Downfall

# Downfall with AMD Ryzen 7 9700X + AMD Radeon RX 7900 XT

The AMD Ryzen 7 9700X paired with the AMD Radeon RX 7900 XT delivers a formidable 1080p experience in Downfall, with the 8-core Zen 5 processor and RDNA 3.0 flagship GPU combining for triple-digit frame rates across every preset. The combo ranks 362nd out of 1,741 tested configurations, placing it in the top 21% of all systems measured for this horror title. This pairing leverages the CPU's 89th percentile standing among all processors and the GPU's 82nd percentile among all graphics cards, creating a balanced platform that scales predictably as resolution increases.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a GPU-bound workload at higher resolutions, while the CPU demonstrates ample headroom at lower settings. At Ultra settings, the average frame rate drops from 139.7 FPS at 1920x1080 to 102.6 FPS at 2560x1440 — a 26.5% reduction — then falls further to 66 FPS at 3840x2160, representing a 36% decrease from 1440p. This steepening decline indicates the RX 7900 XT becomes the primary bottleneck as pixel count increases, with the 20 GB frame buffer and 800.0 GB/s memory bandwidth absorbing the added pressure.

The Low preset tells a different story. At 1080p, the system produces 337.7 FPS, dropping to 242.2 FPS at 1440p (a 28.3% reduction) and 148.9 FPS at 4K (a 38.5% reduction from 1440p). The percentage drops between resolutions remain similar across presets, suggesting the scaling factor is resolution-driven rather than settings-driven. However, the absolute delta between Low and Ultra at 4K — 82.9 FPS — far exceeds the 198 FPS gap at 1080p, confirming that the GPU's compute resources are the limiting factor once resolution climbs.

Notably, the gap between Medium and High narrows as resolution increases. At 1080p, the difference is 48.9 FPS (273.2 vs. 224.3), while at 4K it shrinks to 21.1 FPS (120.8 vs. 99.7). This compression suggests that at higher resolutions, both presets converge on similar GPU utilization limits, whereas at 1080p the CPU can feed enough frames to expose the settings' computational cost. The Ryzen 7 9700X's 5.50 GHz boost clock and 89.6 GB/s memory bandwidth keep the pipeline fed at lower resolutions, but the RX 7900 XT's 51.48 TFLOPS FP32 throughput becomes the ceiling at 4K.

GPU Role

The Radeon RX 7900 XT's specifications directly shape Downfall's performance envelope. With 20 GB of GDDR6 memory on a 320-bit bus, the card delivers 800.0 GB/s bandwidth, which proves sufficient for even the most demanding 4K Ultra workloads. The GPU's 84 ray accelerators and 192 ROPs handle the horror title's lighting and shadow effects, while the 5376 shading units process the game's texture work. Clock speeds peak at 2394 MHz boost, with a game clock of 2025 MHz, providing the raw throughput that drives the measured results.

The GPU's 82nd percentile ranking among all graphics cards places it near the NVIDIA GeForce RTX 5080 Mobile in average benchmark score, with a delta of 0% — a statistical tie. The RX 7900 XT also edges out the NVIDIA CMP 70HX by 0.3% and trails the GeForce MX570 by 0.4%, though these synthetic benchmarks only partially predict gaming behavior. In Downfall specifically, the card's 16,828 Passmark GPU compute score and 29,009 Passmark G3D score indicate strong general-purpose and 3D rendering capabilities that translate to the measured frame rates.

The 300 W TDP and dual-slot design with 2x 8-pin power connectors suggest the card maintains consistent clocks under sustained load, which is critical for maintaining the 99.7 FPS average at 4K High. The 5 nm process node and 57,700 million transistors on a 529 mm² die allow for high density and efficiency, though the card's end-of-life production status means no future firmware optimizations are anticipated. The 12 Ultimate DirectX support and Vulkan 1.4 API compatibility ensure modern rendering features are accessible, though Downfall's 2016 release date means it likely relies on older DirectX 11 paths.

Settings Recommendations

The measured data indicates that High settings at 2560x1440 offer the optimal balance of visual fidelity and performance, delivering 162.8 FPS average — well above the 60 FPS threshold for smooth gameplay. At 4K, High produces 99.7 FPS, which remains playable on high-refresh displays, but the jump to Ultra costs 33.7 FPS (from 99.7 to 66), a 33.8% penalty that may not justify the visual gains in a horror title where atmosphere matters more than fine detail.

For competitive or high-refresh-rate play, the Low preset at 1080p delivers 337.7 FPS, which exceeds the refresh rate of most monitors and provides maximum responsiveness. The Medium preset at 1440p offers 195.2 FPS, a middle ground that maintains high frame rates while improving visual quality over Low. The Ultra preset at any resolution above 1080p drops below 140 FPS, with the 4K Ultra result of 66 FPS representing the only measured configuration that approaches the 60 FPS minimum for comfortable play.

The data suggests that the Ryzen 7 9700X can push well beyond 240 FPS at 1080p Low, meaning the CPU is not the limiting factor in most scenarios. The GPU's 20 GB memory capacity ensures no texture pop-in or streaming stutter at any resolution, making the High preset the recommended choice for users prioritizing frame rate consistency. At 4K, Medium (120.8 FPS) provides a 21.1 FPS advantage over High while likely preserving the majority of visual enhancements in a game from 2016.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all presets. Low averages 337.7 FPS, Medium averages 273.2 FPS, High averages 224.3 FPS, and Ultra averages 139.7 FPS. The progression from Low to Ultra represents a 58.6% reduction in frame rate, with each successive preset tier costing approximately 50-60 FPS. The 198 FPS spread between Low and Ultra at 1080p highlights the GPU's ability to render frames faster than the CPU can feed them at lower settings, though the Ryzen 7 9700X's 3DMark single-thread score of 1,280 and Passmark single-thread score of 4,654 suggest it can sustain these rates.

At 2560x1440, the frame rates remain high but show increased GPU pressure. Low averages 242.2 FPS, Medium averages 195.2 FPS, High averages 162.8 FPS, and Ultra averages 102.6 FPS. The gap between Low and Ultra narrows to 139.6 FPS, and the percentage difference between presets shrinks slightly, indicating the GPU's render time per frame is growing. The 4K results show the most pronounced GPU limitation: Low averages 148.9 FPS, Medium averages 120.8 FPS, High averages 99.7 FPS, and Ultra averages 66 FPS. The Ultra preset at 4K is the only measured configuration that falls below 100 FPS, and its 66 FPS average represents a 56.2% reduction from the 1080p Ultra result.

The 1080p to 1440p scaling at each preset is consistent, with frame rates dropping by roughly 28-35%. The 1440p to 4K scaling shows a steeper decline, with frame rates dropping by 38-41%. This non-linear degradation pattern is characteristic of a GPU that approaches its memory bandwidth limit, though the 800.0 GB/s figure appears sufficient for the game's demands given that even 4K Ultra maintains a playable 66 FPS average.

How This Combo Ranks

The combination of AMD Ryzen 7 9700X and AMD Radeon RX 7900 XT ranks 362nd out of 1,741 tested combos in Downfall, placing it in the 79th percentile of all systems measured. This rank reflects the strong individual performance of both components: the CPU's average benchmark score of 36,029 places it in the 89th percentile of all processors, while the GPU's average benchmark score of 38,358 places it in the 82nd percentile of all graphics cards. The slight discrepancy between component percentiles and the overall combo rank suggests that the game's engine favors certain hardware combinations, though the pairing remains competitive.

The CPU's nearest rivals include the Intel Core i5-14500HX with an average score of 35,940 (0.2% ahead), the AMD Ryzen 7 PRO 5845 with 35,802 (0.6% behind), the Intel Core Ultra 9 185H with 36,165 (0.4% behind), and the Intel Core Ultra 5 225H with 36,328 (0.8% behind). These deltas are negligible, indicating the Ryzen 7 9700X performs on par with a range of mobile and desktop processors in synthetic benchmarks, though its 8-core, 16-thread configuration with 32 MB of shared L3 cache provides strong multi-threaded performance for games that utilize multiple cores.

The GPU's nearest rivals show a similar clustering: the NVIDIA GeForce RTX 5080 Mobile matches the RX 7900 XT's average score exactly (0% delta), the NVIDIA CMP 70HX trails by 0.3%, the NVIDIA GeForce MX570 leads by 0.4%, and the NVIDIA GeForce RTX 4080 Mobile trails by 0.6%. These margins are within measurement noise, but the RX 7900 XT's 20 GB memory capacity and 320-bit bus width provide an advantage in memory-intensive scenarios that synthetic benchmarks may not fully capture. In Downfall, the measured frame rates confirm that this combo delivers a high-refresh-rate experience at 1080p and 1440p, with 4K remaining viable on High settings or below.
