Pc Building Simulator

Pc Building Simulator, a simulation title from 2019, presents a unique workload that is far more dependent on CPU logic and system memory than on graphical fidelity. The measured performance of the AMD Ryzen 9 5900X paired with the Intel Arc B390 illustrates this dynamic clearly, revealing a system where the processing core is the primary driver of frame rates, while the graphics processor struggles to keep pace at higher resolutions. The data indicates a substantial performance ceiling imposed by the GPU, particularly when pushing towards 4K, but also shows that the 12-core processor ensures the simulation's logic never becomes the bottleneck.

Resolution Scaling

The measured FPS data shows a pronounced and consistent drop in performance as resolution increases from 1920x1080 to 3840x2160. At the Low settings preset, the average frame rate falls from 125 FPS at 1080p to 79 FPS at 1440p, a significant reduction of 46 FPS. Moving from 1440p to 4K at the same Low preset, the average drops further to 41 FPS, halving the 1440p figure. This steep decline is a classic indicator that the graphics processor is the limiting component; a CPU-bound scenario would show far less variance across resolutions.

The scaling pattern becomes even more telling at higher graphical presets. At the High preset, the average FPS drops from 62 at 1080p to 39 at 1440p, and then to 21 at 4K. This shows that the performance cost of increasing resolution is not linear but exponential, placing an overwhelming load on the Intel Arc B390. The gap between the Low and High presets at 4K is 20 FPS (41 vs 21), while at 1080p, the same preset change yields a 63 FPS difference (125 vs 62). This compression of the preset performance gap at higher resolutions confirms that the GPU is saturated and its limitations are the primary factor dictating the frame rate.

The data suggests that the 1080p resolution is the only viable target for this combo if the goal is to maintain a high refresh rate experience. At 1440p, the system can still deliver playable frame rates on lower settings, but the 4K resolution proves to be too demanding. The benchmark results indicate that the Arc B390, with its score in the 9th percentile of all GPUs, simply does not possess the raw pixel throughput necessary to handle the increased workload of 4K, regardless of the powerful CPU sitting beside it. The system is unequivocally GPU-limited at 4K, and the scaling data serves as a clear warning against targeting that resolution for a smooth experience.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, built on a 3 nm process. Its role in this game's results is defined by its modest specifications and its low performance percentile. The GPU’s benchmark score is 1482 in the 3DMark Steel Nomad DX12 test, placing it in the 9th percentile of all GPUs, which is a stark indicator of its entry-level positioning. Its nearest rivals in benchmark scores, such as the NVIDIA GeForce GT 520MX and the GeForce 800M, are all older, low-power mobile parts, reinforcing the assessment that the Arc B390 is not designed for demanding gaming workloads.

The GPU operates with a base clock of 300 MHz and a boost clock of 2500 MHz, and it features 1536 shading units, 48 texture mapping units, and 24 render output units. It also includes 12 ray tracing cores. However, its memory configuration is a critical weakness: it uses "System Shared" memory, meaning it relies on the system's main memory rather than dedicated VRAM. The memory bandwidth is listed as "System Dependent," which in practice means the GPU's performance is tied to the speed and capacity of the system's DDR4 RAM, a shared resource that can create performance bottlenecks. This configuration, paired with a peak FP32 throughput of 7.680 TFLOPS, explains why the GPU struggles to maintain high frame rates.

Within the context of Pc Building Simulator, the GPU's role is to render the 3D environment and the various components. The benchmark results show that at 1080p with Low settings, the GPU can manage an average of 125 FPS, which is sufficient for a smooth simulation. However, as the settings increase, the GPU's limitations become apparent. At 1080p Ultra, the average FPS drops to 59, and at 4K Ultra, it falls to 20 FPS. The data shows that the Arc B390 is a capable part for very light graphical loads, but its performance is a severe constraint for this combo at higher resolutions and settings, acting as the primary bottleneck above 1080p.

CPU Role

The AMD Ryzen 9 5900X is a high-end desktop processor from the 5000 series, built on the Zen 3 architecture (codename Vermeer) and fabricated on a 7 nm process. Its role in this game's results is to handle the complex simulation logic, which includes managing the state of countless virtual components and system interactions. With 12 cores and 24 threads, it has substantial parallel processing power, evidenced by its strong multi-threaded benchmark scores, such as 16,262 in Cinebench R23 multicore and 14,118 in Geekbench multicore. The CPU's high performance is also reflected in its 87th percentile ranking among all CPUs.

The processor's base clock of 3.70 GHz and boost clock of 4.80 GHz provide strong single-threaded performance, which is crucial for the primary game logic thread. Its benchmark scores in single-threaded tests, including 1,527 in Cinebench R23 and 2083 in Geekbench, indicate it is more than capable of handling the game's core calculations. In the measured FPS data, the CPU's strength is evident in the high frame rates achievable at 1080p Low, where the GPU is not the limiting factor. The 125 FPS average at this setting demonstrates that the CPU can feed the GPU with enough data to achieve high performance.

The data suggests that the Ryzen 9 5900X is never the bottleneck in this pairing. Even at 4K Ultra, where the average FPS is a low 20, the limitation is clearly the GPU. The CPU's role is to ensure that the game's logic is updated correctly and quickly, and the benchmark results indicate it does so with ease. The processor's high core count and thread count, along with its 64 MB of L3 cache, provide a massive computational headroom that the game does not fully utilize. The performance difference between this CPU and its nearest rivals, such as the Intel Core Ultra 7 366H, is negligible (0.3% difference in average benchmark score), confirming that the 5900X is a top-tier part whose capabilities far exceed the demands of this title.

Measured FPS Breakdown

The measured FPS data provides a granular look at the combo's performance across a matrix of resolutions and settings. At 1920x1080, the system shows its best performance. With Low settings, the average FPS is 125, which is a very smooth experience. Medium settings reduce the average to 88 FPS, with a min of 75 and a max of 102. High settings yield an average of 62 FPS, and Ultra settings bring the average down to 59 FPS. This shows that at 1080p, all presets are technically playable, though the jump from Low to Medium is a 37 FPS drop, indicating a significant increase in GPU load.

Moving to 2560x1440, the performance drops across the board. The Low preset averages 79 FPS, which is still a good result. Medium settings average 56 FPS, with a min of 47 and a max of 64. The High preset average is 39 FPS, and the Ultra preset average is 38 FPS. This resolution presents a clear choice: for a smooth experience, users must stick to Low or Medium settings. The High and Ultra presets fall below the 60 FPS threshold, which can be noticeable in a simulation game where menu navigation and component manipulation need to feel responsive.

At 3840x2160, the GPU is heavily overmatched. The Low preset is the only one that approaches playability, with an average of 41 FPS. Medium settings average 29 FPS, with a min of 25 and a max of 34. High settings average 21 FPS, and Ultra settings average just 20 FPS. These results are consistently low and indicate that 4K is not a viable resolution for this hardware combo in this game. The data shows a clear pattern: each step up in resolution or settings leads to a substantial drop in average FPS, with the most dramatic losses occurring when the resolution increases to 4K.

How This Combo Ranks

The combination of the AMD Ryzen 9 5900X and the Intel Arc B390 is ranked 2650 out of 3002 tested combos in Pc Building Simulator. This ranking places it in the lower 12th percentile of all tested configurations, indicating that it is a below-average performer for this specific game. This low rank is almost entirely attributable to the GPU, which is a severe bottleneck. The CPU, by contrast, is a top-tier part, ranking in the 87th percentile of all CPUs, but its performance is wasted by the GPU's inability to render frames quickly.

The combo's rank is a direct consequence of the GPU's low performance ceiling. The Arc B390's benchmark score is in the 9th percentile of all GPUs, and its nearest rivals are all entry-level parts from years past. This means that while the CPU is capable of delivering high frame rates, the GPU cannot keep up, especially at higher resolutions and settings. The measured FPS data supports this, showing that the combo’s performance is heavily dependent on the GPU's workload.

In the context of the database, this rank of 2650 out of 3002 suggests that most other tested combinations will outperform this one in Pc Building Simulator. Users with a more balanced system, or even a system with a lower-end CPU but a more capable GPU, would likely see better results. The data underscores the importance of a balanced build; pairing a high-end processor with an entry-level integrated GPU creates a significant performance imbalance, resulting in a poor overall ranking for this specific game.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution. For a 1920x1080 display, the Low preset offers the highest average frame rate at 125 FPS, providing the most responsive experience. However, if visual fidelity is a priority, the Medium preset is a strong recommendation, as its 88 FPS average remains well above the 60 FPS threshold for smooth gameplay. The High and Ultra presets, while playable at 62 and 59 FPS respectively, offer diminishing returns for the significant drop in frame rate.

At 2560x1440, the choice becomes more constrained. The Low preset is the best option for a fluid experience, with an average of 79 FPS. The Medium preset is a compromise, offering an average of 56 FPS, which is playable but with noticeable frame pacing issues in more demanding scenes. The High and Ultra presets should be avoided at this resolution, as their averages of 39 and 38 FPS respectively will result in a stuttery and less enjoyable experience.

For 3840x2160, no settings preset is recommended for a good experience. Even the Low preset only manages an average of 41 FPS, which is below the standard for smooth gameplay. The Medium, High, and Ultra presets are all in the 20-29 FPS range, which is not acceptable for a simulation game. The data indicates that users should either lower their resolution to 1440p or 1080p or consider a hardware upgrade to make 4K a viable option. The best overall experience, balancing performance and visual quality, is achieved at 1080p with the Medium settings preset, which delivers a 88 FPS average with a minimum of 75 FPS.
