Pc Building Simulator

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4090 combination delivers exceptionally high frame rates in Pc Building Simulator, a simulation title that scales dramatically with both resolution and graphical settings. The measured data places this combo at rank 15 out of 1769 tested combinations, placing it in the top 1% of all systems evaluated. This pairing of a 12-core Zen 5 processor with the flagship Ada Lovelace GPU produces a performance profile where the CPU becomes the dominant factor at lower resolutions, while the GPU takes over as the primary constraint at higher settings.

Resolution Scaling

The frame rate progression across resolutions reveals a classic bottleneck shift. At 1080p with Low settings, the combo produces 468.4 FPS, which drops to 327.5 FPS at 1440p and further to 170.6 FPS at 4K. This represents a 63.6% reduction from 1080p to 4K at Low settings, indicating that the GPU is heavily loaded by the pixel count increase. The RTX 4090, with its 24 GB of GDDR6X memory and 1.01 TB/s bandwidth, can handle the geometry and texture workloads, but the sheer pixel throughput at 4K inevitably limits performance.

At Ultra settings, the scaling pattern shifts. The combo achieves 249.9 FPS at 1080p, 154.1 FPS at 1440p, and 84.5 FPS at 4K. The drop from 1080p to 4K at Ultra is 66.2%, slightly larger than at Low settings. This suggests that the higher graphical fidelity settings, which likely include more complex lighting and shadow calculations, amplify the GPU workload more than the resolution increase alone. The RTX 4090's 128 ray tracing cores and 512 tensor cores are engaged more heavily at Ultra, reinforcing the GPU-bound nature of the high-fidelity presets.

The Medium and High settings show intermediate behavior. At 1080p Medium, the combo hits 366.9 FPS, which falls to 230.5 FPS at 1440p and 123.6 FPS at 4K. High settings produce 259.4 FPS at 1080p, 165.9 FPS at 1440p, and 89.2 FPS at 4K. The consistent pattern across all settings is that 4K performance sits between 84.5 and 170.6 FPS, meaning even the most demanding preset maintains playable frame rates. The data indicates that Pc Building Simulator is not a title that can fully stress the RTX 4090 at 1080p, where the CPU's 5.60 GHz boost clock and 24 threads become the limiting factor.

How This Combo Ranks

The comboRankInGame field places this system at rank 15 out of 1769 tested combinations. This top 1% placement reflects the synergy between the Ryzen 9 9900X and RTX 4090. The CPU's average benchmark score of 54450 puts it in the 94th percentile of all CPUs, with its closest rival being the AMD Ryzen 9 9900X3D at 54681 (a -0.4% delta) and the Intel Core Ultra 5 245KF at 55421 (a -1.8% delta). The GPU, meanwhile, achieves an average benchmark score of 66473, placing it in the 91st percentile of all GPUs, with its nearest rival being the NVIDIA Tesla T4 at 66733 (a -0.4% delta).

The rank of 15 indicates that only 14 other combos in the database outperform this pairing in Pc Building Simulator specifically. Given the game's simulation genre, which often relies on single-threaded performance for game logic, the Ryzen 9 9900X's 3dmark_single_thread score of 1286 and passmark_single_thread score of 4672 likely contribute significantly to this high ranking. The data suggests that the combo's position is not merely a function of raw GPU power but also the CPU's ability to feed the RTX 4090 with sufficient draw calls and simulation updates. The deltaPct values for the CPU's rivals show that the 9900X sits within 1.8% of its nearest competitors, meaning the rank is achieved through balanced component selection rather than one part dominating.

Measured FPS Breakdown

At 1920x1080 resolution, the combo delivers a wide range of performance depending on settings. Low settings produce 468.4 FPS, which is the highest measured value across all configurations. Medium settings yield 366.9 FPS, High settings 259.4 FPS, and Ultra settings 249.9 FPS. The gap between High and Ultra is relatively small at 9.5 FPS, suggesting that the Ultra preset adds minimal additional GPU load at this resolution. The data shows that at 1080p, the Ryzen 9 9900X's 12 cores and 24 threads are sufficient to keep the RTX 4090 well-fed, even at the most demanding settings.

Moving to 2560x1440, the frame rates scale down predictably. Low settings produce 327.5 FPS, Medium 230.5 FPS, High 165.9 FPS, and Ultra 154.1 FPS. The percentage drop from 1080p to 1440p ranges from 30.1% at Low (468.4 to 327.5) to 38.3% at Ultra (249.9 to 154.1). This indicates that the GPU becomes progressively more involved as resolution increases, with the RTX 4090's 16384 shading units and 512 texture mapping units handling the additional pixel workload.

At 3840x2160, the combo's performance remains strong but clearly GPU-bound. Low settings achieve 170.6 FPS, Medium 123.6 FPS, High 89.2 FPS, and Ultra 84.5 FPS. The difference between High and Ultra at 4K is only 4.7 FPS, the smallest gap across all resolutions. This suggests that at 4K, the GPU's 24 GB of GDDR6X memory and 384-bit bus width become saturated, and the additional settings in Ultra provide diminishing returns. The RTX 4090's 82.58 TFLOPS of FP32 compute is heavily utilized at this resolution, with the game's simulation logic taking a backseat to pixel processing.

GPU Role

The NVIDIA GeForce RTX 4090 plays a critical role in this combo's performance, particularly at higher resolutions and settings. The GPU operates with a base clock of 2235 MHz and a boost clock of 2520 MHz, paired with 24 GB of GDDR6X memory running at 21 Gbps effective. This memory configuration yields a bandwidth of 1.01 TB/s across a 384-bit bus, which is essential for handling the texture and geometry data in Pc Building Simulator's detailed PC component models.

The GPU's benchmark scores reinforce its capability. In 3dmark_steel_nomad_dx12, the RTX 4090 scores 9223, and its passmark_g3d score is 38194, placing it in the 91st percentile of all GPUs. The nearest rival, the NVIDIA Tesla T4, scores 66733 on average, a mere 0.4% difference, indicating that the RTX 4090 sits at the very top of GPU performance. The GPU's 128 ray tracing cores and 512 tensor cores provide substantial compute headroom, though Pc Building Simulator likely does not heavily utilize these specialized units given its simulation focus.

At 4K Ultra, the RTX 4090 produces 84.5 FPS, which is the lowest measured value in the dataset. This indicates that the GPU is the limiting factor at this setting, as the 24 GB memory buffer and 609 mm² die are fully engaged. The GPU's 443.5 GPixel/s pixel rate and 1,290.2 GTexel/s texture rate are sufficient for the game's visual demands, but the sheer pixel count at 3840x2160 combined with Ultra settings pushes the card to its limits. The data shows that the RTX 4090's performance headroom is best utilized at 1440p, where it can deliver between 154.1 and 327.5 FPS depending on settings.

CPU Role

The AMD Ryzen 9 9900X serves as the foundation for this combo, providing the processing power necessary to drive the RTX 4090 at high frame rates. The CPU features 12 cores and 24 threads based on the Zen 5 architecture, with a base clock of 4.40 GHz and a boost clock of 5.60 GHz. This configuration, built on a 4 nm process at TSMC, delivers substantial single-threaded and multi-threaded performance that is critical for a simulation game like Pc Building Simulator.

The CPU's benchmark scores demonstrate its capability. In cinebench_r23_multicore, the 9900X scores 46438, and in cinebench_r23_singlecore it scores 6555. The 3dmark_single_thread score of 1286 and passmark_single_thread score of 4672 indicate strong single-core performance, which is essential for game logic and physics calculations in simulation titles. The CPU's 64 MB of shared L3 cache and 1 MB per-core L2 cache provide low-latency access to frequently used data, further enhancing its responsiveness in real-time simulations.

At 1080p Low settings, the combo achieves 468.4 FPS, which is likely CPU-bound. The Ryzen 9 9900X's 24 threads can handle the game's simulation updates, but the frame rate ceiling is reached when the CPU cannot issue draw calls fast enough to keep the RTX 4090 fully occupied. The CPU's 89.6 GB/s dual-channel DDR5 memory bandwidth and PCIe Gen 5 interface with 24 lanes ensure that data flows efficiently between the processor, memory, and GPU. The 9900X's 94th percentile ranking among all CPUs, with an average benchmark score of 54450, places it just 0.4% behind the Ryzen 9 9900X3D and 1.8% behind the Intel Core Ultra 5 245KF, showing that it is a top-tier processor even among its closest rivals.
