Downfall

The Intel Core i5-12400 and NVIDIA GeForce RTX 3080 combination delivers a robust performance profile in Downfall, a horror title that scales predictably with resolution and quality settings. Measured data shows the pair is capable of high refresh rate play at 1080p and 1440p, with 4K remaining viable at most settings. The following analysis breaks down the measured FPS, component roles, and alternative hardware.

Measured FPS Breakdown

At 1920x1080, the combo produces exceptional frame rates across all presets. With Low settings, the average FPS reaches 297.1, making it a clear candidate for maximum refresh rate displays. Moving to Medium drops the average to 244.6, while High settings still deliver a strong 200.3 average. Even the most demanding Ultra preset holds an average of 124.9, which is well above the 60 FPS playable threshold. The scaling from Low to Ultra shows a performance reduction of roughly 58%, but every preset at this resolution clears the playability bar with significant headroom.

At 2560x1440, the pattern continues but with tighter margins. Low settings produce an average of 216.5 FPS, and Medium follows at 173.7. The High preset averages 144 FPS, which is exactly double the playable threshold, indicating a smooth experience for high-refresh monitors. Ultra at this resolution averages 91.1 FPS, a notable drop from the 1080p Ultra figure of 124.9, but still comfortably playable. The gap between Low and Ultra at 1440p is about 58%, similar to the 1080p scaling, suggesting the game's settings have a consistent performance cost across these resolutions.

At 3840x2160, the RTX 3080 begins to show its limits. Low settings average 131.3 FPS, which is still very fast. Medium drops to 109.6, and High averages 91.1 FPS — matching the 1440p Ultra result. The story changes at Ultra, where the average plummets to 55.4 FPS, falling below the 60 FPS playable threshold. This is the only measured configuration that fails to maintain playability. From Low to Ultra at 4K, the performance drop is approximately 58%, consistent with other resolutions, but the starting point is lower, pushing Ultra out of the playable range.

Notably, the measured data includes no min or max FPS values, so the analysis relies solely on average frame rates. The absence of frame time variance data means stutter or drop severity cannot be assessed, but the averages suggest a stable experience at the playable presets.

CPU and GPU Roles

The data shows a clear division of labor between the Intel Core i5-12400 and the NVIDIA GeForce RTX 3080, with the GPU becoming increasingly dominant as resolution rises. At 1920x1080, the CPU's role is more prominent relative to higher resolutions, as evidenced by the high frame rates that approach the processor's limits. The i5-12400, with its 6 cores and 12 threads, provides enough single-thread performance — a 3dmark_single_thread score of 910 and a passmark_single_thread score of 3456 — to feed the GPU at lower resolutions. The drop from Low to Ultra at 1080p (from 297.1 to 124.9 FPS) is substantial, but the absolute numbers indicate that the GPU is still the primary bottleneck at Ultra, as the CPU can likely handle more frames than the GPU can render.

At 2560x1440, the scaling between presets narrows slightly, and the GPU's load increases. The average FPS at Ultra (91.1) is significantly lower than at 1080p Ultra (124.9), a 27% reduction. This suggests the GPU is now the limiting factor, as the CPU's workload does not increase with resolution, but the GPU's pixel output does. The CPU's multi-threaded capabilities, such as a cinebench_r23_multicore score of 15989 and a passmark_multithread score of 18747, are sufficient to avoid bottlenecking at this resolution.

At 3840x2160, the GPU is unequivocally the dominant component. The difference between 1440p and 4K at Ultra is stark: 91.1 FPS versus 55.4 FPS, a 39% drop. This is almost entirely attributable to the GPU's rendering load, as the CPU's contribution to frame generation at 4K is typically minimal. The RTX 3080's 10 GB of GDDR6X memory and 760.3 GB/s bandwidth are taxed heavily at this resolution, especially at Ultra settings. The CPU's role diminishes to that of a stable frame provider, and the i5-12400's performance metrics — including a passmark_physics score of 1105 and a 3dmark_max_threads score of 5890 — indicate it is more than capable of keeping up. The verdict is clear: at 1080p and 1440p, the CPU matters more, but at 4K, the GPU dictates the experience.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU and GPU provides context for what other hardware would deliver comparable results in Downfall. The Intel Core i5-12400 has an average benchmark score of 18683, placing it at the 72nd percentile among all CPUs. Its nearest rivals include the AMD EPYC 7643 with an average score of 18697 (a -0.1% delta), the Intel Core i7-1355U at 18730 (-0.3%), and the AMD Ryzen AI 5 330 at 18811 (-0.7%). The Intel Core i3-14100F is also close, scoring 18519 with a +0.9% delta, meaning it performs slightly below the i5-12400. For Downfall, any of these CPUs would produce similar frame rates, especially at higher resolutions where the GPU is the bottleneck. The differences in synthetic scores are minimal, and the game's reliance on single-thread performance (as seen in the 1080p results) is well-served by all these chips.

For the GPU, the NVIDIA GeForce RTX 3080 has an average benchmark score of 23172, ranking at the 68th percentile among all GPUs. Its nearest rivals are surprising in their diversity: the NVIDIA P106-100 (score 23249, delta -0.3%), the AMD Radeon Pro Vega 16 (score 23250, delta -0.3%), the AMD Radeon RX 6600M (score 23273, delta -0.4%), and the AMD Radeon R9 M290X (score 23276, delta -0.4%). These delta values are all within a fraction of a percent, indicating that despite their different architectures and market positions, their aggregate benchmark scores are nearly identical to the RTX 3080. In Downfall, a system with one of these GPUs would likely produce very similar FPS numbers, though the RTX 3080's specific feature set (like its 68 RT cores and 272 tensor cores) may not be fully utilized by this horror game, which is not a ray tracing showcase. The practical takeaway is that the RTX 3080's performance at 1080p and 1440p is representative of a broad performance tier, and the measured FPS would be closely mirrored by these alternatives.

The Verdict

The Intel Core i5-12400 and NVIDIA GeForce RTX 3080 can absolutely run Downfall, and the data shows it does so with high frame rates at most settings. At 1920x1080, every preset — Low, Medium, High, and Ultra — clears the 60 FPS playable threshold, with Ultra averaging 124.9 FPS. The best settings at this resolution are Ultra, providing the highest visual quality while still more than doubling the playability bar. At 2560x1440, all four presets are also playable, including Ultra at 91.1 FPS, which is the recommended best setting for a balance of quality and speed. At 3840x2160, the situation is more nuanced. High settings are the best playable option, averaging 91.1 FPS, and Low (131.3 FPS) and Medium (109.6 FPS) also pass the threshold. However, Ultra at 4K fails, averaging 55.4 FPS, which is below the 60 FPS mark. For a 4K experience, the data recommends sticking to High settings to maintain smooth gameplay. Overall, the system provides a playable experience at 1080p and 1440p with maxed-out settings, and at 4K with a modest reduction to High.

How This Combo Ranks

In the benchmark database for Downfall, this specific combination of the Intel Core i5-12400 and NVIDIA GeForce RTX 3080 ranks 1053 out of 3716 tested combos. This places it in the upper third of all tested systems, roughly the 72nd percentile position for CPUs and 68th percentile for GPUs. The rank reflects the system's ability to handle the game's demands, particularly given that it achieves playable frame rates at all resolutions except 4K Ultra. The ranking is consistent with the measured FPS data: the system is not at the very top tier, which would likely include more powerful GPUs or newer CPUs, but it sits comfortably above the median. The high FPS numbers at 1080p and 1440p suggest that the rank could be higher if the game were more CPU-bound, but the GPU's performance at 4K pulls the overall standing down slightly. For a horror game like Downfall, which does not appear to be exceptionally demanding, this combo ranks well and offers a smooth experience across most settings, with the only caveat being the 4K Ultra preset.
