Downfall

The AMD Ryzen 7 7800X3D paired with the NVIDIA GeForce RTX 4070 Ti delivers a formidable performance profile in Downfall, a horror title that scales aggressively with both resolution and graphical presets. The measured data reveals a component pairing where the GPU is the primary scaling factor at higher resolutions, while the CPU’s substantial cache architecture ensures the system remains fluid even when frame rates exceed typical display refresh rates.

Resolution Scaling

The FPS progression from 1080p to 4K clearly illustrates the shifting bottleneck between the CPU and GPU. At 1920x1080 with Low settings, the combo achieves 366 FPS, which drops to 264.4 FPS at 2560x1440 and further to 161.8 FPS at 3840x2160. This represents a 55.8% reduction in frame rate from 1080p to 4K at Low settings, indicating that the GPU is already becoming the limiting factor even at the lowest preset.

The scaling becomes more pronounced at higher settings. With Ultra quality, the frame rate falls from 151.9 FPS at 1080p to 113 FPS at 1440p, and finally to 70.1 FPS at 4K. The percentage drop from 1080p to 4K at Ultra is 53.9%, which is remarkably consistent with the Low preset’s scaling. This consistency suggests that the RTX 4070 Ti’s rendering pipeline is the dominant constraint across all settings, with the Ryzen 7 7800X3D’s 96 MB of shared L3 cache providing ample headroom to feed the GPU without introducing CPU-bound limitations.

Interestingly, the gap between 1440p and 4K narrows as settings increase. At Low, the drop from 1440p to 4K is 38.8%, while at Ultra it is 37.9%. This indicates that the GPU’s memory subsystem and shading units are being utilized more efficiently at higher graphical loads, rather than hitting a hard bandwidth ceiling. The 504.2 GB/s of memory bandwidth and 12 GB of GDDR6X appear sufficient for the 4K Ultra workload, as the frame rate remains playable at 70.1 FPS.

How This Combo Ranks

Within the database of tested combinations for Downfall, this pairing holds the 216th position out of 1741 total combos, placing it in the top 12.4% of all tested systems. This ranking is particularly strong given that the CPU’s percentile versus all CPUs is 87, while the GPU’s percentile versus all GPUs is 85. The combo rank of 216 suggests that the synergy between these two components outperforms what their individual percentiles might predict, likely due to the 3D V-Cache technology in the 7800X3D benefiting the horror genre’s typical scene complexity.

The CPU’s nearest rival, the Intel Core i7-12700F, has an average benchmark score of 31543 versus the 7800X3D’s 31580, a delta of only 0.1%. This negligible difference in synthetic benchmarks does not translate to gaming performance, however, as the 7800X3D’s cache architecture provides superior frame pacing in real-world scenarios. The GPU’s closest competitor, the NVIDIA GeForce RTX 5090 Mobile, scores 45152 against the 4070 Ti’s 44900, a 0.6% deficit that puts the desktop card slightly behind a mobile flagship in raw compute but ahead in sustained gaming workloads.

Settings Recommendations

The measured FPS data strongly favors High settings at 2560x1440 as the optimal balance between visual fidelity and performance. At this configuration, the combo produces 174.2 FPS, which is more than sufficient for high-refresh-rate displays. The jump from High to Ultra at 1440p costs 35.1% of the frame rate, dropping to 113 FPS, which still clears the 100 FPS threshold for competitive play but sacrifices the fluidity that the 7800X3D’s strong single-thread performance (Cinebench R23 single-core score of 4115) enables.

For 4K gaming, High settings at 110.6 FPS provides the best experience, as Ultra drops to 70.1 FPS — a 36.6% reduction that may introduce noticeable stutter in a horror title where frame consistency is critical for immersion. The Low preset at 4K reaches 161.8 FPS, but the visual degradation is likely unacceptable for a genre that relies heavily on atmospheric lighting and shadow detail. At 1080p, Medium settings at 299.2 FPS offers the highest frame rate while still maintaining adequate visual quality, though High at 246.6 FPS is recommended for users with 144Hz displays who prioritize image clarity.

Measured FPS Breakdown

At 1920x1080, the combo demonstrates exceptional headroom across all settings. The Low preset achieves 366 FPS, Medium reaches 299.2 FPS, High produces 246.6 FPS, and Ultra delivers 151.9 FPS. The scaling factor from Low to Ultra is 41.5%, indicating that the GPU’s shading units (7680) and texture mapping units (240) are being progressively saturated as settings increase. The 1080p results suggest that the CPU is not the limiting factor at any setting, as even the Ultra preset’s 151.9 FPS is well below the 7800X3D’s maximum capable output.

At 2560x1440, the frame rates remain robust: Low at 264.4 FPS, Medium at 211.4 FPS, High at 174.2 FPS, and Ultra at 113 FPS. The transition from High to Ultra at this resolution costs 61.2 FPS, which is the largest single-setting drop in the entire dataset. This suggests that the Ultra preset enables computationally expensive effects that disproportionately impact the GPU’s 80 ROPs. The 1440p results show that Medium offers a 21.3% improvement over High, making it a viable option for users targeting 240Hz displays.

At 3840x2160, the limits of the RTX 4070 Ti become apparent. Low yields 161.8 FPS, Medium produces 130.6 FPS, High achieves 110.6 FPS, and Ultra falls to 70.1 FPS. The gap between Medium and High at 4K is only 15.3%, while the jump from High to Ultra is a substantial 36.6% reduction. This non-linear scaling indicates that the Ultra preset at 4K is likely activating effects that require more than the 12 GB of VRAM can efficiently handle, or that the 192-bit memory bus becomes a bottleneck for certain shader operations.

GPU Role

The RTX 4070 Ti’s memory configuration is central to its performance in Downfall. With 12 GB of GDDR6X across a 192-bit bus, the card achieves 504.2 GB/s of bandwidth. The data shows that at 4K Ultra, the frame rate drops to 70.1 FPS, which suggests the VRAM capacity may be near its limit, as the 4K High setting (110.6 FPS) demonstrates a 36.6% improvement despite increasing resolution demands. The 21 Gbps effective memory speed and 1313 MHz memory clock provide sufficient throughput for most scenarios, but the Ultra preset’s additional texture and shadow detail likely exceeds the comfortable working set.

The GPU’s clock behavior reveals its adaptive nature: a base clock of 2310 MHz and boost clock of 2610 MHz allow the card to scale performance based on thermal and power headroom. The 285 W TDP and 600 W suggested PSU indicate this is a power-hungry component, but the measured FPS suggests it maintains high boost clocks under sustained load. The 40.09 TFLOPS FP32 performance and 626.4 GTexel/s texture rate are well-matched to the 7800X3D’s 83.2 GB/s memory bandwidth, allowing the CPU to feed the GPU without creating a data starvation scenario.

The GPU’s ray tracing capabilities (60 RT cores) and tensor cores (240) are not directly measured in the FPS data, but the Ultra preset’s significant performance penalty suggests these features are being utilized. At 4K Ultra, the 70.1 FPS result indicates that the RT cores are handling the additional workload without causing a catastrophic drop, though the 36.6% reduction from High to Ultra is substantial. The 208.8 GPixel/s pixel rate and 80 ROPs appear to be the limiting factor for the Ultra preset, as the fill rate requirements at 4K with all effects enabled exceed what this configuration can deliver at high frame rates.
