tested combos in this game, placing it in the top 4.3 percent of all configurations recorded in the database. This rank reflects the strength of the RTX 4090, which anchors the combo with a passmark_g3d score of 38194 and a passmark_gpu_compute score of 26613. The CPU, while not the highest performer in the database, contributes enough to keep the combo near the top of the rankings. The i5-12400's avgBenchmarkScore of 18683 and the RTX 4090's avgBenchmarkScore of 60347 combine to produce a system that outperforms the overwhelming majority of tested hardware.

The rank of 158 out of 3712 is consistent with the measured FPS data. A combo that averages 94 FPS at 4K Ultra and 267 FPS at 1080p Ultra is clearly positioned among the fastest systems in the database. The percentile values support this: the CPU sits at the 72nd percentile, while the GPU sits at the 88th percentile, and the GPU's higher percentile drives the combo's overall standing. Systems ranked above this combo likely include CPUs with higher multi-threaded scores, such as those with more cores, or GPUs with even higher raw compute, but the measured game performance shows that the i5-12400 and RTX 4090 pairing leaves little on the table in Doom specifically.

The Verdict

The verdict by resolution confirms that this PC can run Doom at every tested setting. At 1920x1080, all four presets are playable, with Ultra averaging 267 FPS, High averaging 326 FPS, Medium averaging 345 FPS, and Low averaging 363 FPS. The best settings at this resolution are Ultra, delivering 267 FPS. At 2560x1440, all four presets are also playable, with Ultra averaging 173 FPS, High averaging 211 FPS, Medium averaging 250 FPS, and Low averaging 287 FPS. The best settings are Ultra at 173 FPS. At 3840x2160, all four presets clear the 60 FPS threshold as well, with Ultra averaging 94 FPS, High averaging 115 FPS, Medium averaging 136 FPS, and Low averaging 156 FPS. The best settings at 4K are Ultra at 94 FPS.

The playable threshold is 60 FPS, and every recorded average in the dataset exceeds it. The minimum recorded frame rates, available only for the Medium preset, are 115 FPS at 4K, 213 FPS at 1440p, and 294 FPS at 1080p, all far above the threshold. This combination does not merely run the game; it runs it with enough headroom for high refresh rate displays at 1080p and 1440p, and with solid 4K performance at maximum settings. The RTX 4090's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth are more than adequate for the game's demands, and the i5-12400's 18 MB of L3 cache and 12 threads handle the CPU workload without issue.
