Downfall

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 5060 delivers a highly capable 1080p experience in Downfall, but the data reveals a clear shift in bottleneck behavior as resolution increases. At 1080p, the combo produces exceptionally high frame rates across all settings, from 100 FPS at Ultra to 239.1 FPS at Low, indicating that the CPU is the primary limiting factor at this resolution. Moving to 1440p, the system still performs admirably, with the RTX 5060 taking on more load, while at 4K, the GPU becomes the definitive constraint, as evidenced by the frame rate scaling pattern. This analysis examines the measured FPS data to determine how this specific combination of a six-core Coffee Lake processor and a Blackwell 2.0 GPU behaves across different resolutions and quality presets in this horror title.

Resolution Scaling

The measured FPS data shows a predictable yet informative pattern across the three tested resolutions. At 1080p, the average frame rates are remarkably high, ranging from 100 FPS at Ultra settings to 239.1 FPS at Low. The jump from Medium to Low at this resolution is substantial—from 198.8 FPS to 239.1 FPS—which represents a 20.3% increase in performance. This significant gain at lower settings strongly suggests that the Intel Core i5-9400, with its 6 cores and 6 threads, is the limiting component at 1080p, as the GPU has ample headroom to render frames far faster than the CPU can feed it.

When scaling to 1440p, the frame rates remain very playable but show a more moderate decline. The High preset drops from 158.4 FPS at 1080p to 114.9 FPS at 1440p, a reduction of 27.5%. This indicates that the workload is shifting towards the GPU, but the system is still not fully GPU-bound, as the performance gap between Low and Ultra settings at 1440p (172.5 FPS vs 72.3 FPS) remains wide. The 4K results tell a different story. At 3840x2160, the High preset delivers 70.1 FPS, which is a 39% drop from the 1440p result. The Ultra preset at 4K falls to 47.5 FPS, making it the only setting below the 60 FPS threshold across all tested configurations. This steep decline at 4K, combined with the relatively smaller difference between Low (108 FPS) and Ultra (47.5 FPS) at this resolution, confirms that the NVIDIA GeForce RTX 5060 is now the primary bottleneck, as the GPU's 8 GB of GDDR7 memory and 128-bit bus width become stressed by the higher pixel count.

FAQ

Q: What is the best resolution for this combo in Downfall?

A: The 1440p resolution offers the best balance of visual quality and performance. The High preset at 2560x1440 delivers 114.9 FPS, which is well above the 60 FPS target, while the 4K High preset drops to 70.1 FPS, showing that the RTX 5060 starts to struggle at the highest resolution.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor based on the Coffee Lake architecture, operating at a base clock of 2.90 GHz and a boost clock of 4.10 GHz. This configuration, while dated, provides sufficient processing power for Downfall at most settings. The CPU's benchmark scores show a Cinebench R23 multi-core score of 7969 and a single-core score of 1125, placing it at the 50th percentile of all CPUs. This mid-range standing is reflected in its nearest rivals, including the Intel Core i3-10305 (0.2% faster) and the Intel Core i7-8809G (0.6% slower), indicating that the i5-9400 is performance-competitive with several other mainstream options.

In Downfall, the CPU's role is most apparent at 1080p, where the frame rates plateau at higher settings. The difference between High (158.4 FPS) and Medium (198.8 FPS) at 1080p is 40.4 FPS, but the jump to Low (239.1 FPS) is another 40.3 FPS. This linear scaling with reduced settings suggests that the CPU's 6 threads are the primary constraint, as the GPU could theoretically render even more frames if the CPU could provide them. The 9 MB of shared L3 cache and dual-channel DDR4 memory support at 42.7 GB/s are adequate for this workload, but the lack of hyper-threading limits the CPU's ability to handle multiple game threads simultaneously, which is a common requirement in modern horror titles like Downfall.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and frame rate preference. For 1080p gaming, the High preset at 158.4 FPS is the recommended choice, as it provides a substantial visual improvement over Medium (198.8 FPS) while still maintaining a frame rate well above the 144 Hz refresh rate that many monitors support. The Ultra preset at 100 FPS is also viable for those prioritizing visual fidelity, but the 36.9% performance penalty compared to High makes it a less efficient choice.

At 1440p, the High preset at 114.9 FPS is the best balance, as it offers smooth gameplay on high-refresh-rate monitors while the Medium preset at 137.8 FPS provides minimal visual gains for a 19.9% performance increase. The 4K resolution presents a trade-off: the Medium preset at 85.9 FPS is the highest setting that maintains a solid frame rate, while the High preset at 70.1 FPS is still playable but approaches the lower boundary of smooth performance. The Ultra preset at 47.5 FPS should be avoided at 4K, as it falls below the 60 FPS threshold and will result in noticeable stuttering. For the best overall experience, the data supports using the High preset at 1440p, which delivers 114.9 FPS without compromising visual quality.

How This Combo Ranks

The Intel Core i5-9400 + NVIDIA GeForce RTX 5060 combination ranks 855th out of 1741 tested combos in Downfall, placing it just below the median of all tested systems. This ranking reflects the CPU's mid-range status, as the RTX 5060 itself performs at the 73rd percentile of all GPUs, with an average benchmark score of 30109. The GPU's nearest rivals include the AMD Radeon RX 7700 XT (0% difference) and the NVIDIA GeForce RTX 5070 Mobile (0.6% faster), showing that the RTX 5060 is a competitive mid-range graphics card.

The combo's rank in this game is likely held back by the i5-9400's 50th percentile CPU performance, as evidenced by the 1080p results where the CPU becomes the bottleneck. In contrast, the GPU's strong benchmark scores, such as the Geekbench OpenCL score of 120785 and Passmark G3D score of 20891, indicate that it is capable of much higher frame rates than the CPU can deliver at lower resolutions. This mismatch between CPU and GPU capability is a common theme in older processors paired with newer graphics cards, and the data confirms that the i5-9400 is the limiting factor in this configuration, particularly at 1080p.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across all settings and resolutions. At 1920x1080, the average frame rates are 239.1 FPS (Low), 198.8 FPS (Medium), 158.4 FPS (High), and 100 FPS (Ultra). These results show a clear progression, with the Low preset delivering 2.4x the frame rate of the Ultra preset. At 2560x1440, the averages are 172.5 FPS (Low), 137.8 FPS (Medium), 114.9 FPS (High), and 72.3 FPS (Ultra). The 1440p results show a similar pattern, with a 2.4x difference between Low and Ultra, but the absolute values are lower due to the increased pixel count.

At 3840x2160, the averages drop to 108 FPS (Low), 85.9 FPS (Medium), 70.1 FPS (High), and 47.5 FPS (Ultra). The 4K results show a less dramatic spread between Low and Ultra (2.3x), but the key observation is that the High preset at 4K (70.1 FPS) is only 44.3% of the 1080p High result (158.4 FPS). This indicates that the RTX 5060's 8 GB of GDDR7 memory and 448.0 GB/s bandwidth are sufficient for 1080p and 1440p, but the higher memory pressure at 4K causes a more significant performance hit, especially at higher settings.

GPU Role

The NVIDIA GeForce RTX 5060 is a Blackwell 2.0 architecture GPU built on a 5 nm process at TSMC, featuring 3840 shading units, 120 texture mapping units, and 48 ROPs. The GPU operates at a base clock of 2280 MHz and a boost clock of 2497 MHz, with 8 GB of GDDR7 memory on a 128-bit bus providing 448.0 GB/s of bandwidth. These specifications contribute to a Passmark G3D score of 20891, which places the GPU at the 73rd percentile of all graphics cards. The RTX 5060's nearest rivals include the AMD Radeon RX 7700 XT (0% difference) and the NVIDIA Tesla M60 (0.5% slower), confirming its position as a solid mid-range performer.

In Downfall, the GPU's role becomes increasingly important as resolution increases. At 1080p, the GPU is largely underutilized due to the CPU bottleneck, but at 1440p, the GPU begins to show its capabilities, with the High preset delivering 114.9 FPS. At 4K, the GPU is the clear limiting factor, as the Ultra preset drops to 47.5 FPS, which is below the playable threshold. The GPU's 30 RT cores and 120 tensor cores provide hardware support for ray tracing and DLSS, but the measured FPS data does not include these features, so the baseline performance is what is analyzed here. The GPU's 145 W TDP and dual-slot design make it a power-efficient choice for this pairing, and its PCIe 5.0 x8 interface ensures sufficient bandwidth for the CPU's PCIe Gen 3, 16 Lanes connection, though the older CPU interface may slightly limit data transfer speeds in some scenarios.
