Pc Building Simulator

This analysis examines the performance of the Intel Core i7-12700K paired with the NVIDIA GeForce RTX 4070 in Pc Building Simulator. The data provided is measured, offering a clear picture of how this combination handles the simulation across various resolutions and quality presets. The results show a system capable of high frame rates, with distinct scaling patterns that reveal the balance between the CPU and GPU workloads in this specific title.

CPU Role

The Intel Core i7-12700K is a 12-core, 20-thread processor based on the Alder Lake architecture, built on Intel's 10 nm process. It operates with a base clock of 3.60 GHz and can boost up to 5.00 GHz. In synthetic benchmarks, this CPU posts a substantial 3dmark_max_threads score of 9979 and a 3dmark_single_thread score of 1043. The data indicates this processor is a strong performer, ranking in the 89th percentile against all CPUs in the database, with an average benchmark score of 35684.

For a simulation title like Pc Building Simulator, the processor's role is often significant due to the complex logic and physics calculations involved in managing PC components and system builds. The Core i7-12700K's high multi-threaded throughput, reflected in its Cinebench R23 multicore score of 29241, provides ample headroom for these background tasks. However, the measured frame rates suggest that at lower resolutions, the CPU is a primary driver of performance. At 1080p with Low settings, the combo achieves 365.7 FPS, which is a massive leap from the 120.6 FPS observed at 4K Low. This massive scaling factor points to the CPU being less of a bottleneck at 1080p, allowing the GPU to render frames at a much faster rate. The processor's single-thread performance, evidenced by its Passmark single-thread score of 4013, likely contributes to the game's ability to maintain high frame rates when the graphical load is light.

In comparison to its nearest rivals, the Core i7-12700K is closely matched. It is 0.3% behind the AMD Ryzen 7 PRO 5845, which scores an average of 35802, and 0.7% behind the Intel Core i5-14500HX. Conversely, it is 0.6% ahead of the Intel Core i7-13700T and 0.8% ahead of the Intel Core i7-13800H. These negligible deltas mean that in CPU-bound scenarios, the i7-12700K should offer similar performance to these alternatives, making the GPU the more likely determinant of FPS differences at higher resolutions and settings.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture and features 12 GB of GDDR6X memory on a 192-bit bus, delivering a bandwidth of 504.2 GB/s. It has a base clock of 1920 MHz and a boost clock of 2475 MHz. The GPU's benchmark results show a Passmark G3D score of 26927 and a Geekbench OpenCL score of 168006, placing it in the 81st percentile of all GPUs with an average score of 37283.

The GPU's influence becomes more apparent as resolution and graphical settings increase. At 4K Ultra, the combo produces 59.7 FPS, while at 4K High it manages 59.1 FPS. This near-identical performance at the highest settings suggests a hard limit is being hit, likely by the GPU's rendering capabilities. The RTX 4070's 12 GB VRAM is sufficient for this title, and its raw compute power, rated at 29.15 TFLOPS for FP32, is what drives the frame rates at these demanding settings. When compared to its nearest rivals, the RTX 4070 is 1.9% behind the NVIDIA GeForce MX570 A and 2.2% behind the NVIDIA GeForce RTX 4080 Mobile, but it is 0.6% ahead of the AMD Radeon RX Vega 56 and 2.5% ahead of the AMD Radeon RX 5300M. These comparisons indicate that the RTX 4070 sits in a competitive performance tier, and in this simulation, its capabilities are fully utilized only when the resolution is high enough to shift the bottleneck away from the CPU.

Resolution Scaling

The measured FPS data shows a clear and consistent scaling pattern as resolution changes from 1080p to 4K. The most dramatic drop occurs between 1080p and 1440p. At High settings, the average FPS falls from 182.8 at 1080p to 114.4 at 1440p, a reduction of 68.4 FPS. The drop from 1440p to 4K at High settings is less severe, falling to 59.1 FPS, a further loss of 55.3 FPS.

This scaling curve is a classic indicator of a system transitioning from a CPU-bound state to a GPU-bound state. At 1080p, the CPU is able to feed the GPU with data faster than the GPU can render, leading to exceptionally high frame rates like the 365.7 FPS seen at Low settings. As resolution increases, the GPU's rendering workload grows, and it begins to take longer to produce each frame. The system quickly becomes limited by the GPU's fill rate and shader performance. This is evident in the 4K results, where the FPS numbers across different settings (59.1 High, 84.1 Medium, 120.6 Low) are much closer together than they are at 1080p, where the same settings span from 175.5 to 365.7 FPS. The data shows that the GPU is the limiting component at 4K, while the CPU dominates the performance ceiling at 1080p.

How This Combo Ranks

In the grand scheme of tested configurations, the Intel Core i7-12700K and NVIDIA GeForce RTX 4070 combination ranks 415th out of 1769 total combos in Pc Building Simulator. This places it in the top 23.5% of all tested systems, which is a strong showing for a mid-to-high-end pairing.

The rank suggests that while this combo is not at the very top tier of performance, it delivers a very capable experience in this simulation. The 59.1 FPS average at 4K Ultra is just below the 60 FPS target, but the system is more than capable of providing a smooth experience at 1440p, where it achieves 112.8 FPS at Ultra settings. The rank of 415 indicates that there are many systems with more powerful components, such as higher-end GPUs or newer CPUs, that can push higher frame rates, but this specific pairing offers a balanced performance profile that is well-suited for high refresh rate gaming at 1440p and solid 4K gameplay at slightly reduced settings.

FAQ
