Downfall

The AMD Ryzen 5 5600F paired with the AMD Radeon RX 580 in Downfall presents a system where the graphics card becomes the primary constraint as resolution climbs, while the six-core processor provides a stable foundation. The measured frame rates show a clear pattern of diminishing returns at higher resolutions, with the GPU’s 8 GB memory and 256-bit bus determining the ceiling. This analysis breaks down the performance data from the FACT PACK, focusing on how the components interact across the tested configurations.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a steep performance drop that identifies the GPU as the bottleneck. At High settings, the average frame rate falls from 68 FPS at 1080p to 49 FPS at 1440p, a 28% reduction, and then to 30 FPS at 4K, a 56% reduction from the 1080p baseline. This non-linear scaling indicates that the Radeon RX 580’s pixel throughput and memory bandwidth are being saturated as the pixel count quadruples from 1080p to 4K.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, Low yields 102 FPS while Ultra produces 43 FPS, a 59 FPS spread. At 1440p, the spread narrows to 42 FPS (73 vs 31), and at 4K it tightens to 26 FPS (45 vs 19). This compression at 4K suggests that even the lowest settings cannot escape the GPU’s raw fill-rate limitations, whereas at 1080p the processor has enough headroom to let the graphics card stretch its legs on lower presets.

The data shows that the CPU is not the limiting factor in this title. The Ryzen 5 5600F’s multi-threaded score of 19236 in PassMark and single-thread score of 2872 place it in the 85th percentile of all CPUs, which is more than sufficient for a horror game released in 2016. The real evidence lies in the scaling pattern: if the CPU were the constraint, the frame rate would plateau or drop uniformly regardless of resolution, but instead the performance scales inversely with pixel count, a classic GPU-bound signature.

At Medium settings, the only preset with min/max FPS data, the pattern holds. The 1080p result shows 83 FPS average with a 71 FPS minimum and 96 FPS maximum, while 1440p drops to 60 FPS average (51 min, 69 max), and 4K falls to 37 FPS (32 min, 43 max). The consistency of the minimum frame rates relative to averages suggests stable frame pacing, but the absolute values at 4K confirm that this resolution is only playable on Low settings.

CPU Role

The AMD Ryzen 5 5600F is a 5000-series desktop processor with 6 cores and 12 threads, based on Zen 3 architecture codenamed Vermeer. Its base clock of 3.00 GHz and boost clock of 4.00 GHz provide adequate compute for Downfall’s demands, as evidenced by the benchmark results. The PassMark multithread score of 19236 and physics score of 1043 indicate that the processor can handle game logic and physics calculations without becoming a bottleneck at any tested setting.

The CPU’s cache hierarchy, including 32 MB of shared L3 cache, helps with data locality in a horror game that likely features asset streaming and procedural elements. However, the benchmark data does not show a scenario where the CPU limits performance. Even at 1080p Low with 102 FPS average, the frame rate is still climbing, and the absence of a plateau in the resolution scaling suggests the GPU is already at its limit before the CPU can be stressed.

The nearestRivals data places the 5600F within 0.5% of processors like the Intel Core Ultra 5 225 and AMD Ryzen 5 5500X3D, with average scores of 36945 versus 36938 and 37018 respectively. This tight grouping confirms that the 5600F sits in a well-populated performance band, and in Downfall specifically, its 6-core configuration is more than enough for a title from 2016 that was designed for lower-thread-count CPUs.

The processor’s TDP of 65 W and 7 nm process node (TSMC) mean it operates efficiently, but these power characteristics do not directly translate to game performance. What matters is the 12 threads available for background tasks and the 4.00 GHz boost clock for single-threaded game logic, both of which are demonstrably sufficient given the GPU-bound frame rates observed across all settings.

GPU Role

The AMD Radeon RX 580 is the decisive component in this pairing. With 8 GB of GDDR5 memory on a 256-bit bus providing 256.0 GB/s of bandwidth, the card has enough memory capacity for 1080p and 1440p, but the 4K results show it struggling to maintain playable frame rates. The GPU’s base clock of 1257 MHz and boost clock of 1340 MHz, combined with 2304 shading units, yield a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s.

These specifications explain the measured FPS. At 4K Ultra, the average drops to 19 FPS, which is unplayable, while 4K High yields 30 FPS. The card’s 6.175 TFLOPS FP32 performance is simply insufficient for the 8.3 million pixels at 4K when rendering at high quality. The memory bandwidth of 256.0 GB/s also becomes a limiting factor, as the 4K resolution requires significantly more data per frame.

The GPU’s benchmark scores reflect its mid-range position. The PassMark G3D score of 8813 places it in the 53rd percentile of all GPUs, and its nearestRivals include the NVIDIA GeForce GTX 1660 SUPER with an average score of 12986 and the AMD Radeon 740M with 12870. The RX 580’s average benchmark score of 12928 is within 0.5% of these competitors, confirming its position as a capable 1080p card that can handle 1440p with reduced settings.

The 8 GB VRAM is not the primary constraint in Downfall, as even the 4K Low setting achieves 45 FPS, indicating the card can fit the necessary textures. Instead, the limiting factor is the GPU’s compute throughput and memory bandwidth, which drop off sharply as resolution increases. The data shows that the RX 580 is best suited for 1080p gaming, where it delivers over 60 FPS on High and Medium settings, and can manage 1440p at Low or Medium for a playable experience.

Settings Recommendations

Based on the measured FPS data, the optimal experience balances visual quality with frame rate smoothness. At 1920x1080, the Medium preset delivers 83 FPS average with a 71 FPS minimum and 96 FPS maximum, which is the sweet spot for this combination. This provides a 60+ FPS floor and headroom for demanding scenes, while High settings (68 FPS average) sacrifice 15 FPS for marginal visual gains. Ultra at 43 FPS average is below the 60 FPS threshold and should be avoided.

For 2560x1440, the Low preset yields 73 FPS average, which is the only setting that comfortably exceeds 60 FPS. Medium drops to 60 FPS average with a 51 FPS minimum, which is borderline playable but may experience stutter in intense moments. High (49 FPS) and Ultra (31 FPS) are not recommended for smooth gameplay. Given the horror genre’s reliance on atmosphere, the Low preset at 1440p is the pragmatic choice, as it maintains fluid motion.

At 3840x2160, the data suggests that only Low settings (45 FPS average) are viable, and even then, the experience is marginal. Medium (37 FPS) and High (30 FPS) are below the 60 FPS standard, and Ultra (19 FPS) is unplayable. For users insisting on 4K, the Low preset is the only option, but the measured minimums (32 FPS at Medium) indicate that frame drops will be noticeable. The recommendation is to play at 1080p Medium for the best combination of visual fidelity and performance.

The Medium preset’s min/max data across all resolutions shows consistent frame pacing, with the 1080p result (71 min, 96 max) having an 83 FPS average. This indicates that the preset is well-optimized for the hardware, providing a stable experience without the extreme frame time spikes that can occur on Ultra settings where the GPU is overworked.

How This Combo Ranks

The AMD Ryzen 5 5600F + AMD Radeon RX 580 combination ranks 3395 out of 3716 tested combos in Downfall, placing it in the bottom 9% of systems. This low ranking is primarily due to the GPU’s age and performance level, as the RX 580 is an end-of-life product from 2017. The CPU, in contrast, is a modern 2025 release with a 85th percentile ranking, but the pairing is held back by the graphics card’s 53rd percentile standing.

This ranking disparity between the components is telling. The CPU is capable of driving much faster GPUs, but the RX 580 limits the system’s overall performance. In a game like Downfall, which is not particularly demanding by modern standards, the combo still only manages to achieve playable frame rates at 1080p Medium or 1440p Low. The 3395th rank out of 3716 indicates that most other tested combinations, even those with lower-end CPUs, outperform this pairing due to superior GPU choices.

The nearestRivals for the CPU (Intel Core Ultra 5 225, AMD Ryzen 5 5500X3D) all have similar average scores, but when paired with better GPUs, they would likely rank significantly higher. The combo’s low rank is not a reflection of the CPU’s deficiencies but rather the GPU’s inability to translate the processor’s headroom into higher frame rates. In this context, the ranking serves as a warning that the RX 580 is the system’s bottleneck and should be upgraded before the CPU.

Measured FPS Breakdown

The complete measured FPS data is as follows:

3840x2160 (4K):

• High: 30 FPS average
• Low: 45 FPS average
• Medium: 37 FPS average (32 min, 43 max)
• Ultra: 19 FPS average

2560x1440 (1440p):

• High: 49 FPS average
• Low: 73 FPS average
• Medium: 60 FPS average (51 min, 69 max)

• High: 68 FPS average
• Low: 102 FPS average
• Medium: 83 FPS average (71 min, 96 max)
• Ultra: 43 FPS average

The 1080p results show a clear hierarchy: Low > Medium > High > Ultra, with a 59 FPS spread between the highest and lowest settings. At 1440p, the spread narrows to 42 FPS, and at 4K it is only 26 FPS, confirming the GPU’s diminishing ability to differentiate between quality presets as resolution increases. The Medium preset’s min/max data at each resolution provides insight into frame consistency, with the 1080p result showing the tightest range relative to its average.

The jump from 1080p Medium (83 FPS) to 1440p Medium (60 FPS) represents a 28% drop, while the jump from 1440p Medium to 4K Medium (37 FPS) is a 38% drop. This accelerating decline highlights the non-linear relationship between pixel count and rendering load, with the RX 580’s 256-bit memory bus unable to keep pace with the 4K resolution’s bandwidth demands.
