Downfall

# Downfall with AMD Ryzen 5 5500X3D + AMD Radeon RX 570

This pairing combines AMD's six-core Zen 3 Vermeer processor with the Polaris 20-based Radeon RX 570, a GPU that has been end-of-life since its 2017 release. The data shows a combination that is heavily GPU-limited at higher resolutions, with the CPU's 96 MB of shared L3 cache and 3.00 GHz base / 4.00 GHz boost clocks providing ample headroom for the RX 570 at 1080p, but the gap widens dramatically as resolution increases. The combo ranks 2797th out of 2928 tested combinations in Downfall, placing it in the bottom 4.5% of all tested systems for this horror title.

Resolution Scaling

The measured FPS data reveals a stark resolution scaling pattern that clearly identifies the RX 570 as the primary bottleneck. At 1080p High settings, the combo delivers 62 FPS average. Moving to 1440p High drops that to 44 FPS, a 29% reduction. At 4K High, the average falls to 27 FPS, which represents a 56% drop from the 1080p figure. This steep decline is characteristic of a GPU that runs out of pixel throughput and memory bandwidth as the pixel count rises.

The RX 570's 4 GB of GDDR5 memory on a 256-bit bus provides 224.0 GB/s of bandwidth. At 4K, this becomes a serious constraint. The 4K Ultra setting produces only 17 FPS average, which is unplayable by any standard. Even at 4K Low, the system can only muster 41 FPS, indicating that the GPU's raw compute limits — 5.095 TFLOPS FP32 and 32 ROPs — are simply insufficient for 4K rendering in this title.

Comparing the scaling from 1080p to 1440p versus 1440p to 4K shows the performance collapse accelerating. At Low settings, 1080p yields 92 FPS, 1440p yields 66 FPS, and 4K yields 41 FPS. The percentage drops are 28% and 38% respectively, showing that each resolution step costs more relative performance. This non-linear degradation is a classic sign of the GPU hitting memory bandwidth and fill-rate walls simultaneously.

The 1080p to 4K scaling at Medium settings tells a similar story: 75 FPS at 1080p, 54 FPS at 1440p, and 33 FPS at 4K. The min/max data available for Medium settings shows 64-86 FPS at 1080p, 46-62 FPS at 1440p, and 28-38 FPS at 4K. The frame time consistency degrades as well, with the gap between min and max FPS narrowing in absolute terms but the variance becoming more significant relative to the average.

CPU Role

The AMD Ryzen 5 5500X3D brings six cores and twelve threads to this pairing, built on the Zen 3 architecture using TSMC's 7 nm process. Its 96 MB of shared L3 cache is a standout feature — a massive pool that helps with game data locality. The CPU's PassMark single-thread score of 2941 and multithread score of 20363 place it in the 85th percentile among all CPUs, indicating strong general-purpose performance.

In Downfall, a horror title, the CPU's role appears secondary to the GPU. The data supports this: at 1080p Low, the system reaches 92 FPS, but the CPU is capable of far more. The Ryzen 5 5500X3D's nearest rival, the AMD Ryzen 5 5600F, scores 36945 in average benchmark versus the 5500X3D's 37018, a delta of just 0.2%. This places the 5500X3D effectively at parity with its closest competitor, while being 0.2% ahead of the Intel Core Ultra 5 225 and 0.3% behind the Intel Core i9-12900T.

The CPU's 3.00 GHz base clock and 4.00 GHz boost clock, combined with DDR4 memory support running dual-channel at 51.2 GB/s bandwidth, provide solid fundamentals. The 105 W TDP indicates a power-hungry chip, but the performance per clock from Zen 3 is well established. For Downfall, the CPU's 12 threads are more than sufficient — the game's horror genre typically doesn't demand extreme multi-core scaling, and the 5500X3D's strong single-thread performance (2941 PassMark) handles game logic and physics without becoming a limiting factor.

The PassMark physics score of 2282 and floating-point math score of 34511 suggest the CPU can handle complex game calculations. The integer math score of 60033 and extended instructions score of 15925 round out a profile that is mid-pack for modern CPUs but far ahead of what this GPU pairing requires. At 4K Ultra, where the system drops to 17 FPS, the CPU is almost certainly idle waiting on the GPU — the frame rate is so low that CPU overhead would be negligible.

GPU Role

The AMD Radeon RX 570 is the clear performance limiter in this combination. Based on the Polaris 20 chip with GCN 4.0 architecture, this GPU features 2048 shading units, 128 TMUs, and 32 ROPs. Its clocks run at 1168 MHz base and 1244 MHz boost, with memory at 1750 MHz (7 Gbps effective) across a 256-bit bus. The 4 GB GDDR5 frame buffer is the most significant constraint at higher resolutions.

The GPU's benchmark profile shows a 74th percentile ranking among all GPUs, with an average benchmark score of 28766. Its closest rival, the AMD Radeon RX 6800M, scores 28874, a delta of -0.4%, meaning the RX 570 is slightly behind. The RX 470 trails by 0.8%, while the NVIDIA Quadro RTX 8000 is 1.2% behind. This places the RX 570 in a narrow performance band where small deltas separate it from its immediate competitors.

In Downfall, the RX 570's 4 GB VRAM becomes a bottleneck at 4K. The 224.0 GB/s bandwidth is simply not enough to feed the render pipeline at 3840x2160. The pixel rate of 39.81 GPixel/s and texture rate of 159.2 GTexel/s are respectable for 1080p but fall short at higher resolutions. The 14 nm process node from GlobalFoundries means the GPU runs at 150 W TDP, requiring a 450 W suggested PSU and a single 6-pin power connector.

The GPU's DirectX 12 (12_0) support and Vulkan 1.3 capability are adequate for Downfall, but the architecture's age shows in the scaling pattern. At 1080p, the RX 570 delivers playable frame rates: 92 FPS at Low, 75 FPS at Medium, 62 FPS at High, and 39 FPS at Ultra. The Ultra setting at 1080p is borderline, but the GPU's limitations become severe at 1440p and worse at 4K.

Measured FPS Breakdown

At 1920x1080, the combo delivers usable performance across most settings. Low settings produce 92 FPS average, which is smooth for a horror game. Medium settings yield 75 FPS with a min of 64 and max of 86, showing reasonable frame time consistency. High settings drop to 62 FPS, still playable. Ultra settings fall to 39 FPS, which is below the ideal threshold for smooth gameplay but technically playable.

Moving to 2560x1440, the GPU strain becomes evident. Low settings still manage 66 FPS, but Medium drops to 54 FPS (min 46, max 62). High settings produce 44 FPS, and Ultra falls to 28 FPS. The 1440p results show that the RX 570 is stretched thin at this resolution — even Low settings cannot maintain the 60+ FPS that most players would prefer.

At 3840x2160, the results are largely unplayable. Low settings yield 41 FPS, Medium 33 FPS (min 28, max 38), High 27 FPS, and Ultra 17 FPS. The 4K Ultra result of 17 FPS is a slideshow, and even 4K Low at 41 FPS is below the threshold for a smooth experience. The data indicates that this pairing should be used at 1080p for any serious gaming, with 1440p only viable at Low settings.

The settings scaling at each resolution is informative. At 1080p, the gap between Low and Ultra is 53 FPS (92 vs 39). At 1440p, that gap narrows to 38 FPS (66 vs 28). At 4K, the gap shrinks to 24 FPS (41 vs 17). This compression of the settings range at higher resolutions confirms that the GPU is the bottleneck — when the GPU is saturated, changing settings has less impact because the renderer is already limited by raw throughput.

How This Combo Ranks

The combo ranks 2797th out of 2928 tested combinations in Downfall, placing it in the bottom 4.5% of all systems tested. This is a low ranking that reflects the GPU's age and the demands of the game at higher resolutions. The CPU's 85th percentile ranking among all CPUs contrasts sharply with the GPU's 74th percentile, but in gaming, the GPU typically dominates the ranking.

This ranking means that the vast majority of tested systems outperform this pairing in Downfall. The RX 570, despite being a capable 1080p card in its era, is now outclassed by modern GPUs. The CPU, however, is not the issue — the Ryzen 5 5500X3D's performance is more than adequate for this game, as evidenced by the 1080p Low result of 92 FPS.

For context, the nearest rival comparisons show that the CPU is well-positioned: 0.2% ahead of the Ryzen 5 5600F, 0.2% ahead of the Intel Core Ultra 5 225, and 0.3% behind the Intel Core i9-12900T. The GPU sits in a similar tight band: 0.4% behind the RX 6800M, 0.7% ahead of the R9 M295X, 0.8% behind the RX 470, and 1.2% ahead of the Quadro RTX 8000. These narrow deltas suggest that neither component is an outlier — they perform as expected for their respective tiers.

The ranking of 2797 out of 2928 is a strong signal that this combo is not suited for Downfall at higher settings or resolutions. However, the 1080p results show that the system is functional for the game at Medium settings, where it achieves 75 FPS. This suggests the combo can handle the horror title adequately if the user accepts 1080p as the target resolution.

FAQ

Q: Can this combo run Downfall at 60 FPS?

A: Yes, but only at 1080p with Low or Medium settings. The data shows 92 FPS at 1080p Low and 75 FPS at 1080p Medium. At 1080p High, it drops to 62 FPS, which is still above 60. At 1440p, no setting achieves 60 FPS — the best is 66 FPS at Low, but Medium drops to 54 FPS.

Q: Is the CPU or GPU the limiting factor in this system?

A: The GPU is clearly the limiting factor. The CPU's PassMark scores (2941 single-thread, 20363 multithread) place it in the 85th percentile, while the GPU's 74th percentile ranking and the steep FPS drops from 1080p to 4K indicate GPU saturation. At 4K Ultra, the system produces only 17 FPS, which no CPU could compensate for.

Q: What is the best resolution and settings for this combo?

A: The data suggests 1080p Medium as the optimal balance, yielding 75 FPS with a min of 64 and max of 86. 1080p High at 62 FPS is also viable. For a smoother experience, 1080p Low at 92 FPS is the highest frame rate available. 1440p is only playable at Low (66 FPS), and 4K should be avoided entirely.

Q: How does the Ryzen 5 5500X3D compare to its nearest rivals?

A: The CPU scores 37018 in average benchmark, which is 0.2% ahead of the AMD Ryzen 5 5600F (36945), 0.2% ahead of the Intel Core Ultra 5 225 (36938), and 0.3% behind the Intel Core i9-12900T (37112). It is effectively at parity with all three, making it a well-rounded mid-range choice.

Q: Is the RX 570's 4 GB VRAM sufficient for Downfall?

A: At 1080p, yes — the game runs at 62 FPS on High settings. At 1440p and 4K, the 4 GB VRAM combined with 224.0 GB/s bandwidth becomes a constraint, as shown by the severe frame rate drops. The 4K Ultra result of 17 FPS strongly indicates VRAM and bandwidth starvation.

Q: What does the combo's rank of 2797 out of 2928 mean?

A: It means this pairing performs worse than approximately 95.5% of all tested combos in Downfall. This low ranking is driven primarily by the GPU, which is end-of-life and outclassed by modern hardware. The CPU is not the weak link — the system's 1080p performance confirms the processor can feed the GPU adequately.
