Pc Building Simulator

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 4070 delivers a measured performance profile in Pc Building Simulator that is strong across all tested resolutions. The data shows a combo rank of 402 out of 1769 tested combinations, placing it in the top quarter of the database. This analysis breaks down the measured FPS, settings scaling, and the roles of the CPU and GPU.

Settings Recommendations

The measured FPS rows reveal a clear hierarchy across presets. At 1920x1080, every setting exceeds 175 FPS, with Low at 367.4, Medium at 260.2, High at 180.3, and Ultra at 175.1. Since even Ultra stays well above 144 Hz, the highest quality preset is the obvious choice for 1080p displays. At 2560x1440, the spread narrows: Low hits 233.8, Medium 163.7, High 118.7, and Ultra 110.9. Here, High and Ultra are both comfortably above 100 FPS, but High offers a 7.8 FPS advantage over Ultra (118.7 vs 110.9) with only a minor visual trade-off, making High the more balanced pick for 1440p. At 3840x2160, the situation changes: Ultra averages 59.6 FPS, just below the 60 FPS threshold, while High reaches 62.4 and Medium jumps to 83.5. For a smooth 4K experience, Medium is the recommended preset, as it provides a 20.9 FPS improvement over High (83.5 vs 62.4) while still delivering a substantial quality boost over Low (120.1). The data suggests that the GPU becomes the limiting factor at 4K, and Medium is the sweet spot for maintaining fluidity without sacrificing too much visual fidelity.

GPU Role

The RTX 4070 brings 12 GB of GDDR6X memory on a 192-bit bus, with a bandwidth of 504.2 GB/s. Its base clock is 1920 MHz and boost clock is 2475 MHz. These specifications are directly relevant to Pc Building Simulator, a simulation that likely loads many assets and textures. The measured FPS scaling across resolutions indicates that the GPU is the primary driver of performance at higher settings. At 4K, the difference between Low and Ultra is 60.5 FPS (120.1 vs 59.6), while at 1080p the same gap is 192.3 FPS (367.4 vs 175.1). This disproportionate drop at 4K points to the GPU's memory bandwidth and compute capacity being saturated. The GPU's average benchmark score is 37283, placing it at the 81st percentile of all GPUs. Its nearest rivals include the AMD Radeon RX Vega 56 (delta -0.6%) and the NVIDIA GeForce RTX 4080 Mobile (delta -2.2%), showing that the RTX 4070 sits in a competitive mid-to-high tier. The 12 GB VRAM is ample for this game, as no VRAM-related bottlenecks are evident in the FPS data. The GPU's launch MSRP is 599 USD.

How This Combo Ranks

The combination of the Ryzen 5 8400F and RTX 4070 achieves a rank of 402 out of 1769 tested combos in Pc Building Simulator. This places it in the top 22.7% of all pairings in the database. The CPU itself holds an 82nd percentile ranking among all CPUs, while the GPU sits at the 81st percentile, indicating a well-matched pair. The CPU's average benchmark score is 25064, with nearest rivals including the AMD Ryzen 7 2700X (delta 0%), the AMD Ryzen AI 5 PRO 340 (delta -0.1%), and the AMD Ryzen 5 7500F (delta 0.3%). The GPU's average score is 37283, with the closest competitor being the AMD Radeon RX Vega 56 (delta -0.6%). These percentile and delta values suggest that both components are near the top of their respective performance tiers, and the combo rank reflects that synergy. The data shows that this pairing is not an outlier but a consistent performer, likely due to the balanced capabilities of the 6-core CPU and the 12 GB GPU.

Measured FPS Breakdown

The following table lists all measured average FPS values from the FACT PACK:

| Resolution | Settings | Avg FPS |

|------------|----------|---------|

| 3840x2160 | High | 62.4 |

| 3840x2160 | Low | 120.1 |

| 3840x2160 | Medium | 83.5 |

| 3840x2160 | Ultra | 59.6 |

| 2560x1440 | High | 118.7 |

| 2560x1440 | Low | 233.8 |

| 2560x1440 | Medium | 163.7 |

| 2560x1440 | Ultra | 110.9 |

| 1920x1080 | High | 180.3 |

| 1920x1080 | Low | 367.4 |

| 1920x1080 | Medium | 260.2 |

| 1920x1080 | Ultra | 175.1 |

At 1080p, the jump from Low to Medium is 107.2 FPS (367.4 to 260.2), while the jump from High to Ultra is only 5.2 FPS (180.3 to 175.1). This suggests diminishing returns at the top end. At 1440p, the pattern is similar: Low to Medium gains 70.1 FPS, but High to Ultra loses 7.8 FPS. At 4K, the differences are more compressed: Low to Medium gains 36.6 FPS, Medium to High loses 21.1 FPS, and High to Ultra loses 2.8 FPS. The data indicates that the GPU's performance headroom shrinks as resolution increases, making the choice of preset more critical at 4K.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and non-linear. At High settings, the average FPS goes from 180.3 at 1080p to 118.7 at 1440p (a 34.2% reduction) and then to 62.4 at 4K (a 47.4% reduction from 1440p). At Low settings, the drop is 367.4 to 233.8 (36.4%) and then to 120.1 (48.6%). This pattern holds across all presets, with the 4K step consistently halving the 1440p performance. The scaling suggests that the GPU is the limiting component at higher resolutions, as the pixel count increases by 2.25x from 1440p to 4K, but the FPS drops by roughly half. In contrast, the CPU's role is more prominent at 1080p, where the GPU is less stressed and the frame rates are extremely high. The data implies that for 4K gaming, the RTX 4070 is the bottleneck, while at 1080p the CPU is more than capable of feeding the GPU.

CPU Role

The Ryzen 5 8400F is a 6-core, 12-thread processor with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. It has 16 MB of shared L3 cache and a TDP of 65 W. Its Cinebench R23 multi-core score is 20851 and single-core is 2943, with a 3DMark max-threads score of 6165. The CPU's percentile is 82, and its nearest rivals include the AMD Ryzen 7 2700X (delta 0%) and the AMD Ryzen 5 7500F (delta 0.3%). In Pc Building Simulator, the CPU's impact is most visible at 1080p, where the GPU is not the limiting factor. At 1080p Low, the combo achieves 367.4 FPS, which is far beyond typical display refresh rates, indicating that the CPU is not a bottleneck. Even at 1080p Ultra, the 175.1 FPS is well above 144 Hz. The CPU's boost clock of 4.70 GHz and 6 cores are sufficient for the simulation's logic and physics, as the FPS data shows no CPU-related stutters or drops. The CPU's launch MSRP is $170.
