Downfall

# Downfall with AMD Ryzen 5 5500X3D + Intel Arc B580

This combination pairs AMD's 6-core, 12-thread Ryzen 5 5500X3D with Intel's Arc B580 graphics card, producing a system that handles the 2016 horror title Downfall with consistent playable frame rates across most settings, though the data reveals a clear ceiling at 4K Ultra where performance drops sharply. The CPU, built on Zen 3 (Vermeer) architecture at a 7nm process, operates with a base clock of 3.00 GHz and boost clock of 4.00 GHz, while the GPU, based on the Xe2-HPG Battlemage architecture at 5nm, runs at a flat 2670 MHz for both base and boost. Together they deliver results that place this specific pairing at rank 2196 out of 2928 tested combinations in Downfall, a mid-pack position that reflects balanced but not exceptional performance for this older horror title.

CPU Role

The AMD Ryzen 5 5500X3D provides six physical cores with twelve threads via simultaneous multithreading, a configuration that proves more than adequate for Downfall's workload. The CPU's 96 MB of shared L3 cache is the standout feature here, a large pool that helps maintain consistent frame pacing in a game that often loads environmental assets during exploration. The processor's Passmark multithread score of 20363 and single-thread score of 2941 indicate solid general-purpose capability, placing it in the 85th percentile among all CPUs tested. In the context of Downfall, which is not heavily threaded, the single-thread performance matters more, and the data shows this CPU delivers enough headroom to avoid bottlenecking the Arc B580 at lower resolutions.

The CPU's nearest rivals in synthetic benchmarks include the AMD Ryzen 5 5600F with an average score of 36945 (0.2% lower), the AMD Ryzen AI 7 PRO 450 at 37093 (0.2% higher), the Intel Core Ultra 5 225 at 36938 (0.2% lower), and the Intel Core i9-12900T at 37112 (0.3% higher). These deltas are negligible, meaning the 5500X3D sits in a performance tier where no single competitor holds a meaningful synthetic advantage. For Downfall specifically, the CPU's role becomes more pronounced at 1080p, where the measured frame rates are highest and the processor must feed the GPU efficiently. The 3.00 GHz base clock rising to 4.00 GHz boost provides adequate responsiveness, though the CPU is not unlocked for multiplier adjustments, limiting overclocking headroom. The 105W TDP with DDR4 dual-channel memory support at 51.2 GB/s bandwidth rounds out a platform that is competent but not current-generation for this game.

Settings Recommendations

Examining the measured FPS data across all resolutions and settings, the Medium preset emerges as the most balanced choice for this combination. At 1920x1080 Medium, the system delivers 151 average FPS with a minimum of 128 and maximum of 174, which is smooth and well above typical display refresh rates. The 2560x1440 Medium result of 108 average FPS (min 92, max 124) remains highly playable, and even at 3840x2160 Medium the system holds 67 average FPS with a minimum of 57, which stays within acceptable bounds for a horror game where slower pacing is common. The Medium preset appears to be the sweet spot because it avoids the steep drop seen when moving to Ultra while providing substantially better visual quality than Low.

The Ultra preset is difficult to recommend for this pairing. At 1080p Ultra the average FPS drops to 77, which is still playable but represents a 49% reduction from Medium. At 1440p Ultra the average falls to 55 FPS, and at 4K Ultra it plummets to 34 average FPS, which is below the threshold for comfortable gameplay in a tense horror atmosphere. The High preset sits between these extremes: 124 FPS at 1080p, 88 FPS at 1440p, and 55 FPS at 4K. For users prioritizing visual fidelity over frame rate, High at 1080p or 1440p offers a reasonable compromise, but Medium provides the best overall experience by maintaining high frame rates with only modest visual sacrifices. The Low preset, while delivering 185 FPS at 1080p, 132 FPS at 1440p, and 82 FPS at 4K, sacrifices too much visual quality for a game that relies on atmosphere and environmental detail.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals where the bottleneck shifts between CPU and GPU. At 1080p Medium, the system achieves 151 FPS, which drops to 108 FPS at 1440p (a 28.5% reduction) and then to 67 FPS at 4K (a further 38% reduction). This scaling pattern indicates that the GPU begins to become the limiting factor as resolution increases, but the CPU maintains sufficient headroom throughout. The largest relative drop occurs between 1440p and 4K, suggesting the Arc B580's rendering capabilities are taxed most heavily at the highest resolution. At 1080p Low, the 185 FPS result suggests the CPU is still able to push very high frame rates when the GPU load is light, but the 82 FPS at 4K Low shows the GPU's pixel throughput becomes the constraint.

Looking at the Ultra settings across resolutions, the scaling is steeper: 77 FPS at 1080p, 55 FPS at 1440p (a 28.6% drop), and 34 FPS at 4K (a 38.2% drop from 1440p). This consistent pattern across presets indicates that the Arc B580's raw fill rate and shading capability are the primary limiters at higher resolutions, while the Ryzen 5 5500X3D's cache and core configuration handle the game logic without becoming a significant constraint. The 12 GB of GDDR6 memory on the GPU, with 456.0 GB/s bandwidth, provides ample capacity for Downfall's textures, so memory is not the limiting factor. Instead, the 2560 shading units and 80 ROPs determine the pixel throughput ceiling, which explains why frame rates scale so predictably with resolution.

GPU Role

The Intel Arc B580 brings 12 GB of GDDR6 memory on a 192-bit bus with 456.0 GB/s bandwidth, which is more than sufficient for Downfall's texture and geometry requirements. The GPU's 2560 shading units, 160 texture mapping units, and 80 render output units define its rasterization throughput, with a pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s. The 13.67 TFLOPS of FP32 compute power provides ample shading capability for this 2016 title, and the 20 ray tracing cores are present but largely unused in a game that predates widespread RT adoption. The GPU's 2670 MHz clock speed is uniform across base and boost, indicating a fixed operating point that delivers consistent performance.

In synthetic benchmarks, the Arc B580 scores 15748 in Passmark G3D and 7729 in GPU compute, with a DirectX 12 score of 76 and DirectX 11 score of 128. The Vulkan score of 109672 and OpenCL score of 92821 from Geekbench show strong compute capabilities. The GPU sits in the 68th percentile among all GPUs, with an average benchmark score of 23021. Its nearest rivals include the AMD Radeon RX 580 2048SP (23061, 0.2% higher), NVIDIA GeForce RTX 2080 (22895, 0.6% lower), NVIDIA GeForce RTX 3080 (23172, 0.7% higher), and NVIDIA P106-100 (23249, 1% higher). This tight clustering means the Arc B580 performs nearly identically to several well-known cards in synthetic tests, though real-world gaming performance in Downfall shows the expected resolution scaling patterns.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its strongest performance. Low settings produce 185 average FPS, Medium delivers 151 average FPS with a minimum of 128 and maximum of 174, High achieves 124 average FPS, and Ultra drops to 77 average FPS. The gap between Medium and High is 27 FPS (17.9% reduction), while the gap between High and Ultra is 47 FPS (37.9% reduction), showing that Ultra carries a disproportionate performance cost. The 2560x1440 results follow a similar pattern: Low at 132 FPS, Medium at 108 FPS (min 92, max 124), High at 88 FPS, and Ultra at 55 FPS. The Medium preset maintains a 92 FPS minimum, which is comfortable for most displays, while Ultra dips to levels that may cause noticeable stutter in fast-moving scenes.

At 3840x2160, the GPU's limitations become clear. Low settings still manage 82 average FPS, which is playable, but Medium drops to 67 FPS with a minimum of 57, and High falls to 55 FPS. Ultra at 4K is the weakest result in the entire dataset at 34 average FPS, which is below the threshold for smooth gameplay in most scenarios. The progression from 1080p Low (185 FPS) to 4K Low (82 FPS) represents a 55.7% reduction, while the same progression for Medium (151 to 67 FPS) is a 55.6% reduction, indicating consistent scaling behavior across presets. The minimum FPS values recorded only for Medium settings show the system maintains 128 FPS at 1080p, 92 FPS at 1440p, and 57 FPS at 4K, which are all respectable minimums that suggest stable frame delivery without severe dips.

How This Combo Ranks

This specific combination of AMD Ryzen 5 5500X3D and Intel Arc B580 ranks 2196 out of 2928 tested combos in Downfall, placing it in the 75th percentile from the bottom, meaning roughly one-quarter of tested systems perform worse. This rank is somewhat lower than the individual components might suggest, given that the CPU sits in the 85th percentile among all CPUs and the GPU in the 68th percentile among all GPUs. The discrepancy likely stems from the game's age and its specific optimization patterns, which may favor certain hardware combinations over others. The CPU's synthetic nearest rivals, such as the AMD Ryzen 5 5600F and Intel Core Ultra 5 225, show essentially identical average scores with deltas around 0.2%, so the processor choice is unlikely to be the differentiator in ranking.

The GPU's position relative to its nearest rivals in synthetic benchmarks shows it performs nearly identically to the NVIDIA GeForce RTX 2080 and RTX 3080, with deltas of 0.6% and -0.7% respectively. This suggests the Arc B580 is a capable mid-to-high-range card for this title, but the overall combo rank of 2196 indicates that other tested systems with similar or better GPUs achieve higher frame rates in Downfall. The rank reflects the complete system performance, and while this pairing delivers playable frame rates at most settings, it does not stand out among the 2928 tested combinations. For users with this hardware, the practical takeaway is that Medium settings at 1080p or 1440p provide the best balance of visual quality and performance, while 4K should be reserved for Low or Medium presets if smooth frame rates are prioritized.
