Pc Building Simulator

Intel Core i5-12400 paired with the Intel Arc B370 presents a fascinating case study in Pc Building Simulator, where the benchmark data reveals a system that is fundamentally constrained by its graphics solution. The 6-core/12-thread Alder Lake processor demonstrates ample computational headroom, while the integrated-class Arc B370 GPU, based on the Xe3-LPG architecture, consistently becomes the limiting factor across all tested resolutions and settings. This analysis examines the measured FPS data to provide a clear picture of what builders can expect from this combination.

Resolution Scaling

The resolution scaling behavior in Pc Building Simulator is telling, with the Arc B370 showing severe performance degradation as pixel count increases. At 1080p with Low settings, the system achieves a highly playable 113 FPS average, but this drops to 80 FPS at Medium, 56 FPS at High, and 54 FPS at Ultra. The step from 1080p to 1440p is punishing: Low settings fall from 113 FPS to 71 FPS (a 37% reduction), while High settings drop from 56 FPS to 36 FPS (a 36% reduction). This scaling pattern indicates that the GPU is already near its throughput ceiling even at 1080p, and the additional pixel workload at 1440p directly translates to proportional FPS losses.

Moving to 4K reveals the true extent of the bottleneck. At 3840x2160, even Low settings only manage 37 FPS, which represents a 67% collapse from the 1080p Low result. The Medium preset at 4K produces 26 FPS, while High and Ultra fall to 19 FPS and 18 FPS respectively. The 4K High result is particularly revealing—it is only 1 FPS better than the 4K Ultra result, suggesting that the GPU has hit a hard computational wall where additional settings changes yield negligible differences. The data strongly indicates that this combination is only suitable for 1080p gaming, with 1440p being borderline playable only at Low settings, and 4K being effectively unplayable for any smooth experience.

The frame time consistency also degrades with resolution. At 1080p Medium, the measured range spans 68 to 92 FPS, a 24 FPS variance that becomes more pronounced at 1440p Medium, where the range extends from 43 to 58 FPS. This growing spread at higher resolutions points to the system struggling to maintain consistent frame pacing under increased load. The 4K Medium data shows a 22 to 30 FPS range, which means the experience can fluctuate by nearly 40% during gameplay. Such variance at playable frame rates is acceptable, but at 4K's sub-30 FPS levels, it compounds the perceived stutter.

How This Combo Ranks

Within the benchmark database, this combination ranks 2761st out of 3002 tested combos for Pc Building Simulator, placing it in the bottom 8% of all configurations. This low ranking is almost entirely attributable to the Arc B370's performance class. The GPU's percentile ranking against all graphics cards sits at just 5%, meaning it outperforms only 5% of the GPUs in the database. In contrast, the Core i5-12400 holds a 72nd percentile ranking among all CPUs, indicating the processor is well above average while the graphics solution is firmly in the entry-level segment.

The disparity between CPU and GPU capabilities creates an interesting dynamic. The combo's rank of 2761 suggests that most other tested combinations—even those with weaker processors—achieve higher FPS in this game because they pair them with more capable graphics hardware. The data shows that Pc Building Simulator, despite being a simulation title, is heavily dependent on GPU performance for its rendered scenes. The CPU's nearest rivals in aggregate benchmark scores include the AMD EPYC 7643 (0.1% slower), Intel Core i7-1355U (0.3% slower), and AMD Ryzen AI 5 330 (0.7% slower), while the Intel Core i3-14100F is 0.9% faster. These margins are negligible in real-world gaming, confirming that the processor is not the differentiator here.

When examining the GPU's nearest rivals, the picture becomes clearer. The Arc B370's average benchmark score of 1184 places it near the ATI Mobility Radeon HD 5570 (0.2% faster), ATI Radeon HD 5770 (0.5% faster), and AMD Radeon HD 7650M (0.7% faster), with the AMD FirePro M2000 being 1.4% slower. These are all legacy or low-end mobile parts, which contextualizes why the combo ranks so poorly. The combination's rank reflects a GPU that was never designed for demanding gaming workloads, despite the CPU being more than capable.

GPU Role

The Intel Arc B370 is an integrated graphics processor built on the 3nm Panther Lake process with the Xe3-LPG architecture. Its specifications reveal its entry-level positioning: 1280 shading units, 40 texture mapping units, and 20 raster operations pipelines, alongside 10 ray tracing cores. The GPU operates at a 300 MHz base clock and boosts to 2400 MHz, delivering 6.144 TFLOPS of FP32 performance and 12.29 TFLOPS of FP16 performance. The pixel rate is 48.00 GPixel/s and the texture rate is 96.00 GTexel/s, figures that directly explain the resolution scaling observed in the measured FPS data.

Critically, the Arc B370 uses System Shared memory, meaning its VRAM allocation and bandwidth are system-dependent. There is no dedicated memory bus or fixed bandwidth figure—it borrows from the main system RAM, which is typically slower than dedicated GDDR memory. This shared memory architecture is a primary reason why the GPU struggles at higher resolutions, as the increased memory pressure at 4K cannot be met with sufficient bandwidth. The GPU's TDP is a mere 25 W, and it requires no power connectors, confirming its integrated nature.

The measured 3DMark Steel Nomad DX12 score of 1184 places the Arc B370 in the 5th percentile of all GPUs. This single benchmark result aligns perfectly with the in-game performance: a GPU scoring this low in a modern DX12 test will inevitably produce sub-30 FPS at 4K in most games. The 1080p Low result of 113 FPS is actually respectable for such hardware, suggesting that Pc Building Simulator's engine is not overly demanding when settings are minimized. However, the GPU's limited ROP count and texture units become the bottleneck as soon as resolution or quality settings increase.

A: Yes. At Low settings, the average FPS drops from 113 to 71, a 37% reduction. At High settings, it drops from 56 to 36, a 36% reduction, indicating the GPU cannot compensate for the additional pixel workload.

Settings Recommendations

For this specific combination, the benchmark data points to a clear hierarchy of playable settings. At 1080p, the Medium preset at 80 FPS average represents the best balance of visual quality and performance, offering a 24 FPS improvement over High while still providing a smoother experience than the 56 FPS High setting. The Medium preset shows a frame range of 68 to 92 FPS, meaning it rarely dips below 60 FPS, which is acceptable for a simulation game. If absolute smoothness is the priority, Low at 113 FPS is the choice, but the visual downgrade is substantial for only a 33 FPS gain over Medium.

At 1440p, the situation changes dramatically. Low settings at 71 FPS is the only preset that clears the 60 FPS mark, while Medium drops to 50 FPS and High falls to 36 FPS. For 1440p users, Low is the only viable option for competitive or fast-paced play, though the 43 to 58 FPS range on Medium might be acceptable for slower, more methodical simulation gameplay. The 4K resolution should be avoided entirely—all presets produce frame rates below 40 FPS, with the best being Low at 37 FPS, which is still too choppy for a satisfying experience.

The data also reveals diminishing returns when moving from High to Ultra. At 1080p, High averages 56 FPS while Ultra averages 54 FPS—only a 2 FPS difference for the maximum quality settings. At 1440p, the gap is similarly small: 36 FPS at High versus 34 FPS at Ultra. This suggests that Ultra offers negligible visual improvements in this game while consuming the same limited GPU resources. The recommendation is to stick with High as the ceiling, as Ultra provides no meaningful benefit for the performance cost. For the best overall experience, 1080p Medium is the sweet spot, delivering 80 FPS with a quality preset that should look acceptable in a simulation title.

CPU Role

The Intel Core i5-12400 provides robust computational support that far exceeds what the Arc B370 can utilize in this game. This Alder Lake-S processor features 6 cores and 12 threads, with a 2.50 GHz base clock and 4.40 GHz boost clock, operating within a 65 W TDP. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. These specifications translate to strong multi-threaded performance, as evidenced by the Cinebench R23 multi-core score of 15989 and single-core score of 2257, placing it in the 72nd percentile of all CPUs.

The processor's benchmark results show it can handle demanding workloads well beyond gaming. The 3DMark scores of 5873 for 16 threads and 5890 for max threads demonstrate excellent scaling, while the Geekbench multi-core score of 8564 and single-core score of 1848 confirm its balanced architecture. The PassMark multi-thread score of 18747 further validates its capability. In Pc Building Simulator, the CPU's role is likely limited to game logic, simulation calculations, and asset loading, none of which appear to be bottlenecks given that the GPU is clearly the performance limiter.

The i5-12400's nearest rivals in aggregate CPU benchmarks—AMD EPYC 7643, Intel Core i7-1355U, AMD Ryzen AI 5 330, and Intel Core i3-14100F—all score within 0.9% of each other, meaning any of these processors would produce near-identical results in this game when paired with the Arc B370. This underscores that CPU choice has minimal impact on the measured FPS in this configuration. The processor's 10nm process and 163 mm² die size with dual-channel DDR4/DDR5 memory support provide ample bandwidth for the system, but the Arc B370's dependency on shared system memory means that faster RAM could offer marginal improvements in GPU performance, though the measured data does not break down this variable.

The takeaway is that the i5-12400 is overqualified for this GPU pairing in Pc Building Simulator. Its 72nd percentile ranking means it sits above most processors in the database, yet the combo still ranks in the bottom 8% due to GPU limitations. Users with this CPU who upgrade their graphics card in the future would see dramatic FPS improvements without needing to change the processor, as the i5-12400 has substantial headroom for more powerful GPUs.
