GPU Role

The NVIDIA GeForce RTX 4090 is the dominant component in this pairing, and the measured FPS data reflects its immense headroom. With 24 GB of GDDR6X memory and a 384-bit bus delivering 1.01 TB/s of bandwidth, the card is built to handle massive texture loads and high-resolution rendering without bottlenecking. Its 16,384 shading units and 176 ROPs are key to the raw pixel throughput seen in Pc Building Simulator, a game that does not demand the same level of GPU complexity as modern shooters.

The RTX 4090's boost clock of 2520 MHz and base clock of 2235 MHz, combined with its 82.58 TFLOPS of FP32 compute, allow it to push frame rates that far exceed typical display refresh rates at lower resolutions. The card's 91st percentile ranking among all GPUs, with an average benchmark score of 66,473, confirms its position near the top of the performance hierarchy. Interestingly, its nearest rivals in the benchmark database are not gaming cards but professional-oriented parts like the NVIDIA Tesla T4 and Tesla P40, which score 66,733 and 66,127 respectively. This suggests that in synthetic tests, the RTX 4090's raw compute is comparable to data-center accelerators, though its gaming-specific features like the 128 RT cores and 512 tensor cores are what drive real-world game performance.

The GPU's 5 nm process node from TSMC, with 76,300 million transistors, provides the efficiency needed to sustain high clocks without immediate thermal throttling. In the context of this simulation game, the 4090 appears to be overkill for most settings, as even at 4K Ultra it maintains an average of 81.5 FPS, which is above the 60 FPS standard for smooth gameplay. The data implies that the GPU is rarely the limiting factor; instead, the CPU or game engine itself may cap performance at lower resolutions.

Resolution Scaling

The measured FPS data reveals a clear scaling pattern as resolution increases from 1920x1080 to 3840x2160. At 1080p Low, the combo achieves an average of 434.3 FPS, which drops to 329.6 FPS at 1440p Low, and further to 169.9 FPS at 4K Low. This represents a 61% reduction in frame rate from 1080p to 4K at Low settings, indicating that the GPU is still heavily utilized even at the lowest quality preset. The scaling is less severe at Ultra settings: 248.7 FPS at 1080p, 155 FPS at 1440p, and 81.5 FPS at 4K, a 67% drop across the resolution range.

The fact that 1080p Low produces over 400 FPS suggests that the CPU is capable of feeding the GPU at extremely high rates, but the game engine or CPU single-thread performance may be approaching a ceiling. The i7-13700K's single-thread score of 1,136 in 3DMark and 5,505 in Cinebench R23 indicates strong per-core performance, yet the gap between 1080p and 1440p at Low (434.3 vs 329.6 FPS) is larger than the gap between 1440p and 4K (329.6 vs 169.9 FPS). This non-linear scaling implies that at 1080p, the CPU is partially limiting the frame rate, while at 4K, the GPU becomes the primary bottleneck.

At Medium settings, the frame rates scale from 369.8 FPS at 1080p to 234.5 FPS at 1440p, and 121.3 FPS at 4K. This shows that the game's render load increases predictably with resolution, but the RTX 4090's 1.01 TB/s bandwidth keeps the memory subsystem from becoming a constraint. The overall pattern suggests that for competitive play at high refresh rates, 1080p or 1440p with Low settings provides the highest headroom, while 4K Ultra is reserved for visual fidelity over raw speed.

Measured FPS Breakdown

At 1920x1080, the measured average FPS across all settings is as follows: Low delivers 434.3 FPS, Medium 369.8 FPS, High 263.1 FPS, and Ultra 248.7 FPS. The difference between High and Ultra is only 14.4 FPS, indicating diminishing returns from the highest preset. This suggests that Ultra's additional effects, such as higher shadow quality or ambient occlusion, are not heavily taxing the RTX 4090's 16,384 shading units.

Moving to 2560x1440, the averages are 329.6 FPS on Low, 234.5 FPS on Medium, 163.8 FPS on High, and 155 FPS on Ultra. The drop from Low to Medium is 95.1 FPS, whereas the drop from Medium to High is 70.7 FPS, and from High to Ultra is only 8.8 FPS. This pattern indicates that the GPU's texture rate of 1,290.2 GTexel/s and pixel rate of 443.5 GPixel/s are more than sufficient for the game's geometry and lighting at 1440p.

At 3840x2160, the averages are 169.9 FPS on Low, 121.3 FPS on Medium, 84 FPS on High, and 81.5 FPS on Ultra. The gap between High and Ultra narrows to just 2.5 FPS, showing that at 4K, the game is likely hitting a memory bandwidth limit or a CPU draw-call bottleneck. The 24 GB VRAM capacity is not a factor here, as the game's textures are unlikely to exceed even 8 GB. The 81.5 FPS at 4K Ultra is still well above the 60 FPS threshold, making this combo a viable 4K gaming solution for this simulation title.

How This Combo Ranks

This CPU-GPU combination ranks 20th out of 1,769 tested combos in Pc Building Simulator, placing it in the top 1.1% of all configurations. The rank is based on the measured FPS across all resolutions and settings, with the i7-13700K and RTX 4090 demonstrating exceptional consistency. The CPU's 93rd percentile ranking among all processors, with an average benchmark score of 47,282, is a strong foundation, but the GPU's 91st percentile is equally critical.

The nearest CPU rivals are the i7-13700KF (delta -0.1%), AMD EPYC 4364P (delta 0.3%), and Intel Core i9-12900F (delta 0.4%). These deltas are minuscule, meaning that swapping the CPU for any of these would likely result in a negligible FPS change in this game. The GPU's nearest rivals include the Tesla T4 (-0.4%) and Tesla P40 (0.5%), but these are not gaming products, so their presence in the benchmark data does not imply competitive gaming performance.

The 20th rank suggests that there are 19 combos that produce higher average FPS, likely featuring newer or more specialized hardware. However, given that Pc Building Simulator is not a graphically demanding title, the rank is more a signal of the raw power of this pairing than to any game-specific optimization. The data indicates that this combo is overkill for the game's requirements, as even the 4K Ultra result of 81.5 FPS is far above the playability threshold.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend on the user's display refresh rate. For a 60 Hz display, 4K Ultra at 81.5 FPS provides the highest visual quality while staying comfortably above the refresh rate. For a 144 Hz display, 1440p High at 163.8 FPS or 4K Medium at 121.3 FPS both offer smooth gameplay, with the latter providing higher resolution at a slight FPS cost.

For 240 Hz displays, 1080p High at 263.1 FPS or 1440p Low at 329.6 FPS are the best choices, as they exceed the refresh rate and minimize input lag. The data shows that Ultra settings at 1080p (248.7 FPS) still exceed 240 Hz, so users with 240 Hz panels can enjoy Ultra without sacrificing frame rate. At 4K, the difference between High (84 FPS) and Ultra (81.5 FPS) is negligible, so Ultra is recommended for the best image quality.

If the goal is maximum FPS for competitive play, 1080p Low at 434.3 FPS is the clear winner, though this sacrifices visual fidelity. The Medium preset at 1080p (369.8 FPS) offers a balance of quality and speed, and it is only 64.5 FPS slower than Low. Given that the game is a simulation, visual clarity for reading text and UI elements is important, so Medium or High at 1440p is a practical recommendation for most users.

CPU Role

The Intel Core i7-13700K, with its 16 cores and 24 threads, provides substantial multi-threaded capability that is largely underutilized in Pc Building Simulator. The CPU's 3DMark scores show strong scaling from 2 threads (2,262) to 16 threads (10,717) and max threads (12,412), indicating that the Raptor Lake architecture handles parallel workloads efficiently. However, the game's simulation logic likely relies more on single-thread performance, where the CPU scores 1,136 in 3DMark and 5,505 in Cinebench R23.

The CPU's base clock of 3.40 GHz and boost clock of 5.40 GHz, combined with a 30 MB shared L3 cache, are sufficient to avoid bottlenecking the RTX 4090 at lower resolutions. The 1080p Low result of 434.3 FPS suggests that the CPU can issue draw calls faster than the GPU can render them, but the 4K Low result of 169.9 FPS indicates that the GPU's render load becomes the limiting factor as pixel count increases.

The CPU's 125 W TDP and support for DDR4 and DDR5 memory give it flexibility, but the game's memory bandwidth requirements are modest. The passmark scores for data compression (595,292) and integer math (154,446) show strong computational throughput, but these are not directly relevant to gaming. In this sim title, the CPU's role is to manage the simulation state and asset loading, and the i7-13700K's 93rd percentile ranking ensures that it handles these tasks without introducing stutter or frame drops. The data implies that a less powerful CPU would still achieve similar FPS at 4K, but the i7-13700K's headroom guarantees consistent performance across all settings.
