Downfall

The AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 3080 Ti combination delivers a remarkably consistent experience in Downfall, a 2016 horror title that scales predictably across resolution and quality presets. The measured frame rates show a system that is rarely stressed at 1080p, becomes more balanced at 1440p, and finally hits its limits at 4K Ultra, where the GPU’s 12 GB memory and 384-bit bus become the defining factors. This analysis breaks down the data into actionable insights for builders and upgraders.

Resolution Scaling

The measured FPS data for this combo in Downfall reveals a classic GPU-bound scaling curve, but with an unusual twist at the highest settings. At 1080p Low, the system produces 311 FPS average, which drops to 254 FPS at Medium, then 208 FPS at High, and finally 130 FPS at Ultra. That is a drop of 181 FPS (58%) from Low to Ultra at 1080p, indicating that even at this resolution, the graphics card is doing most of the heavy lifting. The delta between Low and Ultra at 1080p is steep, but the absolute numbers remain high enough that no user would complain about playability.

Moving to 1440p, the same preset ladder shows 222 FPS at Low, 182 FPS at Medium, 149 FPS at High, and 93 FPS at Ultra. The relative drop from Low to Ultra at 1440p is 129 FPS (58%), nearly identical in percentage terms to the 1080p drop. This consistency suggests the game engine scales uniformly with pixel count, and the RTX 3080 Ti’s raw throughput is the primary limiter. The 1440p High result of 149 FPS is particularly notable because it sits above the 4K Low result of 138 FPS, highlighting how resolution, not just quality, dominates performance.

At 4K, the curve steepens dramatically. Low settings yield 138 FPS, Medium drops to 113 FPS (with a minimum of 96 FPS and maximum of 130 FPS recorded), High falls to 93 FPS, and Ultra collapses to 58 FPS. The jump from High to Ultra at 4K is a 35 FPS loss (38%), which is the largest single-tier penalty across all resolutions. This indicates that Ultra at 4K introduces a rendering workload that the RTX 3080 Ti cannot sustain, likely due to memory bandwidth saturation or pixel fill rate limits. The 4K Medium result of 113 FPS, with a minimum of 96 FPS, shows that the card can hold respectable frame times when not pushed to extremes.

The data suggests that the limiting component shifts with resolution. At 1080p, the CPU—a 12-core, 24-thread Zen 5 part with a 5.50 GHz boost clock—is more than capable of feeding frames, as evidenced by 311 FPS at Low. At 4K Ultra, the GPU is clearly the bottleneck, with the 58 FPS average representing a 81% reduction from the 1080p Low figure. The sweet spot for this combo appears to be 1440p High or 4K Medium, where the balance between resolution and quality keeps the GPU in its efficient range.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing, and its specifications explain the measured behavior. The card features 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth. In Downfall, a horror title that likely uses high-resolution textures and volumetric effects, this memory configuration is sufficient for 4K Medium but becomes strained at 4K Ultra, where the 58 FPS average suggests the GPU is running out of memory or bandwidth headroom.

The GPU’s clock behavior is also relevant. The base clock is 1365 MHz with a boost of 1665 MHz, and the memory runs at 1188 MHz (19 Gbps effective). These clocks are modest by modern standards, but the GA102 chip’s 10,240 shading units and 112 ROPs provide substantial raw compute. The pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s are the theoretical limits that the measured FPS data confirms. At 4K Ultra, the 58 FPS average implies the pixel fill rate is being challenged, especially with the game’s horror atmosphere likely relying on heavy post-processing effects.

The RTX 3080 Ti’s benchmark scores place it in the 83rd percentile among all GPUs, with an average benchmark score of 41187. Its nearest rivals include the AMD Radeon Pro 5300 (0.8% higher score), NVIDIA Tesla M40 24 GB (1.2% lower), and NVIDIA GeForce RTX 5070 (2% lower). These deltas are small, suggesting the 3080 Ti remains competitive in synthetic tests, but the Downfall data shows real-world performance is more nuanced. The 12 GB VRAM is a potential limitation for future titles, but in this 2016 game, it is only at 4K Ultra that the card shows clear signs of stress.

The measured FPS at 1080p Low (311 FPS) and Medium (254 FPS) indicates the GPU is not the bottleneck at lower resolutions, as the CPU can maintain high frame rates. However, the RTX 3080 Ti’s 350 W TDP and 12-pin power connector suggest it is a power-hungry component, and the 750 W suggested PSU is a consideration for system builders. The card’s 285 mm length and dual-slot design are typical for this class, but the data does not indicate any thermal throttling issues in the measured results.

Settings Recommendations

Based on the measured FPS rows, the best experience for this combo in Downfall depends on the target display. For 1080p users, High settings at 208 FPS average provide an excellent balance, as the jump to Ultra (130 FPS) costs 78 FPS for marginal visual gains. The 1080p Medium preset at 254 FPS is also viable for competitive play, but High is recommended for the best visual fidelity without sacrificing smoothness. The 1080p Low setting at 311 FPS is excessive for most displays, as it exceeds the refresh rate of all but the most extreme monitors.

At 1440p, High settings at 149 FPS average are the clear recommendation. This result is 56 FPS higher than Ultra (93 FPS) and only 33 FPS lower than Medium (182 FPS), providing a strong balance. The 1440p Medium preset at 182 FPS is also excellent, but High’s visual improvements are worth the modest frame rate reduction. The 1440p Ultra setting at 93 FPS is playable but below the 100 FPS threshold that many users prefer, and the 4K data suggests that Ultra at higher resolutions is not the intended use case for this card.

For 4K, Medium settings at 113 FPS average, with a minimum of 96 FPS and maximum of 130 FPS, are the only sensible choice. The 4K High result of 93 FPS is borderline, but the 4K Ultra result of 58 FPS is too low for a smooth horror experience, where consistent frame times matter for atmosphere. The 4K Low setting at 138 FPS is technically playable but defeats the purpose of 4K resolution, as visual quality suffers. The measured minimum of 96 FPS at 4K Medium indicates that even in demanding scenes, the combo can hold above 60 FPS, making this the only 4K preset that offers both fidelity and performance.

How This Combo Ranks

The combo ranks 709th out of 2928 tested combinations in Downfall, which places it in the upper quartile of all systems. This ranking is notable because it reflects the RTX 3080 Ti’s age (released in 2021) and the CPU’s relative newness (released in 2025). The GPU’s 83rd percentile ranking among all GPUs and the CPU’s 91st percentile ranking among all CPUs suggest that the combo is well-matched, with neither component dramatically outperforming the other in synthetic benchmarks.

The measured FPS data supports this ranking. At 1080p, the combo produces frame rates (208-311 FPS) that would be competitive with much newer hardware, but at 4K Ultra (58 FPS), it falls behind systems with more powerful GPUs. The rank of 709 out of 2928 means that 2219 other combinations perform better, which is expected given the GPU’s end-of-life status. However, the fact that it ranks in the top 24% despite the GPU being from 2021 indicates that the CPU’s 12-core, 24-thread configuration with 128 MB of L3 cache helps maintain high minimum frame rates, particularly in horror games that may have CPU-bound moments.

The nearest rival data for the CPU shows it is within 2.1% of the Intel Core i7-14700F and Intel Xeon 6505P, while the GPU is within 2% of the NVIDIA GeForce RTX 5070. These small deltas mean that swapping either component for a close rival would not dramatically change the Downfall experience, but the combination’s overall rank is a product of both parts working together. The 4K Medium result of 113 FPS is a strong indicator of the combo’s capability, as it demonstrates that the system can handle high-resolution gaming when settings are adjusted appropriately.

CPU Role

The AMD Ryzen 9 9900X3D plays a supporting role in Downfall, but its specifications ensure that it never becomes the limiting factor. The CPU features 12 cores and 24 threads, with a base clock of 4.40 GHz and a boost clock of 5.50 GHz. This Zen 5 architecture, built on a 4 nm process, provides substantial single-thread and multi-thread performance, as evidenced by its Cinebench R23 scores of 6739 single-core and 47737 multi-core. The 128 MB of L3 cache is a key feature for gaming, as it reduces memory latency and improves frame pacing in CPU-bound scenarios.

In Downfall, the CPU’s role is most apparent at 1080p Low, where the system achieves 311 FPS. This frame rate is far above the refresh rate of typical monitors, and the data suggests that the CPU can handle even higher frame rates if the GPU were faster. The 3DMark single-thread score of 1269 and multi-thread score of 13795 indicate strong per-core performance, which is critical for a 2016 game that may not be heavily multi-threaded. The Geekbench single-core score of 3041 and multi-core score of 22884 further confirm that the CPU has ample headroom for this title.

The CPU’s 120 W TDP and dual-channel DDR5 memory support (89.6 GB/s bandwidth) are sufficient for the game’s demands. The 24 PCIe Gen 5 lanes provide ample bandwidth for the RTX 3080 Ti, which uses PCIe 4.0 x16. The CPU’s benchmark percentile of 91st among all CPUs means it outperforms the vast majority of processors, and its nearest rivals—the Intel Core Ultra 5 245KF (0.6% lower score), Intel Core Ultra 5 245K (1.3% higher), and Intel Xeon 6505P (2% higher)—are all close in synthetic performance. However, in Downfall, the CPU’s 3D V-Cache (implied by the X3D branding) likely provides a tangible benefit in maintaining high minimum FPS, as horror games often load large texture sets and AI routines that benefit from large caches.

The data shows that the CPU is not the bottleneck at any tested resolution or setting, as the FPS scaling from 1080p to 4K follows the GPU’s expected behavior. At 4K Ultra, the CPU is likely waiting on the GPU, which explains the 58 FPS average. This balanced pairing means that users upgrading either component would see diminishing returns in Downfall, as the CPU can easily sustain the GPU’s maximum output. The CPU’s 5.50 GHz boost clock ensures that even single-threaded game logic runs at high speed, while the 24 threads provide headroom for background tasks. Overall, the Ryzen 9 9900X3D is an overqualified partner for the RTX 3080 Ti in this title, but it future-proofs the system for more demanding games.
