Downfall

Downfall, a 2016 horror title, presents a demanding workload for this pairing of an Intel Core i5-13400F and an AMD Radeon RX 570. The measured data reveals a system that is heavily constrained by the graphics card at higher resolutions, while the capable 10-core processor ensures the frame rates scale predictably with settings. The benchmark results indicate that this combination is best suited for 1080p gaming, where it can achieve playable frame rates, but struggles significantly as resolution increases.

Resolution Scaling

The most striking trend in the measured data is the dramatic impact of resolution on performance. At 1080p with Low settings, the system achieves an average of 92.6 FPS. Moving to 1440p at the same settings drops this to 69.1 FPS, a reduction of roughly 25%. At 4K, the frame rate plummets to 39.8 FPS, which is less than half of the 1080p result. This scaling pattern strongly suggests that the AMD Radeon RX 570, with its 4 GB of GDDR5 memory and 224.0 GB/s of bandwidth, becomes the primary limiting factor as pixel count increases.

The data shows an even more pronounced bottleneck at higher graphical presets. For instance, at High settings, the frame rate goes from 60.5 FPS at 1080p to 41.9 FPS at 1440p and then to just 27.9 FPS at 4K. This indicates that the combination of higher resolution and more complex shading is overwhelming the GPU's processing power (5.095 TFLOPS FP32) and memory subsystem. The Core i5-13400F, which sits in the 82nd percentile of all CPUs, is unlikely to be the bottleneck here, as its benchmark scores, such as a Cinebench R23 multi-core score of 21279, suggest it has ample headroom.

The scaling from Ultra to other settings is also telling. At 4K, the drop from Low (39.8 FPS) to Ultra (16.5 FPS) represents a 58% performance penalty. This is a clear sign that the RX 570's fillrate and memory bandwidth are being saturated. The game is not CPU-bound at these resolutions; instead, the data implies a pure GPU limitation. The 1080p results, where the frame rate can exceed 90 FPS on Low, are the only territory where this combo begins to feel fluid, suggesting that for higher resolutions, a more powerful GPU would be necessary.

FAQ

Q: What is the best resolution for playing Downfall with this hardware?

A: Based on the measured FPS, 1920x1080 is the only resolution where the system consistently provides playable frame rates. At 1080p, even the High preset achieves 60.5 FPS, while Low and Medium presets reach 92.6 and 77.9 FPS, respectively. The 1440p and 4K results show averages that dip below 60 FPS on most presets.

Q: How does the Ultra preset compare to High at 1080p?

A: The performance cost of Ultra is significant. At 1920x1080, the High preset averages 60.5 FPS, but the Ultra preset drops to 37.7 FPS. This is a 38% reduction in frame rate for the highest visual fidelity, which may not be worth the trade-off for smoother gameplay.

Q: Is the CPU a bottleneck in this game?

A: The data suggests the CPU is not the primary limiter. The Intel Core i5-13400F has 10 cores and 16 threads, with a boost clock of 4.60 GHz, and its performance is in the 82nd percentile of all CPUs. The consistent FPS scaling with resolution points to the GPU being the limiting component, especially since the CPU is capable of high scores in multi-threaded benchmarks like Cinebench R23.

Q: What kind of performance can I expect at 1440p?

A: At 2560x1440, the system struggles to maintain high frame rates. The best result is with Low settings at 69.1 FPS. Medium and High settings yield 54.4 and 41.9 FPS, respectively, while Ultra falls to 25.9 FPS. For a smooth experience, you would need to rely on the Low preset.

Q: How does the RX 570's memory capacity affect performance?

A: The GPU has 4 GB of GDDR5 memory on a 256-bit bus. The significant frame rate drops at 4K, particularly on the Ultra preset (16.5 FPS), suggest that the memory capacity and bandwidth are insufficient for the high-resolution textures and data demands, making it a key factor in the performance ceiling.

Q: What is the single best settings/resolution combination for this combo?

A: The 1920x1080 Medium preset offers a good balance, with an average of 77.9 FPS. This provides a significant improvement over the High preset's 60.5 FPS while still offering better visuals than the Low preset's 92.6 FPS, making it a strong choice for a smooth experience.

CPU Role

The Intel Core i5-13400F is a Raptor Lake-S part with 10 cores and 16 threads, running at a base clock of 2.50 GHz and a boost clock of 4.60 GHz. This processor is a robust component, as evidenced by its Cinebench R23 multi-core score of 21279 and a single-core score of 3004. Its performance places it in the 82nd percentile of all CPUs, and its nearest rivals, such as the Intel Core i7-13620H (0.1% faster) and the AMD Ryzen 5 5600X3D (0.5% slower), show that it is a highly competitive chip.

In the context of Downfall, the processor's role appears to be supportive rather than dominant. The measured FPS data shows a clear pattern where performance degrades with resolution, which is a hallmark of a GPU bottleneck. If the CPU were the limiting factor, we would expect to see similar frame rates across different resolutions, as the processor's workload would remain constant. Instead, the 1080p Low setting result of 92.6 FPS versus the 4K Low setting result of 39.8 FPS confirms that the GPU is the constraining element.

The processor's high thread count and clock speeds ensure it is more than capable of feeding the GPU with data, preventing a CPU-side stall. The data implies that the i5-13400F has enough headroom to handle the game's logic and physics without becoming a hindrance. Its performance in synthetic benchmarks, like the 3DMark max threads score of 7307, further reinforces that it is not the weak link in this pairing. The bottleneck is decisively on the graphics side.

How This Combo Ranks

Within the database of tested combos for Downfall, this specific configuration of the Intel Core i5-13400F and AMD Radeon RX 570 is ranked 1655 out of 1741 combinations. This places it in the bottom 5% of all tested systems, indicating that it is a lower-performing pairing for this specific game. This low rank is directly attributable to the graphics card, as the CPU is a high-performing part. The GPU's 74th percentile ranking, while decent, is far below the CPU's 82nd percentile, creating an imbalance.

The data shows that this combo is not competitive with the top-tier systems in the database. The rank suggests that most other hardware combinations tested provide higher frame rates. This is consistent with the GPU's age and its measured performance in modern benchmarks, such as a 3DMark Steel Nomad DX12 score of 880. While the CPU is a modern, powerful component, it is paired with a graphics card that was released in 2017, and the results reflect the GPU's limitations.

This ranking serves as a clear indicator that while the CPU is a strong foundation, the overall system performance is held back significantly by the GPU. For a game like Downfall, which appears to be graphically intensive, the low combo rank highlights that users with this setup will likely have to compromise significantly on visual settings or resolution to achieve acceptable performance, as the data from the measured FPS confirms.

Settings Recommendations

The measured FPS data provides a clear hierarchy for optimizing the experience in Downfall. The primary goal is to maintain a fluid frame rate, and the data shows that 1080p is the most viable resolution. At 1920x1080, the Low preset delivers 92.6 FPS, which is the highest average recorded for this combo. This setting provides the smoothest experience, ideal for a horror game where responsiveness is key.

For a better visual experience without sacrificing too much performance, the Medium preset at 1080p is the recommended choice. It yields an average of 77.9 FPS, which is still well above the 60 FPS threshold for smooth gameplay. This represents a good balance, offering improved textures and effects over Low while maintaining high frame rates. The High preset at 1080p is also playable, with an average of 60.5 FPS, but it is right at the edge of what is considered fluid.

The Ultra preset should be avoided at all resolutions. At 1080p, it drops to 37.7 FPS, and at 1440p, it falls to 25.9 FPS. The data clearly shows that the cost of enabling Ultra settings is too high for the RX 570 to handle. For users with a 1440p monitor, the Low preset provides an average of 69.1 FPS, which is the only playable option at that resolution. 4K is not recommended, as even the Low preset only manages 39.8 FPS.

Measured FPS Breakdown

At 1920x1080, the system performs best. The Low preset achieves an average of 92.6 FPS. The Medium preset averages 77.9 FPS, and the High preset averages 60.5 FPS. The Ultra preset is significantly slower, with an average of 37.7 FPS. This shows a clear performance hierarchy based on settings.

At 2560x1440, the performance drops considerably. Low settings yield an average of 69.1 FPS. The Medium preset averages 54.4 FPS, and the High preset averages 41.9 FPS. The Ultra preset is the slowest, with an average of 25.9 FPS. Only the Low preset here provides a frame rate above 60 FPS.

At 3840x2160, the system is heavily strained. The Low preset is the fastest, with an average of 39.8 FPS. The Medium preset averages 36.7 FPS, and the High preset averages 27.9 FPS. The Ultra preset produces a nearly unplayable average of 16.5 FPS. No setting at this resolution reaches a playable 60 FPS, confirming the 4K resolution is not suitable for this hardware combo.

GPU Role

The AMD Radeon RX 570 is the definitive bottleneck in this configuration. With a 4 GB memory buffer and a 256-bit bus, it provides 224.0 GB/s of bandwidth. While its 2048 shading units and 32 ROPs can handle 1080p gaming adequately, the data shows that its capabilities are quickly exhausted at higher resolutions. The GPU's performance in synthetic benchmarks, such as a Geekbench OpenCL score of 32084, reflects its mid-range status.

The frame rate data is a direct reflection of the GPU's workload. The transition from 1080p to 4K at a given setting shows a massive drop in performance, which is a classic sign of the GPU's fillrate and memory bandwidth being saturated. For example, the High preset goes from 60.5 FPS at 1080p to 27.9 FPS at 4K. This is not a CPU limitation; it is the GPU struggling to process the increased pixel data.

The GPU's 74th percentile ranking and its proximity to rivals like the NVIDIA GeForce RTX 5060 (0.2% faster) and AMD Radeon RX 7700 XT (0.2% faster) in average benchmark scores are interesting, but they do not translate to high-end 4K performance in this game. The data implies that while the RX 570 is a competent 1080p card, its 14 nm Polaris architecture and limited memory capacity are not suited for the demands of Downfall at higher resolutions. The 4 GB VRAM is likely a critical weakness, causing the significant frame rate drops seen in the 4K Ultra result of 16.5 FPS.
