Pc Building Simulator

# Pc Building Simulator — Intel Core Ultra 5 125H + NVIDIA GeForce RTX 4090

The pairing of Intel's Core Ultra 5 125H mobile processor with NVIDIA's flagship RTX 4090 desktop GPU produces benchmark results that are heavily skewed toward the graphics card in Pc Building Simulator. The measured data shows a system capable of very high frame rates across all tested resolutions and settings, with the CPU rarely acting as a limiting factor at lower settings. This analysis breaks down the exact FPS measurements, scaling behavior, and the respective roles of each component in this specific title.

Settings Recommendations

The measured FPS rows across three resolutions and four quality presets reveal a clear pattern: this combo delivers playable frame rates even at the most demanding settings, but the optimal experience depends on the display's native resolution.

At 1920x1080, the Ultra preset averages 176 FPS, while High averages 185 FPS. The delta between High and Ultra is only 9 FPS, making Ultra the recommended choice for 1080p users who want maximum visual fidelity without sacrificing smoothness. The Medium preset at 262 FPS and Low at 338 FPS are excessive for standard 60Hz or 144Hz displays, offering no practical benefit over Ultra. The data suggests that at 1080p, the GPU has so much headroom that the visual quality gains from Ultra outweigh the minor FPS cost.

Moving to 2560x1440, the Ultra preset averages 111 FPS, which is still comfortably above the 60 FPS threshold for smooth gameplay. High averages 117 FPS, only 6 FPS higher than Ultra. Given that Pc Building Simulator is a simulation title where visual detail contributes to the experience, Ultra at 1440p is the recommended preset—the 111 FPS average remains high enough for responsive interaction, and the increased shadow quality, texture filtering, and post-processing effects are worthwhile. The Medium preset at 165 FPS and Low at 233 FPS are available for users with high-refresh-rate 1440p displays, but they sacrifice visual fidelity for frame rates that exceed what most monitors can display.

At 3840x2160, the picture changes significantly. Ultra averages 58 FPS, which dips below the 60 FPS threshold and may introduce perceptible stutter. High averages 61 FPS, essentially the same performance envelope. Medium averages 86 FPS with a minimum of 73 FPS and a maximum of 99 FPS, providing a much safer margin above 60 FPS. For 4K users, the Medium preset is the recommended choice—it delivers 86 FPS average with a minimum of 73 FPS, ensuring consistent smoothness, while still offering respectable visual quality. The Low preset at 122 FPS is overly conservative for 4K, as the visual degradation is noticeable without a proportional performance need.

The overall recommendation across all resolutions is to use Ultra at 1080p and 1440p, and Medium at 4K. This balances visual quality against the measured FPS data, ensuring that the average frame rate never falls below 86 FPS while maintaining the highest settings that the hardware can sustain.

How This Combo Ranks

The combination of the Core Ultra 5 125H and RTX 4090 ranks 714th out of 3002 tested combos in Pc Building Simulator. This places it in the top 23.8% of all configurations tested, which is notable given that the CPU is a mobile part with modest specifications compared to desktop alternatives.

The rank reflects the unusual pairing of a mobile processor with a flagship desktop GPU. While the RTX 4090 is among the most powerful graphics cards available, the Core Ultra 5 125H's mobile design—with its 28W TDP and 14 cores—limits the overall system's potential in this game. The ranking of 714 suggests that many desktop CPU + GPU combinations outperform this pairing, likely because desktop CPUs offer higher sustained clocks and better memory bandwidth for simulation workloads.

However, the rank should not be interpreted as poor performance. The measured FPS data shows that this combo delivers at least 58 FPS at 4K Ultra and above 176 FPS at 1080p Ultra, which is far above what most systems achieve. The ranking is relative to other tested combos, and the fact that 714th place still yields these frame rates indicates that Pc Building Simulator is not an exceptionally demanding title for high-end hardware.

The GPU's percentile ranking of 88th versus all GPUs and the CPU's percentile of 79th versus all CPUs suggest both components are above average, but the gap between them—with the GPU performing relatively better—explains why the combo rank (714 out of 3002) is not higher. The CPU is the weaker link in this pairing, and its mobile nature likely prevents the system from achieving the top-tier rankings that a desktop counterpart might reach.

Measured FPS Breakdown

At 1920x1080, the measured FPS data shows a wide range across settings. Low settings produce an average of 338 FPS, which is the highest of any configuration tested. Medium settings average 262 FPS, with a minimum of 222 FPS and a maximum of 301 FPS. High settings average 185 FPS, and Ultra settings average 176 FPS. The delta between High and Ultra is only 9 FPS, while the delta between Low and Medium is 76 FPS, indicating diminishing returns as settings increase.

At 2560x1440, the FPS values scale down proportionally. Low settings average 233 FPS, which is still exceptionally high. Medium settings average 165 FPS, with a minimum of 140 FPS and a maximum of 190 FPS. High settings average 117 FPS, and Ultra settings average 111 FPS. The delta between High and Ultra narrows to 6 FPS, while the delta between Low and Medium is 68 FPS. The minimum FPS at Medium settings (140) remains above the 60 FPS threshold by a substantial margin.

At 3840x2160, the FPS values drop significantly. Low settings average 122 FPS, which is still highly playable. Medium settings average 86 FPS, with a minimum of 73 FPS and a maximum of 99 FPS. High settings average 61 FPS, and Ultra settings average 58 FPS. The delta between High and Ultra is only 3 FPS, while the delta between Low and Medium is 36 FPS. The minimum FPS at Medium settings (73) is above 60 FPS, but the Ultra average of 58 FPS falls below the threshold.

The data reveals a consistent pattern: the gap between Low and Medium settings is always larger than the gap between High and Ultra settings, across all three resolutions. This suggests that the Low preset removes many rendering features that significantly impact performance, while the High-to-Ultra transition adds relatively minor effects.

Resolution Scaling

The FPS scaling from 1080p to 4K is not linear and reveals important information about the system's bottleneck. At High settings, the FPS drops from 185 at 1080p to 117 at 1440p to 61 at 4K. This represents a 36.8% decrease from 1080p to 1440p, and a 47.9% decrease from 1440p to 4K. The drop from 1080p to 4K is 67.0%, which is less than the 75% reduction in pixel count (from 2.07 million pixels to 8.29 million pixels), indicating that the system is not purely pixel-bound.

At Medium settings, the FPS drops from 262 at 1080p to 165 at 1440p to 86 at 4K. This represents a 37.0% decrease from 1080p to 1440p, and a 47.9% decrease from 1440p to 4K. The total drop from 1080p to 4K is 67.2%, nearly identical to the High settings scaling. At Low settings, the FPS drops from 338 at 1080p to 233 at 1440p to 122 at 4K, representing a 31.1% decrease from 1080p to 1440p and a 47.6% decrease from 1440p to 4K.

The consistent scaling pattern across all settings suggests that the limiting component is the GPU, not the CPU. If the CPU were the bottleneck, we would expect to see smaller FPS drops at lower resolutions where the CPU is under more relative load. Instead, the FPS scales almost exactly with the pixel count, indicating that the RTX 4090 is the primary determinant of performance.

However, the fact that the FPS drop from 1080p to 4K (approximately 67%) is less than the pixel count increase (75%) suggests that the CPU does exert some influence at 1080p. At 1080p Low, the 338 FPS average may be limited by the Core Ultra 5 125H's single-thread performance, preventing the GPU from reaching its full potential. The smaller relative drops at 1440p and 4K indicate that the GPU becomes fully utilized at these higher resolutions.

CPU Role

The Intel Core Ultra 5 125H is a mobile processor with 14 cores and 18 threads, based on the Meteor Lake architecture manufactured on Intel's 7 nm process. Its base clock is 3.60 GHz with a boost clock of 4.50 GHz, and it has a 28W TDP. The processor features 18 MB of shared L3 cache, 2 MB of L2 cache per core, and 112 KB of L1 cache per core.

In Pc Building Simulator, the CPU's role is primarily to handle game logic, simulation calculations, and the UI elements that track PC component specifications. The game's simulation nature means that CPU performance can affect the speed at which the game processes building and testing actions. The measured FPS data shows that the CPU is not the primary bottleneck at higher resolutions, but it may limit performance at 1080p.

The CPU's synthetic benchmarks show a Cinebench R23 multi-core score of 12804.5 and a single-core score of 1647.5. Its PassMark single-thread score is 3399, and its multi-thread score is 21100. These scores place the CPU in the 79th percentile versus all CPUs, with an average benchmark score of 27507. The nearest rival, the AMD Ryzen 7 5800, scores 27535, which is only 0.1% higher, indicating that the Core Ultra 5 125H performs essentially identically to that desktop CPU in synthetic workloads.

The 14-core/18-thread configuration provides ample multi-threading for simulation games, and the boost clock of 4.50 GHz is high enough for single-threaded tasks. However, the mobile form factor and 28W TDP mean that sustained clocks may be lower than a desktop processor during extended gaming sessions. The data does not include sustained clock measurements, but the FPS results suggest that the CPU maintains sufficient performance to keep the RTX 4090 fed at 1440p and 4K.

GPU Role

The NVIDIA GeForce RTX 4090 is the flagship of the GeForce 40-series, based on the AD102 chip on TSMC's 5 nm process. It features 16,384 shading units, 512 TMUs, and 176 ROPs, with 128 RT cores and 512 tensor cores. The GPU has 24 GB of GDDR6X memory on a 384-bit bus, providing 1.01 TB/s of memory bandwidth. Its base clock is 2235 MHz with a boost clock of 2520 MHz, and it has a TDP of 450W.

In Pc Building Simulator, the GPU handles all rendering tasks, including the 3D views of PC components, case lighting, and visual effects. The game's simulation nature means that the GPU workload is primarily visual, with less reliance on complex physics or particle effects than action games. The measured FPS data shows that the RTX 4090 is the dominant performance factor, with FPS scaling almost linearly with pixel count.

The GPU's synthetic benchmarks show a PassMark G3D score of 38194 and a PassMark G2D score of 1299. Its 3DMark Steel Nomad DX12 score is 9223, and its Geekbench OpenCL score is 255416 with a Vulkan score of 271631. These scores place the GPU in the 88th percentile versus all GPUs, with an average benchmark score of 60347. The nearest rival, the Intel Arc Pro A60, scores 60326, which is 0% different, while the AMD Radeon Pro W6600M scores 61896, which is 2.5% higher.

The 24 GB of VRAM is far more than Pc Building Simulator requires, even at 4K Ultra settings. The GPU's memory bandwidth of 1.01 TB/s ensures that texture streaming and high-resolution assets are handled without stutter. The boost clock of 2520 MHz provides substantial compute throughput, and the FP32 performance of 82.58 TFLOPS is more than sufficient for the game's rendering demands.

The GPU's role is clear: it is the primary determinant of FPS across all resolutions and settings. At 1080p, the GPU is underutilized, as evidenced by the 338 FPS average at Low settings, but it still delivers excellent performance. At 4K, the GPU is fully utilized, with the 58-122 FPS range across settings reflecting its raw rendering power. The RTX 4090's end-of-life production status and 1,599 USD launch MSRP position it as a high-end component, and the measured FPS data confirms that it delivers flagship-level performance in this simulation title.
