Doom

Doom (2016) is decisively playable on this AMD Ryzen 5 8400F + NVIDIA GeForce RTX 4080 combination, and the benchmark data shows the system is so far ahead of the 60 FPS threshold that it can run the most demanding preset at every resolution. The RTX 4080's 48.74 TFLOPS FP32 compute and the Ryzen 5 8400F's 20,851 Cinebench R23 multi-core score combine to deliver average frame rates that range from 85 FPS at 4K Ultra to 241 FPS at 1080p Ultra, meaning the only limitation a user might face is display refresh rate, not hardware capability.

Best Settings per Resolution

At 3840x2160 (4K), the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 85 FPS. This is a substantial margin above the playability threshold, and the data shows that even the heaviest settings leave 25 FPS of headroom. The 4K Ultra result is notable because it is the only resolution where the Ultra preset drops below triple-digit frame rates, yet it still comfortably clears the 60 FPS bar. The measured FPS breakdown for 4K shows a clear progression: Low averages 141 FPS, Medium averages 123 FPS, High averages 104 FPS, and Ultra averages 85 FPS.

At 2560x1440 (1440p), the best settings are again Ultra, with an average of 156 FPS. This represents a 71 FPS jump over the 4K Ultra result, indicating that the resolution reduction from 2160p to 1440p relieves significant GPU pressure. The 1440p data shows Low at 260 FPS, Medium at 226 FPS, and High at 191 FPS, with Ultra at 156 FPS. Every preset at this resolution nearly triples the 60 FPS requirement, and the Ultra setting still delivers more than double the playable threshold.

At 1920x1080 (1080p), the best settings are Ultra, with an average of 241 FPS. This is the highest frame rate at any resolution for the Ultra preset, and it demonstrates that the RTX 4080 is essentially unchallenged at 1080p. The full 1080p spectrum shows Low at 386 FPS, Medium at 350 FPS, and High at 295 FPS, with Ultra at 241 FPS. The 241 FPS Ultra result is particularly impressive because it is 4x the playable threshold, and even the most conservative interpretation of the data indicates that this system is built for high-refresh-rate 1080p gaming.

CPU and GPU Roles

The benchmark data reveals a system where the GPU is the primary performance driver at 4K, but the CPU's strong single-thread performance becomes increasingly relevant at lower resolutions. The Ryzen 5 8400F's 3DMark single-thread score of 951 and Passmark single-thread score of 3685 provide the foundation for high frame rates at 1080p, where the RTX 4080's 716.8 GB/s memory bandwidth and 9728 shading units are less likely to bottleneck.

The scaling between resolutions confirms this division of labor. Moving from 4K to 1440p, the Ultra preset improves from 85 FPS to 156 FPS, an 83.5% increase. Moving from 1440p to 1080p, Ultra improves from 156 FPS to 241 FPS, a 54.5% increase. The diminishing returns as resolution drops indicate that the GPU is still the limiting factor even at 1080p, but the CPU's role grows proportionally. At 1080p Ultra, the system achieves 241 FPS, which is close to what the Ryzen 5 8400F's 3DMark max-thread score of 6165 would suggest is the CPU ceiling for this game engine.

The Low preset scaling further illustrates this dynamic. At 4K Low, the average is 141 FPS; at 1440p Low, it is 260 FPS; at 1080p Low, it is 386 FPS. The 1080p Low result is particularly telling — at 386 FPS, the system is likely hitting engine or CPU-imposed limits rather than GPU limits, since the RTX 4080's Passmark G3D score of 34457 indicates it can handle far more than 386 FPS in lighter scenes. The 65W TDP of the CPU and 320W TDP of the GPU suggest a balanced power envelope, but the performance data clearly shows that the GPU is the workhorse at 4K and the CPU becomes co-equal at 1080p.

FAQ

Q: Can this system run Doom at 4K Ultra with a 60 FPS minimum?

A: Yes. The measured average at 3840x2160 Ultra is 85 FPS, which is above the 60 FPS playable threshold. The 4K Medium preset shows a minimum of 104 FPS and maximum of 141 FPS, indicating that even the Ultra preset, which lacks explicit min/max data, leaves substantial headroom.

Q: What is the highest frame rate this system can achieve in Doom at 1080p?

A: The highest measured average is 386 FPS at 1920x1080 with Low settings. The Medium preset at 1080p shows a minimum of 297 FPS and maximum of 402 FPS, suggesting that the absolute ceiling for this combination is around 400 FPS in light scenes.

Q: How does the RTX 4080 compare to its closest rival, the RTX 4080 SUPER, for this game?

A: The RTX 4080 has an average benchmark score of 54247, while the RTX 4080 SUPER scores 54209, a delta of just 0.1%. For Doom specifically, the measured FPS data indicates the RTX 4080 is more than sufficient, and the performance difference between these two cards would be imperceptible in practice.

Q: Is the Ryzen 5 8400F a bottleneck for the RTX 4080 in this game?

A: The data suggests no significant bottleneck. At 1080p Low, the system reaches 386 FPS, which is in line with the CPU's 3DMark max-thread score of 6165. The CPU's percentile rank of 77 versus all CPUs and its average benchmark score of 25005 indicate it is a strong mid-range processor that keeps pace with the GPU at all tested resolutions.

Q: What preset should be used for a 144Hz 1440p monitor?

A: Ultra at 2560x1440 delivers 156 FPS on average, which exceeds 144Hz. Even the High preset at 191 FPS would be suitable, but Ultra is recommended because it provides the best visual quality while still clearing the 144 FPS target.

Q: Does the system maintain above 60 FPS in all settings at 4K?

A: Yes. The lowest measured average at 4K is 85 FPS on Ultra. The Low preset averages 141 FPS, Medium averages 123 FPS, and High averages 104 FPS. All four presets at 4K are above 60 FPS, and the playable settings list confirms all of them qualify.

Similar Performance Alternatives

The AMD Ryzen 5 8400F's nearest rival is the AMD Ryzen 5 7500F, with an average score of 24964 against the 8400F's 25005, a delta of just 0.2%. This means the 7500F would deliver virtually identical frame rates in Doom, making it a drop-in alternative for users who prefer that SKU. The Intel Core i7-11850H scores 24935 (0.3% delta) and the Intel Core i7-13620H scores 24911 (0.4% delta), both within a negligible performance margin. On the higher side, the AMD EPYC 9474F scores 25103 (-0.4% delta), which is technically faster but represents a server-class part that would not typically be considered for gaming.

For the GPU, the NVIDIA GeForce RTX 4080 SUPER is the closest alternative with an average score of 54209 versus the RTX 4080's 54247, a delta of 0.1%. In Doom, this translates to a difference of less than 1 FPS at any resolution, so users should not expect any measurable distinction. The AMD Radeon Pro W5700X scores 54828 (-1.1% delta), which is slightly higher on average but is a workstation card. The AMD Radeon RX 6750 GRE 12 GB scores 55698 (-2.6% delta) and the AMD Radeon 8060S scores 55757 (-2.7% delta), both of which are nominally faster in synthetic benchmarks but fall within a range that would not produce a visible difference in Doom's frame rates.

Measured FPS Breakdown

At 3840x2160, the complete FPS data is as follows: Low averages 141 FPS, Medium averages 123 FPS with a minimum of 104 FPS and maximum of 141 FPS, High averages 104 FPS, and Ultra averages 85 FPS. The Medium preset's min/max range of 104 to 141 FPS demonstrates that even at 4K, the system maintains consistent performance without severe frame-time spikes. The progression from Low to Ultra shows a 39.7% performance cost for maximum visual quality, which is a reasonable trade-off given that even the most demanding preset remains well above 60 FPS.

At 2560x1440, the data shows: Low averages 260 FPS, Medium averages 226 FPS with a minimum of 192 FPS and maximum of 260 FPS, High averages 191 FPS, and Ultra averages 156 FPS. The 1440p Medium range of 192 to 260 FPS shows a wider spread than at 4K, which is expected as the GPU has more headroom to push higher peaks. The Ultra preset at 156 FPS is particularly notable because it almost exactly matches the 1440p High preset at 4K (104 FPS) in terms of relative quality level, yet runs 50% faster due to the resolution reduction.

At 1920x1080, the complete breakdown is: Low averages 386 FPS, Medium averages 350 FPS with a minimum of 297 FPS and maximum of 402 FPS, High averages 295 FPS, and Ultra averages 241 FPS. The 1080p Medium range of 297 to 402 FPS is the widest of any resolution, which reflects the CPU beginning to assert its influence at such high frame rates. The Ultra preset's 241 FPS is 4x the playable threshold, and the Low preset's 386 FPS approaches the practical limits of the game engine's rendering loop.

The Verdict

This system can run Doom at every resolution and every preset above 60 FPS. The verdict by resolution confirms that all four settings — Low, Medium, High, and Ultra — are playable at 3840x2160, 2560x1440, and 1920x1080. The best settings at each resolution are Ultra, with average frame rates of 85 FPS at 4K, 156 FPS at 1440p, and 241 FPS at 1080p. The 4K Ultra result is the only data point that falls below 100 FPS, but it still provides 42% more performance than the 60 FPS playability threshold, meaning there is no scenario in which this hardware struggles with Doom.

The combination ranks 272nd out of 3712 tested combos in this game, placing it in the top 7.3% of all systems. The RTX 4080's percentile rank of 86 against all GPUs and the Ryzen 5 8400F's percentile rank of 77 against all CPUs indicate that this is a well-matched pair for Doom's engine, which was released in 2016 and does not heavily tax modern hardware. For users targeting high refresh rates, the 1440p Ultra result of 156 FPS supports 144Hz monitors, while the 1080p Ultra result of 241 FPS supports 240Hz displays. The only caveat is that the GPU is end-of-life per its production status, and the 16 GB GDDR6X memory and 716.8 GB/s bandwidth are more than Doom requires, but this does not affect current performance. The data is measured, not estimated, and every result indicates a system that is not merely playable but performant at the highest levels.
