Pc Building Simulator

Pc Building Simulator presents an interesting case study for this Intel Core i5-9400 and NVIDIA GeForce RTX 5070 Ti pairing. The data shows a combination where a modern, high-end GPU meets a previous-generation six-core processor, and the benchmark results reveal a complex interplay between resolution, settings, and component limits. The measured frame rates across the board are high, but the scaling patterns indicate that neither component is a straightforward bottleneck, making this a curious dataset to analyze for simulation enthusiasts.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial, but not uniform across all settings. At 1920x1080 with Ultra settings, the average FPS is 186.2, which drops to 134.4 at 2560x1440, and further down to 69.4 at 3840x2160. This represents a 63% reduction in frame rate from 1080p to 4K at Ultra settings, indicating that the GPU is being pushed increasingly harder as pixel count rises. The pattern is similar for High settings, where the 1080p result of 186.5 FPS falls to 142.7 at 1440p and then to 75.4 at 4K.

Interestingly, the scaling is even more dramatic at Low settings. The 241.3 FPS at 1080p Low drops to 209.4 at 1440p, but then plummets to 149.8 at 4K. This suggests that at lower graphical loads, the CPU becomes more relevant at lower resolutions, but the GPU still dominates the 4K workload. The data implies that at 1080p and 1440p, the i5-9400 is likely nearing its limits, especially at Low settings, while the RTX 5070 Ti has more headroom to stretch its legs. At 4K, the GPU is clearly the limiting factor across all settings, as the pixel throughput demands far exceed what the CPU needs to feed.

GPU Role

The RTX 5070 Ti is a formidable graphics card, and its specifications support the high frame rates observed. With 16 GB of GDDR7 memory on a 256-bit bus, it offers 896.0 GB/s of bandwidth, which is more than sufficient for a game like Pc Building Simulator that doesn't typically have massive texture demands. The card's boost clock of 2452 MHz and its 8960 shading units provide immense raw compute power, reflected in its 43.94 TFLOPS FP32 performance. This GPU sits in the 87th percentile of all GPUs, and its average benchmark score of 52086 places it nearly identical to the NVIDIA GeForce RTX 4080, which scores 52085 with a 0% delta.

The data shows the GPU's strength in this title. At 4K Ultra, the card still manages 69.4 FPS, which is playable, but the transition from Medium to Ultra at 4K (107.1 to 69.4 FPS) reveals a steep performance cost for the highest settings. The GPU's role becomes less dominant at lower resolutions; at 1080p Low, the 241.3 FPS result suggests the card is being held back by other factors, likely the CPU. The RTX 5070 Ti's 16 GB memory capacity is a clear advantage, ensuring that even at 4K with high-resolution textures, there is no VRAM pressure, allowing the card to focus purely on rendering.

CPU Role

The Intel Core i5-9400 is a six-core, six-thread processor from the Coffee Lake generation, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. Its 9 MB of shared L3 cache and dual-channel DDR4 memory support at 42.7 GB/s are modest by today's standards. In CPU benchmarks, it scores 7969 in Cinebench R23 multi-core and 1125 in single-core, placing it in the 50th percentile of all CPUs. Its average benchmark score of 2305 is remarkably close to its nearest rivals, including the Intel Core i3-10305 (2300, 0.2% delta) and the Intel Core i3-1125G4 (2299, 0.2% delta).

For a simulation game, CPU performance is often critical, and the data suggests this processor is a potential bottleneck at lower resolutions. At 1080p Low, the FPS of 241.3 might seem high, but it is only 13% higher than the 209.4 FPS at 1440p Low, whereas the jump from 1440p to 4K Low is a 28% drop. This non-linear scaling implies that at 1080p, the CPU is struggling to keep up with the GPU's ability to produce frames. The six threads are a limiting factor; modern games often benefit from more threads, and the i5-9400's lack of hyper-threading likely caps performance in CPU-intensive scenes. However, at 4K, the CPU's role diminishes, and the GPU becomes the clear constraint, as evidenced by the more uniform scaling across settings.

How This Combo Ranks

This specific combination of the i5-9400 and RTX 5070 Ti ranks 478th out of 1769 tested combos for Pc Building Simulator, placing it in the top 27% of all configurations. This is a respectable ranking, but it highlights that while the GPU is top-tier, the older CPU drags the overall combo down slightly. The data indicates that the GPU's high percentile (87th) is not fully realized due to the CPU's lower standing (50th percentile). This ranking suggests that users with this combo are getting strong performance, but they are leaving some performance on the table compared to pairings with more modern processors. The rank of 478 out of 1769 implies that many other combinations, likely with newer CPUs, achieve higher average frame rates, even if the GPU is less powerful, due to better CPU-GPU balance.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend heavily on the target resolution and desired frame rate. For 4K gaming, the data shows that Ultra settings (69.4 FPS) are playable but may not be ideal for fast-paced action; dropping to High (75.4 FPS) offers a marginal improvement, while Medium (107.1 FPS) provides a significant boost to smoothness, nearly doubling the frame rate of Ultra. For 1440p, Ultra settings (134.4 FPS) are excellent for high-refresh-rate monitors, and even High (142.7 FPS) is well above the 60 FPS threshold. At 1080p, all settings are playable, with Low (241.3 FPS) and Medium (213.3 FPS) being ideal for 240Hz displays, while Ultra (186.2 FPS) still provides an exceptionally smooth experience.

The data suggests that for most users, High settings at 1440p or 4K offer the best balance of visual fidelity and performance. At 1080p, Medium settings are recommended to avoid potential CPU bottlenecks seen at Low settings, as the 241.3 FPS result is likely not consistently achievable due to CPU limits. For 4K, Medium settings appear to be the sweet spot, providing 107.1 FPS, which is more than sufficient for a smooth experience without sacrificing too much visual quality.
