Downfall

Resolution Scaling

The measured FPS data for Downfall shows a predictable but steep performance curve as resolution climbs from 1920x1080 to 3840x2160. At 1080p with High settings, the combo posts 144.3 FPS, which drops to 103 FPS at 1440p and further to 65.1 FPS at 4K. That represents a 55% reduction in frame rate from 1080p to 4K, a substantial scaling penalty that points squarely at the GPU as the primary bottleneck at higher resolutions.

The pattern becomes more telling when examining Low settings across resolutions. At 1080p Low, the system reaches 213.9 FPS, while 1440p Low yields 151.6 FPS and 4K Low drops to 98 FPS. The 4K-to-1080p ratio here is 0.46, meaning 4K delivers less than half the frame rate of 1080p. This is characteristic of a GPU-bound scenario where pixel throughput, not CPU capability, defines the ceiling.

Ultra settings tell an even starker story. The 1080p Ultra result of 93 FPS falls to 65.7 FPS at 1440p and collapses to 38.8 FPS at 4K Ultra. The 4K Ultra figure is less than half of the 1080p Ultra number, and the absolute value of 38.8 FPS approaches the threshold where horror-game responsiveness becomes marginal. The data indicates that this combination is not viable for 4K Ultra play in Downfall, as the frame rate drops below what most users would consider smooth.

The scaling behavior across settings tiers reveals where the limiting component shifts. At 1080p, the gap between Low (213.9 FPS) and Ultra (93 FPS) is 120.9 FPS, showing that settings have a massive impact at lower resolution. At 4K, the same Low-to-Ultra spread is only 59.2 FPS (98 vs 38.8). This compression of the settings delta at higher resolution indicates the GPU is saturated at 4K regardless of quality preset, whereas at 1080p there is headroom that settings can exploit.

GPU Role

The NVIDIA GeForce GTX 1080 Ti sits at the center of this combo’s performance profile. Its 11 GB of GDDR5X memory on a 352-bit bus delivers 484.4 GB/s of bandwidth, which is substantial for a card of its generation. The base clock of 1481 MHz and boost clock of 1582 MHz are modest by modern standards, but the 3584 shading units and 88 ROPs provide raw throughput that the benchmark results reflect.

In Downfall, the GPU’s role becomes increasingly dominant as resolution rises. The measured FPS scaling from 1080p to 4K at High settings (144.3 to 65.1 FPS) suggests that the 1080 Ti is the binding constraint at 4K. The card’s 11.34 TFLOPS of FP32 compute and 139.2 GPixel/s pixel rate are being pushed hard by the 3840x2160 pixel count. At 4K Ultra, the 38.8 FPS result indicates the GPU is fully saturated, with the pixel shader workload overwhelming the card’s capabilities.

The GTX 1080 Ti’s percentile ranking of 61 among all GPUs places it in the upper-middle tier, and its nearest rival data shows it trading blows with the NVIDIA TITAN Xp, which scores 1.1% higher on average. The GTX 780 sits at parity with a deltaPct of 0, while the AMD Radeon Pro 560X trails by 0.1%. This positioning explains why the card can handle 1440p High at 103 FPS but struggles to maintain playability at 4K Ultra.

Memory bandwidth appears adequate for this game’s needs. The 484.4 GB/s figure is high enough that VRAM bandwidth is unlikely to be the limiting factor at 1080p or 1440p, where the card delivers 144.3 and 103 FPS respectively at High settings. Only at 4K Ultra does the combination of memory pressure and compute load push the card to its limits, yielding the 38.8 FPS result.

CPU Role

The Intel Core i5-12400 provides the processing foundation for this combo, and its performance characteristics are well-suited to Downfall’s demands. With 6 cores and 12 threads, the CPU offers a boost clock of 4.40 GHz and a base clock of 2.50 GHz. The Alder Lake architecture with 18 MB of shared L3 cache delivers single-thread performance that is critical for game logic and frame pacing.

The CPU’s benchmark scores indicate strong multi-threaded capability. The Cinebench R23 multi-core result of 15935 and single-core result of 2249 show a balanced profile. The 3DMark results further reinforce this: 910 in single-thread, 1692 in 2-thread, and 5873 in 16-thread tests. These numbers suggest the i5-12400 can feed the GTX 1080 Ti adequately at lower resolutions where the GPU is not the bottleneck.

At 1080p Low, the system achieves 213.9 FPS, which is high enough that CPU overhead could conceivably become a factor. However, the fact that the frame rate scales smoothly from Low to Ultra at 1080p (213.9 to 93 FPS) indicates the CPU is not limiting performance at this resolution. The CPU’s percentile ranking of 77 among all CPUs, with an average benchmark score of 19850, places it above the GPU’s relative standing, supporting the interpretation that the GPU is the primary constraint.

The nearest rival data for the CPU shows tight competition: the Intel Core i7-9700 is 0.1% faster, the Intel Core i7-8700 is 0.2% slower, and the AMD Ryzen Threadripper PRO 5995WX trails by 0.4%. This clustering suggests the i5-12400 is firmly in the mid-range performance tier, providing sufficient compute headroom for Downfall without becoming the limiting factor in most scenarios.

This mid-tier ranking aligns with the individual component percentiles: the CPU at 77th and the GPU at 61st. The combo’s ranking is dragged down by the GPU’s relative position, as the CPU is capable of supporting a more powerful graphics card.

Interpreting this ranking requires context. With 1741 combos tested, a rank of 1003 means there are 738 systems that perform worse and 1002 that perform better. The system sits squarely in the middle of the distribution, which is consistent with the measured FPS data. At 1080p High, the 144.3 FPS result is strong, but many combos with newer or higher-tier GPUs will exceed this figure.

The ranking suggests this combo is best suited for 1080p and 1440p gaming in Downfall, where it delivers competitive frame rates. At 4K, the system falls behind more powerful GPU pairings, particularly at Ultra settings where the 38.8 FPS result would rank poorly against systems with flagship cards. The measured data confirms that this is a balanced mid-range combination that excels at mainstream resolutions but struggles at the high end.

The delta between the CPU and GPU percentiles (77 vs 61) indicates an imbalance in this pairing. The i5-12400 has more headroom than the GTX 1080 Ti can utilize, meaning the GPU is the constraining factor in most scenarios. Upgrading the GPU would likely yield better returns than upgrading the CPU for Downfall performance, as the CPU’s 77th percentile ranking provides ample compute capacity for this game’s demands.
