Downfall

How This Combo Ranks

The AMD Ryzen 7 7800X3D paired with the Intel Arc B390 ranks 3303 out of 3716 tested combinations in Downfall. This places the combo in the lower portion of the database, roughly in the 11th percentile of all tested systems. The ranking reflects a substantial mismatch between the two components: the CPU is a high-end desktop processor, while the GPU sits near the bottom of the performance distribution for this title.

The recorded data indicates this pairing is heavily constrained by the graphics subsystem. The Intel Arc B390 holds a percentile rank of 9 among all GPUs in the database, meaning roughly 91% of tested graphics cards deliver higher average benchmark scores. In contrast, the AMD Ryzen 7 7800X3D holds a percentile rank of 83 among all CPUs, placing it well above the median processor. The combination of a top-tier CPU with a low-tier GPU produces a system whose overall gaming performance in Downfall is limited almost entirely by the graphics card.

The combo rank of 3303 out of 3716 means only 413 tested combinations performed worse in this game. That is a weak result for a system built around the Ryzen 7 7800X3D, a processor that otherwise excels in multithreaded workloads. The CPU's average benchmark score of 33079 across all tests is strong, but that capability does not translate into high frame rates in Downfall because the GPU cannot keep pace.

CPU and GPU Roles

The Intel Arc B390 is the dominant performance limiter across all resolutions and presets. The GPU's 3DMark Steel Nomad DX12 score of 1482 is extremely low, and its nearest rivals in the database include the NVIDIA GeForce GT 520MX, the NVIDIA GeForce 800M, the NVIDIA GeForce GT 625 OEM, and the NVIDIA GeForce GT 710. All of these are entry-level or legacy parts, and the Arc B390's scores sit within 1.3% to 2.7% of them. This context makes it clear that no amount of CPU headroom can overcome the GPU's fundamental throughput ceiling.

The scaling between resolutions confirms the GPU-bound nature of this system. At 1080p Low, the combo averages 106 FPS. At 1440p Low, that drops to 76 FPS, a reduction of roughly 28%. At 4K Low, the average falls to 47 FPS, another drop of roughly 38% from 1440p. This steep decline with increasing pixel count is characteristic of a GPU-limited system: the CPU has ample spare capacity, but the graphics hardware cannot maintain frame rates as the rendering load grows.

Preset scaling tells the same story. At 1080p, moving from Low to Medium reduces the average from 106 to 87 FPS, and from Medium to High it falls to 71 FPS. The jump from High to Ultra cuts the average to 44 FPS, a dramatic collapse. At 1440p, the Low to Medium transition goes from 76 to 62 FPS, and High sits at 51 FPS with Ultra at 32 FPS. At 4K, even Low only reaches 47 FPS, and Ultra falls to 20 FPS. Each step up in graphical fidelity places additional strain on the GPU, and the Arc B390 simply lacks the raw shading throughput, texture rate, and pixel rate to handle these loads smoothly.

The CPU's role in this game is secondary. The Ryzen 7 7800X3D offers 8 cores, 16 threads, a boost clock of 5.00 GHz, and 96 MB of shared L3 cache. Benchmarks such as Cinebench R23 multicore at 16817 and Geekbench multicore at 15610 show strong computational performance. However, Downfall's frame rates at every resolution and preset are far below what the CPU alone could support. The data shows no scenario where the processor becomes the bottleneck; even at 4K Ultra with 20 FPS average, the limiting factor remains the GPU.

Similar Performance Alternatives

The GPU's nearest rivals in the database provide a useful reference for what other hardware would behave similarly. The NVIDIA GeForce GT 520MX scores 1463, which is 1.3% lower than the Arc B390's 1482. The NVIDIA GeForce 800M scores 1460, 1.5% lower. The NVIDIA GeForce GT 625 OEM scores 1446, 2.5% lower, and the NVIDIA GeForce GT 710 scores 1443, 2.7% lower. These four GPUs bracket the Arc B390's performance closely, meaning any of them would produce nearly identical frame rates in Downfall when paired with the same CPU. None of these alternatives would change the fundamental conclusion that the graphics card is the limiting factor.

On the CPU side, the Ryzen 7 7800X3D's nearest rivals are the AMD Ryzen 7 8700G, the Intel Core i7-13650HX, and the AMD Ryzen 7 7745HX, each with an average score of 33089 to 33091, essentially identical to the 7800X3D's 33079. The AMD Ryzen 9 PRO 6950H scores 33201, which is 0.4% higher. Swapping the 7800X3D for any of these processors would not meaningfully change Downfall's performance, since the system remains GPU-bound in every measured configuration.

The data suggests that a user who already owns a Ryzen 7 7800X3D and is considering a GPU upgrade would see far larger gains in Downfall than any CPU change. Likewise, a user with an Arc B390 would need a substantially stronger GPU to reach playable frame rates at higher resolutions or presets.

Measured FPS Breakdown

At 1920x1080, the recorded averages are as follows: Low produces 106 FPS, Medium produces 87 FPS with a minimum of 74 and a maximum of 100, High produces 71 FPS, and Ultra produces 44 FPS. The Medium preset is the only one at this resolution with complete min and max data, showing a spread of 26 FPS between the lowest and highest recorded frames.

At 2560x1440, Low averages 76 FPS, Medium averages 62 FPS with a minimum of 53 and a maximum of 71, High averages 51 FPS, and Ultra averages 32 FPS. The Medium preset again provides the only full min and max range, with an 18 FPS spread.

At 3840x2160, Low averages 47 FPS, Medium averages 39 FPS with a minimum of 33 and a maximum of 44, High averages 32 FPS, and Ultra averages 20 FPS. The Medium preset has an 11 FPS spread between minimum and maximum.

The pattern across all resolutions is consistent: each increase in preset level reduces the average frame rate substantially, and the gap between Low and Ultra grows as resolution increases. At 1080p, the difference between Low and Ultra is 62 FPS. At 1440p, it is 44 FPS. At 4K, it is 27 FPS. This compression at higher resolutions reflects the GPU reaching its absolute limits, where even the lowest settings cannot overcome the pixel throughput bottleneck.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is High, with an average of 71 FPS. Medium also clears the threshold at 87 FPS, and Low at 106 FPS, but High provides the highest visual quality among playable options. Ultra falls to 44 FPS and is therefore not recommended.

At 2560x1440, the best playable setting is Medium, averaging 62 FPS. Low averages 76 FPS and is also playable, but Medium offers better visual fidelity while still clearing the 60 FPS bar. High drops to 51 FPS and Ultra to 32 FPS, both below the threshold.

At 3840x2160, there is no preset that reaches 60 FPS. The closest is Low at 47 FPS, followed by Medium at 39 FPS, High at 32 FPS, and Ultra at 20 FPS. The database records no playable settings at this resolution.

The Verdict

The AMD Ryzen 7 7800X3D and Intel Arc B390 can run Downfall, but only under specific conditions. At 1920x1080, the system is playable on Low, Medium, and High settings, with High being the best visual option at 71 FPS average. At 2560x1440, the system is playable on Low and Medium, with Medium the best choice at 62 FPS average. At 3840x2160, the system is not playable on any preset, as even Low only reaches 47 FPS.

The CPU is more than capable of handling this game, and its 83rd percentile ranking among all processors means it will not be the limiting factor in any scenario. The GPU, however, ranks in the 9th percentile and is the clear bottleneck. Anyone seeking higher frame rates at 1440p or any playable performance at 4K would need a substantially more powerful graphics card. For 1080p gaming at medium-to-high settings, this combo delivers acceptable results, but the overall ranking of 3303 out of 3716 combos reflects a system whose potential is capped by its weakest component.
