Doom

The Intel Core i5-12400 paired with the NVIDIA GeForce RTX 5070 delivers overwhelming performance in Doom, with every tested resolution and preset combination clearing the 60 FPS playability threshold. The data shows a system that is never constrained by playability concerns, instead offering headroom that ranges from comfortable at 4K Ultra to extreme at 1080p Low. The measured frame rates indicate this combination is far more powerful than the game demands, with the only meaningful question being how much visual quality the user sacrifices for additional speed.

Measured FPS Breakdown

At 1920x1080, the combination produces frame rates that far exceed standard display refresh rates. On Low settings, the average FPS reaches 339.4, which is the highest figure recorded across all tests. Medium settings yield 297.7 FPS, while High settings produce 252.8 FPS. Even the most demanding Ultra preset maintains an average of 205.3 FPS at this resolution. The scaling between presets is substantial but consistent: moving from Ultra to High adds 47.5 FPS, High to Medium adds 44.9 FPS, and Medium to Low adds 41.7 FPS. This linear progression suggests the GPU has ample spare capacity, with the frame rate differences reflecting the increased shading and texture workloads of higher presets.

Stepping up to 2560x1440, the performance remains exceptionally high. Low settings deliver an average of 220.6 FPS, Medium produces 190.7 FPS, and High reaches 161.9 FPS. The Ultra preset still maintains a robust 129.7 FPS. The resolution increase from 1080p to 1440p exacts a predictable toll: at Ultra, the frame rate drops by 75.6 FPS, representing a 36.8% reduction. At Low, the drop is 118.8 FPS, a 35.0% reduction. The consistency of these percentage losses indicates that the GPU is the primary scaling factor, with the CPU not imposing a meaningful bottleneck at either resolution.

At 3840x2160, the system continues to deliver playable frame rates across all presets, though the margins narrow considerably. Low settings produce 120.2 FPS, Medium yields 104.2 FPS, and High achieves 86.4 FPS. The Ultra preset falls to 71.3 FPS, which is the lowest recorded average in the entire dataset. The scaling from 1440p to 4K shows a larger relative drop: Ultra loses 58.4 FPS (45.0%), while Low loses 100.4 FPS (45.5%). The fact that even 4K Ultra stays above 70 FPS confirms that this hardware combination has substantial headroom for this particular title.

Similar Performance Alternatives

The Intel Core i5-12400 sits in a narrow performance band according to its average benchmark score of 18683. The nearest rival is the AMD EPYC 7643, which scores 18697, a delta of just -0.1%. This places the two processors essentially at parity, meaning a system built around the EPYC 7643 would deliver nearly identical CPU-bound performance in Doom. The Intel Core i7-1355U scores 18730, which is 0.3% higher, again a negligible difference. The AMD Ryzen AI 5 330 comes in at 18811, 0.7% above the i5-12400. On the other side, the Intel Core i3-14100F scores 18519, which is 0.9% lower. These deltas are all under one percent, indicating that the CPU choice among these four options would not produce discernible frame rate differences in a GPU-bound scenario like this one.

On the GPU side, the NVIDIA GeForce RTX 5070 has an average benchmark score of 40377. The closest rival is the AMD Radeon Pro 580 at 40318, a delta of 0.1% in favor of the RTX 5070. The AMD Radeon Pro WX 7100 scores 40063, which is 0.8% lower, while the AMD Radeon Pro 5300 scores 40870, 1.2% higher. The NVIDIA RTX A500 Mobile trails at 39568, a 2.0% deficit. These relatively tight margins suggest that swapping the RTX 5070 for any of these alternatives would produce frame rate shifts of only a few percent, well within the noise of real-world gameplay variation. For Doom specifically, the measured FPS at 4K Ultra is 71.3, so a 2% difference would move that figure to roughly 70 or 73 FPS, still comfortably above the 60 FPS threshold.

CPU and GPU Roles

The benchmark data reveals a clear pattern: the GPU is the dominant performance factor at all tested resolutions, but the CPU's role becomes proportionally more significant as resolution decreases. At 3840x2160, the frame rate drops of 45.0-45.5% from 1440p indicate that the rendering workload scales directly with pixel count, a classic sign of GPU-bound operation. The CPU has ample time to prepare frames while the GPU works through the 8.3 million pixels per frame.

At 2560x1440, the GPU remains the bottleneck, but the CPU's influence grows. The frame rates at this resolution range from 129.7 FPS at Ultra to 220.6 FPS at Low, meaning the CPU must feed the GPU at rates exceeding 200 frames per second on lower presets. The i5-12400, with 6 cores and 12 threads, handles this without issue, but the data shows the scaling from 1440p to 1080p is not perfectly proportional to pixel count. At 1080p, the Ultra preset delivers 205.3 FPS, which is only 58.3% higher than the 129.7 FPS at 1440p Ultra, despite the pixel count being 56.3% lower. This non-linear scaling suggests the CPU begins to constrain frame generation at the lowest resolution, particularly on lighter presets where the GPU finishes work quickly.

The Low preset at 1080p producing 339.4 FPS is telling. This figure represents the practical ceiling of this combination, likely limited by the CPU's single-thread performance and the game's engine loop rather than the GPU. The Cinebench R23 single-core score of 2257 and Geekbench single-core score of 1848 for the i5-12400 are respectable, but they cap how fast the CPU can submit draw calls and update game state. Users chasing maximum frame rates at 1080p with competitive settings would find the GPU has no further headroom to offer, as the CPU becomes the limiting factor.

Best Settings per Resolution

At 1920x1080, the Ultra preset is the best choice, delivering an average of 205.3 FPS. This is far above the 60 FPS threshold, leaving immense headroom for high refresh rate displays. Even the most demanding settings do not meaningfully stress this combination at 1080p.

At 2560x1440, Ultra settings remain the optimal selection, with an average of 129.7 FPS. This comfortably exceeds 60 FPS and also clears 120 FPS, making it suitable for high refresh rate 1440p monitors. The gap between Ultra and the next preset down (High at 161.9 FPS) is 32.2 FPS, but the visual quality gain from Ultra is worth the reduction.

At 3840x2160, Ultra settings produce an average of 71.3 FPS, which is the only resolution where the margin above 60 FPS narrows to a single-digit percentage. While Ultra is still the best setting that stays above 60 FPS, users with variable refresh rate displays may notice occasional dips near heavy combat. The High preset at 86.4 FPS provides a 15.1 FPS buffer with only modest visual concessions, making it a safer choice for 4K gaming.

How This Combo Ranks

Among all tested hardware combinations in the database for Doom, this pairing of Intel Core i5-12400 and NVIDIA GeForce RTX 5070 ranks 669th out of 3712 total combinations. This places it in the top 18.0% of all tested systems, a strong showing that reflects the RTX 5070's high-end positioning. The GPU alone sits at the 82nd percentile among all GPUs, while the CPU is at the 72nd percentile among all CPUs. The combination's rank is slightly lower than the GPU's percentile would suggest, likely because Doom is not particularly CPU-intensive at higher resolutions, meaning slower CPUs paired with the same GPU would produce similar results. The 669th rank indicates that roughly 18% of tested combinations outperform this system, but those combinations typically feature more expensive processors or higher-tier GPUs. For a mid-range CPU paired with a current-generation high-end GPU, this ranking is consistent with expectations.

The Verdict

This PC can run Doom with complete confidence at every tested resolution and preset. The verdictByResolution data confirms that all four settings levels — Low, Medium, High, and Ultra — are playable at 1920x1080, 2560x1440, and 3840x2160. The best settings at each resolution are Ultra, with average FPS of 205.3 at 1080p, 129.7 at 1440p, and 71.3 at 4K.
