Pc Building Simulator

Resolution Scaling

The measured FPS data for Pc Building Simulator reveals a clear and predictable scaling pattern as resolution increases, with the AMD Radeon RX 6750 XT becoming progressively more of a limiting factor. At 1080p with Ultra settings, the combo delivers 135.1 FPS, which drops to 83.9 FPS at 1440p and further to 43.3 FPS at 4K. This represents a 68.0% reduction in frame rate from 1080p Ultra to 4K Ultra, indicating that the GPU is heavily stressed at higher resolutions.

The scaling behavior shifts noticeably when examining Low settings. At 1080p Low, the system produces 282.6 FPS, falling to 177.5 FPS at 1440p and 92.1 FPS at 4K. The percentage drop from 1080p to 1440p Low is 37.2%, while the drop from 1440p to 4K Low is 48.1%. This steeper decline at the highest resolution suggests that even at Low settings, the GPU's memory bandwidth of 432.0 GB/s and its 192-bit bus width become constraining factors when pushing 8.3 million pixels at 4K.

The gap between Low and Ultra settings widens dramatically as resolution decreases. At 4K, the difference between Low (92.1 FPS) and Ultra (43.3 FPS) is 48.8 FPS, representing a 52.9% performance penalty for maxing out settings. At 1080p, that same gap grows to 147.5 FPS, with Low at 282.6 FPS versus Ultra at 135.1 FPS — a 52.2% reduction. This pattern indicates that at lower resolutions, the CPU has more headroom to feed the GPU, but the GPU's compute capabilities (13.31 TFLOPS FP32) still cap absolute performance.

The data suggests that 1440p is the resolution sweet spot for this combination. At High settings, 1440p delivers 90.6 FPS, which is 64.1% of the 1080p High result (141.4 FPS) but still comfortably above 60 FPS. The 4K results, however, show that Ultra settings (43.3 FPS) and even High settings (46.7 FPS) fall below the 60 FPS threshold, making 4K gaming a compromise-filled experience unless settings are dropped to Low or Medium.

How This Combo Ranks

Within the benchmark database, this Intel Core i7-14700K and AMD Radeon RX 6750 XT combination ranks 874th out of 1,769 tested combos for Pc Building Simulator. This places it in the 50.6th percentile of all tested configurations, meaning roughly half of all recorded combos perform better and half perform worse in this specific game.

The CPU component itself performs far better than the combo ranking suggests. The Core i7-14700K achieves an average benchmark score of 70,074, placing it in the 96th percentile among all CPUs tested. Its nearest rival, the Intel Core i7-14700KF, scores 70,104 with a deltaPct of 0 — meaning the two are statistically identical in performance. The AMD Ryzen 9 9950X scores 70,420, which is 0.5% higher than the i7-14700K, while the AMD EPYC 9115 scores 69,887, a 0.3% deficit. The Intel Xeon Platinum 8270 trails by 1.4% with a score of 71,056.

The GPU, however, is a different story. The RX 6750 XT ranks in the 79th percentile among all GPUs with an average benchmark score of 35,327. Its nearest rivals include the AMD Radeon RX 5600M at 35,264 (0.2% higher), the NVIDIA GeForce RTX 5070 Ti Mobile at 35,435 (0.3% lower), and the AMD Radeon 880M at 35,646 (0.9% lower). The NVIDIA GeForce RTX 3080 scores 35,787, which is 1.3% higher than the RX 6750 XT.

The discrepancy between the CPU's top-tier ranking and the combo's mid-pack position in Pc Building Simulator suggests that the GPU is the primary bottleneck in this pairing. The game's simulation nature likely relies more on GPU throughput than on the CPU's 20 cores and 28 threads, which explains why a 96th-percentile CPU cannot boost the combo beyond the median.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, manufactured on a 7 nm process by TSMC. It contains 17,200 million transistors across a 335 mm² die, with 2,560 shading units, 160 texture mapping units, and 64 raster operation units. The GPU operates at a base clock of 2150 MHz and boosts to 2600 MHz, with a game clock of 2495 MHz that represents the typical sustained frequency during gameplay.

Memory configuration consists of 12 GB of GDDR6 on a 192-bit bus, running at 2250 MHz with 18 Gbps effective speed. This yields a memory bandwidth of 432.0 GB/s, which proves adequate for 1080p and 1440p gaming but becomes strained at 4K, particularly at higher settings. The pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s provide the raw throughput needed for the game's rendering demands.

The GPU's ray tracing capabilities include 40 RT cores, though Pc Building Simulator does not appear to heavily utilize this feature based on the measured results. The FP32 compute performance of 13.31 TFLOPS and FP16 performance of 26.62 TFLOPS (2:1 ratio) are solid mid-range figures, consistent with the GPU's 79th percentile ranking among all GPUs.

The 12 GB VRAM capacity proves sufficient across all tested configurations. Even at 4K Ultra settings, where the GPU delivers 43.3 FPS, there is no indication of VRAM exhaustion causing severe frame drops. The measured FPS data shows smooth scaling across settings levels, suggesting that the memory subsystem is not a limiting factor. The GPU's dual-slot design and 250 W TDP require a 600 W suggested PSU, and the 1x 6-pin plus 1x 8-pin power connectors deliver the necessary energy.

Settings Recommendations

Based on the measured FPS data, the optimal settings configuration depends heavily on the target resolution and desired frame rate. For 1080p gaming, Medium settings provide the best balance of visual quality and performance, delivering 198.4 FPS — a 39.5% improvement over High settings (141.4 FPS) while still maintaining substantial visual fidelity over Low settings (282.6 FPS). The jump from Medium to Ultra at 1080p costs 63.3 FPS (from 198.4 to 135.1), which is a 31.9% performance penalty for the final tier of visual enhancements.

At 1440p, High settings emerge as the clear recommendation. The 90.6 FPS result provides a comfortable margin above 60 FPS, while Medium settings offer 128.3 FPS and Ultra drops to 83.9 FPS. The difference between High and Ultra at 1440p is only 6.7 FPS, making Ultra a reasonable choice for users with high refresh rate monitors. However, the 37.7 FPS gap between High (90.6) and Medium (128.3) suggests that High is the sweet spot for preserving visual quality without sacrificing smoothness.

For 4K resolution, the data indicates that Medium settings (64 FPS) are the highest quality tier that maintains playable frame rates. High settings at 46.7 FPS and Ultra at 43.3 FPS both fall below the 60 FPS threshold, while Low settings at 92.1 FPS sacrifice too much visual quality. Medium at 4K represents a 38.3% improvement over High and a 47.8% improvement over Ultra, making it the only viable option for 4K gaming with this hardware.

Measured FPS Breakdown

At 1920x1080 resolution, the RX 6750 XT and i7-14700K combination delivers 282.6 FPS on Low settings, 198.4 FPS on Medium, 141.4 FPS on High, and 135.1 FPS on Ultra. The progression from Low to Medium incurs a 84.2 FPS penalty (29.8%), while the Medium to High step costs 57.0 FPS (28.7%). The High to Ultra transition is comparatively gentle at 6.3 FPS (4.5%), suggesting diminishing returns at the highest quality tier.

At 2560x1440, the measured results are 177.5 FPS for Low, 128.3 FPS for Medium, 90.6 FPS for High, and 83.9 FPS for Ultra. The Low to Medium drop is 49.2 FPS (27.7%), Medium to High is 37.7 FPS (29.4%), and High to Ultra is 6.7 FPS (7.4%). The similar percentage drops between Low-Medium and Medium-High indicate a consistent scaling curve, while the High to Ultra step remains minimal.

The 3840x2160 results show 92.1 FPS on Low, 64 FPS on Medium, 46.7 FPS on High, and 43.3 FPS on Ultra. The Low to Medium penalty is 28.1 FPS (30.5%), Medium to High is 17.3 FPS (27.0%), and High to Ultra is 3.4 FPS (7.3%). At 4K, the absolute frame rates are significantly lower across all settings, with even Low settings barely exceeding 90 FPS.

Comparing across resolutions at the same settings, the scaling is consistent. At Ultra, 1080p (135.1 FPS) to 1440p (83.9 FPS) represents a 37.9% reduction, and 1440p to 4K (43.3 FPS) is a 48.4% reduction. At Low, the reductions are 37.2% (282.6 to 177.5) and 48.1% (177.5 to 92.1). This consistent pattern across settings confirms that resolution scaling is the dominant factor in performance variation.

CPU Role

The Intel Core i7-14700K is a 20-core, 28-thread processor based on the Raptor Lake architecture, manufactured on Intel's 10 nm process. It operates with a base clock of 3.40 GHz and boosts to 5.60 GHz, with a TDP of 125 W. The CPU supports DDR4 and DDR5 memory across a dual-channel interface and includes 33 MB of shared L3 cache, along with 2 MB L2 cache per core and 80 KB L1 cache per core.

In benchmark tests, the i7-14700K demonstrates exceptional multi-threaded performance with a Cinebench R23 multi-core score of 44,534 and a single-core score of 6,287. Geekbench results show 18,896 multi-core and 2,932 single-core scores. Passmark tests reveal strong performance in integer math (182,876), floating-point math (134,222), and data compression (695,234). The CPU's 96th percentile ranking among all CPUs confirms its high-end status.

However, in Pc Building Simulator, the CPU's role appears secondary to the GPU. The measured FPS data shows no signs of CPU bottlenecking — at 1080p Low settings, the system achieves 282.6 FPS, which would require substantial CPU throughput to feed the GPU at such high frame rates. The 28 threads and 5.60 GHz boost clock provide ample single-thread and multi-thread performance for the simulation's logic and physics calculations.

The CPU's nearest rivals in overall benchmark scores include the i7-14700KF with a deltaPct of 0, indicating identical performance, and the AMD Ryzen 9 9950X at -0.5%, which is statistically negligible. The AMD EPYC 9115 trails by 0.3%, and the Xeon Platinum 8270 is 1.4% behind. These comparisons suggest that the i7-14700K is well-positioned among top-tier CPUs, yet the combo's 874th rank out of 1,769 in this game points to the GPU as the limiting factor in achieving higher frame rates.
