Doom

This combo—an Intel Core i5-12400F paired with an NVIDIA GeForce RTX 5080—is a study in GPU-bound scaling. The data shows that the CPU, while ranking in the 73rd percentile against all tested processors, is not the limiting factor here. Instead, the RTX 5080, sitting in the 87th percentile of all GPUs, drives frame rates so high that the game becomes a test of pure rasterization throughput. Across all three resolutions (1080p, 1440p, and 4K), every preset from Low to Ultra clears the 60 FPS playable threshold with substantial headroom, making this a system that can run Doom at maximum settings without compromise.

FAQ

Q: Can this PC run Doom at 4K with maximum settings?

A: Yes. The measured data shows an average of 91.6 FPS at 3840x2160 with the Ultra preset, which is well above the 60 FPS playable threshold. This is the best settings option at that resolution, and it still leaves over 50% performance headroom.

Q: What is the performance difference between Low and Ultra settings at 1440p?

A: At 2560x1440, the Low preset achieves 277.5 FPS, while the Ultra preset reaches 168.1 FPS. That is a drop of 109.4 FPS, or roughly 39% lower performance, but the Ultra score remains nearly three times the 60 FPS threshold.

Q: How does this combo rank among all tested CPU-GPU combinations?

A: The combo ranks 193rd out of 3712 tested combinations, placing it in the top 5.2% of all systems in the benchmark database for this game. This high relative ranking reflects the GPU's strong percentile score.

Q: Is the CPU or GPU more important for achieving high frame rates in Doom?

A: The GPU is the dominant factor. The RTX 5080 has a passmark G3D score of 36565, while the CPU's best multi-thread benchmark (Cinebench R23) is 12380. The massive GPU compute advantage explains why frame rates scale more with resolution and preset changes than with CPU-bound tasks.

Q: What is the lowest frame rate recorded in the entire benchmark set?

A: The lowest average FPS is 91.6, which occurs at 3840x2160 with the Ultra preset. Even this most demanding configuration never dips below the playable threshold, indicating consistent performance across all tested scenarios.

Q: Does the CPU's single-thread performance bottleneck the GPU at 1080p?

A: No. At 1920x1080 with Low settings, the system hits 365.5 FPS. The CPU's single-thread score of 3481 in Passmark and 909 in 3DMark is sufficient to feed the GPU even at these extreme frame rates, as evidenced by the fact that no preset at 1080p drops below 254.2 FPS.

CPU and GPU Roles

Examining the measured FPS data reveals a clear pattern: the RTX 5080 is the performance driver, while the i5-12400F provides sufficient support without becoming a bottleneck. At 1920x1080, moving from Low to Ultra settings reduces frame rates from 365.5 to 254.2 FPS—a 30.5% decrease. This settings sensitivity is a classic sign of GPU-bound rendering, as the graphics card's workload increases with each quality tier.

The resolution scaling further confirms the GPU's dominance. Dropping from 1440p to 1080p at Ultra settings improves performance from 168.1 to 254.2 FPS, a 51.2% gain. Similarly, moving from 4K to 1440p at Ultra jumps from 91.6 to 168.1 FPS, an 83.5% improvement. These are massive gains driven entirely by pixel count reduction, which is the GPU's primary workload. The CPU's role is consistent across all resolutions—it maintains high thread utilization without creating a ceiling.

At 4K, the gap between presets narrows in relative terms. The Low preset runs at 147.9 FPS, while Ultra runs at 91.6 FPS. This 56.3 FPS difference is smaller than the 111.3 FPS gap seen at 1080p between the same presets. This behavior is typical of GPU-limited scenarios: as resolution increases, the GPU becomes even more saturated, and settings changes have a smaller proportional impact. The CPU, with its 6 cores and 12 threads, never appears in the data as a limiting factor, as even the most CPU-light scenario (4K Low) produces frame rates far above the playable threshold.

Best Settings per Resolution

At 1920x1080, the Ultra preset delivers 254.2 FPS, which is the most demanding configuration tested and it stays far above 60 FPS. There is no reason to lower settings at this resolution, as even the heaviest load still provides over four times the playable threshold.

At 2560x1440, the Ultra preset achieves 168.1 FPS. This is the best visual quality option, and it maintains nearly three times the 60 FPS target. The data shows no need to compromise on settings, as the gap between Ultra and High (201.8 FPS) is only 33.7 FPS, but Ultra is already comfortably playable.

At 3840x2160, the Ultra preset runs at 91.6 FPS. This is the most demanding scenario in the entire dataset, yet it still clears the 60 FPS threshold by 31.6 FPS. All four presets—Low at 147.9, Medium at 128.9, High at 112.5, and Ultra at 91.6—are playable, but Ultra offers the best image quality without sacrificing the 60 FPS requirement.

Similar Performance Alternatives

Looking at the nearestRivals data, the CPU's closest competitor is the AMD Ryzen 5 7535HS, which has an identical average benchmark score (19047 vs 19039, a 0% delta). This laptop-class chip performs essentially the same as the i5-12400F in synthetic tests, meaning a system with that CPU would produce nearly identical frame rates in Doom, assuming the same GPU.

The Intel Core 3 201E is 0.1% slower than the i5-12400F, while the Intel Core i5-1335U is 0.3% faster, and the AMD EPYC 7773X is also 0.3% faster. These deltas are negligible in real-world gaming, so any of these CPUs paired with an RTX 5080 would land within a few FPS of this combo's results.

On the GPU side, the AMD Radeon 8060S is the closest rival, with an average score of 55757 versus the RTX 5080's 56083—a 0.6% deficit. The AMD Radeon RX 6750 GRE 12 GB trails by 0.7%, while the AMD Radeon Pro W5700X is 2.3% behind. Interestingly, the AMD Radeon RX 9070 GRE is 2.2% faster than the RTX 5080 in average score. In practical terms, swapping the RTX 5080 for any of these cards would change Doom's frame rates by only a few percent, keeping all resolutions and presets well above 60 FPS.

How This Combo Ranks

The comboRankInGame places this specific CPU-GPU pairing at 193rd out of 3712 tested combinations. This top 5.2% ranking is notable because it reflects the entire system's capability, not just the GPU. Many higher-ranked combinations likely feature more expensive CPUs, but the i5-12400F proves sufficient for this game's demands.

The ranking makes sense when considering the individual component percentiles. The RTX 5080 sits at the 87th percentile among all GPUs, while the i5-12400F is at the 73rd percentile among CPUs. The combination of a top-tier GPU with a mid-range CPU results in a system that ranks higher than the CPU's percentile alone would suggest, because Doom's performance is overwhelmingly GPU-dependent. The data indicates that this combo outperforms 94.8% of all tested systems, making it a high-end configuration for this title.

The Verdict

This PC can run Doom at every resolution and preset combination tested, with substantial margin above the 60 FPS playable threshold. At 1920x1080, the Ultra preset delivers 254.2 FPS; at 2560x1440, Ultra runs at 168.1 FPS; and at 3840x2160, Ultra maintains 91.6 FPS. The verdictByResolution data confirms that all settings—Low, Medium, High, and Ultra—are playable at all three resolutions.

The weakest performance point in the entire dataset is 4K Ultra at 91.6 FPS, which is still over 50% faster than the 60 FPS minimum. This means users can max out every graphics option without worrying about frame rate drops. The RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth provide ample headroom for high-resolution textures, while the i5-12400F's six cores and twelve threads handle the game's engine overhead efficiently. For Doom specifically, this combination offers no compromises—it is a system where the GPU is the clear star, and the CPU quietly supports it without ever becoming a limitation.
