Downfall

The Intel Core i5-10400F paired with the Intel Arc B580 delivers a clear performance hierarchy across the three tested resolutions in Downfall. At 3840x2160, the most demanding preset that sustains an average above the 60 FPS playability threshold is Medium, which records 69.2 FPS. For 2560x1440, the High preset is the most demanding option that stays playable, achieving 87.8 FPS. At 1920x1080, the Ultra preset clears the threshold comfortably with 76.1 FPS, allowing full visual fidelity at the highest tested settings.

Best Settings per Resolution

The database identifies the optimal balance between visual quality and frame rate for each resolution, based on the condition that the average FPS must remain at or above 60.

At 3840x2160, the High preset drops to 54.1 FPS, which falls below the playable threshold. The Ultra preset is even more demanding at 33 FPS. Therefore, the best settings at 4K are Medium, which delivers an average of 69.2 FPS. This provides a comfortable margin above the 60 FPS floor while offering better visual quality than the Low preset, which runs at 79.3 FPS.

Moving to 2560x1440, the situation improves significantly. The High preset achieves 87.8 FPS, making it the most demanding playable setting. The Ultra preset at this resolution drops to 57.9 FPS, just under the 60 FPS target, so it is not recommended for a consistent experience. The Medium preset runs at 108 FPS and Low at 129 FPS, both well above the threshold, but High is the clear choice for maximum quality.

At 1920x1080, all four presets exceed 60 FPS. The Ultra preset averages 76.1 FPS, which is the best visual setting available and remains playable. The High preset reaches 124.3 FPS, Medium hits 148.8 FPS, and Low tops out at 182.7 FPS. For users prioritizing maximum detail, Ultra is the recommended setting at 1080p.

How This Combo Ranks

Within the database of tested combinations, this specific configuration of the Intel Core i5-10400F and Intel Arc B580 ranks 2843 out of 3716 total combos for Downfall. This places it in the lower portion of the overall distribution, specifically around the 23rd percentile of tested systems. The ranking reflects that while the combo can handle the game at multiple resolutions and settings, many other hardware pairings in the database achieve higher absolute frame rates.

The position is largely influenced by the individual components. The CPU, the Intel Core i5-10400F, sits at the 68th percentile among all tested CPUs, indicating it is a mid-to-upper tier processor in general benchmark terms. Similarly, the Intel Arc B580 GPU is at the 68th percentile among all GPUs. Despite both components being near the 68th percentile individually, the combined rank in this specific game is lower than that, which suggests that the game's demands or the pairing's characteristics place it behind a larger number of other combinations.

This rank is not a measure of failure, as the combo still produces playable frame rates at most settings. It does, however, indicate that for Downfall specifically, there are many faster alternatives within the database, particularly at higher resolutions where the GPU becomes the limiting factor.

Measured FPS Breakdown

The recorded data provides average FPS values for each resolution and settings combination, with no minimum or maximum frame time data available in the measurements.

At 3840x2160, the average FPS scales as follows: Low settings produce 79.3 FPS, Medium produces 69.2 FPS, High produces 54.1 FPS, and Ultra produces 33 FPS. The drop from Low to Medium is 10.1 FPS, from Medium to High is 15.1 FPS, and from High to Ultra is 21.1 FPS. The steep decline at the highest settings is typical of a GPU-bound scenario at 4K resolution.

For 2560x1440, the average FPS numbers are: Low at 129 FPS, Medium at 108 FPS, High at 87.8 FPS, and Ultra at 57.9 FPS. The margin between Medium and High is 20.2 FPS, and between High and Ultra is 29.9 FPS. The Ultra preset is the only one that fails to maintain 60 FPS at this resolution.

At 1920x1080, the average FPS figures are: Low at 182.7 FPS, Medium at 148.8 FPS, High at 124.3 FPS, and Ultra at 76.1 FPS. The differences between consecutive presets are 33.9 FPS from Low to Medium, 24.5 FPS from Medium to High, and 48.2 FPS from High to Ultra. The substantial gap between High and Ultra suggests a significant increase in rendering workload when enabling the highest settings.

Across all resolutions, the trend is consistent: lowering settings increases FPS, and the relative impact of each setting tier varies by resolution. At 4K, the High to Ultra transition is the most punishing, while at 1080p, the same transition costs the most frames in absolute terms.

Similar Performance Alternatives

The nearest rivals in the database provide context for what other hardware would deliver similar performance to the components in this pairing.

For the Intel Core i5-10400F, the closest alternatives based on average benchmark scores are the Intel Xeon 6756E, which scores 0.2% higher, and the AMD EPYC 7552, which scores 0.5% higher. On the lower side, the Intel Core 7 160UL scores 0.3% lower, and the AMD Ryzen 3 7320C scores 0.6% lower. These deltas are all within a single percentage point, meaning that in CPU-bound scenarios, these processors would produce nearly identical frame rates to the i5-10400F in Downfall. The practical difference between any of these CPUs is negligible for gameplay, as the variance is far smaller than the FPS differences between graphics presets.

For the Intel Arc B580, the comparable GPUs are the AMD Radeon RX 580 2048SP, which scores 0.2% lower, and the NVIDIA GeForce RTX 3080, which scores 0.7% lower. The NVIDIA GeForce RTX 2080 scores 0.6% higher, and the NVIDIA P106-100 scores 1% higher. These rivals bracket the Arc B580's performance within a narrow band. A system with any of these GPUs paired with a similar CPU would likely produce FPS numbers within a few frames of this combo's results at each resolution and setting. Users considering a build with one of these alternative GPUs can expect comparable playability characteristics, including the same resolution and settings limitations observed here.

CPU and GPU Roles

The data indicates how the workload is distributed between the CPU and GPU across resolutions. The clearest signal comes from the scaling of frame rates as resolution changes.

When comparing the same settings across resolutions, the FPS drops significantly as resolution increases. For example, at High settings, the average FPS is 124.3 at 1920x1080, 87.8 at 2560x1440, and 54.1 at 3840x2160. This represents a 29.4% decrease from 1080p to 1440p and a 38.4% decrease from 1440p to 4K. Such a steep decline with increasing pixel count is characteristic of a GPU-bound workload. The Arc B580 is the primary determinant of frame rates at higher resolutions, as the rendering load scales with resolution.

At 1920x1080, the frame rates are high enough that the CPU's role becomes more relevant. The jump from Low to Medium at 1080p is 33.9 FPS, and from Medium to High is 24.5 FPS, indicating that the GPU still has headroom to render more frames as settings increase. However, the fact that the Ultra preset at 1080p still achieves 76.1 FPS suggests the CPU is not a bottleneck at this resolution; it can feed the GPU adequately even at lower settings where frame rates exceed 180 FPS.

The CPU's performance is better characterized by its general benchmark scores. With a Cinebench R23 multi-core score of 10283 and a single-core score of 1451, the i5-10400F provides solid processing power. Its 3DMark single-thread score of 688 and 2-thread score of 1350 indicate reasonable per-core performance. In Downfall, a horror game that may have varying scene complexity, the CPU is likely sufficient at all tested resolutions, with the GPU being the limiting factor at 4K and for Ultra settings at 1440p.

The resolution scaling also shows that at Low settings, the FPS difference between resolutions is less severe in percentage terms. At Low, the FPS goes from 182.7 at 1080p to 129 at 1440p, a 29.4% drop, and then to 79.3 at 4K, a 38.5% drop from 1440p. This pattern is consistent with the GPU handling the bulk of the work. The CPU's role is to maintain a minimum frame delivery rate, and the data shows that even at 4K Low, the combo reaches 79.3 FPS, which indicates the CPU is not holding back the GPU at lower settings.

The Verdict

The Intel Core i5-10400F and Intel Arc B580 combination is capable of running Downfall with playable performance, defined as an average of 60 FPS or higher, at all three tested resolutions, but with different settings limits.

At 1920x1080, the system is fully capable, running every preset including Ultra at an average of 76.1 FPS. This is the resolution where the combo performs best, with a wide margin above the playable threshold even at maximum settings.

At 2560x1440, the system remains capable but requires a settings cap. The High preset delivers 87.8 FPS, which is a strong result. The Ultra preset fails to maintain 60 FPS at 57.9 FPS, so users should stick to High or below for a consistent experience.

At 3840x2160, the system is limited to Medium settings for playable performance, with 69.2 FPS. The High preset at 54.1 FPS and Ultra at 33 FPS are not recommended for smooth gameplay. For 4K users, Medium is the practical ceiling.

Overall, this combo offers a versatile experience: it excels at 1080p, handles 1440p well with some settings compromises, and can manage 4K only at lower visual presets. The rank of 2843 out of 3716 reflects that while this is not a top-tier combination for Downfall, it still meets the playability standard for a majority of the tested configurations at 1080p and 1440p.
