# Pc Building Simulator with Intel Core Ultra 5 135H + NVIDIA GeForce RTX 4090

The Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 4090 delivers an unusual performance profile in Pc Building Simulator, a simulation title that leans heavily on CPU throughput. This combo ranks 663rd out of 3,002 tested combinations, placing it in the top 22% of all configurations. The data reveals a system that scales dramatically with resolution changes but behaves unexpectedly at lower settings, suggesting the game's workload distribution favors certain hardware characteristics over raw graphics muscle.

Resolution Scaling

The measured FPS data shows a consistent and steep decline as resolution increases, which is typical for a GPU-bound scenario—but the magnitude here is noteworthy. At 1080p with Low settings, the combo achieves 351 FPS average. Moving to 1440p Low drops that to 233 FPS, a reduction of 118 FPS (roughly 34% lower). At 4K Low, the average falls to 122 FPS, which is 65% below the 1080p Low figure. This scaling pattern indicates that even at the lowest settings, the RTX 4090's rendering workload grows substantially with pixel count, and the CPU has enough headroom to keep feeding frames.

The High preset tells a similar story but with a different slope. At 1080p High, the average is 185 FPS; at 1440p High, it drops to 117 FPS; and at 4K High, it reaches just 61 FPS. The gap between 1080p and 1440p High is 68 FPS, while the gap between 1440p and 4K High is 56 FPS. This near-linear decline suggests that the game's visual complexity at High settings imposes a fairly consistent per-pixel cost, with the GPU becoming the limiting factor well before 4K.

Medium settings offer the only complete min/max data in the pack, providing insight into frame pacing. At 1080p Medium, the average is 262 FPS with a minimum of 222 and maximum of 301. At 1440p Medium, the average drops to 165 FPS with a range of 140 to 190. At 4K Medium, the average is 86 FPS with a range of 73 to 99. The spread between min and max narrows as resolution rises—79 FPS at 1080p, 50 FPS at 1440p, and 26 FPS at 4K—indicating that lower resolutions expose more CPU-driven variance, while higher resolutions smooth out frame delivery due to GPU saturation.

Ultra settings produce the lowest averages across the board: 176 FPS at 1080p, 111 FPS at 1440p, and 58 FPS at 4K. The 4K Ultra result of 58 FPS is just shy of the 60 FPS threshold that many users target, and it represents a 67% drop from the 1080p Ultra figure. Notably, the difference between High and Ultra at 4K is only 3 FPS (61 vs. 58), while at 1080p the difference is 9 FPS (185 vs. 176). This convergence at 4K suggests that the GPU's pixel throughput ceiling is being approached regardless of quality preset, making the visual settings less impactful at extreme resolutions.

How This Combo Ranks

With a combo rank of 663 out of 3,002 tested configurations, this pairing sits comfortably in the upper quartile of all combinations. The rank reflects the aggregate performance across the game's benchmark scenarios, and the data indicates that the RTX 4090's massive compute resources are partially held back by the Intel Core Ultra 5 135H's mobile-oriented design. The CPU's 14 cores and 18 threads provide solid multithreaded capability, but its 28 W TDP and BGA 2049 socket highlight its laptop pedigree.

The CPU's benchmark scores contextualize its role. In Cinebench R23, it scores 11,875.5 in multicore and 1,700 in single-core. These figures place it in the 81st percentile of all CPUs, with an average benchmark score of 29,093. Its nearest rival, the AMD Ryzen 7 5800X, scores 29,123, a delta of -0.1%, meaning the two are effectively tied. The Intel Xeon Phi 7210 is 0.5% ahead, while the AMD Ryzen 5 5600XT is 0.5% behind. This tight clustering suggests the Core Ultra 5 135H delivers desktop-class compute in a mobile package, which is critical for a simulation game that likely benefits from CPU cache and thread scheduling.

The GPU, meanwhile, ranks in the 88th percentile of all GPUs with an average benchmark score of 60,347. Its closest rival, the Intel Arc Pro A60, scores 60,326 (0% delta), while the AMD Radeon Pro Vega 48 is 0.3% behind. This places the RTX 4090 in rarefied air, but the combo rank of 663rd out of 3,002—rather than higher—indicates that the game's engine does not fully utilize the GPU's capabilities. The gap between the GPU's elite percentile and the combo's mid-top-quartile rank suggests a CPU bottleneck in certain scenarios, particularly at lower resolutions where the CPU must feed frames faster.

Settings Recommendations

Based on the measured FPS rows, the Medium preset at 1440p offers the best balance of visual fidelity and frame rate. The 165 FPS average with a minimum of 140 and maximum of 190 provides a smooth experience that exceeds the refresh rate of most high-end monitors, and the min/max spread of 50 FPS indicates consistent frame delivery. Pushing to High at 1440p drops the average to 117 FPS, which is still playable but introduces more variability in demanding scenes.

For 4K users, Medium is the pragmatic choice. The 86 FPS average at 4K Medium is well above the 60 FPS threshold, and the tight 73-to-99 FPS range ensures no major hitches. High at 4K drops to 61 FPS, which is borderline for users sensitive to frame drops, and Ultra at 4K falls to 58 FPS, which may be perceptibly less smooth. The data shows that the step from Medium to High at 4K costs 25 FPS, while High to Ultra costs only 3 FPS—so the visual quality gains from Ultra are not worth the performance sacrifice.

At 1080p, the choice depends on whether users prioritize maximum frame rates or visual quality. Low settings deliver 351 FPS, which is excessive for most displays but useful for competitive play or high-refresh-rate panels. Medium at 262 FPS offers a 74% improvement over High's 185 FPS, and the 222-to-301 FPS range is smooth. For most users, Medium at 1080p is the sweet spot, as it provides a substantial frame rate buffer while maintaining acceptable visuals. Ultra at 1080p yields 176 FPS, which is still high but represents a 33% drop from Medium—a poor trade for marginal visual gains in a simulation game where textures and UI clarity matter more than particle effects.

Measured FPS Breakdown

At 1920x1080, the measured averages span from 176 FPS at Ultra to 351 FPS at Low. The full progression is: Low 351, Medium 262 (min 222, max 301), High 185, Ultra 176. The jump from Low to Medium is 89 FPS, while Medium to High costs 77 FPS, and High to Ultra costs just 9 FPS. This suggests that the High-to-Ultra transition is nearly free in terms of performance, making Ultra a reasonable choice if the visual difference is meaningful to the user.

At 2560x1440, the averages are: Low 233, Medium 165 (min 140, max 190), High 117, Ultra 111. The Low-to-Medium drop is 68 FPS, Medium-to-High is 48 FPS, and High-to-Ultra is 6 FPS. The pattern mirrors 1080p but with steeper absolute declines, as the pixel count increases by 78% from 1080p to 1440p. The min/max data at Medium shows a spread of 50 FPS, which is proportionally similar to the 79 FPS spread at 1080p when adjusted for the lower average.

At 3840x2160, the averages are: Low 122, Medium 86 (min 73, max 99), High 61, Ultra 58. The Low-to-Medium drop is 36 FPS, Medium-to-High is 25 FPS, and High-to-Ultra is 3 FPS. The 4K results show a compression of frame rates at the high end, where the GPU's pixel fill rate becomes the dominant constraint. The Medium min/max spread of 26 FPS is the tightest of any resolution, indicating that frame pacing stabilizes when the GPU is fully loaded. The 4K Low average of 122 FPS is notable—it exceeds the High preset at 1440p (117 FPS), which shows that resolution has a larger impact on performance than quality settings in this game.

GPU Role

The NVIDIA GeForce RTX 4090 brings formidable specifications to this pairing, including 24 GB of GDDR6X memory on a 384-bit bus with 1.01 TB/s of bandwidth. The memory clock runs at 1313 MHz (21 Gbps effective), and the GPU operates at a base clock of 2235 MHz with a boost of 2520 MHz. The AD102 chip contains 16,384 shading units, 512 TMUs, and 176 ROPs, with 128 RT cores and 512 tensor cores. These figures translate to 82.58 TFLOPS of FP32 compute and a pixel rate of 443.5 GPixel/s.

The 24 GB frame buffer is particularly relevant for Pc Building Simulator, which may load large textures for component models and workshop environments. The GPU's 88th percentile ranking and average benchmark score of 60,347 place it well above the median, but the measured FPS data shows that the RTX 4090 is not the limiting factor in most scenarios. At 1080p Low, the 351 FPS average suggests the CPU is the bottleneck, as the GPU could theoretically render far more frames with its compute headroom.

The RTX 4090's process node of 5 nm at TSMC and 76,300 million transistors on a 609 mm² die indicate a high transistor density of 125.3M per mm². This architectural efficiency is evident in the 4K Medium result of 86 FPS, which maintains a playable frame rate despite the 8.3 million pixels being rendered per frame. The GPU's 1.01 TB/s bandwidth ensures that texture streaming keeps pace with the rendering pipeline, even when the simulation spawns numerous 3D objects with high-resolution materials.

The GPU's nearest rival in benchmark scores, the Intel Arc Pro A60, is essentially tied at 0% delta, but the RTX 4090's real-world gaming performance is likely superior due to driver maturity and feature set. The measured data supports this—the RTX 4090's 4K Ultra average of 58 FPS, while not ideal, still represents playable performance in a simulation genre where exact frame rates matter less than in fast-paced shooters.
