Downfall

The AMD Ryzen 7 5800X3D and AMD Radeon RX 580 pairing in Downfall produces a combination that ranks near the bottom of the tested field, landing at 1616 out of 1741 total combos. The data indicates a system heavily constrained by the graphics card, where the CPU’s substantial compute resources are largely left unused, particularly at higher resolutions. This analysis breaks down the measured performance to show exactly where the bottleneck lies and what settings offer the most playable experience.

CPU Role — cores, clocks, and how they relate to this game's results

The Ryzen 7 5800X3D brings eight cores and sixteen threads to this pairing, with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. This is a Zen 3 architecture part built on a 7 nm TSMC process, featuring a large 96 MB shared L3 cache. In synthetic benchmarks, the processor demonstrates strong multi-threaded capability, scoring 24,063 in Cinebench R23 multi-core and 28,309 in PassMark multithreaded tests. Its single-thread performance is also healthy, with a Cinebench R23 single-core score of 3,397 and a Geekbench single-core score of 2,116.

However, these CPU strengths do not translate into high frame rates in Downfall because the graphics card becomes the limiting factor well before the processor is stressed. Across all measured settings, the RX 580 produces frame rates that are typical of a mid-range GPU from its generation, and the CPU’s utilization is unlikely to be the constraint. For example, at 1080p Low settings, the system achieves 99.8 FPS average, which is the highest result in the data set. Even at this lowest preset, the frame rate is far below what the 5800X3D could theoretically support in a less GPU-bound scenario.

The 5800X3D’s percentile ranking of 83 among all CPUs places it above average, and its average benchmark score of 26,574 is nearly identical to the AMD EPYC 8024P (26,555) and Intel Core i9-11900K (26,546), with a delta of just 0.1%. This confirms the CPU is a high-end performer. Yet in this specific game, the measured FPS data shows no scenario where the CPU’s capabilities are the primary driver of performance. The bottleneck is consistently the GPU, which is why the FPS drops are so steep when increasing resolution or graphical fidelity.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

*Q: What is the highest average FPS achievable with this CPU/GPU combo in Downfall?*

A: The best result is 99.8 FPS at 1920x1080 resolution with Low settings. This is the only setting/resolution combination that approaches 100 FPS, indicating the GPU’s ceiling for this game.

Q: How does the RX 580 compare to its nearest rivals in synthetic benchmarks?

A: The RX 580’s average benchmark score is 13,559, placing it essentially tied with the NVIDIA GeForce GTX 570 (13,564) and GTX 950 (13,549), with deltas of 0% and 0.1% respectively. It is also within 1.1% of the AMD Radeon Pro 455 (13,416).

Q: Does increasing resolution from 1080p to 4K have a linear impact on performance?

A: No, the impact is severe but non-linear. At High settings, average FPS drops from 68.7 at 1080p to 48.2 at 1440p (a 30% drop) and then to 30.6 at 4K (a 55% drop from 1440p). The scaling shows diminishing returns as resolution increases, confirming GPU-bound behavior.

Q: What is the worst-performing preset for this combo in the measured data?

A: The lowest result is 18.7 FPS at 3840x2160 resolution with Ultra settings. This is the only configuration that falls below 20 FPS, making it effectively unplayable.

Q: How does the 5800X3D’s multi-threaded score compare to its single-threaded score?

A: The CPU scores 24,063 in Cinebench R23 multi-core versus 3,397 in single-core, which is a ratio of about 7:1. This shows strong scaling across its 16 threads, but this capability is not leveraged in Downfall due to the GPU bottleneck.

Q: Given the GPU’s VRAM and bandwidth, what is its theoretical memory performance?

A: The RX 580 has 8 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 256.0 GB/s. The memory clock is 2000 MHz (8 Gbps effective), which is adequate for 1080p gaming but becomes a limiting factor at higher resolutions.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear pattern of GPU-bound scaling across resolutions. At High settings, the combo delivers 68.7 FPS at 1920x1080, which drops to 48.2 FPS at 2560x1440, and further to 30.6 FPS at 3840x2160. This represents a 55.5% reduction in frame rate from 1080p to 4K. The scaling is consistent with a graphics card that is being pushed to its limits by pixel count, rather than a CPU that is struggling to feed frames.

The Low preset tells a similar story, with 99.8 FPS at 1080p, 75.5 FPS at 1440p, and 43.7 FPS at 4K. The percentage drops are 24.3% and 42.1% respectively. This is a classic signature of GPU limitation: as resolution increases, the graphics card’s fill rate and memory bandwidth become the primary constraints. The RX 580’s 256.0 GB/s bandwidth and 42.88 GPixel/s pixel rate are simply insufficient for 4K gaming, even at Low settings.

At Ultra settings, the situation becomes extreme. The system produces 43.4 FPS at 1080p, 32 FPS at 1440p, and only 18.7 FPS at 4K. The drop from 1080p to 4K is 56.9%, which is nearly identical to the High preset’s drop. This consistency across presets reinforces that the GPU is the limiting component. If the CPU were the bottleneck, we would expect the FPS to remain more constant across resolutions, especially at lower settings where the CPU has more headroom. The data does not show that pattern, confirming the RX 580 is the primary constraint.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Ryzen 7 5800X3D and RX 580 ranks 1616 out of 1741 tested combos in Downfall. This places it in the bottom 7% of all tested systems, which is a poor result for a CPU that ranks in the 83rd percentile among all processors. The disparity between the CPU’s high synthetic standing and the combo’s low game ranking is explained by the GPU’s modest performance.

The RX 580’s percentile ranking of 53 among all GPUs puts it near the median, but its average benchmark score of 13,559 is barely above the lowest-scoring rivals in its immediate vicinity. The combo rank of 1616 suggests that most other pairings in the database use a more capable graphics card, even if their CPUs are weaker. This is a common pattern in benchmark databases: the GPU determines the overall gaming rank, and this pairing’s rank reflects the GPU’s age and performance class.

The data shows that the CPU is not the issue. The 5800X3D’s nearest rivals in synthetic benchmarks include the Intel Core i9-11900K and AMD Ryzen 5 7600, with deltas of 0.1% and -0.2% respectively. These are all high-end processors that would likely rank much higher if paired with a modern GPU. The fact that this combo ranks so low is a direct consequence of the RX 580’s limitations, not the CPU’s.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a complete picture of performance across all settings and resolutions. At 1920x1080, the combo achieves 99.8 FPS on Low, 82.3 FPS on Medium, 68.7 FPS on High, and 43.4 FPS on Ultra. The 1080p Low result is the only configuration that exceeds 90 FPS, and it represents the best-case scenario for this hardware.

At 2560x1440, the numbers drop to 75.5 FPS on Low, 60.6 FPS on Medium, 48.2 FPS on High, and 32 FPS on Ultra. The 1440p Medium result of 60.6 FPS is notable because it is the only 1440p configuration that stays above 60 FPS. This suggests that players with 1440p monitors should stick to Medium settings for a smooth experience.

At 3840x2160, the performance falls to 43.7 FPS on Low, 36.8 FPS on Medium, 30.6 FPS on High, and 18.7 FPS on Ultra. The 4K results are uniformly poor, with even the Low preset failing to reach 45 FPS. The Ultra setting at 4K produces a near-unplayable 18.7 FPS, confirming that this resolution is not viable for this combo in Downfall.

Across all resolutions, the delta between Low and Ultra settings is significant. At 1080p, the difference is 56.4 FPS (from 99.8 to 43.4). At 1440p, the difference is 43.5 FPS (from 75.5 to 32). At 4K, the difference is 25 FPS (from 43.7 to 18.7). These deltas show that the GPU’s performance scales predictably with graphical load, further confirming the GPU-bound nature of this pairing.

Settings Recommendations — which preset gives the best experience per the measured rows

For 1920x1080 gaming, the High preset at 68.7 FPS offers the best balance of visual quality and performance. The Low preset provides a higher frame rate of 99.8 FPS, but the visual downgrade is substantial. The Medium preset at 82.3 FPS is a middle ground, but High’s 68.7 FPS is still above the 60 FPS threshold and offers better image quality. Ultra at 43.4 FPS is playable but dips below the smoothness threshold, making High the recommended choice.

For 2560x1440, the Medium preset at 60.6 FPS is the only option that maintains a playable frame rate. The High preset at 48.2 FPS is noticeably less smooth, and the Low preset at 75.5 FPS sacrifices too much visual fidelity. Ultra at 32 FPS is not recommended for action-oriented gameplay. The data clearly supports Medium as the optimal 1440p setting.

For 3840x2160, the results are uniformly poor, and the data suggests avoiding this resolution entirely. The Low preset at 43.7 FPS is the best of a bad set, but it still falls below the 60 FPS target. The Medium preset at 36.8 FPS and High at 30.6 FPS are both choppy, while Ultra at 18.7 FPS is unplayable. If 4K is required, the Low preset is the only option, but the experience will be suboptimal.

Overall, the best experience in Downfall with this combo is at 1080p with High settings, yielding 68.7 FPS. This provides a smooth frame rate while retaining enough visual detail to enjoy the horror atmosphere. For users with 1440p monitors, Medium settings at 60.6 FPS is the recommended compromise.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 580 is built on the Polaris 20 chip using GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It has 8 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 256.0 GB/s. The GPU’s base clock is 1257 MHz with a boost clock of 1340 MHz, and its memory runs at 2000 MHz (8 Gbps effective). These specifications place it in the mid-range segment of its generation.

The GPU’s 2,304 shading units, 144 texture mapping units, and 32 ROPs deliver a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s. Its FP32 performance is 6.175 TFLOPS. These figures explain the measured FPS results: the GPU is capable of handling 1080p gaming at moderate settings, but its fill rate and memory bandwidth are insufficient for 4K or high-ultra settings.

The RX 580’s average benchmark score is 13,559, which places it in the 53rd percentile among all GPUs. Its nearest rivals in synthetic benchmarks are the NVIDIA GeForce GTX 570 (13,564) and GTX 950 (13,549), with deltas of 0% and 0.1% respectively. This shows that the RX 580 is a solid mid-range performer for its era, but it is far from the top of the performance stack. In Downfall, this translates to the measured FPS data, where the GPU consistently becomes the limiting factor.

The 8 GB VRAM is sufficient for 1080p and 1440p gaming, but the 256.0 GB/s bandwidth becomes a constraint at 4K. The GPU’s TDP of 185 W and dual-slot design are typical for its class, and its PCIe 3.0 x16 interface is adequate for the Polaris architecture. The data shows that the GPU’s performance is the primary determinant of the combo’s low rank, and upgrading this component would yield significant FPS improvements across all tested settings.
