CPU Role

The Intel Core Ultra 5 125H is a mobile processor with 14 cores and 18 threads, built on Intel’s Meteor Lake architecture using a 7 nm process. Its base clock is 3.60 GHz with a boost clock of 4.50 GHz, and it features 18 MB of shared L3 cache alongside per-core L1 and L2 allocations of 112 KB and 2 MB, respectively. In Pc Building Simulator, the CPU handles the logic of component compatibility, power draw calculations, and system boot sequences, which are computationally lighter than physics or AI in action games.

Benchmark results show the processor’s strengths in multi-threaded workloads. Its Cinebench R23 multi-core score is 12804.5, while the single-core score is 1647.5. The PassMark multithread score reaches 21100, and the single-thread score is 3399. These figures position the chip near the 79th percentile of all CPUs, with an average benchmark score of 27507. The nearest rival, the AMD Ryzen 7 5800, scores 27535, a delta of -0.1%, meaning the Intel part is effectively equivalent in raw compute.

The CPU’s role becomes more apparent at lower resolutions. At 1080p Low, the combo produces 338 FPS, which is a massive frame rate that suggests the GPU is not the limiting factor. The CPU’s 18 threads and 4.50 GHz boost clock are sufficient to feed the RTX 5090 at these settings, as the simulation’s logic does not create a bottleneck. However, the data shows that the CPU’s influence wanes as resolution increases. At 4K Ultra, the average FPS drops to 61, indicating that the GPU’s rendering load dominates the frame time, while the CPU remains underutilized relative to its capabilities.

The processor’s 28 W TDP and mobile market segment suggest it is designed for efficiency, but in this desktop-like benchmark context, the power draw does not translate into a performance deficit. The memory bandwidth of 89.6 GB/s for the CPU is modest compared to the GPU’s 1.79 TB/s, but for a simulation game that primarily relies on single-threaded logic for menu interactions and build validation, the 1647.5 single-core score in Cinebench R23 is the more relevant metric. This score is competitive enough to avoid holding back the RTX 5090 in most scenarios, as evidenced by the high frame rates at 1080p and 1440p.

GPU Role

The NVIDIA GeForce RTX 5090 is the flagship of the Blackwell 2.0 architecture, built on a 5 nm process at TSMC with 92,200 million transistors on a 750 mm² die. It features 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. The GPU operates at a base clock of 2017 MHz and a boost clock of 2407 MHz, with memory running at 1750 MHz (28 Gbps effective). Its 21,760 shading units and 176 ROPs provide massive raw throughput, with a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s.

In Pc Building Simulator, the GPU’s primary role is rendering the 3D workspace, including the case, components, and lighting effects. The 32 GB VRAM is far more than the game requires, but it ensures that texture loading and scene complexity never cause stutter or asset swapping. The GPU’s benchmark scores reflect its dominance: a 3DMark Steel Nomad DX12 score of 18355, a Geekbench OpenCL score of 334370, and a PassMark G3D score of 39650. The GPU sits at the 92nd percentile of all GPUs, with an average benchmark score of 79842.

The nearest GPU rival is the NVIDIA Tesla P100 PCIe 16 GB, which scores 79605, a delta of 0.3% lower. This indicates that the RTX 5090 is marginally ahead of a professional compute card in synthetic tests, but the gaming-specific advantage comes from its 32 GB VRAM and 1.79 TB/s bandwidth. The data shows this advantage plays out in the measured FPS. At 4K Ultra, the combo achieves 61 FPS, which is a minimum threshold for smooth gameplay, and at 4K Medium, it reaches 90 FPS with a minimum of 77 FPS. These results suggest the GPU is the primary driver of performance at high resolutions and settings.

The GPU’s 575 W TDP and 950 W suggested PSU are indicative of its power appetite, but the performance scaling justifies the energy cost. At 1440p High, the average FPS is 122, and at 1080p High, it jumps to 193. The GPU’s ability to maintain high frame rates across all settings demonstrates that it is not the bottleneck until 4K Ultra, where the rendering workload overwhelms even this flagship part. The RTX 5090’s 104.8 TFLOPS of FP32 compute is more than sufficient for a simulation game, and the data confirms that the GPU delivers consistent performance without thermal or clock throttling in the measured scenarios.

How This Combo Ranks

The Intel Core Ultra 5 125H and NVIDIA GeForce RTX 5090 combination ranks 584th out of 3002 tested combos in Pc Building Simulator. This position places the pairing in the top 19.4% of all configurations, which is a solid result but not a top-tier performance for this specific game. The ranking reflects a mismatch between the CPU and GPU: the RTX 5090 is a flagship desktop GPU, while the Core Ultra 5 125H is a mobile processor with a 28 W TDP. This asymmetry means the CPU is likely the limiting factor in CPU-bound scenarios, such as at 1080p Low where the frame rate of 338 FPS is high but still below what a more powerful desktop CPU might achieve with the same GPU.

The combo’s rank is influenced by the game’s genre. Pc Building Simulator is not graphically intensive compared to AAA shooters, so the GPU’s 32 GB VRAM and 1.79 TB/s bandwidth are overkill for the majority of scenes. The CPU’s 14 cores and 18 threads are adequate for the simulation’s logic, but the 4.50 GHz boost clock is modest for a high-end pairing. The data shows that the combo performs best at 1440p and 1080p, where the frame rates exceed 100 FPS on High settings, but it struggles to maintain 60 FPS at 4K Ultra, which is a common target for flagship GPUs.

Compared to other combos in the database, this pairing’s rank suggests that while the RTX 5090 is a top-tier GPU, the CPU drags down the overall performance in this title. The CPU’s average benchmark score of 27507 is nearly identical to the AMD Ryzen 7 5800, which is a desktop part from a previous generation. This indicates that the Core Ultra 5 125H is not a performance leader, and its mobile design limits its ability to fully utilize the RTX 5090 in demanding scenarios. However, the rank of 584 out of 3002 is still above average, and the combo delivers playable frame rates at all tested settings except 4K Ultra, where it barely reaches 61 FPS.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance scaling as resolution increases from 1080p to 4K. At 1080p High, the combo achieves 193 FPS, which drops to 122 FPS at 1440p High, a 36.8% reduction. Continuing to 4K High, the frame rate falls to 64 FPS, which is a 47.5% reduction from 1440p and a 66.8% reduction from 1080p. This scaling indicates that the GPU is the primary bottleneck at higher resolutions, as the pixel count increases exponentially and the RTX 5090’s rendering workload grows.

The same pattern holds for Low settings. At 1080p Low, the combo produces 338 FPS, which drops to 244 FPS at 1440p Low and 127 FPS at 4K Low. The percentage drop from 1080p to 1440p is 27.8%, and from 1440p to 4K is 48.0%. This consistent scaling suggests that the CPU is not a limiting factor at low settings, as the frame rates remain high enough to keep the GPU busy. At Medium settings, the frame rates are 274 FPS at 1080p, 173 FPS at 1440p, and 90 FPS at 4K, with minimums of 233, 147, and 77 FPS, respectively.

The data also shows that the gap between settings widens at higher resolutions. At 1080p, the difference between Low and Ultra is 154 FPS (338 vs. 184). At 1440p, the difference is 128 FPS (244 vs. 116). At 4K, the difference narrows to 66 FPS (127 vs. 61). This narrowing indicates that at 4K, the GPU is so heavily loaded that even Low settings cannot produce the extreme frame rates seen at lower resolutions. The limiting component at 4K is clearly the GPU, as the CPU’s role diminishes with higher pixel counts. The RTX 5090’s 32 GB VRAM and 1.79 TB/s bandwidth are sufficient to handle the data, but the sheer compute required to render 4K scenes forces the average FPS below 100 at all settings except Low.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo’s performance across three resolutions and four settings presets. At 1920x1080, the average FPS ranges from 184 at Ultra to 338 at Low. The Medium preset delivers 274 FPS with a minimum of 233 and a maximum of 315, while High comes in at 193 FPS. These numbers indicate that at 1080p, the combo is massively overqualified for the game, and the frame rates are limited by the CPU’s ability to process the simulation logic rather than the GPU’s rendering power.

At 2560x1440, the average FPS drops to 116 at Ultra, 122 at High, 173 at Medium, and 244 at Low. The Medium preset shows a minimum of 147 and a maximum of 199 FPS. This resolution represents a balance point where the GPU begins to take on more work, but the frame rates remain high enough for smooth gameplay on any monitor. The 1440p results show a 36.8% drop from 1080p at High settings, confirming that the GPU is becoming a more significant factor.

At 3840x2160, the average FPS falls to 61 at Ultra, 64 at High, 90 at Medium, and 127 at Low. The Medium preset is the only one with a recorded minimum, at 77 FPS, and a maximum of 104 FPS. The 4K results show that Ultra settings barely maintain 60 FPS, which is a common target for console-like experiences, while High settings are only marginally better at 64 FPS. The 4K Low setting at 127 FPS is still playable, but the 66 FPS gap between Low and Ultra demonstrates the GPU’s limitations at this resolution. The data suggests that for 4K gaming, the combo is best used with Medium or High settings to maintain frame rates above 90 FPS, while Low settings are unnecessary given the GPU’s capabilities.
