Pc Building Simulator

Pc Building Simulator is a simulation title that tasks players with assembling and troubleshooting virtual hardware, and the benchmark data for the Intel Core i5-14400F paired with the NVIDIA GeForce RTX 5090 reveals a system that is overwhelmingly GPU-bound at higher resolutions, yet shows surprising CPU sensitivity at 1080p. The combination of a 10-core, 16-thread processor with a 32 GB flagship graphics card produces frame rates ranging from a playable 83.2 FPS at 4K Ultra to a blistering 373.9 FPS at 1080p Low, with the data indicating that the RTX 5090 is the primary driver of performance in most scenarios, while the i5-14400F's 4.70 GHz boost clock becomes a more critical factor only when the resolution drops and the GPU workload lightens.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-14400F is a 10-core, 16-thread processor from the Core 14th Gen series, built on the Raptor Lake architecture with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. In Pc Building Simulator, a game that simulates the logical and physical act of constructing PCs, the CPU's role is substantial but not always the bottleneck. The processor's performance profile is solid, ranking in the 88th percentile against all CPUs with an average benchmark score of 32508. This places it in close competition with several mobile and desktop parts, including the Intel Core i7-12800H, which scores 32513 (a 0% delta), and the AMD Ryzen 5 PRO 7645, which scores 32446 (a 0.2% delta). The i5-14400F slightly outperforms the AMD Ryzen 7 250 and Intel Core i7-13705H, both of which score 32584 and 32586 respectively, showing a -0.2% delta.

The measured FPS data shows that at 1080p Low, the system achieves 373.9 FPS, which suggests that the CPU is capable of feeding the GPU with enough data to maintain very high frame rates. However, the core count and thread count become relevant when considering that Pc Building Simulator involves managing multiple simultaneous tasks, such as inventory systems, component installation logic, and OS-level simulations. The Cinebench R23 multicore score of 21914 and single-core score of 3093 indicate a balanced part, but the game's results at higher resolutions suggest that the CPU's 10 cores are not the limiting factor. The boost clock of 4.70 GHz is likely the more critical specification for this title, as the data shows that frame rates scale dramatically with resolution, implying that the CPU's single-threaded speed helps maintain high minimum frame rates at 1080p, even when the GPU is not fully stressed.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-14400F and NVIDIA GeForce RTX 5090 achieves a rank of 31 out of 1769 tested combos in Pc Building Simulator. This places the pairing in the top 1.75% of all systems tested, indicating exceptional performance for this specific game. The rank is impressive given that the i5-14400F is a mid-range desktop processor, while the RTX 5090 is a flagship GPU. The data suggests that the combo's high ranking is primarily due to the GPU's immense computational power, as the CPU's own benchmark percentile of 88 is lower than the GPU's percentile of 94. The rank of 31 out of 1769 combos means that only 30 other CPU-GPU pairings produced higher average FPS in this title, and those likely feature more powerful processors, such as high-end Core i9 or Ryzen 9 chips, paired with the same or similar GPUs. The delta between the i5-14400F and its nearest CPU rivals is minimal, with differences of only 0.2% or less in average benchmark scores, suggesting that the CPU is not a significant differentiator in this combo's ranking. Instead, the data implies that the RTX 5090's raw performance is what pushes this combo to the 31st spot, and any CPU with comparable single-threaded performance would yield similar results.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling across resolutions provides clear evidence of where the bottleneck lies. At 1080p Ultra, the system produces 257.4 FPS, but at 1440p Ultra, the frame rate drops to 164 FPS, a reduction of 36.3%. Moving to 4K Ultra, the FPS falls to 83.2, which is a further 49.3% drop from 1440p. This steep decline with increasing resolution is a classic sign of GPU-bound performance. The RTX 5090, with its 32 GB of GDDR7 memory and 1.79 TB/s bandwidth, is the component handling the increased pixel workload, and the data shows that its performance scales predictably with resolution. However, at 1080p Low, the system hits 373.9 FPS, and at 1080p Medium, it reaches 329.3 FPS, while at 1080p High it is 268.6 FPS. The fact that 1080p Low is only 13.5% faster than 1080p Medium, but 39.2% faster than 1080p High, suggests that at lower resolutions, the CPU's ability to process game logic and draw calls becomes more relevant. The i5-14400F's 4.70 GHz boost clock and 20 MB of shared L3 cache help maintain high frame rates at 1080p, but the data indicates that the GPU is still the primary limiter, as even at 1080p Low, the system is not hitting the 500+ FPS that a purely CPU-bound scenario might produce.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of the system's performance. At 1920x1080, the average FPS ranges from 373.9 on Low settings to 257.4 on Ultra. The Medium preset yields 329.3 FPS, while High produces 268.6 FPS. This shows a clear scaling pattern where each settings tier reduces performance by roughly 20-25%, with the exception of the jump from High to Ultra, which is only a 4.2% drop. At 2560x1440, the average FPS drops to 318.7 on Low, 239.5 on Medium, 173 on High, and 164 on Ultra. The scaling from Low to Medium is a 24.8% reduction, while High to Ultra is a 5.2% reduction, indicating that the Ultra preset at 1440p is not significantly more demanding than High. At 3840x2160, the average FPS is 176.6 on Low, 125.5 on Medium, 87.6 on High, and 83.2 on Ultra. The drop from Low to Medium is 28.9%, and from High to Ultra is 5.0%. The data shows that the RTX 5090 can handle 4K Ultra at 83.2 FPS, which is above the 60 FPS threshold for smooth gameplay, and at 4K High it achieves 87.6 FPS. The most notable finding is that the difference between High and Ultra settings is consistently small across all resolutions (4-5%), suggesting that the Ultra preset offers diminishing returns for the additional GPU load. The system never drops below 83.2 FPS in any tested configuration, indicating that the combo is capable of running the game at maximum settings at 4K with playable frame rates.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5090 is a flagship graphics card based on the Blackwell 2.0 architecture, featuring 32 GB of GDDR7 memory on a 512-bit bus, providing a bandwidth of 1.79 TB/s. The GPU has a base clock of 2017 MHz and a boost clock of 2407 MHz, with 21760 shading units and 680 tensor cores. In Pc Building Simulator, the GPU's role is primarily to render the game's interface, 3D components, and system visualizations. The 32 GB VRAM is far more than the game requires, as Pc Building Simulator is not a graphically intensive title, but the data shows that the GPU's raw compute power is what drives the high frame rates. The RTX 5090's 104.8 TFLOPS of FP32 performance and 423.6 GPixel/s pixel rate are likely the key specs that allow the system to achieve 373.9 FPS at 1080p Low. The GPU's benchmark scores are exceptionally high, with a Passmark G3D score of 39650 and a 3DMark Steel Nomad DX12 score of 14411, placing it in the 94th percentile of all GPUs. The nearest rivals include the RTX 5090 D with a score of 84241 (0.1% delta) and the RTX 5050 Mobile with a score of 84171 (0.2% delta), but the RTX 5090's performance is clearly superior to these parts. The GPU's 575 W TDP and suggested PSU of 950 W indicate that it requires substantial power, but the benchmark results show that this power translates directly into frame rate performance, particularly at 4K where the system maintains 83.2 FPS on Ultra settings.

Settings Recommendations

Based on the measured FPS data, the best experience for this combo is achieved at 1440p with Ultra settings, which delivers 164 FPS. This resolution offers a balance between visual fidelity and frame rate, as the difference between High and Ultra is only 5.2% at this resolution (173 to 164 FPS), making Ultra the obvious choice for maximum quality without a significant performance penalty. At 4K, Ultra settings are also viable at 83.2 FPS, but if players prefer higher frame rates, dropping to High settings yields 87.6 FPS, a negligible 5.0% improvement. The data shows that the Low preset provides disproportionately high frame rates (176.6 FPS at 4K and 373.9 FPS at 1080p), but this comes at the cost of visual quality and is not recommended for a game that is not graphically demanding. For players with 1080p monitors, Ultra settings at 257.4 FPS are the best choice, as the GPU has more than enough headroom to run the game at maximum settings without any concerns about frame rate drops. The Medium preset offers a middle ground, but the small performance difference between Medium and High (329.3 vs 268.6 FPS at 1080p) suggests that High is the better value in terms of visual quality per FPS lost. Overall, the data indicates that this system can handle the game's maximum settings at any resolution, with 1440p Ultra providing the most balanced experience for high-refresh-rate displays.
