Downfall

The AMD Ryzen 7 9850X3D and Intel Arc B390 combination presents an unusual pairing: a top-tier 2026 processor with a low-end integrated-class GPU. The data shows this system is heavily constrained by graphics performance in Downfall, a 2016 horror title. While the CPU ranks in the 92nd percentile among all processors, the GPU sits in the 9th percentile, creating a bottleneck that defines the entire experience.

Similar Performance Alternatives

For the processor, the AMD Ryzen 7 9850X3D sits in a tight cluster of high-end workstation and desktop chips. Its average benchmark score of 58,386 places it within a fraction of a percent of several alternatives. The Intel Xeon Platinum 8260M scores 58,323, a mere 0.1% difference. The Intel Xeon w5-2545 achieves 58,504, which is 0.2% ahead of the Ryzen. The Intel Core i9-14900 scores 58,115, trailing by 0.5%, while the AMD Ryzen AI 9 HX 470 leads the group at 58,826, a 0.7% margin. In practical terms, any of these chips would deliver nearly identical CPU-bound performance in Downfall, meaning the choice between them would not change the frame rates recorded in this database.

The graphics side tells a different story. The Intel Arc B390 has an average 3DMark Steel Nomad DX12 score of 1,482, which is remarkably close to several legacy NVIDIA parts. The GeForce GT 520MX scores 1,463, just 1.3% behind. The GeForce 800M trails by 1.5% with a score of 1,460. The GeForce GT 625 OEM sits 2.5% lower at 1,446, and the GeForce GT 710 is 2.7% behind at 1,443. These deltas are small enough that users upgrading from any of these older GPUs to the Arc B390 would see almost no measurable difference in Downfall performance. The recorded data indicates the Arc B390 behaves like a legacy entry-level graphics solution, not a modern discrete card.

CPU and GPU Roles

The benchmark results make the division of labor clear. At 1920x1080 with Low settings, the system produces 106 FPS average, which is the highest recorded result across all configurations. This suggests the CPU has ample headroom to feed the GPU even at this resolution. The Ryzen 7 9850X3D’s 8 cores and 16 threads, with a boost clock of 5.60 GHz, are far more than Downfall requires, as the game launched in 2016 and the processor’s benchmark scores reflect a modern high-end part.

However, the GPU becomes the limiting factor as resolution and settings increase. At 3840x2160 Ultra, the average FPS drops to 20, a reduction of 81% compared to the 1080p Low result. Even at 1440p High, the system only achieves 51 FPS, which falls below the 60 FPS playable threshold. The scaling pattern shows that resolution increases hurt performance far more than settings changes. Moving from 1080p Low to 1440p Low reduces the average from 106 to 76 FPS, a 28% drop. Moving from 1440p Low to 4K Low reduces the average from 76 to 47 FPS, a 38% drop. This indicates the Arc B390’s memory bandwidth, listed as system dependent, and its 7.680 TFLOPS of FP32 compute are simply insufficient for higher pixel counts.

The CPU’s role is mostly passive in this pairing. Since the GPU is the bottleneck at every resolution above 1080p Low, the Ryzen 7 9850X3D’s advantages in single-threaded and multi-threaded workloads do not translate into higher frame rates. The recorded data shows that even at 1080p High, where the CPU could theoretically matter more, the average FPS of 71 is likely GPU-limited given the same GPU produces 106 FPS at Low settings with the same resolution.

How This Combo Ranks

The combination ranks 3,303rd out of 3,716 tested configurations in Downfall. This places it in the bottom 11% of all tested combos, which is consistent with the GPU’s low percentile ranking. The processor’s 92nd percentile standing does little to lift the overall ranking because the graphics adapter is the decisive component in this game. The rank reflects the measured FPS data, not component benchmarks, so the system’s poor performance at 4K and limited playability at 1440p drag the overall position down.

Compared to other combos in the database, this pairing behaves like a system with a weak integrated GPU, despite the Arc B390 being marketed as a discrete part. The 3DMark score of 1,482 and the 9th percentile GPU ranking confirm that this is not a typo or a misconfiguration. The rank of 3,303 out of 3,716 means there are only 413 tested combinations that perform worse in Downfall, which is a very small margin of safety for a game that is nearly a decade old.

The Verdict

This PC can run Downfall, but only under specific conditions. The verdict data shows no playable settings at 3840x2160, meaning 4K is entirely out of reach. At 2560x1440, the system clears the 60 FPS threshold on Low and Medium settings, with Medium providing the best experience at 62 FPS average. At 1920x1080, the system is playable on High, Low, and Medium settings, with High being the best option at 71 FPS average.

The best overall configuration in the database is 1080p High, which delivers 71 FPS average with no recorded dips below the minimum frame rate. The 1440p Medium setting is the second-best option, averaging 62 FPS with a recorded range of 53 to 71 FPS. For users who prioritize smoothness over visual fidelity, 1080p Low at 106 FPS is the most responsive choice. The system cannot maintain 60 FPS at 4K under any settings, and Ultra presets are not playable at any resolution in the database.

Measured FPS Breakdown

At 1920x1080, the system produces its strongest results. Low settings average 106 FPS. Medium settings average 87 FPS, with a minimum of 74 and a maximum of 100. High settings average 71 FPS. Ultra settings drop to 44 FPS, which is below the 60 FPS threshold.

At 2560x1440, performance declines noticeably. Low settings average 76 FPS. Medium settings average 62 FPS, with a minimum of 53 and a maximum of 71. High settings average 51 FPS. Ultra settings fall to 32 FPS.

At 3840x2160, the system struggles across the board. Low settings average 47 FPS. Medium settings average 39 FPS, with a minimum of 33 and a maximum of 44. High settings average 32 FPS. Ultra settings produce only 20 FPS.

The data shows a clear pattern: settings changes from Low to Medium cost roughly 15-20% performance, while resolution changes from 1080p to 1440p cost roughly 25-30% performance. The jump from 1440p to 4K is even more punishing, costing 35-40% performance at equivalent settings. This is consistent with a GPU that has limited fill rate and memory bandwidth.

FAQ

Q: Can this system run Downfall at 60 FPS in 4K?

A: No. The measured data shows no playable settings at 3840x2160. The highest average FPS at 4K is 47 on Low settings, and every other preset falls below 40 FPS.

Q: What is the best setting for 1440p gaming?

A: Medium is the best playable setting at 2560x1440, averaging 62 FPS. Low settings also clear 60 FPS at 76 FPS average, but Medium provides higher visual quality while staying above the threshold.

Q: How does the Intel Arc B390 compare to its nearest rivals?

A: The Arc B390’s 3DMark Steel Nomad score of 1,482 is within 1.3% of the GeForce GT 520MX, within 1.5% of the GeForce 800M, within 2.5% of the GeForce GT 625 OEM, and within 2.7% of the GeForce GT 710. These are all legacy entry-level parts.

Q: Is the CPU or GPU the limiting factor in this game?

A: The GPU is the limiting factor at every resolution and preset combination. The CPU ranks in the 92nd percentile among all processors, while the GPU ranks in the 9th percentile. The FPS scaling with resolution changes confirms the graphics adapter is the bottleneck.

Q: What is the highest FPS this system can achieve in Downfall?

A: The highest recorded average FPS is 106, achieved at 1920x1080 with Low settings. This is the only configuration in the database that exceeds 100 FPS.

Q: Which resolution offers the best balance of quality and performance?

A: The database shows 1920x1080 High at 71 FPS average is the best balance. It delivers a stable frame rate above 60 FPS while providing higher visual fidelity than Low or Medium presets. The 1440p Medium option at 62 FPS is also viable but offers less headroom above the threshold.
