# Resolution Scaling

The measured FPS data for Pc Building Simulator reveals a pronounced GPU-bound curve as resolution increases. At 1920x1080 with Low settings, the combo delivers 283.5 FPS, which drops to 177.3 FPS at 2560x1440 and further to 95.5 FPS at 3840x2160. This represents a 66.3% reduction from 1080p to 4K at Low settings, a steep decline that indicates the rendering pipeline is heavily dependent on pixel throughput rather than CPU geometry or simulation logic.

The scaling pattern shifts with higher quality presets. At Ultra settings, the frame rate falls from 132.9 FPS at 1080p to 87.0 FPS at 1440p, then to 45.0 FPS at 4K. The 1080p-to-4K drop at Ultra is 66.1%, nearly identical to the Low-setting decline. This consistency across quality levels suggests that the limiting factor is raw fillrate and memory bandwidth, not shader complexity or texture filtering. The RX 6750 XT's 432.0 GB/s memory bandwidth and 166.4 GPixel/s pixel rate are the primary constraints at higher resolutions.

Notably, the gap between Low and Ultra settings narrows as resolution increases. At 1080p, the difference is 150.6 FPS (283.5 vs 132.9), but at 4K it shrinks to 50.5 FPS (95.5 vs 45.0). This compression indicates that at 4K, the GPU is so saturated that settings adjustments have diminishing returns. The 4K Ultra result of 45.0 FPS sits just below the 47.4 FPS recorded at High, suggesting that the Ultra preset's additional effects push the GPU past its sustainable throughput.

The data points to a system where the Intel Core i9-14900K is never the bottleneck. Even at 1080p Low, where the CPU would typically dominate in simulation-heavy games, the combo still achieves 283.5 FPS. The Core i9-14900K's Cinebench R23 multi-core score of 49872 and PassMark multithread score of 58674 provide ample headroom for the game's simulation logic. The GPU, with its 79th percentile ranking among all GPUs, becomes the limiting component well before 1440p.

FAQ

Q: What is the best resolution for this combo in Pc Building Simulator?

A: The data shows 2560x1440 as the sweet spot. At High settings, it delivers 91.3 FPS, which is 2.4x the 4K High result of 47.4 FPS while maintaining visual fidelity. The 1080p High result of 141.1 FPS is smoother but the visual upgrade to 1440p is substantial.

Q: How does the RX 6750 XT compare to its nearest rivals in terms of raw GPU performance?

A: The RX 6750 XT's average benchmark score of 35327 places it 0.2% ahead of the AMD Radeon RX 5600M (35264) and 0.3% behind the NVIDIA GeForce RTX 5070 Ti Mobile (35435). It trails the AMD Radeon 880M by 0.9% and the NVIDIA GeForce RTX 3080 by 1.3%.

Q: Is the Core i9-14900K overkill for this game?

A: The benchmark results suggest yes. The CPU's 97th percentile ranking among all CPUs and its PassMark single-thread score of 4697 indicate it can handle far more demanding simulation workloads. The game's FPS is consistently limited by the GPU, not the CPU, even at 1080p Low.

Q: What is the FPS difference between High and Ultra at each resolution?

A: At 1080p, High produces 141.1 FPS versus 132.9 FPS for Ultra, a difference of 8.2 FPS. At 1440p, the gap widens to 4.3 FPS (91.3 vs 87.0). At 4K, the difference is 2.4 FPS (47.4 vs 45.0). Ultra consistently costs a small FPS penalty while adding visual effects.

Q: How does the combo rank among all tested combinations in this game?

A: This combo ranks 843rd out of 1769 tested combinations, placing it in the upper half of the distribution. The rank reflects the GPU's mid-tier positioning relative to the CPU's high-end status.

Q: Does the 12 GB VRAM affect performance at 4K?

A: The 4K results do not show evidence of VRAM capacity bottlenecking. The 45.0 FPS at 4K Ultra is consistent with the GPU's pixel rate limitations rather than memory exhaustion. The 12 GB GDDR6 memory with 432.0 GB/s bandwidth is sufficient for this game's 4K textures.

How This Combo Ranks

The combo's rank of 843 out of 1769 tested combinations places it near the median of all tested systems in Pc Building Simulator. This positioning is notable because the CPU component is exceptional—the Intel Core i9-14900K holds a 97th percentile ranking among all CPUs and outperforms its nearest rival, the AMD EPYC 7413, by 0.3% in average benchmark score (79824 vs 80041). The GPU, however, sits at the 79th percentile among all GPUs, which drags the overall combo ranking down.

The rank distribution suggests that Pc Building Simulator rewards GPU throughput more heavily than CPU compute. Systems with lower-tier CPUs but faster GPUs likely occupy higher ranks. The Core i9-14900K's PassMark data compression score of 792694 and floating point math score of 152975 are far beyond what this simulation game requires, making the CPU a minor contributor to the final rank.

The GPU's nearest rivals provide context for why this combo doesn't rank higher. The RX 6750 XT's average score of 35327 is only 1.3% below the NVIDIA GeForce RTX 3080 (35787), yet the RTX 3080 systems likely rank higher due to better sustained performance in this game. The combo's rank of 843 indicates it outperforms 926 other tested combinations, placing it comfortably in the upper-mid tier.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce 283.5 FPS, Medium drops to 199.0 FPS, High yields 141.1 FPS, and Ultra settles at 132.9 FPS. The delta between Low and Medium is 84.5 FPS, while the gap between High and Ultra is only 8.2 FPS, indicating that the Ultra preset adds minimal performance cost over High at this resolution.

Moving to 2560x1440, the frame rates scale down proportionally. Low produces 177.3 FPS, Medium 123.6 FPS, High 91.3 FPS, and Ultra 87.0 FPS. The Low-to-Medium gap narrows to 53.7 FPS, and the High-to-Ultra gap shrinks to 4.3 FPS. The 1440p results show a 37.5% reduction from 1080p at Low settings, and a 34.5% reduction at Ultra settings, confirming that the GPU is handling the increased pixel count with predictable efficiency.

At 3840x2160, the performance curve flattens considerably. Low produces 95.5 FPS, Medium 68.0 FPS, High 47.4 FPS, and Ultra 45.0 FPS. The Low-to-Medium gap is 27.5 FPS, while the High-to-Ultra gap is just 2.4 FPS. The 4K Ultra result of 45.0 FPS is the only sub-60 FPS measurement in the entire dataset, highlighting the GPU's limitation at this resolution. The 4K High result of 47.4 FPS is only marginally better.

Across all resolutions, the scaling efficiency from 1080p to 1440p averages approximately 63% of the original frame rate, while 1080p to 4K averages approximately 33%. These ratios are consistent with a GPU-bound scenario where the RX 6750 XT's 2560 shading units and 64 ROPs are the primary determinants of performance.

GPU Role

The AMD Radeon RX 6750 XT plays a decisive role in this combo's performance in Pc Building Simulator. With a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz, the GPU's clock speeds are consistently high across the benchmark results. The 12 GB of GDDR6 memory running at 2250 MHz (18 Gbps effective) provides 432.0 GB/s of memory bandwidth, which is sufficient for this game's texture streaming at 4K.

The GPU's 79th percentile ranking among all GPUs, with an average benchmark score of 35327, places it in the upper-mid tier. Its nearest rival, the AMD Radeon RX 5600M, scores 35264, a 0.2% difference that is within measurement noise. The NVIDIA GeForce RTX 3080, which scores 35787, is only 1.3% faster on average, yet the RTX 3080's higher pixel rate and memory bandwidth likely contribute to better 4K performance in this game.

The GPU's RDNA 2.0 architecture with 40 ray tracing cores and support for DirectX 12 Ultimate (12_2) enables the Ultra preset's advanced effects, but the measured FPS data shows these features are not the primary bottleneck. The texture rate of 416.0 GTexel/s and pixel rate of 166.4 GPixel/s are the limiting factors at 4K, as evidenced by the 45.0 FPS at Ultra versus 95.5 FPS at Low—a 52.9% reduction that aligns with the increased pixel workload.

The GPU's 250 W TDP and dual-slot design indicate it operates within standard power envelopes for this class, and the PCIe 4.0 x16 interface provides adequate bandwidth for the 12 GB frame buffer. The 7 nm TSMC process with 17,200 million transistors on a 335 mm² die delivers the FP32 performance of 13.31 TFLOPS, which is the compute ceiling for this game's shader workloads. The data confirms the GPU, not the CPU, is the component that determines whether this combo achieves 60+ FPS at 4K—it does not—or whether it remains comfortably above 90 FPS at 1440p—it does.
