Downfall

# Downfall with AMD Ryzen 7 9800X3D + NVIDIA GeForce RTX 3080 Ti

The AMD Ryzen 7 9800X3D paired with the NVIDIA GeForce RTX 3080 Ti produces a fascinating performance profile in Downfall, a 2016 horror title that clearly responds differently to resolution and settings changes than modern AAA releases. This combination ranks 442nd out of 1,741 tested combos in this game, placing it in the top 25% of all configurations. The measured frame rates reveal a system that can push well beyond 300 FPS at 1080p Low, yet drops to under 60 FPS at 4K Ultra — a spread that tells a compelling story about where the bottleneck shifts as workload increases.

Resolution Scaling

The frame rate scaling from 1080p to 4K shows a dramatic, non-linear relationship that points to the GPU becoming the primary constraint at higher resolutions. At Low settings, the drop from 312.2 FPS at 1080p to 224.7 FPS at 1440p represents a 28% reduction, and then a further decline to 140.2 FPS at 4K — a 38% additional drop. This progressive degradation suggests that the RTX 3080 Ti's compute resources are being increasingly taxed as pixel count grows.

At High settings, the pattern shifts even more dramatically. The 1080p result of 209.1 FPS drops to 148.1 FPS at 1440p (a 29% decrease), and then to 90.8 FPS at 4K (a 39% further decline). The consistency of these percentage drops across both Low and High settings — roughly 28-29% for the first step and 38-39% for the second — indicates that the scaling behavior is largely resolution-driven rather than settings-driven. This is characteristic of a game where the rendering pipeline becomes more pixel-bound at higher resolutions.

Ultra settings reveal the steepest scaling curve. From 130.3 FPS at 1080p, the frame rate falls to 92.4 FPS at 1440p (29% drop), and then to 58.5 FPS at 4K (37% drop). The fact that 4K Ultra nearly halves the 1080p Ultra performance suggests that the combination of maximum visual fidelity and 4K resolution pushes the GPU to its limits, while the CPU still has headroom to spare.

GPU Role

The RTX 3080 Ti brings substantial resources to Downfall: 12 GB of GDDR6X memory on a 384-bit bus delivering 912.4 GB/s of bandwidth, with 10,240 shading units and 80 RT cores based on the Ampere architecture. The GPU's boost clock of 1665 MHz and 34.10 TFLOPS of FP32 compute power are key factors in the high frame rates observed at lower resolutions.

The memory subsystem appears particularly relevant for this game. The 12 GB VRAM capacity and the 912.4 GB/s bandwidth likely prevent any memory-related bottlenecks even at 4K Ultra, where the frame rate of 58.5 FPS is still respectable. The GPU's pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s provide the raw throughput needed to maintain the measured performance across all settings presets.

Compared to its nearest rivals, the RTX 3080 Ti sits close to the RTX 3090, which has an average benchmark score only 0.5% higher. The AMD Radeon Pro 5300 scores 0.9% higher, while the RTX 5070 is 1.1% ahead and the Tesla M40 leads by 1.6% — though these are synthetic benchmark comparisons, not game-specific measurements. The GPU's 83rd percentile ranking among all GPUs underscores that while it is not the absolute fastest, it remains a high-end part capable of delivering the strong results seen in the measured data.

The 8nm process node from Samsung packs 28,300 million transistors into a 628 mm² die, giving the RTX 3080 Ti a transistor density of 45.1 million per square millimeter. This hardware configuration, combined with the 350W TDP, explains why the card can sustain high frame rates at 1440p but begins to struggle at 4K with Ultra settings.

CPU Role

The AMD Ryzen 7 9800X3D provides the computational foundation for this combination, with 8 cores and 16 threads running at a 4.70 GHz base clock and 5.20 GHz boost clock. This Zen 5 architecture on the 4nm TSMC process node features 96 MB of shared L3 cache, which is likely beneficial for Downfall's horror game workloads that may involve frequent data access patterns.

The CPU's benchmark results reveal exceptional single-threaded and multi-threaded performance. The Cinebench R23 multi-core score of 34,004 and single-core score of 4,800 demonstrate the processor's capability to handle demanding workloads. The 3DMark scores show strong scaling from 2 threads (2,394) to max threads (10,067), indicating efficient multi-core utilization.

At 1080p with Low settings, the system achieves 312.2 FPS, which suggests the CPU is not limiting performance at this resolution. The fact that frame rates continue to scale upward from 1080p Low to 1080p Medium (253.3 FPS) and 1080p High (209.1 FPS) indicates that even at 1080p, the GPU is the primary constraint once settings increase. The CPU's 90th percentile ranking among all CPUs, with an average benchmark score of 37,780, places it just 0.1% behind the Intel Xeon 6353P and 0.6-0.7% behind the Core i9-13900HK and Core i5-13600KF.

The 89.6 GB/s memory bandwidth and DDR5 support provide a solid foundation for feeding the GPU, and the 24 PCIe Gen 5 lanes offer ample bandwidth for the RTX 3080 Ti's PCIe 4.0 x16 interface. The CPU's TDP of 120W suggests efficient power delivery, allowing sustained boost clocks during extended gaming sessions.

How This Combo Ranks

This specific combination of the Ryzen 7 9800X3D and RTX 3080 Ti achieves a rank of 442 out of 1,741 tested combos in Downfall, placing it in the 74th percentile of all configurations. This is a strong showing, though not exceptional — the data suggests that while both components are individually high-performing, the pairing may not extract the absolute maximum potential from either part in this particular game.

The ranking position relative to the component percentiles is notable. The CPU sits at the 90th percentile among all CPUs, while the GPU ranks at the 83rd percentile. The combo's 74th percentile ranking in-game is lower than either component's individual percentile, which indicates that Downfall may not fully utilize the capabilities of this hardware pairing. This could be due to the game's age (released in 2016) and its rendering engine not being optimized for newer hardware architectures.

The 1,741 total tested combos provide a broad comparison base, and the 442nd rank means there are 1,299 combinations that perform worse in this game. This places the combo solidly in the upper quartile, but the gap between the component percentiles and the game-specific rank suggests that other pairings might extract more performance from these components in other titles.

Settings Recommendations

At 1080p, all settings presets deliver playable frame rates, with even Ultra hitting 130.3 FPS. For players with 1080p displays, Ultra settings provide the best visual experience while maintaining frame rates well above the 60 FPS threshold. The 312.2 FPS at Low settings demonstrates the system's capability to drive high-refresh-rate monitors, but the visual compromise is likely unnecessary given the strong Ultra performance.

For 1440p, the High preset at 148.1 FPS offers an excellent balance between visual quality and performance. Ultra at 92.4 FPS remains playable and provides the maximum visual fidelity, while Medium at 183.9 FPS is ideal for high-refresh-rate displays. The Low preset at 224.7 FPS is available for competitive play or maximum frame rates.

At 4K, the recommendation becomes more nuanced. High settings at 90.8 FPS provide a smooth experience with good visual quality, while Ultra at 58.5 FPS dips below the 60 FPS threshold but remains playable. Medium at 115.2 FPS offers the best combination of visual fidelity and performance for 4K displays. The data suggests that 4K Ultra is the only preset that pushes the system to its limits, making High or Medium the recommended choices for most players.
