GPU Role

The NVIDIA GeForce RTX 5090 D is built on the Blackwell 2.0 architecture using a 5 nm process at TSMC, with a die containing 92,200 million transistors across 750 mm². Its base clock is 2017 MHz with a boost clock of 2407 MHz, and memory runs at 1750 MHz with 28 Gbps effective speed. The GPU has 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth — a figure that matters for Pc Building Simulator because the game can load many assets simultaneously when rendering detailed PC components and workshop environments.

With 21760 shading units, 680 TMUs, and 176 ROPs, the GPU provides a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s. The FP32 throughput is 104.8 TFLOPS, which is identical to its FP16 rate. These raw compute figures explain why the card pushes high frame rates even at 4K. The RTX 5090 D also includes 170 RT cores and 680 tensor cores, though Pc Building Simulator is not a ray-tracing-heavy title, so these resources contribute less to the measured results than raw rasterization throughput.

The GPU's benchmark data shows strong synthetic performance: a 3DMark Steel Nomad DX12 score of 14326, Geekbench OpenCL score of 310674, and Vulkan score of 376915. Passmark G3D score is 44065, while GPU compute scores 28396. The card ranks in the 92nd percentile of all GPUs, with an average benchmark score of 77712. Its nearest rival, the AMD Radeon RX 6650M XT, scores 76904 — only 1.1% lower — while the RX 6850M XT scores 78940, 1.6% higher. This indicates the RTX 5090 D sits in a tight performance band at the top end of the GPU hierarchy.

In Pc Building Simulator, the GPU's 32 GB VRAM is more than sufficient for the game's textures and simulation data. The measured FPS data shows that the GPU is rarely the bottleneck at lower resolutions, as frame rates scale dramatically from 4K to 1080p. The card's boost clock of 2407 MHz and 1.79 TB/s bandwidth keep texture streaming and rendering smooth even during complex builds with many visible components.

Settings Recommendations

Examining the measured FPS rows across all resolutions, the Medium preset offers the best balance between visual quality and performance headroom. At 1920x1080, Medium delivers 374 FPS average with a minimum of 318 FPS and maximum of 431 FPS. At 2560x1440, Medium produces 254 FPS average (min 216, max 292), and at 3840x2160, it yields 133 FPS average (min 113, max 153). These numbers show that Medium maintains playable frame rates even at 4K while providing more visual fidelity than Low.

The Low preset delivers the highest frame rates — 426 FPS at 1080p, 358 FPS at 1440p, and 187 FPS at 4K — but sacrifices significant visual detail. For a simulation game where reading component labels and observing small details matters, Low may hinder the experience. The Ultra preset, meanwhile, drops to 270 FPS at 1080p, 171 FPS at 1440p, and 89 FPS at 4K. While 89 FPS at 4K Ultra is still smooth, the gap between Ultra and Medium at 4K is 44 FPS (133 vs 89), making Ultra a less attractive choice for high-refresh-rate displays.

High settings sit between Medium and Ultra: 284 FPS at 1080p, 179 FPS at 1440p, and 94 FPS at 4K. The step from High to Ultra costs 14 FPS at 1080p, 8 FPS at 1440p, and 5 FPS at 4K — relatively small penalties. However, the jump from Medium to High costs 90 FPS at 1080p, 75 FPS at 1440p, and 39 FPS at 4K. Given these measured results, Medium provides the widest performance margin while still offering a complete visual experience. For users with 144Hz monitors at 1440p, Medium's 254 FPS gives plenty of headroom, and even 4K Medium at 133 FPS exceeds common 120Hz refresh rates.

Measured FPS Breakdown

At 1920x1080, the combo produces its highest frame rates across all settings. Low settings yield 426 FPS average, Medium delivers 374 FPS (min 318, max 431), High reaches 284 FPS, and Ultra drops to 270 FPS. The spread from Low to Ultra is 156 FPS, indicating that even at the most demanding preset, the system remains far above typical 144Hz display capabilities.

Moving to 2560x1440, all settings deliver lower but still impressive numbers. Low averages 358 FPS, Medium averages 254 FPS with a range of 216 to 292 FPS, High averages 179 FPS, and Ultra averages 171 FPS. The gap between Low and Ultra narrows to 187 FPS, and the difference between High and Ultra is just 8 FPS, suggesting diminishing returns from High to Ultra at this resolution.

At 3840x2160, the frame rates become more moderate but remain highly playable. Low averages 187 FPS, Medium averages 133 FPS (min 113, max 153), High averages 94 FPS, and Ultra averages 89 FPS. The difference between Medium and High is 39 FPS, while High to Ultra costs only 5 FPS. The minimum FPS recorded at 4K Medium is 113, which stays above 100 FPS even in demanding scenes.

The data reveals that this combo is exceptionally fast at 1080p and 1440p, with even Ultra settings exceeding 170 FPS at 1440p. At 4K, the system remains capable of high refresh rates on Medium, and Low settings push past 180 FPS. The measured FPS values also show that Pc Building Simulator is not excessively demanding, as the RTX 5090 D never drops below 89 FPS average in any tested configuration.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial but varies by settings. At Low, the drop is from 426 FPS at 1080p to 358 FPS at 1440p (a 16% decrease) and then to 187 FPS at 4K (a 48% decrease from 1440p, or 56% from 1080p). At Medium, 1080p yields 374 FPS, 1440p yields 254 FPS (32% lower), and 4K yields 133 FPS (48% lower than 1440p, 64% lower than 1080p). High settings go from 284 FPS at 1080p to 179 FPS at 1440p (37% drop) and 94 FPS at 4K (47% drop from 1440p). Ultra starts at 270 FPS at 1080p, falls to 171 FPS at 1440p (37% drop), and reaches 89 FPS at 4K (48% drop).

The scaling pattern — roughly a 32-37% reduction from 1080p to 1440p and about a 47-48% reduction from 1440p to 4K — indicates that the GPU is becoming more of a limiting factor as resolution increases. The fact that 4K frame rates are roughly half of 1080p frame rates suggests the workload is scaling with pixel count as expected. However, the absolute numbers remain high: even at 4K Ultra, the system produces 89 FPS, which is still above 60 FPS for smooth gameplay.

The relatively modest FPS drop from 1440p to 4K (around 47-48% across settings) suggests that the GPU's 32 GB VRAM and 1.79 TB/s bandwidth are sufficient to handle the larger frame buffer without introducing memory-related stalls. If VRAM were insufficient, the scaling would show disproportionate drops at 4K. The consistent scaling across all settings also implies that the CPU is keeping up with the GPU's demands even at lower resolutions, where CPU overhead can become a bottleneck. At 1080p Low, the 426 FPS figure is near the practical limit for many display interfaces, indicating the CPU and GPU combination is well balanced.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor from the 7000 series, based on the Zen 4 architecture (codenamed Raphael) built on a 5 nm process at TSMC. It has a base clock of 4.70 GHz and a boost clock of 5.60 GHz, with a TDP of 170 W. The CPU features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of shared L3 cache. Memory support includes dual-channel DDR5 with 83.2 GB/s bandwidth. The processor uses the AMD Socket AM5 and supports PCIe Gen 5 with 24 lanes.

In Pc Building Simulator, CPU performance matters because the game simulates PC component interactions, including power calculations, thermal dynamics, and compatibility checks. The Ryzen 9 7900X's high boost clock of 5.60 GHz helps with single-threaded tasks like UI rendering and physics calculations, while its 12 cores and 24 threads handle multi-threaded workloads such as simultaneous component simulations.

The CPU's benchmark results show strong multi-threaded capability: Cinebench R23 multi-core scores 29300, while single-core scores 2016.5. Geekbench multi-core reaches 19267 and single-core 2617. Passmark multithread scores 51406, with single-thread at 4238. The 3DMark tests show scaling from 2137 (2 threads) to 12536 (max threads), demonstrating good thread scaling. The CPU ranks in the 91st percentile of all processors, with an average benchmark score of 53288.

Nearest rival comparisons show the Ryzen 9 7900X is closely matched with several high-end processors. The AMD EPYC 7313P scores 53206 (0.2% lower), the Intel Xeon Phi 7290 scores 53469 (0.3% higher), the Intel Xeon 634 scores 52974 (0.6% lower), and the Intel Core i7-14700F scores 53620 (0.6% higher). These small deltas indicate that the 7900X sits in a competitive performance tier.

In the measured FPS data, the CPU's role becomes evident at lower resolutions where frame rates exceed 400 FPS. At 1080p Low, the 426 FPS average suggests the CPU can feed the GPU fast enough to reach very high frame rates. The fact that 1080p Ultra still produces 270 FPS indicates that even at higher settings, the CPU is not a limiting factor. The 12 cores and 24 threads provide ample headroom for background simulation tasks, and the boost clock of 5.60 GHz ensures responsive single-thread performance for game logic.
