# Pc Building Simulator with AMD Ryzen 5 8400F + NVIDIA GeForce RTX 3080 Ti

This combination of AMD's 6-core Zen 4 processor and NVIDIA's Ampere flagship-tier GPU produces remarkably high frame rates in Pc Building Simulator, a simulation title that rarely stresses modern hardware. The measured data reveals a system that delivers playable performance even at 4K Ultra, while at 1080p Low it exceeds 360 FPS, suggesting the game itself becomes the limiting factor long before either component reaches its ceiling.

GPU Role

The NVIDIA GeForce RTX 3080 Ti brings substantial graphics horsepower to Pc Building Simulator, with 12 GB of GDDR6X memory on a 384-bit bus delivering 912.4 GB/s of bandwidth. The GA102 chip contains 10,240 shading units, 320 texture mapping units, and 112 raster output pipelines, with base and boost clocks of 1365 MHz and 1665 MHz respectively. This configuration yields 34.10 TFLOPS of FP32 compute and a pixel rate of 186.5 GPixel/s.

The GPU's memory subsystem appears well-matched to the demands of this simulation. At 4K Ultra, the system averages 57 FPS, which suggests the 12 GB frame buffer is sufficient for the game's highest settings at this resolution. The bandwidth of 912.4 GB/s likely prevents memory bottlenecks even when the scene complexity increases with detailed PC component models. The RTX 3080 Ti's 80 RT cores and 320 tensor cores are present but likely underutilized in this title, as Pc Building Simulator focuses on assembly and management rather than ray-traced rendering.

The GPU's performance scaling across settings reveals its capabilities. At 4K, moving from Low to Medium costs 36 FPS (121 to 85), while Medium to High costs another 25 FPS (85 to 60). The jump from High to Ultra costs only 3 FPS (60 to 57), indicating that Ultra's additional visual features are comparatively cheap at this resolution. This pattern suggests the GPU handles the game's rendering efficiently, with diminishing returns on higher settings.

How This Combo Ranks

With a rank of 886 out of 3,723 tested combinations, this pairing sits comfortably in the upper quarter of all configurations for Pc Building Simulator. The 77th percentile CPU and 83rd percentile GPU combine to produce frame rates that exceed the requirements of most displays, even at higher resolutions.

The ranking reflects a balanced pairing rather than an extreme one. The Ryzen 5 8400F's 6 cores and 12 threads provide adequate processing power for the simulation's logic, while the RTX 3080 Ti handles the visual rendering. Neither component dramatically outperforms the other, which is reflected in the combo's solid but not top-tier ranking. Configurations with higher percentile GPUs or CPUs would likely rank higher, but the data shows this pairing avoids significant bottlenecks.

The gap between this combo and the top of the rankings likely stems from the CPU's position. While the 8400F performs well in synthetic benchmarks, its 16 MB of shared L3 cache and DDR5 memory support provide a solid foundation, but higher-core-count processors with more cache would offer additional headroom in simulation-heavy scenarios. However, the measured FPS data indicates the game rarely demands that extra capability.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all settings. Low settings produce 366 FPS average, while Medium yields 259 FPS with a minimum of 220 and maximum of 298. High settings achieve 183 FPS, and Ultra maintains 174 FPS. The difference between High and Ultra is just 9 FPS, suggesting the Ultra preset adds minimal visual improvements relative to its cost.

Moving to 2560x1440, the system remains highly capable. Low settings produce 231 FPS, Medium delivers 163 FPS (min 139, max 188), High achieves 115 FPS, and Ultra maintains 110 FPS. The scaling from 1080p to 1440p costs roughly 37-40% of the frame rate across settings, which is consistent with the increased pixel count.

At 3840x2160, performance becomes more constrained but remains playable. Low settings yield 121 FPS, Medium produces 85 FPS (min 73, max 98), High achieves 60 FPS, and Ultra drops to 57 FPS. The 4K results show a clear GPU limitation, particularly at higher settings where the frame rate approaches the 60 FPS threshold.

The measured data includes minimum and maximum values only for Medium settings at each resolution, showing 220-298 FPS at 1080p, 139-188 FPS at 1440p, and 73-98 FPS at 4K. These ranges indicate consistent performance without significant frame time spikes.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals where the bottleneck shifts. At 1080p Low, the system produces 366 FPS, which drops to 231 FPS at 1440p (a 37% reduction) and 121 FPS at 4K (a 67% reduction from 1080p). This scaling closely follows the pixel count increase, with 4K requiring 4x the pixels of 1080p.

At Ultra settings, the scaling is more moderate: 174 FPS at 1080p drops to 110 FPS at 1440p (37% reduction) and 57 FPS at 4K (67% reduction). The consistency of these percentage drops across settings suggests the GPU is the primary limiting factor at higher resolutions, while the CPU can maintain adequate frame delivery.

The fact that 1080p Low reaches 366 FPS indicates the CPU is not heavily stressed by this game. If the processor were the bottleneck, we would expect diminishing returns at lower resolutions where GPU load decreases. Instead, the system continues to scale with resolution, implying the RTX 3080 Ti is the constraining component at 4K while the Ryzen 5 8400F has sufficient headroom even at high frame rates.

Settings Recommendations

For 4K displays, Medium settings at 85 FPS provide the best balance of visual quality and smoothness. High settings at 60 FPS are exactly at the refresh rate boundary for standard displays, while Ultra at 57 FPS may cause noticeable judder on 60 Hz panels. The 12 FPS difference between Medium and High is modest, but the 25 FPS difference between Low and Medium suggests Medium captures most of the visual improvements without sacrificing performance.

At 1440p, High settings at 115 FPS are ideal for 120 Hz displays, while Ultra at 110 FPS offers nearly identical performance with slightly better visuals. The 5 FPS difference between these settings makes Ultra a reasonable choice for users with high-refresh-rate monitors. Medium at 163 FPS would suit 165 Hz panels, though the visual trade-off may not be worth the extra frames.

For 1080p, the system has enough performance to run Ultra at 174 FPS, which exceeds most displays' refresh rates. Even the most demanding settings produce frame rates well above 144 Hz, making this resolution the clear sweet spot for maximum visual fidelity. The 366 FPS at Low settings is only relevant for competitive play or extreme refresh rate displays, as the visual sacrifice is substantial.

CPU Role

The AMD Ryzen 5 8400F provides 6 cores and 12 threads based on the Zen 4 architecture, with a base clock of 4.20 GHz and boost clock of 4.70 GHz. Built on TSMC's 4 nm process, the Phoenix chip contains 25,000 million transistors on a 178 mm² die. The 65 W TDP indicates efficient power delivery, while the 16 MB shared L3 cache and 83.2 GB/s dual-channel DDR5 memory bandwidth support the CPU's performance.

Benchmark results show the 8400F excels in multithreaded workloads, scoring 20,851 in Cinebench R23 multicore and 8,757 in R20 multicore. Single-thread performance is also strong at 2,943 in R23 single-core and 951 in 3DMark single-thread. These scores place the CPU in the 77th percentile, with its 25,005 average benchmark score nearly identical to the Ryzen 5 7500F's 24,964.

In Pc Building Simulator, the CPU's role is primarily managing game logic, component interactions, and physics calculations. The 12 threads provide ample parallelism for these tasks, while the high boost clock ensures responsive single-threaded performance. The measured frame rates at 1080p Low (366 FPS) demonstrate that the CPU does not bottleneck the GPU even when graphics load is minimal. The 8400F's performance relative to rivals—0.2% above the 7500F and 0.3% above the i7-11850H—suggests it delivers competitive simulation performance without requiring excessive power or cooling.
