Pc Building Simulator

Pc Building Simulator is a simulation title that tasks players with assembling and benchmarking virtual hardware, and the measured performance of the Intel Core Ultra 7 265HX paired with the NVIDIA GeForce RTX 5070 reveals a system that is heavily skewed toward high refresh rate 1080p and 1440p gaming, while 4K proves to be a significant challenge. The data shows a clear hierarchy where the GPU becomes the primary bottleneck at higher resolutions, while the CPU's substantial core count ensures it is rarely the limiting factor in this particular workload.

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

The Intel Core Ultra 7 265HX is a mobile processor built on the Arrow Lake-HX architecture, utilizing a 3 nm process from TSMC. It packs 20 cores and 20 threads, which is a high count for a mobile chip, and it operates with a base clock of 2.60 GHz and a boost clock of 5.30 GHz. This combination of high core count and high boost clock is reflected in its benchmark scores, such as a Cinebench R23 multi-core score of 40642 and a single-core score of 5737, placing it in the 93rd percentile of all CPUs.

In the context of Pc Building Simulator, the CPU's role is less about real-time physics or complex AI and more about simulating the system's components efficiently. The game's logic, inventory management, and the math behind component compatibility can benefit from strong single-thread performance. The PassMark single-thread score of 4500 and the Cinebench R23 single-core score of 5737 indicate that the 265HX has excellent per-core capability, which is crucial for the game's UI and simulation tick rate. The multi-core performance, evidenced by a PassMark multithread score of 47985, ensures that background tasks and the simulation's internal calculations do not cause stutters.

The data suggests that the CPU is more than adequate for this game. When looking at nearest rivals, the 265HX performs nearly identically to the Intel Core i7-13790F, with a delta of just 0.1% in average benchmark score, and is 0.2% behind the AMD Ryzen AI 7 450G. This puts the 265HX in a performance tier where it is unlikely to be the bottleneck in any of the measured FPS scenarios. The 30 MB of shared L3 cache and 102.4 GB/s memory bandwidth provide a solid foundation for feeding the GPU, but the benchmark results indicate that the CPU's headroom is not fully utilized in this title, as FPS scales almost exclusively with resolution and GPU load.

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

The NVIDIA GeForce RTX 5070 is the clear driver of frame rates in this combination. It features 12 GB of GDDR7 memory on a 192-bit bus, providing a bandwidth of 672.0 GB/s. The GPU's base clock is 2325 MHz with a boost clock of 2512 MHz. Its PassMark G3D score is 29137, and it sits in the 82nd percentile of all GPUs. The architecture is Blackwell 2.0, built on a 5 nm process from TSMC, with 6144 shading units.

The GPU's role in Pc Building Simulator is primarily about rendering the 3D workspace, the components, and the case. The measured FPS data shows a direct correlation between GPU load and settings. At 1080p with Low settings, the system achieves 262 FPS, which is exceptionally high. As resolution and settings increase, the frame rate drops, indicating that the RTX 5070 is being pushed harder. The 12 GB VRAM is a notable factor; while the game may not require huge amounts of memory at 1080p, the transition to 4K Ultra settings could see VRAM usage increase, though the data does not provide direct VRAM utilization metrics.

Comparing the RTX 5070 to its nearest rivals shows it is in a unique position. It is 0.1% ahead of the AMD Radeon Pro 580 and 0.8% ahead of the Radeon Pro WX 7100, but 1.2% behind the Radeon Pro 5300. This suggests that within its performance class, the RTX 5070 is a competent but not dominant card. However, in this specific game, the FPS figures at 1440p and 1080p are strong enough to suggest that the GPU has ample compute power for the simulation's rendering demands, and the bottleneck only becomes apparent when targeting 4K.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's capabilities across three resolutions and four settings tiers. At 1920x1080, the system demonstrates its peak performance. Low settings deliver an average of 262 FPS, which is exceptionally fluid. Medium settings reduce the average to 186 FPS, with a minimum of 158 FPS and a maximum of 214 FPS. High settings bring the average down to 131 FPS, and Ultra settings settle at 125 FPS. The close gap between High and Ultra (131 vs 125 FPS) suggests diminishing returns at this resolution.

Moving to 2560x1440, the frame rates scale down predictably. Low settings still provide a high 165 FPS average. Medium settings produce an average of 117 FPS, with a range of 100 to 135 FPS. High settings yield 83 FPS, and Ultra settings drop to 79 FPS. The difference between High and Ultra at 1440p is minimal (4 FPS), indicating that the Ultra preset's additional effects are not heavily taxing the GPU at this resolution.

At 3840x2160, the GPU's limits become apparent. Low settings average 86 FPS, which is playable, but Medium settings fall to 61 FPS, with a minimum of 52 FPS and a maximum of 70 FPS. High settings average 43 FPS, and Ultra settings average 41 FPS. The 4K results show a significant drop from 1440p, with the High preset halving from 83 FPS to 43 FPS, and the Ultra preset falling from 79 FPS to 41 FPS.

Resolution Scaling

Resolution scaling reveals the nature of the bottleneck in this system. From 1080p to 1440p, the average FPS across all settings drops by roughly 37% (e.g., from 131 to 83 FPS on High). This is a substantial decrease, but the frame rates remain high. The drop from 1440p to 4K is more severe. For High settings, the FPS falls from 83 to 43, a 48% reduction. For Ultra settings, it falls from 79 to 41, a 48% reduction as well.

This scaling pattern strongly suggests that the system is GPU-bound at higher resolutions. The CPU's performance does not change with resolution, so if the CPU were the bottleneck, the FPS would stay relatively flat. Instead, the FPS drops are directly proportional to the increase in pixel count, which is a classic sign of the GPU reaching its fill rate and shading limits. The 4K data points, with Ultra and High both hovering around 41-43 FPS, indicate that the RTX 5070's 12 GB VRAM and 192-bit memory bus are likely overwhelmed by the 4K frame buffer and texture loads, rather than the compute cores being the sole limitation.

The data also implies that the CPU has significant headroom. At 1080p Low, the system reaches 262 FPS, which is a high frame rate that requires strong single-thread performance to avoid bottlenecking. The fact that the FPS can reach such levels indicates that the CPU is capable of feeding the GPU at these rates, and the subsequent FPS drops at higher resolutions are not due to CPU stalls.

Settings Recommendations

Based on the measured rows, the optimal experience depends on the target resolution. At 1920x1080, the Medium preset offers an excellent balance, providing an average of 186 FPS with a minimum of 158 FPS. This ensures smooth gameplay while maintaining a reasonable visual quality. The High preset at 131 FPS is also viable, and the Ultra preset at 125 FPS is acceptable, but the 6 FPS gain from High to Ultra is negligible.

For 2560x1440, the High preset is the best choice. It delivers an average of 83 FPS, which is above the 60 FPS threshold for smooth play, and the Ultra preset's 79 FPS does not offer a significant visual upgrade for the 4 FPS loss. The Medium preset at 117 FPS is also a strong option for users who prioritize frame rate over visual fidelity.

At 3840x2160, the data suggests that the Medium preset is the highest playable option, with an average of 61 FPS and a minimum of 52 FPS. The High and Ultra presets, at 43 and 41 FPS respectively, are borderline playable but may feel sluggish. For a better 4K experience, users would need to reduce to Low settings (86 FPS), but this sacrifices visual quality. The data indicates that the Ultra preset is not recommended at 4K, as it provides no benefit over High and only a marginal difference from the lower presets.

How This Combo Ranks

In the grand scheme of benchmark data, this combination of the Intel Core Ultra 7 265HX and NVIDIA GeForce RTX 5070 ranks 1612 out of 3002 tested combos in Pc Building Simulator. This places it in the 46th percentile, meaning it performs better than just under half of all tested systems. This rank is somewhat surprising given the high component scores, but it reflects the specific demands of this simulation game.

The CPU's rank is in the 93rd percentile of all CPUs, which is excellent, and the GPU is in the 82nd percentile. However, the combo rank is much lower, indicating that the pairing is not optimized for this specific title's workload. The data suggests that while each component is individually strong, the game may not be able to fully utilize the CPU's 20-core configuration, and the GPU's 12 GB VRAM might be a limiting factor in certain scenarios.

The nearest rival combos are not listed in the data, but the individual component rivals provide context. The CPU is essentially tied with the Intel Core i7-13790F, and the GPU is slightly behind the AMD Radeon Pro 5300. This means that a combo with a 13790F and a Radeon Pro 5300 might perform similarly, but the lack of specific combo data prevents a direct comparison. The rank of 1612 out of 3002 suggests that this is a mid-tier combo for this game, capable of high FPS at 1080p and 1440p, but not a top-tier performer at 4K.
