Doom

The Intel Core i5-12400F and NVIDIA GeForce RTX 3080 combination delivers a thoroughly overpowered experience for Doom, a 2016 FPS built on id Tech 6. Benchmark data shows this pairing clears the 60 FPS playable threshold at every settings preset across all three tested resolutions, with the most demanding Ultra preset remaining playable even at 4K. The data indicates this is a system where the GPU is the primary performance driver, and the CPU provides ample headroom to avoid becoming a bottleneck.

Best Settings per Resolution

At 3840x2160, the Ultra preset is the most demanding option that stays above 60 FPS, averaging 61.3 FPS. This is the ceiling for this resolution; pushing beyond Ultra is not possible, and the margin above the 60 FPS threshold is slim (1.3 FPS). For a more comfortable cushion, High settings average 81.1 FPS, while Medium averages 91 FPS and Low averages 106.6 FPS. Every preset is playable at 4K, but Ultra is the recommended choice for maximum visual fidelity if you accept the narrow frame time margin.

At 2560x1440, the Ultra preset averages 116.6 FPS, which is nearly double the 60 FPS threshold. This is the clear best setting, as it provides both high visual quality and a large performance buffer. High settings average 140.5 FPS, Medium averages 169.7 FPS, and Low averages 194.6 FPS, all far exceeding playability requirements. The data shows no reason to drop below Ultra at this resolution.

At 1920x1080, the Ultra preset averages 180.6 FPS, a figure that makes any lower preset unnecessary for playability. High settings average 223.4 FPS, Medium averages 259.7 FPS, and Low averages 299.4 FPS. The 1080p Ultra result is so far above the threshold that the only limiting factor would be a high-refresh-rate display's maximum capability, not the hardware. For competitive play, the Low preset at 299.4 FPS offers the highest possible frame rate, but for general use, Ultra is the sensible pick.

CPU and GPU Roles

The performance scaling across resolutions clearly indicates that the GPU is the dominant component for Doom. From 1920x1080 to 3840x2160 at Ultra settings, the average FPS drops from 180.6 to 61.3, a reduction of roughly 66%. This steep decline with increasing pixel count is classic GPU-bound behavior, where the rendering load scales directly with resolution. The RTX 3080's 10 GB of GDDR6X memory and 760.3 GB/s bandwidth are fully utilized at higher resolutions, while the CPU's workload remains relatively constant.

The CPU's role becomes more apparent at lower resolutions and lower presets. At 1920x1080 Low, the system averages 299.4 FPS, which is likely near the engine's practical frame rate ceiling. The Core i5-12400F, with its 6 cores and 12 threads and a boost clock of 4.40 GHz, provides enough single-thread performance to feed the GPU at these extreme frame rates. However, the data shows diminishing returns: going from Medium to Low at 1080p only increases FPS from 259.7 to 299.4, a 15% gain, whereas at 4K the same preset change yields a 17% gain (from 91 to 106.6). This pattern suggests that at 1080p, the CPU begins to impose a soft limit on maximum FPS, but it is not a bottleneck that affects playability.

Preset scaling reinforces this interpretation. At 4K, dropping from Ultra to Low increases FPS from 61.3 to 106.6, a 74% improvement. At 1440p, the same drop increases FPS from 116.6 to 194.6, a 67% improvement. At 1080p, the increase is from 180.6 to 299.4, a 66% improvement. The consistent percentage gains across resolutions indicate that the GPU is scaling predictably with settings, and the CPU is not introducing a variable constraint. The i5-12400F is a capable partner, but the RTX 3080 is clearly the component that determines the playable experience.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across all combinations of resolution and settings. No minimum or maximum frame rate data was recorded, so the analysis relies on average FPS figures.

At 3840x2160, the average frame rates are: Low 106.6 FPS, Medium 91 FPS, High 81.1 FPS, and Ultra 61.3 FPS. The progression shows a consistent 10-15 FPS penalty for each step up in quality, with the Ultra preset being the only one that approaches the 60 FPS playable threshold.

At 2560x1440, the average frame rates are: Low 194.6 FPS, Medium 169.7 FPS, High 140.5 FPS, and Ultra 116.6 FPS. The gap between High and Ultra is 23.9 FPS, which is the largest single-step drop at this resolution. All presets provide a substantial margin above 60 FPS.

At 1920x1080, the average frame rates are: Low 299.4 FPS, Medium 259.7 FPS, High 223.4 FPS, and Ultra 180.6 FPS. The differences between presets are large in absolute terms but proportionally similar to other resolutions. The Low preset result of 299.4 FPS is the highest measured frame rate for this combination, indicating a hard ceiling likely set by the game engine or CPU.

Cross-resolution scaling at Ultra settings shows: 1080p at 180.6 FPS, 1440p at 116.6 FPS, and 4K at 61.3 FPS. This means 1440p delivers 64.6% of the 1080p frame rate, and 4K delivers 52.6% of the 1440p frame rate. The scaling is not linear, which is typical for a GPU-bound workload where memory bandwidth and pixel fill rate become limiting factors at higher resolutions.

Similar Performance Alternatives

For the CPU, the nearest rivals based on average benchmark score are all within a fraction of a percent of the Core i5-12400F's 19039 average. The AMD Ryzen 5 7535HS scores 19047, a delta of 0%, meaning it would behave nearly identically in CPU-bound scenarios. The Intel Core 3 201E scores 19056 with a delta of -0.1%, the Intel Core i5-1335U scores 18982 with a delta of 0.3%, and the AMD EPYC 7773X scores 18979 with a delta of 0.3%. In practice, any of these processors would deliver the same level of performance in Doom, which means they will not bottleneck the RTX 3080 at any resolution. The differences are negligible for gaming workloads.

For the GPU, the nearest rivals are also extremely close in average score. The NVIDIA P106-100 scores 23249 with a delta of -0.3% against the RTX 3080's 23172. The AMD Radeon Pro Vega 16 scores 23250 with a delta of -0.3%, the AMD Radeon RX 6600M scores 23273 with a delta of -0.4%, and the AMD Radeon R9 M290X scores 23276 with a delta of -0.4%. These deltas are within the margin of error for benchmark variation, meaning any of these GPUs would produce nearly identical frame rates in Doom. However, it is important to note that several of these rivals are mobile or workstation parts, so their thermal and power characteristics differ from the desktop RTX 3080, even if their raw performance scores are comparable.

The Verdict

The verdict by resolution is unambiguous: this PC can run Doom at every tested setting preset and resolution. At 3840x2160, the playable settings include High, Low, Medium, and Ultra, with Ultra being the best setting at an average of 61.3 FPS. At 2560x1440, all four presets are playable, with Ultra averaging 116.6 FPS. At 1920x1080, all four presets are playable, with Ultra averaging 180.6 FPS.

The data confirms that the 60 FPS threshold is cleared in every scenario, and the only question is how much visual quality you want to sacrifice for higher frame rates. At 4K, the Ultra preset is just barely playable, so you might prefer High for a more stable margin. At 1440p and 1080p, Ultra is not only playable but leaves enormous headroom, making it the obvious choice. This system is overqualified for Doom, which is not a demanding title by modern standards, and it will run the game at maximum settings with no compromises on any common display configuration.

How This Combo Ranks

In the benchmark database, this Intel Core i5-12400F + NVIDIA GeForce RTX 3080 combination ranks 1083 out of 3712 tested combos for Doom. This places it in the top 29.2% of all configurations tested for this game. Given that the measured FPS data shows this combo easily exceeding the playable threshold at all resolutions and presets, the rank reflects that there are many higher-performing combinations, likely featuring newer or more expensive hardware. However, the rank also indicates that this combo outperforms the majority of tested systems. For a mid-range CPU paired with a high-end GPU from the previous generation, this is a strong showing. The data suggests that while this is not a top-tier combo, it is more than sufficient for Doom, and the high frame rates at 1080p and 1440p put it in a comfortable position for competitive play or high-refresh-rate displays.
