Downfall

The Intel Core i5-13400F paired with the Intel Arc B580 delivers a wide spread of performance in Downfall, ranging from comfortably playable to outright unplayable depending on how you configure the game. The data shows a clear pattern: at 1080p and 1440p, this combo is a strong performer, while 4K Ultra is the only setting that falls below the 60 FPS playable threshold. The measured FPS numbers paint a precise picture of where this system excels and where it struggles.

Measured FPS Breakdown

At 1920x1080, the combination of the Core i5-13400F and Arc B580 is overwhelmingly fast. The Low preset produces an average of 185 FPS, which is the highest recorded frame rate across all tested configurations. Moving up the settings ladder, Medium drops to an average of 151 FPS with a minimum of 128 FPS and a maximum of 174 FPS. High settings still deliver a strong 124 FPS average. Even the most demanding Ultra preset at 1080p maintains an average of 77 FPS, which is well above the 60 FPS playable threshold. This resolution is clearly the sweet spot for this hardware, with every preset offering headroom.

Stepping up to 2560x1440, performance remains robust but begins to show the expected scaling penalty. The Low preset averages 132 FPS, which is a 29% reduction from the 1080p Low result. Medium settings average 108 FPS, with a minimum of 92 FPS and a maximum of 124 FPS, keeping the experience smooth. High settings average 88 FPS, still comfortably above 60 FPS. The Ultra preset, however, falls to an average of 55 FPS, which is below the playable threshold. This marks the first instance where the hardware cannot maintain a consistent 60 FPS, although the drop is modest at just 5 FPS below the target.

At 3840x2160, the performance curve steepens significantly. The Low preset averages 82 FPS, which is still playable and represents a 38% drop from the 1080p Low figure. Medium settings average 67 FPS, with a minimum of 57 FPS and a maximum of 77 FPS, placing it just barely above the 60 FPS threshold. High settings fall to 55 FPS, and Ultra drops further to 34 FPS. The 4K Ultra setting is the only configuration in the entire dataset that is clearly unplayable, showing a severe performance cliff that suggests the GPU is running out of memory bandwidth or shading power at this extreme resolution.

CPU and GPU Roles

The benchmark results indicate that the Intel Arc B580 is the primary bottleneck in Downfall, but only at higher resolutions and presets. The scaling between resolutions is telling: from 1080p Low to 1440p Low, the average FPS drops from 185 to 132, a 29% decrease. From 1440p Low to 4K Low, the average drops from 132 to 82, a 38% decrease. This progressive degradation points to the GPU becoming increasingly saturated as pixel count rises.

At 1080p, the Core i5-13400F appears to have ample headroom. The jump from Low to Ultra at this resolution only reduces average FPS from 185 to 77, a 58% reduction, which is entirely attributable to GPU workload increases. The CPU, with its 10 cores and 16 threads, does not appear to be limiting performance at any preset in this resolution. The 3DMark scores support this: the processor achieves 7,314 in the 16-thread test and 7,307 in the max-thread test, showing strong multi-core capability that is more than sufficient for a horror title like Downfall.

At 1440p and 4K, the GPU's role becomes dominant. The 4K Ultra result of 34 FPS is a 56% drop from the 1440p Ultra result of 55 FPS, and a 78% drop from the 1080p Ultra result of 77 FPS. This steep curve is characteristic of a GPU that is hitting its memory bandwidth ceiling—the Arc B580's 456.0 GB/s bandwidth and 12 GB GDDR6 memory are being taxed heavily at 4K. The CPU's role diminishes at these higher resolutions, as the frame rate becomes increasingly governed by the GPU's shading units and ROPs.

How This Combo Ranks

The Core i5-13400F and Arc B580 combination ranks at 2802 out of 3716 tested combos in Downfall. This places it in the 75th percentile of all configurations tested, meaning roughly a quarter of all combos perform better. Given that this is a 2023 CPU paired with a 2024 GPU, the rank is respectable but not top-tier. The game itself is from 2016, which means it is not particularly demanding by modern standards, so the hardware should be expected to perform well.

The percentile data reinforces this assessment. The CPU sits at the 77th percentile against all CPUs, and the GPU sits at the 68th percentile against all GPUs. When combined, the system performs slightly below what the individual component percentiles would suggest, indicating that the GPU is the limiting factor in this specific game. The 4K Ultra result of 34 FPS is the primary drag on the combo's overall rank, as it represents a significant failure point that drags down the average across all settings and resolutions.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-13400F provide a clear picture of what other CPUs would deliver similar results. The AMD Ryzen 9 6900HS has an average benchmark score of 25,284, which is essentially identical to the i5-13400F's 25,292, a delta of 0%. The Intel Core 5 120 scores 25,362, which is 0.3% higher, and the AMD Ryzen 5 5600X3D scores 25,365, also 0.3% higher. The AMD Ryzen 7 6800H scores 25,201, which is 0.4% lower. In practice, any of these processors would produce nearly indistinguishable frame rates in Downfall, as the game is not CPU-bound at most settings.

For the GPU side, the nearest rivals to the Intel Arc B580 include the AMD Radeon RX 580 2048SP with an average score of 23,061, which is 0.2% lower than the Arc B580's 23,021. The NVIDIA GeForce RTX 2080 scores 22,895, which is 0.6% lower, and the NVIDIA GeForce RTX 3080 scores 23,172, which is 0.7% higher. The NVIDIA P106-100 scores 23,249, 1% higher. These deltas are all within 1%, meaning that swapping the Arc B580 for any of these cards would result in nearly identical performance in Downfall. The RTX 3080 would offer a marginal improvement at 4K Ultra, potentially pushing that 34 FPS result closer to 40 FPS, but it would not fundamentally change the playability picture.

The Verdict

This PC can run Downfall successfully, but the experience varies dramatically by resolution and settings. At 1920x1080, the system clears the 60 FPS threshold on every preset, including Ultra at 77 FPS average. This is the ideal resolution for maxed-out visuals. At 2560x1440, the system remains playable on High (88 FPS), Low (132 FPS), and Medium (108 FPS), but Ultra falls to 55 FPS and should be avoided. At 3840x2160, only Low (82 FPS) and Medium (67 FPS) are playable, with High at 55 FPS and Ultra at 34 FPS failing the threshold.

The Intel Arc B580 is clearly the limiting factor at higher resolutions. The 4K Ultra result of 34 FPS is a dramatic drop that indicates the GPU's 13.67 TFLOPS of FP32 performance and 456.0 GB/s bandwidth are insufficient for this demanding configuration. However, for a 2016 horror game, the system offers more than enough power for the vast majority of play scenarios. The Core i5-13400F never appears to be a bottleneck, and the GPU handles 1080p and 1440p with ease. For the best balance of visual quality and performance, 1440p High is the recommended configuration, delivering an 88 FPS average that is smooth and stable.
