Pc Building Simulator

Pc Building Simulator presents an unusual hardware challenge: it is a simulation about assembling PCs, yet its own performance profile is heavily skewed by the components being simulated. The AMD Ryzen 5 7500X3D and Intel Arc B390 combination produces a playable but ultimately limited experience, with the data indicating a profound bottleneck that shifts depending on resolution and settings. The benchmark results show this pairing ranks in the bottom 12% of all tested combinations, a position driven almost entirely by the graphics solution rather than the processor.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 7500X3D is a 6-core, 12-thread processor from the 7000 series, built on the Raphael (Zen 4) architecture using a 5 nm process. It operates with a base clock of 4.00 GHz and a boost clock of 4.50 GHz, and it carries a 65 W TDP. The chip features a substantial 96 MB of shared L3 cache, which is a hallmark of the X3D line and typically benefits gaming workloads that rely on large datasets. Its memory support is DDR5 via a dual-channel bus, yielding a theoretical bandwidth of 83.2 GB/s.

In the context of Pc Building Simulator, the CPU’s role is secondary to the GPU across most settings, but it is not irrelevant. Looking at the 1080p results, the processor clearly has enough headroom to feed the graphics card. The jump from Low to Ultra settings at 1920x1080 shows a drop from 125 FPS to 59 FPS, which is a classic sign of increasing GPU load rather than CPU limitation. The CPU’s single-thread score of 3494 in Passmark and a multithread score of 25047 suggest it is more than capable of handling the simulation’s logic, which involves tracking component stats and build configurations rather than complex physics.

The 7500X3D sits in the 89th percentile of all CPUs, indicating it is a high-end part. Its nearest rivals in average benchmark score are the Intel Core Ultra X9 388H (0.2% lower), the Intel Core i9-13950HX (0.5% lower), and the AMD Ryzen AI Max 385 (0.6% lower). It is also 0.7% ahead of the Intel Core i5-14600. These margins are tiny, meaning the 7500X3D is effectively performance-equivalent to those chips in general compute tasks. However, in this game, the CPU is rarely the limiting factor. Evidence for this is the relatively small FPS gap between 1080p Low (125 FPS) and 1440p Low (79 FPS), which is a 46 FPS drop that points to the GPU struggling with more pixels, not the CPU running out of steam.

The processor’s L3 cache advantage does not translate into a measurable benefit here because Pc Building Simulator’s frame rate is capped by the GPU’s ability to render the interface and 3D models. At 4K Ultra, the system drops to 20 FPS, which is far below what the CPU could theoretically produce. The data suggests that even at lower resolutions, the CPU is waiting on the GPU. The 1080p Ultra result of 59 FPS versus the 1080p High result of 62 FPS shows that the CPU is not the bottleneck; if it were, the frame rate would remain nearly constant regardless of settings. Instead, the FPS scales with graphical load, confirming the CPU has ample reserves.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B390 is the primary constraint in this configuration. It is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, built on Intel’s 3 nm process. Its clocks are listed as a base of 300 MHz and a boost of 2500 MHz. Critically, its memory is marked as "System Shared," meaning it has no dedicated VRAM and instead borrows from the system’s DDR5 memory. The memory bandwidth is likewise "System Dependent," which ties its performance directly to the CPU’s memory controller.

This shared memory architecture is the root cause of the poor performance. The GPU’s benchmark score in 3DMark Steel Nomad (DX12) is 1482, which places it in the 9th percentile of all GPUs. Its nearest rivals are the NVIDIA GeForce GT 520MX (1.3% higher), the NVIDIA GeForce 800M (1.5% higher), and the NVIDIA GeForce GT 625 OEM (2.5% higher). The Arc B390 is also 2.7% faster than the NVIDIA GeForce GT 710. These are all low-end or legacy parts, indicating that the B390 is not designed for gaming at competitive frame rates.

In Pc Building Simulator, the GPU’s lack of dedicated VRAM becomes a severe issue at higher resolutions. The measured FPS shows a stark collapse as resolution increases. At 1080p Low, the system achieves 125 FPS, which is acceptable. But at 4K Low, it drops to 41 FPS, a 67% reduction. This is not a typical scaling curve; it is a sign that the GPU is forced to use system memory for framebuffer operations, and the bandwidth constraints become crippling. The GPU has 1536 shading units, 48 TMUs, and 24 ROPs, with a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. These raw specs are not terrible on paper, but the memory bottleneck negates them.

The data shows that the Arc B390 is the limiting component in all scenarios except perhaps the absolute lowest settings at 1080p, where the CPU might briefly become relevant. The 4K Medium result of 29 FPS (with a minimum of 25 FPS and maximum of 34 FPS) illustrates that even moderate settings at high resolution are unplayable. The GPU’s 80 W TDP is low, confirming its integrated nature, but that does not excuse the performance. The system shared memory means that the frame rate is also dependent on the CPU’s memory bandwidth of 83.2 GB/s, which is insufficient for a modern game at 4K.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The resolution scaling data is the most revealing aspect of this benchmark. From 1080p to 4K, the average FPS drops are dramatic and consistent across settings, pointing squarely at the GPU as the sole bottleneck. At Low settings, the system goes from 125 FPS at 1080p to 79 FPS at 1440p, and then to 41 FPS at 4K. That is a 36.8% drop from 1080p to 1440p, and a further 48.1% drop from 1440p to 4K. This is not linear scaling; it is exponential degradation, which is typical of a GPU that is overwhelmed by pixel count.

At High settings, the drop is from 62 FPS at 1080p to 39 FPS at 1440p (a 37.1% reduction) and then to 21 FPS at 4K (a 46.2% reduction from 1440p). The pattern repeats at Medium settings: 88 FPS at 1080p, 56 FPS at 1440p, and 29 FPS at 4K. The Ultra settings show the same trend: 59 FPS at 1080p, 38 FPS at 1440p, and 20 FPS at 4K. The relative consistency of these percentage drops across different settings is a clear indicator that the limiting factor is the GPU’s inability to process pixels, not the CPU or any other system component.

The fact that the 1080p Low result (125 FPS) is the only truly playable frame rate in the dataset suggests that the GPU can handle the game only when the resolution is low enough to fit within its shared memory bandwidth. At 1440p Low, the 79 FPS is borderline acceptable, but the 4K results are all below 41 FPS, which is a poor experience for any game. This scaling behavior confirms that the Arc B390 is the primary bottleneck. If the CPU were the limiting factor, the FPS would not drop so precipitously as resolution increases; instead, the frame rate would remain relatively flat because the CPU workload does not change with resolution. The data shows the opposite, so the GPU is clearly the constraint.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the AMD Ryzen 5 7500X3D and the Intel Arc B390 ranks 2650 out of 3002 tested combos in Pc Building Simulator. That places it in the bottom 11.7% of all configurations. This ranking is not surprising given the GPU’s low percentile (9th), but it is interesting to note that the CPU’s high percentile (89th) does not rescue the overall standing. The combo rank is likely weighted heavily by the GPU’s performance, since the game’s frame rates are so dependent on the graphics solution.

The CPU’s position relative to its rivals does not help the combo rank. The 7500X3D is within 1% of the Intel Core Ultra X9 388H, Intel Core i9-13950HX, and AMD Ryzen AI Max 385 in average benchmark score, but those chips are also likely paired with better GPUs in the database, pushing them higher in the combo rankings. The data shows that the CPU is not the issue; the GPU is. The Arc B390’s nearest rivals are all ancient or low-end NVIDIA parts, and the B390 is only slightly faster than them. This means that in the context of this game, the combo is effectively handicapped by a graphics solution that is only marginally better than a GeForce GT 710.

The rank of 2650 out of 3002 indicates that this combo is not viable for a smooth gaming experience at any resolution above 1080p Low. The data suggests that users would be better served by pairing the 7500X3D with any discrete GPU, as the CPU has significant headroom. The combo rank is a direct reflection of the GPU’s limitations, and the CPU’s strong benchmark scores are wasted in this configuration.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a complete picture of what to expect from this combo. At 1920x1080, the results are as follows: Low settings produce an average of 125 FPS. Medium settings yield 88 FPS, with a minimum of 75 FPS and a maximum of 102 FPS. High settings drop to 62 FPS, and Ultra settings produce 59 FPS. This is the only resolution where the game is consistently playable, though Ultra just barely crosses the 60 FPS threshold, falling short at 59 FPS.

At 2560x1440, the performance degrades significantly. Low settings average 79 FPS, which is still decent. Medium settings drop to 56 FPS, with a minimum of 47 FPS and a maximum of 64 FPS. High settings average 39 FPS, and Ultra settings average 38 FPS. The 1440p results show that only Low settings are reliably smooth, while Medium and above will result in noticeable stutter and frame pacing issues.

At 3840x2160, the system struggles to maintain playable frame rates. Low settings average 41 FPS, which is below the 60 FPS target. Medium settings drop to 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. None of the 4K results are playable for a smooth experience, and even the Low setting at 41 FPS will feel sluggish. The data clearly shows that this combo is only suitable for 1080p gaming, and even then, only at Low or Medium settings for a consistent frame rate.
