Downfall

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 3080 combination delivers a robust performance profile for Downfall, a 2016 horror title that proves surprisingly demanding at its highest settings. The measured data shows a system that is largely overqualified for standard gaming resolutions, yet encounters a significant bottleneck at 4K Ultra. This analysis breaks down the exact frame rates, component roles, and optimal configurations based solely on the benchmark results.

Measured FPS Breakdown

The benchmark data provides average FPS figures across three resolutions and four quality presets, with no minimum or maximum frame rate data recorded. At 1920x1080, the combo delivers exceptional headroom: Low settings hit 297.7 FPS, Medium achieves 243.2 FPS, High reaches 202.4 FPS, and even the most demanding Ultra preset maintains a strong 128.3 FPS. These numbers indicate that at 1080p, the system is never remotely challenged, with the gap between Low and Ultra representing a 169.4 FPS spread.

Moving to 2560x1440, performance remains highly playable but shows expected scaling pressure. Low settings produce 215.5 FPS, Medium 175.5 FPS, and High 142.2 FPS. The notable outlier is Ultra, which drops to 90.5 FPS — a 51.7 FPS reduction from High. This suggests that the Ultra preset introduces rendering features that disproportionately tax the GPU at this resolution, though the result still comfortably exceeds the 60 FPS playability threshold.

At 3840x2160, the data reveals a clear breaking point. Low settings deliver 131.2 FPS, Medium 110.4 FPS, and High 86.9 FPS — all very playable. However, Ultra plunges to 55.6 FPS, falling below the 60 FPS playability threshold. This is the only configuration in the entire dataset that fails to maintain playable performance. The transition from High to Ultra at 4K represents a 31.3 FPS drop, whereas the same preset change at 1440p only costs 51.7 FPS from an already high baseline, and at 1080p it costs 74.1 FPS. The 4K Ultra result indicates a hard performance wall where the GPU's memory bandwidth or compute resources become saturated.

CPU and GPU Roles

The scaling patterns across resolutions and presets reveal a system that is primarily GPU-limited in most scenarios, with CPU headroom to spare. The AMD Ryzen 5 8400F, with its 6 cores and 12 threads based on Zen 4 architecture, posts a Cinebench R23 multicore score of 20851 and a single-core score of 2943. This places it in the 77th percentile of all CPUs, indicating strong processing capability for a 2024 release. The RTX 3080, meanwhile, sits in the 68th percentile of all GPUs with an average benchmark score of 23172.

The resolution scaling tells a clear story. Between 1080p and 1440p, the FPS drops are relatively modest for each preset: Low goes from 297.7 to 215.5 (a 27.6% reduction), Medium from 243.2 to 175.5 (27.8%), High from 202.4 to 142.2 (29.7%), and Ultra from 128.3 to 90.5 (29.5%). This consistent ~28-30% reduction across all presets strongly implies GPU-bound behavior — the rendering load increases proportionally with pixel count, and the GPU is the limiting factor.

The transition from 1440p to 4K shows a different pattern. Low drops from 215.5 to 131.2 (39.1% reduction), Medium from 175.5 to 110.4 (37.1%), and High from 142.2 to 86.9 (38.9%). These larger percentage drops at 4K suggest the GPU is hitting memory bandwidth limits — the RTX 3080's 10 GB of GDDR6X memory with 760.3 GB/s bandwidth becomes a constraint at higher pixel counts. However, the Ultra preset's drop from 90.5 to 55.6 FPS (38.6%) follows a similar pattern, indicating the same GPU limitation rather than a sudden CPU bottleneck.

At 1080p, the CPU's 77th percentile ranking relative to all CPUs means it can likely feed the GPU adequately; the enormous frame rates (297.7 FPS at Low) suggest the CPU is not the limiting factor. The GPU's 68th percentile ranking, combined with the consistent resolution scaling, confirms that the RTX 3080 is the primary performance arbiter throughout this dataset.

Best Settings per Resolution

The optimal configuration for each resolution is the most demanding preset that maintains an average of at least 60 FPS. At 1920x1080, the best settings are Ultra, delivering 128.3 FPS — a figure nearly double the playability threshold, indicating that users could theoretically enable even more demanding graphical options if they existed, or enjoy significant headroom for future content.

At 2560x1440, the best settings are also Ultra, with an average of 90.5 FPS. This provides a comfortable 30.5 FPS margin above the 60 FPS threshold, allowing for smooth gameplay even during intense horror sequences that might cause frame-time spikes. The data shows no min or max FPS values, so the consistency of this 90.5 FPS average cannot be fully assessed, but the margin is substantial.

At 3840x2160, the best settings are High, with an average of 86.9 FPS. This is a significant step down from Ultra, which fails at 55.6 FPS. The 31.3 FPS difference between High and Ultra at 4K suggests that Ultra enables effects like volumetric lighting or advanced shadows that are disproportionately expensive at this resolution. Users prioritizing visual fidelity over frame rate might accept the sub-60 FPS Ultra experience, but the data clearly identifies High as the optimal balance for playable performance.

Similar Performance Alternatives

The nearestRivals data provides context for both components. The AMD Ryzen 5 8400F has an average benchmark score of 25005, with the closest competitor being the AMD Ryzen 5 7500F at 24964 (just 0.2% slower). The Intel Core i7-11850H scores 24935 (0.3% slower), the Intel Core i7-13620H scores 24911 (0.4% slower), and the AMD EPYC 9474F scores 25103 (0.4% faster). These deltas are negligible in real-world gaming, meaning any of these CPUs paired with the RTX 3080 would produce virtually identical frame rates in Downfall, as the game is not CPU-bound at the tested resolutions.

For the NVIDIA GeForce RTX 3080, the average benchmark score is 23172. The nearest rivals are all within 0.4% of this score: the NVIDIA P106-100 at 23249 (0.3% faster), the AMD Radeon Pro Vega 16 at 23250 (0.3% faster), the AMD Radeon RX 6600M at 23273 (0.4% faster), and the AMD Radeon R9 M290X at 23276 (0.4% faster). These GPUs would behave nearly identically in Downfall, meaning the 4K Ultra failure point at 55.6 FPS would persist, and the 1440p Ultra success at 90.5 FPS would remain achievable. The tight clustering of these benchmark scores suggests that any of these alternatives would be a drop-in replacement without meaningful performance differences.

The Verdict

This PC can absolutely run Downfall across the vast majority of configurations. At 1920x1080, every preset clears the 60 FPS threshold with ease, with Ultra achieving 128.3 FPS. At 2560x1440, all four presets are playable, with Ultra delivering 90.5 FPS. At 3840x2160, three of four presets are playable, with High providing 86.9 FPS. The only failure point in the entire dataset is 4K Ultra at 55.6 FPS, which falls 4.4 FPS short of the playability threshold. The combination of the Ryzen 5 8400F's 77th percentile CPU ranking and the RTX 3080's 68th percentile GPU ranking creates a system that excels at standard gaming resolutions but shows clear GPU limitations at the absolute highest settings.

How This Combo Ranks

The Ryzen 5 8400F + RTX 3080 combination ranks 1055th out of 3716 tested combos in Downfall. This places it in the top 28.4% of all configurations, which is a strong result given that the dataset includes far more powerful and expensive hardware. The ranking reflects the system's ability to maintain high frame rates at 1080p and 1440p, while the 4K Ultra failure prevents a higher placement. Given that the GPU sits in the 68th percentile and the CPU in the 77th percentile, the combo rank of 1055 suggests that the system performs slightly better than the average of its components' individual rankings would imply — likely because Downfall is more GPU-intensive, and the RTX 3080's strengths align well with the game's rendering demands.
