Pc Building Simulator

Pc Building Simulator presents an unusual benchmark scenario when paired with the AMD Ryzen 7 7800X3D and Intel Arc B390. The measured frame rates reveal a configuration that is heavily constrained by the graphics solution, yet the data also shows how the processor’s capabilities become more relevant at lower resolutions. This analysis breaks down the measured FPS across resolutions and settings, examining the roles of the CPU and GPU, and contextualizing the combo’s standing against other tested configurations.

Resolution Scaling

The progression from 1080p to 4K shows a dramatic and consistent decline in frame rates, which is the clearest indicator of where the bottleneck lies in this system. At 1080p with Low settings, the combo produces an average of 125 FPS. Moving to 1440p at the same settings, the average drops to 79 FPS, a reduction of 46 frames. The climb to 2160p at Low settings further reduces the average to 41 FPS. This scaling pattern shows that the performance ceiling is being lowered significantly as pixel count increases.

The drop from 1080p to 1440p represents a 36.8% decrease in average FPS, while the transition from 1440p to 2160p yields an even steeper 48.1% decrease. This non-linear scaling is a classic symptom of a GPU-bound scenario. As the resolution increases, the rendering workload expands substantially, and the Arc B390's limited processing power is unable to keep pace. The data suggests that the GPU is the primary limiting component at all resolutions, but its constraint becomes far more severe as the pixel count approaches 4K.

Comparing High settings across resolutions reinforces this trend. The average FPS at 1080p High is 62, which falls to 39 at 1440p, and finally to 21 at 2160p. The difference between 1080p and 1440p is a 23 FPS drop, while the difference between 1440p and 2160p is an 18 FPS drop. While the absolute numbers are lower, the percentage losses are similar, indicating that the GPU workload scales proportionally with resolution regardless of the quality preset.

The data points to a system where the CPU is not the primary constraint. The Ryzen 7 7800X3D, with its 8 cores and 16 threads, is more than capable of feeding frames to the GPU at lower resolutions. The fact that the FPS drops so precipitously when moving from 1080p to 1440p and again to 2160p indicates that the Intel Arc B390's rendering throughput is the limiting factor. The CPU's headroom is only fully utilized at 1080p Low where the GPU can still produce a high number of frames.

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. Its role in this game is defined by its memory configuration and clock speeds. The GPU's memory size, type, and bus width are all listed as "System Shared," meaning it relies on the system's main memory rather than dedicated VRAM. Its memory bandwidth is similarly "System Dependent," which means its performance is tied to the speed and configuration of the host system's RAM.

This shared memory arrangement is a critical factor in understanding the performance results. Unlike a discrete GPU with dedicated high-bandwidth memory, the B390 must compete with the CPU for memory access. The base clock is 300 MHz, with a boost clock of 2500 MHz. The substantial difference between these clocks indicates that the GPU can scale its frequency dynamically, but it likely spends much of its time at lower clocks due to thermal or power constraints, given its 80 W TDP and integrated design.

The benchmark data for the GPU shows a single score: 1482 in 3dmark_steel_nomad_dx12. This score places the B390 in the 9th percentile of all GPUs, which is a very low standing. Its nearest rivals include the NVIDIA GeForce GT 520MX with a score of 1463 and a deltaPct of 1.3, and the NVIDIA GeForce GT 710 with a score of 1443 and a deltaPct of 2.7. These are all extremely dated, low-end graphics solutions, indicating that the B390's raw rendering power is minimal.

In Pc Building Simulator, this translates to the measured frame rates. The GPU's low compute power is the reason why 4K Ultra settings produce an average of only 20 FPS. Even at 1080p, the GPU struggles to maintain high frame rates at higher quality presets, with Ultra settings yielding an average of 59 FPS. The benchmark results indicate that this GPU is best suited for low-resolution or low-detail gaming, and the measured data confirms that it becomes a severe bottleneck in more demanding scenarios.

How This Combo Ranks

The combination of the Ryzen 7 7800X3D and the Intel Arc B390 ranks at 2650 out of 3002 tested combos in Pc Building Simulator. This places the configuration in the bottom 12% of all tested systems, which is a low standing that reflects the GPU's limitations. The data shows that this combo is not well-balanced for this game, as the CPU's high-end performance is effectively wasted due to the GPU's inability to render frames at a comparable pace.

The combo's rank is a direct consequence of the GPU's benchmark scores. The Arc B390's 9th percentile ranking among all GPUs drags the entire system down. While the CPU is a top-tier part, the overall system performance is dictated by the weakest link, which is the GPU. This result highlights that pairing a high-end processor with a low-end integrated GPU can produce a system that performs worse than many mid-range laptops or desktops with balanced components.

To provide context, the CPU itself has an 83rd percentile ranking against all CPUs, meaning it is faster than the vast majority of processors. However, this advantage is not realized in this game because the GPU cannot translate the CPU's processing power into higher frame rates. The combo rank of 2650 clearly indicates that the system is fundamentally limited by its graphics solution. A more balanced pairing, even with a much weaker CPU, would likely achieve a higher rank in this specific title.

It features 8 cores and 16 threads, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. Its cache configuration includes a large 96 MB shared L3 cache, which is a defining feature of the X3D series. The CPU supports DDR5 memory on a dual-channel bus, with a memory bandwidth of 83.2 GB/s.

In synthetic benchmarks, the CPU performs exceptionally well. Its Cinebench R23 multicore score is 16817, and its single-core score is 1713. Its Geekbench multicore and single-core scores are 15610 and 2426, respectively. The processor's average benchmark score is 33079, placing it in the 83rd percentile of all CPUs. Its nearest rivals include the AMD Ryzen 7 8700G and Intel Core i7-13650HX, both with an average score of 33089 and a deltaPct of 0.

Despite this strong CPU performance, the measured FPS in Pc Building Simulator shows that the processor is not the limiting factor. The frame rates are consistently low at higher resolutions, which would not be the case if the CPU were the bottleneck. At 1080p Low, the system achieves 125 FPS, which is a solid result that indicates the CPU can handle the game's simulation logic and physics at that level.

However, as the resolution increases, the FPS drops, revealing that the GPU is unable to keep up. The CPU's role in this combo is to provide ample headroom, ensuring that it never becomes the source of a frame rate cap. The data shows that the Ryzen 7 7800X3D is more than sufficient for this game, and its performance is essentially wasted in this pairing because the GPU cannot leverage its full potential.

Settings Recommendations

Based on the measured data, the optimal settings for this combo depend heavily on the target resolution and desired frame rate. For a smooth experience at 1080p, the Low preset provides the highest average FPS at 125, which is well above the 60 FPS threshold for most displays. The Medium preset at 1080p is also a viable option, with an average FPS of 88 and a minimum of 75, ensuring consistent frame times above 60 FPS.

At 1440p, the settings need to be more conservative. The Low preset yields an average of 79 FPS, which is still playable, but the Medium preset drops to an average of 56 FPS, with a minimum of 47. For players who prioritize a stable 60 FPS, Low settings at 1440p are the only reliable choice. The High and Ultra presets at 1440p produce averages of 39 and 38 FPS respectively, which are not recommended for a fluid experience.

At 4K, none of the settings provide a playable frame rate for most users. The Low preset has an average of 41 FPS, which may be acceptable for slower-paced simulation games, but the Medium, High, and Ultra presets drop to 29, 21, and 20 FPS respectively. The data suggests that 4K is not a viable resolution for this combo, and users should stick to 1080p or 1440p for a better experience.

For the best balance of visual quality and performance, the Medium preset at 1080p is the recommended choice. It offers a significant visual improvement over Low while maintaining an average FPS of 88, which is comfortably above the 60 FPS target. The minimum FPS of 75 ensures that there are no significant frame drops during gameplay. This setting provides the most stable and visually appealing experience that the hardware can deliver.
