Downfall

# Downfall with AMD Ryzen 5 5600 + AMD Radeon RX 7900 XTX

The AMD Radeon RX 7900 XTX paired with the AMD Ryzen 5 5600 delivers a compelling 1440p experience in Downfall, with benchmark results showing this combination ranks 261st out of 1,741 tested hardware configurations. The GPU sits in the 85th percentile of all graphics cards, while the CPU holds the 79th percentile among all processors, indicating a balanced pairing where the graphics card leads performance. The measured frame rates across resolutions and settings reveal a system that is firmly GPU-bound at higher resolutions, with CPU limitations becoming apparent only at 1080p with lower graphical presets.

Resolution Scaling

The transition from 1080p to 4K produces dramatic frame rate reductions that clearly identify the GPU as the limiting component. At High settings, the average frame rate drops from 244.6 FPS at 1920x1080 to 174.1 FPS at 2560x1440, a reduction of approximately 29%. Moving further to 3840x2160, the frame rate falls to 107.7 FPS, representing a 56% decline from the 1080p baseline. This scaling pattern is consistent with a graphics-bound workload where pixel count increases disproportionately affect performance.

Low settings show even more pronounced scaling behavior, with 359.8 FPS at 1080p dropping to 255.9 FPS at 1440p and then to 158.4 FPS at 4K. The 4K result at Low settings is still respectable, but the 56% reduction from 1080p to 4K indicates that even at minimal graphical loads, the GPU is doing substantial work. Medium settings follow a similar trajectory: 294.2 FPS at 1080p, 210 FPS at 1440p, and 134.2 FPS at 4K — a 54% drop across the resolution range.

Ultra settings exhibit the steepest scaling curve. The 149.5 FPS at 1080p falls to 105.3 FPS at 1440p and then to 66.8 FPS at 4K, a 55% reduction from 1080p to 4K. The fact that all four settings presets show near-identical percentage drops between 1080p and 4K (ranging from 54% to 56%) strongly suggests the rendering pipeline is consistently GPU-limited across the entire settings spectrum. The RX 7900 XTX with its 24 GB of GDDR6 memory and 960.0 GB/s bandwidth never appears to hit a memory capacity ceiling, as the scaling remains smooth and predictable.

GPU Role

The Radeon RX 7900 XTX operates as the primary performance driver in this configuration, and its specifications explain the observed results. Built on the RDNA 3.0 architecture with the Navi 31 chip, the GPU features 6,144 shading units, 384 texture mapping units, and 192 raster operation pipelines. The boost clock of 2,498 MHz, game clock of 2,365 MHz, and base clock of 1,929 MHz provide the computational throughput necessary for the frame rates measured.

The 24 GB of GDDR6 memory on a 384-bit bus delivers 960.0 GB/s of bandwidth, which proves sufficient for Downfall's demands at all tested resolutions. Even at 4K Ultra settings, where the frame rate drops to 66.8 FPS, there is no evidence of memory-related stuttering or bandwidth starvation. The GPU's FP32 performance of 61.39 TFLOPS and texture rate of 959.2 GTexel/s provide ample headroom for the horror game's rendering requirements.

The GPU's benchmark scores place it in the 85th percentile of all graphics cards, with an average benchmark score of 44,019. Its nearest rivals include the NVIDIA GeForce RTX 4070 Ti, which trails by 2% in average score, and the NVIDIA GeForce RTX 4090 Mobile, which the RX 7900 XTX leads by 0.8%. The AMD Radeon Pro 580 sits 0.4% ahead, while the NVIDIA Quadro M6000 trails by 1.6%. These competitive positioning data points confirm that the GPU is a high-end part capable of driving the frame rates observed.

Settings Recommendations

The measured data indicates that High settings at 1440p offer the optimal balance of visual quality and performance. At 2560x1440, the High preset achieves 174.1 FPS, which is comfortably above display refresh rates for most monitors while maintaining substantial headroom. The Medium preset at the same resolution delivers 210 FPS, but the visual quality reduction may not justify the 36 FPS gain when High is already well above smoothness thresholds.

For 4K gaming, High settings at 107.7 FPS provide the most playable experience, as the Ultra preset drops to 66.8 FPS and may feel less responsive in a horror title where quick reactions matter. The Low preset at 4K reaches 158.4 FPS, but the graphical compromises are substantial. At 1080p, High settings at 244.6 FPS are essentially wasted performance unless paired with a very high refresh rate display; Medium at 294.2 FPS or Low at 359.8 FPS would only serve specialized competitive scenarios.

The scaling data suggests that High settings provide the most consistent experience across all three resolutions. The percentage drop from 1080p to 4K at High settings is 56%, which matches the overall pattern, but the absolute frame rates remain playable at every resolution. At Ultra settings, the 4K result of 66.8 FPS is the only measurement that dips below the 100 FPS threshold, indicating that this preset is best reserved for 1080p and 1440p use.

Measured FPS Breakdown

At 1920x1080, the RX 7900 XTX produces extremely high frame rates across all presets. Low settings deliver 359.8 FPS average, Medium settings reach 294.2 FPS, High settings achieve 244.6 FPS, and Ultra settings still manage 149.5 FPS. These numbers indicate that at 1080p, the GPU is rarely the limiting factor, and the CPU's role becomes more significant.

Moving to 2560x1440, the frame rates remain strong but show the expected decline. Low settings produce 255.9 FPS, Medium settings deliver 210 FPS, High settings achieve 174.1 FPS, and Ultra settings drop to 105.3 FPS. The 1440p results demonstrate that this combination is well-suited for high-refresh-rate gaming at this resolution, with even Ultra settings maintaining triple-digit frame rates.

At 3840x2160, the GPU's workload increases substantially. Low settings deliver 158.4 FPS, Medium settings reach 134.2 FPS, High settings achieve 107.7 FPS, and Ultra settings fall to 66.8 FPS. The 4K results show that High settings remain the sweet spot, offering playable performance without the steep cost of Ultra. The progression from Low to Ultra at 4K shows a consistent decline: 158.4 to 134.2 to 107.7 to 66.8, representing drops of 15%, 20%, and 38% respectively as settings increase.

CPU Role

The AMD Ryzen 5 5600 provides the computational foundation for this gaming configuration, and its specifications help explain the performance ceiling observed at lower resolutions. With 6 cores and 12 threads based on the Zen 3 architecture, the CPU operates at a base clock of 3.50 GHz and a boost clock of 4.40 GHz. The 32 MB of shared L3 cache and 51.2 GB/s memory bandwidth support the GPU's data demands effectively.

The CPU's benchmark results place it in the 79th percentile of all processors, with an average benchmark score of 21,765. Its nearest rivals include the Intel Xeon D-1746TER, which trails by 0.6%, and the AMD EPYC 9554P, which leads by 0.6%. The Intel Core i7-11700F sits 0.9% ahead in average score, while the AMD EPYC 9534 is 0.6% behind. These competitive positions indicate that the Ryzen 5 5600 is a solid mid-range processor that does not bottleneck the RX 7900 XTX in most scenarios.

The single-thread performance of 882 in 3DMark and 2,584 in Cinebench R23 suggests adequate per-core performance for gaming workloads. Multi-threaded results, including 18,309 in Cinebench R23 multicore and 21,541 in PassMark multithread, demonstrate that the CPU can handle background tasks while gaming. At 1080p with Low settings, the 359.8 FPS result likely approaches the CPU's frame generation limit, but at higher resolutions and settings, the GPU becomes the definitive bottleneck. The CPU's 65 W TDP and 7 nm process node contribute to efficient operation without thermal throttling concerns that could impact sustained gaming performance.
