# Pc Building Simulator — AMD Ryzen 9 9900X + NVIDIA GeForce RTX 5090 D

The AMD Ryzen 9 9900X paired with the NVIDIA GeForce RTX 5090 D delivers a benchmark suite that is almost entirely GPU-bound at lower resolutions, then transitions to a more balanced profile as pixel count rises. Across the twelve measured configurations in Pc Building Simulator, this combo produces average frame rates ranging from 89 FPS at 4K Ultra to 471 FPS at 1080p Low, with the data showing a clear pattern of diminishing returns as settings increase. The combo ranks 8th out of 3,002 tested combinations, placing it in the top 0.3% of all systems in the database for this title.

Resolution Scaling

The measured FPS data reveals a steep and consistent drop as resolution scales from 1920x1080 to 3840x2160. At High settings, the average frame rate moves from 284 FPS at 1080p down to 179 FPS at 1440p, then to 94 FPS at 4K. This represents a 37% reduction from 1080p to 1440p, and a further 47% reduction from 1440p to 4K. The total decline from 1080p High to 4K High is 67%, which is a substantial hit that points toward the GPU becoming the primary limiting factor at higher resolutions.

Low settings tell an even more dramatic story. At 1080p Low, the system produces 471 FPS, which drops to 358 FPS at 1440p (a 24% decrease) and then to 187 FPS at 4K (a 48% decrease from 1440p). The 1080p to 4K delta at Low settings is 60%, slightly less severe than at High settings, suggesting that at Low settings the CPU is still contributing meaningfully to frame delivery at 1080p, but the GPU constraint becomes dominant as resolution climbs.

Medium settings show the least severe relative scaling between 1440p and 4K. At 1080p Medium, the system hits 402 FPS; at 1440p Medium, 254 FPS; and at 4K Medium, 133 FPS. The 1080p-to-1440p drop is 37%, while the 1440p-to-4K drop is 48%. Ultra settings follow a similar pattern to High: 270 FPS at 1080p, 171 FPS at 1440p, and 89 FPS at 4K, with the same percentage reductions as High settings.

The frame rate scaling suggests that at 1080p, the Ryzen 9 9900X's 12 cores and 24 threads are capable of feeding the RTX 5090 D well beyond what most displays can refresh, especially at Low and Medium settings. The 471 FPS at 1080p Low and 402 FPS at 1080p Medium indicate that the CPU is not a bottleneck at this resolution. However, the sharp drop-off at 4K — where even Low settings produce only 187 FPS — demonstrates that the GPU's rendering workload, driven by the 32 GB of GDDR7 memory and 512-bit bus, becomes the dominant constraint.

GPU Role

The NVIDIA GeForce RTX 5090 D is the clear performance driver in this configuration, particularly at higher resolutions. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is more than sufficient for Pc Building Simulator's asset streaming and scene complexity. The GPU's boost clock of 2407 MHz, running on the Blackwell 2.0 architecture with 21,760 shading units, explains why frame rates remain high even at 1440p Ultra (171 FPS) and 4K High (94 FPS).

The RTX 5090 D's benchmark scores reinforce its position. Its 3DMark Steel Nomad DX12 score of 14,326 and PassMark G3D score of 44,065 place it in the 92nd percentile among all GPUs. The GPU's nearest rivals in the database include the AMD Radeon RX 6650M XT (which scores 1.1% higher on average), the AMD Radeon RX 6850M XT (1.6% lower), and the NVIDIA Tesla P100 variants (2.1% and 2.4% lower). This tight clustering with mobile and data-center parts is noteworthy — the RTX 5090 D's desktop-class performance is comparable to those parts on synthetic benchmarks, but in this game's measured FPS, the GPU clearly excels at 4K where memory bandwidth and raw fill rate matter most.

At 4K Ultra, the system produces 89 FPS, which is the lowest measured result across all configurations. The gap between 4K Ultra (89 FPS) and 4K High (94 FPS) is just 5 FPS, while the jump from 4K Medium (133 FPS) to 4K High (94 FPS) is 39 FPS. This suggests that the Ultra preset introduces a significant rendering cost that outweighs its visual benefit, likely due to effects that heavily tax the GPU's 176 ROPs and 680 TMUs. The pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are substantial, yet the Ultra preset at 4K still manages to bring the system to just under 90 FPS.

Settings Recommendations

The measured data provides clear guidance on which presets deliver the best balance of performance and visual quality. At 4K, Medium settings (133 FPS average, with a min of 113 and max of 153) offer the best experience — it is 39 FPS faster than High and 44 FPS faster than Ultra, while still providing a frame rate that comfortably exceeds standard 60 Hz displays. The 4K Ultra preset at 89 FPS is playable but leaves little headroom for frame time spikes, and the 5 FPS gain from High to Ultra is not justified by the performance cost.

At 1440p, Medium settings (254 FPS average, min 216, max 292) represent a sweet spot. The system can push 171 FPS at Ultra, which is still excellent for high-refresh monitors, but Medium provides a 48% improvement over Ultra while likely maintaining most visual fidelity. At 1440p Low (358 FPS), the system is clearly CPU-limited at this resolution, as the GPU has ample headroom; this configuration is best for competitive play or maximum frame rate targets.

At 1080p, the situation is reversed — all presets produce frame rates above 270 FPS, with Low hitting 471 FPS and Medium reaching 402 FPS. The Ultra preset at 270 FPS is still far beyond what most 1080p monitors can display, so users with standard 144 Hz or 240 Hz panels should select Ultra for maximum visual quality without sacrificing smoothness. The 1080p Medium result (402 FPS) with a min of 342 and max of 462 shows that the system maintains high minimum frame rates even at this resolution.

How This Combo Ranks

The combo holds the 8th position out of 3,002 tested combinations in Pc Building Simulator, which places it in the 99.7th percentile of all systems. This ranking reflects the synergy between the Ryzen 9 9900X and RTX 5090 D, where the CPU's strong single-threaded and multi-threaded performance complements the GPU's raw rendering power.

The CPU's own benchmark data shows it sits in the 92nd percentile among all CPUs, with an average benchmark score of 57,498. Its nearest rivals include the AMD EPYC 9015 (0.1% lower score), AMD EPYC 7313 (0.2% higher), Intel Core i9-14900 (1.1% higher), and Intel Xeon Platinum 8260M (1.4% higher). The Ryzen 9 9900X's Cinebench R23 scores — 32,172 multi-core and 2,253 single-core — indicate strong performance that avoids bottlenecking the GPU in this simulation title.

The GPU's 92nd percentile ranking, with an average benchmark score of 77,712, is similarly positioned among its peers. The fact that both components rank in the 92nd percentile of their respective categories, yet the combo ranks 8th out of 3,002, suggests that this pairing is particularly well-suited to Pc Building Simulator's workload. The game's simulation nature likely benefits from the CPU's 12 cores and 24 threads, while the GPU's 32 GB memory capacity handles the game's asset-heavy scenes without swapping.

CPU Role

The AMD Ryzen 9 9900X, based on the Zen 5 architecture (Granite Ridge codename), contributes significantly to this combo's performance, particularly at lower resolutions where the GPU is less stressed. With 12 cores and 24 threads, a base clock of 4.40 GHz and boost clock of 5.60 GHz, the CPU provides the computational headroom needed to maintain high frame rates at 1080p and 1440p. The 64 MB of L3 cache and 1 MB L2 cache per core ensure that game logic and simulation data remain close to the execution units.

The CPU's benchmark results illustrate its capability. The Geekbench multi-core score of 22,174 and single-core score of 3,010 are strong, while the Cinebench R23 multi-core score of 32,172 confirms that the 12-core configuration scales well under threaded workloads. The 3DMark 16-thread score of 12,552 and max-thread score of 13,929 show that the CPU maintains performance as thread count increases, which is relevant for a simulation game that may spawn multiple game-object update threads.

The CPU's 120 W TDP and 4 nm process node (TSMC) keep power efficiency high, though the 89.6 GB/s memory bandwidth on DDR5 dual-channel may be a mild constraint in memory-heavy scenes. The PCIe Gen 5 interface with 24 lanes ensures that the RTX 5090 D has ample bandwidth for data transfer, and the integrated Radeon Graphics provide a fallback display output.

At 1080p Low, the system produces 471 FPS, which is likely near the CPU's maximum frame delivery capability for this game. The fact that 1080p Medium (402 FPS) and 1080p High (284 FPS) show diminishing returns as GPU load increases indicates that the CPU is not the bottleneck at this resolution — the GPU's rendering pipeline is. However, at 4K, the CPU's role diminishes further; the 4K results (89-187 FPS across presets) are almost entirely GPU-bound, as the RTX 5090 D's fill rate and memory bandwidth become the limiting factors.
