Pc Building Simulator

Pc Building Simulator presents an interesting case study when paired with the Intel Core i7-14700K and AMD Radeon RX 5700 XT. This simulation title, released in 2019, is not typically demanding on hardware, yet the measured data reveals a clear performance hierarchy that depends heavily on both resolution and graphics settings. The combination’s overall rank of 1255 out of 1769 tested combos suggests it is a mid-to-lower-tier performer in this specific game, which is surprising given the strength of the flagship-class CPU in the setup. The following analysis breaks down how each component contributes to the final frame rates.

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

The Intel Core i7-14700K is a 20-core, 28-thread processor based on the Raptor Lake architecture. It operates with a base clock of 3.40 GHz and can boost up to 5.60 GHz, which are impressive specifications for any workload. The CPU's benchmark results are exceptionally strong, with a Cinebench R23 multi-core score of 44534 and a single-core score of 6287. This places the processor in the 96th percentile of all CPUs, indicating that it is one of the more powerful chips available. The average benchmark score of 70074 is nearly identical to its closest rival, the Intel Core i7-14700KF, which scores 70104, showing a negligible 0% deltaPct difference.

However, in the context of Pc Building Simulator, this massive CPU power appears to be largely underutilized. The game's simulation logic is unlikely to stress a 20-core processor, and the data supports this. At 1080p with Low settings, the system achieves 225 FPS, which is an extremely high frame rate that often indicates a CPU-bound scenario. Yet, when we look at the scaling from 1080p Low to 4K Low, the frame rate drops to 73.9 FPS, a reduction of over 67%. This significant drop when resolution increases suggests that the CPU is not the primary limiting factor at lower resolutions; instead, the GPU takes over as the bottleneck as pixel count rises. The CPU’s high single-thread performance, evidenced by its 633 score in Cinebench R15, ensures that it never becomes a hindrance, but the game simply does not require the multi-core muscle that the i7-14700K provides.

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

The AMD Radeon RX 5700 XT is an older graphics card, based on the RDNA 1.0 architecture and the Navi 10 chip. It features 8 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 448.0 GB/s. The GPU's clocks are set at a base of 1605 MHz and a boost of 1905 MHz, with a game clock of 1755 MHz. In terms of raw compute, it offers 9.754 TFLOPS of FP32 performance. Its benchmark scores are solid, with a Passmark G3D score of 16277 and a Geekbench OpenCL score of 77773, placing it in the 68th percentile of all GPUs. Its average benchmark score of 24731 is nearly identical to the NVIDIA RTX A5000 Mobile, which is only 0.1% behind.

This GPU is the clear bottleneck in this configuration for Pc Building Simulator. The evidence is stark when comparing frame rates across different resolutions at the same settings. For instance, at High settings, the system produces 112.7 FPS at 1080p, but this plummet to 68.5 FPS at 1440p and 39.9 FPS at 4K. This performance curve is characteristic of a GPU that is being overwhelmed by increasing pixel counts. The 8 GB of VRAM may also be a factor at 4K Ultra, where memory demands are highest, though the frame rate of 37.4 FPS suggests the core compute limits are the primary constraint. The GPU's 64 ROPs and 2560 shading units are simply not sufficient to maintain high frame rates at 4K in this title, regardless of the CPU's capability.

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

The FPS scaling across resolutions provides a textbook example of a GPU-bound system. At Low settings, the transition from 1080p (225 FPS) to 1440p (143.2 FPS) represents a 36.4% drop in performance. Moving from 1440p to 4K (73.9 FPS) results in an even more drastic 48.4% drop. This progressive decline is a hallmark of a GPU that is running out of pixel processing power. The CPU is clearly capable of feeding the GPU at all resolutions, as evidenced by the high frame rates at 1080p.

When looking at Ultra settings, the trend is similar but with lower absolute numbers. The frame rate goes from 105.8 FPS at 1080p to 68.6 FPS at 1440p and finally to 37.4 FPS at 4K. The drop from 1080p to 1440p is 35.2%, which is consistent with the Low settings pattern. This consistency across settings further confirms that the resolution is the dominant variable, and the component handling that variable is the GPU. The data clearly implies that to achieve higher frame rates at 4K, a more powerful GPU would be necessary, as the i7-14700K is not the limiting factor in any scenario.

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

The measured FPS data provides a complete picture of the system's performance. At 1920x1080, the system is capable of very high frame rates. The Low preset yields an average FPS of 225, which is exceptionally smooth. Moving up to Medium results in 157.5 FPS, High produces 112.7 FPS, and Ultra drops to 105.8 FPS. These numbers indicate that at 1080p, the system is more than adequate for competitive or high-refresh-rate gaming, with even Ultra settings remaining above the 100 FPS mark.

At 2560x1440, the performance is still respectable but begins to show the GPU's limitations. The Low preset averages 143.2 FPS, which is excellent. Medium settings yield 99.4 FPS, and High and Ultra produce nearly identical results at 68.5 and 68.6 FPS, respectively. This convergence at the higher settings suggests that the GPU is becoming saturated with the workload. At 3840x2160, the system struggles to maintain high frame rates. Low settings produce 73.9 FPS, which is playable, but Medium drops to 53.3 FPS. High and Ultra settings are below the 40 FPS mark, at 39.9 and 37.4 FPS, respectively, making them less ideal for a smooth experience.

A: At High settings, the drop from 1080p (112.7 FPS) to 1440p (68.5 FPS) is a 39.2% decrease. The drop from 1440p to 4K (39.9 FPS) is a 41.8% decrease, showing a slightly larger penalty for the jump to 4K.

Settings Recommendations

For the best experience with this hardware, the data suggests prioritizing resolution over graphical fidelity. At 1920x1080, the Ultra preset is the best choice, delivering 105.8 FPS, which is both smooth and visually detailed. If a higher refresh rate monitor is in use, the Low preset at 225 FPS offers the maximum possible performance. At 2560x1440, the High and Ultra presets both deliver around 68.5 FPS, making them visually similar in performance. However, the Medium preset at 99.4 FPS provides a significantly smoother experience with a moderate visual compromise, making it the recommended setting for 1440p. At 3840x2160, all settings struggle to maintain a consistent 60 FPS, with the Low preset being the only one above it at 73.9 FPS. Therefore, for 4K gaming, the Low preset is the only viable option for a playable frame rate, though the reduction in visual quality may be significant.

How This Combo Ranks

The combination of the Intel Core i7-14700K and the AMD Radeon RX 5700 XT ranks 1255 out of 1769 tested combos in Pc Building Simulator. This places it in the lower third of all tested systems, which is a surprising result given the high-performance CPU. The ranking reflects the fact that the game is not CPU-intensive, and the GPU is a mid-range model from a previous generation. The CPU's excellent performance, which places it in the 96th percentile of all CPUs, does not boost the combo's rank because the game only uses a fraction of its capabilities. The GPU's performance, while adequate for 1080p, is a significant limiting factor at higher resolutions, preventing the combo from achieving higher frame rates and a better overall rank. The data shows that this combo is best suited for 1080p gaming, where it can deliver high frame rates, but it will struggle to provide a high-end experience at 1440p or 4K.
