Doom

FAQ

Q: Can this PC run Doom at 4K resolution?

A: Yes. The recorded data shows all four settings presets (Low, Medium, High, Ultra) clear the 60 FPS playable threshold at 3840x2160. The most demanding preset, Ultra, still averages 92.3 FPS.

Q: What is the best settings preset for 1440p gaming?

A: Ultra is the best choice at 2560x1440, averaging 197.2 FPS on High and 166.7 FPS on Ultra. Since every preset exceeds 60 FPS, the database recommends Ultra for maximum visual quality.

Q: How does the Intel Core i5-9400 compare to its nearest rivals?

A: The i5-9400 sits at the 47th percentile among all CPUs. Its average benchmark score of 2254 is nearly identical to the Intel Core i7-1068NG7 (2259, 0.2% slower) and the Intel Core i3-10305 (2264, 0.4% slower). It edges out the AMD Ryzen 5 PRO 1500 by 0.4%.

Q: Is the RTX 5080 a high-performing GPU in the database?

A: Yes. The RTX 5080 ranks in the 87th percentile among all GPUs, with an average benchmark score of 56083. It leads the AMD Radeon 8060S by 0.6% and trails the AMD Radeon RX 9070 GRE by 2.2%.

Q: What frame rates can be expected at 1080p on Ultra settings?

A: The measured average is 214.6 FPS at 1920x1080 with Ultra settings. Even the most demanding preset leaves substantial headroom above the 60 FPS threshold.

Q: Does the CPU bottleneck the GPU in this game?

A: The data does not indicate a bottleneck. At 1080p Low, the combo reaches 251.5 FPS, and scaling from Low to Ultra at every resolution shows consistent GPU-driven performance drops. The i5-9400's six cores and six threads appear sufficient for this title.

CPU and GPU Roles

The recorded FPS data reveals a clear pattern: the NVIDIA GeForce RTX 5080 is the dominant performance driver in Doom, while the Intel Core i5-9400 provides adequate support without becoming a limiting factor.

At 1920x1080, the difference between Low and Ultra settings is 36.9 FPS (251.5 down to 214.6). This 14.7% penalty for maximum visual quality reflects GPU workload scaling. The CPU's role is largely static across presets, as the i5-9400's six threads handle the game's simulation and draw call overhead comfortably.

Moving to 2560x1440, the GPU's influence grows. Low settings average 220.4 FPS, while Ultra drops to 166.7 FPS, a 53.7 FPS gap. The resolution increase from 1080p to 1440p costs 31.1 FPS on Low and 47.9 FPS on Ultra. This widening delta indicates that pixel throughput, not CPU processing, is the primary constraint.

At 3840x2160, the GPU workload dominates entirely. Low averages 150.2 FPS, Medium 128.1, High 109.7, and Ultra 92.3. The spread from Low to Ultra is 57.9 FPS, the largest of any resolution. Compared to 1080p, 4K costs 101.3 FPS on Low and 122.3 FPS on Ultra. These figures confirm that Doom scales almost exclusively with GPU rendering load across resolutions.

The i5-9400's benchmark profile supports this interpretation. Its Cinebench R23 multicore score of 6629 and single-core score of 935 place it in the 47th CPU percentile, a mid-range position. Yet the combo still achieves over 90 FPS at 4K Ultra. Even the most demanding scenario in the dataset leaves the CPU with headroom. The RTX 5080's 56.28 TFLOPS FP32 performance and 960.0 GB/s memory bandwidth are the clear throughput drivers.

In practical terms, users upgrading from a weaker GPU should expect large FPS gains at every resolution. Users upgrading the CPU alone would see minimal improvement in this title, as the recorded measurements show no CPU-bound frame rate ceiling.

How This Combo Ranks

The Intel Core i5-9400 and NVIDIA GeForce RTX 5080 combination ranks 651st out of 3712 tested combos in Doom. This places the pairing in the top 17.5% of all configurations in the database.

The rank reflects a notable asymmetry. The GPU alone sits at the 87th percentile among all GPUs, while the CPU rests at the 47th percentile. The combined result, 651st of 3712, is pulled downward by the aging six-core processor. Yet the gap between the GPU's percentile and the combo's rank is modest, indicating that Doom's engine does not heavily penalize the i5-9400's older Coffee Lake architecture.

The RTX 5080's nearest rivals in the database include the AMD Radeon 8060S (0.6% slower), AMD Radeon RX 6750 GRE 12 GB (0.7% slower), and AMD Radeon Pro W5700X (2.3% slower). The AMD Radeon RX 9070 GRE is 2.2% faster. These small deltas suggest that the 5080's raw score is tightly clustered with upper-midrange competitors. The combo's actual in-game performance, however, benefits from the 5080's 16 GB GDDR7 memory running at 960.0 GB/s, factor that pushes beyond the raw average score.

Within the 3712-combo pool, the 651st rank translates to a configuration that outputs 3.5x the playable threshold at 4K Ultra (92.3 FPS average versus 60.0 threshold). At 1080p Ultra, the 214.6 FPS average is 3.6x the threshold. The ranking data indicates that this PC will outrun the vast majority of tested systems in Doom, even with a mid-range CPU.

The i5-9400's nearest CPU rivals, such as the Intel Core i3-10305 (2264 average score, 0.4% faster) and Intel Core i7-10710U (2248 average, 0.3% slower), would not meaningfully change the combo ranking. The CPU's 0.2% to 0.4% deltas around the 2254 average score are within noise. The 5080's 2.2% gap to the RX 9070 GRE is the largest CPU comparison delta in the set, yet that GPU delta of 2.3% to the Pro W5700X still falls within the same range.

The Verdict

Yes, this PC can run Doom at every resolution and preset combination recorded in the database. The verdict by resolution confirms all three tested resolutions (1920x1080, 2560x1440, 3840x2160) list Low, Medium, High, Ultra as playable settings.

At 3840x2160, the Ultra preset is the best settings choice, averaging 92.3 FPS, well above the 60 FPS threshold. The 4K High preset averages 109.7 FPS, and Medium reaches 128.1 FPS. Low averages 150.2 FPS, meaningfully above playable.

At 2560x1440, Ultra is the best settings preset, averaging 166.7 FPS. High averages 197.2 FPS, Medium 209.9, Low 220.4. All four presets clear 60 FPS by wide margins.

At 1920x1080, Ultra averages 214.6 FPS, the lowest recorded average of the resolution. High averages 229.5, Medium averages 239.5, Low 251.5. The 1080p Low setting shows the highest single average in the entire dataset at 251.6 FPS, well above playable requirements.

The verdict is unambiguous across the board, every preset is playable. The lowest average FPS recorded in the dataset is 214.4 FPS at 1920x1080 Low, 220.2 FPS at 2560x1440 Low, 150.2 FPS at 3840x2160 Low. The playable threshold of 60 FPS is cleared at all times. The database does not record any min or max FPS values, only average FPS per resolution per settings.

The 60 FPS playable threshold is met, and the most demanding settings preset, Ultra at 3840x2160, is 92.3 FPS average, 3.5x the playable threshold.
