Downfall

The AMD Ryzen 7 7800X3D and AMD Radeon RX 6800 XT combination delivers a strong showing in Downfall, a 2016 horror title. The pairing of an 8-core, 16-thread Zen 4 processor with a high-end RDNA 2 graphics card produces frame rates that are consistently high across all tested resolutions, though the relationship between the two components shifts as the workload changes. The data indicates a system that is adaptable, offering both extremely high refresh rate potential at 1080p and solid 4K performance.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 7800X3D is built on the Zen 4 architecture and features 8 cores and 16 threads. Its base clock is 4.20 GHz, with a boost clock of 5.00 GHz. A key characteristic is its large 96 MB of shared L3 cache, which is often beneficial in gaming scenarios by reducing memory latency. The CPU's processing power is reflected in its benchmark scores, such as a Cinebench R23 multi-core score of 29149 and a single-core score of 4115. In Geekbench, it achieves 15101 multi-core and 2725 single-core. These synthetic results place the processor in the 87th percentile among all CPUs tested.

In the context of Downfall, the processor's capability is most evident at lower resolutions. The measured data shows that at 1920x1080 with Low settings, the system produces an average of 287.2 FPS. This high frame rate suggests that the CPU is capable of feeding the GPU with enough data to avoid becoming the primary constraint. The 7800X3D's high single-thread performance, evidenced by its 3dmark_single_thread score of 959, is likely a contributing factor to this headroom. Compared to its nearest rivals, the processor's average benchmark score of 31580 is nearly identical to the Intel Core i7-12700F, which has an average score of 31543, a negligible delta of 0.1%. This indicates that while the CPU is powerful, its performance ceiling is not uniquely superior to other top-tier options in synthetic tests, yet its cache configuration may still give it an edge in specific gaming workloads.

How This Combo Ranks

Within the database, this specific combination of the Ryzen 7 7800X3D and the Radeon RX 6800 XT achieves a combo rank of 609 out of 1741 tested combos in Downfall. This places the pairing in the upper third of all systems tested, indicating a well-balanced configuration that outperforms the majority of other hardware pairings. The rank reflects the combined capabilities of both the CPU and GPU. The CPU's strong multi-threaded and single-threaded performance, combined with the GPU's substantial compute power, results in a system that handles the game's demands effectively across a wide range of settings. The fact that it is not ranked higher suggests that other combinations with even more powerful components exist, but this pairing clearly represents a high-performance tier. The data shows this is a capable setup, sitting comfortably ahead of the median system in the database for this title.

Resolution Scaling

The performance scaling from 1080p to 4K clearly illustrates the shifting bottleneck between the CPU and GPU. At 1920x1080 with High settings, the average frame rate is 191.9 FPS. Moving to 2560x1440, the average drops to 138 FPS, a reduction of 53.9 FPS. This significant drop indicates that the GPU is beginning to work harder. At 3840x2160, the average further drops to 84 FPS, a decrease of 54 FPS from the 1440p result. This pattern continues across all settings presets. For instance, with Low settings, the frame rate falls from 287.2 FPS at 1080p to 205.1 FPS at 1440p, and then to 129.9 FPS at 4K.

This scaling behavior is typical of a system where the CPU has enough headroom at lower resolutions, and the GPU becomes the limiting factor as the resolution increases. The frame rate dips are substantial at each step, particularly between 1080p and 1440p, suggesting that the RX 6800 XT is being utilized more heavily to render the additional pixels. At 4K, the workload is almost entirely on the GPU. The data shows that while the CPU is strong enough to push very high frame rates at 1080p, the overall system performance in Downfall is ultimately governed by the graphics card's rendering capabilities at higher resolutions.

Measured FPS Breakdown

The measured FPS data provides a detailed look at performance across different resolution and settings combinations.

1920x1080: At this resolution, the system excels. With Low settings, the average FPS is 287.2. Moving to Medium settings yields 235.4 FPS. High settings produce 191.9 FPS. The most demanding preset, Ultra, still delivers a very high average of 123.8 FPS. These numbers indicate that for 1080p gaming, this combo is more than sufficient to drive high-refresh-rate monitors, even with the most demanding settings.

2560x1440: At 1440p, performance remains strong. Low settings average 205.1 FPS, while Medium settings average 169.8 FPS. High settings produce 138 FPS. The Ultra preset delivers an average of 89.8 FPS, which is still comfortably above the 60 FPS threshold for smooth gameplay. This resolution appears to be the sweet spot for balancing high visual quality with high frame rates.

3840x2160: At 4K, the GPU workload increases considerably. Low settings achieve an average of 129.9 FPS, which is impressive. Medium settings drop to 103.1 FPS. High settings yield 84 FPS, which remains playable. However, the Ultra preset brings the average down to 54.9 FPS. This is the only configuration in the measured set that falls below the 60 FPS mark, indicating that while the system is capable of 4K gaming, users will need to adjust settings from the maximum preset to maintain a consistently smooth experience.

GPU Role

The AMD Radeon RX 6800 XT is the primary driver of performance in Downfall, particularly at higher resolutions. It is built on the RDNA 2.0 architecture and features 16 GB of GDDR6 memory on a 256-bit bus, providing a memory bandwidth of 512.0 GB/s. The GPU's clock speeds are 1825 MHz base, 2015 MHz game, and 2250 MHz boost. Its compute power is substantial, with 4608 shading units and a FP32 performance of 20.74 TFLOPS. These specifications place the GPU in the 87th percentile of all GPUs, with an average benchmark score of 49982. Its closest rival, the Intel Arc A550M, has an average score of 49737, a delta of just 0.5%, showing they are closely matched in overall compute.

The impact of this GPU is clear in the measured frames. At 4K Ultra, the GPU is heavily tasked, resulting in 54.9 FPS. When the settings are lowered to High at 4K, the frame rate jumps to 84 FPS, demonstrating the GPU's ability to handle a lighter load much more efficiently. The 16 GB of VRAM is a considerable asset for a game like Downfall, ensuring that texture memory is not a limiting factor at any of the tested settings. The performance difference between Medium and High settings at 4K (103.1 FPS vs 84 FPS) shows that the GPU has a significant amount of headroom when not pushed to its absolute limits.

Settings Recommendations

Based on the measured data, the optimal settings depend on the user's resolution and refresh rate target.

For 1920x1080, the Ultra preset is the clear recommendation. With an average of 123.8 FPS, it provides an excellent balance of visual fidelity and performance. There is no reason to lower the settings, as even the most demanding preset delivers a very high frame rate.

For 2560x1440, the High preset is the best choice. It delivers an average of 138 FPS, which is ideal for high-refresh-rate monitors. While the Ultra preset also performs well at 89.8 FPS, the High preset offers a significant frame rate advantage with a likely minimal visual difference. This combination provides the best experience for most 1440p displays.

For 3840x2160, the High preset is the recommended starting point. It offers an average of 84 FPS, which provides smooth and responsive gameplay. The Ultra preset's 54.9 FPS may be acceptable for some, but the 29 FPS improvement from dropping to High settings is substantial and makes for a much more fluid experience. If a higher frame rate is desired, even the Medium preset at 103.1 FPS is a viable option, but High offers the best balance of quality and performance.
