Downfall

# Downfall with AMD Ryzen 7 5800X3D + NVIDIA GeForce RTX 3080 Ti

The AMD Ryzen 7 5800X3D paired with the NVIDIA GeForce RTX 3080 Ti produces a fascinating dataset in Downfall, a 2016 horror title that clearly scales across resolutions and presets in ways that reveal both component strengths and bottlenecks. The measured FPS ranges from a demanding 57.6 at 4K Ultra to a blistering 310.2 at 1080p Low, and the shape of those numbers tells a story about where this combo excels and where it strains.

Resolution Scaling

The resolution scaling behavior in Downfall shows a classic pattern, but with some notable wrinkles. Moving from 1080p to 1440p at High settings drops average FPS from 209.8 to 149.5, a reduction of roughly 29%. The jump from 1440p to 4K at High is even steeper, falling from 149.5 to 95.9, another 36% decline. This progressive degradation suggests the GPU is becoming the primary limiting factor as pixel count rises.

At Low settings, the scaling is even more dramatic. The 1080p Low result of 310.2 FPS falls to 221.2 at 1440p (a 29% drop) and then to 140.8 at 4K (a 36% drop from 1440p). The fact that the percentage losses are nearly identical between High and Low presets across resolution steps indicates that resolution is the dominant variable here, not the graphics settings themselves.

Ultra settings tell a different story. At 4K Ultra, the combo manages only 57.6 FPS, while 1440p Ultra hits 94.5 and 1080p Ultra reaches 134.1. The gap between 1080p Ultra and 4K Ultra represents a 57% reduction, which is larger than the drops seen at other presets. This suggests that Ultra settings amplify the resolution penalty, likely through heavier shader and texture workloads that disproportionately tax the GPU at higher pixel counts.

The data implies that at 1080p, the CPU has enough headroom to push very high frame rates, but the RTX 3080 Ti still dominates the workload. At 4K, the GPU is unquestionably the bottleneck, as even Low settings produce only 140.8 FPS compared to 310.2 at 1080p Low. The scaling between 1440p and 4K is particularly severe across all presets, indicating that the 4K resolution pushes the GPU beyond its comfortable operating range in this title.

Settings Recommendations

For a 60 FPS target, Ultra settings are viable only at 1080p, where the combo delivers 134.1 FPS. At 1440p, Ultra drops to 94.5 FPS, which remains smooth, but 4K Ultra falls to 57.6 FPS, barely above the threshold. For 4K gaming, High settings are the clear choice, delivering 95.9 FPS with a substantial 66% improvement over Ultra.

The Medium preset offers an interesting middle ground. At 4K, Medium produces 114.6 FPS, which is 19% higher than High and 99% higher than Ultra. At 1440p, Medium reaches 184.6 FPS, and at 1080p it hits 254.3 FPS. The step from Medium to High costs roughly 16% performance at 4K (114.6 to 95.9), while the step from High to Ultra costs a massive 40% (95.9 to 57.6).

For players seeking maximum frame rates, Low settings at 1080p deliver 310.2 FPS, which is 22% higher than Medium at the same resolution. The jump from Low to Medium at 1080p costs 56 FPS, while Medium to High costs another 45 FPS. At 1440p, Low produces 221.2 FPS, which is still exceptionally high and likely exceeds the refresh rate of most monitors.

The data suggests that High at 4K is the optimal balance for visual quality and performance, offering 95.9 FPS without the steep penalty of Ultra. At 1080p, even Ultra settings are well within comfortable territory at 134.1 FPS, making preset choice more about visual preference than performance necessity.

How This Combo Ranks

The AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 3080 Ti combination ranks 405th out of 1741 tested combos in Downfall, placing it in the top 23% of all configurations. This is a strong result, though not exceptional, which aligns with the measured FPS data showing capable but not class-leading performance.

The CPU itself holds the 83rd percentile among all processors, with an average benchmark score of 26574. Its nearest rivals include the AMD EPYC 8024P with a score of 26555 (0.1% higher), the Intel Core i9-11900K at 26546 (0.1% higher), the AMD Ryzen 5 7600 at 26617 (0.2% lower), and the Intel Core i9-12900HK at 26672 (0.4% lower). These deltas are remarkably tight, indicating that the 5800X3D is essentially performance-equivalent to a broad range of modern CPUs in synthetic benchmarks.

The GPU also sits at the 83rd percentile among all graphics cards, with an average benchmark score of 41224. Its nearest rivals are the NVIDIA GeForce RTX 3090 at 41441 (0.5% higher), the AMD Radeon Pro 5300 at 41610 (0.9% higher), the NVIDIA GeForce RTX 5070 at 41687 (1.1% higher), and the NVIDIA Tesla M40 at 41897 (1.6% higher). The RTX 3080 Ti trails these competitors by single-digit percentage points, confirming its position as a high-end but not flagship GPU.

The combination's 405th rank out of 1741 suggests that many other pairings achieve better results in Downfall, likely due to more recent GPU architectures or higher-tier CPUs. However, the measured FPS numbers show this combo is far from struggling, particularly at lower resolutions where it demonstrates excellent headroom.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance. Low settings produce 310.2 FPS, Medium reaches 254.3 FPS, High achieves 209.8 FPS, and Ultra manages 134.1 FPS. The progression from Low to Ultra represents a 57% performance reduction, with the largest single drop occurring between High and Ultra at 76 FPS.

At 2560x1440, performance remains strong but shows the expected decline. Low produces 221.2 FPS, Medium hits 184.6 FPS, High reaches 149.5 FPS, and Ultra falls to 94.5 FPS. The gap between Low and Ultra is 127 FPS, or 57%, consistent with the 1080p scaling pattern.

At 3840x2160, the GPU begins to show its limits. Low delivers 140.8 FPS, Medium reaches 114.6 FPS, High achieves 95.9 FPS, and Ultra drops to 57.6 FPS. The Ultra preset at 4K is the only measured configuration below 60 FPS, making it the sole point where this combo fails to maintain smooth gameplay.

The data reveals a consistent pattern: each resolution step costs roughly 29-36% performance at the same settings, while each preset step from Low to Ultra costs approximately 17-40% at the same resolution. The steepest penalty is always the High-to-Ultra transition, which is most pronounced at 4K where it costs 38 FPS.

GPU Role

The NVIDIA GeForce RTX 3080 Ti features 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth. Its GA102 chip packs 10240 shading units, 320 TMUs, and 112 ROPs, with base and boost clocks of 1365 MHz and 1665 MHz respectively. The GPU supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6, making it well-suited for modern titles like Downfall.

The 12 GB VRAM capacity appears sufficient for Downfall at all measured settings, as no memory-related stuttering or performance anomalies are evident in the data. The GPU's pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s provide ample fill rate for the horror game's visuals, even at 4K resolution.

The RTX 3080 Ti's FP32 performance of 34.10 TFLOPS is substantial, but the measured FPS drops at 4K Ultra suggest that the shading workload in Downfall at maximum settings exceeds what this GPU can comfortably handle. The 57.6 FPS result at 4K Ultra indicates the GPU is fully saturated, with no headroom for additional visual effects or higher resolutions.

The GPU's 83rd percentile ranking among all graphics cards, with an average benchmark score of 41224, places it just behind the RTX 3090 by 0.5%. This close margin is reflected in Downfall performance, where the combo achieves strong but not elite results. The RTX 3080 Ti's 350 W TDP and 750 W suggested PSU requirement indicate it is a power-hungry component, but the data shows this power is effectively translated into frame rates.

CPU Role

The AMD Ryzen 7 5800X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer, manufactured on TSMC's 7 nm process. It features 8,850 million transistors on a 74 mm² die, with a base clock of 3.40 GHz and boost clock of 4.50 GHz. The 96 MB of shared L3 cache is the defining feature of the X3D variant, providing substantial cache capacity for gaming workloads.

The CPU's benchmark results are strong but not exceptional. Its Cinebench R23 multicore score of 24063 and single-core score of 3397 demonstrate solid performance, while its Geekbench multicore score of 11061 and single-core score of 2116 confirm balanced capabilities. The passmark multithread score of 28309 and single-thread score of 3234 further validate the CPU's gaming-oriented design.

In Downfall, the CPU appears to be sufficient at all measured resolutions. At 1080p Low, the 310.2 FPS result indicates the CPU can feed the GPU with enough frames to reach very high rates. The fact that performance scales linearly with resolution suggests the CPU is not a bottleneck even at the lowest settings, where CPU overhead is typically most apparent.

The 5800X3D's 105 W TDP and dual-channel DDR4 memory support provide adequate bandwidth for gaming, though the 51.2 GB/s memory bandwidth is modest by modern standards. The CPU's 83rd percentile ranking, with an average benchmark score of 26574, places it in a tight cluster with rivals that are within 0.4% of its performance. This statistical parity suggests that the 5800X3D's cache advantage does not translate into a significant edge in synthetic benchmarks, but its real-world gaming performance in Downfall is clearly strong.
