Pc Building Simulator

The AMD Ryzen 9 5950X paired with the Intel Arc B390 produces a highly unusual performance profile in Pc Building Simulator. The data shows a configuration that is severely limited by its graphics component, yet the CPU's raw capability ensures that even the most demanding settings remain playable at lower resolutions. This analysis breaks down the measured FPS across resolutions and settings to explain what this combo does well and where it falls short.

Resolution Scaling

The measured FPS data reveals a clear and dramatic dependency on resolution, which is the hallmark of a GPU-bound scenario. At 1920x1080, the combo delivers its best performance, with an average of 125 FPS on Low settings. As resolution increases to 2560x1440, that Low setting average drops to 79 FPS, a 37% reduction. Moving to 3840x2160, the Low setting average falls further to 41 FPS, which is 48% lower than the 1440p result and 67% lower than the 1080p result.

This scaling pattern is consistent across all settings presets. On High settings, the frame rate drops from 62 FPS at 1080p to 39 FPS at 1440p and then to 21 FPS at 4K. The gap between 1440p and 4K is particularly steep, with High settings losing 18 FPS (46%) when moving up that resolution step. Medium settings follow the same trajectory: 88 FPS at 1080p, 56 FPS at 1440p, and 29 FPS at 4K. The Ultra preset shows the most severe scaling, going from 59 FPS at 1080p to 38 FPS at 1440p and finally to just 20 FPS at 4K.

The data strongly indicates that the Intel Arc B390 is the limiting component in this pairing. The Ryzen 9 5950X has 16 cores and 32 threads, a 3.40 GHz base clock, and a 4.90 GHz boost clock, which is more than sufficient for a simulation title. The consistent halving of frame rates as resolution quadruples the pixel count points directly at the GPU's fill rate and shading capacity being overwhelmed. The Arc B390's boost clock of 2500 MHz and 7.680 TFLOPS of FP32 performance are simply not enough to maintain high frame rates at higher resolutions.

For practical use, this means the combo is only suitable for 1080p gaming if you want high frame rates. At 1440p, the performance is acceptable for slower-paced simulation gameplay, but you will need to use lower presets. At 4K, the frame rates are too low for a smooth experience, even on Low settings, which only managed 41 FPS. The 4K Ultra setting, at 20 FPS, is effectively unplayable.

How This Combo Ranks

In the grand scheme of tested hardware combinations, this pairing ranks near the bottom. The comboRankInGame places it at 2650 out of 3002 tested combos, meaning it outperforms only about 12% of all configurations tested in Pc Building Simulator. This is a poor showing, placing it in the bottom percentile of all possible pairings.

This low rank is almost entirely attributable to the GPU. The Ryzen 9 5950X is a high-end processor that sits in the 91st percentile of all CPUs in the database. Its average benchmark score of 51947 is nearly identical to its nearest rivals, including the Intel Core Ultra 5 235HX (52073, a 0.2% difference) and the AMD EPYC 8124P (52121, a 0.3% difference). This indicates the CPU is performing exactly as expected for its class.

The Intel Arc B390, however, is a different story. It sits in the 9th percentile of all GPUs, and its average benchmark score of 1482 places it in direct competition with very old, entry-level discrete cards. Its nearest rivals are the NVIDIA GeForce GT 520MX (1463, 1.3% faster), the NVIDIA GeForce 800M (1460, 1.5% faster), and the NVIDIA GeForce GT 625 OEM (1446, 2.5% faster). These are all legacy parts from over a decade ago, which underscores how underpowered the B390 is for modern gaming workloads.

The data makes it clear that the CPU is not the bottleneck. The 5950X is a top-tier part that has the processing power to push well beyond the frame rates shown here. The GPU is the sole reason this combo ranks at 2650 out of 3002. When building a system for Pc Building Simulator, this pairing demonstrates that a powerful CPU cannot compensate for a weak GPU in a graphically intensive title.

GPU Role

The Intel Arc B390 is the primary bottleneck in this configuration, and its specifications confirm why. It is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, which is designed for low-power mobile parts, not desktop gaming. Its memory is "System Shared," meaning it uses a portion of the system's main RAM instead of dedicated VRAM. This is a critical limitation, as the memory bandwidth is "System Dependent," which is typically far lower than what a dedicated graphics card offers.

The GPU's clock speeds do not help its cause. It has a base clock of 300 MHz and a boost clock of 2500 MHz. While the boost clock is respectable, the low base clock and the shared memory architecture severely hamper sustained performance. The shading units count is 1536, with 48 TMUs and 24 ROPs. This configuration results in a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. These figures are simply too low to handle the demands of rendering at high resolutions and detail levels.

The GPU also has 12 ray tracing cores, but the raw compute performance of 7.680 TFLOPS FP32 is insufficient to do anything meaningful with them in this game. The benchmark data for the GPU is sparse, with only a single 3DMark Steel Nomad DX12 score of 1482. This low score is consistent with its performance percentile of 9, confirming it is a very low-end part.

In Pc Building Simulator, the GPU's limitations manifest as the severe frame rate drops seen when increasing resolution. At 1080p, the GPU can just barely keep up, but as pixel count increases, its fill rate and memory bandwidth become the limiting factor. The fact that the 4K Low setting (41 FPS) is slower than the 1080p Ultra setting (59 FPS) shows that the GPU is completely saturated at higher resolutions. There is no CPU bottleneck here; the Ryzen 9 5950X is more than capable of feeding the GPU with data. The GPU simply cannot render fast enough.

A: The Ultra and High presets should be avoided at 1440p. They average 38 FPS and 39 FPS, respectively, which is borderline playable but not smooth. The Medium preset, at 56 FPS, is the highest quality option that maintains a reasonable frame rate.

Q: Is this combo ranked well among all tested systems for this game?

A: No. It ranks 2650 out of 3002 total combinations. This places it in the bottom 12% of all tested hardware pairings, indicating a poor overall performance level for this specific game.

Settings Recommendations

Given the data, the optimal settings depend heavily on the target resolution. For a 1920x1080 display, the High preset at 62 FPS averages is a good balance of visual quality and smoothness. However, if you prefer maximum visual fidelity, the Ultra preset at 59 FPS is also playable. The Low preset at 125 FPS is unnecessary unless you have a very high refresh rate monitor and want to maximize frame pacing.

At 2560x1440, the Medium preset represents the best experience. It averages 56 FPS, which is smooth enough for a simulation game. The High and Ultra presets, at 39 FPS and 38 FPS respectively, will feel stuttery and are not recommended for a comfortable experience. The Low preset at 79 FPS is the smoothest option, but the visual quality reduction is significant.

For 3840x2160, the data suggests this combo is not suitable for a high-quality experience. The Low preset averages 41 FPS, which is playable but far from ideal. The Medium preset drops to 29 FPS, and the High and Ultra presets at 21 FPS and 20 FPS respectively are too low for any practical use. If you must play at 4K, use the Low preset and accept the low frame rate. The measured minimum FPS of 25 on Medium and 47 on 1440p Medium shows that frame pacing can be inconsistent, further reducing the playability of higher settings.

The best overall experience is 1920x1080 with the High preset. It offers a solid 62 FPS average and good visual fidelity. If you need higher frame rates, dropping to Low at 1080p doubles the frame rate to 125 FPS. For 1440p users, Medium is the only viable preset that balances quality and performance. Avoid Ultra at any resolution above 1080p.

CPU Role

The AMD Ryzen 9 5950X is a high-end desktop processor that is completely overqualified for the task this combo is given. It features 16 cores and 32 threads, based on the Zen 3 architecture (Vermeer) on a 7 nm process. Its base clock of 3.40 GHz and boost clock of 4.90 GHz allow for strong single-threaded performance, evidenced by a Cinebench R23 single-core score of 1614 and a Geekbench single-core score of 2083.

The CPU's multi-threaded performance is where it truly excels. It scores 26017 in Cinebench R23 multi-core, 4324 in Cinebench R15 multi-core, and 15233 in Geekbench multi-core. In Passmark tests, it shows extreme strength in integer math (185520) and floating-point math (100280). This processing power is far beyond what Pc Building Simulator requires for its simulation logic.

The data shows that the CPU is not the constraint. Its 91st percentile ranking and average benchmark score of 51947 put it on par with the best processors available. The nearest rivals, such as the Intel Core Ultra 5 235HX and Intel Core i9-13900F, show less than a 1% difference in average score, meaning the 5950X is in the top tier of consumer CPUs.

In this specific game, the CPU's role is to run the simulation and feed the GPU with draw calls and geometry. With 32 threads, it can handle any amount of background tasks or complex in-game calculations that Pc Building Simulator might throw at it. However, since the GPU is so weak, the CPU spends most of its time waiting. The measured frame rates are entirely dictated by the Arc B390's rendering speed, not the CPU's processing capability.

This pairing is a textbook example of an unbalanced system. The Ryzen 9 5950X is a capable processor that could easily drive a much more powerful GPU to achieve frame rates several times higher than what the Arc B390 can produce. If the goal is to play Pc Building Simulator, the CPU is not the component to upgrade; it is the GPU that needs to be replaced to improve performance. The CPU's 64 MB of L3 cache and dual-channel DDR4 memory support are excellent features, but they are wasted when paired with a GPU that cannot utilize the data fast enough.
