Pc Building Simulator

Pc Building Simulator is a simulation title where the focus is on assembling and benchmarking virtual systems, making frame rate stability a key metric. The measured data for the Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 5080 Mobile reveals a configuration that scales predictably across resolutions. Across twelve tested scenarios, the average frame rates range from 57 FPS at 4K Ultra to 351 FPS at 1080p Low, demonstrating a dual-bottleneck profile where the GPU becomes dominant at high resolutions, while the CPU holds the reins at lower settings.

Resolution Scaling

The resolution scaling behavior of this combo follows a steep, consistent downward curve. Moving from 1920x1080 to 2560x1440 at High settings, the average FPS drops from 181 to 114, a reduction of 37% (a 67 FPS loss). The subsequent transition from 1440p to 3840x2160 High cuts performance further to 60 FPS, representing a 47% decline (a 54 FPS loss). Cumulatively, the 1080p to 4K High transition removes 121 FPS, or roughly 67% of the frame rate. This scaling profile indicates that the GPU is the primary limiting component as pixel count increases. At Low settings, the trend is even more pronounced: 1080p yields 351 FPS, 1440p yields 228 FPS, and 4K drops to 119 FPS. The relative drop between 1080p and 1440p is 35% (123 FPS), while the drop between 1440p and 4K is 48% (109 FPS). The larger relative loss at 4K suggests that the RTX 5080 Mobile's pixel throughput and memory bandwidth are being heavily taxed, whereas at 1080p the frame rate is so high that the CPU's frame-delivery ceiling becomes apparent. The Medium preset, which is the only row with recorded minimum FPS values, shows a consistent floor across resolutions: 218 at 1080p, 137 at 1440p, and 72 at 4K. These minimums scale almost linearly with resolution, reinforcing that the GPU is the limiting factor in this simulation title as resolution climbs.

GPU Role

The NVIDIA GeForce RTX 5080 Mobile is equipped with 16 GB of GDDR7 VRAM on a 256-bit bus, providing a memory bandwidth of 896.0 GB/s. Its base clock is 975 MHz, with a boost clock of 1500 MHz, and it carries 23.04 TFLOPS of FP32 compute and a pixel rate of 144.0 GPixel/s. In this game, the GPU's dominance becomes obvious at 4K. The Ultra preset produces an average of 57 FPS, which falls below the 60 FPS target, while the Medium preset holds at 85 FPS with a minimum of 72 FPS. The GPU's aggregate benchmark average is 38349, placing it at the 81st percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 4080 Mobile, which scores 0.6% higher on average, and the NVIDIA GeForce MX570, which scores 0.1% higher. These close deltas indicate that the RTX 5080 Mobile sits just below the RTX 4080 Mobile in raw compute, yet in Pc Building Simulator, the 4K Ultra result of 57 FPS confirms that the GPU is not over-provisioned at the highest settings. The 16 GB VRAM capacity is ample for this simulation, and the high 896.0 GB/s bandwidth ensures that texture streaming does not cause frame drops, as evidenced by the stable minimum FPS values on the Medium preset across all resolutions.

Settings Recommendations

The measured FPS data strongly favors the Medium preset as the optimal balance for this combo. At 3840x2160, Medium delivers 85 FPS with a minimum of 72 FPS, while High sits exactly at 60 FPS and Ultra drops to 57 FPS. Since 60 FPS is the standard threshold for smooth gameplay, Medium is the only preset at 4K that provides a comfortable buffer above that line. At 2560x1440, Medium reaches 162 FPS with a minimum of 137 FPS, while Ultra yields 109 FPS. The 53 FPS gap between Medium and Ultra means Medium is better suited for high-refresh displays, though Ultra remains playable. At 1920x1080, Medium produces 256 FPS with a minimum of 218 FPS, while Ultra delivers 172 FPS. The High preset is consistently the weakest of the three non-Low settings, yielding 181 FPS at 1080p, 114 FPS at 1440p, and 60 FPS at 4K. This suggests that the game's High preset does not scale efficiently, while Medium offers the most balanced trade-off between visual quality and frame rate. For users seeking the highest visual fidelity, the Ultra preset at 1440p (109 FPS) is acceptable, but the Medium preset is the recommended choice for a consistently high and stable frame rate across all resolutions.

FAQ

Q: Can this combo achieve 60 FPS at 4K in Pc Building Simulator?

A: Yes, but only at certain settings. At 4K with Medium settings, it achieves an average of 85 FPS with a minimum of 72 FPS. At High settings, it reaches exactly 60 FPS, while at Ultra it drops to 57 FPS, which is below the 60 FPS threshold.

Q: What is the highest average frame rate measured for this combo?

A: The highest recorded average is 351 FPS at 1920x1080 with the Low preset. The Medium preset at 1080p achieves 256 FPS with a minimum of 218 FPS.

How This Combo Ranks

This pairing of the Intel Core Ultra 5 135H and the NVIDIA GeForce RTX 5080 Mobile holds a rank of 966 out of 3723 tested combinations in Pc Building Simulator. This places it in the top 26% of all configurations, meaning it outperforms roughly 74% of the combos in the database. The CPU and GPU both sit at the 81st percentile in their respective aggregate benchmark distributions, which indicates a well-matched pairing. In the context of this simulation title, the rank 966 reflects a system that can handle 4K with Medium settings but falls short of the absolute top tier. The presence of the RTX 4080 Mobile as a close rival (0.6% higher average score) shows that this mobile GPU is near the upper edge of high-performance laptop parts. The combo's rank is respectable, but it is not among the elite configurations that can push 4K Ultra to 60 FPS without compromise.

CPU Role

The Intel Core Ultra 5 135H is a mobile processor with 14 cores and 18 threads, operating at a base clock of 3.60 GHz and a boost clock of 4.60 GHz. Its TDP is 28 W, and it features 18 MB of shared L3 cache. In synthetic benchmarks, it scores 11875.5 in Cinebench R23 multi-core and 1700 in single-core, with an average benchmark score of 29093 and an 81st percentile ranking. Its nearest rivals include the AMD Ryzen 7 5800X, which has a delta of -0.1%, and the Intel Core i5-13500HX, which has a delta of -0.6%. The near-identical scores to these desktop and high-end mobile parts indicate that the 135H provides strong multithreaded performance. In this game, the CPU is capable of pushing the GPU to 351 FPS at 1080p Low, demonstrating that it does not bottleneck the system at moderate settings. The 4.60 GHz boost clock ensures that the game's main simulation thread remains responsive, while the 18 threads help with background system logic. The CPU's launch MSRP is $342.
