Downfall

The AMD Ryzen 7 9700F and AMD Radeon RX 580 pairing in Downfall presents a study in imbalance. The data shows a processor with immense headroom paired with a graphics card that caps performance early, creating a scenario where resolution scaling is dramatic and settings adjustments are critical for playability.

Resolution Scaling

The measured FPS data reveals a steep performance cliff as resolution increases, clearly identifying the GPU as the primary bottleneck. At 1080p with Low settings, the combo achieves 102 FPS, which drops to 73 FPS at 1440p and 45 FPS at 4K. This represents a 28.4% reduction from 1080p to 1440p, followed by a further 38.4% reduction from 1440p to 4K. The scaling pattern is consistent across all settings, but the severity intensifies with higher presets.

Looking at High settings, the frame rate falls from 68 FPS at 1080p to 49 FPS at 1440p (a 27.9% drop), then to 30 FPS at 4K (a 38.8% drop from 1440p). The Medium preset shows a similar trajectory: 83 FPS at 1080p, 60 FPS at 1440p, and 37 FPS at 4K. The Ultra preset is the most punishing, starting at 43 FPS at 1080p, falling to 31 FPS at 1440p, and collapsing to 19 FPS at 4K.

The pattern indicates that the RX 580's pixel throughput is the limiting factor. The card's 42.88 GPixel/s pixel rate and 256.0 GB/s memory bandwidth are simply insufficient for 4K workloads in this title. The Ryzen 7 9700F, with its 5.50 GHz boost clock and 8 cores, is not the constraint here; the frame rate deltas between resolutions are far too large to be attributed to CPU limitations. The data suggests that 1080p is the only resolution where this combination can deliver consistently smooth gameplay, while 1440p is borderline, and 4K is only viable on the lowest preset.

CPU Role

The Ryzen 7 9700F is a Zen 5 architecture processor built on a 4 nm process, featuring 8 cores and 16 threads. Its base clock of 3.80 GHz can boost up to 5.50 GHz, and it carries 32 MB of shared L3 cache. In the context of Downfall, a horror title from 2016, this CPU is massively overqualified. The game's engine does not appear to be heavily threaded, as the CPU's performance in synthetic benchmarks shows a strong single-thread score of 4691 in Passmark, which is more relevant than its multithread score of 36470 for this workload.

The CPU's 94th percentile ranking among all CPUs further underscores its high-end positioning. Compared to its nearest rivals, the Ryzen 7 9700F is essentially tied with the AMD Ryzen 9 7940HX (0.2% higher), Intel Core i7-14700KF (0.2% lower), AMD Ryzen 9 7950X (0.7% higher), and Intel Core i7-14700K (0.9% higher) in average benchmark score. These deltas are negligible, indicating that any of these processors would yield virtually identical performance in a GPU-limited scenario.

The data implies that the CPU is never the bottleneck in this pairing. Even at 1080p Low, where the frame rate peaks at 102 FPS, the GPU is still the limiting factor. If the CPU were struggling, we would expect to see diminishing returns when lowering resolution or settings, but the consistent scaling suggests the Ryzen 7 9700F is operating well within its capabilities. The 65W TDP and dual-channel DDR5 memory support with 89.6 GB/s bandwidth are more than adequate for feeding the RX 580 data.

Settings Recommendations

The measured rows provide clear guidance on the optimal settings for this hardware combination. At 1080p, the Medium preset offers the best balance, delivering 83 FPS with a minimum of 71 FPS and a maximum of 96 FPS. This is comfortably above the 60 FPS threshold for smooth gameplay, and the frame time consistency, evidenced by the min/max spread, suggests a stable experience. High settings at 1080p drop to 68 FPS, which is still playable but leaves less headroom for demanding scenes. Low settings at 1080p hit 102 FPS, but the visual quality hit is likely not worth the extra frames.

For 1440p, the Medium preset is the only reasonable choice, producing 60 FPS with a minimum of 51 FPS and a maximum of 69 FPS. This is right at the edge of acceptable performance. High settings at 1440p fall to 49 FPS, which introduces noticeable stutter in a horror title where smoothness is paramount. Low settings at 1440p reach 73 FPS, but the graphical downgrade undermines the atmospheric tension that Downfall relies on. Ultra at 1440p is not viable at 31 FPS.

At 4K, the data is grim. The Low preset manages 45 FPS, which is technically playable but far from ideal. Medium drops to 37 FPS, High to 30 FPS, and Ultra to 19 FPS. For this resolution, the Low preset is the only option, and even then, the experience will be subpar. The recommendation is clear: stick to 1080p Medium for the best combination of visual fidelity and performance, or 1440p Medium if you can tolerate occasional dips near 51 FPS.

How This Combo Ranks

The combination of the Ryzen 7 9700F and RX 580 ranks 2670 out of 2928 tested combos in Downfall. This places it in the bottom 8.8% of all pairings, which is a telling statistic. The rank reflects the GPU's age and limitations rather than the CPU's capabilities. The RX 580 is an end-of-life product from 2017, and its performance in this 2016 title is showing its age.

The low ranking is expected given the GPU's 53rd percentile among all GPUs. The RX 580's nearest rivals in synthetic benchmarks are the NVIDIA GeForce RTX 3050 Ti Mobile (0.1% higher), NVIDIA GeForce GTX 1660 SUPER (0.4% higher), AMD Radeon 740M (0.5% lower), and AMD FirePro W5100 (0.6% lower). These are all mid-range or older parts, confirming that the GPU is the weak link in this pairing.

The CPU, by contrast, ranks in the 94th percentile, making it one of the top processors available. This mismatch is the root cause of the poor combo ranking. The data indicates that pairing this CPU with a modern GPU would yield a dramatically better result, but as configured, the system is held back by the graphics card. The rank also suggests that most other tested combinations, including those with weaker CPUs but stronger GPUs, outperform this setup in Downfall.

GPU Role

The AMD Radeon RX 580 is a Polaris 20 chip built on a 14 nm process, featuring 2304 shading units, 144 texture mapping units, and 32 render output units. Its base clock is 1257 MHz with a boost clock of 1340 MHz, and it has 8 GB of GDDR5 memory on a 256-bit bus. The memory runs at 2000 MHz with 8 Gbps effective speed, providing 256.0 GB/s of bandwidth. The card's FP32 performance is 6.175 TFLOPS, and it supports DirectX 12 (12_0), Vulkan 1.3, and OpenGL 4.6.

In Downfall, the GPU is clearly the limiting component. The 4K results are particularly telling: even at Low settings, the card only manages 45 FPS, and at Ultra, it falls to 19 FPS. The 256.0 GB/s memory bandwidth is insufficient for 4K textures and high-resolution rendering, causing the steep performance drops observed. The card's 32 ROPs also limit pixel fill rate, which is critical at higher resolutions.

The GPU's synthetic benchmark scores corroborate its mid-range positioning. Its Passmark G3D score of 8813 and 3DMark Steel Nomad DX12 score of 1005 are modest. The Geekbench Vulkan score of 45173 and OpenCL score of 37453 show that the card is capable of compute workloads, but gaming performance is what matters here. The card's 53rd percentile ranking among all GPUs places it squarely in the middle of the pack, which is consistent with its observed performance in this title.

The RX 580's 185W TDP and dual-slot design are typical for its era, but the 450W suggested PSU requirement indicates it is not a power-efficient part by modern standards. The card's end-of-life status and 2017 release date mean it lacks modern features like hardware ray tracing, but Downfall does not require them. The data shows that the GPU's raw throughput is the primary constraint, and no amount of CPU headroom can compensate for its limitations.

Measured FPS Breakdown

The complete measured FPS data for the Ryzen 7 9700F and RX 580 in Downfall is as follows:

1920x1080:

• Low: 102 FPS average
• Medium: 83 FPS average, 71 FPS minimum, 96 FPS maximum
• High: 68 FPS average
• Ultra: 43 FPS average

2560x1440:

• Low: 73 FPS average
• Medium: 60 FPS average, 51 FPS minimum, 69 FPS maximum
• High: 49 FPS average
• Ultra: 31 FPS average

3840x2160:

• Low: 45 FPS average
• Medium: 37 FPS average, 32 FPS minimum, 43 FPS maximum
• High: 30 FPS average
• Ultra: 19 FPS average

The 1080p results show a clear hierarchy: Low is the fastest at 102 FPS, followed by Medium at 83 FPS, High at 68 FPS, and Ultra at 43 FPS. The gap between Medium and High is 15 FPS, while the gap between High and Ultra is 25 FPS, indicating that Ultra imposes a significant penalty. The Medium preset's min/max spread of 71-96 FPS is the only data point with full frame time information, and it shows a 25 FPS variance, which is acceptable for a horror game.

At 1440p, the same hierarchy holds but with lower absolute numbers. Low hits 73 FPS, Medium 60 FPS, High 49 FPS, and Ultra 31 FPS. The Medium preset's min/max of 51-69 FPS shows an 18 FPS variance, which is tighter than at 1080p, suggesting the GPU is working closer to its limits. The drop from High to Ultra is 18 FPS, a significant step down.

The 4K results are the most revealing. Low manages 45 FPS, Medium 37 FPS with a 32-43 FPS range, High 30 FPS, and Ultra 19 FPS. The Medium preset's min of 32 FPS is borderline unplayable, and the Ultra result of 19 FPS is a slideshow. The data clearly shows that 4K is not a viable resolution for this combination, regardless of settings. The 1080p Medium preset remains the sweet spot, offering the best compromise between visual quality and frame rate, with 1440p Medium as a secondary option for those with lower refresh rate displays.
