Downfall

The Intel Core i5-10400F and Intel Arc B570 pairing delivers a playable experience in Downfall, but the data clearly indicates that the graphics card is the primary constraint at higher resolutions and settings. The combination ranks in the 80th percentile among tested systems, showing that while this is not a top-tier hardware pairing, it consistently outperforms a significant majority of other configurations. The measured results show a system that can handle 1080p and 1440p gaming with ease, yet struggles to maintain fluid frame rates at 4K with maximum settings.

Resolution Scaling

The performance drop from 1080p to 4K is dramatic and reveals the GPU-bound nature of this pairing. At High settings, the average frame rate falls from 109 FPS at 1920x1080 to 78 FPS at 2560x1440, a reduction of 31 FPS. Moving to 4K, the average drops further to 49 FPS, which represents a 55% decrease from the 1080p baseline. This steep scaling curve indicates that the Intel Arc B570's rendering throughput becomes the limiting factor as pixel count increases.

The scaling behavior varies significantly across different quality presets. At Low settings, the system achieves 163 FPS at 1080p, which is remarkably high, but this falls to 116 FPS at 1440p and 72 FPS at 4K. The 4K Low result is still respectable, suggesting that the GPU retains enough headroom to push acceptable frame rates when graphical demands are reduced. The Medium preset tells a similar story: 133 FPS at 1080p, 95 FPS at 1440p, and 59 FPS at 4K, with the 4K result including a minimum frame rate of 50 FPS.

Ultra settings expose the most severe scaling penalty. The average frame rate plummets from 68 FPS at 1080p to 49 FPS at 1440p, and finally to just 30 FPS at 4K. This 4K Ultra result is below the threshold for smooth gameplay, confirming that this setting combination is not viable. The gap between 1080p and 1440p Ultra is 19 FPS, while the gap between 1440p and 4K Ultra is also 19 FPS, showing a consistent degradation pattern.

The frame rate drops are proportionally larger when moving from 1440p to 4K compared to 1080p to 1440p. At High settings, the 1080p to 1440p drop is 31 FPS, while the 1440p to 4K drop is 29 FPS, nearly identical. However, in percentage terms, the 4K step costs 37% of the 1440p performance, while the 1440p step costs 28% of the 1080p performance. This accelerating decline is typical of a GPU that is approaching its memory bandwidth or pixel fill rate limits.

The data suggests that 1080p is the sweet spot for this combination, where the Core i5-10400F can keep the Arc B570 adequately fed. At 4K, the GPU is clearly the bottleneck, as even the Low preset cannot achieve 60 FPS, while the 1080p Low preset reaches 163 FPS. The scaling from Low to Ultra at each resolution shows that the GPU's compute units and memory subsystem are the deciding factors, not the CPU's six cores.

CPU Role

The Intel Core i5-10400F provides a solid foundation with its 6 cores and 12 threads, running at a base clock of 2.90 GHz and a boost clock of 4.30 GHz. This Comet Lake processor, built on a 14 nm process, delivers benchmark scores that place it in the 68th percentile of all CPUs, indicating it is a mid-range performer. The multi-threaded results are strong, with Cinebench R23 scoring 10283 points and Geekbench multicore scoring 6257, showing that the CPU can handle well-threaded workloads.

For a horror game like Downfall, which typically relies on consistent frame pacing rather than extreme thread counts, the 12 threads provide ample headroom. The 3DMark 16-thread score of 4748 and max-thread score of 4735 are nearly identical, showing that the processor scales well up to its full thread count. The single-thread performance, however, is more modest, with a 3DMark single-thread score of 688 and a Cinebench R23 single-core score of 1451, which places it behind more modern architectures.

The CPU's memory bandwidth of 42.7 GB/s over dual-channel DDR4 is adequate but not exceptional. In 1080p gaming, where the CPU has more influence on frame rates, the system achieves 163 FPS at Low settings, indicating that the processor is not holding back the GPU in less demanding scenarios. The 3DMark 2-thread score of 1350 shows that even with fewer threads active, the CPU can maintain reasonable performance for games that depend on lower thread counts.

At 1440p and 4K, the CPU's role diminishes as the GPU becomes the bottleneck. The fact that the 4K Low preset (72 FPS) is more than double the 4K Ultra preset (30 FPS) demonstrates that the GPU's workload, not CPU throughput, determines the outcome. The Core i5-10400F's 12 MB of shared L3 cache is sufficient for this game's data patterns, and the 65W TDP suggests it can sustain boost clocks without thermal throttling, though the data does not include temperature measurements.

The nearest rivals to the Core i5-10400F include the Intel Xeon 6756E with a 0.2% higher average score, the Intel Core 7 160UL with a 0.3% lower score, the AMD EPYC 7552 with a 0.5% higher score, and the AMD Ryzen 3 7320C with a 0.6% lower score. These differences are negligible, meaning the CPU's performance class is well established, and in Downfall, it is unlikely to be the deciding factor between playable and unplayable frame rates.

GPU Role

The Intel Arc B570 is the star of this show, and its specifications explain the observed performance. With 2304 shading units, 144 texture mapping units, and 80 raster output units, the GPU offers substantial parallel processing capability. The 10 GB of GDDR6 memory on a 160-bit bus provides 380.0 GB/s of bandwidth, which is critical for high-resolution textures and effects. The boost clock of 2500 MHz is constant, and the 11.52 TFLOPS of FP32 compute power is respectable for a mid-range card.

The GPU's memory capacity and bandwidth are the key factors in 4K performance. At 4K High, the system hits 49 FPS, which is just below the 60 FPS target. The 10 GB frame buffer is likely sufficient for this game's textures, but the 380.0 GB/s bandwidth may be the limiting factor when rendering at 3840x2160. The 200.0 GPixel/s pixel rate and 360.0 GTexel/s texture rate indicate the GPU can fill pixels quickly, but the memory subsystem must keep up.

The Arc B570's benchmark scores place it in the 65th percentile of all GPUs, with a Passmark G3D score of 14195 and a 3DMark Steel Nomad score of 2649. The nearest rivals include the NVIDIA GeForce RTX 3070 Mobile (0.1% higher), the Intel Arc A750 (0.1% lower), the NVIDIA Quadro M4000M (0.4% higher), and the AMD Radeon R9 M390X (0.5% lower). These close scores suggest the Arc B570 performs at a consistent level across various titles, but Downfall's specific demands reveal its limits.

The GPU's 18 ray tracing cores and support for DirectX 12 Ultimate suggest it is future-proofed, but these features may not be heavily utilized in a 2016 horror game. The 150W TDP and dual-slot design are standard, and the PCIe 4.0 x8 interface provides sufficient bandwidth for most scenarios. The 19,600 million transistors on a 272 mm² die show a dense architecture that balances power and efficiency.

In Downfall, the GPU's performance scaling from Low to Ultra settings is linear at each resolution. At 1080p, the gap from Low (163 FPS) to Ultra (68 FPS) is 95 FPS, while at 4K, the gap is 42 FPS. This suggests that the GPU has enough compute power to handle lower settings easily, but the increased shader and memory load at Ultra settings quickly saturates the available resources. The 4K Medium result of 59 FPS with a minimum of 50 FPS shows that moderate settings are the practical ceiling for 4K gaming.

How This Combo Ranks

The Intel Core i5-10400F and Intel Arc B570 combination ranks 2343 out of 2928 tested combos in Downfall, putting it in the 21st percentile of all systems. This ranking reflects the mid-range nature of both components; the CPU is in the 68th percentile and the GPU in the 65th percentile, but their combined performance in this specific game is lower than their individual standings would suggest. This discrepancy indicates that Downfall is demanding on the graphics subsystem, and the Arc B570's limitations at high settings drag the overall ranking down.

Despite the low ranking, the actual frame rates are far from unplayable. At 1080p, every preset except Ultra exceeds 100 FPS, and even Ultra hits 68 FPS. At 1440p, High and Medium presets stay above 75 FPS, and only Ultra drops below 50 FPS. The 4K results are weaker, but the Low preset still manages 72 FPS. This suggests that the ranking includes many systems with much more powerful GPUs, but for a mid-range build, this combo performs admirably in most scenarios.

The gap between this combo and higher-ranked systems is likely due to the GPU's 10 GB memory and 160-bit bus, which limit 4K performance. The Core i5-10400F's 12 threads are sufficient, but its single-thread score of 688 in 3DMark may hold back frame rates in CPU-bound scenes at 1080p. The combination's ranking is consistent with its component percentiles, showing that neither part is severely over- or under-performing relative to its peers.

For users considering this combo, the ranking should be interpreted as a warning for 4K Ultra gaming, but a confirmation that 1080p and 1440p are well within reach. The system is not competitive with top-tier builds, but it is far from the bottom of the barrel, and the measured data shows it can deliver a satisfying experience in Downfall with appropriate settings.

Settings Recommendations

The measured FPS data provides clear guidance for optimizing the experience in Downfall. At 1920x1080, the High preset offers the best balance of visual quality and performance, delivering 109 FPS average. This leaves headroom for demanding scenes, and the 163 FPS Low result shows the system can far exceed display refresh rates if needed. For players with 60Hz monitors, the High preset is ideal, while those with 144Hz displays can use Medium (133 FPS) for a smoother experience.

At 2560x1440, the High preset is the recommended choice, with 78 FPS average. The Medium preset at 95 FPS offers a better frame rate with a slight visual compromise, making it suitable for competitive play or fast-paced horror sequences. The Low preset at 116 FPS is overkill for most displays, but it ensures maximum frame pacing. The Ultra preset at 49 FPS should be avoided, as it falls below the 60 FPS threshold and may introduce stutter in tense moments.

For 4K gaming, the Medium preset is the only viable option, with 59 FPS average and a 50 FPS minimum. This provides a playable experience, though the occasional dips below 60 FPS may be noticeable. The Low preset at 72 FPS is smoother but sacrifices visual fidelity, which is a trade-off in a horror game where atmosphere matters. The High preset at 49 FPS is borderline, and Ultra at 30 FPS is unplayable.

The data supports a tiered approach: use High settings at 1080p and 1440p for the best experience, and drop to Medium at 4K. The 1440p Medium preset, with its 81 FPS minimum, is the most consistent performer across all resolutions, suggesting it is the sweet spot for this hardware. The 1080p Medium preset, with a 113 FPS minimum, is the best choice for high-refresh-rate displays. Avoid Ultra settings at any resolution above 1080p, as the frame rate penalty is severe.
