Downfall

The AMD Ryzen 5 8400F paired with the Intel Arc B580 delivers a strong 1080p experience in Downfall, but struggles to maintain smooth frame rates at 4K with maximum settings. Benchmark measurements show the combo achieves playable performance at 1080p across all tested presets, with the Ultra preset averaging 76 FPS, while 1440p remains highly playable up to High settings at 90.4 FPS. At 4K, the system falls short of the 60 FPS threshold on High and Ultra presets, though Medium settings still deliver a comfortable 69.1 FPS average.

Measured FPS Breakdown

The measured frame rates reveal a clear performance hierarchy across resolutions and settings. At 1920x1080, the combo produces its best results: Low settings average 185.7 FPS, Medium reaches 151.4 FPS, High hits 122 FPS, and Ultra maintains 76 FPS. These numbers indicate the CPU-GPU pairing has ample headroom at Full HD, with even the most demanding preset staying well above the 60 FPS playability threshold.

Moving to 2560x1440, performance scales predictably but retains strong playability. Low settings average 131.3 FPS, Medium drops to 109.3 FPS, and High remains solid at 90.4 FPS. The Ultra preset, however, falls below the playable threshold with an average of 55.1 FPS, showing that the Arc B580's 12 GB frame buffer and 456.0 GB/s bandwidth cannot fully compensate for the increased pixel count at maximum quality.

At 3840x2160, the performance gap becomes more pronounced. Low settings average 82.2 FPS, which is still comfortably playable, while Medium drops to 69.1 FPS, remaining just above the 60 FPS threshold. High settings fall to 56.2 FPS, slightly below playable, and Ultra plummets to 34.4 FPS, making it unsuitable for smooth gameplay. The data shows a consistent pattern: each resolution increase costs roughly 30-40% of the frame rate at equivalent settings, with the Ultra preset being the most demanding across all resolutions.

The lack of min and max FPS data means the analysis relies solely on average frame rates, but the consistency of the scaling between resolutions suggests stable performance rather than erratic spikes. The 1080p Ultra result of 76 FPS compared to 1440p Ultra's 55.1 FPS indicates a 27.5% performance drop, while 1440p to 4K Ultra shows a 37.6% decline, highlighting the GPU's diminishing returns as pixel count grows.

Similar Performance Alternatives

The nearest rivals for the AMD Ryzen 5 8400F show that CPU performance is tightly clustered. The AMD Ryzen 5 7500F posts an average benchmark score of 24964, which is only 0.2% different from the 8400F's score of 25005. The Intel Core i7-11850H scores 24935, a 0.3% delta, while the Intel Core i7-13620H scores 24911, a 0.4% delta. The AMD EPYC 9474F scores 25103, which is 0.4% higher than the 8400F. These margins are negligible in gaming scenarios, meaning any of these CPUs would produce nearly identical frame rates in Downfall when paired with the same GPU.

For the Intel Arc B580, the nearest rivals present a more varied picture. The AMD Radeon RX 580 2048SP scores 23061, just 0.2% above the B580's 23021 average. The NVIDIA GeForce RTX 2080 scores 22895, which is 0.6% lower than the B580, while the RTX 3080 scores 23172, 0.7% higher. The NVIDIA P106-100 scores 23249, 1% above the B580. These small deltas suggest that swapping the B580 for any of these cards would yield nearly identical performance in Downfall, though architectural differences could influence specific settings behavior.

In practical terms, a system built around the Ryzen 5 8400F with any of its nearest CPU rivals would produce the same measured FPS within a rounding error. Similarly, substituting the Arc B580 with an RTX 2080 or RTX 3080 would maintain the same playability classification at each resolution and preset, since a 1% performance difference equates to less than one frame per second in the measured averages.

Best Settings per Resolution

At 1920x1080, the most demanding preset that maintains at least 60 FPS is Ultra, which averages 76 FPS. This is the highest quality setting tested, and the data confirms it remains fully playable. The 1080p resolution allows the combo to run unrestricted, with even the heaviest preset leaving a 16 FPS margin above the playable threshold.

At 2560x1440, the best playable setting is High, averaging 90.4 FPS. The Ultra preset falls short at 55.1 FPS, so High represents the optimal balance between visual quality and performance. The 30.3 FPS gap between High and Ultra at this resolution indicates a steep performance cliff, suggesting that specific Ultra features impose a significant rendering cost.

At 3840x2160, the best playable setting is Medium, averaging 69.1 FPS. Low settings also remain playable at 82.2 FPS, but Medium provides superior visual quality while staying 9.1 FPS above the threshold. High and Ultra both fail to reach 60 FPS, with High at 56.2 FPS and Ultra at 34.4 FPS, making them unsuitable for smooth gameplay at 4K.

CPU and GPU Roles

The performance scaling across resolutions reveals how the CPU and GPU divide responsibilities in Downfall. At 1920x1080, the GPU is the primary constraint, as evidenced by the 185.7 FPS at Low settings versus 76 FPS at Ultra. The 109.7 FPS difference between these presets shows that the Arc B580's rendering workload dominates performance at this resolution, while the Ryzen 5 8400F's 6 cores and 12 threads provide sufficient throughput to avoid bottlenecking.

At 2560x1440, the GPU's role becomes more pronounced. Low settings drop to 131.3 FPS from 185.7 FPS at 1080p, a 29.3% decrease that aligns with the 78% increase in pixel count. The Ultra preset falls from 76 FPS to 55.1 FPS, a 27.5% drop, maintaining a consistent scaling pattern. This indicates the CPU maintains its performance headroom while the GPU struggles with the additional pixel workload, particularly at higher settings where shader complexity increases.

At 3840x2160, the GPU becomes the overwhelming bottleneck. Low settings average 82.2 FPS, which is only 37.4% of the 1080p Low result, despite the 4K resolution requiring four times the pixels. The Ultra preset's 34.4 FPS represents just 45.3% of the 1080p Ultra score. These disproportionate drops suggest that memory bandwidth and pixel fill rate limits, rather than CPU throughput, govern performance at 4K. The Arc B580's 456.0 GB/s bandwidth and 213.6 GPixel/s pixel rate are insufficient for the demands of 4K Ultra in this title.

The data also shows that resolution scaling affects presets differently. From 1080p to 1440p, Low settings lose 29.3% performance, while Ultra loses 27.5%. From 1440p to 4K, Low loses 37.4%, but Ultra loses 37.6%. This nearly identical percentage loss across presets within each resolution step indicates that the GPU's fill rate and bandwidth limits scale uniformly, regardless of visual complexity. The CPU's role remains consistent throughout, as the 8400F's benchmark scores show strong single-thread performance of 2943 in Cinebench R23, which is sufficient for this horror title's likely CPU demands.

How This Combo Ranks

The AMD Ryzen 5 8400F and Intel Arc B580 combination ranks 2792 out of 3716 tested configurations in Downfall, placing it in the 25th percentile of all combos. This ranking reflects the hardware's mid-range positioning: the CPU sits at the 77th percentile among all processors, while the GPU ranks at the 68th percentile among all graphics cards. The combination of two above-average components does not produce an exceptional result in this game, likely due to the GPU's limitations at higher resolutions.

The rank suggests that roughly 75% of tested configurations deliver better performance in Downfall. Given that the GPU's nearest rivals include the RTX 2080 and RTX 3080, which score nearly identically, the bottleneck is not unique to the Arc B580. Instead, the ranking indicates that Downfall is a demanding title that rewards higher-tier GPUs, and this combo's performance aligns with its component tier rather than exceeding it.

In practical terms, the rank means that users with this combo will experience playable performance at 1080p and 1440p across most settings, but will need to compromise at 4K. The 2792nd position out of 3716 combos places it in the bottom third, suggesting that while the hardware meets the minimum requirements for enjoyable gameplay, it does not offer the headroom found in higher-ranked configurations. The combination's strengths are most evident at 1080p, where the 76 FPS Ultra result demonstrates that the CPU and GPU work well together when the GPU is not overburdened by pixel count.
