Downfall

The AMD Ryzen 7 5800X paired with the AMD Radeon RX 6650 XT delivers a measured performance profile in Downfall, a 2016 horror title. The data set includes average FPS at three resolutions and four quality presets, along with a combo rank of 1081 out of 1741 tested combinations. This analysis breaks down how the pair scales with resolution, which settings are playable, and what the CPU contributes to the results.

Resolution Scaling

The measured FPS values show a consistent drop as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average FPS falls from 197 at 1080p to 144 at 1440p (a 27% reduction) and then to 90.5 at 4K (a 54% reduction from 1080p). Medium settings follow the same pattern: 163 at 1080p, 118.9 at 1440p (27% lower), and 75.1 at 4K (54% lower). High settings drop from 134 at 1080p to 92.6 at 1440p (31% lower) and 58.4 at 4K (56% lower). Ultra settings go from 83 at 1080p to 62 at 1440p (25% lower) and 37 at 4K (55% lower). The near-uniform percentage drops across all presets indicate that the GPU is the primary limiting component as pixel count rises. The CPU’s high single-thread performance—Cinebench R23 single-core score of 3327—and its 8-core, 16-thread configuration are sufficient to avoid bottlenecking at lower resolutions, as evidenced by the 197 FPS ceiling at 1080p Low. The consistent scaling suggests that the RX 6650 XT’s rendering throughput, with its 2048 shading units and 280.3 GB/s memory bandwidth, is the factor that determines frame rates when resolution increases. At 4K Ultra, the average FPS drops to 37, which is below the 60 FPS threshold commonly considered playable, while 1080p Ultra remains at 83 FPS. This reinforces that the GPU is the limiting component, not the CPU.

Settings Recommendations

The measured rows provide clear guidance for each resolution. At 1920x1080, all presets are playable, with Ultra delivering 83 FPS, High 134 FPS, Medium 163 FPS, and Low 197 FPS. For a horror game where visual atmosphere matters, Ultra is the best choice because it maintains a comfortable frame rate while offering the highest quality. At 2560x1440, Ultra yields 62 FPS, which is just above the 60 FPS line, but High provides 92.6 FPS—a smoother experience with only a modest visual sacrifice. Medium at 118.9 FPS is also viable, but High strikes the best balance between fidelity and fluidity. At 3840x2160, Ultra is not recommended because 37 FPS is too low for a responsive experience. High reaches 58.4 FPS, close to 60 but not quite there, while Medium delivers 75.1 FPS, which is comfortable. Low at 4K gives 90.5 FPS but sacrifices significant visual quality. Therefore, the optimal presets are 1080p Ultra, 1440p High, and 4K Medium, based on the measured average FPS values.

The data set does not include minimum or maximum FPS values, so the average figures represent the only measured performance indicators. The progression from Low to Ultra at each resolution shows a clear trade-off between visual quality and frame rate, with the largest gap occurring at 4K where Ultra is 53.5 FPS lower than Low.

How This Combo Ranks

The combo ranks 1081 out of 1741 tested combinations in Downfall, placing it in the lower half of the field. This is notable because the individual components have strong benchmark standings: the CPU sits in the 84th percentile among all CPUs, and the GPU in the 72nd percentile among all GPUs. The CPU’s average benchmark score is 27606, with nearest rivals including the AMD Ryzen 7 5800 (27535, 0.3% lower) and the Intel Core i5-12600KF (27827, 0.8% higher). The GPU’s average benchmark score is 29024, with the AMD Radeon RX 6800M at 29011 (0% delta) and the Intel Arc A370M at 29175 (0.5% higher). Despite these solid component-level scores, the combo’s in-game rank is lower than either percentile would suggest. This indicates that Downfall’s performance is not solely determined by raw component strength; other factors such as driver optimization, memory configuration, or game-specific bottlenecks may play a role. The rank of 1081 means that 1080 combos achieve higher average FPS in this title, while 660 combos perform worse. For a mid-range GPU paired with a high-end CPU, this result is plausible, as the GPU is likely the limiting factor in most scenarios.

CPU Role

The AMD Ryzen 7 5800X is a Zen 3 architecture processor with 8 cores and 16 threads, base clock of 3.80 GHz, and boost clock of 4.70 GHz. It has a 32 MB L3 cache and supports DDR4 memory with a dual-channel bus. In Downfall, the CPU’s role is to feed the GPU with draw calls and game logic. The measured FPS at 1080p Low reaches 197, which is high enough to indicate that the CPU is not a bottleneck at that resolution. The single-thread performance, reflected in a Cinebench R23 single-core score of 3327, is strong for a 2016 title that likely relies on a few threads. The multi-thread score of 23571 shows ample headroom for any background tasks. The CPU’s nearest rivals in benchmark scores are all within 0.8% of its average score, meaning its performance is competitive with other mid-range and high-end processors. The 8-core, 16-thread configuration is more than sufficient for a horror game of this era, and the boost clock of 4.70 GHz helps maintain high frame rates even when the GPU is under load. The L3 cache of 32 MB reduces memory latency, which can benefit game performance. Overall, the CPU provides a solid foundation for the RX 6650 XT, and the data shows that the GPU becomes the limiting factor as resolution and settings increase.
