Downfall

Downfall, a 2016 horror title, proves remarkably scalable on the Intel Core i5-12400 and NVIDIA GeForce RTX 5080 combination, delivering playable frame rates even at 4K Ultra. The data shows a system that is heavily GPU-bound at higher resolutions, with the CPU only becoming a potential factor at 1080p Low settings. The measured results indicate that the RTX 5080 is the dominant component in this pairing, with the i5-12400 providing sufficient throughput to avoid bottlenecking in most scenarios. This analysis breaks down the performance metrics to clarify where the limits lie and which settings offer the optimal experience.

Resolution Scaling

The performance drop from 1080p to 4K is significant and reveals a classic GPU-bound scenario. At High settings, the average frame rate falls from 278 FPS at 1920x1080 to 198 FPS at 2560x1440, and finally to 123 FPS at 3840x2160. This represents a 55.8% reduction in average FPS from 1080p to 4K, which is a substantial cost for the increased pixel count. The scaling is not linear, as the jump from 1440p to 4K (a 37.9% drop from 198 FPS to 123 FPS) is less severe than the jump from 1080p to 1440p (a 28.8% drop from 278 FPS to 198 FPS), suggesting that the GPU's memory bandwidth and raw compute are being taxed progressively harder as resolution increases.

At the lowest settings, the trend is even more pronounced, with the RTX 5080 pushing 387 FPS at 1080p but only 184 FPS at 4K, a 52.5% reduction. This large gap at Low settings indicates that while the GPU is still the primary limiter, the CPU's role becomes more apparent at lower resolutions. The i5-12400's six cores and 12 threads are likely reaching their limits in this older title when the GPU is not the bottleneck, capping performance at around 387 FPS. The data suggests that for players targeting high refresh rates at 1080p, the CPU may prevent the GPU from reaching its full potential, but this is a non-issue for standard 60Hz or even 144Hz displays given the sheer frame rates involved.

The 4K Ultra preset yields 77 FPS, which is the only scenario in the measured data where the system dips below the 100 FPS mark. The progression from Medium to High at 4K shows a 28 FPS difference (151 to 123), while the jump from High to Ultra costs another 46 FPS (123 to 77). This indicates that the Ultra preset includes effects that are disproportionately expensive at high resolutions, likely related to shadow quality and post-processing, making it a demanding choice for this GPU.

CPU Role

The Intel Core i5-12400, with its 6 cores and 12 threads, demonstrates that it is not the limiting factor in most of the measured scenarios for Downfall. The CPU's Cinebench R23 multi-core score of 15989 and single-core score of 2257 place it in the 72nd percentile of all CPUs, showing it as a capable mid-range processor. When paired with the RTX 5080, the data shows that frame rates scale almost entirely with resolution and settings, which is the expected behavior when the GPU is the bottleneck. The 1080p Low result of 387 FPS is the clearest indicator of CPU influence, as this is likely near the maximum frame rate the i5-12400 can generate in this game's engine.

The CPU's boost clock of 4.40 GHz and base clock of 2.50 GHz provide adequate single-thread performance for a 2016 title, which typically relies on a few heavily-threaded processes. The 3DMark single-thread score of 910 and the Passmark single-thread score of 3456 confirm that this processor has solid per-core performance. However, the game's age means it may not fully utilize the 12 threads, and the data implies that the CPU's ceiling is around the 387 FPS mark seen at 1080p Low. In all other tested configurations, the GPU's workload is high enough that the CPU is not the primary constraint, as evidenced by the smooth scaling from 1440p to 4K.

Compared to its nearest rivals, the i5-12400's average benchmark score of 18683 is within 0.9% of the Intel Core i3-14100F (18519) and 0.7% below the AMD Ryzen AI 5 330 (18811). This indicates that the CPU's performance is competitive with modern budget options, but its age is showing in the absolute frame ceiling. For Downfall, the CPU's role is to provide a stable foundation that rarely interferes with the GPU's output, and the measured FPS data confirms this, as the only potential CPU-bound scenario is the extreme low-resolution, low-settings combination.

GPU Role

The NVIDIA GeForce RTX 5080 is the undisputed performance driver in this system, as its benchmark scores and the measured FPS data make clear. With a Passmark G3D score of 36565 and a 3DMark Steel Nomad DX12 score of 8637, the GPU sits in the 87th percentile of all GPUs, outperforming its nearest rival, the AMD Radeon RX 9070 GRE, by 2.2% (57367 vs 56083 average score). The RTX 5080's 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is crucial for the high-resolution textures and effects in Downfall at 4K.

The GPU's boost clock of 2617 MHz and its 10752 shading units deliver the raw compute power needed to maintain high frame rates. The FP32 performance of 56.28 TFLOPS is substantial, and the data shows this power scales effectively across resolutions. At 4K Medium, the card produces 151 FPS, and at 4K High, it maintains 123 FPS, demonstrating that it can handle modern gaming loads in this older title without issue. The 4K Ultra result of 77 FPS, while lower, is still a playable frame rate, but it highlights the GPU's limits when all settings are maxed out.

The VRAM capacity of 16 GB is more than sufficient for Downfall, which was released in 2016 and does not have the massive texture requirements of modern titles. The measured data does not indicate any memory-related performance dips, as the frame rates remain consistent and scale predictably with resolution. The GPU's architecture, Blackwell 2.0, is built on a 5 nm process by TSMC, and its 45,600 million transistors are effectively utilized in this game. The RTX 5080 is clearly the component that determines the playable settings, as the CPU is only a minor factor in the most extreme low-load scenarios.

Settings Recommendations

Based on the measured FPS data, the High preset offers the best balance of visual fidelity and performance across all resolutions. At 1920x1080, High delivers 278 FPS, which is more than enough for any high-refresh-rate monitor. At 2560x1440, the High preset maintains 198 FPS, ensuring a smooth experience. Even at 3840x2160, High produces 123 FPS, which is excellent for a 4K display, providing a fluid experience without needing to compromise on quality. The Medium preset is a viable alternative for those seeking higher frame rates, with 339 FPS at 1080p and 151 FPS at 4K, but the visual downgrade is usually not worth the small FPS gain when High is already so performant.

The Ultra preset is the most demanding, and the data shows it should be avoided at higher resolutions. At 4K, Ultra drops to 77 FPS, which may be acceptable for a slower-paced horror game, but the 46 FPS loss compared to High is significant. At 1440p, Ultra yields 124 FPS, which is still playable, but the High preset's 198 FPS is a better target for competitive or fast-paced play. The Low preset is unnecessary for this hardware combination, as even at 4K it produces 184 FPS, but the visual quality will be severely compromised, making it a poor choice when the GPU can handle much higher settings.

The sweet spot for this system is the High preset at any resolution, as it provides the best combination of image quality and performance. For players with 4K displays, High is the recommended choice, as it keeps frame rates well above 100 FPS. For 1440p or 1080p users, High also excels, but Medium can be selected for those who prioritize maximum refresh rates, as it offers 242 FPS and 339 FPS respectively. The Ultra preset should only be used at 1080p (174 FPS) or 1440p (124 FPS) if visual fidelity is the absolute priority, but the performance cost is steep.
