Downfall

The AMD Ryzen 9 9900X3D paired with the AMD Radeon RX 7900 XT delivers a comprehensive performance profile in Downfall, a horror title from 2016. The data shows a system capable of extreme frame rates at lower resolutions, while revealing the expected scaling behavior as graphical load increases. This analysis breaks down the measured FPS across resolutions and settings, examines the roles of the CPU and GPU, and provides actionable settings recommendations based strictly on the benchmark data.

Resolution Scaling

The measured FPS data reveals a clear and predictable scaling pattern as resolution increases from 1920x1080 to 3840x2160. At the High settings preset, the average frame rate drops from 226 FPS at 1080p to 161 FPS at 1440p, and finally to 100 FPS at 4K. This represents a significant performance reduction, with the 4K figure being less than half of the 1080p result. This steep decline indicates that the rendering workload is scaling heavily with pixel count, which is typical for a GPU-bound scenario at higher resolutions.

Examining the Low settings preset shows an even more dramatic drop. The system achieves 337 FPS at 1080p, which falls to 240 FPS at 1440p, and then down to 150 FPS at 4K. The percentage drop from 1080p to 4K is substantial, highlighting that even at the lowest graphical fidelity, the resolution increase places a massive burden on the rendering pipeline. The gap between 1080p and 1440p results is also notable, suggesting that the transition to a higher pixel count has a compounding effect on frame times.

The scaling behavior points to the GPU as the primary limiting component at 4K resolution. The RX 7900 XT, while powerful, must render over four times the pixels at 4K compared to 1080p, and the data shows this workload reduces frame rates by more than half in most settings. Conversely, the relatively small performance gap between some 1080p and 1440p results, particularly at Low settings where the difference is 337 FPS versus 240 FPS, suggests that the CPU is capable of feeding the GPU effectively at these lower resolutions, and the bottleneck shifts almost entirely to the graphics card as resolution climbs.

GPU Role

The AMD Radeon RX 7900 XT is a substantial piece of hardware, built on the RDNA 3.0 architecture with the Navi 31 chip. Its specifications include 20 GB of GDDR6 memory on a 320-bit bus, providing a memory bandwidth of 800.0 GB/s. This large memory pool and high bandwidth are critical for handling the texture and geometry data at 4K resolution, where the measured FPS drops to 63 on the Ultra preset. The GPU’s boost clock is rated at 2394 MHz, with a game clock of 2025 MHz, and it features 5376 shading units, 336 TMUs, and 192 ROPs.

In the context of Downfall, the GPU's role is evident in the resolution scaling. The benchmark results show that at 1080p, even the Ultra preset achieves 141 FPS, which is a high frame rate, but at 4K, the Ultra preset plummets to 63 FPS. This indicates that the card’s raw compute power, rated at 51.48 TFLOPS FP32, is sufficient for high-refresh-rate gaming at lower resolutions but is challenged by the demands of 4K Ultra settings. The 63 FPS average at 4K Ultra is the lowest recorded in the entire dataset, demonstrating that this specific combination of resolution and settings pushes the GPU to its limits.

The GPU’s benchmark scores also provide context. Its Passmark G3D score is 29009, and its percentile versus all GPUs is 55, placing it in the mid-upper tier of graphics cards. Interestingly, its nearest rivals according to the data include the AMD Radeon 660M, which has a delta of -0.5%, and the NVIDIA RTX A2000 Mobile, also at -0.5%. This comparison is based on average benchmark scores, not gaming FPS, but it suggests that the RX 7900 XT's synthetic performance is closely matched by these other cards, even though their real-world gaming capabilities are likely very different. The GPU's raw data, such as its 459.6 GPixel/s pixel rate and 804.4 GTexel/s texture rate, supports its strong showing in the measured FPS at 1440p, where it maintains over 100 FPS even on the Ultra preset.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture (Granite Ridge). It operates with a base clock of 4.40 GHz and a boost clock of 5.50 GHz, and its 128 MB of L3 cache is a defining feature. This processor is clearly not a bottleneck in Downfall at any of the tested resolutions. The evidence for this is the extremely high frame rates achieved at 1080p, where the CPU’s ability to process game logic and draw calls is most critical.

At 1080p Low settings, the system achieves 337 FPS. This high frame rate indicates that the CPU is capable of feeding the GPU with enough data to maintain a very high output. Even at 1080p Ultra, the system manages 141 FPS, which is still a very playable and high frame rate. The CPU’s strong performance is corroborated by its benchmark scores, including a Cinebench R23 multicore score of 47737 and a single-core score of 6739. Its Geekbench multicore score is 22884, and its Passmark multithread score is 56154.

The CPU's role becomes less demanding as resolution increases, as the bottleneck shifts to the GPU. However, the data shows no signs of CPU limitation even at 4K, where the average FPS is 100 on High settings. This suggests that the 9900X3D has ample headroom for this title. Its percentile versus all CPUs is 91, indicating it outperforms the vast majority of processors. Its nearest rival, the Intel Core Ultra 5 245KF, has a delta of -0.6%, meaning the 9900X3D is essentially tied with it in average benchmark score, but the 9900X3D’s 12 cores and high cache likely provide a specific advantage in gaming workloads like Downfall that can utilize multiple threads.

How This Combo Ranks

The combined performance of the AMD Ryzen 9 9900X3D and AMD Radeon RX 7900 XT places this system at rank 525 out of 2928 tested combos in Downfall. This percentile placement indicates that this configuration outperforms the majority of other CPU-GPU pairings tested in this game. Being in the top 18% of all combos is a strong result, reflecting the high-end nature of both components.

This ranking is consistent with the measured FPS data. The system's ability to maintain over 200 FPS at 1080p Medium and over 160 FPS at 1440p High demonstrates a level of performance that many other combinations would struggle to achieve. The rank of 525 shows that while there are faster combinations, this pairing is firmly in the upper echelon of performance for Downfall. The data suggests that the combination is well-balanced, with the CPU’s strength preventing any bottleneck at lower resolutions, and the GPU’s power providing strong results at higher resolutions. The system does not exhibit any obvious weak points, as the scaling from 1080p to 4K is consistent and predictable, without any anomalous drops that would indicate a driver issue or a component mismatch.

Measured FPS Breakdown

The complete dataset includes 12 measurements, covering three resolutions and four settings presets. For 1920x1080, the results are as follows: Low settings yield an average of 337 FPS, Medium settings average 275 FPS with minimum and maximum values of 234 and 317 FPS respectively, High settings average 226 FPS, and Ultra settings average 141 FPS. These numbers show a clear hierarchy, with each step up in settings costing a significant number of frames.

At 2560x1440, the performance scales down predictably. Low settings average 240 FPS, Medium settings average 197 FPS (with a minimum of 167 and maximum of 226), High settings average 161 FPS, and Ultra settings average 101 FPS. The drop from 1080p to 1440p is roughly 30% across most settings, which is a substantial but expected reduction for a resolution increase of 78% in pixel count.

Finally, at 3840x2160, the system still delivers playable frame rates. Low settings average 150 FPS, Medium settings average 122 FPS (with a minimum of 104 and maximum of 141), High settings average 100 FPS, and Ultra settings average 63 FPS. The 4K Ultra result is the only measurement that falls below the 100 FPS threshold, indicating that this is the most demanding configuration in the test. The data shows that the system is capable of high refresh rate gaming at 1080p and 1440p, and remains capable of smooth 60+ FPS gaming at 4K on all but the highest settings.

Settings Recommendations

Based strictly on the measured FPS values, the optimal settings depend on the user's target resolution and refresh rate. For 1920x1080, all settings presets provide well over 140 FPS, so the choice is between maximizing visual quality and achieving the absolute highest frame rates. The Low preset at 337 FPS is excessive for most displays, and the Ultra preset at 141 FPS is still exceptionally high. The Medium preset, at 275 FPS, offers a good balance, but the data suggests that High settings at 226 FPS provides a superior visual experience without a meaningful drop in smoothness for most users.

At 2560x1440, the Ultra preset drops to 101 FPS, which is still very smooth, but the High preset at 161 FPS provides a better margin for maintaining a high refresh rate. The Medium preset at 197 FPS is also a strong choice. For users with a 144 Hz monitor, the High preset is recommended as it offers a significant visual upgrade over Medium while still being well above the refresh rate. The Low preset at 240 FPS is only advisable for competitive play where every frame matters.

At 3840x2160, the situation changes. The Ultra preset averages 63 FPS, which is right at the edge of standard 60 Hz displays, but it may experience occasional dips. The High preset at 100 FPS is a much safer choice for a smooth experience on a 60 Hz or even a 120 Hz display. The Medium preset at 122 FPS is also excellent. For 4K gaming, the High preset is the recommended choice, as it provides a large visual improvement over Medium while maintaining a frame rate that is nearly double the Ultra preset’s performance. The data strongly suggests that Ultra settings at 4K are not worth the significant performance penalty, as the difference in visual fidelity is often negligible compared to the 37% drop in frame rate from High to Ultra.
