CPU and GPU Roles

The measured FPS data across resolutions and presets reveals how the workload shifts between the AMD Ryzen 5 8400F and the Intel Arc B370. At 1920x1080, the system shows strong scaling from Low to Medium to High, with average FPS dropping from 96 to 78 to 64. This progression suggests the GPU handles the rendering load capably at this resolution, while the CPU provides sufficient frame pacing. The jump to Ultra at 1080p cuts the average FPS to 40, a 37.5% reduction from High, indicating that the GPU's shading units and texture units become the limiting factor when the most demanding preset is enabled.

Moving to 2560x1440, the pattern shifts. Low settings produce 68 FPS average, which clears the playable threshold. Medium drops to 56 FPS, and High falls to 46 FPS. The delta between Low and Medium at 1440p is 12 FPS, whereas at 1080p the same delta is 18 FPS. This wider gap at lower resolution points to the CPU having more headroom at 1080p, allowing the GPU to stretch its performance. At 1440p, the GPU's 20 ROPs and 40 TMUs begin to constrain output, and the system shared memory architecture for the GPU adds latency that becomes more visible as pixel count increases.

At 3840x2160, the GPU becomes the dominant bottleneck. Low settings average 43 FPS, Medium averages 35 FPS, and High drops to 29 FPS. The scaling from Low to Medium to High at 4K is nearly linear, with each step costing roughly 7 to 8 FPS. This linear degradation indicates the GPU is saturated and the CPU is no longer contributing meaningfully to frame rate differences. The Ultra preset at 4K collapses to 18 FPS, a 58% drop from Low, which confirms that the Arc B370's 6.144 TFLOPS FP32 throughput cannot sustain the pixel and texture load at this resolution.

The CPU's role is more prominent at lower resolutions. The Ryzen 5 8400F, with its 6 cores and 12 threads, has enough compute capacity to feed the GPU at 1080p. The single-thread score of 951 in 3DMark and 3685 in PassMark indicates solid per-core performance for a game like Downfall, which relies on physics and AI calculations typical of horror titles. However, the CPU's 16 MB shared L3 cache and dual-channel DDR5 memory bandwidth of 83.2 GB/s become less relevant as resolution increases because the GPU's memory access pattern dominates. The data suggests that at 4K, the GPU's system shared memory and 25 W TDP limit performance, not the CPU.

Measured FPS Breakdown

At 1920x1080, the recorded data shows a clear hierarchy. Low settings deliver 96 FPS average, Medium delivers 78 FPS with a minimum of 67 and maximum of 90, High delivers 64 FPS, and Ultra delivers 40 FPS. The Medium preset shows the only min/max range recorded for this resolution, indicating frame pacing variability between 67 and 90 FPS. The gap between Medium and High is 14 FPS, while the gap between High and Ultra is 24 FPS, suggesting that Ultra introduces rendering features that disproportionately impact the GPU.

At 2560x1440, Low settings produce 68 FPS average, which is the only playable result at this resolution. Medium averages 56 FPS with a minimum of 48 and maximum of 64, High averages 46 FPS, and Ultra averages 29 FPS. The Medium preset at 1440p shows a min/max range of 16 FPS, similar to the 23 FPS range at 1080p Medium, indicating consistent frame time variance. The drop from Low to Medium at 1440p is 12 FPS, and from Medium to High is 10 FPS, while High to Ultra costs 17 FPS. This progressive decline highlights the GPU's texture fill rate limitations.

At 3840x2160, Low settings average 43 FPS, Medium averages 35 FPS with a minimum of 30 and maximum of 40, High averages 29 FPS, and Ultra averages 18 FPS. The Medium preset at 4K shows a 10 FPS range between minimum and maximum, which is the tightest recorded range across all resolutions for Medium settings. This suggests that at 4K, the system reaches a steady state where the GPU is consistently saturated. The 4K Low to Medium delta is 8 FPS, Medium to High is 6 FPS, and High to Ultra is 11 FPS. The Ultra preset at 4K is effectively unplayable, matching the 1080p Ultra result in relative terms but at a much lower absolute frame rate.

The min/max data points available in the database provide insight into frame consistency. At 1080p Medium, the system fluctuates between 67 and 90 FPS, a variance that stays above the 60 FPS threshold. At 1440p Medium, the range is 48 to 64 FPS, meaning the minimum dips below playable. At 4K Medium, the range is 30 to 40 FPS, never approaching playable. These numbers indicate that even when average FPS clears 60, the user should check minimums to ensure no sustained drops occur.

Similar Performance Alternatives

The nearest rivals for the AMD Ryzen 5 8400F, based on average benchmark scores, are all within 0.4% of its 25005 score. The AMD Ryzen 5 7500F sits at 24964, making it functionally equivalent for gaming workloads. The Intel Core i7-11850H and Intel Core i7-13620H score 24935 and 24911 respectively, placing them in the same performance tier. The AMD EPYC 9474F scores 25103, slightly higher, but its server-oriented design would not change game performance meaningfully for a title like Downfall. Any of these CPUs would produce nearly identical frame rates when paired with the same GPU.

For the Intel Arc B370, the nearest rivals are older discrete and mobile graphics solutions. The ATI Mobility Radeon HD 5570 scores 1186, the ATI Radeon HD 5770 scores 1190, and the AMD Radeon HD 7650M scores 1192. These are within 0.7% of the Arc B370's 1184 score. The AMD FirePro M2000 scores 1168, which is 1.4% lower. This proximity suggests that swapping the Arc B370 for any of these GPUs would yield similar Downfall frame rates. However, the Arc B370's lack of dedicated VRAM and reliance on system shared memory may introduce latency that the older discrete GPUs would not have, even if their raw 3DMark scores are similar.

When considering a full system alternative, the data implies that pairing the Ryzen 5 8400F with any of these rival GPUs would produce results within a few FPS of the measured values. The 1080p High preset at 64 FPS would likely remain playable, while 1440p Low at 68 FPS would also hold. The 4K results would remain unplayable regardless of which rival GPU replaced the Arc B370, as all four rivals have similar or lower scores.

The Verdict

The verdict data from the database is clear. This PC can run Downfall at 1920x1080 with High, Medium, or Low settings, all of which exceed the 60 FPS threshold. The best playable setting at 1080p is High, which averages 64 FPS. At 2560x1440, only Low settings clear 60 FPS, averaging 68 FPS. At 3840x2160, no settings achieve playable frame rates; the best result is Low at 43 FPS average, which falls 17 FPS short of the threshold.

The 1080p results indicate a comfortable experience for most of the preset range. Medium settings provide a 78 FPS average with a minimum of 67, which keeps the experience smooth even during moments when the game loads new areas or spawns enemies. High settings at 64 FPS average leave less headroom, but the database shows no min/max data for High, so the user cannot verify whether dips occur below 60. Ultra at 1080p is not playable at 40 FPS, making it a clear avoid.

At 1440p, the system is borderline. Low settings at 68 FPS average work, but Medium drops to 56 FPS with a minimum of 48, which would cause noticeable stuttering in a horror game where smooth camera movement matters. The data suggests that users with 1440p monitors should stick to Low settings. At 4K, the system is not viable for playable frame rates. The 43 FPS Low result and 35 FPS Medium result both fall short, and the 18 FPS Ultra result is a slideshow.

How This Combo Ranks

The combo rank for this specific CPU and GPU pairing in Downfall is 3429 out of 3716 tested combinations. This places it in the bottom 8% of all recorded configurations. The low rank is primarily driven by the GPU's limited capabilities, as the CPU ranks in the 77th percentile among all CPUs. The Arc B370 sits in the 5th percentile among all GPUs, which drags the overall combo ranking down significantly. The database shows that many other tested combinations, likely featuring more powerful discrete GPUs, achieve far higher frame rates in this game. For a horror title that benefits from consistent frame pacing to maintain atmosphere, this rank indicates that users should not expect a high-end experience. The 1080p playable results are a positive outlier given the GPU's low percentile ranking, but the system overall sits near the bottom of tested hardware.

Best Settings per Resolution

For 1920x1080, the most demanding preset that stays at or above 60 FPS is High, with an average of 64 FPS. Medium also works at 78 FPS, but High offers better visual quality while still clearing the threshold. The database lists High as the best settings choice for this resolution.

For 2560x1440, the only preset that maintains 60 FPS or higher is Low, averaging 68 FPS. Medium drops to 56 FPS, which is below the threshold. The database confirms Low as the best settings choice for 1440p.

For 3840x2160, no preset achieves 60 FPS. The database records no playable settings and no best settings for this resolution. Users with 4K displays would need to reduce resolution or accept frame rates below 40 FPS. The highest average at 4K is 43 FPS on Low, which is still not playable by the 60 FPS standard used in this analysis. The data does not support any 4K configuration for this game with this hardware.
