Downfall

The Intel Core i5-9400 is a six-core, six-thread Coffee Lake desktop processor with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. Its architecture is built on a 14 nm process, and it carries 9 MB of shared L3 cache. In synthetic workloads, the chip posts an average benchmark score of 2305, placing it in the 50th percentile of all CPUs tested. This places it in a dead heat with its nearest rivals: it sits just 0.2% ahead of the Intel Core i3-10305 and Intel Core i3-1125G4, and 0.4% ahead of the Intel Xeon E-2134. It trails the Intel Core i7-8809G by 0.6%. For a horror title like Downfall, which is not typically considered a heavily threaded workload, this processor’s six physical cores provide sufficient headroom for game logic and physics, though the lack of Hyper-Threading means it relies on raw clock speed to maintain frame pacing. The 4.10 GHz boost clock is the key asset here, as it ensures that single-threaded tasks—often dominant in horror game scripting—are handled without bottlenecking the GPU at lower resolutions.

GPU Role

The NVIDIA GeForce GTX 1650 is a Turing-architecture part built on TSMC’s 12 nm process, featuring 896 shading units, 56 texture mapping units, and 32 ROPs. Its base clock is 1485 MHz with a boost clock of 1665 MHz. The card is equipped with 4 GB of GDDR5 memory on a 128-bit bus, delivering 128.1 GB/s of bandwidth, and it draws a 75 W TDP. In terms of raw compute, it offers 2.984 TFLOPS of FP32 performance. The GTX 1650’s average benchmark score is 8713, which places it in the 43rd percentile of all GPUs. Its closest competitors are tightly clustered: it is 0.4% behind the NVIDIA GeForce RTX 3050 A Mobile and AMD Radeon 550X, 0.5% behind the NVIDIA Quadro P2200, and 0.5% ahead of the AMD Radeon Pro WX 5100. In Downfall, the GPU’s 4 GB VRAM capacity is the binding constraint at higher settings. The 128-bit memory interface limits fill-rate-bound scenarios, but the card’s boost clock of 1665 MHz helps maintain responsiveness. At 1080p Low, the GTX 1650 delivers 93.8 FPS, indicating that the GPU is the primary driver of performance. However, the 2.984 TFLOPS ceiling becomes evident as settings scale upward, with the card struggling to maintain playable frame rates at 4K Ultra.

Resolution Scaling

The measured FPS data reveals a clear relationship between resolution and the limiting component. At 1080p Low, the combo achieves 93.8 FPS, which suggests the CPU is capable of feeding the GPU adequately at lower resolutions. Dropping to 1440p Low, the average FPS falls to 65.1, a 30.6% reduction. At 4K Low, the average is 41.7 FPS, representing a 55.5% drop from the 1080p figure. This scaling pattern indicates that the GTX 1650 becomes increasingly the bottleneck as pixel count rises, because the CPU’s six cores can still keep up with the frame production at lower resolutions. Looking at High settings, the drop from 1080p to 1440p is 25.9% (61.3 to 45.4 FPS), and from 1080p to 4K it is 56.9% (61.3 to 26.4 FPS). The steepest proportional decline occurs between 1440p and 4K at Medium settings, where the average FPS falls from 54.2 to 35.8, a 34% reduction. These results show that the limiting component shifts decisively to the GPU at higher resolutions, as the 4 GB VRAM buffer and 128.1 GB/s bandwidth are insufficient to sustain high fill rates. At 1080p, the data suggests a balanced system, but above that, the GPU’s 43rd percentile standing becomes the dominant factor in frame rate degradation.

Settings Recommendations

The measured rows provide a clear hierarchy for the best experience in Downfall. At 1080p, the Low preset yields 93.8 FPS, which is comfortably above playable thresholds, but the Medium preset still delivers a strong 73.2 FPS while improving visual fidelity. High at 1080p drops to 61.3 FPS, which remains smooth and is likely the optimal balance for most users. Ultra at 1080p is a significant step down to 35.5 FPS, a 42% reduction from High, making it a poor trade-off for the visual gains in a horror game where smoothness is critical for immersion. Moving to 1440p, Low delivers 65.1 FPS, which is playable, but Medium at 54.2 FPS is also viable. High at 1440p falls to 45.4 FPS, which is borderline for a horror title that benefits from responsive controls. Ultra at 1440p is not recommended, as the 29.5 FPS average is below the threshold for consistent frame pacing. At 4K, all presets are compromised. Low at 41.7 FPS is the only option that approaches playability, while Medium at 35.8 FPS and High at 26.4 FPS are marginal. Ultra at 4K produces 18.1 FPS, which is effectively unplayable. Given these results, the data suggests that the best experience is achieved at 1080p High, where the 61.3 FPS average balances visual quality with frame rate stability. For users prioritizing smoothness above all, 1080p Medium at 73.2 FPS is the safer choice, as it provides a 19% improvement over High while retaining decent visual fidelity.

How This Combo Ranks

In Downfall, the combination of the Intel Core i5-9400 and NVIDIA GeForce GTX 1650 ranks 1659 out of 1741 tested combos. This places it in the bottom 5% of all system configurations, indicating that it is a lower-tier pairing for this specific title. The ranking reflects the GPU’s 43rd percentile standing and the CPU’s 50th percentile standing, but the game’s demands at higher resolutions penalize the combo more heavily than the individual component scores might suggest. The data shows that the combo is capable of delivering playable frame rates only at 1080p with reduced settings or at 1440p Low. The rank is consistent with the measured FPS: at 1080p Ultra, the 35.5 FPS result is below the 60 FPS target that most modern titles aim for, and at 4K Ultra, the 18.1 FPS result is a slideshow. The combo’s position among the 1741 configurations suggests that while the CPU is a competent mid-range part, the GTX 1650’s 4 GB VRAM and 128.1 GB/s bandwidth are insufficient for Downfall’s higher preset demands. Relative to the nearest rival GPUs, the GTX 1650 is effectively tied with the RTX 3050 A Mobile, Radeon 550X, and Quadro P2200, which means swapping to any of those would yield negligible improvement. The ranking is a direct consequence of the GPU’s inability to scale beyond 1080p Medium, and it underscores that this combo is best suited for 1080p gaming at medium-to-high settings, where it can still hold its own against more expensive configurations.
