Pc Building Simulator

The Intel Core i5-12400 paired with the Intel Arc B580 presents a distinct performance profile in Pc Building Simulator, a simulation title that scales significantly with graphics settings. The measured data shows a system capable of high refresh rates at mainstream resolutions, but one that becomes heavily constrained at 4K when visual fidelity is prioritized. This analysis walks through the measured FPS data to understand where the bottleneck lies and how to best configure the game.

Resolution Scaling

The frame rate drop from 1080p to 4K is dramatic and reveals the GPU as the primary limiting factor at higher resolutions. At Low settings, the system delivers 214.8 FPS at 1920x1080, which falls to 138.9 FPS at 2560x1440, and then drops to 72.2 FPS at 3840x2160. That represents a 66% reduction in performance from 1080p to 4K, indicating the rendering load on the Arc B580 is scaling steeply with pixel count.

The scaling pattern becomes even more telling at Ultra settings. The system produces 103.3 FPS at 1080p, which is still smooth, but this falls to 62.4 FPS at 1440p and then to just 31.8 FPS at 4K. The difference between 1440p and 4K is nearly a 49% drop in frame rate, underscoring that the Arc B580's 12 GB of GDDR6 memory and 456.0 GB/s bandwidth are being saturated by the 4K Ultra workload. The data shows that 4K Ultra is simply not viable for smooth gameplay, while 4K Low remains playable but far from ideal.

At High settings, the pattern persists. The system achieves 109.4 FPS at 1080p, 65.6 FPS at 1440p, and 34.9 FPS at 4K. The ratio of performance between 1080p and 1440p is roughly 1.67x, while the ratio between 1440p and 4K is about 1.88x. This non-linear scaling confirms that the GPU's processing power, specifically its 13.67 TFLOPS FP32 throughput, is the limiting component as resolution increases. The CPU’s role is minimal here, as Pc Building Simulator is not a multi-threaded stress test.

Settings Recommendations

The measured rows provide a clear hierarchy of settings for each resolution. For 1920x1080, the Ultra preset at 103.3 FPS is the best experience, as it delivers a frame rate well above the 60 FPS threshold while maximizing visual quality. The step from High to Ultra only costs 6.1 FPS, from 109.4 to 103.3, making the upgrade worthwhile. Medium at 154 FPS is smoother, but the visual fidelity loss is unnecessary given the headroom.

At 2560x1440, the data suggests High settings as the optimal balance. It delivers 65.6 FPS, which is just above the 60 FPS target, while Ultra drops to 62.4 FPS. Both are playable, but High provides a slightly safer margin for frame time consistency. Medium at 98.3 FPS is an option for those seeking higher refresh rates, but the GPU is capable of handling the High preset without significant compromise. Low at 138.9 FPS is excessive unless the user prioritizes maximum frame rate above all else.

For 3840x2160, the situation is different. Ultra at 31.8 FPS is unplayable, and High at 34.9 FPS is also below the playable threshold. Medium at 50.8 FPS is borderline, offering a playable experience for less demanding users. The only preset that achieves a smooth frame rate is Low at 72.2 FPS. The recommendation is to use Low settings at 4K, as it is the only measured configuration that allows for fluid gameplay. Alternatively, users should consider lowering the resolution to 1440p to use higher settings.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its benchmark scores indicate a solid mid-range performer. In Cinebench R23, it scores 15935 multicore and 2249 single-core, placing it in the 77th percentile against all CPUs. The data shows that this CPU is not a bottleneck in Pc Building Simulator, as the frame rate scaling is almost entirely tied to resolution and GPU load.

The nearest rivals to this CPU include the Intel Core i7-9700 with an average score of 19831 and a delta of 0.1%, and the Intel Core i7-8700 with a score of 19894 and a delta of -0.2%. These differences are negligible, confirming that the i5-12400 is competitive with older i7 parts. For this simulation game, the CPU's 18 MB of shared L3 cache and dual-channel memory support are sufficient, as the game does not appear to stress multi-threaded workloads beyond what the 12 threads provide.

The measured FPS at 1080p Low of 214.8 FPS shows that the CPU can feed the GPU at very high frame rates. This suggests that even at 4K Low, the CPU is not the limiting factor, as the drop to 72.2 FPS is solely due to GPU rendering load. The CPU's single-thread performance, as evidenced by the Cinebench R23 score of 2249, is adequate for the game's simulation logic, which does not scale with resolution.

FAQ

Q: What is the best settings preset for 1920x1080?

A: The Ultra preset delivers 103.3 FPS, which is above the 60 FPS target and offers the highest visual quality. High is also viable at 109.4 FPS, but Ultra provides a better experience for a minor performance cost.

Q: Is the game playable at 4K with this hardware?

A: At Low settings, the game runs at 72.2 FPS, which is playable. Medium at 50.8 FPS is borderline, while High and Ultra at 34.9 and 31.8 FPS respectively are not smooth enough for most users.

Q: How does the Intel Arc B580 compare to the NVIDIA GeForce RTX 4060?

A: The Arc B580 has an average benchmark score of 23021, while the RTX 4060 scores 23181, a delta of -0.7%. This indicates they are nearly identical in performance, with the RTX 4060 having a marginal edge.

Q: Does the CPU limit performance at 1080p?

A: No. The 214.8 FPS at 1080p Low indicates the CPU can handle the game easily. The bottleneck shifts to the GPU as resolution increases, but at 1080p, the CPU is not a constraint.

Q: What is the frame rate difference between High and Ultra at 1440p?

A: High delivers 65.6 FPS, while Ultra delivers 62.4 FPS. The difference is only 3.2 FPS, making High the more efficient choice for a stable frame rate.

Q: How much VRAM does the GPU have, and is it sufficient?

A: The Intel Arc B580 has 12 GB of GDDR6 memory. The data shows no signs of VRAM limitation even at 4K Ultra, as the frame rate drops are consistent with compute load rather than memory capacity issues.

GPU Role

The Intel Arc B580 is built on the Xe2-HPG architecture with a 5 nm process and 19,600 million transistors. It features 2560 shading units, 160 TMUs, and 80 ROPs, with a base and boost clock of 2670 MHz. The GPU's 12 GB of GDDR6 memory runs at 19 Gbps effective, providing 456.0 GB/s of bandwidth across a 192-bit bus. Its FP32 performance is 13.67 TFLOPS, and it scores 15748 in Passmark G3D, placing it in the 66th percentile against all GPUs.

The GPU's nearest rival is the AMD Radeon 760M, with a delta of 0.1%, and the NVIDIA GeForce RTX 4060, with a delta of -0.7%. These close scores suggest the Arc B580 is a competent 1080p and 1440p card, but its performance at 4K is limited by its compute throughput. The measured FPS data confirms this: at 4K Ultra, the system only manages 31.8 FPS, which is a 69% drop from the 1080p Ultra score of 103.3 FPS.

The GPU's memory bandwidth of 456.0 GB/s is a key factor in its scaling behavior. At 1080p, the frame rates are high, but as resolution increases, the bandwidth and pixel fill rate become saturated. The texture rate of 427.2 GTexel/s and pixel rate of 213.6 GPixel/s are adequate for 1440p, but not for 4K at high settings. The data shows that the Arc B580 is best suited for 1080p and 1440p gaming, where it can maintain high frame rates, while 4K requires significant settings compromises.

Measured FPS Breakdown

At 1920x1080, the system delivers 214.8 FPS on Low, 154 FPS on Medium, 109.4 FPS on High, and 103.3 FPS on Ultra. The scaling from Low to Ultra shows a linear progression, with Ultra being 52% slower than Low. This indicates the GPU is the primary driver of performance, with no CPU bottleneck evident.

At 2560x1440, the scores are 138.9 FPS on Low, 98.3 FPS on Medium, 65.6 FPS on High, and 62.4 FPS on Ultra. The drop from Low to Medium is 40.6 FPS, while the drop from Medium to High is 32.7 FPS. The difference between High and Ultra is only 3.2 FPS, suggesting diminishing returns at the highest preset.

At 3840x2160, the results are 72.2 FPS on Low, 50.8 FPS on Medium, 34.9 FPS on High, and 31.8 FPS on Ultra. The scaling here is steep, with Ultra being 56% slower than Low. The gap between High and Ultra is 3.1 FPS, which is similar to the 1440p gap, but the absolute frame rates are below playable thresholds for most users. The data clearly shows that 4K requires Low settings for smooth gameplay, while 1440p can handle High, and 1080p can run Ultra without issue.
