Pc Building Simulator

Pc Building Simulator is a simulation title that responds strongly to both processor and graphics hardware, and the AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 3070 Ti delivers a performance profile that is surprisingly GPU-bound at high resolutions but becomes increasingly CPU-sensitive at lower ones. The measured data shows this combo sitting at rank 669 out of 1769 tested combinations, placing it in the upper-middle tier of all systems tested in this game. The CPU's 82nd percentile standing among all processors and the GPU's 74th percentile among all graphics cards suggest a balanced pairing, though the benchmark results reveal that the RTX 3070 Ti is the primary bottleneck for this game's rendering pipeline at most settings.

CPU Role

The AMD Ryzen 5 8400F brings six cores and twelve threads based on the Zen 4 architecture, running on the 4 nm TSMC process node. Its base clock of 4.20 GHz and boost clock of 4.70 GHz provide strong single-threaded performance that is critical for simulation games, which often rely on game logic and physics calculations that do not scale perfectly across many cores. The processor's 3DMark single-thread score of 951 and Cinebench R23 single-core score of 2943 indicate robust per-core performance, while the multi-threaded results — Cinebench R23 multicore at 20851 and PassMark multithread at 24530 — show it can handle background tasks and complex simulation workloads without becoming a limiting factor.

In Pc Building Simulator specifically, the CPU's role becomes apparent when examining the frame rate scaling across settings. At 1080p with Low settings, the combo achieves 316.3 FPS, which is a massive jump from the 149.6 FPS seen at Ultra settings. This gap of over 166 FPS suggests that at lower graphical presets, the CPU is capable of feeding the GPU far more frames than the graphics card can render under heavier loads. The Ryzen 5 8400F's PassMark single-thread score of 3684 and its 3DMark 2-thread score of 1874 indicate that even lightly threaded workloads are handled efficiently, which matters for a game that simulates component interactions and PC building tasks. The CPU's 65 W TDP and 16 MB shared L3 cache are adequate for this genre, and the benchmark data shows no signs of CPU throttling or bottlenecking at any resolution tested.

Settings Recommendations

The measured FPS data clearly indicates that the Medium preset offers the best balance of visual quality and performance for this combo. At 1080p, Medium delivers 226.8 FPS, which is 77.1 FPS higher than High at 158.7 FPS and 77.2 FPS higher than Ultra at 149.6 FPS, while still providing substantially better visuals than Low at 316.3 FPS. The gap between Medium and High is significant enough that most users would prefer the smoother experience, especially since the visual difference in a simulation game is often less noticeable than in fast-paced shooters.

At 1440p, the Medium preset yields 143.4 FPS, which remains well above the 60 FPS threshold for smooth gameplay and is 41.8 FPS higher than High at 101.6 FPS. Even at 4K, Medium produces 76.1 FPS, which is playable on most displays, while High drops to 52.9 FPS and Ultra to 51.8 FPS. The data suggests that Medium is the sweet spot across all resolutions, providing a 43.8% performance uplift over High at 1080p and a 43.9% uplift at 1440p, with only a modest visual compromise that is unlikely to detract from the simulation experience.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture using an 8 nm Samsung process, featuring 6144 shading units, 192 texture mapping units, and 96 raster operation pipelines. Its 8 GB of GDDR6X memory on a 256-bit bus provides 608.3 GB/s of bandwidth, which is substantial for a 30-series card. The GPU's base clock of 1575 MHz and boost clock of 1770 MHz, combined with its 21.75 TFLOPS FP32 performance, make it capable of handling modern game workloads. The memory clock of 1188 MHz translates to 19 Gbps effective, and the 48 ray tracing cores and 192 tensor cores add versatility for games that support these features.

In Pc Building Simulator, the GPU's role is clearly demonstrated by the frame rate scaling across resolutions. At 1080p, the combo achieves 316.3 FPS on Low, 226.8 FPS on Medium, 158.7 FPS on High, and 149.6 FPS on Ultra. When moving to 1440p, these numbers drop to 203.8, 143.4, 101.6, and 98.6 FPS respectively. At 4K, the figures fall further to 108.1, 76.1, 52.9, and 51.8 FPS. The consistent pattern of roughly 35-40% performance decreases when moving from 1080p to 1440p, and another 45-50% drop from 1440p to 4K, indicates that the RTX 3070 Ti's rendering throughput is the primary constraint as pixel count increases. The GPU's PassMark G3D score of 23356 and its 3DMark Steel Nomad DX12 score of 3478 place it at the 74th percentile, confirming its mid-range-to-upper-mid-range positioning.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce 316.3 FPS, Medium produces 226.8 FPS, High produces 158.7 FPS, and Ultra produces 149.6 FPS. The difference between Low and Ultra is 166.7 FPS, representing a 52.7% reduction in performance when maxing out graphical options.

Moving to 2560x1440, the measured averages are 203.8 FPS on Low, 143.4 FPS on Medium, 101.6 FPS on High, and 98.6 FPS on Ultra. The gap between Low and Ultra here is 105.2 FPS, a 51.6% reduction. Compared to 1080p, each setting experiences a proportional drop: Low falls by 35.6%, Medium by 36.8%, High by 36.0%, and Ultra by 34.1%.

At 3840x2160, the results show 108.1 FPS on Low, 76.1 FPS on Medium, 52.9 FPS on High, and 51.8 FPS on Ultra. The Low-to-Ultra gap narrows to 56.3 FPS, a 52.1% reduction. Relative to 1440p, the 4K results show drops of 47.0% for Low, 46.9% for Medium, 47.9% for High, and 47.5% for Ultra. These consistent percentage drops across all settings strongly indicate that the GPU is the limiting component, as the CPU's performance would not scale this predictably with resolution changes.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals the bottleneck structure of this combo. At Low settings, performance falls from 316.3 FPS at 1080p to 108.1 FPS at 4K, a 65.8% reduction. Medium settings see a drop from 226.8 to 76.1 FPS, a 66.5% reduction. High settings decline from 158.7 to 52.9 FPS, a 66.7% reduction. Ultra settings go from 149.6 to 51.8 FPS, a 65.4% reduction. The uniformity of these percentage drops — all within a narrow 1.3 percentage-point range — is a textbook indicator of GPU-limited performance.

If the CPU were the limiting factor, the frame rate would remain relatively constant across resolutions, as the processor would cap performance regardless of pixel count. Instead, the data shows that each doubling of resolution (from 1080p to 1440p, then 1440p to 4K) results in roughly 35-50% performance penalties, which aligns with the increased pixel count that the RTX 3070 Ti must process. The 8 GB of VRAM and 608.3 GB/s bandwidth are sufficient for this simulation game, as even at 4K Ultra settings the combo maintains 51.8 FPS without indicating memory-related stutters or crashes. The scaling pattern suggests that users with 1080p or 1440p displays are well-served by this combo, while 4K users should stick to Medium settings or lower to maintain playable frame rates above 60 FPS.
