Doom

The Intel Core i5-12400 and NVIDIA GeForce RTX 4080 SUPER combination delivers exceptionally high frame rates in Doom, with the data showing that every tested preset at every resolution clears the 60 FPS playable threshold by a wide margin. The pairing of a 72nd-percentile CPU with an 86th-percentile GPU produces results that are not merely playable but overwhelmingly fast, positioning this system as an extreme outlier in performance for this 2016 title.

Similar Performance Alternatives

The CPU and GPU each have near-neighbor rivals that would produce virtually indistinguishable results in this system. For the processor, the Intel Core i5-12400 posts an average benchmark score of 18683, sitting within 0.9% of four nearby alternatives. The AMD EPYC 7643 scores 18697, a delta of -0.1%, meaning it would behave nearly identically in CPU-bound scenarios. The Intel Core i7-1355U trails by 0.3% with a score of 18730, while the AMD Ryzen AI 5 330 is 0.7% behind at 18811. On the other side, the Intel Core i3-14100F scores 18519, which is 0.9% lower than the i5-12400. These deltas are so small that any of these processors would yield the same FPS in Doom, where the GPU dominates the workload.

On the graphics side, the RTX 4080 SUPER achieves an average benchmark score of 54209, and its nearest rival is the standard NVIDIA GeForce RTX 4080 with a score of 54247, a negligible -0.1% difference. The AMD Radeon Pro W5700X scores 54828, putting it 1.1% ahead, while the AMD Radeon RX 6750 GRE 12 GB is 2.7% ahead at 55698, and the AMD Radeon 8060S leads by 2.8% at 55757. In practice, swapping the RTX 4080 SUPER for any of these cards would produce frame rates within a few percent of each other, meaning the overall gaming experience at 60 FPS or beyond would remain unchanged. The data suggests that this system's performance envelope is shared by a cluster of high-end components, all of which would handle Doom with similar ease.

CPU and GPU Roles

The benchmark data reveals that the GPU is the overwhelming performance driver in Doom, with CPU influence being almost negligible at the tested resolutions. At 1920x1080, the lowest resolution, the CPU has the most relative impact, yet the frame rates are so high that the processor never becomes a bottleneck. The i5-12400's single-thread score of 910 in 3dmark and its 72nd percentile ranking among all CPUs indicate it is more than sufficient for this game's demands. The scaling from Low to Ultra at 1080p shows a drop from 360.8 FPS to 242.6 FPS, a 32.8% reduction, which is entirely attributable to GPU load increasing with visual complexity.

As resolution increases, the GPU's role becomes even more dominant. Moving from 1920x1080 to 2560x1440 at Ultra settings reduces the average FPS from 242.6 to 157.3, a 35.2% decline, while the CPU workload stays constant. At 3840x2160, the Ultra preset yields 85.4 FPS, which is 64.8% lower than the 1080p Ultra result. This steep drop-off is a classic sign of GPU-bound rendering, where the RTX 4080 SUPER's 52.22 TFLOPS of FP32 compute and 736.3 GB/s of memory bandwidth are the limiting factors, not the 6-core, 12-thread processor. The data implies that at 4K, the CPU is essentially idle relative to the GPU, and even a significantly weaker processor would not reduce these frame rates.

Measured FPS Breakdown

At 1920x1080, the system produces staggering results across all presets. The Low preset averages 360.8 FPS, which is the highest recorded value in the entire dataset. Medium settings deliver 344.7 FPS, while High drops to 294.7 FPS. The Ultra preset still averages 242.6 FPS, which is more than four times the 60 FPS playable threshold. The spread from Low to Ultra is 118.2 FPS, indicating that visual quality settings have a substantial impact even at this resolution, but the absolute performance remains far beyond what any display can practically show.

At 2560x1440, the frame rates remain exceptionally high. Low settings produce 260 FPS, Medium 224.2 FPS, High 188.7 FPS, and Ultra 157.3 FPS. The drop from Low to Ultra is 102.7 FPS, a similar relative reduction to 1080p. The difference between 1080p and 1440p at the same settings is consistent, with Ultra losing 85.3 FPS when moving up in resolution. This scaling suggests that the RTX 4080 SUPER's 16 GB of GDDR6X memory and 256-bit bus are more than adequate for the increased pixel count.

At 3840x2160, the system still delivers well above 60 FPS on every preset. Low averages 138.1 FPS, Medium 122.8 FPS, High 102.1 FPS, and Ultra 85.4 FPS. The gap between Low and Ultra is 52.7 FPS, which is proportionally smaller than at lower resolutions, indicating that the GPU is becoming more constrained. The 4K Ultra result of 85.4 FPS is still 42.4% above the playable threshold, leaving significant headroom for demanding scenes. Notably, the data shows no min or max FPS values, only averages, so frame-time consistency cannot be assessed from this pack.

The Verdict

This PC can run Doom at any resolution and preset combination tested, with all twelve measured scenarios exceeding the 60 FPS playable threshold. At 3840x2160, the verdict is unequivocal: High, Low, Medium, and Ultra settings are all playable, with Ultra averaging 85.4 FPS. This is the most demanding configuration in the dataset, and it still clears the threshold by 25.4 FPS. At 2560x1440, the system achieves 157.3 FPS on Ultra, which is 162% of the 60 FPS target, making it suitable for high-refresh-rate monitors. At 1920x1080, the Ultra preset averages 242.6 FPS, which is ideal for 240 Hz displays.

The verdictByResolution data confirms that no settings need to be compromised. Every resolution and preset combination is rated as playable, and the best settings at each resolution are the highest quality ones. The 4K Ultra result of 85.4 FPS is particularly notable because it demonstrates that this combination can push maximum visual fidelity at 4K while remaining comfortably above the playable threshold. For a game released in 2016, this hardware is massively overprovisioned, but the data shows no signs of CPU bottlenecking or memory limitations.

How This Combo Ranks

The combo ranks 306th out of 3712 tested combinations in Doom, placing it in the top 8.2% of all systems evaluated. This is a strong result, though not the absolute top, which suggests that there are 305 combinations that perform better. Given that the RTX 4080 SUPER sits at the 86th percentile among all GPUs and the i5-12400 at the 72nd percentile among CPUs, the rank of 306 is consistent with a high-end but not flagship pairing. The ranking implies that many systems with more powerful CPUs, such as those with higher single-thread scores, achieve even higher frame rates, particularly at lower resolutions where processor performance matters more.

The rank also reflects that Doom is not a particularly demanding title for modern hardware. The 85.4 FPS at 4K Ultra indicates that even mid-range GPUs could likely hit 60 FPS at this resolution, so the top 8.2% ranking is more a signal of the raw power of the RTX 4080 SUPER than to any optimization. The data shows that the i5-12400's 15989 Cinebench R23 multicore score and 2257 single-core score are sufficient to keep up with the GPU, but they are not the reason for the high rank. The GPU's 34245 Passmark G3D score and 52.22 TFLOPS are the primary contributors.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 242.6 FPS. This is the highest quality setting available, and it delivers more than four times the playable threshold. There is no reason to reduce settings at this resolution, as even the most demanding preset provides massive headroom.

At 2560x1440, the Ultra preset is also the best choice, averaging 157.3 FPS. This is 97.3 FPS above the 60 FPS threshold, so players can enable every visual feature without concern. The data shows that Medium and High settings are also playable, but they offer no advantage since Ultra already performs so well.

At 3840x2160, the Ultra preset remains the best option, with an average of 85.4 FPS. This is 25.4 FPS above the playable threshold, providing a comfortable margin for demanding scenes. The data indicates that High, Medium, and Low are also playable, but they would only be necessary if the player prefers higher frame rates over maximum visual quality. Since Ultra already clears 60 FPS, it is the recommended setting at all three resolutions.
