Downfall

# Downfall with AMD Ryzen 5 5600GT + AMD Radeon RX 6600

The measured frame rates for this pairing in Downfall reveal a system that scales predictably with resolution changes, but the relationship between settings and performance is anything but linear. The AMD Ryzen 5 5600GT, a 6-core Zen 3 part, and the AMD Radeon RX 6600, an RDNA 2.0 GPU with 8 GB of GDDR6 memory, produce a range of results that suggest the GPU becomes the primary constraint as resolution climbs. The data shows a 176.2 FPS average at 1080p Low, which drops to 35.4 FPS at 4K Ultra — a gap of roughly 5x that points to shifting bottlenecks across the tested configurations.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial, but the magnitude varies dramatically depending on the preset. At Low settings, the transition from 1920x1080 (176.2 FPS) to 3840x2160 (77.1 FPS) represents a 56% reduction in average frame rate. That is a steep decline, yet it still leaves the game playable at 4K on the lowest preset. Moving to Medium settings, the scaling is similar in percentage terms: 143.4 FPS at 1080p falls to 63.9 FPS at 4K, a 55% drop. High settings show 115.4 FPS at 1080p versus 52.8 FPS at 4K, a 54% reduction. Ultra is where the bottom falls out — 74 FPS at 1080p collapses to 35.4 FPS at 4K, a 52% loss that pushes the experience below the 60 FPS threshold even at the starting resolution.

What these numbers imply is a GPU-limited scenario at higher resolutions. The RX 6600's 8 GB frame buffer and 224.0 GB/s memory bandwidth are being taxed heavily as pixel count increases. The consistent ~50-56% penalty across all presets when moving from 1080p to 4K suggests that the render resolution, not the complexity of the scene, is the dominant factor. The 2560x1440 results sit neatly between the extremes: 125.8 FPS on Low, 100.9 FPS on Medium, 85 FPS on High, and 51.9 FPS on Ultra. The 1440p to 4K transition is steeper in raw FPS terms for every preset, which aligns with the 2.25x pixel count increase versus the 1.78x jump from 1080p to 1440p.

GPU Role

The RX 6600's specifications explain much of the observed behavior. Its boost clock of 2491 MHz and game clock of 2044 MHz are the primary drivers of raw throughput, but the 8 GB GDDR6 memory on a 128-bit bus with 224.0 GB/s bandwidth is the likely ceiling at 4K. The GPU's 1792 shading units and 64 ROPs deliver a pixel rate of 159.4 GPixel/s, yet the Ultra preset at 4K still only manages 35.4 FPS. This indicates that the memory subsystem, not the compute units, is the limiting factor at extreme resolutions.

The Vulkan score of 80492 and DirectX 12 score of 51 in Passmark suggest the GPU's API support is solid — it lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 — but Downfall's engine appears to favor lower presets regardless. The difference between Low and Ultra at 1080p is 102.2 FPS (176.2 vs 74), which is a 58% performance swing. This is a larger relative gap than the resolution scaling itself, indicating that the game's Ultra preset introduces effects that disproportionately burden the GPU. The 28 ray tracing cores on the RX 6600 do not appear to help in this title, as the Ultra preset results are consistently the weakest across all resolutions.

How This Combo Ranks

The combo rank of 1386 out of 1741 tested combinations places this pairing in the lower percentile of systems evaluated. This ranking reflects that the CPU, while competent with an average benchmark score of 20740, and the GPU, with an average score of 25235, are both mid-tier parts that do not synergize into a top-tier gaming experience. The CPU's percentile of 78 among all processors is respectable, and the GPU's percentile of 69 is similar, but the combination rank suggests that other pairings achieve better frame rates in Downfall.

The CPU's nearest rivals show how close the 5600GT is to its competition. The Intel Core i7-10700 scores 20746, a 0% delta, meaning the 5600GT at 20740 is essentially identical. The AMD Ryzen 5 5600X scores 20680, a 0.3% delta, putting the 5600GT slightly ahead. The Intel Core i5-12490F scores 20794, a -0.3% delta, meaning the 5600GT is marginally behind. The AMD EPYC 7J13 scores 20845, a -0.5% delta. These differences are negligible for gaming, confirming that the CPU is not the bottleneck in this pairing. The GPU side shows similar clustering: the AMD Radeon 890M scores 25246 (0% delta), the RX 580 2048SP scores 25287 (-0.2% delta), the RX 6700M scores 25180 (0.2% delta), and the RTX 3060 Ti scores 25120 (0.5% delta). The RX 6600 at 25235 sits squarely in the middle of this pack.

Settings Recommendations

The measured data offers a clear hierarchy for playable settings. At 1080p, the Low preset delivers 176.2 FPS, which is far beyond what a 60 Hz display needs and even exceeds 144 Hz refresh rates. Medium at 143.4 FPS is still excellent, and High at 115.4 FPS remains smooth. Ultra at 74 FPS is playable but represents a 36% drop from High, which is a steep price for the visual upgrade. The 1440p results follow a similar pattern: Low at 125.8 FPS is ideal for high-refresh monitors, Medium at 100.9 FPS is strong, High at 85 FPS is acceptable, and Ultra at 51.9 FPS dips below 60 FPS. At 4K, only Low at 77.1 FPS and Medium at 63.9 FPS clear the 60 FPS bar; High at 52.8 FPS and Ultra at 35.4 FPS do not.

The data suggests that the High preset is the sweet spot for 1080p and 1440p gaming, offering a balanced experience without the heavy cost of Ultra. For 4K, Medium is the maximum viable setting, and Low is the only preset that provides comfortable headroom above 60 FPS. The gap between Medium and High at every resolution is consistent — roughly 18% at 1080p (143.4 vs 115.4), 16% at 1440p (100.9 vs 85), and 17% at 4K (63.9 vs 52.8) — making High a moderate upgrade rather than a transformative one.

Measured FPS Breakdown

At 1920x1080, the full range of presets shows this system's capability: Low averages 176.2 FPS, Medium averages 143.4 FPS, High averages 115.4 FPS, and Ultra averages 74 FPS. The spread of 102.2 FPS between Low and Ultra is the largest of any resolution, indicating that at 1080p, the CPU and GPU have enough headroom to reflect the full cost of each preset.

At 2560x1440, the averages are 125.8 FPS for Low, 100.9 FPS for Medium, 85 FPS for High, and 51.9 FPS for Ultra. The delta between Low and Ultra is 73.9 FPS, smaller than at 1080p, which signals that the GPU is starting to limit the upper presets more severely. The 51.9 FPS Ultra result is the first below-60 FPS reading at this resolution.

At 3840x2160, the results compress further: Low averages 77.1 FPS, Medium averages 63.9 FPS, High averages 52.8 FPS, and Ultra averages 35.4 FPS. The Low-to-Ultra gap narrows to 41.7 FPS, and all presets except Low and Medium fall below the 60 FPS threshold. The 4K Ultra result of 35.4 FPS is less than half of the 1080p High result, underscoring the GPU's struggle at extreme resolutions.

CPU Role

The AMD Ryzen 5 5600GT's 6 cores and 12 threads, with a base clock of 3.60 GHz and boost clock of 4.60 GHz, are more than adequate for Downfall's demands. The CPU's single-thread performance, measured at 913 in 3DMark single-thread and 2438 in Cinebench R23 single-core, is strong for a 5000 series part. The multi-thread scores — 17272 in Cinebench R23 multicore and 20325 in Passmark multithread — indicate that the CPU is not creating a bottleneck in this game. The 16 MB L3 cache and 7 nm process node are competitive, and the CPU's percentile of 78 among all processors confirms its solid standing.

The real question is whether the CPU's performance ceiling is ever reached in Downfall. The measured FPS at 1080p Low (176.2 FPS) is high enough that the CPU's 12 threads are likely being fully utilized, but the consistent ~50% FPS drop from 1080p to 4K across all presets points to the GPU as the primary constraint. The CPU's nearest rivals — the Intel Core i7-10700 and AMD Ryzen 5 5600X — all score within 0.5% of the 5600GT, so any differences in gaming performance would be negligible. The 5600GT's boost clock of 4.60 GHz and Zen 3 architecture provide the single-thread strength that Downfall likely relies on, but the data shows that even at 1080p, the GPU's 2491 MHz boost clock and 8 GB memory are the components that define the experience. The CPU appears to be a capable companion that is rarely the limiting factor, which is the expected behavior for a 6-core, 12-thread processor in a horror title.
