Downfall

The AMD Ryzen 5 5600 paired with the AMD Radeon RX 9070 delivers a compelling 1080p and 1440p experience in Downfall, but the data reveals a sharp performance cliff at 4K Ultra. The measured frame rates indicate a system that is heavily GPU-bound at higher resolutions, while the CPU’s strong single-thread performance ensures headroom at lower settings.

Resolution Scaling

The frame rate scaling from 1080p to 4K follows a predictable curve, but the magnitude of the drop varies significantly by preset. At High settings, the average FPS falls from 197.4 at 1920x1080 to 142 at 2560x1440, a 28% reduction, and then lands at 87.8 at 3840x2160, representing a 55.5% decline from the 1080p baseline. This pattern is consistent with a GPU that is becoming increasingly saturated as pixel count rises.

The Low preset shows even more dramatic scaling. The 1080p result of 294.4 FPS drops to 208.9 at 1440p and then to 131 at 4K. The percentage drop from 1080p to 4K is 55.5%, nearly identical to the High preset’s decline. This similarity suggests that even at Low settings, the resolution increase is the dominant factor, and the GPU’s rendering pipeline is the primary limiter across all presets.

Medium settings follow the same trajectory: 239.5 FPS at 1080p, 172.9 at 1440p, and 107.7 at 4K. The 4K figure is 55% lower than the 1080p result. Ultra is the outlier, with a 1080p score of 121.8 FPS, which drops to 86.1 at 1440p and plummets to 52.8 at 4K. The 4K Ultra result is 56.6% lower than 1080p Ultra, but the absolute value is far below the other presets, indicating that the Ultra preset’s additional rendering demands are disproportionately heavy at higher resolutions.

The data indicates that the RX 9070 is the limiting component at 1440p and 4K, as the FPS scales almost linearly with pixel count. At 1080p, however, the scaling between Low and Medium (294.4 to 239.5) suggests some CPU involvement, as the gap narrows compared to the 1440p-to-4K transitions. The 1080p Low result of 294.4 FPS approaches the practical ceiling for many displays, and the CPU’s ability to feed the GPU at this resolution is evident.

GPU Role

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture with a Navi 48 chip, fabricated on a 4 nm process. It carries 16 GB of GDDR6 memory on a 256-bit bus, providing 644.6 GB/s of bandwidth. The GPU’s boost clock is listed at 2520 MHz, with a game clock of 2070 MHz and a base clock of 1330 MHz. These specifications translate to a PassMark G3D score of 25381, placing it in the 79th percentile of all GPUs.

In Downfall, the GPU’s memory capacity appears sufficient, as even at 4K Ultra the system maintains a playable 52.8 FPS. The 16 GB frame buffer is likely adequate for this title’s textures, as the measured results do not show a catastrophic drop that would indicate memory swapping. The bandwidth of 644.6 GB/s is also a strong contributor, as the 4K High result of 87.8 FPS demonstrates the card can handle high-resolution rendering without stalling.

The RX 9070’s nearest rivals in the database include the NVIDIA Quadro GV100 and the AMD Radeon PRO W6400, with deltaPct values of 0.3% and 0.8% respectively. This places the RX 9070 within a narrow performance band of those cards, though the game-specific results show it excels in Downfall’s horror environments. The GPU’s DirectX 12 Ultimate support (12_2) is relevant, as the game’s High and Ultra presets likely leverage modern rendering features that benefit from this API level.

The pixel rate of 322.6 GPixel/s and texture rate of 564.5 GTexel/s are high, and the data shows that at 1080p High, the card achieves 197.4 FPS, which is a strong result. The FP32 throughput of 36.13 TFLOPS also supports the notion that the GPU has ample compute headroom for this title, but the Ultra preset’s 4K result of 52.8 FPS suggests that the additional shader complexity and post-processing effects in that mode are the primary bottlenecks.

CPU Role

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.50 GHz and a boost clock of 4.40 GHz, with a 32 MB shared L3 cache. The CPU’s PassMark single-thread score is 3256, and its multithread score is 21541, placing it in the 79th percentile of all CPUs. Its Cinebench R23 scores are 2584 single-core and 18309 multi-core.

In Downfall, the CPU’s role is most apparent at 1080p with lower presets. The 1080p Low result of 294.4 FPS is likely near the CPU’s maximum frame delivery capability, as the gap between Low and Medium at 1080p is 55.1 FPS, but the gap between 1440p Low and 4K Low is 77.9 FPS. This suggests that at 1080p, the CPU is working harder to keep up with the GPU’s frame output, while at higher resolutions, the GPU takes over as the primary limiter.

The Ryzen 5 5600’s 3DMark single-thread score of 882 and 2-thread score of 1737 indicate strong per-core performance, which is beneficial for a horror game that may have certain physics or AI calculations running on a single thread. The CPU’s 12 threads also provide enough parallelism for the game’s background tasks, as evidenced by the 1080p High result of 197.4 FPS, which is still well above the 144 Hz refresh rate common on gaming monitors.

The nearest rivals to the Ryzen 5 5600 include the Intel Core i7-11700F with a deltaPct of -0.9%, meaning the 5600 is slightly behind in average benchmark score. However, the game-specific data shows that the 5600 does not bottleneck the RX 9070 in Downfall at 1440p or 4K, as the FPS scales smoothly with resolution changes. The CPU’s 65W TDP and DDR4 memory support are sufficient for this workload, and the 51.2 GB/s memory bandwidth does not appear to be a constraint, as the FPS at 1440p High is 142, which is a strong result.

Settings Recommendations

The measured data points to a clear hierarchy of presets for this hardware combination. For users with a 1080p display, the High preset at 197.4 FPS is the optimal choice, as it provides a substantial visual upgrade over Medium (239.5 FPS) while still maintaining frame rates well above 144 Hz. The Low preset’s 294.4 FPS is excessive for most displays and sacrifices too much visual fidelity for a marginal gain in smoothness.

At 1440p, the High preset is the recommended setting. The 142 FPS average is comfortably above the 120 Hz threshold, and the visual quality is superior to Medium’s 172.9 FPS. The Ultra preset at 86.1 FPS is still playable, but the 55.9 FPS drop from High is significant and may not be worth the visual improvements in a horror title where smooth motion is critical for immersion.

For 4K users, the Medium preset at 107.7 FPS is the best balance of performance and quality. The High preset at 87.8 FPS is also viable, but the Medium setting offers a 19.9 FPS advantage while likely looking nearly identical on most displays. The Ultra preset at 52.8 FPS should be avoided unless the user prioritizes maximum graphical fidelity over frame rate stability, as the result is below the 60 FPS target for smooth gameplay.

The data suggests that the RX 9070’s 16 GB of VRAM is not a limiting factor at any preset, as even the 4K Ultra result does not show signs of memory-related stuttering. The system’s overall performance in Downfall is strong, with the 1080p High result placing the combo in the 576th rank out of 1741 tested combinations, which is in the top third of all pairings. Users should prioritize the High preset at 1080p and 1440p, and Medium at 4K, to get the best experience from this hardware.
