Pc Building Simulator

# Pc Building Simulator — AMD Ryzen 7 5800X + NVIDIA GeForce RTX 4090

This combination of an AMD Ryzen 7 5800X and NVIDIA GeForce RTX 4090 delivers exceptional frame rates in Pc Building Simulator, with the data showing a system that is clearly GPU-bound at higher resolutions but capable of exploiting the CPU's strengths at 1080p. The measured results place this combo in the 68th percentile of all 1,769 tested combinations, indicating that while it is not the absolute fastest pairing for this simulation title, it sits comfortably among the top performers.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic pattern of GPU limitation emerging as pixel count increases. At 1080p with Low settings, the system produces 349.8 FPS, but this drops to 296.2 FPS at 1440p and further to 170.5 FPS at 4K with the same settings. The 4K Low result represents a 51.3% reduction from the 1080p Low figure, which is a substantial hit that points squarely at the graphics card being the primary constraint at higher resolutions.

The scaling becomes more dramatic at Ultra settings. The 1080p Ultra result of 245.4 FPS falls to 158.8 FPS at 1440p (a 35.3% drop), and then to 84.7 FPS at 4K (a 65.5% drop from 1080p). This steep decline at 4K Ultra suggests that the RTX 4090 is being pushed hard by the combination of high resolution and maximum graphical features. The RTX 4090's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth are clearly being taxed, as the data shows the gap between 1440p and 4K widening considerably compared to the 1080p to 1440p step.

Interestingly, the gap between Low and Ultra settings shrinks as resolution increases. At 1080p, the spread between Low (349.8 FPS) and Ultra (245.4 FPS) is 104.4 FPS. At 1440p, that spread narrows to 137.4 FPS (296.2 minus 158.8), and at 4K it narrows further to 85.8 FPS (170.5 minus 84.7). This compression at 4K indicates that the GPU is becoming the bottleneck regardless of settings, whereas at 1080p the CPU has more headroom to push higher frame rates when graphical load is reduced.

How This Combo Ranks

The combo holds rank 68 out of 1,769 tested combinations, placing it in the top 3.8% of all pairings in the database for this game. This is a strong showing, though not a dominant one — the data indicates that several other CPU+GPU pairings achieve higher average frame rates in Pc Building Simulator. The ranking reflects a system that is well-balanced for this title, with the Ryzen 7 5800X's 8 cores and 16 threads providing ample processing power for the simulation's logic.

Looking at the CPU's standalone performance, the Ryzen 7 5800X scores an average benchmark of 27,606, which places it in the 84th percentile of all CPUs. Its nearest rivals in the database are the AMD Ryzen 7 5800 (27,535, a 0.3% difference), the AMD Ryzen 5 8500GE (27,708, -0.4%), the Intel Core i7-13700H (27,716, -0.4%), and the Intel Core i5-12600KF (27,827, -0.8%). These deltas are all within 1% of each other, meaning the CPU is not the differentiator here — the GPU's massive performance headroom is what drives the high combo rank.

For the RTX 4090, the average benchmark score is 66,473, placing it in the 91st percentile of all GPUs. Its nearest rivals include the NVIDIA Tesla T4 (66,733, -0.4%), NVIDIA Tesla P40 (66,127, 0.5%), AMD Radeon Pro Vega 56 (67,097, -0.9%), and NVIDIA Quadro P6000 (67,320, -1.3%). These workstation-oriented cards are close in raw compute, but the RTX 4090's gaming-specific features and 24 GB VRAM give it an edge in this simulation title.

GPU Role

The RTX 4090's specifications directly explain its dominance in this game. With 16,384 shading units, 512 texture mapping units, and 176 raster output units, the Ada Lovelace architecture delivers 82.58 TFLOPS of FP32 compute. The boost clock of 2520 MHz (with a base of 2235 MHz) keeps the card running at high throughput, and the memory subsystem — 24 GB of GDDR6X on a 384-bit bus with 1.01 TB/s bandwidth — ensures that texture-heavy scenes in Pc Building Simulator load without stutter.

The 128 ray tracing cores and 512 tensor cores are present, though this simulation title's workload appears to favor raw rasterization over ray tracing based on the measured frame rates. The pixel rate of 443.5 GPixel/s and texture rate of 1,290.2 GTexel/s are the figures that matter most here, and the data shows they are sufficient to push 4K Ultra past 84 FPS.

The GPU's 450 W TDP and triple-slot cooler design are consistent with its high performance ceiling. The suggested 850 W PSU is a practical recommendation for a card of this caliber. The 16-pin power connector and PCIe 4.0 x16 interface are standard for a 40-series flagship, and the end-of-life production status means this is a mature product with well-established drivers in the database.

Measured FPS Breakdown

At 1080p, the system achieves 349.8 FPS on Low settings, 306.9 FPS on Medium, 261 FPS on High, and 245.4 FPS on Ultra. These numbers are exceptionally high, indicating that the RTX 4090 is rarely the limiting factor at this resolution — the Ryzen 7 5800X's single-thread performance (3,327 in Cinebench R23) keeps up with the GPU's output. The difference between Low and Ultra at 1080p is 104.4 FPS, showing that settings have a notable impact when the GPU is not saturated.

Moving to 1440p, the results are 296.2 FPS on Low, 233.7 FPS on Medium, 163 FPS on High, and 158.8 FPS on Ultra. The step from Medium to High at 1440p is a sharp 70.7 FPS drop, which suggests that High settings introduce a significant graphical feature that taxes the GPU more heavily. The gap between High and Ultra at 1440p is only 4.2 FPS, indicating diminishing returns at the top end of the settings spectrum.

At 4K, the frame rates settle into a more constrained range: 170.5 FPS on Low, 119.7 FPS on Medium, 84.2 FPS on High, and 84.7 FPS on Ultra. The near-identical results for High (84.2 FPS) and Ultra (84.7 FPS) at 4K are notable — the 0.5 FPS difference is within measurement noise, suggesting that the GPU hits a hard performance ceiling around 84-85 FPS when pushed to 4K with high-end settings. Low settings at 4K still manage 170.5 FPS, which is playable on high-refresh displays, but the jump to Medium (119.7 FPS) shows a 50.8 FPS penalty for enabling medium-tier effects.

Settings Recommendations

For 4K displays, the data strongly favors the High preset over Ultra. The 4K High result of 84.2 FPS is virtually identical to the 4K Ultra result of 84.7 FPS, yet High likely reduces visual noise and processing overhead without sacrificing measurable frame rate. There is no benefit to running Ultra at 4K with this combo — the 0.5 FPS difference is negligible, and High settings provide the same experience with less GPU strain.

At 1440p, the Medium preset at 233.7 FPS is the sweet spot for high-refresh monitors, delivering over 200 FPS while maintaining decent visual quality. The High preset at 163 FPS is also viable for 144 Hz displays, but Medium offers a 70.7 FPS advantage over High with a modest visual trade-off. Ultra at 158.8 FPS is only 4.2 FPS slower than High, so if visual fidelity matters more than raw frame rate, Ultra is a reasonable choice at 1440p.

For 1080p users, the Medium preset at 306.9 FPS is the best balance of performance and quality. The Low preset at 349.8 FPS provides minimal visual benefit for the 42.9 FPS gain over Medium, and the High preset at 261 FPS is still excellent for any refresh rate. Ultra at 245.4 FPS is overkill for most displays, but the data shows it is perfectly playable if maximum settings are desired.
