Downfall

Downfall, the 2016 horror title, responds dramatically to resolution and settings changes on this Intel Core i5-13400F and AMD Radeon RX 6800 XT pairing. The measured data reveals a system that is overwhelmingly GPU-bound at higher resolutions, but which shows surprising headroom at 1080p where the CPU begins to flex its muscles. The frame rates scale almost linearly with pixel count, indicating that the Radeon RX 6800 XT is the primary driver of performance in most scenarios, yet the i5-13400F proves it is no bottleneck even in the most demanding situations.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a steep and consistent performance curve across all settings presets. At the "Ultra" preset, average frame rates drop from 120.2 FPS at 1080p to 86.5 FPS at 1440p, and finally to 56.6 FPS at 4K. This represents a 53% reduction in frame rate from the lowest to the highest resolution, a clear indication that the rendering load is scaling directly with the pixel count and that the GPU is the limiting factor. The "High" preset tells a similar story, with 194 FPS at 1080p falling to 141 FPS at 1440p and then to 87.4 FPS at 4K, a 55% drop overall.

The "Medium" preset shows the same pattern, starting at 238.1 FPS at 1080p, dropping to 170.5 FPS at 1440p, and settling at 106.3 FPS at 4K. Even the "Low" preset, which is typically the most CPU-sensitive, exhibits a significant resolution penalty: 292 FPS at 1080p falls to 206 FPS at 1440p and then to 129.5 FPS at 4K. The fact that even at "Low" settings the 4K frame rate is less than half of the 1080p figure strongly suggests that the graphics card's fill rate and memory bandwidth are the dominant constraints. The gap between 1080p and 1440p is consistently larger than the gap between 1440p and 4K, which is expected given the non-linear increase in pixel count, but the overall trend confirms that this combination is tuned for high-refresh-rate 1440p gaming rather than maxing out 4K panels.

GPU Role

The AMD Radeon RX 6800 XT, with its 16 GB of GDDR6 memory on a 256-bit bus providing 512.0 GB/s of bandwidth, is the clear workhorse in this pairing. The data shows that the GPU's 72 ray accelerators and 4608 shading units are being fully utilized when the resolution increases. The 4K "Ultra" result of 56.6 FPS, while playable, demonstrates the hard ceiling of this card in this specific horror title when all visual features are enabled. The card's boost clock of 2250 MHz and base clock of 1825 MHz are typical for the RDNA 2.0 architecture, and the benchmark results indicate that the card maintains consistent performance without thermal throttling, as evidenced by the smooth scaling between settings.

The GPU's 16 GB frame buffer is a substantial asset in Downfall, as the difference between "High" and "Ultra" at 1440p (141 FPS vs 86.5 FPS) and 4K (87.4 FPS vs 56.6 FPS) suggests that the "Ultra" preset is pushing texture detail and post-processing effects that require significant memory capacity and bandwidth. The card's position in the overall GPU hierarchy, ranking in the 87th percentile versus all GPUs, is reflected in these results; it is a high-end part that delivers excellent 1440p performance but is not quite sufficient for a locked 60 FPS at 4K with everything maxed out. The data indicates that the GPU is the primary bottleneck at 1440p and 4K, but at 1080p, the frame rates are so high (194 FPS on "High") that the CPU begins to play a more significant role in determining the final output.

CPU Role

The Intel Core i5-13400F, with 10 cores and 16 threads running at a base clock of 2.50 GHz and a boost clock of 4.60 GHz, is a capable partner that rarely holds back the GPU. The measured data shows this most clearly at 1080p with the "Low" preset, where the system achieves 292 FPS. This high frame rate is only possible if the CPU can feed the GPU with draw calls quickly enough, and the i5-13400F's performance in the 82nd percentile versus all CPUs confirms it has the single-threaded and multi-threaded muscle for the job. The processor's 20 MB of shared L3 cache and 1.25 MB per-core L2 cache help maintain low latency in the game's logic and physics, which are often single-threaded in older horror titles like this one.

The CPU's impact is more visible when comparing the "Low" and "Medium" presets at 1080p. The jump from 292 FPS to 238.1 FPS shows that the GPU is still the primary constraint, but the fact that the "Low" preset is only 23% faster than "Medium" at 1080p, while at 4K the difference is 129.5 FPS vs 106.3 FPS (a 22% gap), suggests the CPU is not adding a disproportionate overhead at lower resolutions. The i5-13400F's Cinebench R23 multi-core score of 21279 points and single-core score of 3004 points are indicative of a processor that can easily handle the game's threading model. In this context, the CPU is never the sole bottleneck; it provides enough headroom to allow the GPU to scale its performance up to the 292 FPS peak observed at 1080p Low.

How This Combo Ranks

Within the database of 1741 tested combinations for Downfall, this particular pairing of the Intel Core i5-13400F and AMD Radeon RX 6800 XT achieves a rank of 580. This places it in the top third of all tested systems, which is a strong result given the age of the game and the combination of a mid-high range CPU with a high-end GPU. The ranking reflects the overall balance of the system; it is not an absolute top-tier setup, but it outperforms a majority of other pairings. The GPU's individual ranking (87th percentile) is higher than the CPU's (82nd percentile), which suggests that the graphics card is the component that is pulling the system up to this rank.

Comparing the CPU to its nearest rivals, the i5-13400F's average benchmark score of 25236 is nearly identical to the Intel Core i7-13620H, which scores 25201 (a delta of 0.1%), and it sits just 0.5% behind the AMD Ryzen 5 5600X3D's score of 25365. This indicates that the CPU is performing exactly as expected for its class. For the GPU, the RX 6800 XT's average score of 49982 is 0.5% ahead of the Intel Arc A550M's 49737, but it trails the NVIDIA RTX A1000 by 1.7%. The combination's 580th place ranking out of 1741 confirms the fact that while neither component is the absolute fastest in its respective category, they work exceptionally well together in this specific title, delivering a smooth and responsive experience that many other, nominally higher-ranked systems might not achieve due to driver or architectural inefficiencies.

Settings Recommendations

For players aiming for the best balance of visual fidelity and smooth frame rates, the "High" preset at 2560x1440 is the clear sweet spot, delivering an average of 141 FPS. This is well above the threshold for high-refresh-rate monitors, and the visual quality is only marginally below the "Ultra" preset, which drops to 86.5 FPS at the same resolution. The "Ultra" preset at 1440p is still playable, but the 54.5 FPS drop from "High" is a steep price for the extra visual effects. At 1080p, the "High" preset offers an exceptional 194 FPS, making it ideal for competitive or high-refresh-rate play, while the "Ultra" preset at 120.2 FPS is also very smooth and provides the best image quality for players who prioritize visuals over raw speed.

At 4K, the data suggests that the "High" preset (87.4 FPS) is the most sensible choice, as it maintains a frame rate that is above 60 FPS, whereas the "Ultra" preset (56.6 FPS) dips below that threshold. The "Medium" preset at 4K (106.3 FPS) is another viable option for players who want a higher frame rate headroom, but the visual compromise is noticeable compared to "High." The "Low" preset is generally not recommended for this combination, as even at 4K it only yields 129.5 FPS, which is not a significant improvement over "High" and comes with a substantial loss in visual quality. The optimal configuration is to leave the resolution at 1440p and select the "High" preset, which offers a perfect compromise of performance and fidelity, ensuring the game remains fluid and immersive without overtaxing the components.
