Downfall

The AMD Ryzen 5 7500F paired with the Intel Arc B390 in Downfall presents a dataset that is heavily skewed by the GPU’s performance ceiling. The measured frames per second (FPS) across all resolutions and settings indicate that this combination is firmly entry-level for this horror title, with the integrated-class Arc B390 acting as the primary constraint. The following analysis breaks down the measured data to determine optimal settings, scaling behavior, and the respective roles of the CPU and GPU.

Settings Recommendations

Based on the measured FPS rows, the most effective experience is achieved at 1920x1080 with Low settings, which delivers an average of 106 FPS. This is the only tested configuration that crosses the 100 FPS threshold, providing a smooth and responsive baseline for a game where reaction time can be critical. The data shows a clear progression: at 1080p, lowering settings from Ultra to Low yields a substantial gain from 44 FPS to 106 FPS, a jump of 62 FPS. This suggests that the GPU is heavily taxed by the higher visual fidelity presets.

For users prioritizing visual quality over raw frame rate, 1920x1080 with Medium settings offers a balanced compromise, producing an average of 87 FPS with a minimum of 74 FPS and a maximum of 100 FPS. This preset maintains playability while improving on the Low preset’s visuals. The High preset at 1080p drops to 71 FPS average, which is still playable but begins to show the GPU’s strain. Pushing to Ultra at 1080p, however, results in a significant performance hit to 44 FPS, which is below the threshold for smooth gameplay.

At higher resolutions, the trade-offs become more severe. 2560x1440 with Low settings is the only viable option at that resolution, producing an average of 76 FPS. Moving to Medium at 1440p drops the average to 62 FPS, with a minimum of 53 FPS, which may introduce noticeable stutter in intense scenes. The High preset at 1440p yields 51 FPS, and Ultra falls to 32 FPS, making both less desirable for consistent play. At 3840x2160, even the Low preset only manages an average of 47 FPS, which is marginal, while Medium drops to 39 FPS and High to 32 FPS. The Ultra preset at 4K is effectively unplayable at 20 FPS.

The data suggests that the best experience per the measured rows is unequivocally 1080p Low, given its high average FPS. However, for those who can tolerate lower frame rates for better visuals, 1080p Medium is the highest quality preset that maintains an average above 60 FPS. The recommendation is to prioritize 1080p and avoid Ultra presets at any resolution, as they consistently result in sub-60 FPS averages.

Resolution Scaling

The FPS data from 1080p to 4K reveals a consistent and steep decline in performance, confirming that the Intel Arc B390 is the limiting component. At Low settings, the average FPS drops from 106 at 1920x1080 to 76 at 2560x1440, a reduction of 30 FPS. Moving to 3840x2160, the average further drops to 47 FPS, another 29 FPS reduction. This shows that the GPU’s rendering capabilities are severely taxed by the increase in pixel count, with the frame rate nearly halving from 1080p to 4K.

The pattern is similar across all settings. For Medium, the average FPS goes from 87 at 1080p to 62 at 1440p, then to 39 at 4K. For High, it goes from 71 at 1080p to 51 at 1440p, then to 32 at 4K. The Ultra preset shows the most dramatic drop, from 44 at 1080p to 32 at 1440p, and finally to 20 at 4K. The consistency of these drops, roughly 25-30 FPS between 1080p and 1440p, and another 20-30 FPS between 1440p and 4K, indicates a linear scaling with pixel count, which is characteristic of a GPU-bound scenario.

The data implies that the CPU, the AMD Ryzen 5 7500F, is not the bottleneck at any resolution. If the CPU were limiting, the frame rates would plateau or show smaller differences at higher resolutions. Instead, the steady decline suggests that the Arc B390’s fill rate and shader throughput are being exhausted by the increased resolution. This is further supported by the fact that the GPU’s pixel rate is 60.00 GPixel/s, which is low for modern standards. The scaling behavior strongly suggests that for this title, resolution is the primary factor determining performance, and the GPU is the sole constraint.

Measured FPS Breakdown

At 1920x1080, the measured FPS values show a clear hierarchy. The Low preset delivers an average of 106 FPS, which is the highest recorded for this combo. The Medium preset averages 87 FPS, with a minimum of 74 and a maximum of 100. High settings produce an average of 71 FPS. The Ultra preset is the most demanding, dropping to an average of 44 FPS. This 62 FPS difference between Low and Ultra at 1080p highlights the GPU’s inability to handle higher graphical loads.

At 2560x1440, the performance drops across all presets. Low settings average 76 FPS, which is playable but a significant step down from the 106 FPS at 1080p. Medium averages 62 FPS, with a minimum of 53 and a maximum of 71. High settings average 51 FPS, and Ultra falls to 32 FPS. The gap between Low and Ultra at this resolution is 44 FPS, showing that the GPU’s limits are being reached more quickly as resolution increases.

At 3840x2160, the results are largely below the playability threshold. Low settings average 47 FPS, which is the only preset above 40 FPS. Medium averages 39 FPS, with a minimum of 33 and a maximum of 44. High averages 32 FPS, and Ultra plummets to 20 FPS. The difference between Low and Ultra at 4K is 27 FPS, indicating that while the absolute numbers are low, the relative impact of settings is less pronounced than at lower resolutions, likely due to the GPU being completely saturated.

How This Combo Ranks

In the global ranking for Downfall, this combination of the AMD Ryzen 5 7500F and Intel Arc B390 places at position 2589 out of 2928 tested combos. This rank puts it in the bottom 12% of all systems tested for this game, confirming that it is a low-performance configuration for this title. The percentile ranking of the GPU itself is notable: the Arc B390 sits at the 9th percentile versus all GPUs, indicating that it outperforms only a small fraction of the graphics cards in the database.

The CPU, in contrast, is a much stronger component. The Ryzen 5 7500F has a percentile rank of 77 versus all CPUs, meaning it is better than three-quarters of processors tested. This disparity between the CPU’s high percentile and the GPU’s low percentile underscores that the graphics card is the weak link in this pairing. The combo’s overall rank in the game is dragged down by the GPU, as the CPU’s capabilities are not fully utilized due to the graphics bottleneck. The data suggests that this combo is suitable for low-resolution, low-settings gaming, but it will struggle in more demanding scenarios.

CPU Role

The AMD Ryzen 5 7500F is a 6-core, 12-thread processor from the 7000 series, based on the Zen 4 architecture. It has a base clock of 3.70 GHz and a boost clock of 5.00 GHz. In benchmark tests, it scores 974 in 3dMark single-thread, 3218 in Cinebench R23 single-core, and 22799 in Cinebench R23 multicore. These scores indicate a strong modern processor. Its average benchmark score of 24964 places it near rivals like the Intel Core i7-11850H (24935) and the AMD Ryzen 5 8400F (25005), with delta percentages of 0.1% and -0.2%, respectively.

In Downfall, the CPU’s role appears to be secondary. Given that the measured FPS drops consistently with resolution, the Ryzen 5 7500F is clearly not the bottleneck. Its high single-thread performance (3841 in PassMark single-thread) ensures that it can handle the game’s logic and physics without limiting the frame rate. The 32 MB of shared L3 cache and 83.2 GB/s memory bandwidth provide ample headroom for game data. The data shows that even at 1080p Low, where the CPU would be most likely to limit, the frame rate reaches 106 FPS, which is high enough to suggest the CPU is not stressed. The CPU’s performance is more than sufficient for this title, and the limiting factor is definitively the GPU.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, with a base clock of 300 MHz and a boost clock of 2500 MHz. It features 1536 shading units and 24 ROPs. Its performance is exceptionally low, as evidenced by its 3DMark Steel Nomad DX12 score of 1482, which places it in the 9th percentile of all GPUs. Its nearest rivals are older, low-end parts like the NVIDIA GeForce GT 520MX (1463), NVIDIA GeForce 800M (1460), and NVIDIA GeForce GT 625 OEM (1446), with delta percentages of 1.3%, 1.5%, and 2.5%, respectively.

The GPU’s memory is system-shared, meaning it relies on the system’s DDR5 RAM, with bandwidth being system-dependent. This architecture is a significant disadvantage for gaming. The measured FPS data in Downfall reflects this limitation. The GPU’s pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are low, which explains why higher resolutions and settings cause such dramatic FPS drops. The FP32 performance of 7.680 TFLOPS is also modest. The data shows that the Arc B390 is the primary bottleneck in this pairing. At 1080p Low, it manages 106 FPS, but any increase in resolution or settings severely impacts performance. This is consistent with a GPU that lacks the raw processing power and memory bandwidth to handle modern game loads, confirming that the GPU is the definitive limiting factor in this combo for Downfall.
