Downfall

Downfall, a horror title from 2016, presents a fascinating case study in system scaling with the AMD Ryzen 7 9850X3D and NVIDIA GeForce RTX 4080 SUPER. The measured data reveals a configuration that is overwhelmingly GPU-bound at higher resolutions but hints at potential CPU limitations at the extreme low end of the settings spectrum. This analysis breaks down the measured FPS across resolutions and settings, interpreting what the numbers imply about the roles of each component in this specific title.

Resolution Scaling

The progression from 1080p to 4K with this hardware combination shows a predictable and steep decline in frame rates, which is the classic signature of a GPU-bound workload at higher resolutions. At High settings, the average frame rate drops from 267 FPS at 1920x1080 to 190 FPS at 2560x1440, a reduction of 77 FPS. Moving further up to 3840x2160, the average falls to 118 FPS, a substantial 149 FPS drop from the 1080p figure. This scaling pattern is consistent across all settings presets, indicating that the rendering resolution is the primary factor limiting performance.

The data suggests that at 1080p and 1440p, the system has enough headroom to push well beyond the refresh rates of most standard monitors. However, the 4K results, particularly at Ultra settings where the average FPS falls to 74, show the RTX 4080 SUPER being pushed to its limits. The gap between Low and Ultra settings widens as resolution decreases. At 4K, the delta between Low (177 FPS) and Ultra (74 FPS) is 103 FPS. At 1440p, this delta expands to 165 FPS (284 FPS vs 119 FPS). At 1080p, the delta is even more pronounced at 230 FPS (397 FPS vs 167 FPS). This increasing spread at lower resolutions strongly implies that the CPU is capable of feeding the GPU far more frames than the GPU can render at higher settings, making the GPU the definitive bottleneck in those scenarios.

The question this data raises is whether the Ryzen 7 9850X3D is ever the limiting factor. The 1080p Low result of 397 FPS is remarkable and suggests the CPU is still not fully saturated. If the CPU were the bottleneck, we would expect to see a plateau in frame rates regardless of resolution or settings. The fact that the frame rate nearly doubles from 4K Ultra (74 FPS) to 1080p Low (397 FPS) indicates that the GPU is still the primary constraint even at the lowest tested settings, though the gap between the 1440p Low (284 FPS) and 1080p Low (397 FPS) suggests a diminishing return that could hint at an approaching CPU ceiling at very high frame rates.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the dominant component in this configuration for Downfall. Its performance characteristics, including a boost clock of 2550 MHz and a substantial 16 GB of GDDR6X memory on a 256-bit bus, provide the bandwidth and compute throughput necessary for the high frame rates observed. The memory bandwidth of 736.3 GB/s is a critical asset, particularly at 4K resolution where the demand for texture and geometry data is immense. The data shows the GPU is the primary driver of performance scaling, as evidenced by the significant FPS drops when resolution increases.

The 16 GB VRAM capacity is not a limiting factor in any of the measured scenarios, as the game is from 2016 and would not require such a large framebuffer. The GPU's 80 RT cores and 320 Tensor cores, while powerful, are unlikely to be heavily utilized in this title unless specific ray tracing or DLSS features are enabled, which are not indicated in the measured data. The core clock behavior, with a base of 2295 MHz and a boost of 2550 MHz, is typical for this class of card and contributes to its raw rasterization performance. The benchmark scores, such as a 3DMark Steel Nomad DX12 score of 6600 and a Passmark G3D score of 34245, place it in the 86th percentile of all GPUs, confirming its high-end status.

The data shows that the RTX 4080 SUPER's performance is the deciding factor between a playable and a highly demanding experience. At 4K Ultra, the 74 FPS average is the lowest recorded, but it is still respectable for a horror title. The GPU's ability to deliver 118 FPS at 4K High suggests that it is well-suited for high-refresh-rate 4K gaming in this older title. Its position relative to its nearest rivals, such as the RTX 4080 which has a negligible average score delta of -0.1%, shows that it is a refined version of an already powerful card.

FAQ

Measured FPS Breakdown

The measured data provides a complete matrix of performance across three resolutions and four quality presets. At 1920x1080, the system demonstrates extreme performance. The Low preset achieves an average of 397 FPS, while the Medium preset averages 325 FPS with a minimum of 276 FPS and a maximum of 374 FPS. The High preset averages 267 FPS, and the Ultra preset averages 167 FPS. These numbers indicate that at 1080p, the system is almost always limited by the CPU's ability to issue draw calls, though the GPU is still the main factor at Ultra.

Moving to 2560x1440, the frame rates remain very high. The Low preset averages 284 FPS, the Medium preset averages 232 FPS with a minimum of 197 FPS and a maximum of 267 FPS. High settings bring the average down to 190 FPS, and Ultra settings reduce it further to 119 FPS. At this resolution, the GPU begins to assert its dominance more clearly, with the scaling from Low to Ultra showing a 165 FPS drop.

At 3840x2160, the RTX 4080 SUPER is thoroughly tested. The Low preset averages 177 FPS, which is still very high. The Medium preset averages 144 FPS with a minimum of 123 FPS and a maximum of 166 FPS. The High preset averages 118 FPS, and the Ultra preset averages 74 FPS. This shows a clear and consistent scaling pattern where the GPU's rendering load is the primary determinant of performance. The minimum FPS data points, such as 123 FPS at 4K Medium and 197 FPS at 1440p Medium, provide insight into frame time consistency, suggesting that the system maintains smooth performance without significant stutters.

How This Combo Ranks

The AMD Ryzen 7 9850X3D and RTX 4080 SUPER combination achieves a rank of 194 out of 2928 tested combos in Downfall. This places the system in the top 6.6% of all configurations tested for this game. This is a strong ranking, reflecting the high-end nature of both components. The CPU itself is in the 92nd percentile of all CPUs based on its average benchmark score, and the GPU is in the 86th percentile of all GPUs, so the pairing of two high-percentile parts yields a top-tier result.

The ranking implies that there are 193 other combinations that perform better, likely including more powerful GPUs like the RTX 4090 or newer generation cards. The data shows that while the CPU is powerful, its performance in this game is secondary to the GPU. The substantial FPS differences between settings and resolutions are the primary drivers of this ranking. A combination with a faster GPU would likely see a better rank, especially at 4K Ultra settings where the RTX 4080 SUPER's 74 FPS average is a limiting factor. The near-identical performance of the RTX 4080 SUPER to the RTX 4080 (deltaPct -0.1%) suggests that this ranking is representative of what users with either card would experience.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1920x1080, the High preset provides an excellent 267 FPS average, which is more than sufficient for any high-refresh-rate monitor. The Ultra preset, at 167 FPS, is also a viable option for those who prioritize visual fidelity, as it still offers a very high frame rate.

For 2560x1440, the High preset is the recommended choice. The 190 FPS average provides a perfect experience for 144 Hz and even 165 Hz monitors, with enough overhead to prevent drops. The Ultra preset, at 119 FPS, is also excellent and would be the best choice for a 120 Hz display, offering a significant visual upgrade over High for a 71 FPS cost. The Medium preset is a good fallback if higher, more consistent frame rates are desired, averaging 232 FPS.

For 3840x2160, the High preset is the clear recommendation. The 118 FPS average is ideal for 120 Hz displays, providing a smooth and immersive experience. The Ultra preset is also playable at 74 FPS, but for a horror game that can have sudden action sequences, the higher frame rate of the High preset is preferable for maintaining smoothness and responsiveness. The Low and Medium presets are not recommended at 4K, as the visual quality loss is significant for a minimal performance gain, with the GPU still being the primary bottleneck.

CPU Role

The AMD Ryzen 7 9850X3D plays a supporting but crucial role in this configuration. With 8 cores and 16 threads based on the Zen 5 architecture, it has more than enough processing power for a 2016 title like Downfall. Its high boost clock of 5.60 GHz and the massive 96 MB of shared L3 cache are key assets for gaming. The benchmark data shows a Cinebench R23 multi-core score of 22807 and a single-core score of 2228, which are strong numbers that place it in the 92nd percentile of all CPUs.

In Downfall, the CPU's role is to feed the GPU with data. The evidence suggests it performs this task admirably. At 1080p Low, the system reaches 397 FPS, a figure that is likely near the game's engine limit or the CPU's maximum throughput. The scaling from 1080p Low to 1440p Low (284 FPS) and then to 4K Low (177 FPS) shows a clear dependence on resolution, which points to the GPU becoming the bottleneck as the pixel count increases. If the CPU were limiting, we would expect the FPS to remain similar across resolutions at the same settings. This is not the case, confirming the GPU is the primary constraint.

The CPU's performance relative to its nearest rivals, such as the Intel Core i9-14900 with a deltaPct of 0.5%, shows it is competitive with the best desktop processors. Its high single-thread performance, evidenced by a Passmark single-thread score of 4704, is critical for games that rely on a few heavily-threaded processes. The data indicates that the CPU is not a bottleneck in this title, providing ample headroom for the RTX 4080 SUPER to operate at its full potential. The 397 FPS at 1080p Low confirms the CPU's ability to handle high frame rate scenarios, ensuring that the GPU is the only limiting factor in the vast majority of gaming situations.
