Downfall

The AMD Ryzen 7 5800XT paired with the Intel Arc B390 delivers a very restricted experience in Downfall, with playability largely confined to lower resolutions and settings. The recorded data shows this combo struggles to maintain smooth frame rates at higher demands, placing it near the bottom of the database rankings. The Arc B390, acting as an integrated graphics solution, is the primary limiting factor, making this pairing suitable only for modest gaming expectations.

Measured FPS Breakdown

The measured FPS data for this combo reveals a clear pattern of performance degradation as resolution and graphical load increase. At 1920x1080, the combination is capable of playable frame rates on several presets, but the margin shrinks quickly as you move up in resolution.

At 1920x1080, the Low preset delivers an average of 106 FPS, which is the highest recorded average for this pairing. The Medium preset drops to an average of 87 FPS, with a minimum of 74 FPS and a maximum of 100 FPS, indicating a stable experience with some headroom. High settings still remain above the 60 FPS threshold, achieving an average of 71 FPS. The Ultra preset, however, falls dramatically to an average of 44 FPS, which is below the playable threshold and shows the limits of the GPU.

Moving to 2560x1440, the performance hit is substantial. The Low preset averages 76 FPS, which remains playable, but the Medium preset just barely clears the threshold at 62 FPS, with a minimum of 53 FPS and a maximum of 71 FPS. This suggests occasional dips below 60 FPS during demanding scenes. High settings drop to an average of 51 FPS, which is not playable, and Ultra plummets to 32 FPS, making it entirely unsuitable.

At 3840x2160, the combo is not playable on any preset. The Low setting achieves an average of 47 FPS, which is still below the 60 FPS target. Medium averages 39 FPS, with a minimum of 33 FPS and a maximum of 44 FPS. High drops to 32 FPS, and Ultra is a slideshow at 20 FPS. The data shows that this resolution is simply beyond the capabilities of the Arc B390 in this game.

The pattern is consistent: the gap between Low and Ultra at each resolution is significant. At 1920x1080, the difference between Low and Ultra is 62 FPS. At 2560x1440, the difference is 44 FPS, and at 3840x2160, it is 27 FPS. This indicates that the GPU is heavily stressed by the higher presets, and the CPU has little room to compensate.

Similar Performance Alternatives

The database provides nearest rival comparisons for both the CPU and GPU, which helps contextualize where this combo sits. For the CPU, the AMD Ryzen 7 5800XT is closely matched by the AMD Ryzen 7 7840H, with a delta of 0%. This means that in synthetic benchmarks, these two processors perform essentially identically. The AMD Ryzen 5 9600X is 0.6% faster, while the AMD Ryzen 7 8845HS and AMD Ryzen 7 7840HS are both 0.3% slower. For gaming purposes, these differences are negligible, and any of these CPUs would produce the same frame rates when paired with the same GPU.

The GPU situation is more critical. The Intel Arc B390 is an integrated graphics processor, and its nearest rivals are all very old, low-end discrete GPUs. The NVIDIA GeForce GT 520MX is 1.3% faster, the NVIDIA GeForce 800M is 1.5% faster, the NVIDIA GeForce GT 625 OEM is 2.5% faster, and the NVIDIA GeForce GT 710 is 2.7% faster. These are all ancient parts from a decade ago, which highlights just how limited the Arc B390 is for gaming. The delta percentages are small, but they all point to the same conclusion: this GPU is near the bottom of the performance stack. A system with any of these rival GPUs would behave very similarly to this combo, struggling with the same resolutions and settings in Downfall.

The implications are clear. If you have a system with an AMD Ryzen 7 7840H or an AMD Ryzen 5 9600X, you would see the same frame rates in this game, because the GPU is the bottleneck. Similarly, if you swapped the Arc B390 for a GeForce GT 710, you would get nearly identical performance, with the GT 710 being slightly faster in synthetic tests. This combo is not about CPU power; it is entirely about the GPU's limitations.

CPU and GPU Roles

In this pairing, the GPU is overwhelmingly the dominant factor in determining Downfall's performance. The CPU, an AMD Ryzen 7 5800XT, is a high-end desktop processor with 8 cores and 16 threads, and its benchmark scores, such as a Cinebench R23 multicore score of 23794, are far beyond what this game requires. The data shows that the GPU is the bottleneck at every resolution and preset.

Evidence for this comes from the scaling between resolutions. When moving from 1920x1080 to 2560x1440 on Low settings, the average FPS drops from 106 to 76, a 28% reduction. Moving from 2560x1440 to 3840x2160 on Low settings, the average FPS drops from 76 to 47, a 38% reduction. This steep decline with increasing pixel count is a classic sign of a GPU-bound scenario. The CPU is not being stressed by these resolution changes; the GPU simply cannot render frames fast enough.

The same pattern holds for presets. At 1920x1080, going from Low to Medium reduces FPS from 106 to 87, and going from Medium to High reduces it from 87 to 71. Each step up in settings adds more shading and texture work, which directly impacts the GPU's throughput. The CPU's workload increases, but it has ample headroom. Its Passmark multithread score of 28053 indicates it can handle far more complex scenes than this game presents.

At 2560x1440, the GPU is even more strained. The jump from Low to Medium only yields a 14 FPS difference, from 76 to 62, showing that the GPU is already near its limits. The CPU, by contrast, is not the reason for this limitation. If the CPU were the bottleneck, we would see similar frame rates across different resolutions, which is not the case. The data consistently points to the Intel Arc B390 as the sole constraint, with the CPU essentially idle in comparison.

Best Settings per Resolution

Based on the recorded data, the best settings are defined as the most demanding preset that still maintains an average FPS at or above the 60 FPS playable threshold. The database's verdicts confirm the following recommendations.

At 1920x1080, the best playable preset is High, with an average of 71 FPS. This provides a good balance of visual fidelity and performance. The Low and Medium presets are also playable, but High offers better image quality without dropping below the threshold. The Ultra preset is not recommended, as it averages only 44 FPS.

At 2560x1440, the best playable preset is Medium, with an average of 62 FPS. This is a close call, as the minimum FPS is 53, meaning there will be moments where the frame rate dips below 60. Low is also playable at 76 FPS, but Medium offers superior visuals. High and Ultra are not playable at this resolution.

At 3840x2160, there is no best settings preset because no preset achieves a playable average FPS. The closest is Low at 47 FPS, but it falls short of the 60 FPS target. Users with this resolution should consider lowering the resolution or upgrading the GPU.

How This Combo Ranks

The combo of an AMD Ryzen 7 5800XT and an Intel Arc B390 ranks 3303 out of 3716 tested combinations in Downfall. This places it in the bottom 11% of all systems in the database, indicating very poor performance for this game. The ranking is heavily influenced by the GPU, which is an integrated part with a 3dmark Steel Nomad score of only 1482, placing it in the 9th percentile of all GPUs.

This low ranking is consistent with the measured FPS data. The combo cannot handle 3840x2160 at all, and only barely manages 2560x1440 on Medium settings. Even at 1920x1080, it falls short on Ultra. The CPU's high performance, with an 81st percentile ranking, does not compensate for the GPU's lack of power. In this game, the GPU is the determining factor, and its 9th percentile standing drags the entire combo down.

When compared to other tested combos, this system is clearly at the lower end. The 3716 total combinations include many with discrete graphics cards that perform far better. The ranking of 3303 suggests that a user would need to significantly lower their graphical expectations to play Downfall smoothly. The data shows that this combo is only suitable for 1920x1080 gaming on medium-to-high presets, and even then, it is not a high-performance experience. For anyone considering this pairing for Downfall, the database results are clear: expect a modest, low-detail gaming experience.
