Pc Building Simulator

Pc Building Simulator is a simulation title where the workload is split between CPU-driven logic and GPU-accelerated rendering, and the benchmark data for the Intel Core Ultra 5 125H paired with the NVIDIA GeForce RTX 4080 shows a configuration that scales predictably with settings and resolution. The measured frames per second (FPS) range from a low of 53 at 4K Ultra to a high of 337 at 1080p Low, indicating that the game is highly sensitive to both components, with the CPU providing a strong baseline for high refresh rates at lower resolutions and the GPU becoming the primary constraint as pixel count rises.

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

The Intel Core Ultra 5 125H is a mobile processor from the Core Ultra Series 1, featuring 14 cores and 18 threads. Its base clock is 3.60 GHz with a boost clock of 4.50 GHz, and it is built on Intel's 7 nm process with the Meteor Lake architecture. The chip has a 28 W TDP, which classifies it as a power-efficient part, but the benchmark scores indicate it is far from a lightweight performer. In Cinebench R23, the CPU scores 12804.5 in multi-core and 1647.5 in single-core tests. The PassMark multithread score is 21100, and the single-thread score is 3399. These numbers place the CPU in the 79th percentile against all CPUs, with an average benchmark score of 27507.

When compared to its nearest rivals, the Core Ultra 5 125H is essentially a dead heat with the AMD Ryzen 7 5800, which has an average score of 27535 and a delta of -0.1%. The Intel Core i5-12600K and AMD Ryzen 7 5700X both score 27578, showing a delta of -0.3%, meaning the 125H is only marginally behind. The AMD Ryzen 3 PRO 5355G is the only rival that the 125H beats, with a delta of 0.5% against a score of 27382. For a simulation game, this level of CPU performance is more than adequate, as the game's logic, part compatibility checks, and system building calculations benefit from the 18 threads and the 18 MB of shared L3 cache.

The clock speeds matter in Pc Building Simulator because the game's menus and 3D rendering of components are not heavily parallelized. The single-core Cinebench R23 score of 1647.5, coupled with a 4.50 GHz boost clock, ensures that the game's user interface remains responsive even when the GPU is rendering at high settings. The data shows that at 1080p Low, the CPU can push the FPS to 337, which suggests that the processor is not a bottleneck at lower resolutions. However, it is the combination of the CPU's 14 cores and the GPU's capability that defines the overall experience, as the simulation aspects of the game can still create CPU overhead during complex builds.

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

The measured FPS data provides clear guidance on which settings preset delivers the optimal experience. At 1920x1080, the High preset yields an average of 169 FPS, while the Ultra preset drops to 161 FPS. The Medium preset sits at 239 FPS, and the Low preset reaches 337 FPS. The difference between High and Ultra is only 8 FPS, which is negligible for most users, but the Ultra preset at 4K drops to 53 FPS, which is below the 60 FPS threshold. For a simulation game, the recommendation is to prioritize stability over maximum visual fidelity, and the data shows that the High preset at 1440p offers 106 FPS, which is a smooth experience.

Looking at the 2560x1440 resolution, the High preset provides 106 FPS, and the Medium preset provides 151 FPS with a minimum FPS of 128 and a maximum of 173. The Ultra preset at this resolution still manages 101 FPS, which is playable, but the jump from Ultra to High is only 5 FPS, making High the more sensible choice if there are any concerns about frame time spikes. At 1080p, the Medium preset is the standout, offering 239 FPS with a minimum of 203 and a maximum of 275. This is nearly 70 FPS more than High and 100 FPS more than Ultra, suggesting that Medium is the sweet spot for high refresh rate monitors.

At 4K, the Medium preset delivers 79 FPS with a minimum of 67 and a maximum of 91. This is the only preset at 4K that crosses the 60 FPS threshold comfortably, as High sits at 56 FPS and Ultra at 53 FPS. The Low preset at 4K achieves 111 FPS, which is remarkable for a mobile CPU and high-end GPU combination, but the visual quality of Low is often undesirable in a game that revolves around inspecting components. The best experience per the measured rows is the Medium preset at 1440p, which balances the 151 FPS average with a minimum of 128 FPS, ensuring no noticeable stutter during gameplay.

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

The FPS scaling from 1080p to 4K reveals the expected shift in bottleneck from the CPU to the GPU. At 1080p High, the average FPS is 169, and at 1440p High, it is 106, which is a 37% reduction. Moving to 4K High, the FPS drops to 56, which is a 67% reduction from 1080p. This pattern is consistent with the GPU becoming the limiting factor as the pixel count increases. The RTX 4080, with its 16 GB of GDDR6X memory and 716.8 GB/s bandwidth, is a strong performer, but it still encounters a significant workload at 4K.

The Low preset shows a different scaling curve. At 1080p Low, the FPS is 337, which drops to 213 at 1440p Low (a 37% reduction) and then to 111 at 4K Low (a 48% reduction from 1440p). This suggests that at Low settings, the CPU is still contributing to the frame rate, as the reduction from 1080p to 1440p is not as steep as the reduction from 1440p to 4K. The data indicates that at 1080p Low, the CPU is the primary driver, allowing the GPU to render frames quickly, but as resolution increases, the GPU's fill rate and memory bandwidth become the deciding factors.

The Medium preset shows a similar trend, with 239 FPS at 1080p, 151 FPS at 1440p, and 79 FPS at 4K. The drop from 1080p to 1440p is 37%, and from 1440p to 4K is 48%. This consistent scaling suggests that the game engine is well-optimized for resolution changes, but the limiting component is clearly the GPU at higher resolutions. For a simulation game, this is expected, as the CPU handles the game logic while the GPU renders the 3D components. The RTX 4080's 48.74 TFLOPS of FP32 performance is sufficient for 4K Medium, but the 53 FPS at 4K Ultra indicates that the game's ultra settings are too demanding for a smooth experience.
