Downfall

Resolution Scaling

The measured FPS data for Downfall with the AMD Ryzen 5 3600 and AMD Radeon RX 6600 reveals a clear pattern of GPU-bound scaling as resolution increases. At 1080p with Low settings, the combo produces 178 FPS, which drops to 122.3 FPS at 1440p and 79.4 FPS at 4K. That represents a 31% reduction when moving from 1080p to 1440p, and a further 35% reduction from 1440p to 4K. This steep decline indicates that pixel throughput becomes the dominant constraint at higher resolutions.

The scaling behavior changes noticeably when examining the Medium preset. At 1080p, the system delivers 142.4 FPS, falling to 104 FPS at 1440p and 61.8 FPS at 4K. The gap between 1440p and 4K here is larger proportionally than the gap between 1080p and 1440p, suggesting the RX 6600's 128-bit memory bus and 224.0 GB/s bandwidth begin to struggle as the pixel count approaches 8.3 million. The High preset follows a similar trajectory: 114.5 FPS at 1080p, 82 FPS at 1440p, and 51.9 FPS at 4K.

Ultra settings expose the most dramatic resolution sensitivity. The system manages 74.6 FPS at 1080p, but this collapses to 50.7 FPS at 1440p and 33.4 FPS at 4K. The 4K Ultra result is barely playable for a horror title where responsiveness matters. Interestingly, the scaling from 1080p to 1440p at Ultra shows a 32% drop, nearly identical to the Low preset's drop, indicating that the GPU's compute resources are saturated regardless of quality level. The data suggests that for smooth 4K experiences, users should stick to Low or Medium settings, while 1440p High represents a reasonable balance for this hardware combination.

GPU Role

The AMD Radeon RX 6600 sits in the 69th percentile of all GPUs according to the benchmark database, with an average benchmark score of 25235. Its nearest rivals include the AMD Radeon 890M (deltaPct 0%), the AMD Radeon RX 580 2048SP (deltaPct -0.2%), the AMD Radeon RX 6700M (deltaPct 0.2%), and the NVIDIA GeForce RTX 3060 Ti (deltaPct 0.5%). These minuscule percentage differences indicate that the RX 6600 performs almost identically to its closest competitors in synthetic workloads, though real-world gaming results can vary.

The GPU's memory configuration plays a critical role in Downfall's performance. With 8 GB of GDDR6 memory on a 128-bit bus, the card delivers 224.0 GB/s of bandwidth. This proves sufficient for 1080p and 1440p gaming, but the 4K Ultra result of 33.4 FPS suggests that the memory subsystem becomes a limiting factor. The 14 Gbps effective memory speed and 1750 MHz memory clock are modest by current standards, and the pixel rate of 159.4 GPixel/s combined with a texture rate of 279.0 GTexel/s explains why Ultra settings at 4K push the card to its limits.

Clock speeds are another important consideration. The RX 6600 has a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. The boost behavior helps maintain frame rates in less demanding scenes, but Downfall's horror atmosphere often involves dark environments with dynamic lighting, which can cause clock fluctuations. The card's 1792 shading units and 64 ROPs provide adequate raw compute for this title, as evidenced by the 178 FPS result at 1080p Low. The 132 W TDP and single 8-pin power connector suggest the card is not power-limited in this scenario, allowing it to sustain boost clocks during extended play sessions.
