Downfall

AMD Ryzen 5 5600GT paired with the Intel Arc B390 presents a highly constrained configuration for Downfall, a horror title from 2016. The measured data indicates that this combination operates at the lower end of the performance spectrum, with the GPU acting as the primary bottleneck across all tested resolutions and settings. The benchmark results show a system capable of playable frame rates only at the lowest settings and resolutions, with a steep performance cliff emerging as graphical demands increase.

Resolution Scaling

The data reveals a clear and pronounced drop in average frame rates as resolution scales from 1080p to 4K, indicating that the Intel Arc B390 is the limiting component in this pairing. At 1080p High settings, the system produces 71 FPS, but this falls to 51 FPS at 1440p and further to 32 FPS at 4K. This represents a 55% reduction in performance from 1080p to 4K at High settings, a pattern consistent with a GPU that is severely overburdened by pixel count.

The scaling behavior is even more telling when examining the Low settings preset. At 1080p Low, the configuration achieves 106 FPS, which drops to 76 FPS at 1440p and 47 FPS at 4K. While the 1080p result is playable, the decline to 4K is drastic, losing 59 FPS or 56% of the performance. This steep curve suggests that the Arc B390's memory bandwidth and shading resources are exhausted quickly as resolution increases, regardless of the graphical complexity. The CPU, with its 6 cores and 12 threads, appears to have sufficient headroom at these frame rates, as the performance degradation is almost entirely attributable to the GPU's rendering limitations.

The Medium settings preset provides additional insight into the scaling pattern. The measured data includes minimum and maximum FPS values for this preset, showing 33 to 44 FPS at 4K, 53 to 71 FPS at 1440p, and 74 to 100 FPS at 1080p. The range between minimum and maximum FPS widens at lower resolutions, indicating that the GPU is less consistently saturated and frame times are more variable. At 4K Medium, the frame rate is nearly pinned to the minimum, suggesting the GPU is running at full capacity with little variance. This resolution scaling analysis points to a configuration where the Arc B390's 60.00 GPixel/s pixel rate and 120.0 GTexel/s texture rate are simply insufficient for higher resolutions in Downfall.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this configuration is achieved at 1080p with Low settings, which yields an average of 106 FPS. This is the only preset and resolution combination that exceeds the 100 FPS threshold, providing a smooth and responsive experience for a horror game where reaction time matters. The 1080p Medium preset, at 87 FPS average, is also viable and offers improved visual fidelity while maintaining a frame rate above 60 FPS, with a measured minimum of 74 FPS ensuring no drops below playable levels.

For users prioritizing visual quality over raw frame rate, the 1080p High preset at 71 FPS is acceptable, though it does sacrifice the headroom provided by Low settings. The high preset at 1440p, at 51 FPS, is borderline, as frame rates dip below the 60 FPS threshold that many players consider the minimum for smooth gameplay. The Ultra preset is not recommended at any resolution, as it produces only 44 FPS at 1080p and a nearly unplayable 20 FPS at 4K. The data clearly indicates that the Ultra preset is beyond the capabilities of the Arc B390, likely due to its 7.680 TFLOPS FP32 performance being insufficient for the added shader complexity.

The 4K resolution is effectively not viable for this game with this hardware, as even the Low preset only achieves 47 FPS. The Medium preset at 4K produces 39 FPS with a minimum of 33 FPS, which is below the standard playability threshold. Given the measured rows, the best experience per the data is unequivocally 1080p Low, with 1080p Medium as a strong alternative for those who can tolerate a 19 FPS average reduction for better visuals. The 1440p Medium preset, at 62 FPS, is the only 1440p option that maintains playable frame rates, though it still falls short of the 1080p experience.

The scaling from 1080p to 4K at each preset shows a consistent pattern: Low settings lose 59 FPS, Medium loses 48 FPS, High loses 39 FPS, and Ultra loses 24 FPS. This narrowing gap at higher presets indicates that the GPU is already saturated at 1080p Ultra, leaving little additional performance to lose at 4K.

How This Combo Ranks

The AMD Ryzen 5 5600GT and Intel Arc B390 combination ranks 2589 out of 2928 tested combos in Downfall, placing it in the bottom 12% of all configurations. This ranking is primarily driven by the GPU's weak performance, as the CPU's percentile ranking of 74 places it in the upper quartile of all processors. The disparity between the CPU's respectable standing and the GPU's 9th percentile ranking creates a severely imbalanced system where the graphics card is the definitive limiting factor.

The combo rank of 2589 indicates that 339 other tested combinations perform worse than this setup. However, given the GPU's nearest rivals include the NVIDIA GeForce GT 520MX and GeForce 800M, the Arc B390 is positioned alongside legacy integrated and entry-level discrete GPUs. The 1.3% performance delta over the GT 520MX and 1.5% over the GeForce 800M suggests that the Arc B390 only marginally outperforms these older parts in the 3DMark Steel Nomad DX12 benchmark, which correlates with the weak Downfall results.

In practical terms, this combo's rank means that most modern gaming PCs will outperform it by a significant margin. The 4K Ultra result of 20 FPS and the 1080p Ultra result of 44 FPS demonstrate that this configuration is not designed for high-fidelity gaming. The CPU's contribution to this rank is minimal, as its benchmark scores are within 0.5% of its nearest rivals, meaning the GPU is almost entirely responsible for the low ranking.

CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on the Zen 3 architecture, with a base clock of 3.60 GHz and a boost clock of 4.60 GHz. It features 16 MB of L3 cache and supports DDR4 memory with a dual-channel bus and 51.2 GB/s bandwidth. In the context of Downfall, a horror game released in 2016, this CPU provides more than adequate processing power, as the game's engine is likely not heavily threaded and the 6 cores handle the workload efficiently.

The CPU's benchmark scores indicate robust performance, with a Cinebench R23 multicore score of 17272 and a single-core score of 2438. The 3DMark scores show scaling from 913 in single-thread to 5554 in max-threads, indicating good multi-threading capabilities. The average benchmark score of 20733 places it in the 74th percentile among all CPUs, with nearest rivals including the Intel Core i5-12490F and Intel Xeon 6325P, all within 0.5% performance delta.

In this specific game, the CPU's role is to feed the GPU with draw calls and handle game logic. Given that the Arc B390 is the bottleneck at all resolutions, the CPU is likely underutilized. The 1080p Low result of 106 FPS suggests the CPU can handle frame rates well above what the GPU can deliver at higher settings. The CPU's 65 W TDP and 7 nm process node indicate it runs efficiently, but this does not translate to better Downfall performance because the GPU limits the frame rate. The 16 MB L3 cache and 512 KB L2 per core provide sufficient data locality for the game's assets, but the CPU's capabilities are not the determining factor in this configuration's modest results.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, built on Intel's 3 nm process node. It has 1536 shading units, 48 texture mapping units, and 24 raster operation units, along with 12 ray tracing cores. The GPU operates at a base clock of 300 MHz and boosts to 2500 MHz, with system-shared memory providing variable bandwidth. Its theoretical performance is 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16, with a pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s.

The GPU's benchmark results are poor, with a 3DMark Steel Nomad DX12 score of 1482, placing it in the 9th percentile of all GPUs. Its nearest rivals are the NVIDIA GeForce GT 520MX, GeForce 800M, GT 625 OEM, and GT 710, with performance deltas ranging from 1.3% to 2.7%. This positioning is critical to understanding the Downfall results, as the Arc B390 performs similarly to decade-old entry-level GPUs.

In Downfall, the GPU's limitations manifest across all resolutions and settings. The 24 ROPs are insufficient for high-resolution rasterization, which explains the steep decline from 106 FPS at 1080p Low to 47 FPS at 4K Low. The 120.0 GTexel/s texture rate is inadequate for High and Ultra presets, which likely introduce additional texture layers and higher-resolution textures. The system-shared memory, with bandwidth dependent on the system configuration, further constrains performance, particularly at 4K where memory bandwidth demands are highest.

The GPU's 80 W TDP and IGP form factor mean it shares power and thermal resources with the CPU, potentially limiting sustained boost clocks. The 2500 MHz boost clock may not be maintained under heavy load, which could explain the poor scaling from 1080p to 4K. The Arc B390's architecture supports DirectX 12 Ultimate and Vulkan 1.4, but this feature set does not compensate for the raw compute and memory bandwidth deficits that Downfall exposes. The data clearly shows that the GPU is the sole reason this combo ranks 2589 out of 2928, as the CPU is capable of far better performance with a more powerful graphics solution.
