Downfall

The AMD Ryzen 5 9600X paired with the Intel Arc B390 delivers a playable but constrained experience in Downfall, a 2016 horror title. The combination of a modern six-core Zen 5 processor and a low-power integrated GPU from Intel’s Panther Lake generation produces frame rates that are heavily dependent on resolution and graphical settings. Benchmark results indicate that while the CPU is vastly overqualified for this task, the integrated GPU acts as the primary bottleneck, limiting performance even at 1080p.

Resolution Scaling

The performance drop from 1080p to 4K reveals a classic GPU-bound scenario. At the Low preset, the average frame rate falls from 106 FPS at 1920x1080 to 47 FPS at 3840x2160, a decline of roughly 56%. This steep reduction is typical when the rendering workload shifts almost entirely onto the graphics processor, and the Intel Arc B390, with its 7.680 TFLOPS of FP32 compute and system-shared memory, struggles to sustain high throughput at 4K.

The scaling becomes even more pronounced at higher quality settings. Moving from 1080p High (71 FPS) to 4K High (32 FPS) represents a 55% loss, while the Ultra preset collapses from 44 FPS at 1080p to just 20 FPS at 4K — a 55% drop that lands the experience well below the threshold of smooth gameplay. The Medium preset tells a similar story: 87 FPS at 1080p drops to 39 FPS at 4K, a 55% reduction. The consistency of this scaling pattern across all settings strongly suggests that the GPU is the limiting component; the resolution increase directly multiplies the pixel count, and the Arc B390’s fixed compute resources cannot keep pace.

At 1440p, the intermediate resolution, the same trend holds. Low preset averages 76 FPS, High delivers 51 FPS, and Ultra falls to 32 FPS. The 4K Ultra result of 20 FPS is the worst-case scenario, confirming that this combo is not suited for high-resolution, high-detail gaming in Downfall. The data shows that the system is most efficient at 1080p, where the GPU’s limitations are less exposed, and that any move to higher resolutions incurs a predictable and severe penalty.

CPU Role

The AMD Ryzen 5 9600X is a 6-core, 12-thread processor based on the Zen 5 architecture, built on a 4 nm process at TSMC. It operates at a base clock of 3.90 GHz and can boost up to 5.40 GHz, with 32 MB of shared L3 cache. In synthetic benchmarks, it scores 17528.5 in Cinebench R23 multi-core and 2183.5 in single-core, placing it in the 81st percentile among all CPUs. Its nearest rivals include the AMD Ryzen 7 PRO 5755GE (average score 29656, deltaPct +0.2) and the AMD Ryzen 7 7840H (average score 29868, deltaPct -0.5), indicating that the 9600X is a strong performer in its class.

For Downfall, a game released in 2016, the CPU is dramatically overprovisioned. The horror genre typically does not demand high thread counts, and the 9600X’s single-thread performance — evidenced by a Geekbench single-core score of 2923 and a Passmark single-thread score of 4570 — is more than sufficient to feed the Intel Arc B390. The CPU’s 12 threads and 89.6 GB/s of memory bandwidth via DDR5 are unlikely to be a bottleneck at any resolution tested. The benchmark results show that frame rates scale almost perfectly with resolution and settings, which is the hallmark of a GPU-bound system. The CPU’s role here is to ensure consistent frame pacing, and it does so without issue; the minimum FPS values recorded (33 FPS at 4K Medium, 53 FPS at 1440p Medium, 74 FPS at 1080p Medium) are all higher than the GPU would otherwise allow, suggesting the processor is never starved for data.

GPU Role

The Intel Arc B390 is an integrated GPU based on the Xe3-LPG architecture, built on a 3 nm process at Intel. It features 1536 shading units, 48 texture mapping units, and 24 ROPs, with 12 ray tracing cores. Its boost clock reaches 2500 MHz, and it delivers 7.680 TFLOPS of FP32 performance. The memory is system-shared, meaning bandwidth is dependent on the host platform’s DDR5 configuration. In the 3DMark Steel Nomad DX12 benchmark, the Arc B390 scores 1482, placing it in the 9th percentile among all GPUs. Its nearest rivals are the NVIDIA GeForce GT 520MX (score 1463, deltaPct +1.3) and the NVIDIA GeForce 800M (score 1460, deltaPct +1.5), which are legacy mobile parts from over a decade ago.

This context is critical for understanding Downfall performance. The Arc B390 is essentially competing with entry-level discrete GPUs from the early 2010s. At 1080p Low, it achieves 106 FPS, which is playable, but at 1080p Ultra, it drops to 44 FPS — a 58% reduction from Low. The Ultra preset likely enables additional graphical features such as higher-quality shadows, textures, and post-processing effects, which the GPU’s 24 ROPs and 48 TMUs cannot handle efficiently. The 4K Ultra result of 20 FPS is nearly unplayable, confirming that the GPU is the primary performance limiter. The system-shared memory also means that the GPU competes with the CPU for bandwidth, though the 89.6 GB/s of the Ryzen 5 9600X’s dual-channel DDR5 setup is generous for an integrated solution. The data shows that the Arc B390 is best suited for 1080p gaming at low-to-medium settings, and that it cannot sustain acceptable frame rates at higher resolutions or quality levels.

How This Combo Ranks

In the database of tested CPU and GPU combinations for Downfall, this pairing ranks 3303 out of 3716 total combos. This places it in the bottom 11% of all tested configurations, a position that reflects the GPU’s severe limitations. The Ryzen 5 9600X is a modern, high-performance CPU, but it is paired with an integrated GPU that is comparable to decade-old entry-level discrete graphics. The combo rank is a direct consequence of this imbalance: the CPU is capable of much higher frame rates, but the GPU holds performance back across all resolutions and settings.

The nearest rivals to the CPU alone — the AMD Ryzen 7 PRO 5755GE, Ryzen 7 7840H, Ryzen 7 5800XT, and Ryzen 7 8845HS — all have similar average benchmark scores, but when paired with a more capable GPU, they would likely achieve much higher ranks in Downfall. The Intel Arc B390’s nearest GPU rivals, such as the NVIDIA GeForce GT 520MX and GT 710, are similarly low-end, confirming that the GPU is the weak link. The 3303rd rank out of 3716 is a clear signal that this combo is not recommended for gaming at higher settings or resolutions, and that any upgrade to the GPU would yield substantial improvements.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best performance. The Low preset averages 106 FPS, providing a smooth experience for a horror title where responsiveness matters. Medium drops to 87 FPS, with a minimum of 74 FPS and a maximum of 100 FPS, still comfortably playable. High averages 71 FPS, which is acceptable but begins to show the GPU’s strain. Ultra falls to 44 FPS, which is below the 60 FPS threshold and may feel sluggish during intense scenes.

At 2560x1440, the frame rates decline further. Low averages 76 FPS, still playable for most users. Medium drops to 62 FPS, with a minimum of 53 FPS and a maximum of 71 FPS, which is borderline but manageable. High averages 51 FPS, which is below the ideal smoothness target. Ultra falls to 32 FPS, making it difficult to play without significant stutter.

At 3840x2160, the results are largely unplayable. Low averages 47 FPS, which is marginal. Medium averages 39 FPS, with a minimum of 33 FPS and a maximum of 44 FPS, all below acceptable thresholds. High averages 32 FPS, and Ultra averages just 20 FPS. None of the 4K presets deliver a consistent 60 FPS experience, and the Low preset is the only one that approaches playability, albeit with noticeable compromises.

Settings Recommendations

For the best balance of visual quality and performance, the Medium preset at 1920x1080 is the optimal choice. It delivers an average of 87 FPS with a minimum of 74 FPS, ensuring smooth gameplay during both exploration and scripted sequences. The 100 FPS maximum also indicates that the system has headroom for occasional bursts of action. The Low preset at 1080p offers higher frame rates (106 FPS average), but the visual downgrade may be unnecessary given that Medium already provides a solid experience.

At 1440p, the Medium preset is again the best compromise, averaging 62 FPS with a minimum of 53 FPS. This is playable, though users sensitive to frame drops may prefer the Low preset at 76 FPS for a more consistent experience. The High preset at 1440p (51 FPS) is borderline, and Ultra is not recommended.

At 4K, no preset delivers a truly smooth experience. The Low preset at 47 FPS is the least bad option, but it still falls short of 60 FPS. Users with 4K displays should strongly consider lowering the resolution to 1440p or 1080p for acceptable performance. The Ultra preset at 4K (20 FPS) is effectively unplayable and should be avoided. Given the GPU’s limitations, sticking to 1080p Medium or 1080p Low will provide the most consistent and enjoyable experience in Downfall.
