Downfall

The AMD Ryzen 7 5800X3D paired with the Intel Arc B390 presents a distinct performance profile in Downfall. The data recorded for this combination shows a clear hierarchy across resolutions and presets, with the playable threshold set at 60 FPS in the database. Below is a detailed breakdown of the measured results.

Measured FPS Breakdown

At 3840x2160, the combination struggles to maintain fluid motion. The High preset yields an average of 32 FPS. Lowering to Medium produces an average of 39 FPS, with a recorded minimum of 33 FPS and a maximum of 44 FPS. The Low preset improves the average to 47 FPS. The Ultra preset is the most demanding, dropping the average to 20 FPS. None of these figures approach the 60 FPS playable threshold.

Moving to 2560x1440, the results improve substantially. The Low preset delivers an average of 76 FPS, which clears the playable threshold comfortably. The Medium preset achieves an average of 62 FPS, with a minimum of 53 FPS and a maximum of 71 FPS. This places Medium at the boundary of playability, averaging above 60 FPS but dipping below during intense scenes. The High preset averages 51 FPS, which falls short of the threshold. The Ultra preset averages 32 FPS, mirroring the 4K High result.

At 1920x1080, the combination performs best. The Low preset reaches an average of 106 FPS. The Medium preset averages 87 FPS, with a minimum of 74 FPS and a maximum of 100 FPS, keeping every recorded frame above the 60 FPS mark. The High preset averages 71 FPS, which also clears the threshold. The Ultra preset averages 44 FPS, remaining below the playable mark.

The data indicates that the gap between presets is consistent. For example, at 1920x1080, dropping from Medium to Low yields a 19 FPS improvement in the average. At 2560x1440, the same preset change yields a 14 FPS improvement. At 3840x2160, it yields an 8 FPS improvement. This pattern suggests that resolution scaling affects the cost of each preset level.

CPU and GPU Roles

The recorded data shows that the GPU becomes the limiting factor as resolution increases. At 1920x1080, the CPU has more headroom, allowing the GPU to deliver higher frame rates across all presets. The jump from 1920x1080 to 2560x1440 at the Low preset reduces the average FPS from 106 to 76, a drop of 30 FPS, or roughly 28%. At the Medium preset, the same resolution change reduces the average from 87 to 62, a drop of 25 FPS, or roughly 29%. This proportional scaling indicates that the GPU is the primary constraint at both resolutions.

At 3840x2160, the GPU is heavily stressed. The Low preset average of 47 FPS is less than half of the 1920x1080 Low average of 106 FPS. The High preset at 3840x2160 averages 32 FPS, which is 19 FPS lower than the same preset at 2560x1440. The Ultra preset at 3840x2160 averages 20 FPS, which is 12 FPS lower than the Ultra preset at 2560x1440. These reductions show that the GPU cannot keep up with the pixel count at 4K.

The CPU, an AMD Ryzen 7 5800X3D with 8 cores and 16 threads, has a 3Dmark single-thread score of 884 and a Cinebench R23 multicore score of 14317. It ranks in the 80th percentile among all CPUs in the database. However, the Intel Arc B390 GPU has a 3Dmark Steel Nomad DX12 score of 1482 and ranks in the 9th percentile among all GPUs. This percentile gap suggests that the GPU is the weaker link in this pairing. The CPU's performance headroom is not fully utilized at higher resolutions, as the GPU saturates first.

The scaling between presets at each resolution further clarifies the GPU's role. At 1920x1080, the difference between Low and Ultra is 62 FPS (106 to 44). At 2560x1440, the difference is 44 FPS (76 to 32). At 3840x2160, the difference is 27 FPS (47 to 20). As resolution increases, the absolute FPS loss from raising settings shrinks, indicating that the GPU is already operating near its limit. The CPU's role is more apparent at lower resolutions, where it can feed the GPU enough data to reach higher frame rates, but even then, the GPU's raw throughput caps the results.

How This Combo Ranks

In the database, this CPU and GPU combination ranks 3303 out of 3716 tested combos for Downfall. This places it in the lower portion of the ranking, specifically in the 11th percentile of all tested combinations. The rank reflects the GPU's limited capability relative to other available hardware. The CPU itself is strong, ranking in the 80th percentile of all CPUs, but the GPU's 9th percentile ranking drags the overall combo down.

The combination's rank suggests that most other tested setups achieve higher frame rates in Downfall. The GPU's nearest rivals include the NVIDIA GeForce GT 520MX, which has an average score of 1463 and a delta of 1.3%, the NVIDIA GeForce 800M with an average score of 1460 and a delta of 1.5%, the NVIDIA GeForce GT 625 OEM with an average score of 1446 and a delta of 2.5%, and the NVIDIA GeForce GT 710 with an average score of 1443 and a delta of 2.7%. These rivals all perform within 3% of the Arc B390's average score of 1482, indicating that this GPU sits at the very bottom of the performance spectrum.

The CPU's nearest rivals, by contrast, are much stronger. The AMD Ryzen 7 6800U has an average score of 27887 with a delta of 0%, the Intel Core i9-10900K has an average score of 27872 with a delta of 0.1%, the AMD Ryzen AI 5 PRO 340 has an average score of 27932 with a delta of -0.1%, and the Intel Core i5-12600KF has an average score of 27799 with a delta of 0.3%. The CPU's average benchmark score is 27896, which is nearly 19 times higher than the GPU's average score. This disparity is reflected in the combo's overall ranking, as the GPU's low performance limits the system's ability to render Downfall at high frame rates.

The Verdict

The database's verdict is clear: this PC cannot run Downfall at 3840x2160 with any preset that reaches the 60 FPS playable threshold. All four presets at 4K fall below 60 FPS, with the best result being Low at 47 FPS. The system is not playable at this resolution.

At 2560x1440, the system is playable on two presets. The Low preset averages 76 FPS, which clears the threshold. The Medium preset averages 62 FPS, which also clears the threshold on average, though the minimum of 53 FPS indicates occasional dips below 60 FPS. The High and Ultra presets at this resolution are not playable, averaging 51 FPS and 32 FPS respectively.

At 1920x1080, the system is playable on three presets. The Low preset averages 106 FPS, the Medium preset averages 87 FPS with a minimum of 74 FPS, and the High preset averages 71 FPS. All three maintain an average above 60 FPS. The Ultra preset at 1080p averages 44 FPS, which is not playable.

The verdict by resolution confirms this analysis. For 3840x2160, there are no playable settings, and the best settings field is null. For 2560x1440, the playable settings are Low and Medium, with Medium being the best at 62 FPS average. For 1920x1080, the playable settings are High, Low, and Medium, with High being the best at 71 FPS average. The system can run the game smoothly at 1080p with High settings, and at 1440p with Medium settings, but it cannot handle 4K at any preset.

Similar Performance Alternatives

For the CPU, the nearest rivals in the database are all close in average benchmark score. The AMD Ryzen 7 6800U scores 27887, which is 9 points lower than the 5800X3D's 27896, a delta of 0%. The Intel Core i9-10900K scores 27872, 24 points lower, a delta of 0.1%. The AMD Ryzen AI 5 PRO 340 scores 27932, 36 points higher, a delta of -0.1%.

Any of these CPUs would behave nearly identically in Downfall when paired with the same GPU, as the differences are within 0.3%.

For the GPU, the nearest rivals are all significantly weaker in benchmark terms. The NVIDIA GeForce GT 520MX scores 1463, which is 19 points lower than the Arc B390's 1482, a delta of 1.3%. The NVIDIA GeForce 800M scores 1460, 22 points lower, a delta of 1.5%. The NVIDIA GeForce GT 625 OEM scores 1446, 36 points lower, a delta of 2.5%. The NVIDIA GeForce GT 710 scores 1443, 39 points lower, a delta of 2.7%. These GPUs would produce frame rates very close to the Arc B390 in Downfall, likely within a few FPS of the recorded averages. However, all of them are slower, so swapping to any of these GPUs would not improve performance.

The CPU alternatives would maintain the same FPS results, as the GPU remains the bottleneck. The GPU alternatives would slightly reduce performance, but the differences are small enough that the playable resolutions and presets would remain the same. The 1080p High preset at 71 FPS would likely drop to around 69 or 70 FPS with the GT 520MX, still above 60 FPS. The 1440p Medium preset at 62 FPS might drop to 60 or 61 FPS, potentially becoming borderline.

Best Settings per Resolution

At 3840x2160, no preset achieves the 60 FPS threshold. The best average FPS is 47 at Low settings, but this still falls short. The database lists no best settings for this resolution, and the system should be considered unplayable at 4K.

At 2560x1440, the most demanding preset that stays at or above 60 FPS on average is Medium, which achieves 62 FPS. The minimum FPS at this setting is 53, so there will be occasional dips below the threshold, but the average is above it. Low also works at 76 FPS average, but Medium is the higher quality option.

At 1920x1080, the most demanding preset that stays at or above 60 FPS on average is High, which achieves 71 FPS. The Medium preset is also viable at 87 FPS average, and Low at 106 FPS, but High provides the best visual quality while maintaining an average above 60 FPS. The Ultra preset at 44 FPS is not recommended.

These settings represent the optimal balance between visual fidelity and frame rate based on the measured data. Users prioritizing a consistent 60 FPS minimum should consider dropping to the next lower preset, as the Medium preset at 1440p has a minimum of 53 FPS, and the High preset at 1080p has no recorded minimum, suggesting it may dip below the average.
