Pc Building Simulator

Pc Building Simulator is a simulation title that tasks players with assembling and troubleshooting virtual hardware, and its performance profile reveals a system that is heavily CPU-bound at lower resolutions before shifting to a GPU limitation at 4K. The Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 4070 delivers a broad range of frame rates, from a highly playable 44 FPS at 4K High to a blistering 266 FPS at 1080p Low. This combination of a mobile-class processor with 14 cores and a desktop-class GPU with 12 GB of VRAM creates distinct performance characteristics that are worth examining in detail.

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

The Intel Core Ultra 5 135H is a 14-core, 18-thread processor based on the Meteor Lake architecture, manufactured on Intel's 7 nm process node. Its base clock is 3.60 GHz, with a boost clock of 4.60 GHz, and it carries 18 MB of shared L3 cache. The CPU's TDP is rated at 28 W, indicating a power-efficient mobile design, yet its benchmark scores suggest it is more than capable of feeding the RTX 4070 in a simulation game like Pc Building Simulator. The processor's integrated graphics are Arc Xe-LPG 96EU, though they are not the primary driver here.

Benchmark results place this CPU in the 81st percentile of all processors tested, with an average benchmark score of 29093. Its closest rival, the AMD Ryzen 7 5800X, scores 29123, which is only 0.1% higher, making the performance difference statistically negligible. The Intel Core i5-13500HX scores 29270, placing it 0.6% ahead of the 135H, while the AMD Ryzen 5 5600XT trails by 0.5% with a score of 28940. These numbers indicate that the 135H sits in a tightly contested performance band, and for a simulation game that relies on consistent logic updates, its single-threaded and multi-threaded capabilities are both relevant.

In Pc Building Simulator, the game's simulation loop—tracking component temperatures, power draw, and system stability—is primarily single-threaded. The CPU's Cinebench R23 single-core score of 1700 and Passmark single-thread score of 3521 suggest adequate headroom for these tasks. However, the data shows that at 1080p, the CPU is the limiting factor. At 1080p Low, the system delivers 266 FPS, but at 1080p Ultra, it drops to 127 FPS. This 139 FPS gap across settings is substantial, and since the GPU is not yet saturated at 1080p, the frame rate variation is largely attributed to the CPU's ability to process the game's increased simulation complexity at higher settings. The multi-threaded Cinebench R23 score of 11875.5 confirms the CPU can handle background tasks, but the game's primary thread remains the bottleneck.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core Ultra 5 135H and the NVIDIA GeForce RTX 4070 ranks 1577th out of 3002 tested combos in Pc Building Simulator. This places it squarely in the middle of the pack, which is surprising given the hardware's individual performance. The rank is not a measure of absolute playability but rather a comparative index of how this specific CPU-GPU pairing performs relative to all other pairings tested. Being in the 52nd percentile (1577/3002) suggests that many other combos, likely with stronger desktop CPUs, outperform this mobile-processor-plus-desktop-GPU pairing in this specific title.

The mid-pack ranking is likely due to the CPU's mobile pedigree. While the RTX 4070 is a desktop-class GPU, the 135H is designed for laptops, and its 28 W TDP limits sustained all-core performance. In a game like Pc Building Simulator, where CPU logic is critical, the combo's rank reflects a subtle imbalance. For context, the CPU alone sits at the 81st percentile against all CPUs, and the GPU also sits at the 81st percentile against all GPUs. Yet, when combined, they only reach the 52nd percentile of combos. This discrepancy highlights that the game is highly sensitive to CPU performance, and the 135H, while competent, does not boost the combo into the top tier.

The nearest rival combos for the CPU—such as the AMD Ryzen 7 5800X, which scores within 0.1%—are desktop parts with higher sustained clocks. In a benchmark database, the combo rank is a holistic measure, and the data shows that this pairing is more than capable of smooth gameplay but does not dominate the charts. For players, this rank suggests a balanced experience: not the fastest possible, but far from a weak configuration.

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

The measured FPS data shows a clear pattern of scaling from 1080p to 4K, which reveals the shift in bottleneck from CPU to GPU. At 1080p High, the system delivers 133 FPS. Moving to 1440p High, the frame rate drops to 84 FPS, a 36.8% reduction. Going further to 4K High, the frame rate falls to 44 FPS, another 47.6% drop from 1440p. This degradation is steep but expected, as the pixel count increases from 2.07 million at 1080p to 3.69 million at 1440p and finally to 8.29 million at 4K.

The scaling pattern across settings is revealing. At Low settings, the frame rates are 266 FPS at 1080p, 168 FPS at 1440p, and 88 FPS at 4K. The 1080p-to-1440p drop is 36.8%, and the 1440p-to-4K drop is 47.6%. At Medium settings, the numbers are 189 FPS, 119 FPS, and 62 FPS respectively, with similar percentage drops. This consistent scaling suggests that the GPU is the primary limiter as resolution increases. At 1080p, the CPU is the bottleneck, as evidenced by the massive headroom—266 FPS at Low indicates the GPU is underutilized. At 4K, the GPU is fully saturated, and the frame rates are constrained by the RTX 4070's raw compute.

The data also shows that the gap between Low and Ultra settings narrows at higher resolutions. At 1080p, Ultra is 127 FPS while Low is 266 FPS, a 52.3% difference. At 4K, Ultra is 42 FPS while Low is 88 FPS, a 52.3% difference as well. This parity indicates that the game's settings affect both CPU and GPU load proportionally, but the absolute headroom at 1080p allows the CPU to become the limiting factor, preventing the GPU from reaching its full potential.

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

The measured FPS data provides a complete picture of performance across three resolutions and four settings levels. At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 266 FPS, Medium produces 189 FPS with a minimum of 160 FPS and a maximum of 217 FPS, High produces 133 FPS, and Ultra produces 127 FPS. The Medium setting data includes variance, showing that the game can dip to 160 FPS under load, but overall, the 1080p experience is exceptionally smooth, even at Ultra.

At 2560x1440, the frame rates remain high but show more strain. Low settings deliver 168 FPS, Medium delivers 119 FPS with a minimum of 101 FPS and a maximum of 137 FPS, High delivers 84 FPS, and Ultra delivers 80 FPS. The Medium setting's minimum of 101 FPS is still well above the 60 FPS threshold for smooth gameplay, but the drop from 1080p to 1440p is noticeable. The data suggests that 1440p is the sweet spot for this combo, balancing visual fidelity and performance.

At 3840x2160, the system begins to struggle. Low settings produce 88 FPS, Medium produces 62 FPS with a minimum of 53 FPS and a maximum of 72 FPS, High produces 44 FPS, and Ultra produces 42 FPS. The Medium setting's minimum of 53 FPS is just below the 60 FPS target, indicating that 4K gaming requires settings tuning. The Ultra setting at 42 FPS is playable but not ideal for a simulation game that may require precise timing. The data shows a clear gradient: 1080p is CPU-bound with massive headroom, 1440p is balanced, and 4K is GPU-bound with frame rates dropping to console-like levels.

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

The NVIDIA GeForce RTX 4070 is a desktop GPU based on the Ada Lovelace architecture, utilizing the AD104 chip manufactured on TSMC's 5 nm process. It features 12 GB of GDDR6X memory on a 192-bit bus, providing a memory bandwidth of 504.2 GB/s. The GPU's base clock is 1920 MHz with a boost clock of 2475 MHz, and it has 5888 shading units, 184 texture mapping units, and 64 raster output units. The RTX 4070 also includes 46 ray tracing cores and 184 tensor cores, with a FP32 performance of 29.15 TFLOPS.

The GPU's 12 GB of VRAM is more than sufficient for Pc Building Simulator, which is not a graphically intensive title. The game's textures and models are relatively simple, and the data shows that VRAM capacity is not a limiting factor at any resolution or setting. The GPU's benchmark scores place it in the 81st percentile of all GPUs, with an average score of 37648. Its closest rival, the NVIDIA Tesla P4, scores 37628, a 0.1% difference, while the AMD Radeon RX Vega 56 scores 37507, 0.4% lower. The NVIDIA GeForce RTX 4080 Mobile scores 38135, 1.3% higher, and the AMD Radeon PRO W6400 scores 37157, 1.3% lower.

In this game, the GPU's role becomes dominant at 4K. The data shows that at 1080p, the GPU is not fully utilized, as evidenced by the high frame rates exceeding 200 FPS. At 4K, the GPU is the bottleneck, and the frame rates drop to 44 FPS at High settings. The GPU's raw compute is sufficient for 1440p High at 84 FPS, which is a solid experience. The RTX 4070's memory bandwidth of 504.2 GB/s is ample for the game's data transfer needs, and the 12 GB VRAM ensures no texture swapping occurs even at Ultra settings. The GPU's performance in this title is predictable: it shines at 1080p and 1440p but requires settings reduction at 4K to maintain playable frame rates.
