Downfall

The Intel Core i5-13400F paired with the AMD Radeon RX 580 presents a combination where the processor’s modern architecture meets a GPU from the Polaris generation. The measured FPS data in Downfall shows that this pairing is highly dependent on resolution and settings, with the CPU having ample headroom while the GPU becomes the limiting factor at higher loads. The i5-13400F sits in the 77th percentile among all CPUs, with a strong multi-threaded score of 22604 in Cinebench R23, while the RX 580 places in the 53rd percentile among GPUs. This imbalance explains why the combo ranks low overall, at 3426 out of 3716 tested combinations for this game.

Measured FPS Breakdown

The recorded data for Downfall covers three resolutions and four quality presets each. At 1920x1080, the pairing delivers playable performance across most settings. Low settings produce an average of 99.9 FPS, which is the highest recorded average for this combo in the entire test suite. Medium settings follow closely at 84 FPS, and High settings still clear the 60 FPS threshold comfortably with an average of 70.2 FPS. Ultra settings, however, drop the average to 41.5 FPS, which falls below the playable threshold. The spread from Low to Ultra at 1080p shows a drop of roughly 58 FPS, indicating that the RX 580’s 8 GB GDDR5 memory and 256.0 GB/s bandwidth are sufficient for lower presets but are overwhelmed by the demands of Ultra.

Moving to 2560x1440, the performance curve shifts downward. Low settings produce an average of 75.8 FPS, which remains above the 60 FPS playable threshold. Medium settings drop to an average of 57.8 FPS, just below the threshold, while High settings average 47.3 FPS and Ultra falls to 29.9 FPS. The data shows that at 1440p, only the Low preset maintains a smooth experience. The gap between Low and Medium at this resolution is 18 FPS, which is a significant jump considering the visual difference between those presets is often modest in horror titles. The RX 580’s pixel rate of 42.88 GPixel/s and texture rate of 193.0 GTexel/s appear to handle the lower settings well, but the 1440p resolution pushes the fill rate requirements beyond what the card can sustain at higher quality levels.

At 3840x2160, no settings achieve playable performance. Low settings average 47 FPS, which is the best result at this resolution, but still below the 60 FPS threshold. Medium averages 35.2 FPS, High averages 28.3 FPS, and Ultra averages 20.1 FPS. The progression from Low to Ultra at 4K shows a steady decline of roughly 27 FPS from the best to worst preset. The data indicates that 4K is not a viable option for this combination, as even the least demanding preset cannot reach the playable threshold. The 256.0 GB/s memory bandwidth of the RX 580 is likely the primary constraint at this resolution, as the card’s 8 GB frame buffer is tasked with moving significantly more data per frame.

The absence of min and max FPS values in the recorded data means only averages are available for analysis. This is worth noting because horror games often have sudden frame time spikes during scripted events or when loading new areas, and the average alone may not reflect the worst-case experience. The averages do show a consistent pattern, however: the CPU is not the bottleneck in any tested configuration. The i5-13400F’s single-thread score of 3191 in Cinebench R23 and its 16 threads provide far more processing capability than a game like Downfall, which was released in 2016, would require. The GPU is clearly the limiting factor at every resolution above 1080p Low or Medium.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-13400F show that this CPU is closely matched by several other processors in terms of average benchmark score. The AMD Ryzen 9 6900HS has an average score of 25284, which is essentially identical to the i5-13400F’s 25292, a delta of 0%. The Intel Core 5 120 scores 25362, 0.3% higher, and the AMD Ryzen 5 5600X3D scores 25365, also 0.3% higher. The AMD Ryzen 7 6800H scores 25201, 0.4% lower. For a gamer pairing this CPU with an RX 580, any of these processors would deliver nearly identical frame rates in Downfall, since the GPU is the bottleneck. The 10 cores and 16 threads of the i5-13400F provide plenty of headroom, and the rival CPUs with similar scores would not change the measured FPS in any meaningful way.

On the GPU side, the AMD Radeon RX 580 has an average score of 12928. Its nearest rivals include the NVIDIA GeForce RTX 3050 Ti Mobile at 12940, which is 0.1% higher, and the NVIDIA GeForce GTX 1660 SUPER at 12986, 0.4% higher. The AMD Radeon 740M scores 12870, 0.5% lower, and the AMD FirePro W5100 scores 12847, 0.6% lower. These deltas are all within 1%, meaning that swapping the RX 580 for any of these alternatives would produce nearly identical frame rates in Downfall. The GTX 1660 SUPER, for example, would likely show the same pattern of playable performance at 1080p Low through High, marginal performance at 1440p Low, and unplayable performance at 4K. The RTX 3050 Ti Mobile is a laptop part, but its benchmark score suggests it would behave similarly in this desktop context.

For builders considering alternatives, the data suggests that upgrading the GPU would yield the largest performance gain in Downfall. The CPU is already in the 77th percentile, and its nearest rivals show that it is well matched with other mid-range and high-end processors. The GPU, however, sits at the 53rd percentile, and its nearest rivals all cluster within 0.6% of its score. A meaningful upgrade would require moving to a GPU with a substantially higher benchmark score, which would shift the bottleneck dynamics entirely.

How This Combo Ranks

The combo rank in Downfall is 3426 out of 3716 tested combinations. This places the i5-13400F plus RX 580 in the bottom 7.8% of all systems tested for this game. The low rank is not surprising given the GPU’s age and performance class. The RX 580 was released in 2017 and is now marked as end-of-life, with a successor in the Vega architecture. The 14 nm Polaris 20 chip, with 5,700 million transistors and a die size of 232 mm², delivers 6.175 TFLOPS of FP32 compute, which is modest by modern standards.

The CPU, by contrast, is a current-generation part. The i5-13400F, released in 2023, uses Intel’s Raptor Lake architecture on a 10 nm process. Its 20 MB of shared L3 cache and support for both DDR4 and DDR5 memory make it a flexible choice. The 77th percentile ranking among all CPUs confirms that this processor is well above average. In Downfall, however, the game’s 2016 release date means it was designed for hardware that was contemporary at the time, and the RX 580 is actually from that same era. The pairing of a 2023 CPU with a 2017 GPU creates a significant imbalance, which the combo rank reflects.

The rank of 3426 out of 3716 means that 290 combinations performed worse in this game. That is a small fraction of the total, indicating that most tested systems deliver better results. The data shows that the RX 580 is the limiting factor, as the CPU has demonstrated strong synthetic performance across multiple benchmarks. In Cinebench R23, the i5-13400F scores 22604 multi-core and 3191 single-core, while in Geekbench it scores 11068 multi-core and 1996 single-core. These scores suggest that the CPU could drive a much more powerful GPU without becoming a bottleneck in a game like Downfall.

The Verdict

The verdict by resolution is clear. At 1920x1080, the combo achieves playable performance at High, Medium, and Low settings, with High averaging 70.2 FPS. This is the sweet spot for this pairing, offering the best visual quality that still clears the 60 FPS threshold. At 2560x1440, only Low is playable, with an average of 75.8 FPS. Medium at 1440p falls to 57.8 FPS, just shy of the threshold. At 3840x2160, no settings are playable, with Low averaging 47 FPS and Ultra averaging 20.1 FPS.

The verdict is that this PC can run Downfall, but only at 1080p and 1440p with reduced settings. The 1080p High preset is the recommended configuration for a balance of visual fidelity and smooth gameplay. At 1440p, Low is the only option that maintains a consistent 60 FPS average. The 4K resolution should be avoided entirely with this hardware, as even the lowest settings cannot reach the playable threshold.

The RX 580’s 8 GB of GDDR5 memory is sufficient for 1080p and 1440p gaming at lower presets, and the 256-bit memory bus provides adequate bandwidth for these resolutions. The card’s 2304 shading units and 144 texture mapping units are capable of handling the horror game’s lighting and shadow effects at lower settings, but the 32 ROPs limit the fill rate at higher resolutions and quality levels. The i5-13400F, with its 10 cores and 16 threads, ensures that the CPU never becomes a limitation in this title.

Best Settings per Resolution

At 1920x1080, the best settings that stay at or above 60 FPS are High, with an average of 70.2 FPS. This preset delivers the highest visual quality among the playable options at this resolution. Medium is also playable at 84 FPS, and Low at 99.9 FPS, but High offers the best balance. Ultra is not playable, as it drops to 41.5 FPS.

At 2560x1440, the best settings are Low, with an average of 75.8 FPS. This is the only preset that clears the 60 FPS threshold at this resolution. Medium falls just short at 57.8 FPS, and High and Ultra are further below at 47.3 FPS and 29.9 FPS respectively.

At 3840x2160, there are no playable settings. The best average is Low at 47 FPS, which is below the 60 FPS threshold. Medium averages 35.2 FPS, High averages 28.3 FPS, and Ultra averages 20.1 FPS. For users with a 4K display, the recommendation would be to run the game at a lower resolution, such as 1080p or 1440p, rather than attempting to play at native 4K. The data confirms that this combination is best suited for 1080p gaming, where it can handle High settings with a comfortable margin above the playable threshold.
