Downfall

The AMD Ryzen 5 2600 and AMD Radeon RX 6650 XT combination in Downfall shows a clear pattern of GPU-bound scaling as resolution increases, with the CPU proving sufficient to keep the graphics card well-fed at lower settings. The measured data indicates that this pairing is best utilized at 1440p, where it delivers a strong balance between visual fidelity and frame rate. The benchmark results show a consistent hierarchy across all three tested resolutions, with performance scaling predictably from Low to Ultra settings.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 reveals a significant performance drop that highlights the GPU as the primary limiting factor at higher resolutions. At Low settings, the average frame rate falls from 199 FPS at 1080p to 142 FPS at 1440p, and finally to 88 FPS at 4K. This represents a 55.7% reduction in performance from 1080p to 4K, a substantial decline that suggests the RX 6650 XT's 8 GB of GDDR6 memory and 128-bit bus are being heavily taxed at the highest resolution.

The scaling pattern becomes even more pronounced at Ultra settings, where the frame rate drops from 83 FPS at 1080p to 59 FPS at 1440p and then to 37 FPS at 4K. The 4K Ultra result of 37 FPS indicates that this configuration is not viable for maximum quality at that resolution, as the frame rate falls below the 60 FPS threshold commonly considered the baseline for smooth gameplay. The gap between 1080p and 1440p results at Ultra settings (83 FPS to 59 FPS) shows a 28.9% performance loss, while the jump from 1440p to 4K (59 FPS to 37 FPS) represents a 37.3% decline, demonstrating that the memory bandwidth constraint becomes increasingly severe as pixel count rises.

Interestingly, the Medium settings row provides the only complete min/max data across all resolutions, showing a 162 FPS average at 1080p with a minimum of 138 FPS and maximum of 187 FPS. At 1440p Medium, the average drops to 116 FPS with a range of 99 to 133 FPS, while 4K Medium yields 72 FPS with a spread of 61 to 83 FPS. These figures suggest that the GPU's 280.3 GB/s memory bandwidth is the limiting factor at 4K, as the frame time variance increases disproportionately compared to the resolution scaling.

The data indicates that the Ryzen 5 2600, with its 6 cores and 12 threads running at a base clock of 3.40 GHz and boost clock of 3.90 GHz, is not the bottleneck at any resolution. The consistent performance scaling across resolutions points to the GPU being the limiting component, particularly at 4K where the RX 6650 XT's 10.79 TFLOPS FP32 compute and 168.6 GPixel/s pixel rate struggle to maintain high frame rates.

Settings Recommendations

Based on the measured frame rates, the optimal experience for this combination is at 1440p with High settings, delivering 95 FPS average. This configuration provides a significant visual quality improvement over Low settings while maintaining a frame rate well above the 60 FPS threshold. The 1440p High result of 95 FPS represents a 33% reduction from the 142 FPS achieved at Low settings, but the visual fidelity gain justifies this trade-off for most users.

For users prioritizing maximum frame rates, 1080p Low offers the highest measured performance at 199 FPS, which is ideal for competitive play or high refresh rate displays. However, the 133 FPS achieved at 1080p High provides a better balance between image quality and speed, with only a 33% performance penalty compared to Low settings. The 1080p Medium setting at 162 FPS sits between these two extremes and offers a reasonable middle ground.

At 4K resolution, the data shows that only Low settings (88 FPS) and Medium settings (72 FPS) reach playable frame rates. The High setting at 4K produces 59 FPS, which is borderline for smooth gameplay, while Ultra drops to 37 FPS, which is generally considered too low for a satisfying experience. The 4K Medium result of 72 FPS with a minimum of 61 FPS indicates that this is the highest quality setting that maintains consistent performance at this resolution.

The Ultra preset consistently delivers lower performance across all resolutions, with the 1080p Ultra result of 83 FPS being the only Ultra configuration that exceeds 60 FPS. This suggests that the Ultra preset's additional graphical features impose a significant performance cost that may not be justified given the marginal visual improvements over High settings. For this combination, High settings at 1440p represent the sweet spot, offering 95 FPS with the visual benefits of higher quality textures and effects.
