Pc Building Simulator

The AMD Ryzen 9 5950X and NVIDIA GeForce RTX 4090 combo delivers exceptional frame rates in Pc Building Simulator, but the performance profile reveals a system that is strongly GPU-bound at higher resolutions while showing signs of CPU limitation at 1080p. The data shows that this pairing, ranked 64th out of 1769 tested combos, offers a remarkably smooth experience across all settings, though the scaling patterns indicate that the RTX 4090 is the primary driver of performance in most scenarios.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but consistent with a GPU-limited workload. At Low settings, performance falls from 347.8 FPS at 1920x1080 to 174.2 FPS at 3840x2160, a reduction of exactly half. This 50% drop strongly suggests that the RTX 4090's rendering throughput is the limiting factor, as the workload scales almost directly with pixel count. The pattern holds across other settings: Medium drops from 310 FPS to 122.1 FPS (a 60.6% reduction), while High falls from 259.1 FPS to 84.9 FPS (a 67.2% reduction).

The Ultra preset shows the most dramatic scaling loss, going from 249.3 FPS at 1080p to just 82.3 FPS at 4K, a 67% decline. This steeper drop at higher quality settings indicates that the additional graphical effects and shading complexity at Ultra amplify the GPU's workload more than the raw resolution increase alone. Interestingly, the gap between 1080p and 1440p is much smaller than the gap between 1440p and 4K. At Low settings, 1440p delivers 299.9 FPS versus 347.8 FPS at 1080p, a modest 13.8% reduction, while moving from 1440p to 4K costs another 41.9%. This nonlinear scaling is typical of a GPU that still has headroom at lower resolutions but becomes increasingly saturated as pixel count rises.

The data indicates that at 1080p, the system is partially CPU-limited, particularly at Low and Medium settings where frame rates exceed 300 FPS. The Ryzen 9 5950X, with its 16 cores and 32 threads, provides enough single-thread performance to keep up, but the ceiling appears to be around 347.8 FPS, suggesting that even this flagship processor cannot fully feed the RTX 4090 at the lowest settings. At 4K, however, the GPU becomes the clear bottleneck, with all settings showing frame rates well below what the CPU could theoretically support.

CPU Role

The Ryzen 9 5950X's architecture plays a crucial role in this game's performance. With 16 cores and 32 threads based on Zen 3, this processor offers substantial multi-threaded capability, which is reflected in its Cinebench R23 multicore score of 38607 and Geekbench multicore score of 12084. The 3.40 GHz base clock and 4.90 GHz boost clock provide strong single-thread performance, evidenced by the 3dmark_single_thread score of 944 and Passmark single-thread score of 3470.

In Pc Building Simulator, a simulation title that typically relies on physics calculations and game logic, the CPU's thread count and clock speed are both relevant. The benchmark results show that at 1080p Low settings, the system achieves 347.8 FPS, which likely approaches the practical ceiling for this processor's single-thread throughput. The 3dmark_2_threads score of 1856 and 3dmark_4_threads score of 3595 indicate that the CPU handles lightly-threaded workloads well, but the game appears to scale with resolution in a way that suggests the GPU dominates overall performance.

The processor's 64 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide adequate data throughput for the simulation's asset streaming. The Ryzen 9 5950X's percentile rank of 93 among all CPUs, with an average benchmark score of 49062, places it in the top tier of processors. Its nearest rivals include the Intel Core i5-14600K (deltaPct -0.2%) and Intel Core i5-14600KF (deltaPct -0.6%), showing that the 5950X is statistically comparable to these newer chips in overall benchmark scores, despite being from an older generation.

GPU Role

The NVIDIA GeForce RTX 4090 is clearly the dominant component in this pairing. With 24 GB of GDDR6X memory on a 384-bit bus delivering 1.01 TB/s bandwidth, the GPU has ample resources for high-resolution textures and effects. The 16384 shading units, 512 TMUs, and 176 ROPs provide massive raw compute power, translating to an FP32 throughput of 82.58 TFLOPS. The boost clock of 2520 MHz ensures that this hardware is fully utilized during gaming workloads.

The GPU's benchmark scores underscore its capability: a Passmark G3D score of 38194 and Geekbench OpenCL score of 317684 place it in the 91st percentile among all GPUs. Its nearest rivals in benchmark averages include the NVIDIA Tesla T4 (deltaPct -0.4%) and AMD Radeon Pro Vega 56 (deltaPct -0.9%), though these comparisons are based on synthetic workloads rather than gaming performance. The RTX 4090's 5 nm process node from TSMC, with 76,300 million transistors on a 609 mm² die, represents the modern of GPU manufacturing at the time of its release.

In Pc Building Simulator, the RTX 4090's performance scales predictably with resolution. At 4K Ultra, it delivers 82.3 FPS, which is sufficient for smooth gameplay but shows the GPU's limits under maximum load. The transition from Low to Ultra at 4K costs 91.9 FPS (from 174.2 to 82.3), demonstrating that the quality presets significantly impact the GPU's workload. The 24 GB VRAM is more than sufficient for this simulation, as even at 4K Ultra the game does not appear to experience memory-related stutters or texture pop-in based on the consistent average frame rates.

Measured FPS Breakdown

At 1920x1080 resolution, the system delivers consistently high frame rates across all settings. Low preset averages 347.8 FPS, Medium averages 310 FPS, High averages 259.1 FPS, and Ultra averages 249.3 FPS. The difference between Low and Ultra is 98.5 FPS, representing a 28.3% performance penalty for maximum quality. The relatively small gap between High (259.1 FPS) and Ultra (249.3 FPS) of only 9.8 FPS suggests that the Ultra preset's additional effects have diminishing returns at this resolution.

Moving to 2560x1440, the frame rates remain impressive but show a clear step down. Low averages 299.9 FPS, Medium averages 235.1 FPS, High averages 161.5 FPS, and Ultra averages 158.3 FPS. The transition from 1080p to 1440p costs 13.8% at Low (347.8 to 299.9) but 37.7% at High (259.1 to 161.5). At 1440p, the gap between High and Ultra narrows to just 3.2 FPS, indicating that the GPU is becoming the limiting factor even at this mid-range resolution.

At 3840x2160, the system still delivers playable frame rates across the board. Low averages 174.2 FPS, Medium averages 122.1 FPS, High averages 84.9 FPS, and Ultra averages 82.3 FPS. The drop from 1440p to 4K is substantial: at Low, performance falls by 41.9% (299.9 to 174.2), while at Ultra it falls by 48% (158.3 to 82.3). Notably, the difference between High and Ultra at 4K is only 2.6 FPS, suggesting that the Ultra preset's additional graphical features have minimal impact on frame rate once the GPU is heavily loaded.

Settings Recommendations

For 4K gaming, the data recommends the High preset as the optimal balance. High averages 84.9 FPS at 3840x2160, which is only 2.6 FPS below Ultra's 82.3 FPS, but the lower settings likely reduce visual noise without sacrificing meaningful quality. The Low preset at 4K delivers 174.2 FPS, which is more than double the High preset's frame rate, but the visual quality trade-off is substantial. Medium at 122.1 FPS offers a middle ground for players who prioritize smoothness over fidelity.

At 1440p, the High preset (161.5 FPS) is the recommended choice, as it delivers over 60% higher frame rates than the 4K equivalent while maintaining strong visual quality. Players with high refresh rate monitors (144Hz or above) should consider the Medium preset at 235.1 FPS, which exceeds the refresh rate of most displays and provides a significant buffer for frame time consistency. The Ultra preset at 158.3 FPS is only 3.2 FPS slower than High, so players who want maximum quality should not hesitate to select it.

For 1080p, the Ultra preset (249.3 FPS) is the clear recommendation, as it delivers frame rates well above 240Hz thresholds while providing the best visual experience. The difference between High (259.1 FPS) and Ultra (249.3 FPS) is negligible at 9.8 FPS, so there is no reason to compromise on quality at this resolution. Even the most demanding preset configurations will not stress this system at 1080p, as all settings deliver at least 249.3 FPS. The Medium preset's 310 FPS and Low's 347.8 FPS are only relevant for competitive play where maximum frame rates are prioritized over visual fidelity.
