How This Combo Ranks

The combo's rank of 313 out of 1741 tested combinations places it in the 82.0 percentile of all tested hardware pairings for Downfall. This is a strong showing, though not elite — the top 18% of combos outperform it, likely featuring newer CPUs or more balanced pairings. The rank reflects the RX 7900 XTX's enormous GPU headroom being partially constrained by the Ryzen 5 3600's Zen 2 architecture, particularly at lower resolutions. The CPU's own percentile standing of 76th among all processors suggests it is a mid-to-upper-tier chip, but the GPU's 85th percentile ranking indicates the graphics card is the more capable component in this pairing.

The nearest CPU rivals illustrate the tight competition at this performance tier. The Intel Core i5-11400 scores 18150, only 0.1% higher than the Ryzen 5 3600's 18129, while the AMD Ryzen 5 7535HS scores 18101, 0.2% lower. The AMD Ryzen 5 1600 scores 18158, 0.2% higher. These sub-1% deltas mean the CPU's performance class is densely packed, and small architectural differences translate into negligible real-world FPS variations in Downfall. For the GPU, the RX 7900 XTX's nearest rivals show more meaningful gaps: the NVIDIA GeForce RTX 4070 Ti scores 44900, which is 2.0% higher, while the AMD Radeon Pro 580 scores 44195, 0.4% lower. The 0.8% advantage over the RTX 4090 Mobile (43667) reinforces that the 7900 XTX is a top-tier desktop GPU, but the 2% deficit to the RTX 4070 Ti suggests the latter holds a slight edge in synthetic workloads.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a clear GPU-bound behavior at higher resolutions, with CPU limitations emerging at 1080p. At High settings, the transition from 1080p to 1440p reduces average FPS from 240.4 to 175.3, a 27.1% drop. Moving from 1440p to 4K further reduces FPS to 110.6, another 36.9% reduction. The cumulative drop from 1080p to 4K is 54.0%, which is substantial but not as severe as what a fully GPU-limited scenario would show, suggesting the CPU still contributes at 1080p.

At Ultra settings, the scaling pattern shifts. The 1080p Ultra result of 151.0 FPS drops to 108.1 FPS at 1440p (a 28.4% reduction), then to 65.8 FPS at 4K (a 39.1% reduction from 1440p). The 4K Ultra result is the lowest in the entire dataset, indicating that Ultra settings at 4K push the GPU to its limits, with the CPU becoming less relevant. The gap between Low and Ultra presets widens with resolution: at 1080p, the difference is 137.6 FPS (288.6 vs 151.0), while at 4K it narrows to 94.8 FPS (160.6 vs 65.8). This pattern indicates that at 1080p Low, the CPU is the limiting factor, capping frame rates near 288.6 FPS, whereas at 4K Ultra, the GPU's rendering workload dominates.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all presets. The Low preset averages 288.6 FPS, which likely approaches the CPU's maximum frame delivery capability given the 6-core/12-thread design. Medium drops to 263.5 FPS, a 8.7% reduction from Low. High settings produce 240.4 FPS, down 16.7% from Low. Ultra is the most demanding at 151.0 FPS, a 47.7% reduction from Low. These results indicate that at 1080p, the CPU's single-thread performance (evidenced by a 3dmark single-thread score of 696) becomes the bottleneck, as even the most demanding preset stays above 150 FPS.

At 2560x1440, the frame rates remain high but show the GPU's increasing workload. Low averages 255.1 FPS, only 11.6% lower than the 1080p Low result, suggesting the GPU can still saturate the CPU's output at this resolution. Medium produces 215.0 FPS, a 15.7% drop from Low. High delivers 175.3 FPS, 31.3% below Low. Ultra averages 108.1 FPS, a 57.6% reduction from Low, indicating that the combination of higher resolution and Ultra settings begins to strain the GPU. The 1440p results show a balanced system where neither component is fully saturated, though the GPU's role grows.

At 3840x2160, the GPU becomes the clear limiter. Low averages 160.6 FPS, down 37.0% from 1080p Low. Medium produces 131.2 FPS, a 18.3% drop from Low at the same resolution. High averages 110.6 FPS, down 31.1% from Low. Ultra delivers 65.8 FPS, a 59.0% reduction from Low. The 4K Ultra result is the only preset/resolution combination below 100 FPS in the entire dataset, highlighting the extreme demands of Ultra settings at 4K. The progression from Low to Ultra at 4K shows a consistent GPU-bound scaling, with each preset level adding significant rendering load.

GPU Role

The AMD Radeon RX 7900 XTX brings 24 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. This memory configuration is critical for Downfall's 4K Ultra preset, where the 65.8 FPS result still requires substantial memory throughput. The GPU's boost clock of 2498 MHz and game clock of 2365 MHz, based on a 1929 MHz base, indicate a high-frequency design that contributes to the strong 1080p and 1440p results. The 6144 shading units and 192 ROPs handle the rasterization workload, while the 96 ray accelerators provide hardware support for any ray-traced effects in the horror title.

The GPU's synthetic benchmarks confirm its high-end positioning. The 3DMark Steel Nomad DX12 score of 6841 and Geekbench Vulkan score of 192597 place it at the 85th percentile of all GPUs. The Passmark G3D score of 31238 further validates its performance, while the compute-oriented Passmark GPU Compute score of 17689 shows strong parallel processing capability. The GPU's nearest rival, the NVIDIA GeForce RTX 4070 Ti, scores 2.0% higher in average benchmark score (44900 vs 44019), yet the 7900 XTX's 24 GB memory capacity exceeds what that rival offers, which may benefit texture-heavy scenes in Downfall. The GPU's 355 W TDP and PCIe 4.0 x16 interface ensure it can sustain high clock speeds during extended gaming sessions.

In Downfall specifically, the GPU's role becomes more pronounced at 4K and with higher presets. The 4K Ultra result of 65.8 FPS is 77.2% lower than the 1080p Low result, demonstrating the GPU's workload scaling. The data shows that the RX 7900 XTX is the primary driver of frame rates above 1440p, with the CPU's influence diminishing as resolution increases. At 1080p Low, the 288.6 FPS result is likely CPU-bound, as the GPU could theoretically render faster, but the Ryzen 5 3600's 12 threads and 3.60 GHz base clock (4.20 GHz boost) cap the output. The 24 GB VRAM provides ample headroom for Downfall's textures at all presets, with no indication of memory capacity limiting performance in this title.
