A: Medium settings at 1080p yield 84 FPS average, which is the highest preset that maintains a comfortable margin above 60 FPS. Low settings reach 99.9 FPS but sacrifice visual quality for a relatively small framerate gain.

*Q: How does this combo rank among all tested systems for Downfall?*

A: The combo ranks 1622 out of 1741 total combinations, placing it in the bottom 7% of the database. This rank reflects the GPU’s 53rd percentile standing among all GPUs, while the CPU sits in the 82nd percentile among all CPUs.

GPU Role

The AMD Radeon RX 580 is the definitive bottleneck in this pairing. With a base clock of 1257 MHz and a boost clock of 1340 MHz, the Polaris 20 chip delivers 6.175 TFLOPS of FP32 compute. The data shows this translates to 28.3 FPS average at 4K High settings, a figure that drops further to 20.1 FPS at Ultra. The GPU’s 53rd percentile ranking among all GPUs explains why performance collapses as resolution scales.

The 8 GB VRAM on a 256-bit bus provides 256.0 GB/s of bandwidth, which is sufficient for Downfall’s textures at 1080p but becomes insufficient at 4K. The measured 47 FPS at 4K Low settings versus 28.3 FPS at 4K High settings shows a 66% performance swing that is characteristic of a GPU hitting both fill-rate and memory-bandwidth walls. The GPU’s 32 ROPs and 144 TMUs produce a pixel rate of 42.88 GPixel/s and texture rate of 193.0 GTexel/s, figures that align with the observed framerate drops when moving from 1440p to 4K.

The RX 580’s synthetic scores reinforce its position: a Passmark G3D score of 8813 and a 3DMark Steel Nomad DX12 score of 1005. Compared to its nearest rivals, the GPU is effectively tied with the GTX 570 and GTX 950, both of which are older architectures. This is a card that was released in 2017 and is now end-of-life, and Downfall’s measured results reflect that aging hardware.

Resolution Scaling

The framerate deltas between 1080p and 4K are severe, confirming the GPU as the limiting component. At High settings, the average FPS drops from 70.2 at 1080p to 47.3 at 1440p (a 33% reduction) and then to 28.3 at 4K (a further 40% reduction from 1440p). This near-linear scaling with pixel count is the signature of a GPU-bound scenario.

Low settings exhibit the same pattern: 99.9 FPS at 1080p, 75.8 FPS at 1440p, and 47 FPS at 4K. The 4K Low result is still below the 60 FPS target, meaning that even at the lowest visual preset, the RX 580 cannot deliver a smooth 4K experience. The gap between 1080p and 1440p at Low settings is 24.1 FPS, while the gap between 1440p and 4K is 28.8 FPS, showing that the GPU’s performance degradation accelerates at higher pixel counts.

Ultra settings are the clearest indicator of the bottleneck: 41.5 FPS at 1080p, 29.9 FPS at 1440p, and 20.1 FPS at 4K. The 1080p Ultra result is only marginally above the 4K Low result, demonstrating that the GPU’s compute and memory resources are exhausted regardless of resolution when visual fidelity is maxed. The data indicates that the i5-13400F has ample headroom, as its single-thread score of 3004 in Cinebench R23 and 3634 in Passmark single-thread would not constrain these framerates.

Settings Recommendations

For a playable experience, Medium settings at 1080p provide the optimal balance in the measured data. The 84 FPS average is 14 FPS higher than High settings and only 15.9 FPS lower than Low settings, while offering substantially better visual quality than Low. This preset stays well above the 60 FPS threshold, making it the recommended choice for mainstream displays.

At 1440p, the data shows that only Low settings (75.8 FPS) and Medium settings (57.8 FPS) approach acceptable playability. High settings drop to 47.3 FPS, and Ultra falls to 29.9 FPS. For 1440p users, Low settings are the only preset that maintains a comfortable margin above 60 FPS, though Medium is viable if the user tolerates sub-60 framerates.

4K is not a viable resolution for this combo. The best measured result is 47 FPS at Low settings, which is below the 60 FPS target and still represents a degraded visual experience. High settings at 4K produce 28.3 FPS, and Ultra produces 20.1 FPS, both of which are insufficient for smooth gameplay in a horror title where responsiveness matters. Users should stick to 1080p Medium or 1440p Low.

Measured FPS Breakdown

At 1920x1080, the measured average framerates are: Low 99.9 FPS, Medium 84 FPS, High 70.2 FPS, and Ultra 41.5 FPS. The spread between Low and Ultra is 58.4 FPS, indicating that the GPU’s compute units are heavily taxed by Ultra settings.

At 2560x1440, the averages are: Low 75.8 FPS, Medium 57.8 FPS, High 47.3 FPS, and Ultra 29.9 FPS. The 1440p results show a compression of the settings range, with only 45.9 FPS separating Low from Ultra, compared to 58.4 FPS at 1080p.

At 3840x2160, the averages are: Low 47 FPS, Medium 35.2 FPS, High 28.3 FPS, and Ultra 20.1 FPS. The 4K results compress further, with a 26.9 FPS spread between Low and Ultra. The 4K Low result of 47 FPS is nearly identical to the 1440p High result of 47.3 FPS, showing that resolution scaling and settings scaling trade off almost one-to-one at this performance tier.

CPU Role

The Intel Core i5-13400F is vastly overqualified for this GPU pairing. With 10 cores and 16 threads across Raptor Lake architecture, the CPU boosts to 4.60 GHz and delivers a Cinebench R23 multicore score of 21279 and a single-core score of 3004. The 82nd percentile ranking among all CPUs places it far above the GPU’s 53rd percentile, confirming that the processor is never the limiting factor in Downfall.

The CPU’s 20 MB shared L3 cache and 1.25 MB per-core L2 cache provide ample bandwidth for game logic and scene management. Its Passmark single-thread score of 3634 ensures that even the most demanding single-threaded tasks in Downfall are handled without stutter. The data shows no scenario where the CPU’s performance ceiling is reached: at 1080p Low settings, the GPU produces 99.9 FPS, and the CPU’s 3DMark single-thread score of 960 suggests it could drive far higher framerates if paired with a stronger GPU.

Compared to its nearest rivals, the i5-13400F is within 0.1% of the Intel Core i7-13620H and 0.5% below the AMD Ryzen 5 5600X3D in average benchmark scores. This places it in a performance class that is entirely wasted on the RX 580, as the GPU’s 6.175 TFLOPS compute cannot translate the CPU’s headroom into additional frames.

How This Combo Ranks

The combo ranks 1622 out of 1741 tested combinations for Downfall, placing it in the bottom 7% of the database. This low rank is directly attributable to the GPU, as the CPU’s 82nd percentile standing is dragged down by the GPU’s 53rd percentile performance.

The measured data supports this ranking: the combo achieves its best result of 99.9 FPS only at 1080p Low settings, while the majority of tested combos likely exceed this at higher presets. The 4K Ultra result of 20.1 FPS is below the playability threshold for most users, and even the 1080p Ultra result of 41.5 FPS is marginal.

The GPU’s nearest rivals—the GTX 570, GTX 950, Radeon Pro 455, and P106-090—are all older or lower-tier parts, confirming that the RX 580 is at the bottom of the modern GPU hierarchy. The CPU’s nearest rivals, including the Core i7-13620H and Ryzen 5 5600X3D, are far more capable processors, highlighting the mismatch in this pairing. For users with this combo, the data suggests that upgrading the GPU would yield dramatic framerate improvements, while the CPU can remain in place for future builds.
