Pc Building Simulator

Settings Recommendations

The measured frame rates across presets reveal a clear hierarchy in Pc Building Simulator. At 1920x1080, the Ultra preset delivers an average of 249.8 FPS, while the High preset achieves 255.4 FPS — a marginal 5.6 FPS difference that falls within typical run-to-run variance. The Medium preset reaches 289.3 FPS, and Low tops out at 326.7 FPS. Given that the gap between High and Ultra is negligible, the High preset offers the best balance for visual fidelity without sacrificing measurable performance.

At 2560x1440, the pattern shifts slightly. Ultra drops to 162.4 FPS, High holds at 172.2 FPS, Medium reaches 240.1 FPS, and Low hits 279.9 FPS. The delta between High and Ultra widens to roughly 10 FPS at this resolution, making High the more sensible choice for sustained high-refresh-rate output. The data indicates that Medium provides a substantial 67.9 FPS advantage over High at 1440p, which could justify stepping down a preset for users targeting 240 Hz displays.

At 3840x2160, the story changes dramatically. Ultra averages 85.7 FPS, High sits at 87 FPS, Medium climbs to 126.4 FPS, and Low reaches 175.6 FPS. The difference between High and Ultra at 4K is a mere 1.3 FPS, effectively making them identical in practice. Medium offers a 39.4 FPS improvement over High, which represents the largest relative jump between adjacent presets at any resolution. For 4K gaming, Medium appears to be the optimal preset — it nearly doubles the Ultra frame rate while presumably retaining reasonable visual quality for a simulation title.

CPU Role

The AMD Ryzen 5 5600 brings six cores and twelve threads to this pairing, based on the Zen 3 architecture codenamed Vermeer. Its base clock of 3.50 GHz and boost clock of 4.40 GHz, combined with a 65 W TDP, place it as a mainstream desktop processor. The L3 cache totals 32 MB shared across all cores, with 64 KB of L1 and 512 KB of L2 per core. Memory bandwidth is rated at 51.2 GB/s over a dual-channel DDR4 interface.

In Pc Building Simulator, the CPU's role becomes increasingly prominent as resolution decreases. At 1080p, the frame rates scale from 249.8 FPS on Ultra to 326.7 FPS on Low, suggesting that the processor is keeping pace with the GPU's output. The single-thread score of 882 in 3dmark and 2584 in Cinebench R23 indicate solid per-core performance, which matters for a simulation game that likely has a primary game logic thread. The multi-thread results — 5,659 in 3dmark max threads and 18,309 in Cinebench R23 — show that the 12 threads provide ample headroom for background simulation tasks.

The CPU's percentile ranking of 79 against all processors, with an average benchmark score of 21,765, places it slightly above the Intel Xeon D-1746TER (21,635, 0.6% delta) and marginally below the AMD EPYC 9554P (21,899, -0.6% delta). This positioning suggests the 5600 is competitive with enterprise parts in synthetic workloads, though those chips target different use cases. The real-world gaming data shows the CPU does not bottleneck the RTX 5090 at 1080p, where the Low preset achieves 326.7 FPS — a figure that indicates both components are working in concert rather than one limiting the other.

GPU Role

The NVIDIA GeForce RTX 5090 represents the flagship of the GeForce 50-series, built on the Blackwell 2.0 architecture with a 5 nm process. Its 32 GB of GDDR7 memory across a 512-bit bus provides 1.79 TB/s of bandwidth, with memory clocked at 1750 MHz (28 Gbps effective). The GPU's base clock of 2017 MHz boosts to 2407 MHz, driving 21,760 shading units, 680 texture mapping units, and 176 ROPs. The 170 RT cores and 680 tensor cores support the full DirectX 12 Ultimate feature set.

In this game, the GPU's massive memory allocation is arguably overkill — Pc Building Simulator's visual complexity does not require anywhere near 32 GB of VRAM, even at 4K Ultra. However, the raw compute throughput (104.8 TFLOPS FP32) and pixel rate of 423.6 GPixel/s allow the card to push very high frame rates even at demanding settings. The measured data confirms this: at 1080p Low, the combination reaches 326.7 FPS, which is likely approaching the game engine's internal limits rather than the GPU's.

The RTX 5090's percentile ranking of 94 against all GPUs, with an average benchmark score of 84,306, places it just above the RTX 5090 D (84,241, 0.1% delta) and the RTX 5050 Mobile (84,171, 0.2% delta). The nearest rival below is the AMD Radeon PRO W6600 (83,209, 1.3% delta), while the NVIDIA CMP 40HX scores higher (85,637, -1.6% delta). These margins are remarkably tight, indicating that the 5090 sits at the top of the GPU hierarchy with little separating it from its closest competitors in synthetic tests. The game's measured frame rates, however, show that this GPU is far ahead of what the Ryzen 5 5600 can fully utilize at lower resolutions.

How This Combo Ranks

The combination of the AMD Ryzen 5 5600 and NVIDIA GeForce RTX 5090 ranks 77th out of 1,769 tested combinations in Pc Building Simulator. This places the pairing in the top 4.4% of all configurations, which is strong but not exceptional given the GPU's flagship status. The ranking reflects a mismatch: the CPU's mid-range positioning (79th percentile) contrasts sharply with the GPU's elite standing (94th percentile), and the combination's overall rank of 77 suggests the CPU is holding back the GPU in this title.

The data indicates that the RTX 5090 is capable of far higher frame rates than the 5600 can feed it. At 1080p Low, the 326.7 FPS result likely represents a CPU-limited scenario, as the GPU should theoretically produce even higher numbers given its synthetic scores. The gap between the CPU's average benchmark score of 21,765 and the GPU's 84,306 illustrates the disparity in their respective performance classes. In a game like Pc Building Simulator, which is not graphically intensive by modern standards, the CPU becomes the primary constraint at lower resolutions, while the GPU takes over at 4K where the frame rates drop to 85.7–175.6 FPS depending on preset.

Resolution Scaling

The measured frame rates reveal how this combination scales across resolutions. Moving from 1080p to 1440p at High settings, the average FPS drops from 255.4 to 172.2 — a reduction of 83.2 FPS, or roughly 32.6%. From 1440p to 4K at High, the drop is more severe: 172.2 to 87 FPS, a loss of 85.2 FPS (49.5%). The cumulative effect from 1080p to 4K at High is a 168.4 FPS reduction, representing a 65.9% decrease in performance.

At Low settings, the scaling pattern is similar but with higher absolute numbers: 326.7 FPS at 1080p falls to 279.9 FPS at 1440p (14.3% drop), then to 175.6 FPS at 4K (37.3% drop). The 4K Low result still exceeds the 1080p Ultra figure of 249.8 FPS, demonstrating that resolution scaling is not uniform across presets. The Medium preset shows the most linear progression: 289.3 FPS at 1080p, 240.1 FPS at 1440p, and 126.4 FPS at 4K.

This scaling behavior identifies the limiting component at each resolution. At 1080p, the relatively small frame rate differences between Low and Ultra (326.7 vs. 249.8 FPS) suggest the CPU is the primary constraint, as the GPU should deliver more consistent performance across presets if it were the bottleneck. At 4K, the larger spread between Low and Ultra (175.6 vs. 85.7 FPS) indicates the GPU becomes the limiting factor, with the 4K Ultra result of 85.7 FPS representing the most GPU-intensive scenario in the dataset. The 1440p results sit in between, with the GPU beginning to assert its influence but the CPU still contributing to overall performance.
