Pc Building Simulator

Pc Building Simulator, a simulation title focused on the assembly and maintenance of virtual PCs, presents a unique workload that stresses both CPU and GPU capabilities. The Intel Core Ultra 7 155H paired with the NVIDIA GeForce RTX 5090 Mobile delivers a performance profile that scales predictably with resolution and settings. The measured data reveals a combination that is exceptionally strong at 1080p and 1440p, with 4K performance remaining playable but demanding careful settings selection.

Settings Recommendations

The measured frame rates across all three resolutions and four quality presets indicate that this hardware combination has substantial headroom. For users prioritizing the smoothest experience at high refresh rates, the Low preset delivers exceptional performance, with the combo achieving 345 FPS at 1080p, 244 FPS at 1440p, and 127 FPS at 4K. These figures are far beyond the refresh rate of typical displays, making the Low preset more of a benchmark tool than a practical gaming choice.

The Medium preset offers a significantly better balance between visual fidelity and frame rate. At 1080p, the average of 274 FPS remains incredibly high, while the 1440p average of 173 FPS is still well above 144Hz displays. The 4K Medium setting produces an average of 90 FPS with a minimum of 77 FPS and a maximum of 104 FPS, which is a solidly playable range for a simulation game that doesn't demand twitch-reflex reactions. The measured minimum of 77 FPS at 4K Medium confirms that frame pacing remains stable even under load.

The High preset is the recommended sweet spot for visual quality without sacrificing playability. At 1080p, the combo still delivers a staggering 193 FPS, and at 1440p it maintains a strong 122 FPS. The 4K High setting drops to 64 FPS, which is playable but approaches the threshold where some users might prefer lower settings for a higher refresh rate. The Ultra preset, while providing the maximum visual detail, shows a noticeable performance hit: 184 FPS at 1080p, 116 FPS at 1440p, and 61 FPS at 4K.

Benchmark results indicate that the Ultra preset at 4K is the only configuration that dips below the 60 FPS target, which is a critical consideration for users with high-refresh-rate 4K displays. For the best overall experience, the data suggests using the High preset at 1440p, as it provides a 122 FPS average that balances the visual improvements over Medium with a substantial performance margin over Ultra. At 4K, the Medium preset is the most sensible choice, as its 90 FPS average is significantly smoother than the 64 FPS of High while still offering a considerable visual upgrade over Low.

GPU Role

The NVIDIA GeForce RTX 5090 Mobile is the dominant component in this pairing for Pc Building Simulator. The GPU's architecture, Blackwell 2.0, is built on a 5 nm process at TSMC, and its specifications are substantial: 24 GB of GDDR7 memory on a 256-bit bus, providing 896.0 GB/s of bandwidth. The GPU features 10496 shading units, 328 texture mapping units, and 112 raster output pipelines. Its clock speeds are listed with a base of 990 MHz and a boost of 1515 MHz, with memory running at 1750 MHz (28 Gbps effective).

The GPU's memory capacity and bandwidth are more than sufficient for a simulation game that involves managing inventory, building systems, and running virtual benchmarks. The data shows that the RTX 5090 Mobile's raw compute power is the primary driver of frame rates, as the performance deltas between settings presets are significant. For instance, at 1440p, the difference between Low (244 FPS) and Ultra (116 FPS) is a 128 FPS drop, which correlates with the increasing load on the GPU's shading units and texture units due to higher quality effects and geometry.

The RTX 5090 Mobile's percentile ranking of 84 against all GPUs, combined with its average benchmark score, indicates it is a top-tier mobile part. Its nearest rival in the benchmark database is the AMD Radeon Pro 5500 XT, which has a deltaPct of -0.5, meaning the RTX 5090 Mobile performs slightly below that rival in synthetic tests. However, this is a synthetic score comparison, and the measured FPS in Pc Building Simulator shows the GPU's real-world strength. The GPU's 3DMark Steel Nomad DX12 score of 5871 and Passmark G3D score of 30034 further confirm its high-end positioning.

The GPU's role becomes more critical as resolution increases. At 1080p, the CPU has enough power to feed the GPU in most scenarios, but the data suggests the GPU is still the bottleneck at higher settings. The jump from High to Ultra at 1080p results in a 9 FPS drop (from 193 to 184), which is relatively small. However, at 4K, the same settings change results in a 3 FPS drop (from 64 to 61), indicating that the GPU is reaching its limits in terms of pixel throughput. The RTX 5090 Mobile's 31.80 TFLOPS of FP32 performance is the key metric here, as it dictates how quickly the GPU can process the complex shaders required for high-resolution rendering.

Resolution Scaling

The measured FPS data shows a clear and expected scaling pattern as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average frame rate drops from 193 FPS at 1080p to 122 FPS at 1440p, a reduction of 71 FPS. Moving to 4K, the average drops further to 64 FPS, which is a 58 FPS reduction from the 1440p figure. This represents a total drop of 129 FPS from 1080p to 4K, which is a 66.8% decrease in performance.

This scaling pattern indicates that the GPU is the primary limiting component at higher resolutions. The number of pixels rendered at 4K is four times that of 1080p, and the RTX 5090 Mobile's performance does not scale linearly with pixel count due to other bottlenecks like memory bandwidth and fill rate. The 896.0 GB/s of memory bandwidth is substantial, but it is still a finite resource that gets taxed more heavily as the resolution increases.

For the Low preset, the scaling is even more dramatic. The combo achieves 345 FPS at 1080p, which drops to 244 FPS at 1440p and then to 127 FPS at 4K. The relative drop from 1080p to 4K is 218 FPS, or 63.2%. The fact that the Low preset at 4K (127 FPS) is still higher than the Ultra preset at 1080p (184 FPS) highlights how much of the GPU's power is consumed by higher quality settings rather than just resolution.

The Medium preset shows the most stable minimum frame rates, with the data providing min/max figures for each resolution. At 1080p, the average is 274 FPS with a minimum of 233 FPS and a maximum of 315 FPS. At 1440p, the average is 173 FPS with a minimum of 147 FPS and a maximum of 199 FPS. At 4K, the average is 90 FPS with a minimum of 77 FPS and a maximum of 104 FPS. The relatively narrow gap between average and minimum FPS suggests that the rendering workload is consistent, which is typical for a simulation game that doesn't have sudden spikes in complexity.

The data suggests that the Intel Core Ultra 7 155H is not a bottleneck at 1080p, as the GPU is still able to push out very high frame rates. However, as resolution increases, the load shifts almost entirely to the GPU. The CPU's 22 threads and 24 MB of L3 cache are likely sufficient to handle the simulation logic and game state updates, while the GPU's 10496 shading units are responsible for the pixel throughput. This is a classic example of a balanced gaming laptop configuration where the GPU becomes the limiting factor at higher resolutions.
