Doom

The pairing of an Intel Core i5-14600KF with an NVIDIA GeForce RTX 4070 is a mid-to-high-end desktop combination from the 2023 hardware generation, and the measured data shows it handles Doom — the 2016 release in the long-running FPS series — with a wide margin at every tested resolution. This analysis covers the full set of measured frame rates, examines which component is the limiting factor at each resolution, and places the combo in context against other tested hardware pairings.

Measured FPS Breakdown

All results below are measured averages for the Core i5-14600KF + RTX 4070 configuration, tested at three resolutions with four presets each. Minimum and maximum frame rates were not captured for these runs, so the averages serve as the primary indicator.

At 1920x1080, the frame rates are far beyond what the 60 FPS playable threshold demands. Low settings average 315.1 FPS, Medium averages 275.7 FPS, High averages 232.4 FPS, and even Ultra averages 191.4 FPS. That is more than three times the playable threshold at the game's most demanding preset.

At 2560x1440, the numbers remain extremely strong. Low averages 202.8 FPS, Medium 178.2 FPS, High 152 FPS, and Ultra 119.4 FPS. Even the heaviest preset clears 60 FPS by nearly a factor of two.

At 3840x2160, the averages compress but stay above the threshold across the board: Low at 108.9 FPS, Medium at 97.8 FPS, High at 80.7 FPS, and Ultra at 67.1 FPS. Ultra at 4K sits only 7.1 FPS above the 60 FPS line, which is the narrowest margin anywhere in this dataset, but it is still a pass.

The spread between presets is also informative. Moving from Ultra to Low at 4K recovers 41.8 FPS (67.1 to 108.9), a substantial gain for players chasing higher refresh rates on a 4K display. At 1080p the same step recovers 123.7 FPS (191.4 to 315.1), reflecting how much headroom exists at that resolution.

CPU and GPU Roles

The scaling behavior between resolutions indicates that this game, on this hardware, is GPU-bound at every tested setting. Consider the Ultra preset: 191.4 FPS at 1920x1080, 119.4 FPS at 2560x1440, and 67.1 FPS at 3840x2160. Frame rate falls steadily as pixel count rises — dropping by 72 FPS from 1080p to 1440p and by a further 52.3 FPS from 1440p to 4K. That monotonic decline with resolution is the classic signature of a graphics-limited workload: if the Core i5-14600KF were the bottleneck, frame rates would plateau as resolution increased, and they do not.

The CPU's contribution should not be dismissed, however. Doom is a fast FPS, and maintaining frame pacing at rates approaching 300 FPS at low settings requires strong single-threaded throughput. The i5-14600KF posts a Cinebench R23 single-core score of 4594 and a Geekbench single-core score of 2445, placing it in the 90th percentile among all CPUs in the database — comfortably capable of feeding the game's simulation at these frame rates. Its multi-core credentials (Cinebench R23 multi-core at 32544, Passmark multithread at 38697) matter less here than single-thread performance, but they confirm the processor is never a plausible constraint at 4K, where the RTX 4070 does the governing.

Within a fixed resolution, the preset-to-preset scaling also points at the GPU. Dropping settings from Ultra to Low at 1440p lifts the average from 119.4 to 202.8 FPS — an 83.4 FPS gain purely from reducing GPU render load. The RTX 4070 sits in the 81st percentile of all GPUs, with a PassMark G3D score of 26927 and a Geekbench Vulkan score of 174152, and Vulkan is directly relevant since Doom renders through that API. In short: at 1080p and 1440p the GPU is near-saturated and the CPU has ample headroom; at 4K the GPU is decisively the limiting component.

FAQ

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

A: Yes. The measured average at 3840x2160 Ultra is 67.1 FPS, which clears the 60 FPS playable threshold. Every other 4K preset — High at 80.7, Medium at 97.8, and Low at 108.9 — clears it by a wider margin.

Q: Which resolution and preset combination gives the highest frame rate?

A: 1920x1080 at Low settings, averaging 315.1 FPS. This is the best result in the dataset and is suitable for very high refresh rate displays.

Q: Is the CPU or the GPU more important for Doom on this combo?

A: The GPU. Frame rates scale down consistently as resolution increases (191.4 → 119.4 → 67.1 FPS at Ultra), which indicates a graphics-bound workload. The i5-14600KF, in the 90th percentile of all CPUs, has headroom to spare at every tested setting.

Q: How much performance is lost going from 1440p to 4K at High settings?

A: The average drops from 152 FPS to 80.7 FPS — a loss of 71.3 FPS — but both remain comfortably playable.

Q: What CPU benchmark scores back up the claim that the processor keeps up?

A: The i5-14600KF records 4594 in Cinebench R23 single-core, 32544 in Cinebench R23 multi-core, 2445 in Geekbench single-core, and 4273 in PassMark single-thread, placing it in the 90th percentile of all CPUs in the database.

Q: Does any tested combination of resolution and preset fail the 60 FPS bar?

A: No. All twelve measured configurations — three resolutions across four presets — average above 60 FPS. The closest call is 4K Ultra at 67.1 FPS.

Similar Performance Alternatives

For the CPU, the nearest rivals by aggregate score are remarkably tight. The AMD Ryzen 9 7900 averages 49228 against the i5-14600KF's 49394 — a gap of just 0.3 percent — and the AMD Ryzen 7 PRO 5755G sits 0.4 percent behind at 49196. The Intel Core Ultra 5 245 trails by 0.8 percent at 48995, while the AMD Ryzen AI Max+ 388 actually scores slightly higher at 49796, 0.8 percent ahead. Any of these processors would deliver effectively indistinguishable Doom performance in this GPU-bound scenario, since differences of less than one percent in aggregate CPU score are far smaller than the GPU's influence on frame rate.

On the graphics side, the rivals cluster similarly close. The NVIDIA Tesla P4 averages 37628 versus the RTX 4070's 37648 — a 0.1 percent delta — and the AMD Radeon RX Vega 56 is 0.4 percent behind at 37507. The NVIDIA GeForce RTX 4080 Mobile scores 38135, putting it 1.3 percent ahead, and the AMD Radeon PRO W6400 trails by 1.3 percent at 37157. In practice, a system built around any of these GPUs would be expected to produce Doom frame rates within a small band of the numbers reported here, though the RTX 4070's Vulkan strength (Geekbench Vulkan score of 174152) remains directly relevant to this title.

How This Combo Ranks

Against the full database, the Core i5-14600KF + RTX 4070 pairing ranks 835th out of 3712 tested combinations in Doom. That places it in roughly the top 22.5 percent of all tested pairings for this game — a strong showing, though well short of the leaderboard's summit, which is occupied by flagship-class hardware. Given that every measured configuration clears 60 FPS, the ranking reflects the pursuit of high-refresh performance rather than mere playability: combos ranked above this one are those pushing Doom toward its highest possible frame rates at 1080p and 1440p, or holding higher averages at 4K. For a mid-to-upper-tier pairing, rank 835 of 3712 confirms the combo sits comfortably in the upper tier of tested systems for this title.

The Verdict

Yes — this PC runs Doom, and it does so without compromise. The verdict data shows all four presets marked playable at every one of the three tested resolutions, with Ultra identified as the best setting at each: 191.4 FPS average at 1920x1080, 119.4 FPS at 2560x1440, and 67.1 FPS at 3840x2160. Every one of those clears the 60 FPS threshold.

The one figure that warrants attention is 4K Ultra at 67.1 FPS. It is playable by the database's standard, but the 7.1 FPS margin above threshold is the slimmest in the dataset, and without minimum-frame data captured for these runs, demanding moments could dip below the average. Players wanting more cushion at 4K can step down one preset to High at 80.7 FPS. At 1080p and 1440p, no such caution applies — the frame rates at even the Ultra preset are generously above the bar.

Best Settings per Resolution

• 1920x1080: Ultra, averaging 191.4 FPS. The most demanding preset still delivers well over three times the playable threshold.
• 2560x1440: Ultra, averaging 119.4 FPS. Nearly double the threshold at the game's highest preset.
• 3840x2160: Ultra, averaging 67.1 FPS. Technically the best setting that stays at or above 60 FPS, though High at 80.7 FPS offers a wider margin for players sensitive to frame drops.
