Doom

The Intel Core i7-14700KF paired with the NVIDIA GeForce RTX 4080 SUPER delivers extreme performance in Doom, clearing the 60 FPS threshold with substantial headroom at every resolution and setting combination tested. The data shows a system that is heavily GPU-bound at higher resolutions but maintains such high frame rates that the distinction rarely matters for playability.

Best Settings per Resolution

At 3840x2160 (4K), the most demanding preset that stays at or above 60 FPS is Ultra, which achieves an average of 86.3 FPS. This is the highest quality setting available, and the system still has 26.3 FPS of headroom above the playable threshold. The High preset runs at 106.1 FPS, Medium at 119.4 FPS, and Low at 139.1 FPS, but since Ultra exceeds the threshold comfortably, it is the recommended choice for maximum visual fidelity.

At 2560x1440 (1440p), the best settings are again Ultra, with an average of 155.4 FPS. This is nearly 2.6 times the 60 FPS threshold, indicating that even the most demanding preset leaves massive performance reserves. The scaling from High to Ultra costs 37.0 FPS (from 192.4 to 155.4), but the result remains far beyond what is needed for smooth gameplay.

At 1920x1080 (1080p), the Ultra preset delivers an average of 239.7 FPS, which is exactly four times the playable threshold. This is the highest frame rate of any resolution at Ultra settings, and the data shows that Low settings reach 400.2 FPS, Medium hits 348.5 FPS, and High runs at 291.9 FPS. At this resolution, the system is so far ahead of the 60 FPS requirement that the choice of preset is purely a matter of preference between visual quality and refresh-rate headroom.

Across all three resolutions, the verdict is consistent: the Ultra preset is always the best choice because it clears the threshold by a wide margin. There is no scenario where the user must compromise on settings to achieve playability.

CPU and GPU Roles

The data indicates a clear pattern where the GPU becomes more influential as resolution increases, while the CPU’s role is more prominent at lower resolutions. At 1920x1080, the difference between Low and Ultra settings is 160.5 FPS (from 400.2 down to 239.7), which is a 40.1% drop. This large delta suggests that the CPU is capable of feeding the GPU with enough data to reach extremely high frame rates, but the GPU is still the limiting factor when settings are maxed out.

At 2560x1440, the spread between Low and Ultra narrows to 101.9 FPS (from 257.3 down to 155.4), a 39.6% reduction. The absolute numbers are lower than at 1080p, which is expected because the GPU must render more pixels. The percentage drop is nearly identical, indicating that the relative load shift between CPU and GPU is consistent as resolution scales.

At 3840x2160, the gap between Low and Ultra shrinks further to 52.8 FPS (from 139.1 down to 86.3), a 38.0% reduction. The frame rates are significantly lower than at 1440p, showing that the GPU is now the dominant constraint. The CPU’s 20 cores and 28 threads are more than sufficient to keep up with the GPU’s rendering workload at 4K, but the GPU’s fill rate and memory bandwidth become the deciding factors.

The scaling between resolutions at the same preset reinforces this analysis. At Ultra settings, moving from 1080p to 1440p reduces the average FPS by 84.3 (from 239.7 to 155.4), a 35.2% drop. Moving from 1440p to 4K reduces it by another 69.1 FPS (from 155.4 to 86.3), a 44.5% drop. This larger relative drop at the highest resolution confirms that the RTX 4080 SUPER’s 16 GB of GDDR6X memory and 736.3 GB/s bandwidth are being taxed more heavily, while the CPU’s role diminishes.

FAQ

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

A: Yes, the Ultra preset at 3840x2160 averages 86.3 FPS, which is above the 60 FPS playable threshold. All four settings (Low, Medium, High, Ultra) are playable at this resolution.

Q: What is the fastest frame rate this combo achieves?

A: The highest measured average is 400.2 FPS at 1920x1080 with Low settings. This is the only configuration that exceeds 400 FPS.

Q: How much performance is lost when moving from 1440p to 4K at Ultra settings?

A: At Ultra, the average FPS drops from 155.4 at 2560x1440 to 86.3 at 3840x2160, a reduction of 69.1 FPS or 44.5%.

Q: Is the CPU or GPU more important for this game?

A: The GPU is the primary constraint at 4K, as shown by the 38.0% difference between Low and Ultra settings. At 1080p, the CPU’s 20 cores and 28 threads allow for very high frame rates, but the GPU still limits Ultra settings to 239.7 FPS.

Q: Are there any settings that fail to reach 60 FPS?

A: No. Every combination of resolution (1920x1080, 2560x1440, 3840x2160) and settings (Low, Medium, High, Ultra) exceeds 60 FPS. The lowest average is 86.3 FPS at 4K Ultra.

Q: How does the RTX 4080 SUPER compare to the RTX 4080 in this context?

A: The RTX 4080 SUPER has an average benchmark score of 54209, while the RTX 4080 scores 54247, a delta of -0.1%. This means the SUPER is effectively identical in performance to the non-SUPER variant, so frame rates would be nearly indistinguishable.

Similar Performance Alternatives

For the CPU, the nearest rivals are all extremely close in average benchmark score. The AMD Ryzen 7 9700F scores 69996, just 0.2% lower than the Core i7-14700KF’s 70163. The AMD Ryzen 9 7940HX is 0.4% lower at 69875, and the AMD Ryzen 9 7950X is 0.9% lower at 69515. The Intel Core Ultra 7 265K is the only rival that scores higher, at 70879, which is 1.0% above. None of these differences would produce a measurable change in Doom’s frame rates, as the game is not CPU-limited at any tested resolution.

For the GPU, the NVIDIA GeForce RTX 4080 is the closest match, with an average score of 54247 versus 54209 for the RTX 4080 SUPER, a delta of -0.1%. The AMD Radeon Pro W5700X scores 54828 (1.1% higher), and the AMD Radeon RX 6750 GRE 12 GB scores 55698 (2.7% higher). The AMD Radeon 8060S is 2.8% higher at 55757. These differences are within a few percent, meaning that any of these GPUs would deliver nearly identical performance in Doom, with the RTX 4080 being the most direct equivalent.

The practical implication is that users with any of these CPUs or GPUs can expect similar results. The Core i7-14700KF’s 94th percentile ranking among all CPUs and the RTX 4080 SUPER’s 86th percentile among all GPUs place both components in the upper tier, but the near-identical rival scores mean there is no single dominant choice in this performance band.

Measured FPS Breakdown

At 1920x1080, the full range of settings shows the system’s headroom. Low settings produce an average of 400.2 FPS, which is the highest recorded value. Medium settings drop to 348.5 FPS, a 12.9% reduction. High settings run at 291.9 FPS, and Ultra settings produce 239.7 FPS. The step from Low to Ultra represents a 40.1% performance penalty, but even the lowest value is nearly four times the 60 FPS threshold.

At 2560x1440, the same pattern holds with lower absolute numbers. Low settings average 257.3 FPS, Medium runs at 227.5 FPS, High at 192.4 FPS, and Ultra at 155.4 FPS. The drop from Low to Ultra is 39.6%, which is nearly identical to the 1080p percentage, indicating that the GPU’s workload scales consistently with pixel count.

At 3840x2160, the frame rates are the lowest but still far above the threshold. Low settings average 139.1 FPS, Medium runs at 119.4 FPS, High at 106.1 FPS, and Ultra at 86.3 FPS. The difference between Low and Ultra is 38.0%, which is slightly smaller than at lower resolutions. This suggests that at 4K, the GPU’s raw compute and memory bandwidth are being saturated, and the relative cost of higher settings diminishes as the resolution becomes the dominant factor.

Across all resolutions, the data shows a consistent pattern: each step up in settings costs roughly 15-25% of the previous frame rate, and each step up in resolution costs a similar percentage. The system never approaches the 60 FPS floor, with the smallest margin being 26.3 FPS at 4K Ultra.

The Verdict

This PC can run Doom at every resolution and setting combination tested, with no exceptions. At 3840x2160, all four presets are playable, and the best settings are Ultra with an average of 86.3 FPS. At 2560x1440, Ultra runs at 155.4 FPS, and at 1920x1080, Ultra runs at 239.7 FPS. The verdict by resolution is unambiguous: the system clears the 60 FPS threshold at all settings, making it suitable for high-refresh-rate monitors at 1080p and 1440p, and for 4K displays with maximum quality.

The only consideration is that the RTX 4080 SUPER is marked as end-of-life, and its successor, the GeForce 50 series, has been released. However, the measured data shows that this is not a practical concern for Doom, as the current hardware has massive performance reserves. The GPU’s 52.22 TFLOPS of FP32 compute and 16 GB of GDDR6X memory are more than adequate for this 2016 title.

How This Combo Ranks

The Intel Core i7-14700KF and NVIDIA GeForce RTX 4080 SUPER combination ranks 251st out of 3712 tested combos in Doom. This places it in the top 6.8% of all tested systems. The rank reflects the GPU’s 86th percentile standing and the CPU’s 94th percentile standing, though the game’s low system requirements mean that even mid-range hardware can achieve high frame rates.

The ranking is driven primarily by the GPU’s strong absolute performance, as the CPU’s high multi-threaded scores (44167 in Cinebench R23 multicore) are not fully utilized by Doom’s engine. The 251st position out of 3712 combos indicates that there are 250 systems with higher measured performance, but these are likely to feature even more powerful GPUs or higher-clocked CPUs. For practical purposes, this combo is firmly in the top tier of Doom performance, and the data shows no scenario where it falls short of the playable threshold.
