Downfall

How This Combo Ranks

The AMD Ryzen 5 8400F paired with the Intel Arc B390 lands near the bottom of the database for Downfall, sitting at rank 3303 out of 3716 tested combinations. This places the combo in the 11th percentile of all recorded system configurations, meaning roughly 89% of tested hardware pairs deliver higher average frame rates in this horror title. The ranking reflects a fundamental imbalance: the CPU is a mid-range desktop part with strong compute scores, while the GPU is an integrated-class solution that struggles under the game's rendering demands.

At 1080p, the combo manages to clear the 60 FPS threshold on three of four presets, which is respectable given the GPU's low standing. The recorded data shows the system reaching 106 FPS on Low, 87 FPS on Medium, and 71 FPS on High at 1920x1080. These numbers push the combo into playable territory for the majority of settings at that resolution. However, the Ultra preset collapses to 44 FPS, a drop that reveals the GPU's limits when the game's visual effects stack up.

Moving to 1440p, the picture shifts notably. The combo still achieves playable frame rates on Low (76 FPS) and Medium (62 FPS), but High falls to 51 FPS and Ultra to 32 FPS. The 4K results are uniformly below the playable threshold, with the best average being 47 FPS on Low and the worst being 20 FPS on Ultra. Across all resolutions, the pattern is consistent: the Arc B390's 9th percentile GPU ranking (relative to all GPUs in the database) directly constrains what this system can deliver, regardless of the CPU's 77th percentile standing.

What makes this ranking notable is the gap between component potential and realized performance. The CPU's average benchmark score of 25005 places it in the upper quartile of all processors, yet the GPU's average score of 1482 places it in the bottom decile. In a game like Downfall, which appears to be GPU-bound at higher settings, the CPU's headroom goes unused. The combo rank of 3303 reflects this bottleneck, and the data suggests that pairing this CPU with a more capable GPU would yield dramatically better results, though such configurations fall outside the scope of this analysis.

Similar Performance Alternatives

The nearest rivals for the AMD Ryzen 5 8400F provide context for what the CPU contributes to this pairing. The AMD Ryzen 5 7500F scores nearly identically with an average benchmark of 24964, just 0.2% behind. The Intel Core i7-11850H and Intel Core i7-13620H follow at 24935 (0.3% behind) and 24911 (0.4% behind), respectively. On the other side, the AMD EPYC 9474F scores 25103, 0.4% ahead. These deltas are so small that swapping the 8400F for any of these CPUs would produce essentially identical frame rates in Downfall, assuming the GPU remains unchanged. The CPU's role here is not the limiting factor; any of these near-equal processors would behave the same way when paired with the Arc B390.

For the GPU, the nearest rivals paint a starker picture. The Intel Arc B390 scores 1482 on the 3DMark Steel Nomad DX12 test, putting it just 1.3% ahead of the NVIDIA GeForce GT 520MX (1463), 1.5% ahead of the NVIDIA GeForce 800M (1460), 2.5% ahead of the NVIDIA GeForce GT 625 OEM (1446), and 2.7% ahead of the NVIDIA GeForce GT 710 (1443). These are all entry-level or legacy mobile/desktop parts, which explains why the combo ranks so low. Users coming from any of these GPUs would see nearly identical performance in Downfall, though the Arc B390 does edge them out by a small margin. The practical takeaway is that this GPU class sits at the very bottom of the performance spectrum, and the measured FPS figures reflect that positioning.

The similarity among CPU rivals means that the recorded frame rates for this combo would remain largely unchanged if the processor were swapped for a 7500F or a 13620H. The GPU rivals, meanwhile, would all deliver within a few percent of the same results, so the gameplay experience would feel identical. This combination of a strong CPU with a weak GPU creates a specific profile: the system is CPU-ready for demanding titles, but the GPU becomes the ceiling for any modern game, including Downfall.

Best Settings per Resolution

The database records the most demanding preset that maintains an average of at least 60 FPS at each resolution. For 3840x2160, no preset achieves this threshold. The closest is Low at 47 FPS, followed by Medium at 39 FPS, High at 32 FPS, and Ultra at 20 FPS. None of these are playable by the 60 FPS standard, so the system cannot sustain smooth gameplay at 4K under any settings.

At 2560x1440, the best playable setting is Medium, which delivers an average of 62 FPS. This just clears the 60 FPS bar, with minimum recorded at 53 FPS and maximum at 71 FPS. Low also remains playable at 76 FPS, but Medium offers a better visual balance while staying above the threshold. High and Ultra fall short at 51 FPS and 32 FPS, respectively, so they are not recommended for a consistent 60+ FPS experience.

At 1920x1080, the best playable setting is High, achieving 71 FPS on average. This is a comfortable margin above the threshold, and it represents the highest visual quality that still maintains smooth performance. Low (106 FPS) and Medium (87 FPS) also clear 60 FPS, but they offer reduced visual fidelity. Ultra drops to 44 FPS, which is not playable under the database's standard. For users prioritizing frame rate, High at 1080p is the sweet spot, balancing image quality with the 71 FPS average.

The Verdict

Can this PC run Downfall? The answer depends entirely on resolution and settings. At 1920x1080, the system is playable on High, Low, and Medium presets, with High being the best option at 71 FPS. The Ultra preset fails to reach 60 FPS, so it should be avoided if smooth gameplay is the priority. At 2560x1440, the system remains playable on Low and Medium, with Medium being the best choice at 62 FPS. High and Ultra are not viable, dropping to 51 FPS and 32 FPS respectively. At 3840x2160, no preset achieves playable frame rates; the best case is 47 FPS on Low, which falls short of the threshold.

The data clearly indicates that this combo is best suited for 1080p gaming with medium-to-high settings. Users targeting 1440p can still play, but they must accept Medium settings and the associated visual compromises. 4K is effectively out of reach for smooth gameplay. The verdict by resolution confirms this: 1080p supports High at 71 FPS, 1440p supports Medium at 62 FPS, and 4K supports no playable settings. For a horror game where atmosphere and pacing matter, the 1080p High preset at 71 FPS provides a solid experience, though users with higher-resolution displays will need to scale down or upgrade the GPU.

Measured FPS Breakdown

The measured frame rates reveal how the combo degrades as resolution and settings increase. At 1920x1080, the system delivers 106 FPS on Low, 87 FPS on Medium, and 71 FPS on High. The Medium preset shows a minimum of 74 FPS and a maximum of 100 FPS, indicating stable performance with occasional dips. Ultra drops to 44 FPS, a 58% reduction from Low, which highlights the GPU's inability to handle the highest visual effects even at 1080p.

At 2560x1440, the averages are 76 FPS on Low, 62 FPS on Medium, 51 FPS on High, and 32 FPS on Ultra. The Medium preset records a minimum of 53 FPS and a maximum of 71 FPS, showing that the 62 FPS average comes with noticeable variance, occasionally dipping below the 60 FPS threshold. High at 51 FPS is close to playable but not quite there, while Ultra is less than half of the Low average.

At 3840x2160, the results are uniformly poor: 47 FPS on Low, 39 FPS on Medium, 32 FPS on High, and 20 FPS on Ultra. The Medium preset shows a minimum of 33 FPS and a maximum of 44 FPS, meaning even the best case falls far short of smooth gameplay. The scaling from 1080p to 1440p to 4K shows a consistent penalty of roughly 30-40% at each step for the same settings, which is expected for a GPU with such limited throughput.

The minimum and maximum frame data is only recorded for Medium presets at each resolution, but that limited data still offers insight. At 1080p Medium, the spread from 74 to 100 FPS suggests the CPU can keep up, and the GPU is the limiting factor during heavier scenes. At 1440p Medium, the 53 to 71 FPS spread shows more volatility, with dips below the playable threshold. At 4K Medium, the 33 to 44 FPS range indicates consistent sub-60 performance with no relief.

CPU and GPU Roles

The data shows that the Intel Arc B390 is the dominant constraint in this pairing for Downfall. The GPU's 9th percentile ranking and its nearest rivals (all legacy or entry-level parts) make this clear. At every resolution, the frame rate drops as settings increase, which is a GPU-bound behavior. The CPU, with its 77th percentile ranking and robust multi-threaded scores (including a Cinebench R23 multi-core score of 20851), is not the bottleneck. If the CPU were the limiting factor, we would expect to see frame rates plateau across settings rather than scale down so steeply.

Comparing resolution scaling reinforces this conclusion. At 1080p High, the combo hits 71 FPS; at 1440p High, it drops to 51 FPS; at 4K High, it falls to 32 FPS. This 55% reduction from 1080p to 4K at the same settings is characteristic of a GPU that runs out of fill rate and shading power as pixel count rises. The CPU's workload for Downfall is likely modest, given the game's 2016 release and horror genre focus, so the 6-core, 12-thread Ryzen 5 8400F has ample headroom.

The preset scaling within each resolution also points to the GPU as the key factor. At 1080p, going from Low to Ultra cuts the frame rate from 106 to 44 FPS, a 58% loss. At 1440p, the same change drops from 76 to 32 FPS, a 58% loss. At 4K, Low to Ultra goes from 47 to 20 FPS, a 57% loss. These nearly identical percentages across resolutions indicate that the GPU's shader and texture units are the binding constraint, and the CPU's contribution is secondary. For users considering upgrades, the data suggests that replacing the GPU would yield far larger gains than swapping the CPU, though the database does not record such alternative configurations.
