Doom

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 3080 combination delivers a decisive performance statement in Doom, with measured frame rates that consistently exceed the 60 FPS playability threshold across every tested resolution and settings preset. The data shows a system that is not merely adequate but overwhelmingly capable, with the lowest recorded average being 64.7 FPS at 4K Ultra settings.

Similar Performance Alternatives

The CPU and GPU each have nearby hardware that would produce broadly similar behavior in this system. For the processor, the AMD Ryzen 5 8400F sits in a tight cluster of rivals within a fraction of a percent of its average benchmark score of 25005. The AMD Ryzen 5 7500F is essentially a statistical twin, with an average score of 24964, a negligible 0.2% difference. The Intel Core i7-11850H trails by only 0.3% with a score of 24935, while the Intel Core i7-13620H is 0.4% behind at 24911. On the other side, the AMD EPYC 9474F scores 25103, which is 0.4% higher. These deltaPct values are so small that in gaming workloads, particularly a fast-paced title like Doom, the practical performance difference would be imperceptible. The Ryzen 5 8400F’s 77th percentile ranking among all CPUs reinforces that this is a solidly mid-to-upper tier processor, but the rivals show that swapping in any of these near-identical chips would not change the gaming experience.

On the graphics side, the RTX 3080’s nearest rivals present a more curious picture. Its average benchmark score is 23172, and the closest competitors include the NVIDIA P106-100 at 23249 (-0.3%), the AMD Radeon Pro Vega 16 at 23250 (-0.3%), the AMD Radeon RX 6600M at 23273 (-0.4%), and the AMD Radeon R9 M290X at 23276 (-0.4%). These deltaPct values are again minimal, but the nature of these rivals is telling: the RTX 3080 is being compared to a mix of older workstation and mobile parts. This suggests that in pure synthetic benchmark averages, the RTX 3080’s massive 29.77 TFLOPS FP32 compute and 760.3 GB/s memory bandwidth do not translate into an overwhelmingly dominant position relative to these specific alternatives. However, the GPU’s 68th percentile ranking among all GPUs and its 10 GB of GDDR6X memory indicate that for Doom, the actual frame rates are what matter, and those are exceptional. A user moving from any of these rival GPUs to the RTX 3080 would likely see similar or better results, but the data shows the RTX 3080 is not in a class by itself based on average scores alone.

CPU and GPU Roles

The division of labor between the Ryzen 5 8400F and the RTX 3080 becomes clear when examining frame rate scaling across resolutions. At 1920x1080, the CPU has more headroom to feed the GPU, and the data shows enormous frame rates: 298.6 FPS on Low settings. This is a scenario where the GPU is likely the primary limiter, but the CPU’s 6 cores and 12 threads based on Zen 4 architecture are clearly sufficient to avoid bottlenecking. Moving to 2560x1440, the frame rates drop by a predictable margin—195.5 FPS on Low, which is a 34.5% reduction from 1080p. At 3840x2160, the Low setting yields 107.4 FPS, a further 45.1% drop from 1440p. This scaling pattern is the signature of a GPU-bound workload at higher resolutions, where the RTX 3080’s rendering load increases with pixel count, while the CPU’s role in physics, game logic, and draw call submission becomes relatively less significant.

The preset scaling within each resolution further illuminates the CPU and GPU roles. At 4K, moving from Low (107.4 FPS) to Ultra (64.7 FPS) represents a 39.8% performance penalty, which is entirely attributable to increased GPU workload from higher-quality textures, lighting, and post-processing effects. The CPU’s performance is essentially constant regardless of these visual settings, so the entire delta is borne by the GPU. At 1080p, the same Low-to-Ultra transition drops from 298.6 FPS to 180.1 FPS, a 39.7% reduction, which is remarkably consistent with the 4K scaling. This consistency suggests that even at 1080p, where the CPU could theoretically become a bottleneck at such high frame rates, the Ryzen 5 8400F’s single-thread performance (a 3dmark_single_thread score of 951 and a cinebench_r23_singlecore score of 2943) is strong enough to keep pace. The data implies that the RTX 3080 is the dominant factor in determining final frame rates across all settings, while the CPU provides a stable foundation that never becomes the limiting factor in this title.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all presets. The Low preset achieves an average of 298.6 FPS, which is nearly five times the 60 FPS playability threshold. Medium settings produce 259.5 FPS, a 13.1% reduction from Low, while High settings yield 223.5 FPS, a further 13.9% drop. The most demanding Ultra preset still maintains an average of 180.1 FPS, which is three times the playable threshold. The scaling from Low to Ultra represents a total performance cost of 39.7%, but even the worst-case scenario leaves massive headroom for high-refresh-rate monitors.

Moving to 2560x1440, the frame rates remain exceptionally high. Low settings deliver 195.5 FPS, Medium produces 170.3 FPS (a 12.9% drop from Low), High achieves 142.6 FPS (a 16.3% drop from Medium), and Ultra maintains 116.3 FPS (an 18.4% drop from High). The cumulative effect from Low to Ultra is a 40.5% reduction, closely mirroring the 1080p scaling. At this resolution, the RTX 3080’s 10 GB of GDDR6X memory and 320-bit bus are more than sufficient, and the system never dips below 116 FPS, ensuring smooth gameplay on high-refresh 1440p displays.

At 3840x2160, the system still delivers playable frame rates at every preset, but the margins tighten considerably. Low settings achieve 107.4 FPS, Medium drops to 94.6 FPS (an 11.9% reduction), High produces 79 FPS (a 16.5% reduction), and Ultra falls to 64.7 FPS (an 18.1% reduction). The Low-to-Ultra penalty is 39.8%, consistent with the other resolutions. The Ultra preset at 64.7 FPS is just 7.8% above the 60 FPS threshold, meaning that while it is playable, there is limited headroom for demanding scenes that might cause temporary dips. The min and max FPS values are not provided in the data, so the analysis relies solely on average frame rates, but the consistency of the scaling pattern suggests stable performance.

How This Combo Ranks

The combination of the Ryzen 5 8400F and RTX 3080 ranks 1047 out of 3712 tested combos in Doom. This places it in the 71.8th percentile of all tested systems, meaning it outperforms roughly 72% of all combinations in the benchmark database. This ranking is notable because the individual components have lower percentile rankings—the CPU at 77th percentile and the GPU at 68th percentile—yet their combined performance in Doom is strong enough to place the system in the upper third of all tested configurations. The data suggests that Doom is particularly well-optimized for this hardware pairing, as the game’s id Tech engine appears to scale efficiently with the CPU’s Zen 4 architecture and the GPU’s Ampere compute capabilities.

The rank of 1047 also implies that there are 2665 combos that rank lower, including many that may feature newer or more expensive components. This confirms the balance of this pairing: the Ryzen 5 8400F’s 16 MB of shared L3 cache and the RTX 3080’s 68 RT cores and 272 tensor cores work in concert to deliver frame rates that exceed what either component could achieve alone. The 4 nm CPU process node and 8 nm GPU process node represent different generations of manufacturing, but the data shows they complement each other effectively in this specific game.

The Verdict

The verdict by resolution is unambiguous: this PC can run Doom with playable performance at every resolution and every settings preset tested. At 3840x2160, all four presets—Low, Medium, High, and Ultra—are listed as playable, with the best settings being Ultra at an average of 64.7 FPS. At 2560x1440, all presets are playable, with Ultra achieving 116.3 FPS. At 1920x1080, all presets are playable, with Ultra reaching 180.1 FPS. The playable threshold is defined as 60 FPS, and the system clears this mark at every data point, with the smallest margin being the 4K Ultra result.

The implications are clear: a user with a 60 Hz 4K display can run the game at maximum visual quality, while a user with a 144 Hz 1440p monitor can also run at Ultra settings with 116.3 FPS, leaving headroom for consistent high-refresh gameplay. At 1080p, the system is capable of driving 240 Hz displays at High settings (223.5 FPS) and even approaching 300 FPS on Low settings (298.6 FPS), which is essential for competitive play. The data shows no scenario where this system fails to meet the playability standard, making it a versatile choice for Doom across a wide range of display configurations.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 64.7 FPS. This is the recommended setting for maximum visual fidelity at 4K, though the margin above the threshold is slim. For users who prioritize frame rate stability over absolute visual quality, High at 79 FPS offers a more comfortable buffer while still delivering excellent graphics.

At 2560x1440, the best settings are also Ultra, achieving 116.3 FPS. This provides a nearly 2x margin above the playability threshold, making it ideal for 144 Hz monitors. The performance headroom is substantial, and even the most demanding settings leave room for dips without dropping below 60 FPS.

At 1920x1080, Ultra is again the best setting, with an average of 180.1 FPS. This is more than three times the playable threshold, enabling high-refresh-rate gaming on 165 Hz or 240 Hz displays without compromise. The data indicates that the system is so powerful at 1080p that the choice of settings is purely a matter of visual preference, as even the heaviest preset delivers performance far beyond what is required for smooth gameplay.
