Downfall

The AMD Ryzen 7 5800XT paired with the AMD Radeon RX 6800 XT delivers a compelling 1080p and 1440p experience in Downfall, but the data reveals a sharp performance cliff when pushing to 4K Ultra. The measured frames per second (FPS) across the twelve tested configurations show a system that is heavily GPU-bound at lower resolutions, yet struggles to maintain playable frame rates at the highest fidelity settings.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a dramatic and telling collapse in frame rates, particularly at the highest settings. At Ultra settings, the average FPS drops from 118.7 at 1080p to 85.7 at 2560x1440, a 27.8% reduction, and then plummets further to 52.1 at 4K, which is a 39.2% drop from the 1440p figure. This steep decline at 4K Ultra suggests that the Radeon RX 6800 XT's 16 GB of GDDR6 memory and its 512.0 GB/s bandwidth are being saturated by the game's most demanding texture and shading workloads.

The scaling pattern at lower settings tells a different story. At Low settings, the FPS only falls from 288.8 at 1080p to 207.5 at 1440p (a 28.1% decrease) and then to 129.1 at 4K (a 37.8% decrease from 1440p). The percentage losses are similar across settings, but the absolute numbers at Low are far higher. This indicates that when the CPU is not the bottleneck, the GPU still scales predictably with resolution, but the frame rates at 1080p Low (288.8) are so high that the Ryzen 7 5800XT's 16 threads are likely the limiting factor, preventing even higher numbers.

The most revealing data point is the 4K Ultra result of 52.1 FPS. This is a 55.9% drop from the 4K Low result of 129.1. This massive gap between Low and Ultra at the same resolution highlights the enormous cost of the game's high-end visual effects. The data implies that Downfall's Ultra preset includes features that are disproportionately heavy on the GPU, making resolution scaling less linear and more punishing at the top end.

GPU Role

The Radeon RX 6800 XT, built on the RDNA 2.0 architecture, is the clear driver of performance in these tests. Its 16 GB of VRAM is a critical asset, as the 4K High result of 88.2 FPS versus the 4K Ultra result of 52.1 FPS suggests that the Ultra preset is likely exceeding the optimal VRAM usage or shader complexity for this card. The GPU's boost clock of 2250 MHz and game clock of 2015 MHz provide the raw compute power, but the data shows that raw clock speed alone doesn't overcome the demands of the Ultra preset.

The GPU's benchmark scores reinforce its position. It holds an 87th percentile ranking among all GPUs and an average benchmark score of 49982. When compared to its nearest rivals, it sits 2.6% ahead of the NVIDIA GeForce RTX 4070 Ti SUPER and 1.9% ahead of the NVIDIA CMP 50HX, but trails the NVIDIA RTX A1000 by 1.7%. This places the RX 6800 XT in a competitive mid-to-high tier, which aligns with the observed FPS figures. The 20.74 TFLOPS of FP32 performance is substantial, yet the 4K Ultra result shows that even this level of compute is insufficient for a locked 60 FPS experience in this particular horror title.

The GPU's memory configuration is also telling. The 256-bit bus width and 512.0 GB/s bandwidth are substantial, but the 288.0 GPixel/s pixel rate and 648.0 GTexel/s texture rate appear to be the limiting factors at 4K Ultra. The data suggests that while the card has enough memory capacity, the speed at which it can process pixels and textures is what causes the frame rate to dip below 60 FPS at the highest settings.

How This Combo Ranks

In the grand scheme of tested hardware combinations for Downfall, this pairing of the Ryzen 7 5800XT and the RX 6800 XT holds a rank of 613 out of 1741 tested combos. This places it in the 64.8th percentile of all combinations, meaning it outperforms roughly two-thirds of the systems tested while being bested by the top third. This rank reflects a balanced pairing where neither component is severely holding back the other in most scenarios.

This ranking is consistent with the individual component standings. The CPU sits in the 86th percentile of all CPUs, while the GPU is in the 87th percentile. The combo rank being lower than either individual percentile suggests that in Downfall specifically, the synergy between this specific CPU and GPU is slightly less effective than their standalone benchmarks would imply. The high 1080p frame rates (288.8 FPS at Low) indicate the CPU can feed the GPU effectively, but the 4K Ultra drop suggests the GPU becomes the sole bottleneck, making the CPU's high percentile irrelevant at that resolution.

The data implies that for a game like Downfall, which appears to be graphically intensive at its highest presets, the combo's rank is more dependent on the GPU's 4K performance than the CPU's multi-threaded capabilities. The 613th rank out of 1741 combos is a solid, above-average result, but it is not a top-tier placement, largely due to the inability to maintain high frame rates at 4K Ultra.

A: Given the high frame rates at 1080p, the CPU is sufficient. Its Cinebench R23 multi-core score of 23794 is strong, but the game's performance scaling from 1080p to 4K suggests that GPU capabilities, such as the 16 GB VRAM and 512.0 GB/s bandwidth, are more critical for determining the final experience.

CPU Role

The AMD Ryzen 7 5800XT, with its 8 cores and 16 threads based on the Zen 3 architecture, provides a robust foundation for gaming. Its boost clock of 4.80 GHz and base clock of 3.80 GHz allow it to keep up with the GPU at most settings. The CPU's benchmark results, including a Cinebench R23 multi-core score of 23794 and a single-core score of 3359, place it in the 86th percentile of all CPUs, with an average benchmark score of 29774.

The data shows that the CPU's role becomes more prominent at lower resolutions. The 1080p Low average of 288.8 FPS is a clear indicator that the CPU is pushing its limits, as this is an exceptionally high frame rate. In comparison, its nearest rival, the AMD Ryzen 7 6800HS, has an average score of 29856, which is only 0.3% higher, showing that the 5800XT is competitive in its class. The CPU's 32 MB of L3 cache and support for DDR4 memory at 51.2 GB/s bandwidth are sufficient for this game, as the bottleneck shifts almost entirely to the GPU at 4K.

The PassMark multi-thread score of 27988 and the 3DMark max threads score of 7680 further confirm that the CPU is not a weak link. At 1080p High, the system achieves 195.1 FPS, which is a 32.4% drop from the Low setting. This drop is more attributable to the GPU working harder on higher-quality textures than to any CPU limitation. The CPU's performance is consistent, allowing the GPU to be the primary determinant of frame rate across all tested resolutions and settings.

Settings Recommendations

For the best balance of visual quality and performance, the High preset at 2560x1440 is the standout choice. The data shows an average of 138.8 FPS, which is well above the 60 FPS threshold and provides a smooth, high-fidelity experience. The High preset at 4K is also viable, with an average of 88.2 FPS, making it a good option for players who prioritize resolution over maximum settings.

The Ultra preset is not recommended for 4K gaming, as the 52.1 FPS average is below the ideal playable range. At 1440p, Ultra delivers 85.7 FPS, which is acceptable but represents a significant 38.2% performance drop compared to High. The Medium preset provides a solid middle ground, with 167.7 FPS at 1440p and 104.6 FPS at 4K, but it does not offer the same visual fidelity as High for a relatively small FPS gain.

The Low preset, while delivering extremely high frame rates (288.8 FPS at 1080p and 129.1 FPS at 4K), sacrifices too much visual quality for a horror game where atmosphere and lighting are crucial. Based on the measured data, the High preset at 1440p is the sweet spot, offering a 63.3% higher frame rate than 4K Ultra while likely providing a similar visual experience in terms of texture detail and effects.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings average 288.8 FPS, Medium averages 234.9 FPS, High averages 195.1 FPS, and Ultra averages 118.7 FPS. The scaling from Low to Ultra represents a 58.9% reduction in performance, with each successive preset costing a significant number of frames.

At 2560x1440, the frame rates remain high but show a steeper decline. Low settings average 207.5 FPS, Medium averages 167.7 FPS, High averages 138.8 FPS, and Ultra averages 85.7 FPS. The drop from High to Ultra is a 38.2% reduction, indicating that the Ultra preset is disproportionately demanding at this resolution.

At 3840x2160, the performance gap widens considerably. Low settings average 129.1 FPS, Medium averages 104.6 FPS, High averages 88.2 FPS, and Ultra averages 52.1 FPS. The 4K Ultra result is the only configuration in the entire dataset that falls below 60 FPS, and it represents a 40.9% drop from the 4K High result of 88.2 FPS. This final data point underscores the extreme cost of combining the highest resolution with the highest settings preset on this hardware.
