Downfall

The Intel Core i5-11400F paired with the Intel Arc B580 presents a compelling 1080p and 1440p configuration for Downfall, with the data showing a clear performance ceiling that shifts depending on resolution. This analysis breaks down the measured results, focusing on where this combo excels and where its limitations become apparent.

Resolution Scaling

The performance drop from 1080p to 4K in Downfall is steep and tells a clear story about which component is driving the experience. At 1080p with Low settings, the combo produces an average of 184.8 FPS, which drops to 82.7 FPS at 4K — a reduction of roughly 55%. This scaling pattern is typical of a system that becomes increasingly GPU-bound at higher resolutions. The 1080p results, particularly at Low and Medium settings, show frame rates well above 144 FPS, suggesting the CPU and GPU are working in concert without a single bottleneck dominating.

Moving to 1440p, the average FPS at High settings is 91.1, compared to 124 FPS at 1080p High. That’s a 26.5% drop for a 78% increase in pixel count, indicating the GPU is still managing the load effectively. However, the 4K results reveal the Arc B580’s limits. At 4K Ultra, the average FPS falls to 31.8, which is barely playable for a horror title where smooth motion matters for atmosphere. The 4K High setting fares better at 57.4 FPS, but the pattern is clear: this combo is best suited for 1080p and 1440p gaming, with 4K reserved for lower presets or less demanding scenes.

The delta between Low and Ultra settings at each resolution also highlights GPU scaling. At 1080p, the gap is 105.3 FPS (184.8 vs 79.5), while at 4K the gap narrows to 50.9 FPS (82.7 vs 31.8). This compression at higher resolutions suggests the CPU is not the primary constraint at 4K; the GPU simply runs out of headroom. For a 6-core, 12-thread processor with a 4.40 GHz boost clock, the i5-11400F provides enough throughput to keep feeding the Arc B580 at lower resolutions, but the GPU becomes the limiting factor as pixel count rises.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor built on the Rocket Lake architecture, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. Its 12 MB of shared L3 cache and dual-channel DDR4 memory support (with 51.2 GB/s bandwidth) are adequate for feeding a mid-range GPU like the Arc B580. In synthetic tests, the CPU scores 14372 in Cinebench R23 multicore and 2029 in single-core, which positions it as a capable mid-range part. The 3DMark results show a scaling pattern from 1691 (2 threads) to 5652 (max threads), indicating good multi-threaded scaling for a 6-core part.

In Downfall, the CPU’s role becomes evident in the frame rate differences between resolution settings. At 1080p Low, the 184.8 FPS average suggests the CPU can push high frame rates when the GPU is not stressed. The drop to 79.5 FPS at 1080p Ultra is more attributable to GPU load than CPU limits, as the 4.40 GHz boost clock provides sufficient single-thread performance for a 2016 horror title. The 3DMark single-thread score of 868 and PassMark single-thread score of 2981 confirm that this chip handles lightly threaded workloads well, which is typical for game logic in titles like Downfall.

However, the CPU’s 65 W TDP and 14 nm process node mean it is not a powerhouse by modern standards. Its percentile rank of 75 versus all CPUs is respectable, but the nearest rivals — including the AMD Ryzen 7 5700U and Intel Core i7-1260P — show that the i5-11400F is competitive but not dominant in its class. For Downfall, the CPU is sufficient to avoid being the primary bottleneck at 1080p and 1440p, but it does not provide the overhead needed to compensate for the GPU’s limitations at 4K Ultra.

How This Combo Ranks

The combo of the Intel Core i5-11400F and Intel Arc B580 ranks 1342 out of 1741 tested configurations for Downfall. This places it in the lower 23% of all combos, which might seem underwhelming on the surface. However, the ranking is heavily influenced by 4K performance, where the combo struggles. At 1080p and 1440p, the measured frame rates are competitive with many higher-ranked setups, but the database ranking weights all resolutions equally.

The GPU’s percentile rank of 66 against all GPUs is notably lower than the CPU’s 75th percentile, suggesting the graphics card is the weaker link in this pairing. The Arc B580’s nearest rival, the NVIDIA GeForce RTX 4060, scores 23181 (0.7% higher), which is a marginal difference. Yet, in Downfall, the combo’s rank suggests that other pairings with similar GPU scores but stronger CPUs may achieve higher overall scores in this specific title. The CPU’s nearest rivals all have average scores within 0.2% of the i5-11400F, so the CPU is not the differentiating factor in the combo ranking.

What this means for a builder is that the combo is solid for 1080p and 1440p gaming, but it will not top any charts. The rank of 1342 reflects a mid-tier system that delivers playable frame rates in most scenarios, with 4K Ultra being the only clearly unacceptable setting. Compared to the 1741 total combos, this setup sits in the middle, which aligns with its component tier.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings presets, providing a complete picture of performance.

At 1920x1080, the combo delivers its best results. Low settings produce an average of 184.8 FPS, Medium reaches 148.2 FPS, High hits 124 FPS, and Ultra drops to 79.5 FPS. The gap between Low and Ultra is 105.3 FPS, showing that settings have a significant impact at this resolution. For a horror game, 124 FPS at High is excellent, and even 79.5 FPS at Ultra is playable, though not ideal for fast-paced scenes.

At 2560x1440, the performance scales down predictably. Low averages 131.6 FPS, Medium 105.2 FPS, High 91.1 FPS, and Ultra 54.8 FPS. The drop from 1080p to 1440p at High settings is 32.9 FPS (26.5%), which is reasonable. Ultra at 1440p falls below 60 FPS, making it a borderline choice for smooth gameplay.

At 3840x2160, the GPU becomes the clear limiting factor. Low averages 82.7 FPS, Medium 69.7 FPS, High 57.4 FPS, and Ultra 31.8 FPS. The 4K Ultra result is the only one in the entire dataset that falls below 30 FPS, and even 4K High at 57.4 FPS is marginal. For 4K gaming, only Low and Medium settings are viable, with Medium providing a 69.7 FPS average that is acceptable for a slower-paced horror title.

Settings Recommendations

Based on the measured data, the optimal settings depend on your target resolution and refresh rate.

For 1080p gaming, High settings at 124 FPS is the best balance of visual quality and performance. If you have a 144 Hz monitor, Medium at 148.2 FPS is also a strong choice, offering a 24.2 FPS improvement over High with only a modest visual downgrade. Ultra at 79.5 FPS is not recommended for fast-paced sections, but it is playable for those who prioritize visual fidelity over frame smoothness.

For 1440p, High settings at 91.1 FPS is the clear recommendation. It stays above the 60 FPS threshold with headroom, and the visual quality is sufficient for a horror game. Medium at 105.2 FPS is even smoother, but the difference between High and Medium is less critical at this resolution. Ultra at 54.8 FPS dips below 60, making it a less desirable choice unless you are willing to accept occasional frame drops during intense scenes.

For 4K, the data suggests that Medium settings at 69.7 FPS is the best option, as it maintains playability while offering better visuals than Low. High at 57.4 FPS is borderline, and Ultra at 31.8 FPS should be avoided entirely. If you are targeting 4K, stick with Medium or Low to keep the experience fluid.

In summary, this combo is best utilized at 1080p High or 1440p High, where it delivers frame rates that suit both 60 Hz and higher refresh displays. Lowering to Medium can provide extra headroom for competitive play, while Ultra is only viable at 1080p. The Arc B580’s 12 GB of VRAM is sufficient for all tested settings, but its raw compute power limits 4K Ultra performance.
