Pc Building Simulator

Pc Building Simulator, a simulation title focused on PC assembly and repair, presents a distinctive workload that scales in unexpected ways across resolutions and settings. The measured data for the Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 4070 Mobile reveals a configuration that is remarkably balanced, though its behavior shifts decisively depending on the chosen resolution. This analysis walks through the measured FPS numbers to interpret what they say about the hardware's strengths and limitations in this specific game.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and tells a clear story about where the bottleneck lies. Moving from 1920x1080 to 2560x1440 at High settings, the average frame rate falls from 133 FPS to 84 FPS, a reduction of 49 FPS or roughly 37%. The jump from 1440p to 4K is comparatively smaller in absolute terms, dropping from 84 FPS to 44 FPS at High settings, a 40 FPS decrease. This pattern — a large absolute drop from 1080p to 1440p followed by a further drop to 4K — indicates that the GPU is the primary limiting component across all resolutions, but the nature of the workload shifts.

At 1080p, the system produces very high frame rates, with Low settings hitting 266 FPS. This suggests the CPU is capable of feeding the GPU well enough to avoid a severe bottleneck, but the sheer volume of frames at this resolution puts pressure on the processor. The gap between Low and Ultra at 1080p is 139 FPS (266 vs 127), which is a massive spread that shows how much headroom exists when the GPU is less stressed. At 4K, the gap between Low and Ultra is only 46 FPS (88 vs 42), a much tighter range that points to the GPU being fully saturated. The data shows that as resolution increases, the frame rate becomes more constrained by the GPU's rendering limits, not by the CPU or memory subsystem.

The scaling from Medium to High to Ultra is consistent across all resolutions, with each step up in quality costing about 20-25% of the previous frame rate. At 1080p, Medium delivers 189 FPS, High drops to 133 FPS, and Ultra falls to 127 FPS. At 1440p, the same progression yields 119, 84, and 80 FPS. At 4K, the numbers are 62, 44, and 42 FPS. The relatively small gap between High and Ultra at each resolution (6-7 FPS at 1080p, 4 FPS at 1440p, 2 FPS at 4K) suggests that Ultra settings introduce effects that are more visually demanding than performance-relevant, allowing High to be a sweet spot for frame rate without a major visual compromise.

What the data does not show is any indication of a CPU bottleneck at higher resolutions. If the Core Ultra 5 135H were limiting performance, the frame rates at 4K would cluster together regardless of settings. Instead, the 4K spread from 42 to 88 FPS across the four presets demonstrates that the GPU is the deciding factor. The 135H, with its 14 cores and 18 threads, provides enough processing power to keep the simulation logic running smoothly, even when the GPU is struggling to maintain playable frame rates.

GPU Role

The NVIDIA GeForce RTX 4070 Mobile is the driving force behind these results, and its specifications explain the observed scaling. This GPU features 8 GB of GDDR6 memory on a 128-bit bus, delivering 256.0 GB/s of bandwidth. In a game like Pc Building Simulator, which involves rendering detailed 3D models of components and a workshop environment, memory bandwidth is critical for texture streaming and scene complexity. The 256.0 GB/s figure is adequate for 1080p and 1440p, where the measured frame rates are high, but at 4K with 3840x2160 pixels, the memory subsystem may struggle to keep up with the data demands, contributing to the lower average FPS.

The GPU's clock speeds are modest for a mobile part: a base clock of 1395 MHz and a boost clock of 1695 MHz. These clocks are not particularly high, but the Ada Lovelace architecture compensates with efficiency. The 4608 shading units and 144 texture mapping units provide substantial raw compute power, reflected in the FP32 performance of 15.62 TFLOPS. In Pc Building Simulator, which is not a graphically intense title compared to AAA shooters, this compute power is more than sufficient for the physics and rendering tasks involved. The benchmark scores corroborate this: the GPU achieves a Passmark G3D score of 19587 and a Geekbench OpenCL score of 109197, placing it in the 73rd percentile among all GPUs.

The GPU's nearest rivals in aggregate benchmark scores are telling. The AMD Radeon RX 6700 XT scores 27425, which is 0% different from the RTX 4070 Mobile's 27435. The NVIDIA GeForce RTX 3090 scores 27565, putting the mobile 4070 just 0.5% behind a desktop flagship from the previous generation. This suggests that the RTX 4070 Mobile performs at a level comparable to high-end desktop GPUs from recent years, which aligns with its strong measured performance in this game. The RTX PRO 4000 Blackwell is 1.1% ahead, and the AMD Radeon Pro Vega 20 is 1.5% behind, but these are niche workstation parts, not direct gaming competitors.

In the context of Pc Building Simulator, the GPU's role is to handle the rendering of the workshop, the components on the bench, and the user interface. The measured data shows that at 1080p, the GPU is rarely the bottleneck, as frame rates exceed 127 FPS even at Ultra settings. At 4K, the GPU becomes the clear limiting factor, with the 44 FPS average at High settings being just above the threshold for smooth gameplay. The 8 GB VRAM is sufficient for this game at all tested settings, as no out-of-memory issues are evident in the frame rate data, but the 128-bit memory bus may be a constraint at higher resolutions.

CPU Role

The Intel Core Ultra 5 135H is a mobile processor with 14 cores and 18 threads, based on the Meteor Lake architecture. Its base clock is 3.60 GHz, boosting to 4.60 GHz, with a TDP of 28 W. These specifications position it as a mid-range mobile CPU, and its benchmark scores reflect a capable but not exceptional processor. The Cinebench R23 multi-core score is 11875.5, and the single-core score is 1700, placing it in the 81st percentile among all CPUs. Its nearest rival, the AMD Ryzen 7 5800X, has an average score of 29123, which is just 0.1% higher, indicating the 135H is competitive with desktop CPUs from a few generations ago.

In Pc Building Simulator, the CPU handles the simulation logic — tracking component temperatures, power draw, and system stability as the player builds and modifies PCs. This is a moderately demanding task that benefits from multi-core performance. The 135H's 18 threads provide ample parallelism for these background calculations. The measured FPS data shows that at 1080p, where the GPU is less stressed, the frame rates are high enough (266 FPS at Low) to suggest the CPU is not holding back the system. If the CPU were a bottleneck, the frame rates would plateau at a lower value regardless of GPU load.

The CPU's memory support is DDR5 with a dual-channel bus, providing 89.6 GB/s of bandwidth. This is sufficient for feeding the GPU and handling the game's data streams. The 18 MB of shared L3 cache helps with frequently accessed data, reducing latency in simulation loops. The Passmark multi-thread score of 22422 and the single-thread score of 3521 indicate balanced performance across both lightly and heavily threaded workloads. In a game that may not use all 18 threads effectively, the single-thread performance becomes crucial, and the 3521 score is respectable for a mobile part.

The comparison to the Intel Core i5-13500HX is instructive. That CPU has an average score of 29270, which is 0.6% higher than the 135H's 29093. The i5-13500HX is a higher-TDP part, but the performance difference in synthetic benchmarks is minimal. In Pc Building Simulator, the measured frame rates would likely be nearly identical between these two CPUs, as the game's simulation load does not appear to scale strongly with additional cores. The 135H's boost clock of 4.60 GHz ensures that single-threaded tasks, such as UI interactions and some game logic, are handled promptly.

Settings Recommendations

The measured data provides clear guidance on which settings preset offers the best balance of visual quality and frame rate for this configuration. At 1920x1080, the High preset delivers 133 FPS, which is well above the 60 FPS threshold for smooth gameplay and close to the 144 Hz refresh rate of many gaming monitors. The Ultra preset only drops to 127 FPS, a difference of 6 FPS that is unlikely to be noticeable in a simulation game. For users with high refresh rate displays, Ultra at 1080p is the best choice, as it provides the highest visual fidelity without sacrificing playability.

At 2560x1440, the High preset produces 84 FPS, which is smooth but not ideal for competitive play. The Ultra preset drops to 80 FPS, a 4 FPS difference that is negligible. Given that the gap between High and Ultra is small, choosing Ultra at 1440p is reasonable if visual quality is a priority. However, the Medium preset at 119 FPS offers a significant frame rate advantage over High (35 FPS more) and may be preferable for users who want higher refresh rates. The data suggests that Medium at 1440p is the sweet spot for a 120 Hz display, while High or Ultra is better for 60 Hz panels.

At 3840x2160, the situation changes dramatically. The High preset averages 44 FPS, which is below the 60 FPS target for smooth gameplay and may feel stuttery in a simulation where precise mouse control is needed. The Medium preset at 62 FPS is the only option that meets the 60 FPS threshold, with a minimum FPS of 53 and a maximum of 72. The Ultra preset at 42 FPS is not recommended, as it falls below playable levels. For 4K gaming, the Medium preset is the clear choice, as it provides the best frame rate while maintaining acceptable visual quality. The Low preset at 88 FPS is an option for users who prioritize frame rate over visuals, but the drop in fidelity is substantial.

Across all resolutions, the High preset offers a balanced experience, but the recommendation varies by target resolution. At 1080p, Ultra is viable. At 1440p, High or Ultra works well. At 4K, Medium is the only sensible choice. The data shows that this configuration is best suited for 1080p and 1440p gaming, with 4K requiring compromises on settings.

This places it in the 46th percentile of all tested combos, meaning it performs better than roughly 46% of configurations while being outperformed by the other 54%. This mid-pack ranking is somewhat surprising given the strong individual benchmark scores of both components, but it reflects the fact that Pc Building Simulator is not a demanding title, and many lower-end combinations can achieve high frame rates.

The ranking suggests that while this combo is capable of running the game well at most resolutions and settings, it is not an exceptional performer in this specific title. The 73rd percentile GPU ranking and 81st percentile CPU ranking indicate that both components are above average individually, but the game's low system requirements mean that even mid-range hardware can achieve comparable results. The 2006th rank out of 3723 combos implies that there are many configurations with similar or better performance, likely including those with faster desktop GPUs or CPUs with higher single-thread performance.

The data shows that this combo's strengths lie in its balance. It can handle 1080p and 1440p gaming with high frame rates, and it can manage 4K at Medium settings. However, for a game like Pc Building Simulator, which is not GPU-intensive, the RTX 4070 Mobile's power is somewhat underutilized. The ranking reflects this — the combo is not a top performer because the game does not require top-tier hardware to run smoothly. Users with this configuration will have a positive experience, but they are not getting the best possible performance in this title compared to other tested combos. The mid-pack ranking is a fair assessment of its capabilities in Pc Building Simulator, where the bottleneck is rarely the hardware, but rather the game's own optimization and the limits of the simulation engine.
