The GPU's pixel rate of 236.1 GPixel/s and texture rate of 393.4 GTexel/s provide the raw throughput needed to sustain the frame rates observed in the measured data. Floating-point performance is rated at 25.18 TFLOPS for both FP32 and FP16, indicating balanced compute capabilities.

In Downfall, the GPU's 16 GB frame buffer proves ample even at 3840x2160, where the highest preset (Ultra) still delivers playable average FPS. The RX 7700's percentile rank of 58 against all GPUs suggests it has headroom for demanding titles, and the measured data confirms this. At 4K Ultra, the combo averages 45 FPS, which is the lowest measured result. At 4K High, the average jumps to 72 FPS, showing that the GPU's compute and memory resources respond well to moderate settings reductions. The memory bandwidth of 624.1 GB/s appears sufficient for this title, as the frame rates at 1440p and 1080p scale in a manner consistent with GPU-bound workloads.

Resolution Scaling

The measured FPS data reveals a clear pattern of GPU dominance across all resolutions. At 1920x1080 with Low settings, the combo achieves 240 FPS, which drops to 171 FPS at 2560x1440 and 107 FPS at 3840x2160. This represents a 29% reduction moving from 1080p to 1440p, and a further 37% reduction from 1440p to 4K. Such scaling indicates that the GPU is the primary bottleneck, as pixel throughput requirements increase substantially with resolution.

With High settings, the progression from 161 FPS at 1080p to 115 FPS at 1440p to 72 FPS at 4K shows a 29% drop from 1080p to 1440p and a 37% drop from 1440p to 4K. The consistency of these percentage drops across Low and High settings suggests the GPU's compute resources scale linearly with resolution, with no unexpected memory or bandwidth bottlenecks emerging at higher pixel counts.

Ultra settings show the steepest absolute decline: 101 FPS at 1080p, 72 FPS at 1440p, and 45 FPS at 4K. The 29% reduction from 1080p to 1440p and 38% reduction from 1440p to 4K mirror the pattern seen in other presets. This uniform scaling behavior indicates that Downfall's rendering pipeline is consistently GPU-bound across all quality levels, with the RX 7700's 16 GB memory and 624.1 GB/s bandwidth providing sufficient resources to avoid any resolution-specific penalties.
