Pc Building Simulator

Pc Building Simulator is a unique title where the hardware you are assembling is the star, and the benchmark results for the Intel Core Ultra X9 388H paired with the NVIDIA GeForce RTX 5080 show a system that is overwhelmingly GPU-bound at higher resolutions, but reveals a significant bottleneck at 1080p. The data indicates this combo ranks 725th out of 3002 tested configurations, placing it in the top quarter of all systems measured for this simulation title.

Resolution Scaling

The measured frames per second reveal a predictable but steep curve as resolution increases. At 1920x1080 with Ultra settings, the system delivers an average of 172 FPS, which is exceptionally high for a simulation game. Moving to 2560x1440 drops that average to 109 FPS, a reduction of 63 FPS. The jump to 3840x2160 is even more punishing, with the average falling to 57 FPS on Ultra. This scaling pattern—from 172 to 109 to 57 FPS—shows a roughly 37% performance loss from 1080p to 1440p, and then a further 48% loss from 1440p to 4K.

This steep decline is the classic signature of a GPU-limited scenario. The RTX 5080 is being pushed harder at each step, and the frame rate drops accordingly. However, the data also hints that the CPU is not entirely off the hook. At 1080p Low settings, the system hits 362 FPS, which is a phenomenal number but also suggests that the CPU's 16 cores and 16 threads are reaching their practical limit in this engine. The fact that 1080p Ultra (172 FPS) is only about 53% of the 1080p Low figure (362 FPS) shows that the GPU is still doing substantial work, but the gap between 1080p Low and 1440p Low (228 FPS) is a 134 FPS drop, which is disproportionately large compared to the pixel count increase. This indicates that while the GPU is the primary limiter, the CPU's single-thread performance, as evidenced by its Cinebench R23 single-core score of 2200.5, is a secondary constraint that prevents the system from scaling perfectly with lower graphical loads.

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this pairing. Its 16 GB of GDDR7 memory on a 256-bit bus provides a substantial 960.0 GB/s of bandwidth, which is more than sufficient for a game like Pc Building Simulator that primarily renders 3D models of components. The GPU's 10752 shading units and 112 ROPs handle the visual load at 4K, where the average FPS on Medium settings is 85, with a minimum of 72 and maximum of 97. This shows that even at the most demanding resolution, the card maintains playable frame rates.

The clock speeds are also relevant. With a base clock of 2295 MHz and a boost clock of 2617 MHz, the RTX 5080 has a significant amount of headroom. The benchmark results show that the GPU's average score in 3DMark Steel Nomad DX12 is 8637, placing it in the 87th percentile of all GPUs. This performance level is competitive with the AMD Radeon RX 9070 GRE, which is 2.2% faster in average score, and the AMD Radeon 8060S, which is 0.6% faster. The RTX 5080 sits slightly ahead of the AMD Radeon RX 6750 GRE 12 GB by 0.7%. In this game, the GPU's role is clear: it is the workhorse that scales the rendering load, and its 16 GB VRAM ensures that no texture or model data is being swapped out, even at 4K Ultra, where it still manages an average of 57 FPS.

Settings Recommendations

Based on the measured rows, the optimal experience for this hardware depends heavily on the target resolution. For 3840x2160, the Medium preset is the clear sweet spot. It delivers an average of 85 FPS, which is 25 FPS higher than the High preset's 60 FPS and 28 FPS higher than Ultra's 57 FPS. The minimum FPS of 72 on Medium also ensures that there are no significant stutters, whereas the High and Ultra presets do not have min FPS data recorded, suggesting potential instability or simply that the average is too close to the edge of playability.

At 2560x1440, the High preset is the best choice. It achieves an average of 114 FPS, which is a comfortable margin above the 60 FPS threshold, and it is only 5 FPS behind the Ultra preset's 109 FPS. The Medium preset at 1440p offers 162 FPS, but the visual fidelity reduction is likely not worth the extra frames when the High preset is already so fluid. For 1920x1080, the Ultra preset at 172 FPS is the recommended setting. The GPU has ample headroom to run the game at maximum detail, and the frame rate remains far above any competitive threshold. The data shows that the Low preset at 1080p (362 FPS) is pointless for this combination, as the CPU becomes the limiting factor and the visual quality suffers unnecessarily.

FAQ

Q: Can this system run Pc Building Simulator at 4K with maximum settings?

A: Yes, but just barely. The data shows an average of 57 FPS at 3840x2160 with Ultra settings. It is playable, but the Medium preset at 85 FPS provides a much more comfortable margin and a higher minimum frame rate of 72 FPS.

Q: Is the Intel Core Ultra X9 388H or the NVIDIA GeForce RTX 5080 the main bottleneck?

A: At 4K, the RTX 5080 is the clear limiting component, as frame rates scale down with resolution. At 1080p Low, the CPU becomes the bottleneck, capping performance at 362 FPS. The CPU's average benchmark score of 44466 is 0.2% behind the AMD Ryzen 5 7500X3D, showing it is a capable processor, but the game's engine is heavily dependent on GPU throughput.

Q: What is the performance difference between the Low and Ultra presets at 1440p?

A: The measured average FPS at 2560x1440 is 228 FPS on Low and 109 FPS on Ultra. That is a 119 FPS difference, or about 52% lower performance on the Ultra preset. This large gap confirms that the Ultra preset significantly increases the GPU's workload.

Q: How does the RTX 5080 compare to its closest rival in raw compute performance?

A: The RTX 5080's average benchmark score is 56083. The AMD Radeon RX 9070 GRE is 2.2% faster, and the AMD Radeon 8060S is 0.6% faster. The RTX 5080 is 0.7% faster than the AMD Radeon RX 6750 GRE 12 GB and 2.3% faster than the AMD Radeon Pro W5700X. In this game, these differences are minimal.

Q: Is there a frame rate difference between the High and Ultra settings at 1080p?

A: Yes, the data shows a 9 FPS difference. High settings produce an average of 181 FPS, while Ultra produces 172 FPS. Both are extremely high, so the choice comes down to visual preference.

Q: What does the minimum FPS data tell us about the Medium preset?

A: The Medium preset is the only one with recorded min and max FPS values. At 1080p, the range is 218 to 295 FPS. At 1440p, it is 137 to 186 FPS. At 4K, it is 72 to 97 FPS. This indicates that the Medium preset has a stable frame time distribution, with the 4K minimum of 72 FPS ensuring a consistent experience.

CPU Role

The Intel Core Ultra X9 388H is a mobile-class processor with 16 cores and 16 threads, a configuration that is unusual for a gaming-focused benchmark. Its base clock of 2.10 GHz and boost clock of 5.10 GHz are solid, but the fact that it has no hyper-threading means it relies on raw core count and high clocks. The benchmark data shows a Cinebench R23 multi-core score of 18911 and a single-core score of 2200.5, placing the CPU in the 88th percentile of all processors. Its average benchmark score of 44466 is nearly identical to its closest rival, the AMD Ryzen 5 7500X3D, which is only 0.2% faster. It also edges out the Intel Core i9-13950HX by 0.3% and the AMD Ryzen AI Max 385 by 0.4%.

In Pc Building Simulator, the CPU's role is most evident at lower resolutions. At 1080p Low, the system produces 362 FPS, which is a massive number but also represents the ceiling for this processor in this game. When the GPU load is light, the CPU must feed frames as fast as possible, and its 16 threads are the limiting factor. The L3 cache of 18 MB is shared, and the memory bandwidth of 153.6 GB/s for LPDDR5X is adequate, but the data suggests that the game engine is not heavily multithreaded, as the performance gap between 1080p Low and 1440p Low (362 to 228 FPS) is a 37% drop, which is larger than the 33% increase in pixel count. This inefficiency points to a CPU bottleneck where the processor cannot keep up with the GPU at lower resolutions. However, at 4K, the CPU is not a concern, as the GPU is clearly the limiting component, and the CPU's 16 cores are sufficient to maintain the 57 FPS average on Ultra.
