Downfall

The pairing of AMD’s Ryzen 5 3600 with NVIDIA’s GeForce RTX 4080 SUPER is an unusual study in bottleneck dynamics within Downfall. The data reveals a system where the GPU’s immense raw power is frequently held in check by the older Zen 2 processor, yet the combination still produces remarkably high frame rates. This analysis breaks down the measured performance across resolutions and settings, focusing on what the numbers indicate about the limiting components.

Resolution Scaling

The frame rate drop from 1080p to 4K is telling. At 1080p with Low settings, the combo produces 283.5 FPS, but at 4K Low, it falls to 175.1 FPS — a decline of roughly 38%. This scaling pattern is the classic signature of a CPU bottleneck at lower resolutions. At 1080p, the Ryzen 5 3600 is likely maxing out its 6 cores and 12 threads, preventing the RTX 4080 SUPER from stretching its legs. The GPU’s 3DMark Steel Nomad score of 6600 and Passmark G3D score of 34245 suggest it is capable of far more than the CPU allows at these settings.

Moving to 4K, the pendulum swings. At 4K Ultra, the frame rate drops to 75.4 FPS, which is a 55% reduction from the 1080p Ultra score of 166.9 FPS. This steeper drop at the highest settings indicates a shift toward a GPU-bound scenario. The RTX 4080 SUPER’s 16 GB of GDDR6X memory and 736.3 GB/s bandwidth are being taxed heavily, while the CPU has more headroom to keep up with the lower instruction count per frame. The fact that the 4K High score (119.5 FPS) is higher than the 1440p Ultra score (118.5 FPS) is curious; it suggests that the Ultra preset introduces effects that disproportionately strain the CPU, even at lower resolutions.

The most telling data point is the scaling from 1440p to 4K at Low settings: the drop is from 256.4 FPS to 175.1 FPS, a 32% reduction. This is a moderate decline, indicating that while the GPU is becoming more relevant, the CPU still imposes a ceiling on performance. The 1080p to 1440p gap at Low is smaller (283.5 to 256.4 FPS), which further reinforces the idea that the CPU is the primary limiter until the resolution becomes heavy enough to flip the balance.

Settings Recommendations

The measured rows suggest that the High preset offers the most balanced experience for this hardware combination. At 1440p High, the combo achieves 188.7 FPS, which is above the refresh rate of most high-end monitors and only 18% below the Low preset’s 256.4 FPS. The jump from High to Ultra at 1440p is severe — a 37% drop to 118.5 FPS — which indicates that the Ultra preset introduces CPU-heavy effects that this processor struggles to manage.

At 4K, the High preset delivers 119.5 FPS, which is playable and visually robust, while Ultra drops to 75.4 FPS. The Medium preset at 4K (146.8 FPS) is also viable, but High offers a better visual quality-to-performance ratio given the modest 27 FPS difference between them. At 1080p, the High preset’s 250.1 FPS is nearly indistinguishable from Low’s 283.5 FPS in terms of smoothness, making High the clear choice for competitive play without sacrificing visuals.

The data implies that High is the sweet spot because it avoids the CPU-bound penalty of Ultra while still leveraging the GPU’s capabilities. The Ultra preset’s performance collapse suggests it is not optimized for 6-core processors, as the Ryzen 5 3600’s Cinebench R23 multi-core score of 15045 is modest by modern standards. For users with 144Hz displays, 1440p High is the recommended pairing. For 4K, High remains the best option, as it keeps frame rates above 100 FPS while maintaining visual fidelity.

GPU Role

The RTX 4080 SUPER is a monstrous GPU, but its role in this pairing is often secondary. Its 16 GB of VRAM is more than sufficient for Downfall at any resolution, and the GDDR6X memory running at 23 Gbps effective provides a 736.3 GB/s bandwidth that prevents any memory-related stutters. The boost clock of 2550 MHz and 10240 shading units ensure that, when the CPU allows, the GPU can push frame rates to extreme levels.

The Passmark G3D score of 34245 places the GPU in the 88th percentile of all GPUs, and its nearest rival, the AMD Radeon RX 6900 XT, is only 0.2% behind. This indicates that the GPU is performing as expected, and any performance shortfalls in Downfall are not due to GPU limitations. The GPU’s FP32 performance of 52.22 TFLOPS is astronomical, but at 1080p Low, the frame rate of 283.5 FPS suggests the CPU is the bottleneck, as the GPU is likely idle for significant portions of each frame.

The VRAM capacity becomes relevant at 4K Ultra, where the frame rate drops to 75.4 FPS. This is not a VRAM capacity issue but rather a rendering load issue. The GPU’s pixel rate of 285.6 GPixel/s and texture rate of 816.0 GTexel/s are taxed heavily at this resolution, but the CPU’s inability to feed the GPU efficiently at lower resolutions is the more significant constraint. The data shows that the GPU’s role expands as resolution increases, but it never fully takes over until the Ultra preset at 4K.

How This Combo Ranks

In the grand scheme of tested combinations for Downfall, this pairing ranks 233rd out of 1741 combos. This places it in the top 13.4% of all tested systems, which is impressive but not dominant. The ranking suggests that while the RTX 4080 SUPER is a top-tier GPU, the Ryzen 5 3600 holds the combo back from reaching the upper echelons of performance.

The CPU’s percentile of 76 against all CPUs is respectable, but its nearest rivals include the Intel Core i5-11400 (0.1% higher average score) and the AMD Ryzen 5 1600 (0.2% lower). This indicates that the Ryzen 5 3600 is a mid-range processor in 2024 terms, and it is being paired with a GPU that is in the 88th percentile. The mismatch is evident in the frame rate data, where the combo’s 1080p scores are high but not as high as they would be with a newer CPU.

The combo ranking of 233 implies that there are 232 other combinations that achieve higher frame rates in Downfall. These are likely systems with newer CPUs (such as Ryzen 7000-series or Intel 12th/13th-gen) paired with similar or better GPUs. The RTX 4080 SUPER’s nearest rival, the RTX 5070 Ti (2.9% lower average score), suggests that even a slightly newer GPU would not fully compensate for the CPU’s age in this game.

FAQ

A: Yes, the data indicates this clearly. At 1080p Low, the combo produces 283.5 FPS, but this is likely CPU-limited. The CPU’s 3DMark single-thread score of 696 and multi-thread score of 4605 are modest compared to modern CPUs, and the frame rate scaling from 1080p to 1440p (283.5 to 256.4 FPS) is small, suggesting the CPU is the primary limiter.

Q: What is the best resolution for this combo?

A: 1440p High is the sweet spot, delivering 188.7 FPS. This is above the refresh rate of most high-refresh monitors and avoids the CPU-bound penalty seen at lower resolutions. At 4K High, the combo still produces 119.5 FPS, which is playable, but the 1440p experience is smoother.

Q: How does the Ultra preset affect performance?

A: Severely. At 1440p Ultra, the frame rate drops to 118.5 FPS, a 37% reduction from High. At 1080p Ultra, it drops to 166.9 FPS, a 33% reduction from High. The Ultra preset appears to introduce CPU-intensive effects that the Ryzen 5 3600 struggles to process.

Q: Is the RTX 4080 SUPER’s 16 GB VRAM sufficient for this game?

A: Yes. The 16 GB GDDR6X memory is more than enough for any resolution in Downfall. The GPU’s memory bandwidth of 736.3 GB/s ensures no bandwidth limitations, even at 4K Ultra, where the frame rate drops to 75.4 FPS due to rendering load, not VRAM capacity.

Q: How does this combo rank against all tested combinations?

A: It ranks 233rd out of 1741 combos, placing it in the top 13.4%. This is a strong result, but the CPU’s age prevents it from reaching the top tier. The GPU’s rival, the RTX 5070 Ti, has a 2.9% lower average benchmark score, but a newer CPU would likely push this combo higher.

Q: Should I use Low settings for competitive play?

A: The data suggests no need. At 1080p High, the combo achieves 250.1 FPS, which is only 12% lower than Low’s 283.5 FPS. The visual improvement from High is significant, and the frame rate is still high enough for any competitive scenario.

Measured FPS Breakdown

The measured FPS data reveals consistent patterns across resolutions and settings. At 1920x1080, the average frame rates are 283.5 (Low), 268.6 (Medium), 250.1 (High), and 166.9 (Ultra). The gap between Low and High is 33.4 FPS, while the drop from High to Ultra is a substantial 83.2 FPS. This indicates that the Ultra preset is particularly punishing for the CPU.

At 2560x1440, the scores are 256.4 (Low), 231.6 (Medium), 188.7 (High), and 118.5 (Ultra). The scaling from Low to High is a 26% reduction, while High to Ultra is a 37% reduction. This suggests that the CPU bottleneck becomes more pronounced at higher settings, even as resolution increases.

At 3840x2160, the scores are 175.1 (Low), 146.8 (Medium), 119.5 (High), and 75.4 (Ultra). The drop from Low to High is 32%, and High to Ultra is 37%. At this resolution, the GPU is more involved, but the Ultra preset still causes a severe frame rate collapse, indicating a combined CPU/GPU strain.

The overall pattern shows that the combo is most efficient at High settings, where the frame rate remains above 100 FPS at all resolutions. The Low and Medium presets offer diminishing returns in terms of playability, while the Ultra preset is only viable at 1080p, where it still achieves 166.9 FPS.

CPU Role

The Ryzen 5 3600 is a 6-core, 12-thread processor based on the Zen 2 architecture, running at a base clock of 3.60 GHz and a boost clock of 4.20 GHz. Its 3DMark multi-thread score of 4605 and single-thread score of 696 indicate that it is a competent mid-range CPU, but it is outclassed by newer processors. The CPU’s nearest rivals include the Intel Core i5-11400 (-0.1% delta) and the AMD Ryzen 5 7535HS (+0.2% delta), showing that it sits in a crowded performance tier.

In Downfall, the CPU’s role is to feed the GPU with draw calls and physics calculations. The data suggests that at 1080p, the CPU is the limiting factor, as frame rates do not scale proportionally with the GPU’s capabilities. The CPU’s L3 cache of 32 MB and dual-channel DDR4 memory bandwidth of 51.2 GB/s are sufficient, but the architecture’s age shows in the Ultra preset’s performance drop.

The CPU’s Cinebench R23 multi-core score of 15045 is respectable, but it pales in comparison to modern 8-core processors. This explains why the combo ranks 233rd overall, as systems with newer CPUs can extract more performance from the RTX 4080 SUPER. The CPU’s boost clock of 4.20 GHz is adequate, but the single-thread performance (3DMark single-thread score of 696) is a limiting factor in a game like Downfall, which may rely heavily on a single main thread for physics and AI calculations.
