# Pc Building Simulator with AMD Ryzen 9 9900X3D + NVIDIA GeForce RTX 5090

This configuration pairs AMD's 12-core Ryzen 9 9900X3D from the Zen 5 Granite Ridge family with NVIDIA's flagship GeForce RTX 5090, built on the Blackwell 2.0 architecture. The measured frame rates in Pc Building Simulator reveal a system that delivers exceptional performance across all tested settings, though the data shows interesting scaling patterns that suggest the game's engine has specific bottlenecks. The combination ranks 41st out of 3002 tested combos, placing it in the top 1.4% of all configurations tested for this title.

Settings Recommendations

The measured data provides clear guidance on which preset delivers the best experience. At 1080p, the Ultra preset produces 253 FPS average, while High settings yield 266 FPS — a modest 13 FPS difference that favors High. However, the Medium preset delivers 377 FPS average, which is 111 FPS higher than Ultra and 124 FPS above High. The Low preset reaches 468 FPS, but the jump from Medium to Low (91 FPS) is smaller than the jump from High to Medium (111 FPS), suggesting diminishing returns at the extreme low end.

At 1440p, the pattern shifts. Ultra delivers 160 FPS, High reaches 168 FPS, and Medium jumps to 238 FPS. The Medium preset offers 78 FPS more than High, while High only provides 8 FPS over Ultra. At 4K, the differences compress further: Ultra averages 84 FPS, High reaches 88 FPS, and Medium hits 124 FPS. The Medium preset at 4K provides 40 FPS more than High, representing a 45% improvement.

The data suggests Medium is the sweet spot across all resolutions. At 1080p, Medium's 377 FPS average with a minimum of 320 FPS ensures smooth gameplay even during intense simulation moments. At 1440p, Medium's 238 FPS average with a 202 FPS minimum keeps well above typical high-refresh-rate monitors. At 4K, Medium's 124 FPS average with a 106 FPS minimum provides excellent visual quality without sacrificing responsiveness.

High settings are viable for users prioritizing visual fidelity, with 266 FPS at 1080p, 168 FPS at 1440p, and 88 FPS at 4K. The Ultra preset, while offering the highest visual quality, shows the smallest performance advantage over High — only 13 FPS at 1080p, 8 FPS at 1440p, and 4 FPS at 4K. Given these marginal differences, High settings appear more sensible than Ultra unless absolute maximum visual quality is required.

How This Combo Ranks

The combo achieves a rank of 41 out of 3002 tested combinations, positioning it in the 98.6th percentile of all configurations. This top-tier placement reflects the synergy between the Ryzen 9 9900X3D's strong multi-threaded performance and the RTX 5090's massive compute capabilities. The CPU's 3DMark max-thread score of 13,795 and Cinebench R23 multi-core score of 47,737 indicate substantial headroom for simulation workloads, while the GPU's Passmark G3D score of 39,650 demonstrates dominant graphics processing power.

The CPU itself ranks in the 91st percentile against all CPUs, with an average benchmark score of 54,762. Its nearest rivals show how close the competition is at this performance tier: the Intel Core Ultra 5 245KF scores 55,093 (0.6% higher), the Intel Core Ultra 5 245K scores 54,053 (1.3% lower), the Intel Xeon 6505P scores 53,701 (2% lower), and the Intel Core i7-14700F scores 53,620 (2.1% lower). This clustering indicates the 9900X3D sits in a highly competitive performance band where tiny percentage differences separate top-tier processors.

The GPU ranks in the 92nd percentile against all GPUs, with an average benchmark score of 79,842. Its nearest rivals include the NVIDIA Tesla P100 PCIe 16 GB at 79,605 (0.3% higher), the Tesla P100 PCIe 12 GB at 79,396 (0.6% higher), the AMD Radeon RX 6850M XT at 78,940 (1.1% higher), and the AMD Radeon Pro Vega 64X at 80,959 (1.4% lower). The RTX 5090's positioning among these competitors highlights its exceptional compute density, though the delta percentages are remarkably small given the architectural differences.

The 41st rank out of 3002 combos suggests that while this pairing is exceptionally fast, there are 40 other combinations that deliver even higher frame rates in Pc Building Simulator. Given that the RTX 5090 is near the top of GPU performance charts and the 9900X3D is a high-end 12-core processor, the limiting factor for achieving a higher rank likely lies in the game's engine behavior rather than raw hardware capability.

GPU Role

The NVIDIA GeForce RTX 5090 brings 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. This massive memory allocation is particularly relevant for Pc Building Simulator, a game that simulates component installation and system building — scenarios that may load many textures and 3D models simultaneously. The 92,200 million transistors on TSMC's 5 nm process provide the compute foundation, with 21,760 shading units, 680 texture mapping units, and 176 render output units.

The GPU's clock behavior shows a base frequency of 2017 MHz and a boost clock of 2407 MHz, with memory running at 1750 MHz (28 Gbps effective). The pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s indicate substantial fill-rate capabilities. In synthetic benchmarks, the GPU achieves a 3DMark Steel Nomad DX12 score of 18,355, a Geekbench OpenCL score of 334,370, and a Geekbench Vulkan score of 376,728. The Passmark G3D score of 39,650 places it in the 92nd percentile of all GPUs.

In Pc Building Simulator, the GPU's role appears to be secondary at lower resolutions. The 1080p Low preset delivers 468 FPS, which is likely beyond what the game's simulation logic can consistently feed. The GPU's 32 GB VRAM is far more than this game requires, making the memory capacity irrelevant for performance here — the game was released in 2019, before such capacities existed. The RTX 5090's compute power ensures it is never the bottleneck at 1080p or 1440p, but at 4K Ultra the 84 FPS average suggests the GPU is finally being challenged.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values span from 253 FPS at Ultra to 468 FPS at Low. The Medium preset delivers 377 FPS average with a minimum of 320 FPS and maximum of 433 FPS. High settings produce 266 FPS average. The progression from Ultra to Low shows a 215 FPS spread (253 to 468), representing an 85% performance increase when dropping from highest to lowest quality.

At 2560x1440, the averages range from 160 FPS at Ultra to 336 FPS at Low. Medium delivers 238 FPS average with a minimum of 202 FPS and maximum of 274 FPS. High settings produce 168 FPS average. The spread from Ultra to Low is 176 FPS, a 110% increase. Comparing 1080p to 1440p at the same settings, the FPS drops by: 13 FPS at Ultra (253 to 160, a 37% reduction), 14 FPS at High (266 to 168, a 37% reduction), 139 FPS at Medium (377 to 238, a 37% reduction), and 132 FPS at Low (468 to 336, a 28% reduction).

At 3840x2160, the averages range from 84 FPS at Ultra to 176 FPS at Low. Medium delivers 124 FPS average with a minimum of 106 FPS and maximum of 143 FPS. High settings produce 88 FPS average. The spread from Ultra to Low is 92 FPS, a 110% increase. Comparing 1440p to 4K at the same settings, the FPS drops by: 76 FPS at Ultra (160 to 84, a 48% reduction), 80 FPS at High (168 to 88, a 48% reduction), 114 FPS at Medium (238 to 124, a 52% reduction), and 160 FPS at Low (336 to 176, a 48% reduction).

The Medium preset consistently shows the widest gap between minimum and maximum FPS — 113 FPS at 1080p, 72 FPS at 1440p, and 37 FPS at 4K — indicating that this setting introduces more frame-time variance than other presets.

Resolution Scaling

The resolution scaling data reveals how the system's performance changes as pixel count increases. Moving from 1080p to 1440p (a 1.78x pixel increase) results in FPS drops of 37% at Ultra, 37% at High, 37% at Medium, and 28% at Low. Moving from 1440p to 4K (a 2.25x pixel increase) produces FPS drops of 48% at Ultra, 48% at High, 52% at Medium, and 48% at Low.

These scaling ratios are notably different from a purely GPU-bound scenario. If the RTX 5090 were the sole limiting factor, we would expect FPS to drop roughly proportionally to pixel count — meaning a 1.78x pixel increase should yield roughly 44% lower FPS, and a 2.25x increase should yield roughly 56% lower FPS. The measured drops are consistently smaller than these expectations, particularly at lower settings.

The 1080p to 1440p transition at Low settings shows only a 28% FPS drop despite the 1.78x pixel increase, strongly indicating that the CPU or game engine becomes the bottleneck at high frame rates. The 468 FPS at 1080p Low is likely approaching the game's logical update rate limit, meaning the GPU is waiting for the simulation to provide frames. At 4K, the 48-52% drops across settings suggest the GPU is becoming more relevant, but the consistent scaling pattern across all settings implies the game's rendering pipeline has inherent efficiency characteristics that differ from typical FPS titles.

The fact that Medium settings show a 52% FPS drop from 1440p to 4K — slightly higher than the 48% drops at other settings — hints that Medium may activate certain rendering features that scale more aggressively with resolution. The 106 FPS minimum at 4K Medium remains well above playable thresholds, suggesting that even the most demanding combination measured in this data does not push the RTX 5090 to its limits.

CPU Role

The AMD Ryzen 9 9900X3D contributes 12 cores and 24 threads based on the Zen 5 architecture, manufactured on TSMC's 4 nm process with 16,630 million transistors across a dual-chiplet design measuring 2x 70.6 mm². The processor runs at a 4.40 GHz base clock and boosts to 5.50 GHz, with a 120 W TDP. The 128 MB L3 cache provides substantial capacity for simulation workloads that exhibit data locality.

In Pc Building Simulator, the CPU's role is likely significant given the game's simulation-heavy nature. The 3DMark scores show strong scaling from 2 threads (2,512) to 16 threads (12,490) to max threads (13,795), indicating excellent multi-threading efficiency. The Cinebench R23 multi-core score of 47,737 versus single-core score of 6,739 demonstrates that the processor can leverage all 12 cores effectively, with a multi-core to single-core ratio of approximately 7.1x.

The 1080p Low preset achieving 468 FPS suggests the CPU can feed frames at extremely high rates, but the 28% FPS drop from 1080p to 1440p at Low (versus 37% at other settings) hints that at 1080p Low, the CPU may be approaching its frame-delivery ceiling. The Passmark multi-thread score of 56,154 and single-thread score of 4,646 place the CPU in the 91st percentile overall, with the nearest rivals showing less than 2.1% performance differences.

The architecture's 4 nm process and dual-chiplet layout with 128 MB L3 cache position this CPU as a high-end option for simulation games. The 89.6 GB/s memory bandwidth over dual-channel DDR5, combined with PCIe Gen 5 connectivity, ensures the CPU can communicate efficiently with the RTX 5090. However, the measured FPS data shows that even with this powerful CPU, the game's engine appears to cap frame rates around 468 FPS at 1080p Low, suggesting that the simulation logic itself — not the hardware — becomes the limiting factor at extreme frame rates.
