Pc Building Simulator

Pc Building Simulator is a simulation title where frame pacing and component interaction are the primary gameplay mechanics, and the measured results for the Intel Core i5-9400 paired with the NVIDIA GeForce RTX 3070 show a combination that is heavily skewed toward GPU throughput. The data indicates a system that can deliver high refresh rates at mainstream resolutions but begins to buckle under the load of 4K Ultra settings, where the average frame rate drops below the 60 FPS threshold. This pairing ranks in the 830th position out of 1769 tested combos, placing it in the upper-middle tier of configurations, a position that reflects the balance between a six-core CPU and a high-end Ampere GPU.

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

The Intel Core i5-9400 is a Coffee Lake Refresh part with 6 physical cores and 6 threads, a configuration that lacks simultaneous multithreading. Its base clock is 2.90 GHz, which can boost up to 4.10 GHz under load, and it operates within a 65 W TDP envelope. For a simulation game like Pc Building Simulator, which is not typically characterized by heavy multi-threaded physics or AI workloads, the 6-core/6-thread setup provides a baseline level of processing power that is sufficient to avoid becoming the primary bottleneck in most scenarios. The CPU’s L3 cache is 9 MB shared, and it supports dual-channel DDR4 memory with a bandwidth of 42.7 GB/s, which is adequate for feeding the GPU data streams.

In synthetic benchmarks, the i5-9400 scores 803 points in Cinebench R15 multi-core and 113 points in single-core, while in Cinebench R23 it achieves 7969 multi-core and 1125 single-core. These scores place the CPU at the 50th percentile when compared to all CPUs, indicating it is a mid-pack performer. The nearest rivals in the database include the Intel Core i3-10305, which has an average score 0.2% higher, and the Intel Core i7-8809G, which is 0.6% higher, showing that the i5-9400 sits in a tightly contested performance band where minor clock differences dictate ranking. When considering the game’s results, the CPU’s role is to maintain a stable frame delivery pipeline; the data shows that at 1080p with Low settings, the system achieves 241.6 FPS, suggesting that the CPU is capable of driving very high frame rates when the GPU is not saturated.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-9400 and the NVIDIA GeForce RTX 3070 achieves a rank of 830 out of 1769 tested combos in Pc Building Simulator. This places the pairing in the 47th percentile of all configurations, meaning roughly 53% of tested combos deliver higher average FPS in this specific title. The ranking is a direct result of the balance between the CPU’s mid-range compute capability and the GPU’s high-end rasterization power. The RTX 3070 is a significantly stronger component than the CPU, and the data suggests that the i5-9400 may be limiting the GPU’s potential in lower resolution scenarios, but the overall combo still outperforms the majority of systems due to the GPU’s dominance.

Comparatively, the GPU’s nearest rivals include the AMD Radeon RX 6600 XT, which has an average benchmark score 0.9% lower, and the NVIDIA GeForce GTX 980 Ti, which is 1% higher. This indicates that the RTX 3070 is positioned among a group of GPUs that produce similar average scores, yet the actual in-game FPS results for this combo vary widely depending on settings. The combo’s rank is not a reflection of either component’s individual merit, but rather how they interact within the specific constraints of Pc Building Simulator’s rendering engine, which appears to reward raw GPU fill rate more than CPU scheduling.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling pattern as resolution increases, which is indicative of a GPU-bound system at higher pixel counts. At 1080p with Low settings, the combo produces 241.6 FPS, which drops to 191.4 FPS at 1440p and further to 97.6 FPS at 4K. This represents a 59.6% reduction in frame rate from 1080p to 4K, a substantial drop that signals the GPU is the primary limiting factor at higher resolutions. Conversely, when moving from 1080p to 1440p at Low settings, the frame rate drops by 20.8%, which is a moderate decline that still allows for high refresh rates.

At Ultra settings, the scaling is even more pronounced. The system achieves 143.1 FPS at 1080p, 93.7 FPS at 1440p, and 50.9 FPS at 4K. The drop from 1080p to 4K at Ultra is 64.4%, which is a larger percentage loss than at Low settings. This discrepancy suggests that as the render load increases, the GPU’s memory bandwidth and compute resources become the constraining factor, while the CPU’s 6 threads are sufficient to keep up with the frame requests. The data indicates that at 1080p, the CPU is still able to feed the GPU effectively, but at 4K, the GPU is fully saturated, and the CPU has idle headroom, confirming that the RTX 3070 is the dominant component in this configuration.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

Across all tested resolutions, the average FPS values provide a comprehensive view of performance scaling. At 1920x1080, the lowest setting yields 241.6 FPS, Medium produces 214 FPS, High drops to 149.2 FPS, and Ultra is 143.1 FPS. The difference between Low and Ultra at 1080p is 98.5 FPS, showing that the game’s settings have a significant impact on frame rate even at a resolution where the GPU is not fully stressed. Moving to 2560x1440, the Low setting achieves 191.4 FPS, Medium 135.2 FPS, High 93 FPS, and Ultra 93.7 FPS. Notably, High and Ultra at 1440p produce nearly identical results, with only a 0.7 FPS difference, indicating that the Ultra preset’s additional effects do not significantly tax the GPU at this resolution.

At 3840x2160, the performance drops are more severe. Low settings yield 97.6 FPS, Medium 70.2 FPS, High 47.3 FPS, and Ultra 50.9 FPS. The data shows an anomaly where High (47.3 FPS) is lower than Ultra (50.9 FPS), which is likely due to specific rendering paths in the game that are not strictly hierarchical. The 4K results all fall below the 60 FPS threshold except for Low settings, making 4K gaming feasible only at the lowest quality presets. The frame rate deltas between settings widen as resolution increases, with the gap between Low and Ultra expanding from 98.5 FPS at 1080p to 46.7 FPS at 4K, illustrating that the GPU’s limitations become more apparent at higher pixel densities.

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

The NVIDIA GeForce RTX 3070 is built on the Ampere architecture with a GA104 chip manufactured on an 8 nm process by Samsung. It features 5888 shading units, 184 texture mapping units, and 96 raster output units, along with 46 ray tracing cores and 184 tensor cores. The GPU operates at a base clock of 1500 MHz and a boost clock of 1725 MHz, with memory clocked at 1750 MHz (14 Gbps effective). It is equipped with 8 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 448.0 GB/s. The GPU’s pixel rate is 165.6 GPixel/s, and its texture rate is 317.4 GTexel/s, with an FP32 compute throughput of 20.31 TFLOPS.

These specifications directly influence the measured FPS results. The 8 GB VRAM is adequate for Pc Building Simulator’s textures, even at 4K Ultra, which is confirmed by the fact that the game runs without stuttering at 50.9 FPS in that configuration. The GPU’s high memory bandwidth of 448.0 GB/s is critical for the 4K resolution scaling, where the data shows a 59.6% FPS drop from 1080p to 4K at Low settings, indicating that memory bandwidth is a limiting factor. The RTX 3070’s performance percentile is 72, and its average benchmark score is 28238, with nearest rivals including the AMD FirePro S7150 (0.6% higher) and the AMD Radeon RX 6600 XT (0.9% lower). The GPU’s power draw is 220 W, and it requires a 550 W power supply, which is a relevant consideration for system builders but does not affect the benchmark results. The GPU’s role in this combo is to provide the bulk of the rendering performance, and the data shows that it is capable of delivering high frame rates at 1080p and 1440p, but it is pushed to its limits at 4K Ultra, where the average FPS falls below the playable threshold for smooth motion.
