Downfall

# Downfall with AMD Ryzen 9 9950X3D + NVIDIA GeForce RTX 4080

The AMD Ryzen 9 9950X3D paired with the NVIDIA GeForce RTX 4080 delivers a formidable experience in Downfall, a horror title from 2016 that remains demanding at high resolutions. Measured data across three resolutions and four settings presets reveals a system capable of extreme frame rates at 1080p, with performance scaling that highlights the GPU as the primary constraint as resolution climbs. This combination ranks in the 94th percentile among 3,716 tested combos, placing it firmly in the upper echelon while leaving room for faster configurations above it.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a dramatic and predictable drop in average FPS across all settings. At Low settings, the system delivers 400 FPS at 1080p, which falls to 285 FPS at 1440p (a 28.8% reduction) and then to 178 FPS at 4K (a 55.5% reduction from the 1080p baseline). This steep curve at Low settings indicates that the CPU has ample headroom to feed the GPU, but the RTX 4080's rendering load grows substantially as pixel count quadruples from 1080p to 4K.

At Medium settings, the scaling pattern is similar but slightly compressed: 327 FPS at 1080p, 233 FPS at 1440p, and 145 FPS at 4K. The drop from 1080p to 1440p is 28.7%, nearly identical to the Low preset's percentage, while the 4K figure represents a 55.7% decline from 1080p. This consistency across presets suggests that resolution scaling is largely independent of the settings level, with the GPU's pixel throughput being the dominant factor.

High settings show the same relative behavior: 268 FPS at 1080p, 191 FPS at 1440p, and 119 FPS at 4K. The 1440p figure is 28.7% lower than 1080p, and the 4K figure is 55.6% lower. Ultra settings follow suit with 168 FPS at 1080p, 120 FPS at 1440p, and 74 FPS at 4K. The 1440p drop is 28.6%, and the 4K drop is 56.0%. This tight clustering of percentage drops across all four presets strongly indicates that resolution scaling in Downfall is governed by the GPU's fill rate and memory bandwidth, not by CPU-side bottlenecks or settings-dependent effects.

The frame rate at 4K Ultra, 74 FPS, is the only measured result that dips below the 100 FPS threshold, suggesting that the RTX 4080 begins to feel the strain of Downfall's most demanding configuration. The gap between 4K High (119 FPS) and 4K Ultra (74 FPS) is substantial at 37.8%, indicating that the Ultra preset imposes a heavy load that the GPU cannot fully absorb at 4K. At 1080p, the same settings gap is 37.3% (268 FPS to 168 FPS), showing that the relative cost of Ultra is consistent regardless of resolution, further confirming the GPU-centric scaling behavior.

CPU Role

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor based on the Zen 5 architecture, codenamed Granite Ridge, built on a 4 nm process at TSMC. Its base clock is 4.30 GHz with a boost clock of 5.70 GHz, and it carries 128 MB of L3 cache alongside 1 MB of L2 per core and 80 KB of L1 per core. This cache configuration, combined with the high boost clock, positions the CPU to handle Downfall's single-threaded and lightly threaded workloads with ease.

Benchmark data shows strong single-thread performance: the 3DMark single-thread score is 1,292, and Cinebench R23 single-core reaches 2,259. Geekbench single-core is 3,064. These numbers indicate that the 9950X3D has the per-core strength necessary to avoid bottlenecking the RTX 4080 in a horror game that likely relies on a few heavily utilized threads. The multi-threaded scores are equally impressive, with Cinebench R23 multi-core at 42,018 and Geekbench multi-core at 26,736, but Downfall's engine is unlikely to scale across all 32 threads, making the single-core results more relevant to frame rate delivery.

The CPU's percentile ranking of 95 against all CPUs places it among the top 5% of processors in the database. Its nearest rivals in average benchmark score are the AMD Ryzen 7 PRO 9755 at 75,738 (0.1% higher), the AMD Ryzen 7 PRO 9755X3D at 75,716 (0.1% higher), the AMD EPYC 8224P at 75,582 (0.3% lower), and the Intel Core Ultra 9 285 at 75,488 (0.4% lower). These tiny delta percentages suggest that the 9950X3D is essentially tied with the fastest desktop and server chips available, meaning the CPU is not a limiting factor in Downfall at any tested resolution.

At 1080p Low, the measured 400 FPS represents the absolute ceiling of this combination, and the fact that the frame rate scales down predictably as resolution increases suggests the CPU can maintain high instruction throughput without stalling. The 9950X3D's 89.6 GB/s memory bandwidth on a dual-channel DDR5 interface provides sufficient data flow for the GPU, and the 170 W TDP indicates a high-power part that sustains boost clocks under load. For a horror game that likely features physics, AI, and scripted sequences, the 9950X3D's combination of high clock speeds and large cache ensures that CPU-side frame time spikes are minimized, keeping the measured average FPS figures stable.

GPU Role

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture with the AD103 chip, manufactured on a 5 nm process at TSMC. It features 9,728 shading units, 304 texture mapping units, and 112 raster output pipelines, along with 76 ray tracing cores and 304 tensor cores. The GPU operates at a base clock of 2,205 MHz with a boost clock of 2,505 MHz, and its 16 GB of GDDR6X memory runs at 1,400 MHz with an effective data rate of 22.4 Gbps, delivering 716.8 GB/s of bandwidth across a 256-bit bus.

The RTX 4080's compute capabilities are substantial: FP32 performance is 48.74 TFLOPS, pixel rate is 280.6 GPixel/s, and texture rate is 761.5 GTexel/s. These figures explain the GPU's ability to push high frame rates at 1440p and 4K in Downfall. At 4K Low, the card produces 178 FPS, and at 4K Medium it hits 145 FPS with a minimum of 123 FPS and maximum of 167 FPS. The 4K High setting yields 119 FPS, while 4K Ultra drops to 74 FPS. The gap between Medium and High at 4K (145 to 119 FPS, an 18.0% reduction) is smaller than the gap between High and Ultra (119 to 74 FPS, a 37.8% reduction), suggesting that the Ultra preset introduces effects that heavily tax the GPU's shading and memory subsystems.

The GPU's 16 GB of VRAM is more than sufficient for Downfall at any resolution, given the game's 2016 release date and the fact that even 4K Ultra does not appear to cause memory-related stuttering in the measured data. The 716.8 GB/s memory bandwidth provides ample throughput for texture streaming and geometry at 4K, and the 256-bit bus width is a balanced design for this workload. The GPU's percentile ranking of 86 against all GPUs places it in the 86th percentile, and its nearest rivals show tight competition: the RTX 4080 SUPER scores 54,209 (0.1% higher), the AMD Radeon Pro W5700X scores 54,828 (1.1% higher), the AMD Radeon RX 6750 GRE 12 GB scores 55,698 (2.6% higher), and the AMD Radeon 8060S scores 55,757 (2.7% higher). These delta percentages are small, indicating that the RTX 4080 remains competitive with newer and more specialized parts, even as the GPU is end-of-life per its production status.

The RTX 4080's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 API compatibility ensure it can handle Downfall's rendering features, though the game's age means it likely does not exploit ray tracing or DLSS to the fullest. The GPU's 320 W TDP and triple-slot cooler design indicate a high-power part that requires robust cooling, but the measured FPS figures show the card sustaining high clocks without thermal throttling affecting averages.

How This Combo Ranks

The AMD Ryzen 9 9950X3D + NVIDIA GeForce RTX 4080 combination ranks 230 out of 3,716 tested combos in Downfall, placing it in the top 6.2% of all configurations. This is a strong result, but it also reveals that there are 229 faster combos in the database, likely featuring higher-end GPUs such as the RTX 4090 or newer flagship cards. The combo's rank is consistent with the individual component percentiles: the CPU sits in the 95th percentile and the GPU in the 86th percentile, so the overall ranking reflects the GPU being the slightly weaker link in this pairing.

Given that the CPU's nearest rivals are all within 0.4% of its average benchmark score, the choice of processor likely has minimal impact on Downfall performance. The GPU, however, has more variance in its competitive set, with rivals ranging from 0.1% higher to 2.7% higher in average score. This suggests that swapping the RTX 4080 for a faster GPU would yield noticeable gains in Downfall, particularly at 4K where the GPU is the clear bottleneck. The combo's rank of 230 out of 3,716 means that the vast majority of tested configurations are slower, and the data indicates that this pairing is well-suited for high-refresh-rate gaming at 1440p and smooth 4K gameplay at High settings or below.

Measured FPS Breakdown

At 1920x1080, the combination delivers exceptional frame rates across all presets. Low settings produce 400 FPS average, which is the highest measured result in the entire dataset. Medium settings yield 327 FPS with a minimum of 278 FPS and maximum of 376 FPS, showing tight frame pacing. High settings drop to 268 FPS, while Ultra settings still manage 168 FPS. These numbers indicate that at 1080p, the system is heavily CPU-bound at Low and Medium settings, with the GPU becoming more relevant at High and Ultra.

At 2560x1440, the frame rates remain high but show the expected scaling. Low settings deliver 285 FPS, Medium produces 233 FPS with a minimum of 198 FPS and maximum of 268 FPS, High hits 191 FPS, and Ultra reaches 120 FPS. The 1440p results show that the RTX 4080 is still capable of driving high refresh rates on most presets, with only Ultra falling below the 144 Hz threshold that many high-end monitors target. The gap between Medium and High at 1440p is 18.0%, and between High and Ultra it is 37.2%, matching the pattern seen at 4K.

At 3840x2160, the GPU's limits become apparent. Low settings produce 178 FPS, which is still very playable on a 144 Hz 4K display. Medium settings yield 145 FPS with a minimum of 123 FPS and maximum of 167 FPS, indicating that even the minimum frame rate stays above 120 FPS. High settings drop to 119 FPS, which is just below the 120 Hz threshold but still smooth on most displays. Ultra settings fall to 74 FPS, which is the only measured result below 100 FPS in the entire dataset. The 4K Ultra minimum FPS is not provided, but the average of 74 FPS suggests that this preset should be avoided on 120 Hz or 144 Hz 4K displays.

Settings Recommendations

The measured data shows a clear hierarchy of performance across the four presets, and the optimal choice depends on the user's display and frame rate target. For 1080p gaming, all presets deliver well above 144 FPS, with Low at 400 FPS, Medium at 327 FPS, High at 268 FPS, and Ultra at 168 FPS. Even the Ultra preset at 1080p exceeds the refresh rate of most high-end monitors, so users can safely select Ultra for maximum visual fidelity without sacrificing smoothness.

At 1440p, the High preset's 191 FPS average is ideal for 144 Hz or 165 Hz displays, while Ultra at 120 FPS is sufficient for 120 Hz panels but falls short of 144 Hz. Medium at 233 FPS offers a comfortable margin above 144 Hz, and Low at 285 FPS is overkill for any current display. For users with 1440p 144 Hz monitors, the High preset provides the best balance of visual quality and frame rate, while those with 120 Hz panels can enjoy Ultra without issue.

At 4K, the recommendations shift more conservatively. The Medium preset's 145 FPS average with a 123 FPS minimum is the sweet spot for 120 Hz displays, offering smooth gameplay with moderate settings. The High preset at 119 FPS is suitable for 60 Hz or 120 Hz displays, though the average falls just below the 120 FPS mark. The Ultra preset at 74 FPS is best reserved for 60 Hz displays, where it will still look smooth, but it cannot drive high-refresh-rate panels effectively. The Low preset at 178 FPS provides the highest frame rates at 4K but sacrifices visual quality that the RTX 4080 is capable of delivering at Medium or High.

The most balanced recommendation across all resolutions is the High preset, which delivers 268 FPS at 1080p, 191 FPS at 1440p, and 119 FPS at 4K. This preset offers a consistent experience where the frame rate scales predictably with resolution, and it avoids the steep performance cost of Ultra settings. For users prioritizing visual quality over frame rate, Ultra at 1440p (120 FPS) is a viable choice, while 4K Ultra should be avoided unless the user is content with 74 FPS average. The Medium preset is the safest option for 4K gaming, as it maintains a minimum FPS above 120 and provides a comfortable margin over the High and Ultra presets' lower averages.
