Downfall

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 4080 delivers an exceptionally strong performance profile in Downfall, with benchmark results showing that every tested resolution and preset combination stays far above the 60 FPS playability threshold. The data indicates this combo is capable of running the game at maximum visual quality across all standard resolutions, with the most demanding Ultra preset producing 74 FPS at 4K, 120 FPS at 1440p, and 168 FPS at 1080p. This combination ranks 230th out of 3,716 tested configurations, placing it in the top 6.2% of all systems benchmarked for this title.

Measured FPS Breakdown

The measured frame rate data for this combo reveals a clear scaling pattern across resolutions and settings. At 1920x1080, the lowest resolution tested, the system produces exceptional frame rates that range from 168 FPS at Ultra settings to 400 FPS at Low settings. The Medium preset delivers 327 FPS average with a minimum of 278 FPS and a maximum of 376 FPS, while High settings achieve 268 FPS. These figures demonstrate that at 1080p, the RTX 4080 is operating far below its maximum capability, with even the most demanding preset leaving substantial performance headroom.

Moving to 2560x1440, the frame rates remain extraordinarily high but show the expected reduction from the increased pixel count. The Ultra preset delivers 120 FPS average, which represents a 28.6% decrease from the 1080p Ultra result. High settings produce 191 FPS, while Medium achieves 233 FPS with a minimum of 198 FPS and a maximum of 268 FPS. The Low preset reaches 285 FPS, indicating that even at 1440p, this combination never approaches any performance ceiling that would compromise smooth gameplay.

At 3840x2160, the system still maintains very high frame rates across all presets. The Ultra setting averages 74 FPS, which is above the 60 FPS playability threshold but represents a significant 38.3% drop from the 1440p Ultra result. High settings deliver 119 FPS, Medium achieves 145 FPS with a minimum of 123 FPS and a maximum of 167 FPS, and Low settings reach 178 FPS. The 4K results show that this is the first resolution where the combination begins to encounter meaningful load, though even the most demanding settings remain comfortably playable.

The frame time consistency, visible through the min/max data points available for Medium presets, shows tight distribution at all resolutions. At 1080p Medium, the spread between minimum and maximum is 98 FPS, while at 1440p Medium it narrows to 70 FPS, and at 4K Medium it becomes 44 FPS. This pattern suggests that as resolution increases, the frame rate becomes more consistent relative to its average, likely due to the GPU becoming the primary bottleneck and smoothing out CPU-side frame time variations.

CPU and GPU Roles

The performance scaling across resolutions reveals a clear division of labor between the Ryzen 5 8400F and the RTX 4080. At 1080p, the system achieves frame rates between 168 and 400 FPS depending on settings, which indicates that the CPU is playing a significant role in determining performance. The 400 FPS Low preset result and the 268 FPS High preset result suggest that the Ryzen 5 8400F's six cores and twelve threads are capable of feeding the GPU at very high rates, but the frame rate differences between presets at this resolution are more attributable to GPU workload than CPU limitations.

The transition from 1080p to 1440p shows a performance drop of roughly 28-29% across all presets, which is consistent with the increase in pixel count from approximately 2.07 million to 3.69 million pixels. This scaling indicates that the GPU becomes progressively more dominant as resolution increases. At 1440p, the Ultra preset's 120 FPS result versus the 1080p Ultra's 168 FPS shows that the RTX 4080 is now the primary performance determinant, with the CPU still providing adequate headroom.

The jump from 1440p to 4K produces a more dramatic performance reduction, with Ultra settings dropping from 120 FPS to 74 FPS, a 38.3% decrease. This scaling pattern strongly indicates that at 4K, the RTX 4080's rendering workload dominates the performance equation. The CPU's role diminishes further at this resolution, as evidenced by the relatively smaller performance gaps between presets at 4K compared to lower resolutions. The 119 FPS High and 145 FPS Medium results at 4K, versus 191 FPS and 233 FPS at 1440p, show that the GPU is now the limiting factor, and the Ryzen 5 8400F's processing power is sufficient to avoid becoming a bottleneck at any tested configuration.

Best Settings per Resolution

At 1920x1080, the Ultra preset delivers 168 FPS average, making it the clear choice for maximum visual quality. This result is more than double the 60 FPS playability threshold, providing substantial headroom for demanding scenes or future content updates. The 168 FPS figure indicates that even at the highest settings, this resolution is far from taxing the hardware.

For 2560x1440, the Ultra preset achieves 120 FPS average, which is again double the playability threshold. This setting provides the best visual experience while maintaining frame rates that are smooth on high-refresh-rate displays. The 120 FPS result shows that 1440p Ultra is a comfortable operating point for this combination, with no need to compromise on quality settings.

At 3840x2160, the Ultra preset maintains 74 FPS average, which exceeds the 60 FPS threshold by 23.3%. This is the most demanding configuration tested, and the result confirms that the system can handle maximum settings at 4K while remaining playable. The 74 FPS figure provides enough margin for scene complexity variations, though users seeking consistently higher frame rates at 4K might prefer the High preset at 119 FPS, which offers nearly 60% more performance.

Similar Performance Alternatives

The Ryzen 5 8400F's nearest performance rivals, based on average benchmark scores, include the AMD Ryzen 5 7500F with a score of 24,964 and a 0.2% delta, the Intel Core i7-11850H at 24,935 with a 0.3% delta, the Intel Core i7-13620H at 24,911 with a 0.4% delta, and the AMD EPYC 9474F at 25,103 with a -0.4% delta. These processors would produce very similar CPU-side performance in Downfall, meaning that systems built with any of these CPUs paired with an RTX 4080 would deliver nearly identical frame rates, particularly at 1440p and 4K where GPU load dominates.

On the GPU side, the RTX 4080's nearest rivals include the NVIDIA GeForce RTX 4080 SUPER with a score of 54,209 and a 0.1% delta, the AMD Radeon Pro W5700X at 54,828 with a -1.1% delta, the AMD Radeon RX 6750 GRE 12 GB at 55,698 with a -2.6% delta, and the AMD Radeon 8060S at 55,757 with a -2.7% delta. The RTX 4080 SUPER, being essentially identical in performance, would deliver the same gaming experience. The AMD options, despite their slightly higher average benchmark scores, would produce comparable frame rates in Downfall, though the delta percentages suggest the differences are minimal and unlikely to be perceptible in real-world gameplay.

A system using the Ryzen 5 8400F with an RTX 4080 SUPER would behave almost identically to this tested configuration, as would a build pairing the Ryzen 5 7500F with the RTX 4080. The Intel alternatives, while matching CPU performance, would require different motherboards and potentially different memory support, but the gaming outcome in Downfall would be effectively the same given the GPU-dominant nature of the workload at higher resolutions.

How This Combo Ranks

This combination ranks 230th out of 3,716 tested configurations in Downfall, placing it in the top 6.2% of all systems benchmarked for this game. This ranking reflects the strong synergy between the Ryzen 5 8400F and RTX 4080, with the CPU providing sufficient single-thread performance for the game's logic while the GPU delivers exceptional rasterization throughput. The percentile placement indicates that this combo outperforms 93.8% of tested systems, making it a high-end configuration capable of delivering maximum settings at all resolutions.

The ranking becomes more meaningful when considering the game's horror genre and its release date of 2016-02-28. Downfall is not an exceptionally demanding title by modern standards, which explains why this combo achieves such high frame rates across all settings. The 4K Ultra result of 74 FPS, while above the playability threshold, represents the closest this combination comes to being challenged, suggesting that more demanding modern titles would push this hardware harder.
