Pc Building Simulator

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor based on the Zen 2 (Matisse) architecture, built on a 7 nm process at TSMC. It operates with a base clock of 3.60 GHz and a boost clock of 4.20 GHz, with a 65 W TDP. The chip has a 32 MB shared L3 cache, 512 KB of L2 per core, and 64 KB of L1 per core. Memory support is dual-channel DDR4 with a bandwidth of 51.2 GB/s, and the CPU connects via PCIe Gen 4 with 16 lanes.

In the context of Pc Building Simulator, the game's workload is not heavily threaded in the traditional sense of rendering a 3D scene frame-by-frame; rather, the simulation involves managing system components, running diagnostic tools, and calculating performance metrics. The Ryzen 5 3600’s 12 threads provide ample parallelism for these background computations. Benchmark data shows the CPU scores 4605 in 3DMark with 16 threads, 3844 with 8 threads, and 2579 with 4 threads, indicating scaling that flattens beyond 8 threads. The single-thread score of 696 in 3DMark and 2124 in Cinebench R23 single-core suggest that the per-core performance is modest by modern standards, but sufficient for this simulation genre.

The processor's average benchmark score is 18129, placing it in the 76th percentile among all CPUs. Its nearest rival, the Intel Core i5-11400, scores 18150, a delta of -0.1%, meaning the Ryzen 5 3600 is essentially on par. The AMD Ryzen 5 7535HS is 0.2% ahead at 18101, while the Ryzen 5 1600 is 0.2% behind at 18158 (note the delta sign convention: a negative deltaPct means the rival is higher). The AMD EPYC 9274F is 0.3% behind at 18189. These near-identical scores indicate that the CPU is not a differentiator in this game’s performance envelope; the bottleneck lies elsewhere.

For Pc Building Simulator, the data shows that at 1080p Low settings, the combo achieves 255.3 FPS, which is far beyond any display refresh rate. The CPU's 12 threads handle the simulation logic, while the GPU renders the shop and workstation environments. The measured FPS deltas from 1080p to 4K (detailed later) confirm that the CPU is not the limiting factor at lower resolutions, but at 4K Ultra (87.7 FPS), the GPU workload dominates. The Ryzen 5 3600's 76th percentile ranking means it outperforms 76% of all CPUs, yet its rivals are within 0.3%, suggesting that any of these chips would yield nearly identical results in this game.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured FPS rows provide a clear hierarchy across settings at each resolution. At 1080p, Low yields 255.3 FPS, Medium 224.8 FPS, High 200.7 FPS, and Ultra 193.4 FPS. The step from Low to Medium costs 30.5 FPS (about 12%), while Medium to High costs 24.1 FPS (about 11%), and High to Ultra costs only 7.3 FPS (about 4%). This diminishing penalty suggests that the Ultra preset is not significantly more demanding than High, making High the sweet spot for visual fidelity with minimal FPS loss.

At 1440p, the pattern shifts: Low gives 223.9 FPS, Medium 197 FPS, High 172.1 FPS, and Ultra 163.2 FPS. The gap between Medium and High is 24.9 FPS (about 13%), and High to Ultra is 8.9 FPS (about 5%). The 4K data shows a more dramatic drop: Low 179.5, Medium 124.4, High 89.4, and Ultra 87.7. Here, the jump from Low to Medium costs 55.1 FPS (31%), and Medium to High costs 35 FPS (28%), while High to Ultra is negligible at 1.7 FPS.

The optimal experience depends on the display. For 1080p users, High at 200.7 FPS is the best balance, as Ultra adds only 7.3 FPS penalty. For 1440p, High at 172.1 FPS remains strong, with Ultra only 8.9 FPS lower. For 4K, High at 89.4 FPS is playable, but Ultra at 87.7 FPS is nearly identical, so there is no reason to avoid Ultra if the display supports it. However, the data suggests that Medium at 4K (124.4 FPS) offers a more fluid experience than High, with 35 FPS more headroom. The measured rows do not include minimum FPS values, so the analysis relies solely on averages.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling from 1080p to 4K reveals a classic GPU-bound pattern. At Low settings, 1080p yields 255.3 FPS, 1440p drops to 223.9 FPS (a 12.3% reduction), and 4K falls to 179.5 FPS (a 29.7% reduction from 1080p). At Medium settings, the decline is steeper: 1080p 224.8, 1440p 197 (12.4% less), and 4K 124.4 (44.7% less). At High settings, 1080p 200.7, 1440p 172.1 (14.3% less), and 4K 89.4 (55.5% less). At Ultra settings, 1080p 193.4, 1440p 163.2 (15.6% less), and 4K 87.7 (54.7% less).

The increasing percentage drop at higher settings indicates that the GeForce RTX 5090's rendering workload scales with pixel count, and the GPU becomes the limiting factor as resolution increases. At 1080p, the CPU has more headroom, allowing the RTX 5090 to push beyond 250 FPS. At 4K, the GPU's fill rate and shading capacity are saturated, and the FPS drops accordingly. The RTX 5090 has a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s, with 176 ROPs and 680 TMUs, which explains its ability to maintain playable FPS even at 4K Ultra.

The data shows that the FPS drop from 1440p to 4K at High settings (172.1 to 89.4, a 48% reduction) is more severe than the drop from 1080p to 1440p (200.7 to 172.1, a 14% reduction). This non-linear scaling is typical of GPU-bound scenarios where 4K quadruples the pixel count relative to 1080p, but the FPS does not quarter because the game's simulation workload remains constant. The CPU's 12 threads handle the non-rendering tasks, and at 1080p Low, the 255.3 FPS suggests the CPU can keep up with the GPU's frame generation up to that point. Beyond that, the GPU is the constraint.

FAQ

Q: Is the AMD Ryzen 5 3600 a bottleneck for the RTX 5090 in Pc Building Simulator?

A: The data shows that at 1080p Low, the combo reaches 255.3 FPS, which is high but not saturating the RTX 5090's potential. The CPU's average benchmark score is 18129, within 0.3% of its nearest rivals, indicating it is not a limiting factor. The FPS drops from 1080p to 4K are consistent with GPU-bound scaling, suggesting the CPU is sufficient.

Q: What is the best setting for a 1440p 144 Hz monitor?

A: At 1440p, the High preset delivers 172.1 FPS, which exceeds 144 Hz. The Ultra preset gives 163.2 FPS, still above 144 Hz. Either setting works, but High offers a 8.9 FPS advantage over Ultra with minimal visual loss.

Q: How does the RTX 5090 compare to its nearest rival in benchmarks?

A: The RTX 5090 has an average benchmark score of 84306, placing it in the 94th percentile. Its closest rival, the RTX 5090 D, scores 84241 (0.1% higher delta), while the RTX 5050 Mobile is 0.2% higher at 84171. The AMD Radeon PRO W6600 is 1.3% higher at 83209, and the NVIDIA CMP 40HX is 1.6% lower at 85637.

Q: Does the RTX 5090's 32 GB VRAM matter for this game?

A: The RTX 5090 has 32 GB of GDDR7 memory with a 512-bit bus and 1.79 TB/s bandwidth. Pc Building Simulator is not VRAM-intensive, so the 32 GB capacity is unlikely to be a constraint.

A: The measured data shows 124.4 FPS at 4K Medium, which is 35 FPS higher than High (89.4 FPS) and 36.7 FPS higher than Ultra (87.7 FPS). Medium provides a smoother experience at 4K if frame rate is prioritized.

Q: Is the Ryzen 5 3600's single-thread performance adequate?

A: The CPU scores 696 in 3DMark single-thread and 892 in Cinebench R20 single-core. These are modest scores, but the game's simulation logic appears to benefit from multi-threading (the 12 threads), as evidenced by the high FPS at 1080p Low (255.3 FPS). Single-thread performance is not a bottleneck in the measured data.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5090 is built on the Blackwell 2.0 architecture, using the GB202 chip on a 5 nm process at TSMC. It has 21,760 shading units, 680 TMUs, and 176 ROPs, with 170 RT cores and 680 tensor cores. The GPU operates at a base clock of 2017 MHz and boosts to 2407 MHz, with memory running at 1750 MHz (28 Gbps effective). The 32 GB of GDDR7 memory is connected via a 512-bit bus, providing 1.79 TB/s of bandwidth. The card has a TDP of 575 W and requires a 950 W PSU, with a dual-slot design and a single 16-pin power connector.

In Pc Building Simulator, the GPU's role is primarily to render the 3D workspace, components, and PC cases. The RTX 5090's 104.8 TFLOPS of FP32 performance and 423.6 GPixel/s pixel rate explain why it can push 255.3 FPS at 1080p Low. The card's benchmark scores are impressive: a Passmark G3D score of 39650, a Geekbench OpenCL score of 380114, and a 3DMark Steel Nomad DX12 score of 14411. Its average benchmark score is 84306, placing it in the 94th percentile of all GPUs.

The nearest rival, the RTX 5090 D, has a deltaPct of 0.1% (score 84241), meaning the two are effectively identical. The RTX 5050 Mobile is 0.2% higher at 84171, while the AMD Radeon PRO W6600 is 1.3% higher at 83209, and the NVIDIA CMP 40HX is 1.6% lower at 85637. These tight deltas suggest that the RTX 5090's performance tier is well-established, with no single competitor offering a significant advantage.

For this game, the RTX 5090 is overkill at lower resolutions, as evidenced by the 255.3 FPS at 1080p Low. The GPU becomes the limiting factor at 4K, where the FPS drops to 89.4 at High settings. The 32 GB VRAM is far more than the game requires, but the high bandwidth and compute throughput ensure that even at 4K Ultra, the card delivers 87.7 FPS. The GPU's 94th percentile ranking means it outperforms 94% of all GPUs, but the measured FPS data shows that the game engine itself caps the performance, likely due to simulation logic that runs on the CPU.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the measured average FPS values are: Low 255.3, Medium 224.8, High 200.7, and Ultra 193.4. The spread from Low to Ultra is 61.9 FPS, with the largest single drop being 30.5 FPS from Low to Medium. The difference between High and Ultra is only 7.3 FPS, suggesting that Ultra is a minor increment over High.

At 2560x1440, the values are: Low 223.9, Medium 197, High 172.1, and Ultra 163.2. The spread is 60.7 FPS. The drop from Low to Medium is 26.9 FPS, Medium to High is 24.9 FPS, and High to Ultra is 8.9 FPS. The pattern is consistent with 1080p, where Ultra adds a small penalty over High.

At 3840x2160, the values are: Low 179.5, Medium 124.4, High 89.4, and Ultra 87.7. The spread is 91.8 FPS. The drop from Low to Medium is 55.1 FPS, Medium to High is 35 FPS, and High to Ultra is only 1.7 FPS. This is a significant divergence from lower resolutions: at 4K, High and Ultra are nearly identical, while Medium offers a substantial 35 FPS advantage over High.

Comparing across resolutions, the FPS at 1080p Low (255.3) is 42.3% higher than at 4K Low (179.5). At Medium, 1080p (224.8) is 80.7% higher than 4K (124.4). At High, 1080p (200.7) is 124.5% higher than 4K (89.4). At Ultra, 1080p (193.4) is 120.6% higher than 4K (87.7). These percentages confirm that the GPU's workload scales non-linearly with resolution, and the game benefits from higher resolutions only if the display supports it, with the caveat that 4K High and Ultra are nearly indistinguishable in frame rate.

The combo rank in game is 288 out of 1769 combos, placing it in the top 16.3% of tested configurations. This ranking reflects the RTX 5090's high-end status, but the CPU's 76th percentile and the modest single-thread scores suggest that the combo is not optimized for this specific simulation title. The measured FPS data is marked as "dataIsMeasured: true," meaning the values come from actual testing rather than estimation, lending credibility to the analysis.
