Pc Building Simulator

Pc Building Simulator is a simulation title that places the player in control of a PC repair and assembly shop, and the measured performance of the AMD Ryzen 5 4600G paired with the Intel Arc B390 shows a system heavily constrained by its graphics component. The data indicates a configuration that is playable at 1080p with adjusted settings, but which struggles to maintain fluid frame rates at higher resolutions, making it a practical choice for entry-level simulation play rather than a high-end gaming rig.

Resolution Scaling

The performance drop from 1080p to 4K is substantial and reveals the GPU as the primary limiting factor in this configuration. At 1080p Low settings, the system produces an average of 125 FPS, which is a strong result. Moving to 1440p Low drops the average to 79 FPS, a reduction of 46 FPS, and at 4K Low the average falls to 41 FPS. This scaling pattern — a halving of performance from 1080p to 4K — is a classic indicator of a GPU-bound workload, where the render resolution outpaces the graphics processor's capabilities.

The trend is consistent across all settings presets. On High settings, the average frame rate goes from 62 FPS at 1080p to 39 FPS at 1440p, and then down to 21 FPS at 4K. The Ultra preset follows a similar trajectory, with averages of 59 FPS, 38 FPS, and 20 FPS at 1080p, 1440p, and 4K respectively. The data shows that the gap between 1080p and 1440p is significant, but the step from 1440p to 4K is devastating for playability, often cutting frame rates nearly in half again.

This steep decline suggests that the Intel Arc B390's rendering pipeline is saturated well before 4K resolution. The GPU, which sits in the 9th percentile of all GPUs according to its benchmark score, simply does not have the fill rate or shading power to handle the pixel count of 3840x2160. The 1080p to 1440p drop is more manageable, but still severe, with the system losing roughly 37-40% of its performance on Low and High presets. For a builder looking at this data, the conclusion is clear: 1080p is the intended operating range for this combo, 1440p is a stretch that requires low settings, and 4K is not a viable target for smooth gameplay.

GPU Role

The Intel Arc B390 is the decisive factor in this system's gaming performance, and the benchmark results paint a picture of a very modest integrated graphics solution. The GPU's average benchmark score of 1482 places it in the 9th percentile of all GPUs, which is remarkably low. Its nearest rivals in the data are legacy mobile parts like the NVIDIA GeForce GT 520MX and the NVIDIA GeForce 800M, with delta percentages of 1.3% and 1.5% respectively. This positioning indicates that the Arc B390's raw 3DMark Steel Nomad DX12 score of 1482 is on par with graphics solutions from over a decade ago.

The GPU's specifications align with this performance level. It features 1536 shading units, 48 texture mapping units, and 24 raster output units, with 12 ray tracing cores. The boost clock is rated at 2500 MHz, while the base clock is 300 MHz, and the memory is "System Shared," meaning it relies on the system's DDR4 memory rather than dedicated VRAM. The memory bandwidth is listed as "System Dependent," which means performance can vary based on the CPU's memory configuration. In this case, the Ryzen 5 4600G supports dual-channel DDR4 with a theoretical memory bandwidth of 51.2 GB/s, which is the memory pool the GPU must draw from.

The measured FPS data confirms that this GPU is the bottleneck. At 1080p Low, the system achieves 125 FPS, which shows the GPU can handle light loads. However, at 4K Ultra, the average drops to 20 FPS, demonstrating that the rendering units are overwhelmed by higher resolutions and complex shading. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are not sufficient for 4K gaming. The data suggests that the Arc B390 is a capable part for basic 2D workloads and very light 3D tasks, but for a game like Pc Building Simulator at 1080p, it performs adequately only on lower presets.

Settings Recommendations

Based on the measured frame rates, the optimal experience for this configuration is found at 1080p with the Low settings preset. The data shows an average of 125 FPS at this setting, which is smooth and responsive. The Medium preset at 1080p yields an average of 88 FPS with a minimum of 75 FPS and a maximum of 102 FPS, which is also playable and offers a better visual experience for only a 37 FPS penalty. For players who prioritize visual fidelity over frame rate, the High preset at 1080p provides 62 FPS, which is still within the range of playability for a simulation game, though it is less fluid.

The Ultra preset at 1080p is not recommended, as it only produces an average of 59 FPS, a marginal gain over High in terms of visuals but a significant drop from Medium. The data indicates that the jump from Low to Medium is the sweet spot, offering a substantial improvement in image quality while maintaining a playable frame rate. At 1440p, only the Low preset is viable, with an average of 79 FPS. The Medium preset at 1440p drops to 56 FPS, which is playable but not ideal, and High and Ultra fall to 39 FPS and 38 FPS respectively, which are too low for smooth gameplay. At 4K, all presets are below 41 FPS, with Ultra at 20 FPS, making this resolution unsuitable for this hardware.

The data suggests that players should stick to 1080p and use the Medium preset for a balanced experience. The minimum frame rate of 75 FPS on Medium at 1080p ensures that there are no major stutters, and the average of 88 FPS leaves headroom for the simulation's CPU-bound calculations. Lowering to Low at 1080p is the choice for competitive or high-refresh-rate play, but for a game about building PCs, the visual detail of Medium is more engaging.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the system's capabilities across resolutions and settings.

At 1920x1080, the system performs best. The Low preset achieves an average of 125 FPS. The Medium preset produces an average of 88 FPS, with a minimum of 75 FPS and a maximum of 102 FPS. The High preset drops to an average of 62 FPS, and the Ultra preset yields an average of 59 FPS. The spread from Low to Ultra is 66 FPS, showing a significant impact of settings on performance at this resolution.

Moving to 2560x1440, the averages drop considerably. The Low preset averages 79 FPS. The Medium preset averages 56 FPS, with a minimum of 47 FPS and a maximum of 64 FPS. The High preset averages 39 FPS, and the Ultra preset averages 38 FPS. The difference between High and Ultra at 1440p is negligible, at just 1 FPS, suggesting that the Ultra preset's additional effects are not rendering effectively due to the GPU's limitations.

At 3840x2160, the system is clearly overburdened. The Low preset averages 41 FPS. The Medium preset averages 29 FPS, with a minimum of 25 FPS and a maximum of 34 FPS. The High preset averages 21 FPS, and the Ultra preset averages 20 FPS. These numbers are below the threshold for smooth gameplay, and the data shows that even the minimum frame rate on Medium at 4K (25 FPS) is not acceptable for a consistent experience.

The overall combo rank in game is 2650 out of 3002 combinations, indicating that this configuration is in the lower percentile of tested systems. This ranking reflects the weak GPU performance, as the CPU is a more capable part. The data shows that the system is usable for 1080p gaming but is heavily reliant on the user selecting appropriate settings to maintain playability.

CPU Role

The AMD Ryzen 5 4600G plays a secondary but important role in this configuration. While the GPU is the primary bottleneck, the CPU's performance ensures that it does not become a limiting factor in most scenarios. The processor has 6 cores and 12 threads, with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. It is built on the Zen 2 architecture (Renoir) using a 7 nm process, and it features 8 MB of shared L3 cache.

The CPU's benchmark results show it is a solid mid-range part. Its average benchmark score is 17507, placing it in the 71st percentile of all CPUs, which is a stark contrast to the GPU's 9th percentile ranking. In multi-threaded tests, it scores 13593 in Cinebench R23 multicore and 5709 in Cinebench R20 multicore. Its single-thread performance is respectable, with scores of 1919 in Cinebench R23 singlecore and 726 in 3DMark single-thread. The nearest rivals to the CPU are the AMD Ryzen 3 PRO 5355GE (0.1% ahead), the AMD Ryzen 3 8300GE (0.6% behind), and the Intel Core 7 150U (0.6% ahead), showing that the 4600G is tightly grouped with similar low-power parts.

In Pc Building Simulator, which is a simulation game that typically relies on single-thread performance for game logic and physics, the CPU's 3DMark 2-thread score of 1430 and 4-thread score of 2732 are adequate. The data shows that at 1080p Low, the system achieves 125 FPS, which indicates that the CPU can feed frames to the GPU at a high rate. However, the CPU's 3DMark max-thread score of 4889 and 16-thread score of 4863 suggest that it is not a high-end part for heavily threaded workloads, but for this game, it is sufficient.

The CPU's integrated Radeon Vega 7 graphics is not used in this configuration, as the system relies on the Intel Arc B390. The CPU's memory support for dual-channel DDR4 at 51.2 GB/s bandwidth is the data path for the GPU's system-shared memory. The CPU's performance is not the reason for low frame rates in this game; the GPU is. The CPU's 71st percentile ranking confirms that it is a capable processor, and its 6-core, 12-thread layout provides enough parallel processing for the simulation's background tasks. The bottleneck is clearly the Intel Arc B390, which sits at the 9th percentile and cannot keep up with the CPU's output at higher resolutions.
