Downfall

The AMD Ryzen 7 5700X3D paired with the AMD Radeon RX 6600 delivers a playable experience in Downfall, but the data reveals a system that is heavily constrained by the graphics card at higher resolutions. This analysis examines the measured frame rates across 1080p, 1440p, and 4K, the distinct roles of the CPU and GPU, and provides settings recommendations based strictly on the benchmark data.

Resolution Scaling

The measured FPS data shows a clear and predictable trend: as resolution increases, average frame rates drop significantly. At 1080p with Low settings, the system achieves 175 FPS. Moving to 1440p at the same settings drops the average to 125 FPS, a reduction of 50 FPS. At 4K with Low settings, the average falls further to 78 FPS. This pattern indicates that the rendering load is scaling heavily with pixel count, which is expected for a GPU-bound scenario.

The scaling pattern becomes more telling when observing the High settings preset. At 1080p High, the average is 117 FPS. This drops to 84 FPS at 1440p High, and further down to 52 FPS at 4K High. The 4K High result is just barely above the 50 FPS threshold often considered the minimum for smooth gameplay, suggesting that the RX 6600 is reaching its limits at this resolution and preset combination.

The data strongly suggests that the limiting component at 1080p and 1440p is the GPU, not the CPU. The Ryzen 7 5700X3D, with its 8 cores and 16 threads, appears more than capable of feeding frames to the graphics card at these lower resolutions. However, the steep drop from 1080p to 4K—a 65 FPS decrease on Low settings (175 to 78) and a 65 FPS decrease on High settings (117 to 52)—points to the GPU’s pixel throughput as the primary bottleneck. The CPU’s role remains consistent, but the GPU's workload quadruples as resolution increases, causing the frame rate to plummet.

CPU Role

The AMD Ryzen 7 5700X3D is a desktop processor from the 5000 series, built on the Zen 3 architecture with the codename Vermeer. It operates on the AMD Socket AM4 platform and is manufactured on a 7 nm process node. The chip features 8 cores and 16 threads, with a base clock of 3.00 GHz and a boost clock of 4.10 GHz. Its cache configuration is substantial, featuring 64 KB of L1 cache per core, 512 KB of L2 cache per core, and a large 96 MB of shared L3 cache.

In synthetic benchmarks, this CPU demonstrates strong multi-threaded performance. It scores 22,366 in Cinebench R23 multi-core and 11,086 in Geekbench multi-core. Single-thread performance is also respectable, with a Cinebench R23 single-core score of 3,157 and a Geekbench single-core score of 1,849. These numbers place the processor in the 77th percentile against all CPUs, indicating it is a well-above-average performer.

For Downfall, a horror game, the CPU’s role is to handle game logic, physics, and AI. The data shows that at 1080p Low, the system hits 175 FPS, which is a high frame rate that would stress the CPU’s ability to issue draw calls. Given the 3DMark 16-thread score of 6,764 and the 8-thread score of 5,357, the processor has ample multi-threading headroom. The benchmark results indicate that the CPU is not the bottleneck in this configuration, as the frame rates scale down primarily with resolution, not with CPU-intensive tasks. The processor’s high L3 cache and 16 threads likely contribute to consistent frame pacing, preventing stutters even at lower resolutions where the GPU is less stressed.

GPU Role

The AMD Radeon RX 6600 is based on the RDNA 2.0 architecture and features the Navi 23 chip. It is manufactured on a 7 nm process and includes 1,792 shading units, 112 texture mapping units, and 64 render output units. The GPU operates with a base clock of 1626 MHz and a boost clock of 2491 MHz. It is equipped with 8 GB of GDDR6 memory on a 128-bit bus, providing a memory bandwidth of 224.0 GB/s.

The GPU’s compute capabilities are substantial, with an FP32 performance of 8.928 TFLOPS. In synthetic benchmarks, it scores 15,096 in Passmark G3D and 67,623 in Geekbench Vulkan. These scores place the card in the 63rd percentile against all GPUs, showing it is a mid-range performer.

In Downfall, the GPU’s role is to render the game’s visuals, including textures, lighting, and shadows. The measured FPS data shows that the GPU is the dominant factor in determining performance. At 4K Ultra, the average FPS drops to 33, which is below the playable threshold. At 1080p Ultra, the average is 73 FPS, which is playable but shows the card’s limitations at higher settings. The 8 GB VRAM capacity is likely sufficient for this game, but the GPU’s raw compute power, as indicated by its pixel rate of 159.4 GPixel/s, is the limiting factor at high resolutions. The data confirms that the RX 6600 is a capable 1080p card, but struggles to maintain high frame rates at 4K with higher quality presets.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets.

At 1920x1080, the system performs admirably:

• Low: 175 FPS average
• Medium: 143 FPS average, with a minimum of 122 FPS and a maximum of 164 FPS
• High: 117 FPS average
• Ultra: 73 FPS average

At 2560x1440, performance scales down:

• Low: 125 FPS average
• Medium: 102 FPS average, with a minimum of 87 FPS and a maximum of 117 FPS
• High: 84 FPS average
• Ultra: 52 FPS average

At 3840x2160, the GPU becomes the clear bottleneck:

• Low: 78 FPS average
• Medium: 64 FPS average, with a minimum of 54 FPS and a maximum of 73 FPS
• High: 52 FPS average
• Ultra: 33 FPS average

The data reveals that the Medium preset provides the most balanced performance, with the only recorded minimum and maximum FPS values in the dataset. At 1080p Medium, the frame rate stays between 122 and 164 FPS, indicating good consistency. At 1440p Medium, the range is 87 to 117 FPS, which is still smooth. At 4K Medium, the range tightens to 54 to 73 FPS, which is acceptable for a slower-paced horror game.

The Ultra preset is the most demanding, reducing performance by approximately half compared to High settings at every resolution. For example, at 1440p, High yields 84 FPS while Ultra yields 52 FPS, a 32 FPS drop. This suggests that Ultra settings introduce a significant rendering overhead that the RX 6600 cannot handle efficiently at higher resolutions.
