GPU Role

The Intel Arc B390 is the defining component in this system's gaming performance. Its role is characterized by a very low performance ceiling, as indicated by its 9th percentile ranking among all GPUs. The graphics processor, built on the Xe3-LPG architecture, has a base clock of 300 MHz and a boost clock of 2500 MHz. Despite the high boost clock, the raw computational throughput is limited, with an FP32 performance of 7.680 TFLOPS.

The memory configuration is unique and critical to its performance profile. The B390 uses "System Shared" memory, meaning it relies on the system's DDR4 RAM rather than dedicated VRAM. The memory bandwidth is listed as "System Dependent," which means its performance is contingent on the CPU's memory controller and the speed of the installed RAM. In this case, the Ryzen 7 5700 supports dual-channel DDR4 with a theoretical bandwidth of 51.2 GB/s. This shared architecture explains why the GPU's performance scales so dramatically with graphical load.

In Pc Building Simulator, the GPU's limitations are immediately apparent. At 4K Ultra settings, the combo averages only 20 FPS. At 1080p Ultra, it averages 59 FPS. The benchmark data shows that the GPU is the primary constraint, as the frame rates are consistently low even when the CPU has ample headroom. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are modest figures, but for a simulation game that may render complex 3D scenes with many objects, these limits are quickly reached. The GPU's performance is so low that it sits just 1.3% above the NVIDIA GeForce GT 520MX in synthetic benchmarks, a GPU from a much earlier era.

Resolution Scaling

The measured FPS data reveals a classic GPU-bound scaling pattern. The Intel Arc B390's performance is heavily dependent on the number of pixels rendered. Moving from 1920x1080 to 2560x1440 and then to 3840x2160 shows a consistent and significant drop in frame rates across all settings.

At Low settings, the average FPS drops from 125 at 1080p to 79 at 1440p and then to 41 at 4K. This is a 67% reduction from 1080p to 4K. The scaling is not linear; the jump from 1440p to 4K (a 2.25x increase in pixel count) results in a 48% drop in frame rate (from 79 to 41 FPS). This indicates that the GPU's fillrate and memory bandwidth are being exhausted.

At High settings, the pattern is similar but with lower absolute numbers. The average FPS falls from 62 at 1080p to 39 at 1440p and 21 at 4K. The performance at 4K High is essentially unplayable. The difference between Medium and High settings also narrows as resolution increases, suggesting that the GPU is hitting a hard computational wall.

This scaling behavior confirms that the limiting component is the GPU. The Ryzen 7 5700, with its 8 cores and 16 threads, is not the bottleneck. If the CPU were the limit, the frame rates would be more consistent across resolutions. Instead, the data shows that the system's performance is directly tied to the pixel workload, a hallmark of a GPU-bound scenario.

Measured FPS Breakdown

This section details the exact measured average frame rates for each resolution and settings combination. The data is derived directly from the measuredFps array.

1920x1080:

• Low: 125 FPS average. This is the only configuration that achieves a high refresh rate experience.
• Medium: 88 FPS average, with a minimum of 75 FPS and a maximum of 102 FPS. This is a playable range for most users.
• High: 62 FPS average. This is a solid, smooth frame rate for a simulation title.
• Ultra: 59 FPS average. The difference between High and Ultra is minimal, only 3 FPS.

2560x1440:

• Low: 79 FPS average. This is still a very playable frame rate.
• Medium: 56 FPS average, with a minimum of 47 FPS and a maximum of 64 FPS. This dips below 60 FPS but remains acceptable.
• High: 39 FPS average. This is a significant drop from 1080p and is approaching the edge of playability.
• Ultra: 38 FPS average. Performance is nearly identical to High, indicating the GPU is overwhelmed.

3840x2160:

• Low: 41 FPS average. This is the only 4K setting that approaches playability.
• Medium: 29 FPS average, with a minimum of 25 FPS and a maximum of 34 FPS. This is generally too slow for a smooth experience.
• High: 21 FPS average. This is not playable.
• Ultra: 20 FPS average. This is a slideshow and not a viable option.

The data shows that the system is capable of a good experience at 1080p and a passable one at 1440p, but it struggles significantly at 4K.

How This Combo Ranks

The AMD Ryzen 7 5700 and Intel Arc B390 combination is ranked 2650th out of 3002 tested combos in Pc Building Simulator. This places it in the bottom 12% of all configurations, confirming its status as a low-performance pairing for this game.

This rank is heavily influenced by the GPU's poor standing. The Arc B390's 9th percentile ranking among all GPUs is a major drag on the combo's overall performance. The CPU, by contrast, is a top-tier performer. The Ryzen 7 5700 has a 78th percentile ranking among all CPUs, with an average benchmark score of 25517. This is a stark contrast between the two components.

In the context of the combo's rank, the data suggests that the CPU is not contributing to the low ranking. The bottleneck is almost entirely the GPU. If this processor were paired with a more capable graphics card, the combo's rank would likely be significantly higher. The current rank is a direct reflection of the GPU's inability to keep up with the demands of the game at higher resolutions and settings. This is a case where a powerful CPU is severely held back by a weak GPU, resulting in a disappointing overall system performance.

CPU Role

The AMD Ryzen 7 5700 provides the processing foundation for this system, and its role in Pc Building Simulator is to ensure that the CPU is never the limiting factor. This processor is a powerhouse, built on the Zen 3 architecture with 8 cores and 16 threads. It has a base clock of 3.70 GHz and a boost clock of 4.60 GHz.

The CPU's benchmark scores demonstrate its capability. It achieves a Cinebench R23 multicore score of 20655 and a single-core score of 2916. Its 3DMark 16-thread score is 6628, and its Geekbench multicore score is 9959. These figures place it well above the performance necessary for a simulation game like Pc Building Simulator, which typically relies more on single-thread performance for game logic but can benefit from multiple cores for background simulation tasks.

The CPU's memory support is also relevant. It supports dual-channel DDR4 memory with a theoretical bandwidth of 51.2 GB/s. This is the memory bandwidth that the Intel Arc B390 will use for its "System Shared" memory. While this is not a fast as dedicated GDDR6, it is sufficient for the CPU's own tasks.

Given that the GPU is the bottleneck in all measured scenarios, the CPU's role is to provide a stable platform without introducing stutters or frame drops. The data shows that it succeeds admirably. The CPU's high performance ensures that the frame rates are limited solely by the GPU's rendering capabilities, not by the processor's ability to feed it data or execute game code.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend entirely on the user's target resolution and desired frame rate.

For 1920x1080: The best experience is achieved at High settings, which delivers a 62 FPS average. This provides a good balance between visual quality and smoothness. While Low settings offer 125 FPS, the visual trade-off is often not worth it in a simulation game where detail matters. Medium settings at 88 FPS are also excellent, but High offers a more immersive experience without dropping below 60 FPS. Ultra settings at 59 FPS are not worth the marginal visual improvement over High.

For 2560x1440: The recommended setting is Low, which yields a 79 FPS average. This is the only 1440p setting that maintains a frame rate above 60 FPS. Medium settings at 56 FPS is a viable alternative for those who prioritize visual fidelity over a perfectly smooth frame rate, but it will result in occasional dips below 60 FPS. High and Ultra settings are not recommended, as they average below 40 FPS, which is a poor experience for a simulation game.

For 3840x2160: The only viable option is Low, which produces a 41 FPS average. This is below the 60 FPS threshold but is technically playable. Medium settings at 29 FPS and High/Ultra at 21/20 FPS are not recommended for a satisfactory experience. Users with a 4K monitor should accept the visual compromises of Low settings or consider lowering the resolution to 1440p for a much better frame rate.

In summary, the data suggests that 1080p High is the "best experience" for this combination, offering a solid 60+ FPS with good image quality. For 1440p, users must drop to Low to achieve smooth gameplay. 4K is not a practical resolution for this hardware, with even Low settings failing to hit 60 FPS.
