Downfall

The AMD Ryzen 7 9800X3D paired with the Intel Arc B370 produces a very specific performance envelope in Downfall, one that is heavily dictated by the graphics solution. The data shows a system that can deliver smooth frame rates at lower resolutions and settings, but which quickly becomes constrained as graphical demands increase. This analysis breaks down the measured results across all resolutions and settings, providing a clear picture of what this combination offers.

Settings Recommendations

Choosing the right settings is critical for this particular combo, as the performance gap between presets is substantial. The measured data shows that the Arc B370's capabilities are the primary limiting factor. At 1920x1080, the Low preset yields an average of 96 FPS, which is the highest frame rate recorded for this system in any configuration. This is a playable and smooth experience for a horror title. The Medium preset at 1080p delivers 78 FPS, which is still very fluid and represents a significant visual upgrade over Low. The High preset drops to 64 FPS, which remains acceptable, but the drop from Medium is noticeable.

The Ultra preset presents a clear problem. At 1080p, it produces an average of only 40 FPS, which is a substantial 38 FPS decrease from Medium. This trend becomes more severe at higher resolutions. For the best balance of visual quality and performance, the Medium preset is the recommended choice. It provides the highest average frame rate that remains above the 60 FPS threshold at 1080p, while offering better visual fidelity than the Low preset. The data indicates that the step up from Medium to High is not worth the performance cost, and Ultra should be avoided entirely. At 2560x1440, the Medium preset is the only one that maintains a playable average above 50 FPS, with a score of 56. At 3840x2160, no preset achieves a 60 FPS average; the Low preset is the most viable option at 43 FPS, though the Medium preset at 35 FPS may be preferable for those who prioritize visuals over frame rate smoothness.

CPU Role

The AMD Ryzen 7 9800X3D is a high-end desktop processor with 8 cores and 16 threads, based on the Zen 5 architecture. Its specifications are formidable, with a base clock of 4.70 GHz and a boost clock of 5.20 GHz. The processor also features a substantial 96 MB of shared L3 cache. In synthetic benchmarks, it demonstrates strong multi-threaded performance, scoring 23,230 in Cinebench R23 multi-core and 18,696 in Geekbench multi-core. Its single-thread performance is also robust, with a Geekbench single-core score of 2,964.

However, in the context of Downfall, the CPU's role appears to be secondary. The frame rates across all tested settings and resolutions are relatively low, suggesting the workload is not CPU-bound. For instance, at 1080p Low, the system achieves 96 FPS, but this is a modest result for a processor of this caliber. The data suggests that even at lower resolutions, the graphics card is the bottleneck. The CPU is likely capable of producing far higher frame rates, but the Arc B370 cannot keep up. This is supported by the fact that frame rates scale downward significantly as resolution increases, which is a classic sign of GPU limitation. The Ryzen 7 9800X3D's performance is more than adequate to feed the GPU; the limiting factor is the graphics processor's ability to render frames. The processor's high core count and clock speeds are simply not being fully utilized in this scenario.

GPU Role

The Intel Arc B370 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture. Its specifications reveal a product designed for efficiency rather than high-end gaming. It has a base clock of 300 MHz and a boost clock of 2400 MHz. Its memory configuration is "System Shared," meaning it relies on the system's main memory, with bandwidth that is "System Dependent." This is a critical detail, as it means performance is heavily influenced by the system's memory speed and architecture. The GPU's raw compute power is limited, with an FP32 performance of 6.144 TFLOPS. Its benchmark results are also telling; it scores 1,184 in the 3DMark Steel Nomad DX12 test, placing it in the 5th percentile of all GPUs.

The benchmark data makes it clear that the Arc B370 is the defining component in this system's performance. Its nearest rivals in synthetic benchmarks are older, much less powerful cards like the ATI Mobility Radeon HD 5570 and the AMD Radeon HD 7650M. This context explains the measured FPS. The GPU's limited shading units (1,280) and texture mapping units (40) are simply overwhelmed by the demands of Downfall at higher settings. The system shared memory architecture further compounds this issue, as it lacks the dedicated high-bandwidth memory of a discrete GPU. The performance degradation from Low to Ultra settings is steep, and the inability to maintain high frame rates at 1440p and 4K is a direct result of the GPU's constrained memory bandwidth and compute resources. The GPU is the clear and dominant bottleneck in this configuration.

How This Combo Ranks

In the database of tested combinations, this pairing of the AMD Ryzen 7 9800X3D and the Intel Arc B370 ranks 2,688th out of 2,928 total combos for Downfall. This places it in the bottom 8% of all tested systems, which is a very low ranking. This low rank is unsurprising given the GPU's performance percentile. The Arc B370 is in the 5th percentile of all GPUs, while the CPU is in the 87th percentile of all CPUs. This stark contrast highlights a severe performance imbalance.

The combo's rank is dragged down almost entirely by the GPU. While the Ryzen 7 9800X3D is a top-tier processor, its performance is not the limiting factor here. The data indicates that pairing a high-end CPU with a low-end GPU results in a system that performs like the low-end GPU. The measured FPS data confirms this, as the results are consistent with what one would expect from a GPU in the 5th percentile. The combo's rank is a direct consequence of the GPU's inability to translate the CPU's potential into actual frame rates. The 2,688th rank serves as a clear indicator that this is not a balanced pairing for gaming, and the system's overall performance is capped by its weakest link.

Measured FPS Breakdown

The following is a detailed breakdown of the measured average FPS for all tested resolution and setting combinations.

1920x1080

• Low: The average frame rate is 96 FPS. This is the highest performance point for the entire system.
• Medium: The average frame rate is 78 FPS, with a minimum of 67 FPS and a maximum of 90 FPS.
• High: The average frame rate is 64 FPS.
• Ultra: The average frame rate is 40 FPS. This is a significant drop from the High preset.

2560x1440

• Low: The average frame rate is 68 FPS.
• Medium: The average frame rate is 56 FPS, with a minimum of 48 FPS and a maximum of 64 FPS.
• High: The average frame rate is 46 FPS.
• Ultra: The average frame rate is 29 FPS.

3840x2160

• Low: The average frame rate is 43 FPS.
• Medium: The average frame rate is 35 FPS, with a minimum of 30 FPS and a maximum of 40 FPS.
• High: The average frame rate is 29 FPS.
• Ultra: The average frame rate is 18 FPS.

The data shows a consistent and predictable pattern: as resolution and settings increase, performance declines. The system is only capable of delivering a consistently smooth experience (above 60 FPS) at 1080p with Low or Medium settings. At 1440p, only the Low preset manages to stay above the 60 FPS mark. At 4K, the system struggles to maintain playable frame rates on any preset.

Resolution Scaling

The performance scaling from 1080p to 4K clearly illustrates the impact of the GPU's limitations. At the Low settings preset, the system achieves 96 FPS at 1080p. This drops to 68 FPS at 1440p, a decrease of 28 FPS. When moving to 4K, the frame rate falls to 43 FPS, which is a 53 FPS drop from the 1080p figure. This represents a 55% reduction in performance from 1080p to 4K.

This scaling pattern is indicative of a system that is heavily limited by GPU memory bandwidth and processing power. The Arc B370's "System Shared" memory architecture is a major factor here, as it must compete with the CPU for system memory bandwidth. As the resolution increases, the amount of data required to render each frame increases exponentially. The GPU is unable to handle this increased load, leading to a sharp decline in performance. The frame rate drop is not linear; it's a steep curve that flattens out at lower performance levels, showing that the GPU is completely saturated at 4K.

The data suggests that the CPU is not a limiting factor in this scaling. If the CPU were the bottleneck, the frame rates would remain more consistent across resolutions. Instead, the performance drops dramatically, confirming that the GPU is responsible for the system's overall performance ceiling. The scaling behavior is a textbook example of a GPU-bound scenario, where the graphics processor's capabilities are the sole determinant of the final frame rate. The Arc B370 is simply not equipped to handle the data throughput required for 4K rendering in Downfall, resulting in the low performance numbers observed.
