Downfall

Resolution Scaling

The measured frame rates for Downfall with the AMD Ryzen 5 5600F and AMD Radeon RX 570 reveal a steep performance curve as resolution climbs. At 1920x1080 with High settings, the combo delivers 62 FPS average, which is playable but not locked to high-refresh territory. Moving to 2560x1440 at the same High preset drops the average to 44 FPS, a 29% reduction. At 3840x2160, the average falls further to 27 FPS, representing a 56% loss from the 1080p baseline. This pattern points directly at the GPU as the limiting component—the resolution scaling is aggressive and consistent.

The Low preset tells a similar story with more headroom. At 1080p Low, the system reaches 92 FPS average, which is smooth for a horror title where responsiveness matters. At 1440p Low, that number drops to 66 FPS, a 28% decline. At 4K Low, the average lands at 41 FPS, which is 55% below the 1080p Low result. The proportional drops are nearly identical across presets, meaning the frame rate scaling is predictable and GPU-bound rather than CPU-bound.

Medium settings offer the most complete dataset, with min and max FPS values recorded at every resolution. At 1080p Medium, the average is 75 FPS with a min of 64 and max of 86. At 1440p Medium, the average is 54 FPS with a min of 46 and max of 62. At 4K Medium, the average is 33 FPS with a min of 28 and max of 38. The min-to-max spread tightens as resolution increases, suggesting that at lower resolutions the CPU can push frames higher, but at 4K the GPU saturates and frames bunch closer together.

Ultra settings are punishing across the board. At 1080p Ultra, the average is 39 FPS. At 1440p Ultra, it drops to 28 FPS. At 4K Ultra, the system manages only 17 FPS average. The gap between Low and Ultra at 1080p is 53 FPS—from 92 down to 39—which is a massive swing for a single preset change. The data indicates that Ultra is not viable at any resolution for this combo, and even 1080p Ultra falls below the 60 FPS threshold that most players would consider acceptable for a smooth experience.

The limiting component is clearly the GPU. If the CPU were the bottleneck, we would expect to see smaller FPS differences between 1080p and 1440p, since the CPU would be maxed out at both resolutions. Instead, the frame rate drops roughly 28-29% going from 1080p to 1440p, and another 38-39% going from 1440p to 4K. These are textbook GPU-bound scaling characteristics. The Ryzen 5 5600F, with its 6 cores and 12 threads, has enough processing headroom to feed the RX 570 at 1080p, but the Polaris-based GPU runs out of pixel-pushing capacity as resolution increases.

GPU Role

The AMD Radeon RX 570 is built on the Polaris 20 chip using the GCN 4.0 architecture on a 14 nm process. Its base clock is 1168 MHz with a boost clock of 1244 MHz. Memory runs at 1750 MHz, which translates to 7 Gbps effective on a 256-bit bus, yielding 224.0 GB/s of bandwidth. The card has 4 GB of GDDR5 memory, 2048 shading units, 128 texture mapping units, and 32 ROPs. Pixel rate is 39.81 GPixel/s and texture rate is 159.2 GTexel/s, with FP32 performance at 5.095 TFLOPS.

The 4 GB VRAM capacity is a significant factor in Downfall's 4K results. At 3840x2160, even the Low preset only manages 41 FPS average, and the Ultra preset falls to 17 FPS. While raw fill rate and shading power are the primary constraints, the 4 GB frame buffer likely compounds the issue at higher resolutions and quality settings. The memory bandwidth of 224.0 GB/s is respectable for the era but becomes a limiting factor when the GPU must stream textures and geometry for 4K output. The data shows a steep cliff between Medium and Ultra at every resolution, which suggests the VRAM capacity is being exhausted at Ultra settings.

The GPU's benchmark profile places it in the 74th percentile of all GPUs, with an average benchmark score of 28766. Its nearest rivals include the AMD Radeon RX 6800M with a score of 28874 (0.4% higher), the AMD Radeon R9 M295X at 28580 (0.7% lower), the AMD Radeon RX 470 at 28996 (0.8% higher), and the NVIDIA Quadro RTX 8000 at 28421 (1.2% lower). This places the RX 570 in a tightly contested performance band where small percentage differences separate competitors.

The GPU's clocks are modest by modern standards, but they are consistent with the Polaris generation. The boost clock of 1244 MHz is what the card actually sustains under load, and the 5.095 TFLOPS FP32 figure represents the theoretical peak. In Downfall, the GPU's capabilities translate to playable 1080p performance at Medium and High, with Low exceeding 90 FPS. The card was released in April 2017 with a launch MSRP of 169 USD, and its production status is end-of-life, which aligns with its performance position in the current benchmark landscape.

How This Combo Ranks

The combination of the AMD Ryzen 5 5600F and AMD Radeon RX 570 ranks 2797 out of 2928 tested combos in Downfall. This places the combo in the bottom 4.5% of all tested configurations, which is a stark assessment of its performance in this specific title. The ranking reflects the GPU's age and the game's demands at higher resolutions.

The CPU itself is not the limiting factor in this ranking. The Ryzen 5 5600F sits in the 85th percentile of all CPUs with an average benchmark score of 36945. Its nearest rivals are the Intel Core Ultra 5 225 at 36938 (0.0% difference), the AMD Ryzen 5 5500X3D at 37018 (0.2% higher), the AMD Ryzen AI 7 PRO 450 at 37093 (0.4% higher), and the Intel Core i9-12900T at 37112 (0.5% higher). This means the CPU is competitive with a broad range of modern processors, and its performance is not the reason for the low combo ranking.

The GPU, by contrast, sits in the 74th percentile of all GPUs, which is respectable for a standalone component but insufficient for demanding modern games at high resolutions. The combo ranking of 2797 out of 2928 reflects the fact that most tested combos pair more capable GPUs with comparable CPUs. The data suggests that if the RX 570 were paired with a weaker CPU, the ranking might be similar, but if the Ryzen 5 5600F were paired with a stronger GPU, the ranking would improve dramatically.

The delta between the CPU's high percentile (85th) and the GPU's lower percentile (74th) creates an imbalance. The CPU is capable of driving higher frame rates than the GPU can deliver, particularly at 1080p where the CPU has more headroom. This is evident in the 1080p Low result of 92 FPS, which is likely close to the CPU's maximum frame delivery in this game. At 1080p Ultra, the frame rate drops to 39 FPS, showing that the GPU is the bottleneck even at the most common gaming resolution.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo in Downfall depend on the target resolution. At 1920x1080, the Medium preset delivers 75 FPS average with a minimum of 64 FPS and maximum of 86 FPS. This is the best balance of visual quality and performance, as it maintains a frame rate above 60 FPS even at the low end. The High preset at 1080p drops to 62 FPS average, which is still playable but leaves less margin for demanding scenes. The Low preset at 1080p reaches 92 FPS average, which is excellent for competitive play, but the visual downgrade may diminish the horror atmosphere that Downfall relies on.

At 2560x1440, the Medium preset is the only viable option for smooth gameplay. It delivers 54 FPS average with a minimum of 46 FPS and maximum of 62 FPS. The High preset at 1440p drops to 44 FPS average, which is borderline for a horror game where reaction time matters. The Low preset at 1440p reaches 66 FPS average, which is playable but requires significant visual compromises. The Ultra preset at 1440p is not recommended, as it delivers only 28 FPS average.

At 3840x2160, no preset achieves 60 FPS. The Low preset is the most playable at 41 FPS average, followed by Medium at 33 FPS average, High at 27 FPS average, and Ultra at 17 FPS average. For 4K gaming, players should accept that this combo will not provide a smooth experience in Downfall, and the Low preset is the only reasonable choice if 4K resolution is mandatory. Otherwise, dropping to 1440p Medium or 1080p Medium provides a dramatically better experience.

The measured data shows that the Medium preset at 1080p is the sweet spot for this combo. The 75 FPS average with a 64 FPS minimum ensures that the game remains fluid during intense horror sequences, and the visual quality is sufficient to convey the game's atmosphere. Players who prioritize frame rate over visuals can use the Low preset at 1440p for 66 FPS average, but the 1080p Medium option offers a better overall experience.

CPU Role

The AMD Ryzen 5 5600F is a 5000 series processor based on the Zen 3 architecture, codenamed Vermeer. It has 6 cores and 12 threads, with a base clock of 3.00 GHz and a boost clock of 4.00 GHz. The CPU features a 32 MB shared L3 cache, 512 KB L2 cache per core, and 64 KB L1 cache per core. It is manufactured on a 7 nm process by TSMC, with 4,150 million transistors on a 74 mm² die. The TDP is 65 W, and it supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s. The CPU uses PCIe Gen 4 with 20 lanes and is unlocked for overclocking.

In Downfall, the CPU's role is to feed the GPU with frame data and handle game logic. The benchmark data shows that the CPU is not the limiting factor at any resolution. At 1080p Low, the system achieves 92 FPS average, which is a strong indicator that the CPU can push well beyond 60 FPS in this game. The CPU's PassMark single-thread score is 2872, and its multi-thread score is 19236, with an average benchmark score of 36945. These scores place the CPU in the 85th percentile of all CPUs.

The CPU's nearest rivals include the Intel Core Ultra 5 225 with an average score of 36938 (0.0% difference), the AMD Ryzen 5 5500X3D at 37018 (0.2% higher), the AMD Ryzen AI 7 PRO 450 at 37093 (0.4% higher), and the Intel Core i9-12900T at 37112 (0.5% higher). This tight clustering around the 37000 mark indicates that the Ryzen 5 5600F is competitively positioned within its performance class, and the small percentage differences between rivals would not meaningfully change the gaming experience in Downfall.

The CPU's 6 cores and 12 threads are sufficient for Downfall, which is a horror game that does not appear to be heavily multi-threaded based on the frame rate data. The fact that the 1080p Low preset achieves 92 FPS while the 1080p Ultra preset drops to 39 FPS confirms that the GPU is the bottleneck. If the CPU were struggling, we would expect to see similar frame rates across different GPU loads at the same resolution, but the data shows a wide spread that is directly attributable to GPU workload.

The CPU's memory bandwidth of 51.2 GB/s and dual-channel DDR4 support are adequate for feeding the GPU's 224.0 GB/s bandwidth. The PCIe Gen 4 interface provides ample bandwidth for the GPU, even though the RX 570 uses PCIe 3.0 x16, which is backward compatible. The CPU's 7 nm process and 65 W TDP contribute to efficient operation, but these factors have minimal direct impact on gaming performance in this title.

In summary, the Ryzen 5 5600F provides a solid foundation for the RX 570, but the GPU's limitations define the overall experience in Downfall. Players with this combo should focus on GPU-bound settings adjustments, such as lowering resolution or quality presets, to achieve playable frame rates. The CPU will not hold back performance at any setting or resolution tested.
