Pc Building Simulator

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

The Intel Core i7-12700KF is a 12-core, 20-thread Alder Lake-S desktop processor with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its 25 MB of shared L3 cache and 1.25 MB per-core L2 cache provide ample bandwidth for simulation workloads. The chip scores 89th percentile against all CPUs, with an average benchmark score of 35,355. Its nearest rival, the Intel Core i7-13800H, scores 35,416 — a delta of -0.2%, meaning the i7-12700KF essentially trades blows with that mobile flagship.

In Pc Building Simulator, the CPU's role is central because the game simulates component interactions, thermal behavior, and system boot sequences — all of which are heavily threaded. The data shows the 3dmark_max_threads score of 9,983 and cinebench_r23_multicore score of 28,979 demonstrate strong parallel throughput. Meanwhile, the 3dmark_single_thread score of 1,043 and cinebench_r23_singlecore score of 4,091 show this processor still handles single-threaded bottlenecks effectively.

The benchmark results indicate that at 1080p Low settings — where the GPU is least burdened — the combo reaches 400.7 FPS. This extreme frame rate suggests the CPU is capable of feeding the RTX 5080 even at low resolutions where the graphics card would normally be the limiting factor. At 4K Ultra, the frame rate drops to 78 FPS, which indicates the GPU becomes the dominant constraint at higher resolutions. The i7-12700KF's 89th percentile ranking and its proximity to the Intel Core i5-14400 (delta 0.1%, score 35,336) confirm it is a balanced companion for this simulation title.

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

The NVIDIA GeForce RTX 5080 is a Blackwell 2.0 architecture GPU with 16 GB of GDDR7 memory on a 256-bit bus, delivering 960.0 GB/s of bandwidth. Its base clock runs at 2295 MHz with a boost clock of 2617 MHz, and the memory operates at 1875 MHz (30 Gbps effective). The GPU scores 89th percentile against all GPUs with an average benchmark score of 59,188. Its nearest rival, the Intel Arc Pro A60, scores 60,326 — a delta of -1.9%, meaning the RTX 5080 slightly trails that workstation card in aggregate benchmarks, though the PassMark G3D score of 36,565 shows raw rasterization strength.

In Pc Building Simulator, the GPU's contribution scales directly with settings and resolution. At 1080p Low, the RTX 5080 achieves 400.7 FPS, but this is not a GPU-bound scenario — the frame rate ceiling is likely imposed by the CPU or engine limits. At 4K Ultra, the GPU is fully engaged, producing 78 FPS. The 16 GB VRAM is ample for this simulation, as the game does not appear to exceed memory capacity even at 4K Ultra, given the consistent performance scaling.

The 3dmark_steel_nomad_dx12 score of 8,637 indicates the GPU handles modern DirectX 12 workloads, which aligns with the game's simulation rendering. The PassMark DirectX 12 score of 151, while low in absolute terms, reflects the synthetic benchmark's methodology rather than real-world gaming performance. The RTX 5080's 45,600 million transistors and 10752 shading units provide substantial compute headroom, though Pc Building Simulator's frame rates at Ultra settings suggest the GPU is the primary bottleneck at 4K.

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

The measured data shows diminishing returns when moving from High to Ultra settings. At 4K, High produces 79.8 FPS while Ultra drops to 78 FPS — a negligible 1.8 FPS difference. At 1440p, High yields 156.9 FPS versus Ultra's 149.6 FPS, a 7.3 FPS gap. At 1080p, High delivers 246.9 FPS and Ultra 239.3 FPS, a 7.6 FPS difference. The High preset provides nearly all the visual fidelity of Ultra with measurably better frame rates across all resolutions.

Medium settings offer significantly higher frame rates: 117 FPS at 4K, 223.4 FPS at 1440p, and 351.4 FPS at 1080p. However, the jump from Medium to High at 1440p costs 66.5 FPS (from 223.4 to 156.9), which is a substantial performance hit for what is likely a modest visual improvement in a simulation game. Low settings provide the highest frame rates — 163.5 FPS at 4K, 314.2 FPS at 1440p, and 400.7 FPS at 1080p — but these come with reduced visual quality that may compromise the simulation experience.

The benchmark results indicate that High is the optimal preset for this combo. It delivers 79.8 FPS at 4K, which is above the 60 FPS threshold for smooth gameplay. At 1440p, High's 156.9 FPS leaves ample headroom for refresh rates up to 144 Hz. At 1080p, the 246.9 FPS exceeds all but the most extreme high-refresh displays. Ultra offers no meaningful advantage over High in this game, making it an unnecessary performance sacrifice.

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

The performance scaling from 1080p to 4K reveals the balance between CPU and GPU limitations. At High settings, the combo delivers 246.9 FPS at 1080p, 156.9 FPS at 1440p, and 79.8 FPS at 4K. The drop from 1080p to 1440p is 90 FPS (36.5% reduction), while the drop from 1440p to 4K is 77.1 FPS (49.1% reduction). This accelerating decline as resolution increases confirms the GPU becomes progressively more dominant as the limiting factor.

At Low settings, the frame rates are 400.7 FPS at 1080p, 314.2 FPS at 1440p, and 163.5 FPS at 4K. The 1080p-to-1440p drop is 86.5 FPS (21.6% reduction), but the 1440p-to-4K drop is 150.7 FPS (48.0% reduction). The relatively smaller percentage drop at lower resolutions suggests the CPU is more involved in capping performance at 1080p Low, where the GPU has less work to do.

Ultra settings show a similar pattern: 239.3 FPS at 1080p, 149.6 FPS at 1440p, and 78 FPS at 4K. The 1080p-to-1440p reduction is 89.7 FPS (37.5%), while 1440p-to-4K is 71.6 FPS (47.9%). These consistent trends across all settings indicate that at 1080p, the i7-12700KF is still a meaningful contributor to overall frame rates, but at 4K, the RTX 5080's rendering workload dominates.

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

At 1920x1080, the combo achieves 400.7 FPS on Low, 351.4 FPS on Medium, 246.9 FPS on High, and 239.3 FPS on Ultra. The gap between Low and Medium is 49.3 FPS, while Medium to High costs 104.5 FPS. The High-to-Ultra difference is only 7.6 FPS, showing diminishing returns.

At 2560x1440, the results are 314.2 FPS on Low, 223.4 FPS on Medium, 156.9 FPS on High, and 149.6 FPS on Ultra. The Low-to-Medium drop is 90.8 FPS, Medium-to-High costs 66.5 FPS, and High-to-Ultra costs 7.3 FPS.

At 3840x2160, the measured numbers are 163.5 FPS on Low, 117 FPS on Medium, 79.8 FPS on High, and 78 FPS on Ultra. The Low-to-Medium reduction is 46.5 FPS, Medium-to-High costs 37.2 FPS, and High-to-Ultra only costs 1.8 FPS.

Across all resolutions, the Ultra preset provides virtually no benefit over High, with differences ranging from 1.8 FPS at 4K to 7.6 FPS at 1080p. The Medium preset offers a meaningful performance boost over High, but at 4K it still falls below 120 FPS. Low settings provide the highest frame rates but at the cost of visual fidelity.
