Downfall

Downfall’s measured performance on the AMD Ryzen 7 9800X3D and NVIDIA GeForce RTX 3080 combination reveals a configuration that is heavily dependent on graphics settings and resolution. The data indicates a system capable of delivering high refresh rates at lower resolutions, but one that becomes increasingly GPU-bound as pixel count and graphical fidelity rise. The RTX 3080, positioned at the 80th percentile among all GPUs, demonstrates its strengths and limitations across the four tested settings presets, while the Ryzen 7 9800X3D, sitting at the 90th percentile for CPUs, provides a robust foundation that rarely bottlenecks the frame output.

Resolution Scaling

The frame rate progression from 1080p to 4K clearly illustrates the shifting bottleneck in this pairing. At 1920x1080 with Low settings, the combination produces an average of 301.4 FPS, which drops to 215 FPS at 2560x1440 and further to 135.3 FPS at 3840x2160. This represents a 55.1% reduction in frame rate when moving from 1080p to 4K at Low settings, indicating that even at the lowest graphical load, the GPU is still the primary limiting factor. The CPU, with its 8 cores and 16 threads based on Zen 5 architecture, is clearly capable of feeding the GPU at these high frame rates, as evidenced by the triple-digit scores at lower resolutions.

The scaling pattern changes dramatically with Ultra settings. At 1920x1080 Ultra, the average FPS is 128.8, which falls to 90.2 FPS at 2560x1440 and 58.8 FPS at 3840x2160. The drop from 1080p to 4K at Ultra is 54.4%, nearly identical to the Low setting reduction. However, the absolute values tell a more important story: the 4K Ultra result of 58.8 FPS is only 19.5% of the 1080p Low result of 301.4 FPS. This massive spread, over 5x difference, confirms that the RTX 3080's rendering workload scales enormously with settings, while the CPU overhead remains relatively constant.

At High settings, the resolution scaling shows a similar trend, with 203.6 FPS at 1080p, 142.4 FPS at 1440p, and 88.6 FPS at 4K. The 4K High result is 43.5% of the 1080p High result, suggesting that the GPU's memory bandwidth of 760.3 GB/s and its 10 GB of GDDR6X memory become strained at higher resolutions. The Medium settings preset follows the established pattern, delivering 247.2 FPS at 1080p, 173.6 FPS at 1440p, and 106.8 FPS at 4K. The fact that 4K Medium (106.8 FPS) outperforms 1080p Ultra (128.8 FPS) by a smaller margin than expected highlights how the Ultra preset introduces rendering features that disproportionately impact the GPU.

GPU Role

The NVIDIA GeForce RTX 3080, built on the Ampere architecture with the GA102 chip, is the clear performance limiter in this configuration for Downfall. With a boost clock of 1710 MHz and a base clock of 1440 MHz, the GPU leverages its 8704 shading units to process the game's horror environments. The 10 GB of GDDR6X memory on a 320-bit bus provides 760.3 GB/s of bandwidth, which proves adequate for 1080p and 1440p gaming but shows strain at 4K with higher settings. The measured data reflects this, with the gap between Low and Ultra settings widening from 172.6 FPS at 1080p to 76.5 FPS at 4K.

The GPU's 80th percentile ranking places it above the AMD Radeon 880M (0.4% lower score) and slightly below the AMD Radeon RX 7900 GRE (0.9% higher score). In practice, this means the RTX 3080 delivers competitive performance in its class, though it is not a top-tier card by modern standards. The memory configuration is particularly relevant for Downfall's Ultra settings, where the 4K result of 58.8 FPS suggests the GPU is hitting both compute and memory bandwidth limits. At lower settings, the GPU's 29.77 TFLOPS FP32 performance allows for high frame rates, but the scaling from Medium to Ultra shows diminishing returns as more complex rendering features engage.

The GPU's 272 texture mapping units and 96 ROPs contribute to its pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s. These specifications explain why the card handles 1440p High (142.4 FPS) so effectively, as the texture and pixel throughput are sufficient for that workload. However, the 4K Ultra result indicates that the GPU's fillrate capabilities are not enough for the most demanding scenarios, reinforcing the conclusion that the RTX 3080 is best suited for 1440p gaming with this CPU.

Measured FPS Breakdown

At 1920x1080, the data shows a clear hierarchy across settings. Low settings deliver 301.4 FPS, Medium produces 247.2 FPS, High achieves 203.6 FPS, and Ultra drops to 128.8 FPS. The transition from Low to Medium costs 54.2 FPS, while moving from High to Ultra costs 74.8 FPS, indicating that the Ultra preset imposes a significant additional load on the GPU. This 1080p resolution is where the CPU's capabilities are most visible, as the 8-core, 16-thread Ryzen 7 9800X3D with its 5.20 GHz boost clock can easily sustain these frame rates without becoming a bottleneck.

Moving to 2560x1440, the performance scales down proportionally. Low settings yield 215 FPS, Medium delivers 173.6 FPS, High produces 142.4 FPS, and Ultra falls to 90.2 FPS. The 1440p results show a more compressed range than 1080p, with a 124.8 FPS difference between Low and Ultra, compared to 172.6 FPS at 1080p. This compression suggests that the GPU is starting to become the dominant factor, as the CPU's ability to feed frames becomes less critical when the GPU takes longer to render each one. The 1440p Ultra result of 90.2 FPS is particularly notable, as it remains above the 60 FPS threshold while providing a significantly higher visual quality than the 1080p Ultra setting.

At 3840x2160, the GPU's limitations become most apparent. Low settings produce 135.3 FPS, Medium delivers 106.8 FPS, High achieves 88.6 FPS, and Ultra drops to 58.8 FPS. The 4K results show a 76.5 FPS spread between Low and Ultra, which is the smallest range of any resolution. This narrowing indicates that at 4K, even Low settings require substantial GPU resources, leaving less headroom for settings to impact performance. The 4K Ultra result of 58.8 FPS is the only measured configuration that fails to reach 60 FPS, demonstrating the RTX 3080's struggle with the most demanding scenarios. The combination of the GPU's 10 GB memory capacity and 760.3 GB/s bandwidth appears to be a limiting factor at this resolution, particularly with the Ultra preset's higher texture and shading requirements.

CPU Role

The AMD Ryzen 7 9800X3D, with its 8 cores and 16 threads based on the Zen 5 architecture, provides ample processing power for Downfall. The CPU's base clock of 4.70 GHz and boost clock of 5.20 GHz, combined with 96 MB of shared L3 cache, ensure that it can handle the game's logic and AI calculations without becoming a limiting factor. The CPU's benchmark results reinforce this assessment, with a Cinebench R23 multi-core score of 34004 and a single-core score of 4800, placing it at the 90th percentile among all CPUs.

The CPU's nearest rivals in benchmark scores include the Intel Xeon 6353P (0.1% lower score) and the Intel Core Ultra 5 225 (0.1% lower score), indicating that the Ryzen 7 9800X3D is competitive with other high-end processors. In the context of Downfall's measured FPS, the CPU's role is most evident at 1080p Low settings, where the 301.4 FPS result shows that the processor can sustain extremely high frame rates without bottlenecking. The 3DMark single-thread score of 1212 and multi-thread score of 10067 demonstrate the CPU's balanced performance profile, which is well-suited for a horror game that may feature both single-threaded scripting and multi-threaded physics.

The CPU's memory support for DDR5 with dual-channel configuration provides 89.6 GB/s of memory bandwidth, which pairs well with the GPU's 760.3 GB/s bandwidth. This memory subsystem ensures that data can flow efficiently between the CPU and GPU, minimizing potential stutters or frame hitches. The Ryzen 7 9800X3D's 120 W TDP and 4 nm process node from TSMC contribute to its efficiency, allowing it to maintain high boost clocks during extended gaming sessions. Overall, the CPU's performance is more than sufficient for Downfall, with the data showing that the RTX 3080 is the definitive bottleneck in this pairing, particularly at 4K Ultra settings.
