# Pc Building Simulator with Intel Core i7-12700K + NVIDIA GeForce RTX 4090

The measured frame rates for this combination reveal a system that is overwhelmingly GPU-bound at higher resolutions but transitions to CPU-bound behavior at 1080p. Across all tested settings, the RTX 4090 delivers exceptional headroom, with the i7-12700K providing sufficient single-thread and multi-thread performance to keep pace in a simulation title that heavily emphasizes component logic and system management. The data shows a clear stratification between preset tiers, with each step from Low to Ultra producing predictable FPS deltas that inform how users should configure the game for their display and preference.

Settings Recommendations

The benchmark data measured across four presets at three resolutions shows that the High preset offers the most balanced experience, though the choice depends heavily on target refresh rate. At 1920x1080, High produces 261.1 FPS average, which is only 13.7 FPS below Ultra’s 247.4 FPS but significantly ahead of Medium’s 354 FPS. However, the most striking observation is that Low at 1080p reaches 401.4 FPS, indicating the CPU becomes the limiting factor at this resolution. For users with 144Hz or 165Hz displays, the Medium preset at 1080p (354 FPS) provides ample headroom while maintaining better visual fidelity than Low.

At 2560x1440, High delivers 161.5 FPS average, which comfortably exceeds 144Hz refresh rates and stays within 3.1 FPS of Ultra’s 158.4 FPS. The Medium preset at 234.7 FPS offers substantial overhead for competitive play, but the visual improvements from High are minimal relative to the FPS cost. For 4K displays, the High preset at 84 FPS average is the recommended starting point, as Ultra drops to 82.8 FPS—a negligible 1.2 FPS difference that does not justify the additional rendering load. The Low preset at 4K (175.2 FPS) is impractical for most users, as it sacrifices visual quality for frame rates that exceed typical 4K display capabilities.

The data indicates that High settings provide the optimal quality-to-performance ratio across all three resolutions, with the 1440p High result (161.5 FPS) serving as the sweet spot for high-refresh-rate gaming. Users targeting 240Hz at 1080p should consider Medium (354 FPS) or Low (401.4 FPS), but the marginal FPS gains beyond Medium come with substantial visual degradation.

CPU Role

The Intel Core i7-12700K features 12 cores and 20 threads based on the Alder Lake architecture, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. This hybrid design combines performance and efficiency cores, and the benchmark scores reflect strong multi-threaded capability: Cinebench R23 multicore reaches 29,241 points, while the single-core score of 4,128 points indicates excellent per-thread performance. The Geekbench results corroborate this, with a multicore score of 13,892 and a single-core score of 2,561.

In Pc Building Simulator, the CPU’s role becomes evident when examining the 1080p results. At Low settings, the average FPS of 401.4 represents the upper bound of what this combination can achieve, and the gap between Low and Medium (354 FPS) is 47.4 FPS—a smaller relative difference than at higher resolutions. This compression suggests that at 1080p, the game’s simulation logic and component interaction calculations become the bottleneck, rather than GPU rendering. The 3DMark scores reinforce this: the 16-thread score of 9,276 and max-thread score of 9,979 indicate that the CPU can handle substantial parallel workloads, but the single-thread score of 1,043 shows that some game logic may be serialized.

The PassMark multithread score of 34,404 places this CPU in the 89th percentile versus all CPUs, with nearest rivals including the AMD Ryzen 7 PRO 5845 (deltaPct -0.3), Intel Core i7-13700T (deltaPct 0.6), Intel Core i5-14500HX (deltaPct -0.7), and Intel Core i7-13800H (deltaPct 0.8). These tiny deltas—all within 0.8%—indicate that the i7-12700K is firmly in a performance cluster where small architectural differences do not translate into meaningful FPS changes in this game. At 4K resolutions, the CPU’s influence diminishes further, as the GPU becomes the primary constraint, evidenced by the FPS scaling from 1080p to 4K at each preset.

FAQ

How This Combo Ranks

The combination of the Intel Core i7-12700K and NVIDIA GeForce RTX 4090 ranks 26th out of 1,769 tested combos in Pc Building Simulator. This places it in the top 1.5% of all configurations, which is consistent with the individual component standings: the CPU sits in the 89th percentile against all CPUs, while the GPU ranks in the 91st percentile against all GPUs. The rank of 26 suggests that there are 25 combinations that achieve higher average FPS in this game, likely featuring newer or more specialized hardware.

The data shows that this combo’s performance is not limited by either component in isolation but rather by the game’s engine characteristics. The 4K Ultra result of 82.8 FPS is respectable but not class-leading, indicating that the simulation workload benefits from certain architectural features that the Alder Lake and Ada Lovelace combination may not fully exploit. The nearest CPU rivals—all within 0.8% in average benchmark score—suggest that swapping the i7-12700K for a Ryzen 7 PRO 5845 or i7-13700T would yield nearly identical in-game results, reinforcing that the combo’s rank is driven more by GPU capabilities than CPU choice.

At 1080p, the combo’s rank is likely higher due to the CPU’s strong single-thread performance (Cinebench R23 single-core score of 4,128), but the 1440p and 4K results are more dependent on the RTX 4090’s raw throughput. The GPU’s PassMark G3D score of 38,194 and 3DMark Steel Nomad DX12 score of 9,223 demonstrate robust rendering capability that translates to the 84 FPS average at 4K High. For users prioritizing this game, the combo’s rank indicates it is a top-tier configuration, though the 25 higher-ranked combos likely employ CPUs with higher multi-thread scores or newer GPU architectures.

Resolution Scaling

The measured FPS data reveals distinct scaling patterns that identify the limiting component at each resolution. From 1080p to 1440p, the average FPS drop across presets is substantial: at High settings, the drop is from 261.1 to 161.5 FPS (a 38.1% reduction), while at Low settings, the drop is from 401.4 to 329.8 FPS (a 17.8% reduction). This disproportionate scaling indicates that at 1080p Low, the CPU is the bottleneck, limiting the GPU’s output; as resolution increases to 1440p, the GPU gradually becomes the limiting factor, allowing the CPU to feed more frames.

The transition from 1440p to 4K shows more uniform scaling: at High settings, the drop is from 161.5 to 84 FPS (a 48.0% reduction), and at Low settings, the drop is from 329.8 to 175.2 FPS (a 46.9% reduction). This consistency suggests that at 4K, the RTX 4090 is firmly the performance limiter, with the CPU providing ample headroom. The Ultra preset at 4K (82.8 FPS) versus 1440p Ultra (158.4 FPS) shows a 47.7% reduction, further confirming GPU-bound behavior.

The data shows that at 1080p, the CPU’s 12 cores and 20 threads are sufficient to push frame rates beyond 400 FPS at Low, but the game’s engine does not scale perfectly with additional threads, as evidenced by the 3DMark single-thread score of 1,043 versus the max-thread score of 9,979. At 4K, the GPU’s memory bandwidth of 1.01 TB/s and 24 GB of GDDR6X memory become the critical factors, and the measured FPS drop from 1080p to 4K—averaging approximately 70% across presets—indicates that the RTX 4090 is operating near its rendering limits in this simulation title. The 4K Low result of 175.2 FPS versus 1080p Low of 401.4 FPS shows a 56.3% drop, which is larger than the theoretical pixel count increase, suggesting that the game’s simulation logic also scales with resolution in ways that affect CPU load.
