Downfall

Downfall, a 2016 horror title, presents a demanding workload that heavily favors the GPU. The pairing of the AMD Ryzen 9 9900X with the AMD Radeon RX 580 produces a combination that is thoroughly constrained by its graphics card, as the data indicates the CPU has ample headroom while the GPU struggles at higher settings. This analysis examines the measured performance data, focusing on how each component contributes to the frame rates across various resolutions and presets.

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

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture, running on the AMD Socket AM5 platform. It operates at a base clock of 4.40 GHz and can boost up to 5.60 GHz, with a 120 W TDP. This desktop chip, released in August 2024, is a high-end part, ranking in the 94th percentile among all CPUs tested. Its synthetic benchmark scores are substantial, including a Cinebench R23 multicore score of 46438 and a single-core score of 6555, alongside a Geekbench multicore score of 19827.

In the context of Downfall, the CPU’s role is largely secondary. The measured frame rates across all tested configurations show a pattern typical of GPU-bound scenarios, where the graphics card is the limiting factor. The Ryzen 9 9900X’s high single-thread performance, evidenced by a 3dmark single-thread score of 1286, ensures that it is not a bottleneck for the game’s logic and draw calls, even at lower resolutions where CPU load typically increases. The processor's average benchmark score of 54450 places it in close competition with its nearest rivals: it is 0.4% behind the AMD Ryzen 9 9900X3D, 0.7% ahead of the Intel Core i7-14700F, and 1.5% behind the Intel Core Ultra 5 245K.

The data suggests that the CPU's capabilities far exceed what Downfall requires. At 1080p Low, the configuration achieves 102.9 FPS, which is the highest frame rate recorded in this dataset. This is not due to the CPU unlocking the GPU’s full potential, but rather because the GPU is less stressed at this setting. The 12 cores and 24 threads are far more than a 2016 horror title would utilize, making the processor's multi-threaded might, such as its Passmark multithread score of 54643, irrelevant to the game's performance. Instead, the CPU’s strong single-core performance ensures a stable baseline, allowing the RX 580 to operate as the sole determinant of frame rate.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 580 is the clear performance limiter in this configuration. This GPU, based on the Polaris 20 chip and GCN 4.0 architecture, features 8 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 256.0 GB/s. Its base clock is 1257 MHz with a boost clock of 1340 MHz. The GPU ranks in the 53rd percentile among all GPUs, with an average benchmark score of 13559. Its nearest rivals are remarkably close in performance: the NVIDIA GeForce GTX 570 is effectively tied at 0% delta, the GTX 950 is 0.1% ahead, and the AMD Radeon Pro 455 is 1.1% behind.

The measured frame rates in Downfall directly reflect the GPU’s mid-range standing. The data shows a clear and steep drop in performance as settings are increased, particularly at higher resolutions. At 1920x1080, the RX 580 delivers playable frame rates: 102.9 FPS at Low, 87.1 FPS at Medium, and 70.8 FPS at High. However, the jump to Ultra at 1080p cuts performance to 44 FPS, indicating a significant demand increase. The trend becomes more pronounced at 2560x1440, where the card manages 71.1 FPS at Low, 62.7 FPS at Medium, and 50.4 FPS at High, but falls to 30.7 FPS at Ultra. At 4K (3840x2160), the RX 580 is overwhelmed; it can only muster 48 FPS at Low and 34.9 FPS at Medium, while High settings drop to 28.6 FPS and Ultra becomes effectively unplayable at 16.8 FPS.

The 8 GB VRAM likely plays a role in the steep performance cliff at Ultra settings, especially at higher resolutions. The GPU's Passmark G3D score of 8813 and its DirectX 12 score of 43 suggest it can handle modern APIs, but its raw compute power, at 6.175 TFLOPS, is insufficient for the heavier shader workloads in Downfall's Ultra preset. The data indicates that the RX 580 is best suited for 1080p and, to a lesser extent, 1440p gaming, but only when settings are kept in check.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and desired frame rate. For a smooth 60+ FPS experience, the data points to specific presets.

At 1920x1080, the Low preset delivers the highest average at 102.9 FPS, while Medium still provides a very playable 87.1 FPS. High settings are also viable at 70.8 FPS. However, the Ultra preset at 44 FPS sacrifices too much smoothness for the visual upgrade, making Medium the best balance for 1080p, offering a substantial frame rate buffer above 60 FPS while maintaining better visual fidelity than Low.

For 2560x1440, the situation tightens. The Low preset is the only one that comfortably exceeds 60 FPS, achieving 71.1 FPS. Medium comes close at 62.7 FPS, which is still technically playable but leaves little margin for error in more demanding scenes. High drops to 50.4 FPS, and Ultra falls to 30.7 FPS. The data suggests that Medium is the recommended preset for 1440p, as it provides a near-60 FPS average, but users prioritizing consistent frame pacing might prefer Low.

At 3840x2160, no preset provides a playable experience by modern standards. Low is the only setting that approaches 48 FPS, with Medium at 34.9 FPS and High at 28.6 FPS. Ultra is unplayable at 16.8 FPS. Therefore, 4K gaming is not recommended for this combination, but if attempted, Low is the only viable preset, though it still falls short of a smooth 60 FPS target.

How This Combo Ranks — use comboRankInGame vs other tested combos

The AMD Ryzen 9 9900X and AMD Radeon RX 580 combination ranks 1600 out of 1741 tested combos in Downfall. This places the pairing in the bottom 8% of all configurations tested, a ranking that is almost entirely attributable to the GPU. The Ryzen 9 9900X is a top-tier CPU, but the RX 580 is a legacy part from 2017 that holds the entire system back.

This ranking is consistent with the GPU’s performance percentile of 53%, which indicates it is an average card, but the pairing with a 94th percentile CPU creates a significant mismatch. The data reveals that the CPU is not the limiting factor; the bottleneck is the GPU’s inability to render the game at higher settings. The combo’s rank of 1600 suggests that most other tested combinations, likely featuring more balanced or modern GPUs, achieve better frame rates. The CPU’s high average benchmark score of 54450 does not translate into Downfall performance, as the game’s frame rates are strictly governed by the RX 580’s rendering capabilities. Essentially, the system has a high-performance engine paired with a modest transmission, and in Downfall, that transmission caps the overall output.

FAQ

Q: What is the best resolution for this CPU and GPU combo in Downfall?

A: Based on the measured data, 1920x1080 is the optimal resolution. It is the only resolution where the configuration can consistently exceed 70 FPS on High settings and approach 103 FPS on Low, providing the smoothest experience.

Q: Can this combo handle Ultra settings in Downfall?

A: No, not at any resolution. At 1080p, Ultra yields 44 FPS. At 1440p, it drops to 30.7 FPS, and at 4K, it falls to 16.8 FPS. The data shows Ultra settings are only playable at lower resolutions with significant performance sacrifices.

Q: How does the CPU compare to its closest rivals?

A: The Ryzen 9 9900X has an average benchmark score of 54450. This makes it 0.4% slower than the AMD Ryzen 9 9900X3D (54681), 0.7% faster than the Intel Core i7-14700F (54097), and 1.5% slower than the Intel Core Ultra 5 245K (55304).

Q: What is the performance difference between the RX 580 and its nearest rival?

Q: Is the CPU or GPU the bottleneck in this configuration?

A: The data indicates the GPU is the bottleneck. The frame rates drop dramatically with increased graphical settings, while the CPU’s high benchmark scores (e.g., 94th percentile) suggest it has ample headroom. The GPU’s 53rd percentile ranking and the steep FPS decline at higher presets confirm it is the limiting factor.

Q: What frame rate can be expected at 1440p on High settings?

A: The measured average FPS for 2560x1440 on High settings is 50.4. This is below the 60 FPS threshold, indicating a playable but not perfectly smooth experience, with visible frame drops likely in intense scenes.
