Pc Building Simulator

Pc Building Simulator is a simulation title that tasks the system with managing a virtual PC repair and assembly shop, and the benchmark data for the Intel Core i5-12400F paired with the Intel Arc B390 shows a configuration that is heavily constrained by its graphics subsystem. The measured frame rates across resolutions and settings reveal a combo that struggles to maintain smooth gameplay at higher loads, though it can become serviceable when settings are lowered. This analysis breaks down the performance metrics, scaling behavior, and the distinct roles the CPU and GPU play in this specific workload.

How This Combo Ranks

The benchmark database places this specific combination of an Intel Core i5-12400F and an Intel Arc B390 at rank 2650 out of 3002 tested combos in Pc Building Simulator. This places the system in the bottom 12% of all configurations tested, indicating that it is not a high-performance pairing for this game. The ranking reflects a fundamental imbalance where the processor’s capability is largely wasted because the graphics adapter cannot keep up with the demands of the simulation’s rendering.

The GPU is the primary bottleneck, as indicated by its own percentile ranking of 9 among all tested graphics cards. This means the Intel Arc B390 performs better than only about 9% of all GPUs in the database. Its closest rivals in the benchmark charts are legacy or entry-level parts, including the NVIDIA GeForce GT 520MX, which it beats by a delta of 1.3%, and the NVIDIA GeForce 800M, which it leads by 1.5%. It also edges out the NVIDIA GeForce GT 625 OEM by 2.5% and the NVIDIA GeForce GT 710 by 2.7%. These margins are tiny, showing that the Arc B390 is competing at the very bottom of the performance ladder, far from the mid-range or high-end segments. The data shows that for Pc Building Simulator, this GPU is the limiting factor preventing the combo from achieving a higher rank.

In stark contrast, the CPU is a much stronger component. The Intel Core i5-12400F sits in the 73rd percentile of all CPUs, a healthy position that indicates solid mainstream performance. Its average benchmark score of 19039 is virtually identical to its nearest rivals, such as the AMD Ryzen 5 7535HS with a score of 19047 and a deltaPct of 0, and the Intel Core 3 201E with a score of 19056 and a deltaPct of -0.1. It also trades blows with the Intel Core i5-1335U (score 18982, deltaPct 0.3) and the AMD EPYC 7773X (score 18979, deltaPct 0.3). This suggests that the processor is not the reason for the low combo rank; it is a competent mid-tier part that is being held back by a severely underpowered graphics solution. The 2650th place ranking is a direct consequence of the GPU’s position in the 9th percentile, creating a system that can handle the logic of the simulation but struggles to render it.

Settings Recommendations

Given the measured performance data, the optimal experience for this combo in Pc Building Simulator requires significant compromises on visual fidelity. The only settings preset that delivers a consistently playable frame rate is Low. At 1080p with Low settings, the system achieves an average of 125 FPS, which is the highest frame rate recorded for this configuration. This is the only preset at 1080p that breaks the 100 FPS barrier, and it provides a smooth and responsive experience for the simulation’s mechanics. Moving up to Medium at 1080p drops the average to 88 FPS, which is still playable but represents a 30% reduction in performance from the Low preset.

The High preset at 1080p yields an average of 62 FPS. While this is technically playable, it is below the 70 FPS threshold often considered ideal for smooth gameplay and leaves little headroom for complex scenes. The Ultra preset is the worst performer at 1080p, with an average of just 59 FPS and no recorded minimum frame rate, suggesting potential for stutter. For a game that involves managing a workshop and moving components, a stable frame rate is more critical than high-end textures.

At 1440p, the situation becomes more challenging. The Low preset manages an average of 79 FPS, which is still a good experience. However, the Medium preset drops to 56 FPS, and the High preset falls to 39 FPS. The Ultra preset at this resolution averages only 38 FPS. At 4K, even the Low preset only manages an average of 41 FPS, while all other presets fall below the 30 FPS playability threshold. Therefore, the data strongly suggests that users should stick with Low settings for the most consistent performance. If a user has a 1080p display, they might try Medium as a compromise, but Low is the only preset that guarantees a high frame rate across all resolutions tested. The benchmark results show that this combo is not suited for High or Ultra settings in this title.

Resolution Scaling

The frame rate data shows a steep performance cliff as resolution increases, confirming that the Intel Arc B390 is the dominant limiting component. At 1080p with Low settings, the system averages 125 FPS. When moving to 1440p at the same settings, the average FPS drops to 79, a significant reduction of 37%. This indicates that the GPU is already struggling with the increased pixel count at 1440p, despite the low graphical load.

Scaling to 4K at Low settings shows this trend continuing, with the average FPS falling to 41. This is a 67% reduction from the 1080p result. The pattern is consistent across all presets. For example, at Medium settings, the average frame rates are 88 FPS at 1080p, 56 FPS at 1440p, and 29 FPS at 4K. The drop from 1440p to 4K is a 48% reduction in performance. This behavior indicates that the graphics card is hitting its memory bandwidth and processing limits well before the CPU becomes a factor.

The Intel Arc B390’s memory is listed as "System Shared," meaning it relies on the system's main RAM for graphics memory. This architecture is inherently slower than dedicated VRAM and is a major reason for the sharp performance degradation at higher resolutions, where memory demands increase. The GPU's clock speeds, with a base of 300 MHz and a boost of 2500 MHz, are not enough to compensate for the memory bottleneck. The data shows a classic case of a component being overwhelmed by resolution scaling. The CPU, with its 4.40 GHz boost clock, is not the constraint here; the GPU's inability to process the larger frames at 1440p and 4K is what causes the frame rates to plummet. The scaling is not linear, and the performance loss from 1080p to 4K is severe, making high-resolution gameplay impractical for this combo.

FAQ

Q: Is this combo capable of running Pc Building Simulator at 4K resolution?

A: Technically, it can run at 4K, but the results are poor. The highest average frame rate at 4K is 41 FPS, which is achieved only on Low settings. Medium, High, and Ultra presets at this resolution all average below 30 FPS (29, 21, and 20 FPS respectively), which is generally considered unplayable for a smooth experience.

Q: Which component is holding back the performance of this system in this game?

A: The Intel Arc B390 GPU is the clear bottleneck. Its performance percentile is 9, and its average benchmark score of 1482 is only slightly better than very old GPUs like the NVIDIA GeForce GT 520MX. The CPU, on the other hand, is in the 73rd percentile, showing it is far more capable than the graphics card.

Q: How much better is the Low settings preset compared to Ultra at 1080p?

A: At 1920x1080, the Low preset achieves an average of 125 FPS, while the Ultra preset averages just 59 FPS. This means the Low preset is over 110% faster in terms of average frame rate, offering a much smoother experience.

Q: What is the best settings preset for a stable 60 FPS experience at 1440p?

A: The data shows that no preset guarantees a stable 60 FPS at 2560x1440. The Low preset averages 79 FPS, which is above 60, but Medium drops to 56 FPS. Therefore, Low is the only viable option for a high frame rate at this resolution.

Q: How does the Intel Core i5-12400F compare to its closest rivals in synthetic benchmarks?

A: The i5-12400F has an average benchmark score of 19039. This is essentially tied with the AMD Ryzen 5 7535HS (19047), and it is slightly ahead of the Intel Core i5-1335U (18982) and AMD EPYC 7773X (18979). Its performance is consistent with its rivals.

Q: Does the GPU have dedicated video memory?

A: No, the Intel Arc B390 uses "System Shared" memory. This means it uses a portion of the system's main RAM for graphics processing, rather than having its own dedicated VRAM chips on the card.

GPU Role

The Intel Arc B390 is a mobile and integrated-class graphics processor based on the Xe3-LPG architecture. Its performance in Pc Building Simulator is, as the data shows, severely limited. The GPU is ranked in the 9th percentile of all GPUs, which is an extremely low standing. Its average benchmark score from 3DMark Steel Nomad DX12 is 1482, a figure that puts it in direct competition with much older, entry-level discrete GPUs. The nearest rivals include the NVIDIA GeForce GT 520MX, which it outperforms by just 1.3%, and the NVIDIA GeForce GT 710, which it beats by 2.7%. These are not modern gaming parts; they are legacy components, which underscores how weak the Arc B390 is for this workload.

The GPU's specifications support this interpretation. The core clock runs at a base of 300 MHz and can boost up to 2500 MHz, but the key limitation is the memory configuration. With "System Shared" memory and "System Dependent" bandwidth, the GPU is forced to use the system's main memory pool. This creates a significant performance penalty compared to a dedicated graphics card with its own fast VRAM. The high resolution scaling issues seen in the FPS data are a direct result of this memory architecture; as resolution increases, the demand on the shared memory system grows, and the GPU cannot keep up.

The measured FPS results confirm that the GPU is the main obstacle. At 1080p Low, it can manage 125 FPS, but this is its peak performance. At higher settings like High and Ultra, it falls to the 60 FPS range. At 4K, it is simply overwhelmed. The GPU's 1536 shading units and 24 ROPs are not enough to handle the pixel fill rate required at higher resolutions, especially with the memory bandwidth constraints. The data shows that for a simulation game that involves complex UI elements and 3D rendering, this GPU is insufficient for a high-quality experience. It is a component designed for basic tasks, not for gaming at high settings.

CPU Role

The Intel Core i5-12400F is a desktop processor from the Core 12th Gen series, built on the Alder Lake architecture. Unlike the GPU, the CPU is a strong performer. It sits in the 73rd percentile of all CPUs, indicating it is a solid mid-range part. In synthetic benchmarks, it achieves a Cinebench R23 multicore score of 12380 and a single-core score of 1680. Its Passmark multithread score is 19433, and its Geekbench multicore score is 9472. These numbers show a processor with ample computational power for the logic and calculations required by a simulation game like Pc Building Simulator.

The processor has 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This configuration provides strong single-threaded performance, which is often critical for game logic, and decent multi-threaded throughput. The 18 MB of shared L3 cache also helps with data-heavy tasks. In the context of Pc Building Simulator, the CPU is responsible for managing the game’s simulation, part compatibility checks, and customer interactions. The benchmark data suggests that the CPU is not the limiting factor here; it has the headroom to handle the game's processing demands.

The CPU’s position relative to its rivals reinforces this. It is virtually tied with the AMD Ryzen 5 7535HS and the Intel Core 3 201E in average benchmark scores, with deltas of 0% and -0.1% respectively. This means it is a standard mainstream performer. The fact that the overall combo ranks so low (2650 out of 3002) while the CPU ranks in the 73rd percentile points directly to the GPU as the reason for the poor in-game performance. If the CPU were the bottleneck, we would expect to see frame rates that are consistently low across all resolutions. Instead, the FPS drops dramatically as resolution increases, which is a classic sign of a GPU limitation. The CPU is ready to feed frames, but the GPU cannot render them fast enough, especially at higher resolutions.
