Downfall

The AMD Ryzen 9 5900X paired with the AMD Radeon RX 5700 XT produces a combination that is heavily skewed toward CPU performance in Downfall. The 12-core, 24-thread processor, based on the Zen 3 architecture, offers substantial headroom for this horror title, which appears to be less demanding on core scaling than on raw single-thread throughput. The CPU's boost clock of 4.80 GHz and base clock of 3.70 GHz, combined with a 64 MB L3 cache, provide strong fundamentals for frame pacing. However, the data indicates that the GPU becomes the primary constraint at higher resolutions and settings, making the CPU’s potential largely untapped in this specific configuration.

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

The Ryzen 9 5900X is a high-end desktop processor with 12 cores and 24 threads, running on the AMD Socket AM4 platform. Its architecture, Zen 3 (codename Vermeer), is built on a 7 nm process and supports DDR4 memory in a dual-channel configuration, with a memory bandwidth of 51.2 GB/s. The processor’s benchmark scores are robust: it achieves a Cinebench R23 multicore score of 33150 and a single-core score of 4680. In Geekbench, it scores 11877 multicore and 2202 single-core. These results place it in the 90th percentile of all CPUs tested, with an average benchmark score of 39453.

Relative to its nearest rivals, the 5900X is essentially tied with the AMD EPYC 4245P, which scores 39383, a mere 0.2% difference. It is also within 1% of the Intel Core i7-13700 (39857, -1% delta) and 0.9% ahead of the Intel Core i7-13700F (39095). This suggests that for Downfall, the CPU is not a limiting factor at any of the tested resolutions. The game’s frame rates scale more dramatically with GPU settings and resolution, which indicates that the workload is primarily GPU-bound once the resolution exceeds 1080p. The processor’s high single-thread performance, evidenced by its Passmark single-thread score of 3469, ensures that even at 1080p with Low settings, where the average FPS reaches 186.7, the CPU does not bottleneck the frame delivery.

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

The AMD Radeon RX 5700 XT, based on the RDNA 1.0 architecture (Navi 10), is the clear performance limiter in this combo. It features 8 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 448.0 GB/s. The GPU’s clocks are set at a base of 1605 MHz, a game clock of 1755 MHz, and a boost clock of 1905 MHz. While these specifications are respectable for a card of its generation, the benchmark data shows that it sits in the 68th percentile of all GPUs, with an average benchmark score of 24731. Its nearest rivals include the NVIDIA RTX A5000 Mobile (24763, -0.1% delta) and the Intel Arc A350M (24647, 0.3% delta), indicating that the RX 5700 XT is performing as expected relative to its peers.

In Downfall, the GPU’s capabilities directly dictate the achievable frame rates at higher quality presets. At 4K Ultra, the average FPS drops to 36.4, which is below the 60 FPS threshold many players consider playable. The card’s 8 GB of VRAM appears sufficient for the tested settings, but the raw compute power—9.754 TFLOPS FP32—is insufficient to maintain high frame rates at 4K with Ultra effects. The data suggests that the GPU is the bottleneck in this pairing, as the CPU’s performance headroom is not fully utilized when the resolution and settings push the GPU to its limits.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a classic GPU-bound scaling pattern. Moving from 1080p to 1440p to 4K at the same settings shows a consistent, significant drop in performance. At High settings, the average FPS goes from 126 at 1080p, down to 93 at 1440p, and further to 54.4 at 4K. This represents a 26% drop from 1080p to 1440p, and a further 42% drop from 1440p to 4K. The pattern is similar at Medium settings, where the frame rate falls from 153.6 at 1080p to 107.6 at 1440p, and then to 66.3 at 4K.

The scaling indicates that the RX 5700 XT is the limiting component, as the frame rate drops are directly proportional to the increase in pixel count. If the CPU were the bottleneck, we would expect to see a plateau at lower resolutions, with frame rates remaining relatively flat between 1080p and 1440p. Instead, the continuous decline across all resolutions points to the GPU being saturated. The data also shows that the Ultra preset is particularly punishing, with a drop from 76.7 FPS at 1080p to 56.9 at 1440p and finally 36.4 at 4K. This suggests that the Ultra preset introduces effects that disproportionately impact the GPU’s fill rate and shading capabilities.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested combinations for Downfall, this specific pairing of the Ryzen 9 5900X and RX 5700 XT holds a rank of 1318 out of 1741 total combos. This places it in the lower-middle tier of all tested systems, which is a direct consequence of the GPU’s relatively modest performance compared to the CPU. The rank indicates that while the CPU is among the top 10% of processors, the GPU’s 68th percentile standing drags the overall combo down.

This ranking is not surprising given the data. A high-end CPU paired with a mid-range GPU creates an imbalance that is reflected in the game’s frame rates. The combo’s rank of 1318 out of 1741 suggests that many other systems, likely with more balanced CPU-GPU pairings, deliver better overall performance in Downfall. For users of this combo, the implication is clear: the GPU should be the first upgrade target to improve performance in this title, as the CPU has significant untapped potential.

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

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution. At 1080p, the High preset provides an excellent experience with an average of 126 FPS, which is well above the 60 FPS threshold and offers a good balance of visual quality and performance. The Medium preset is also viable at 1080p, delivering 153.6 FPS, but the visual improvement from Medium to High is often worth the 27.6 FPS cost. The Ultra preset at 1080p drops to 76.7 FPS, which is still playable but not ideal for high-refresh-rate monitors.

At 1440p, the High preset is the recommended choice, yielding an average of 93 FPS. This is a comfortable frame rate for most gamers. The Medium preset offers 107.6 FPS, but the High preset’s visual fidelity is worth the 14.6 FPS reduction. The Ultra preset at 1440p produces 56.9 FPS, which is below 60 and should be avoided for a smooth experience. At 4K, the situation is more difficult. The High preset produces 54.4 FPS, which is marginally below 60, making it the best playable option. The Medium preset at 66.3 FPS is also acceptable, but the Low preset at 87.1 FPS is the only way to achieve a comfortable margin above 60 FPS at this resolution.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The complete measured FPS data for this combo is as follows. At 1920x1080, the average FPS ranges from a high of 186.7 on Low settings to a low of 76.7 on Ultra. The Medium preset delivers 153.6 FPS, while High settings achieve 126 FPS. At 2560x1440, the frame rates decrease across the board: Low settings produce 138.1 FPS, Medium 107.6 FPS, High 93 FPS, and Ultra drops to 56.9 FPS. At 3840x2160, the performance is significantly lower: Low settings provide 87.1 FPS, Medium 66.3 FPS, High 54.4 FPS, and Ultra falls to 36.4 FPS.

The data shows a clear trend: the gap between Low and Ultra settings widens as resolution increases. At 1080p, the difference between Low and Ultra is 110 FPS (186.7 vs 76.7). At 1440p, the difference is 81.2 FPS (138.1 vs 56.9). At 4K, the difference narrows to 50.7 FPS (87.1 vs 36.4). This narrowing indicates that at 4K, the GPU is so heavily loaded that the settings differences have a proportionally smaller impact on the absolute frame rate. For a smooth experience, users should target High settings at 1080p or 1440p, and Medium or Low at 4K, depending on their preference for visual quality versus frame rate stability.
