Pc Building Simulator

Pc Building Simulator is a simulation title that leans on CPU thread management, GPU memory capacity, and resolution scaling in distinct ways. This analysis covers the Intel Core i5-12400F paired with the NVIDIA GeForce RTX 3050 4 GB, based on measured FPS data at three resolutions and four quality presets. The data shows a combo ranking 1608 out of 1769 tested combinations, which places it in the lower percentile for this specific game, yet the performance patterns reveal exactly where the bottlenecks lie and how to mitigate them.

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

The Intel Core i5-12400F is a 6-core, 12-thread processor from the Alder Lake-S architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its cache layout includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3. This CPU sits at the 77th percentile versus all CPUs, with an average benchmark score of 19221. Its nearest rivals in synthetic testing are the Intel Core i7-8700K (19210, 0.1% slower), Intel Core i5-1335U (19167, 0.3% slower), AMD Ryzen 5 7533HS (19364, 0.7% faster), and AMD EPYC 7773X (18979, 1.3% slower). The i5-12400F effectively trades blows with these chips, showing that its raw compute is competitive, but in Pc Building Simulator, the CPU’s role is more about maintaining a stable floor than pushing extreme frame rates.

In this game, the CPU handles simulation logic—component compatibility checks, thermal calculations, and system boot sequences. The 12 threads are sufficient for these tasks, as evidenced by the 3dmark scores: 909 single-thread, 1699 for 2 threads, 3067 for 4 threads, 4779 for 8 threads, and 5895 for 16 threads. The scaling from 4 to 8 threads is strong (a 55.8% increase), but from 8 to 16 threads it flattens (a 23.4% increase), suggesting the game does not fully utilize all 12 threads. This is typical for simulation titles that rely on a few primary threads. The Cinebench R23 multicore score of 16518 and single-core score of 2332 confirm that the i5-12400F has solid per-core performance, which is more critical here than raw thread count.

The measured FPS data supports this: at 1080p Low, the combo hits 155.5 FPS, which is far above the CPU’s constraint point. Even at 4K Ultra, where the GPU is heavily loaded, the CPU does not become a limiting factor because the frame rate drops to 26.4 FPS—a GPU-bound scenario. The PassMark multithread score of 19433 and physics score of 1202 indicate that the CPU can handle complex simulations, but the game’s engine does not push it to the brink. For practical purposes, the i5-12400F is a capable air-cooled processor for this title, and its 65 W TDP means thermal throttling is unlikely to impact results. The data shows no scenario where the CPU prevents the GPU from reaching its potential, even at the lowest settings where frame rates exceed 150 FPS.

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

The NVIDIA GeForce RTX 3050 4 GB is an Ampere-architecture GPU with a GA107 chip, 2048 shading units, 64 TMUs, and 32 ROPs. It has 16 RT cores and 64 tensor cores, with a base clock of 1545 MHz and a boost clock of 1740 MHz. The memory is 4 GB of GDDR6 on a 128-bit bus, providing 192.0 GB/s of bandwidth. The GPU’s pixel rate is 55.68 GPixel/s, and its texture rate is 111.4 GTexel/s, with FP32 performance at 7.127 TFLOPS. This GPU sits at the 50th percentile versus all GPUs, meaning it is exactly average in the broader market, but its 4 GB VRAM is a critical constraint in modern titles.

In Pc Building Simulator, the GPU’s role is primarily visual—rendering the PC case, components, and workbench. The 4 GB VRAM is sufficient at 1080p, but the data shows a sharp performance cliff at 4K. At 1080p Ultra, the combo achieves 75.9 FPS, but at 4K Ultra, it drops to 26.4 FPS—a 65.2% reduction. This is not just about pixel count; it is about memory pressure. The 4 GB frame buffer is overwhelmed at 4K, causing the GPU to spill into system memory, which tanks performance. The bandwidth of 192.0 GB/s is also a limiting factor, as higher resolutions require more data throughput.

The GPU’s boost clock of 1740 MHz is modest, but the data shows that clock speed is not the primary issue. At 1440p Medium, the combo hits 69.6 FPS, which is playable, but at 4K Medium, it falls to 36.5 FPS—a 47.6% drop. This pattern indicates that the GPU is the dominant bottleneck at higher resolutions, particularly when settings increase. The 90 W TDP and dual-slot design suggest this is an entry-level card, and the 1x 6-pin power connector reinforces that. The data clearly shows that the RTX 3050 4 GB is best suited for 1080p gaming, where it can deliver smooth frame rates, but it struggles at 1440p and becomes nearly unplayable at 4K with demanding settings.

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

The measured FPS data reveals a clear scaling pattern that identifies the GPU as the limiting component. Moving from 1080p to 1440p, the average FPS across all settings drops by roughly 38-41%. For example, at Medium settings, 1080p yields 110.1 FPS, while 1440p yields 69.6 FPS—a 36.8% reduction. At Low settings, 1080p yields 155.5 FPS, while 1440p yields 97.8 FPS—a 37.1% reduction. This is consistent with a GPU-bound scenario, where the CPU has headroom to spare.

The drop from 1440p to 4K is steeper and more revealing. At Medium settings, 1440p yields 69.6 FPS, while 4K yields 36.5 FPS—a 47.6% reduction. At High settings, 1440p yields 50.4 FPS, while 4K yields 26.2 FPS—a 48.0% reduction. This accelerated decline at 4K is a hallmark of VRAM exhaustion. The 4 GB frame buffer cannot hold the necessary textures and buffers at 4K, forcing the GPU to constantly swap data, which craters performance. The fact that the drop is consistent across settings—not just at Ultra—suggests that resolution alone is the trigger, not just texture quality.

The frame rate at 1080p Low (155.5 FPS) versus 1080p Ultra (75.9 FPS) shows a 51.2% reduction, which is purely GPU compute scaling. However, at 4K Low (54.3 FPS) versus 4K Ultra (26.4 FPS), the reduction is 51.4%, nearly identical. This indicates that the GPU is equally stressed by both resolution and settings, but the absolute FPS numbers at 4K are so low that neither setting matters much for playability. The CPU is not a factor here; the i5-12400F can easily feed the GPU at 4K, as evidenced by the consistent scaling percentages that match GPU workload expectations.

FAQ

Q: Can this combo run Pc Building Simulator at 1080p with High settings?

A: Yes. The measured data shows 81.6 FPS at 1920x1080 with High settings, which is well above the 60 FPS threshold for smooth gameplay. At Medium settings, it reaches 110.1 FPS, and at Ultra, it drops to 75.9 FPS, still playable.

Q: Is 4 GB of VRAM enough for 1440p gaming in this title?

A: It depends on settings. At 1440p Low, the combo hits 97.8 FPS, and at Medium, it hits 69.6 FPS. However, at High, it drops to 50.4 FPS, and at Ultra, it falls to 48.1 FPS. The 4 GB VRAM is sufficient for Low and Medium, but High and Ultra may cause stutter due to memory pressure.

Q: What is the biggest performance bottleneck at 4K resolution?

A: The GPU is the clear bottleneck. At 4K Medium, the combo only reaches 36.5 FPS, and at High, it drops to 26.2 FPS. The 4 GB VRAM and 192.0 GB/s bandwidth are insufficient for 4K workloads, as the frame rate drops by nearly 50% from 1440p.

Q: How does the i5-12400F compare to its nearest rival, the Intel Core i7-8700K?

A: The i5-12400F scores 19221 on average, while the i7-8700K scores 19210, a negligible 0.1% difference. This means the i5-12400F is effectively a match for the older i7 in synthetic benchmarks, so CPU performance should not be a deciding factor.

Q: At which settings does the combo exceed 100 FPS at 1080p?

A: At 1080p Low, the combo reaches 155.5 FPS, and at Medium, it reaches 110.1 FPS. These are the only two settings that break the 100 FPS barrier. High settings yield 81.6 FPS, and Ultra yields 75.9 FPS.

Q: What is the best resolution for this combo to maintain a playable frame rate?

A: 1920x1080 is the only resolution where all settings remain above 75 FPS. At 1440p, only Low (97.8 FPS) and Medium (69.6 FPS) are playable, while High and Ultra fall below 55 FPS. 4K is not recommended, as even Low settings only reach 54.3 FPS.

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

The measured FPS data is presented below, with average frame rates for each resolution and settings combination. No minimum or maximum FPS values were recorded, so only averages are listed.

1920x1080 (1080p):

• Low: 155.5 FPS
• Medium: 110.1 FPS
• High: 81.6 FPS
• Ultra: 75.9 FPS

2560x1440 (1440p):

• Low: 97.8 FPS
• Medium: 69.6 FPS
• High: 50.4 FPS
• Ultra: 48.1 FPS

3840x2160 (4K):

• Low: 54.3 FPS
• Medium: 36.5 FPS
• High: 26.2 FPS
• Ultra: 26.4 FPS

The pattern is consistent: each step up in settings reduces FPS, and each step up in resolution reduces FPS further. At 1080p, the spread from Low to Ultra is 79.6 FPS (155.5 to 75.9), indicating that the GPU has enough headroom to handle quality increases. At 1440p, the spread narrows to 49.7 FPS (97.8 to 48.1), showing that the GPU is starting to saturate. At 4K, the spread collapses to 28.1 FPS (54.3 to 26.4), meaning the GPU is fully maxed out regardless of settings. The 4K Ultra result (26.4 FPS) is slightly higher than 4K High (26.2 FPS), which is a minor anomaly likely due to measurement variance, but it does not change the overall conclusion.

Settings Recommendations — which preset gives the best experience per the measured rows

For a smooth experience at 60 FPS or higher, the data points to 1080p as the only viable resolution, with Medium settings being the sweet spot. At 1080p Medium, the combo achieves 110.1 FPS, which provides a comfortable margin above 60 FPS and leaves room for background tasks or streaming. Pushing to High at 1080p yields 81.6 FPS, which is still playable, but the extra visual fidelity may not be worth the 26% performance hit. Ultra at 1080p drops to 75.9 FPS, which is borderline but acceptable for a simulation game where precise timing is not critical.

At 1440p, the best experience is at Low settings, which delivers 97.8 FPS—the only 1440p setting that clears 60 FPS comfortably. Medium at 1440p hits 69.6 FPS, which is playable but close to the edge; if the game has complex scenes, it could dip below 60 FPS. High and Ultra at 1440p are not recommended, as they fall to 50.4 FPS and 48.1 FPS, respectively, which will feel sluggish. At 4K, no setting is recommended for serious play, as even Low only reaches 54.3 FPS, and the frame rate drops below 40 FPS for all other presets. The data suggests that users with a 4K monitor should either lower the resolution to 1440p or accept the visual compromise of Low settings.

The practical recommendation is to run the game at 1080p with Medium settings for the best balance of performance and visual quality. If the user prefers higher fidelity, High at 1080p is acceptable, but the frame rate drops below 100 FPS, which may be noticeable on high-refresh-rate displays. For 1440p users, Low settings are the only way to maintain a high refresh rate, while Medium is acceptable for 60 FPS gaming. The CPU is never the limiting factor, so users can focus on GPU settings without worrying about CPU bottlenecks.
