# Intel Core i5-12400 + NVIDIA GeForce RTX 4080: Doom Benchmark Analysis
The combination of the Intel Core i5-12400 and the NVIDIA GeForce RTX 4080 delivers a high-refresh-rate 4K experience in Doom. At 3840x2160, the measured average of 85 FPS at Ultra settings places this pairing firmly above the 60 FPS playability threshold, with enough headroom for GPU driver overhead or background tasks. The data indicates that the CPU is not the limiting factor at 4K; the GPU carries the rendering load effectively.
Measured FPS Breakdown
The FPS measurements are organized by resolution and preset. Each entry lists the average, and where available the minimum and maximum observed values.
3840x2160 (4K):
- Low: 141 FPS average. This preset is the least demanding at this resolution, and the GPU is underutilized, as the CPU can feed frames easily.
- Medium: 123 FPS average, with a spread from 104 to 141 FPS. The variance comes from scene complexity, but the average is well above the 60 FPS threshold.
- High: 104 FPS average. This is the most demanding of the four presets at 4K; the average stays above 100 FPS, indicating excellent scaling.
- Ultra: 85 FPS average. The Ultra preset at 4K is the most visually demanding and the data shows a 19% drop from Medium, but the experience remains fluid.
2560x1440 (1440p):
- Low: 260 FPS average. The GPU is not the bottleneck; the CPU at this resolution still feeds frames rapidly.
- Medium: 226 FPS average, with a minimum of 192 and a maximum of 260 FPS. This is a 13% reduction from Low, which is a relatively small penalty.
- High: 191 FPS average. At this resolution, the preset scales well and the average remains nearly 2x the 4K High result.
- Ultra: 156 FPS average. The Ultra preset at 1440p is the most demanding here; the 156 FPS average is still 2.6x the 60 FPS threshold.
1920x1080 (1080p):
- Low: 363 FPS average. At 1080p, the CPU begins to matter more; the Core i5-12400's six performance cores handle the game logic easily.
- Medium: 345 FPS average, with a range of 294 to 397 FPS. The variance is wider at this resolution due to the CPU becoming a more active participant.
- High: 295 FPS average. The GPU remains dominant, but the percent difference from Medium is 14%, which is smaller than at higher resolutions.
- Ultra: 241 FPS average. At 1080p, the Ultra preset is the most demanding. The 241 FPS average is 30% below High, but it remains far beyond the 60 FPS target.
CPU and GPU Roles
The division of labor between the Intel Core i5-12400 and the NVIDIA GeForce RTX 4080 shifts with resolution. At 1920x1080, the CPU is more relevant than at 4K.
The data shows a clear scaling pattern. Going from 1080p to 1440p, the High preset drops from 295 to 191 FPS, a 35% reduction. From 1440p to 4K, High drops from 191 to 104 FPS, another 46%. This indicates that the rasterization load scales super-linearly with pixel count, and the RTX 4080 is the primary component handling this.
At 1080p, the Core i5-12400 can feed frames at 363 FPS at Low, but the GPU caps the output at 241 FPS at Ultra. This shows the GPU is the limiting factor even at the lowest resolution. At 4K, the CPU's role diminishes; the GPU's shading rate and memory bandwidth dictate the frame rate.
Similar Performance Alternatives
The nearest rivals to this pairing, based on aggregate benchmark scores, are the AMD EPYC 7643, the Intel Core i7-1355U, the AMD Ryzen AI 5 330, and the Intel Core i3-14100F.
The AMD EPYC 7643 has an average score of 18,697, which is 0.1% lower than the Core i5-12400's 18,683. In gaming, the EPYC's higher core count helps in CPU-bound scenes, but the RTX 4080 is the same GPU, so the FPS output would be nearly identical. The difference lies in physics and draw-call-heavy scenes, where the EPYC's extra cores can maintain frame pacing better.
The Intel Core i7-1355U averages 18,730, 0.3% higher. Its two performance cores in the Alder Lake architecture are enough for this game. At lower resolutions, this CPU would behave similarly. The 1355U has a lower TDP, but the RTX 4080's frame generation at 4K with Ultra is still the limiting factor.
The AMD Ryzen AI 5 330 scores 18,811, 0.7% higher. The Ryzen AI's integrated RDNA 3 graphics do not compete with the discrete RTX 4080, but the CPU's six Zen 4 cores are sufficient at 1080p. At 4K, the GPU bound workload makes the CPU difference negligible.
The Intel Core i3-14100F scores 18,519, 0.9% lower. This is the closest rival. The i3's four cores are enough for Doom's engine, but the RTX 4080 is still the deciding component. Users with this CPU and the same GPU should expect within 1% frame rate parity.
FAQ
Q: Does the Core i5-12400 bottleneck the RTX 4080 at 1080p?
A: No. At 1920x1080 Low, the average is 363 FPS, and at Ultra it is 241 FPS. The CPU does not bottleneck the RTX 4080. The 6 P-cores of the i5-12400 are sufficient for the engine's draw call submission.
Q: Is the Ultra preset at 4K playable?
A: Yes. The Ultra preset at 3840x2160 averages 85 FPS. This is well above the 60 FPS threshold. The 34% reduction from High to Ultra at 4K is the largest preset penalty in the data, but the average remains fluid.
Q: How much faster is 1440p compared to 4K?
A: The High preset at 2560x1440 averages 191 FPS, which is 84% higher than the same preset at 3840x2160. This is due to the pixel count being 2.25x smaller, reducing the shading load on the GPU.
Q: Which is the most demanding preset at 1080p?
A: The Ultra preset at 1920x1080 averages 241 FPS. This is the lowest average among the four presets at this resolution, but it is still 4x the 60 FPS threshold.
Q: Is the Ultra preset at 4K above 60 FPS?
A: Yes. The average FPS at 3840x2160 Ultra is 85. The 4K Ultra preset is the most demanding setting among the tested combinations, but it stays 42% above the 60 FPS playability line.
Q: How do the Medium and Low presets compare at 1440p?
A: At 2560x1440, Medium averages 226 FPS while Low averages 260 FPS. That is a 13% difference, which is within the run-to-run variation of the test.
Best Settings per Resolution
- 3840x2160: The most demanding preset that stays above 60 FPS is Ultra. It averages 85 FPS. Ultra is the recommended setting for this resolution.
- 2560x1440: The most demanding tested preset is Ultra, averaging 156 FPS, safely above 60.
- 1920x1080: The Ultra preset is the most demanding and averages 241 FPS, which is 4x the 60 FPS threshold.
How This Combo Ranks
The Core i5-12400 + RTX 4080 pairing holds rank 298 out of 3,712 tested combos in the benchmark database. This places it in the upper 8% of all tested configurations. The nearest rival, the AMD EPYC 7643 plus the same GPU, is 0.1% slower on average. The rank is driven more by the GPU than the CPU, as the RTX 4080's scoring lifts the combo above most others.
The Verdict
Can this PC run Doom? Yes. The data confirms this configuration plays Doom at 60+ FPS at every tested resolution, including 4K with the Ultra preset. The Intel Core i5-12400 and NVIDIA GeForce RTX 4080 combination is a high-refresh-rate 1440p machine and a capable 4K performer. The weakest point is the CPU at 1080p low presets, where the i5's six P-cores are still enough to feed the RTX 4080. For the highest fidelity experience, the Ultra preset at 3840x2160 is recommended; 85 FPS average is the most demanding tested setting and it clears the threshold by a wide margin.
