Doom

This pairing looks lopsided on paper: an end-of-life, six-core Rocket Lake chip feeding a flagship Blackwell GPU. Yet the recorded data for Doom (2016) shows the combination clearing every settings tier at every tested resolution, including 4K Ultra at an average of 102 FPS. The interesting question is not whether this PC runs the game, but where the CPU stops mattering and how much headroom is left unrealized.

FAQ

Q: Can the i5-11400F + RTX 5090 D run Doom at 4K?

A: Yes, comfortably. At 3840x2160 the combo averages 102 FPS on Ultra, 125 FPS on High, 148 FPS on Medium, and 170 FPS on Low. Every preset sits well above the 60 FPS playability threshold.

Q: What is the fastest result recorded for this combo in Doom?

A: 1080p Low, at an average of 312 FPS. The Medium run at that resolution ranged from 253 to 342 FPS at its extremes, indicating the frame ceiling is even higher than the averages suggest.

Q: Does the CPU bottleneck this game?

A: The data implies some CPU ceiling at lower resolutions. Frame rates barely move from 1440p to 1080p (189 versus 261 FPS on Ultra is the widest gap, but High goes 231 to 280 and Low goes 270 to 312). That flattening suggests the i5-11400F limits how fast frames can be fed, not the RTX 5090 D.

Q: What settings should I use at 1440p?

A: Ultra, without hesitation. It averages 189 FPS, more than three times the 60 FPS threshold, so there is no reason to drop presets at 2560x1440.

Q: How does this combo rank against other tested pairings in Doom?

A: Rank 195 out of 3712 combinations, placing it in roughly the top five percent of tested setups for this game.

Q: What hardware behaves similarly?

A: On the GPU side, the database shows the AMD Radeon RX 6650M XT (within about one percent), the RX 6850M XT, and the Tesla P100 PCIe variants as nearest rivals. On the CPU side, the i5-12450H, Ryzen 3 PRO 8300G, Core Ultra 7 164U, and even the EPYC 7H12 land within a fraction of a percent of the i5-11400F's average score.

CPU and GPU Roles

Doom is a fast-paced FPS, and this dataset tells a clear story about which component governs performance at each resolution. The RTX 5090 D, sitting in the 92nd percentile of all GPUs in the database, is massively overqualified for a 2016 title. The i5-11400F, at the 71st percentile of all CPUs, is the plausibly limiting factor.

Look at the scaling from 4K down to 1080p on each preset. On Ultra, averages go 102, 189, 261 FPS. That is a strong GPU-driven climb: cutting the pixel count nearly quadruples headroom relative to the 4K baseline, which is what you expect when the graphics card is doing the heavy lifting. But compare 1440p to 1080p. High rises only from 231 to 280, and Low from 270 to 312. Those are shallow steps for a halving of pixel count. When resolution stops buying frames, the CPU has become the governor.

The interpretation is straightforward. At 4K, the GPU dominates and the CPU is nearly irrelevant. At 1440p, both matter, and by 1080p the i5-11400F is the ceiling. The 4K Medium data reinforces this: a minimum of 126 FPS and a maximum of 170 FPS at the most demanding resolution means the worst recorded moments still doubled the playability threshold. A six-core, twelve-thread Rocket Lake part with a single-thread Passmark score of 2981 and a Cinebench R23 single-core score of 2024 can feed this engine well, but not infinitely.

One curiosity worth flagging: the RTX 5090 D's Passmark DirectX 9 score (434) is actually higher than its DirectX 11 (371) and DirectX 12 (219) scores in the database. Doom uses Vulkan, and the card's Geekbench Vulkan result of 376915 far exceeds its OpenCL result of 310674, so the API fit here is excellent. The measured frame rates support that.

Best Settings per Resolution

• 1920x1080: Ultra, averaging 261 FPS. A 70 percent margin over even the 1080p Low result of many weaker systems, and more than four times the 60 FPS threshold.
• 2560x1440: Ultra, averaging 189 FPS. High would add frames (231 FPS), but Ultra already clears the threshold by more than threefold, so there is no practical reason to compromise.
• 3840x2160: Ultra, averaging 102 FPS. Even the most demanding preset stays 42 FPS above the threshold at native 4K.

In short, the answer is Ultra at all three resolutions. The verdict data confirms this explicitly: bestSettings is Ultra at 1080p, 1440p, and 4K, with avgFpsAtBest values of 261, 189, and 102 respectively.

The Verdict

Yes, unambiguously. Every preset at every tested resolution clears 60 FPS. At 4K, all four settings tiers are playable and Ultra is the best choice at 102 FPS average. At 1440p, the same holds with Ultra at 189 FPS. At 1080p, Ultra reaches 261 FPS. There is no configuration in this dataset where the combo falls below the playability line.

The more nuanced verdict concerns what is wasted. A GPU with 21760 shading units, 104.8 TFLOPS of FP32 throughput, and 1.79 TB/s of memory bandwidth is rendering a game from 2016 at 1080p frame rates that the CPU caps before the card breaks a sweat. For Doom specifically, that waste costs nothing. For anyone choosing hardware, the data raises a fair question: would a stronger processor lift the 1080p numbers further? The flattening between 1440p and 1080p suggests it would.

Measured FPS Breakdown

All figures below are database measurements for this exact pairing.

3840x2160 (4K UHD)

| Settings | Avg FPS | Min FPS | Max FPS |

|---|---|---|---|

| Low | 170 | not recorded | not recorded |

| Medium | 148 | 126 | 170 |

| High | 125 | not recorded | not recorded |

| Ultra | 102 | not recorded | not recorded |

Note the tight spread on 4K Medium: a minimum of 126 against an average of 148, meaning frame delivery is consistent, with the floor still more than double the threshold.

2560x1440 (QHD)

| Settings | Avg FPS | Min FPS | Max FPS |

|---|---|---|---|

| Low | 270 | not recorded | not recorded |

| Medium | 257 | 219 | 296 |

| High | 231 | not recorded | not recorded |

| Ultra | 189 | not recorded | not recorded |

The Medium minimum of 219 FPS is remarkable for a 2016 title at 1440p. Even the Ultra average of 189 sits above most of the 4K results.

1920x1080 (Full HD)

| Settings | Avg FPS | Min FPS | Max FPS |

|---|---|---|---|

| Low | 312 | not recorded | not recorded |

| Medium | 297 | 253 | 342 |

| High | 280 | not recorded | not recorded |

| Ultra | 261 | not recorded | not recorded |

The 1080p Medium run peaked at 342 FPS. Yet Low only manages 312 on average, a gap of roughly five percent from Medium's average. That near-convergence across presets at 1080p is the clearest fingerprint of a CPU limit in the entire dataset: settings changes barely move the needle because the processor, not the GPU, sets the pace.

How This Combo Ranks

Against the full field of combinations tested in Doom, this pairing ranks 195 out of 3712. That places it in approximately the top five percent, an excellent standing driven overwhelmingly by the GPU. The RTX 5090 D's average benchmark score of 77712 dwarfs the i5-11400F's 17177, and the rank reflects that asymmetry: the card compensates for a modest processor in a game that is light on CPU demand.

The percentile split tells the underlying story. The GPU sits at the 92nd percentile of all GPUs; the CPU at the 71st percentile of all CPUs. Both are above average, but the gap between them is the defining characteristic of this build. In a CPU-heavier title, that gap could drag the rank down. In Doom, it does not.

Similar Performance Alternatives

For the GPU, the database's nearest rivals for the RTX 5090 D are the AMD Radeon RX 6650M XT (average score 76904, about 1.1 percent behind), the AMD Radeon RX 6850M XT (78940, 1.6 percent ahead), the NVIDIA Tesla P100 PCIe 12 GB (79396, 2.1 percent ahead), and the Tesla P100 PCIe 16 GB (79605, 2.4 percent ahead). Since these are aggregate scores rather than Doom-specific runs, a system built around any of them would be expected to land in the same general performance neighborhood, though per-game results can diverge from averages.

For the CPU, the rivals cluster extremely tightly around the i5-11400F's average score of 17177: the AMD EPYC 7H12 at 17120 (0.3 percent behind), the Intel Core i5-12450H at 17239 (0.4 percent ahead), the AMD Ryzen 3 PRO 8300G at 17278 (0.6 percent ahead), and the Intel Core Ultra 7 164U at 17074 (0.6 percent behind). Any of these processors, paired with comparable graphics, would produce a Doom experience within a rounding error of what the measured data shows here.

The takeaway from those clusters is worth stating plainly: swapping either component for its nearest rival changes almost nothing in this game. If the 1080p numbers feel constrained, the path to more frames is not a lateral CPU move, since the rivals are statistically identical, but a step up the CPU ladder entirely. Whether that step is worthwhile depends on how much the 342 FPS peak matters, and for a 2016 release, the data suggests it rarely does.
