Pc Building Simulator

Pc Building Simulator with an AMD Ryzen 5 3600 and Intel Arc B390 produces a heavily GPU-limited experience across all tested resolutions. The benchmark data shows a clear pattern: the Arc B390, which ranks in the 9th percentile of all GPUs, becomes the primary bottleneck as resolution increases, while the Ryzen 5 3600’s 6-core/12-thread configuration provides sufficient headroom for this simulation title. The measured frames per second drop dramatically from 1080p to 4K, and the scaling between settings presets reveals that this combo is best suited for lower resolutions and medium-to-low graphical fidelity.

Resolution Scaling

The performance degradation from 1080p to 4K is steep and consistent across all settings, confirming that the Intel Arc B390 is the limiting component in this pairing. At Low settings, the average FPS falls from 125 at 1920x1080 to 79 at 2560x1440, a 37% reduction, and then to 41 at 3840x2160, which is another 48% drop from the 1440p figure. This near-halving of frame rates at each resolution step indicates that the GPU’s fillrate and shading capabilities are being saturated, as the Arc B390’s 24 ROPs and 60.00 GPixel/s pixel rate cannot keep pace with the increasing pixel count.

At Medium settings, the same trend is visible but with slightly smaller percentage drops: 88 FPS at 1080p falls to 56 FPS at 1440p (a 36% reduction), and then to 29 FPS at 4K (a 48% reduction from 1440p). The High preset shows 62 FPS at 1080p, 39 FPS at 1440p (37% lower), and 21 FPS at 4K (46% lower). Ultra settings are the most demanding, with 59 FPS at 1080p, 38 FPS at 1440p (36% lower), and 20 FPS at 4K (47% lower). The consistent 36-37% drop from 1080p to 1440p and 46-48% drop from 1440p to 4K across all presets points to a purely resolution-bound scenario, where the CPU’s role diminishes as the GPU struggles to fill frames.

The data suggests that 1080p is the only viable resolution for smooth gameplay, and even then, only at Low or Medium settings. At 1440p, the combo falls below 60 FPS on every preset, with Ultra dipping to 38 FPS. At 4K, all settings produce sub-30 FPS results, making the experience borderline unplayable for any action-oriented use case. The fact that the gap between 1080p and 1440p is proportionally similar to the gap between 1440p and 4K indicates that the Arc B390’s memory bandwidth, listed as "System Dependent" due to its shared memory architecture, is not providing any relief at higher resolutions. The GPU’s 7.680 TFLOPS of FP32 compute is simply insufficient for 4K workloads in this game.

Settings Recommendations

The measured rows clearly indicate that the Low preset at 1920x1080 is the optimal configuration for this combo, delivering 125 FPS average. This is the only setting and resolution combination that approaches high-refresh-rate territory. Medium at 1080p is a reasonable alternative, providing 88 FPS, which is still comfortably above 60 FPS, and it offers better visual fidelity than Low. The step from Low to Medium costs 37 FPS at 1080p, which is a significant trade-off, but the resulting 88 FPS remains playable.

High at 1080p yields 62 FPS, which is just above the 60 FPS threshold, but the improvement over Medium is marginal given the performance cost. Ultra at 1080p drops to 59 FPS, which is technically playable but not ideal, and the visual gains over High are unlikely to justify the 3 FPS difference. For users prioritizing smoothness, Low at 1080p is the clear winner. For those wanting a balance, Medium at 1080p offers the best experience per the measured rows, as it keeps frame rates high while providing a moderate visual upgrade.

At 1440p, the situation is more constrained. Medium is the only preset that breaks 50 FPS, hitting 56 FPS, while Low reaches 79 FPS. However, even Low at 1440p does not match the 1080p Medium experience in terms of frame rate. The data suggests that 1440p is only viable at Low settings, and even then, the 79 FPS average is lower than the 1080p Medium score. At 4K, no setting is recommended, as even Low produces only 41 FPS, which is below the 60 FPS target for smooth gameplay. The Medium preset at 4K shows a minimum FPS of 25 and a maximum of 34, indicating frame time inconsistency that would be noticeable.

GPU Role

The Intel Arc B390 is the dominant factor in these results, and its specifications explain why. With a base clock of 300 MHz and a boost clock of 2500 MHz, the GPU’s 1536 shading units and 48 TMUs are working at a significant disadvantage in this simulation title. The GPU’s percentile rank of 9 means it outperforms only a small fraction of tested graphics cards, and its nearest rivals in the benchmark database include the NVIDIA GeForce GT 520MX and GT 710, which are entry-level parts from previous generations. The Arc B390’s 1.3% deltaPct over the GT 520MX and 2.7% over the GT 710 confirms that it sits at the very bottom of the performance spectrum.

The GPU’s memory configuration is "System Shared," meaning it relies on system RAM rather than dedicated VRAM. This is a critical limitation for Pc Building Simulator, which likely benefits from dedicated memory bandwidth. The memory bandwidth is listed as "System Dependent," which suggests that performance can vary based on the CPU’s memory controller and the speed of the installed DDR4 memory. The Ryzen 5 3600 supports dual-channel DDR4 with a theoretical bandwidth of 51.2 GB/s, but the shared memory architecture means the GPU competes with the CPU for this bandwidth, potentially causing stutters at higher resolutions.

The 3DMark Steel Nomad DX12 score of 1482 reinforces the GPU’s weak position. This score places the Arc B390 in the 9th percentile, and the measured FPS in Pc Building Simulator aligns with this low benchmark result. The GPU’s 12 RT cores and DirectX 12 Ultimate support are irrelevant here, as the game’s simulation genre does not appear to stress ray tracing or advanced DX12 features. The 80 W TDP and IGP slot width indicate that this is a power-efficient but low-performance part, and the data shows that it cannot handle 1440p or 4K in this game at playable frame rates.

How This Combo Ranks

The combo rank in this game is 2650 out of 3002 tested combinations, placing it in the bottom 12% of all CPU-GPU pairings. This low ranking is almost entirely attributable to the GPU, as the Ryzen 5 3600 is a mid-range processor that performs adequately in isolation. The rank of 2650 means that 352 other combos delivered worse performance, but the vast majority of systems tested were faster. This position is consistent with the GPU’s 9th percentile ranking, which suggests that the Arc B390 is the primary drag on the combo’s overall standing.

Compared to other combos in the database, this pairing is clearly not optimized for Pc Building Simulator. The GPU’s nearest rivals, such as the GeForce GT 710, are legacy parts that would struggle with modern titles, and the fact that the Arc B390 only beats the GT 710 by 2.7% in synthetic benchmarks reinforces that this is a low-end solution. The CPU’s strong synthetic scores, including a Cinebench R23 multi-core score of 15045 and a PassMark multi-thread score of 17700, do not translate into gaming performance when paired with such a weak GPU. The data indicates that the combo rank would improve substantially with a more capable graphics card, but as measured, this pairing is best suited for 1080p Low or Medium settings.

CPU Role

The AMD Ryzen 5 3600 provides a solid foundation for this game, but its contributions are largely masked by the GPU bottleneck. The CPU’s 6 cores and 12 threads, based on the Zen 2 architecture and codenamed Matisse, are more than sufficient for Pc Building Simulator’s simulation workload. The base clock of 3.60 GHz and boost clock of 4.20 GHz are respectable, and the 32 MB of shared L3 cache helps with game logic and asset streaming. The CPU’s percentile rank of 71 places it above the majority of tested processors, and its nearest rivals include the Intel Core i7-1260P and Core i5-11400, with deltaPct values of 0.2% and -0.2%, respectively, indicating near-identical average benchmark scores.

The CPU’s synthetic benchmarks are strong: a Geekbench multi-core score of 7372 and a single-core score of 1536, alongside a Cinebench R20 multi-core score of 6318. These numbers suggest that the CPU is not a limiting factor in this game. However, the measured FPS data shows no meaningful difference between the CPU’s performance at different resolutions, which further confirms that the GPU is the bottleneck. At 1080p Low, the CPU can feed the GPU enough frames to reach 125 FPS, but at 4K Ultra, the CPU is likely waiting for the GPU to finish rendering each frame.

The CPU’s memory support for DDR4 at dual-channel with 51.2 GB/s bandwidth is adequate, but the shared memory architecture of the GPU means that the CPU’s memory controller is also handling graphics data. This could introduce latency, but the benchmark results do not show a clear CPU-related bottleneck at any resolution. The data suggests that upgrading the GPU would yield significant FPS gains, while upgrading the CPU would provide no tangible benefit in this specific title with this GPU.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce an average of 125 FPS, which is the highest measured score in the entire dataset. Medium settings average 88 FPS, with a minimum of 75 FPS and a maximum of 102 FPS, indicating a stable frame delivery. High settings average 62 FPS, while Ultra settings average 59 FPS. The step from High to Ultra is only 3 FPS, suggesting that Ultra offers no meaningful performance advantage over High in this resolution.

At 2560x1440, performance drops significantly. Low settings average 79 FPS, which is still above 60 FPS but 37% lower than the 1080p Low score. Medium settings average 56 FPS, with a minimum of 47 FPS and a maximum of 64 FPS, placing it below the 60 FPS threshold. High settings average 39 FPS, and Ultra settings average 38 FPS. The difference between High and Ultra at 1440p is just 1 FPS, indicating that the GPU is fully saturated and visual settings have minimal impact on the frame rate.

At 3840x2160, the combo is unable to maintain playable frame rates on any preset. Low settings average 41 FPS, which is the only 4K result above 30 FPS. Medium settings average 29 FPS, with a minimum of 25 FPS and a maximum of 34 FPS. High settings average 21 FPS, and Ultra settings average 20 FPS. The data shows that the GPU’s pixel rate of 60.00 GPixel/s is insufficient for 4K, as even the lowest settings cannot reach 60 FPS. The Medium preset’s minimum FPS of 25 highlights the frame pacing issues at this resolution, making the experience feel stuttery. Overall, the measured FPS breakdown confirms that this combo is only suitable for 1080p gaming, with Low or Medium settings being the only viable options for a smooth experience.
