Downfall

Measured FPS Breakdown

The recorded data for Downfall with the AMD Ryzen 7 5700X3D and Intel Arc B390 shows a clear performance hierarchy across resolutions and presets. At 1920x1080, the combination delivers its strongest results. Low settings produce an average of 106 FPS, Medium settings average 87 FPS with minimums of 74 FPS and maximums of 100 FPS, and High settings average 71 FPS. Ultra settings drop significantly to an average of 44 FPS, which falls below the 60 FPS playable threshold.

Moving to 2560x1440, the averages decline across every preset. Low settings still manage 76 FPS on average, while Medium settings hit 62 FPS with a minimum of 53 FPS and a maximum of 71 FPS. High settings average 51 FPS, and Ultra settings fall to 32 FPS. The 1440p Medium result is the only preset at this resolution that clears the playable threshold, and it does so by a narrow margin of just 2 FPS above the 60 FPS mark.

At 3840x2160, the combination struggles across the board. Low settings average 47 FPS, Medium settings average 39 FPS with minimums of 33 FPS and maximums of 44 FPS, High settings average 32 FPS, and Ultra settings average 20 FPS. None of the 4K presets reach 60 FPS, and the best result at this resolution, Low settings at 47 FPS, is still 13 FPS short of the playable threshold.

The data indicates that the gap between Low and Ultra settings widens as resolution increases. At 1080p, the difference between Low and Ultra averages is 62 FPS, while at 1440p the difference is 44 FPS, and at 4K the difference is 27 FPS. This pattern suggests that higher resolutions compress the performance envelope, reducing the headroom available for quality enhancements.

CPU and GPU Roles

The benchmark results reveal which component limits performance in Downfall at each resolution. At 1920x1080, the GPU appears to be the primary constraint. The Arc B390's 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile of all GPUs, which is a very low standing. The CPU, by contrast, sits in the 77th percentile of all CPUs with an average benchmark score of 24709. This large disparity in relative standing suggests the GPU cannot keep pace with the CPU's output at lower resolutions, where the processor would otherwise be capable of feeding frames at higher rates.

At 2560x1440, the balance shifts slightly. The average FPS drops from 106 at 1080p Low to 76 at 1440p Low, a reduction of 30 FPS. This scaling is consistent with a GPU-bound scenario, where increasing pixel count directly reduces frame delivery. The CPU's 16 threads and 96 MB of shared L3 cache provide ample headroom for the game's horror genre workloads, which typically favor single-thread responsiveness over massive multi-thread scaling.

At 3840x2160, the GPU becomes overwhelmingly dominant in determining performance. The average FPS at 4K Low is 47, which is less than half the 1080p Low result. The Arc B390's memory bandwidth is listed as system dependent, and its memory size is system shared, meaning the GPU relies on the host system's memory rather than dedicated VRAM. This architecture likely contributes to the steep performance degradation at 4K, where memory bandwidth demands increase substantially.

The preset scaling also illuminates component roles. At 1080p, moving from Low to Ultra costs 62 FPS on average, a 58% reduction. At 4K, the same preset change costs 27 FPS, a 57% reduction. The proportional cost remains similar across resolutions, but the absolute headroom shrinks, reinforcing that the GPU's low percentile standing is the binding constraint throughout.

How This Combo Ranks

The AMD Ryzen 7 5700X3D and Intel Arc B390 combination ranks 3303 out of 3716 tested combos in the database for Downfall. This places the combo in the bottom portion of all tested configurations, roughly in the 11th percentile of system performance for this game. The ranking reflects the GPU's weak standing more than the CPU's capabilities.

The CPU alone would not be the limiting factor. Its percentile vs all CPUs is 77, and its nearest rivals include the AMD Ryzen 5 7600X3D with an average score of 24728, which is only 0.1% faster, and the Intel Core i5-12450HX with an average score of 24576, which is 0.5% slower. These close deltas indicate the 5700X3D is well within the expected performance band for a mid-range desktop processor.

The GPU tells a different story. Its percentile vs all GPUs is 9, and its nearest rivals are all low-end NVIDIA parts. The GeForce GT 520MX scores 1463, which is 1.3% lower, while the GeForce GT 625 OEM scores 1446, which is 2.5% lower. The Arc B390 outperforms these parts by small margins, but they are all clustered at the bottom of the GPU performance spectrum. In a game like Downfall, which is a horror title from 2016, the CPU would typically be sufficient, but the GPU's low score drags the overall combo rank down.

The combo rank of 3303 out of 3716 means that approximately 88% of tested combinations deliver better performance in Downfall. This is a decisive indicator that the system is not well balanced for this game, with the GPU creating a significant bottleneck.

Similar Performance Alternatives

For the CPU, the nearest rivals in the database provide a clear picture of comparable processing power. The AMD Ryzen 5 7600X3D has an average score of 24728, which is 0.1% higher than the 5700X3D's 24709. This means the 7600X3D would behave nearly identically in CPU-bound scenarios, and the two processors can be considered interchangeable for Downfall. The AMD Ryzen 9 5900HX scores 24822, 0.5% higher, while the Intel Core i5-12450HX scores 24576, 0.5% lower. The Intel Core i5-11600 scores 24563, 0.6% lower. All four rivals fall within a 1.1% performance band, so any of them paired with the same GPU would produce nearly identical frame rates in this game.

For the GPU, the alternatives are equally close but occupy a very low performance tier. 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 GPUs would all perform within a few percent of the Arc B390, meaning a user with any of these parts would see similar FPS results in Downfall. The tight clustering of scores, from 1443 to 1482, confirms that the Arc B390 is not offering any meaningful advantage over these older or lower-end parts.

A user considering a CPU swap would see minimal changes. Moving from the 5700X3D to the fastest rival, the 5900HX, would improve CPU scores by only 0.5%, which would not translate into measurable FPS gains in a GPU-bound game like Downfall. Conversely, a GPU swap to any of the listed rivals would produce results within 2.7% of the Arc B390, so none of these alternatives would rescue the system's overall performance.

The Verdict

The AMD Ryzen 7 5700X3D and Intel Arc B390 can run Downfall, but only under specific conditions. At 1920x1080, the system delivers playable performance on High, Low, and Medium presets, with High being the best playable setting at an average of 71 FPS. This is the strongest configuration for this combo, offering a comfortable margin above the 60 FPS threshold.

At 2560x1440, the system remains playable on Low and Medium presets, with Medium being the best choice at an average of 62 FPS. This is a slim margin of only 2 FPS above the threshold, so users should expect occasional dips below 60 FPS during intense scenes, as the recorded minimum at Medium is 53 FPS.

At 3840x2160, the system cannot reach 60 FPS on any preset. The best 4K result is Low settings at 47 FPS, which falls short of the playable threshold by a substantial margin. Users targeting 4K should look for a different GPU, as the Arc B390's 9th percentile standing among all GPUs makes it the clear bottleneck in this configuration.

The data shows a system where the CPU is more than adequate for the game, sitting in the 77th percentile of all processors, but the GPU is severely underpowered relative to the rest of the field. The overall combo rank of 3303 out of 3716 confirms that this pairing is not well suited for Downfall beyond 1080p Medium or High settings. For a horror game with modest requirements, the system is functional at 1080p, but the GPU's low performance ceiling limits the experience to lower resolutions and presets.
