Downfall

The AMD Ryzen 5 3600 paired with the NVIDIA GeForce RTX 5090 D presents a stark contrast in generational capability within the horror title Downfall. The data indicates a configuration where a 2019-era mainstream CPU is tasked with feeding a flagship 2025 GPU, a pairing that yields surprisingly playable results but exposes a clear bottleneck as resolution scales downward. The measured frames per second (FPS) across the three tested resolutions and four quality presets provide a comprehensive look at how this combination behaves under load.

Resolution Scaling

The FPS progression from 1920x1080 to 3840x2160 reveals a classic pattern of GPU-bound behavior, yet the magnitude of the drops is tempered by the CPU's limitations. At High settings, the average FPS moves from 248 at 1080p to 222 at 1440p, a modest 26 FPS decline, before settling at 144 at 4K. This transition from 1440p to 4K represents a 35.1% reduction in frame rate, which is substantial but indicates that the RTX 5090 D is still flexing its computational muscle at the higher resolution. However, the smaller delta between 1080p and 1440p (a 10.5% drop) suggests that the Ryzen 5 3600 is already limiting the output at the lower resolution, preventing the GPU from achieving its full potential.

The Low settings preset tells a similar story with higher absolute numbers. The 1080p Low result of 286 FPS only climbs to 256 at 1440p and then falls to 214 at 4K. The 1080p to 1440p drop is a mere 10.5%, nearly identical to the High preset, which is a strong indicator of a CPU bottleneck at these lower resolutions. The GPU is capable of far more, but the processor's 6 cores and 12 threads cannot issue draw calls fast enough to saturate the RTX 5090 D. The 4K Low result of 214 FPS shows that even at 4K, the system is not fully GPU-bound, as a flagship card would typically produce higher numbers on Low settings in a 2016 title.

Ultra settings provide the most dramatic scaling curve. At 1080p Ultra, the system delivers 202 FPS, which drops to 144 at 1440p (a 28.7% reduction) and then plummets to 90 at 4K (a 37.5% reduction from 1440p). This steeper decline at higher resolutions and settings indicates that the game's visual effects are finally overwhelming the GPU, shifting the bottleneck back toward the graphics card. The 4K Ultra result of 90 FPS is the clearest evidence of the RTX 5090 D's workload, as it represents the most demanding configuration tested. The data shows that the limiting component is resolution-dependent: at 1080p and 1440p, the Ryzen 5 3600 holds the system back, while at 4K, particularly with Ultra settings, the GPU becomes the primary constraint.

CPU Role

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor based on the Zen 2 architecture, codenamed Matisse. It operates with a base clock of 3.60 GHz and a boost clock of 4.20 GHz, and its 32 MB of shared L3 cache is a key feature for gaming performance. The CPU's benchmark results show a single-thread score of 696 in 3dmark and a multi-thread score of 4605 in the 16-thread test, placing it at the 71st percentile among all CPUs. This is a solid mid-range processor, but it is clearly outclassed by the GPU it is paired with.

In Downfall, the CPU's role becomes apparent when examining the FPS ceilings at lower resolutions. The 1080p High result of 248 FPS and the Low result of 286 FPS are strong numbers, but they are not exceptional for a combination of this GPU's raw power. The Ryzen 5 3600's nearest rivals in terms of average benchmark score include the Intel Core i7-1260P and the Intel Core i5-11400, with delta percentages of 0.2% and -0.2%, respectively. This indicates that the CPU is performing exactly as expected for its class, but that class is not sufficient to keep up with the RTX 5090 D at 1080p.

The data suggests that the CPU is the primary bottleneck at 1080p and 1440p, as evidenced by the relatively small FPS gains when moving from High to Low settings. At 1440p, the High preset yields 222 FPS, while Low yields 256 FPS, a difference of only 34 FPS. This compression of results indicates that the processor is limiting the frame rate, as a GPU-bound system would show a larger spread between settings. The Cinebench R23 multi-core score of 15045 and the Passmark multi-thread score of 17700 further confirm that the Ryzen 5 3600 is a capable mainstream chip, but it lacks the headroom required to fully feed a 104.8 TFLOPS GPU. The 3dmark 2-thread score of 1361 versus the 16-thread score of 4605 shows that scaling is decent, but the single-thread performance of 696 is a limiting factor for frame generation in CPU-bound scenarios.

GPU Role

The NVIDIA GeForce RTX 5090 D is the dominant component in this pairing, featuring the GB202 chip on the Blackwell 2.0 architecture. It boasts 32 GB of GDDR7 memory on a 512-bit bus, providing a massive 1.79 TB/s of bandwidth. The GPU's clocks are set at a base of 2017 MHz with a boost of 2407 MHz, and it contains 21,760 shading units, 680 TMUs, and 176 ROPs. This hardware configuration is designed for extreme throughput, as evidenced by its FP32 performance of 104.8 TFLOPS and its pixel rate of 423.6 GPixel/s.

In Downfall, the GPU's role is most visible at 4K resolution, where its raw power is finally utilized. The 4K High result of 144 FPS is impressive for a horror title, and the 4K Medium result of 175 FPS (with a minimum of 149 FPS and a maximum of 202 FPS) shows consistent frame delivery. The 4K Low result of 214 FPS demonstrates that even at the highest resolution, the GPU has massive headroom when settings are reduced. However, the GPU's performance is consistently held back by the CPU at lower resolutions. The 1080p Ultra result of 202 FPS is lower than the 4K Low result of 214 FPS, which is a clear sign that the processor is the limiting factor in the former scenario.

The RTX 5090 D's benchmark scores place it at the 92nd percentile among all GPUs, with an average score of 77712. Its nearest rivals include the AMD Radeon RX 6850M XT (1.6% lower) and the NVIDIA Tesla P100 PCIe 16 GB (2.4% lower), but these are mobile or datacenter parts that do not reflect the desktop gaming market. The GPU's Passmark G3D score of 44065 and DirectX 12 score of 219 indicate strong API performance, but the CPU bottleneck prevents these scores from translating into proportional FPS gains at 1080p. The data shows that the GPU is capable of far more than the system delivers, and the 4K Ultra result of 90 FPS is the only configuration where the GPU is clearly the limiting component, as the high settings demand more shading and texture operations than the CPU can feed.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across resolutions and settings. At 1920x1080, the system delivers 286 FPS on Low, 266 FPS on Medium, 248 FPS on High, and 202 FPS on Ultra. The Medium preset shows a minimum of 226 FPS and a maximum of 306 FPS, indicating a wide variance in frame times. The spread from Low to Ultra is 84 FPS, which is relatively narrow, reinforcing the CPU-bound nature of the system at this resolution. The 1080p results are all above 200 FPS, making this resolution ideal for high-refresh-rate monitors, but the data suggests that the Ryzen 5 3600 is holding the RTX 5090 D back from reaching its full potential.

At 2560x1440, the FPS figures are 256 on Low, 238 on Medium, 222 on High, and 144 on Ultra. The Medium preset shows a minimum of 202 FPS and a maximum of 274 FPS, with the average of 238 FPS representing a 10.5% drop from the 1080p Medium result. The Ultra preset at 1440p is a significant outlier, dropping 35.1% from the High preset, which suggests that the Ultra settings introduce effects that are more demanding on the GPU. This resolution still delivers high frame rates, but the gap between Low and Ultra is now 112 FPS, showing that the GPU is starting to become more relevant as the resolution increases.

At 3840x2160, the results are 214 FPS on Low, 175 FPS on Medium, 144 FPS on High, and 90 FPS on Ultra. The Medium preset provides the only min/max data for 4K, with a minimum of 149 FPS and a maximum of 202 FPS. The 4K Ultra result of 90 FPS is the lowest measured score, and it represents a 37.5% drop from the 1440p Ultra result. This is the clearest indication of the GPU being the bottleneck, as the higher resolution and settings overwhelm the RTX 5090 D's capabilities relative to the CPU. The progression from Low to Ultra at 4K shows a 124 FPS spread, the largest of any resolution, which confirms that the GPU is the primary constraint at this level.
