# Downfall with AMD Ryzen 7 9850X3D + Intel Arc B390

The AMD Ryzen 7 9850X3D paired with the Intel Arc B390 produces a highly unbalanced system for Downfall, a 2016 horror title that clearly favors CPU throughput over GPU muscle. The data shows this combo ranks 3303rd out of 3716 tested combinations, placing it in the bottom 11% of all tested configurations. The Arc B390's integrated graphics solution, with a 3DMark Steel Nomad DX12 score of just 1482 and a 9th percentile ranking among all GPUs, becomes the primary bottleneck at every resolution. Meanwhile, the Ryzen 7 9850X3D sits in the 92nd percentile of all CPUs, with an average benchmark score of 58386. The result is a system where the processor has ample headroom but the graphics solution consistently limits frame rates, especially at higher settings and resolutions.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 9850X3D is a Zen 5 architecture processor built on TSMC's 4 nm process, codenamed Granite Ridge. It features 8 cores and 16 threads, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. The CPU's cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a substantial 96 MB of shared L3 cache. This large cache configuration is particularly relevant for gaming workloads, as Downfall's horror environments often feature complex scene geometry and AI routines that benefit from fast data access. The processor supports DDR5 memory through a dual-channel interface with 89.6 GB/s of bandwidth, and it includes ECC memory support. With a TDP of 120 W, the 9850X3D is a high-power desktop part that fits the AMD Socket AM5 platform.

Benchmark data reveals the CPU's strong multi-threaded performance. In Cinebench R23, the 9850X3D scores 22807 points in multi-core and 2228 points in single-core tests. The PassMark multi-thread score is 41318, with a single-thread score of 4704. The processor's nearest rivals in overall average benchmark score include the Intel Xeon Platinum 8260M (58323, 0.1% slower), the Intel Xeon w5-2545 (58504, 0.2% faster), the Intel Core i9-14900 (58115, 0.5% slower), and the AMD Ryzen AI 9 HX 470 (58826, 0.7% faster). These tight margins, all within 0.7% of the 9850X3D's 58386 average, indicate that the CPU is competitively positioned among high-end desktop and workstation processors.

In Downfall specifically, the CPU's role is substantial but not limiting. At 1920x1080 with Low settings, the combo achieves 106 FPS average, which is the highest measured frame rate across all configurations. This suggests the CPU can drive high frame rates when the GPU is not the bottleneck. However, the gap between Low and Ultra settings at the same resolution is dramatic: 106 FPS versus 44 FPS, a difference that points to GPU limitations rather than CPU constraints. The 9850X3D's high single-thread performance, evidenced by its 343 Cinebench R15 single-core score and 2228 Cinebench R23 single-core score, should be more than sufficient for a 2016 title like Downfall. The processor's 4.70 GHz base clock and 5.60 GHz boost clock provide strong per-core performance that older games typically leverage effectively.

The CPU's 16 threads and 8 cores also handle background tasks and game logic without contention. PassMark physics score of 4171 and data compression score of 474501 indicate robust general-purpose performance. For a horror game that likely involves scripted sequences, physics interactions, and AI-driven enemy behavior, the 9850X3D delivers far more compute capability than Downfall requires. The data shows that even at 4K Ultra, where the average FPS drops to 20, the CPU is not the limiting factor — the GPU is. The measured FPS progression across resolutions and settings consistently follows GPU-bound behavior, with the CPU maintaining enough headroom to avoid introducing additional frame time variance.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, built on Intel's 3 nm process. It features a base clock of 300 MHz and a boost clock of 2500 MHz, with 1536 shading units, 48 texture mapping units, and 24 raster output units. The GPU includes 12 ray tracing cores and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Critically, the Arc B390 uses system shared memory for both VRAM and memory bandwidth, meaning its performance is highly dependent on the host system's RAM configuration. The pixel rate is 60.00 GPixel/s, and the texture rate is 120.0 GTexel/s, with FP32 performance of 7.680 TFLOPS.

The Arc B390's benchmark results are modest. Its 3DMark Steel Nomad DX12 score is 1482, placing it in the 9th percentile of all GPUs. Its nearest rivals are all older NVIDIA parts: the GeForce GT 520MX (1463, 1.3% slower), the GeForce 800M (1460, 1.5% slower), the GeForce GT 625 OEM (1446, 2.5% slower), and the GeForce GT 710 (1443, 2.7% slower). This places the Arc B390 in the same performance tier as entry-level discrete GPUs from over a decade ago, which is a poor match for a system built around a flagship 9850X3D processor. The GPU's integrated nature, with a 80 W TDP and no dedicated memory, means it shares system resources and cannot deliver the consistent frame pacing that discrete graphics solutions provide.

In Downfall, the GPU's limitations are evident across all measured configurations. At 1920x1080, the combo achieves 106 FPS on Low, 87 FPS on Medium, 71 FPS on High, and 44 FPS on Ultra. At 2560x1440, these figures drop to 76 FPS on Low, 62 FPS on Medium, 51 FPS on High, and 32 FPS on Ultra. At 3840x2160, the performance falls further: 47 FPS on Low, 39 FPS on Medium, 32 FPS on High, and 20 FPS on Ultra. The scaling pattern shows that the GPU becomes progressively more stressed as resolution increases, with the 4K Ultra result of 20 FPS being effectively unplayable. The system shared memory architecture means that the Arc B390's effective bandwidth is "System Dependent," which likely contributes to the steep performance drops at higher resolutions where memory bandwidth demands increase significantly.

The GPU's boost clock of 2500 MHz provides some headroom for lighter workloads, but the 300 MHz base clock indicates that power management can significantly throttle performance under sustained load. For a horror game like Downfall, which likely features dark environments and atmospheric effects that can be fill-rate intensive, the Arc B390's 24 ROPs and 60.00 GPixel/s pixel rate are insufficient for smooth gameplay at high settings. The 12 RT cores are present but likely underutilized in a 2016 title that predates widespread ray tracing adoption. The GPU's DirectX 12 Ultimate support is forward-looking but does not compensate for the fundamental lack of dedicated VRAM and bandwidth.

Settings Recommendations

The measured data provides clear guidance for optimizing the Downfall experience with this combo. At 1920x1080, Medium settings deliver 87 FPS average with a minimum of 74 FPS and maximum of 100 FPS. This is the sweet spot: it maintains frame rates comfortably above 60 FPS while offering better visual quality than Low settings. High settings at 1080p produce 71 FPS average, which is still playable but leaves less headroom for demanding scenes. Ultra settings at 1080p drop to 44 FPS, which is below the smoothness threshold most players prefer for a horror game where reaction time matters.

At 2560x1440, the picture changes. Low settings achieve 76 FPS average, Medium produces 62 FPS with a minimum of 53 FPS and maximum of 71 FPS, and High drops to 51 FPS. For 1440p gaming, Medium settings are the highest acceptable option, but the 53 FPS minimum may cause noticeable stutter in intense sequences. Low settings at 1440p provide a safer experience with 76 FPS average. High settings at 1440p at 51 FPS are borderline, and Ultra at 32 FPS is not recommended.

At 3840x2160, none of the settings achieve ideal playability. Low settings produce 47 FPS, Medium yields 39 FPS with a minimum of 33 FPS, High drops to 32 FPS, and Ultra falls to 20 FPS. For 4K, the combo is only viable at Low settings, and even then, the sub-60 FPS average may not satisfy players accustomed to smoother performance. The data suggests that 1080p Medium is the best overall experience, balancing visual fidelity with frame rate stability. For players who prioritize smoothness over visuals, 1080p Low at 106 FPS is the fastest configuration measured. The 44 FPS Ultra result at 1080p indicates that the Arc B390 cannot handle the highest preset even at the lowest resolution, so Medium or High presets are the practical ceiling.

How This Combo Ranks

The AMD Ryzen 7 9850X3D + Intel Arc B390 combination ranks 3303rd out of 3716 tested combos in Downfall, placing it in the 11th percentile of all systems. This ranking reflects the severe imbalance between the components: the CPU is a top-tier desktop processor, while the GPU is an integrated solution that performs similarly to decade-old entry-level discrete cards. The CPU's 92nd percentile ranking among all processors contrasts starkly with the GPU's 9th percentile ranking, creating a system where the graphics solution drags down overall gaming performance.

In the context of Downfall's tested combos, this pairing sits near the bottom, with only 413 configurations performing worse. The ranking is consistent across all resolutions and settings, with the GPU bottleneck preventing the CPU from demonstrating its full potential. For comparison, the CPU's nearest rivals in average benchmark score — the Intel Xeon Platinum 8260M, Intel Xeon w5-2545, Intel Core i9-14900, and AMD Ryzen AI 9 HX 470 — are all within 0.7% of the 9850X3D's score. However, the GPU's nearest rivals are all significantly weaker than the Arc B390's already modest performance, with the GeForce GT 710 being just 2.7% slower in 3DMark Steel Nomad. This combination of a top-tier CPU with a bottom-tier GPU results in a system that is poorly suited for Downfall, particularly at higher resolutions and settings where the GPU's limitations become most apparent.

The 3303rd ranking out of 3716 combos indicates that most other tested systems deliver better Downfall performance, even those with less capable CPUs but more capable GPUs. This underscores the importance of balanced component selection for gaming. While the CPU provides excellent compute performance for productivity tasks — as evidenced by its 22807 Cinebench R23 multi-core score and 41318 PassMark multi-thread score — these strengths do not translate into gaming performance when paired with an integrated GPU. Players using this combo for Downfall should expect performance similar to entry-level laptops from previous generations, rather than the high-end desktop experience that the CPU alone might suggest.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings presets, providing a comprehensive view of this combo's performance in Downfall.

At 1920x1080, the combo delivers its best results. Low settings achieve 106 FPS average, which is the highest measured frame rate for any configuration. Medium settings produce 87 FPS average with a minimum of 74 FPS and maximum of 100 FPS, indicating a stable experience with limited frame time variance. High settings drop to 71 FPS average, still playable but with less headroom. Ultra settings fall to 44 FPS average, which is below the 60 FPS threshold that most players consider smooth. The progression from Low to Ultra shows a 58.5% reduction in frame rate, reflecting the GPU's inability to handle increasingly demanding visual effects.

At 2560x1440, performance degrades noticeably. Low settings achieve 76 FPS average, which is a 28.3% drop from the 1080p Low result. Medium settings produce 62 FPS average with a minimum of 53 FPS and maximum of 71 FPS, with the minimum falling below 60 FPS. High settings yield 51 FPS average, and Ultra settings drop to 32 FPS. The 1440p data shows that Medium settings are the highest playable option, though the 53 FPS minimum may cause occasional stutter. Low settings provide a safer margin with 76 FPS average, though still below the 1080p Low performance.

At 3840x2160, the combo struggles across all settings. Low settings achieve 47 FPS average, which is a 38.2% drop from the 1440p Low result and a 55.7% drop from 1080p Low. Medium settings produce 39 FPS average with a minimum of 33 FPS and maximum of 44 FPS, indicating significant frame rate volatility. High settings drop to 32 FPS average, and Ultra settings fall to 20 FPS average. The 4K results are uniformly below playable thresholds, with even the best case (Low at 47 FPS) failing to maintain 60 FPS. The scaling from 1080p Low to 4K Low shows a 55.7% performance reduction, highlighting the GPU's limited fill rate and memory bandwidth constraints at higher resolutions. The minimum FPS data available only for Medium settings across all resolutions shows a consistent pattern: at 1080p the minimum is 74 FPS, at 1440p it is 53 FPS, and at 4K it is 33 FPS, representing a 55.4% reduction from 1080p to 4K. This data confirms that the Arc B390's system shared memory architecture cannot sustain consistent frame delivery as resolution increases, making 1080p Medium the only configuration that maintains a minimum above 60 FPS.
