Pc Building Simulator

Pc Building Simulator is a simulation title where the hardware configuration dictates system-building mechanics, and the measured data for the Intel Core i7-13700K paired with the AMD Radeon RX 6750 XT reveals a combo that is heavily GPU-limited at higher resolutions but becomes increasingly CPU-bound at 1080p. The benchmark results show a clear hierarchy where the graphics card's performance ceiling is reached before the processor's substantial 16-core, 24-thread capability is fully utilized, making the choice of resolution and settings the primary determinant of frame rates.

Resolution Scaling

The frame rate scaling from 1080p to 4K demonstrates a classic GPU-bound scenario, with the most significant drops occurring as the pixel count increases. At Low settings, the average FPS falls from 282.1 at 1920x1080 to 178.4 at 2560x1440, a reduction of 103.7 frames, and then further to 90.9 at 3840x2160, representing a 67.5% decrease from the 1080p figure. This steep decline is a strong indicator that the Radeon RX 6750 XT is the limiting component, as the workload per frame scales directly with resolution.

The pattern persists across all settings presets, though the relative drop from 1440p to 4K is more pronounced at lower quality levels. For instance, at High settings, the transition from 2560x1440 (87.1 FPS) to 3840x2160 (45.9 FPS) cuts performance nearly in half, while at Ultra, the drop from 86.7 to 43.3 FPS shows a similar halving. This consistent ~50% reduction when moving from 1440p to 4K indicates that the GPU's rendering throughput, which is tied to its 432.0 GB/s memory bandwidth and 13.31 TFLOPS FP32 compute, is being saturated.

At 1080p, the scaling behavior changes character. The jump from 143.7 FPS at High to 282.1 FPS at Low shows that reducing graphical load can nearly double performance, suggesting that at this resolution the GPU still has headroom, but the CPU's single-thread performance (3dmark_single_thread score of 1136) begins to matter more at the lower settings. The data shows that the combo is most balanced at 1440p Medium, where the 127.3 FPS average suggests neither component is severely bottlenecked, but the overall trend firmly establishes the RX 6750 XT as the performance limiter in this pairing.

GPU Role

The AMD Radeon RX 6750 XT's specifications directly explain its behavior in this game. With 12 GB of GDDR6 memory on a 192-bit bus delivering 432.0 GB/s bandwidth, the card has ample memory capacity for Pc Building Simulator's scene complexity, but the bandwidth becomes a constraint at 4K resolutions. The benchmark results show that the GPU's compute capabilities, rated at 13.31 TFLOPS FP32, are the primary bottleneck when moving from 1440p to 4K, as evidenced by the consistent performance halving regardless of settings.

The card's clock speeds, with a base of 2150 MHz and boost up to 2600 MHz, allow it to maintain strong performance at 1440p, where it achieves 178.4 FPS at Low settings. However, the 40 ray tracing cores and 64 ROPs do not provide enough throughput to sustain high frame rates at 4K Ultra, where the average drops to 43.3 FPS. The GPU's percentile rank of 79 versus all GPUs, and its average benchmark score of 35327, place it in the upper mid-range, which aligns with its measured performance in this simulation title.

Comparing to its nearest rivals, the RX 6750 XT's average benchmark score of 35327 is only 0.2% ahead of the AMD Radeon RX 5600M (35264) and 0.3% behind the NVIDIA GeForce RTX 5070 Ti Mobile (35435). This tight grouping suggests that the GPU's performance in Pc Building Simulator is typical for its class, though the game's engine appears to favor raw fill rate over ray tracing capabilities, explaining why the 4K Ultra results (43.3 FPS) are not playable for a smooth experience.

How This Combo Ranks

The combo of the Intel Core i7-13700K and AMD Radeon RX 6750 XT ranks 854 out of 1769 tested combinations in Pc Building Simulator, placing it in the 48th percentile among all combos. This mid-pack ranking is somewhat surprising given the individual strengths of both components, but it reflects the game's modest hardware demands where even lower-end CPUs can keep up with the GPU at most settings.

The CPU's percentile rank of 93 versus all CPUs indicates it is a top-tier processor, but in this game, the bottleneck is clearly the GPU. The i7-13700K's nearest rival, the Intel Core i7-13700KF, has an average score of 47334, which is just 0.1% higher, showing that the CPU is not the limiting factor. Meanwhile, the GPU's rank of 79 places it well below the CPU's standing, confirming that the combo's overall rank is dragged down by the graphics card's mid-range positioning.

In practical terms, this 854th ranking out of 1769 means the combo sits almost exactly in the middle of all tested configurations. This is a fair representation of the hardware balance: the CPU has significant headroom that is never fully exploited, while the GPU consistently hits its performance ceiling. For users who prioritize high refresh rate gaming at 1080p, this combo overdelivers, but for 4K enthusiasts, the ranking reflects the GPU's inability to maintain high frame rates at that resolution.

Settings Recommendations

For 1920x1080, the Ultra preset at 134.4 FPS is entirely playable and provides the best visual experience without sacrificing smoothness, as the frame rate remains well above 100 FPS. Users with high refresh rate monitors (144Hz or above) could consider High settings at 143.7 FPS, which is nearly identical in performance but may offer slightly better visual fidelity depending on the game's implementation.

At 2560x1440, the Medium preset at 127.3 FPS is the recommended choice, as it maintains a high frame rate while still providing a significant visual upgrade over Low (178.4 FPS). The High preset at 87.1 FPS is acceptable for 60Hz displays, but the drop to 86.7 FPS at Ultra makes the extra graphical load not worthwhile for the marginal difference.

For 3840x2160, the data suggests that High settings at 45.9 FPS are borderline playable for slower simulation gameplay, but Low settings at 90.9 FPS are the only option that ensures a consistently smooth experience. The Medium preset at 68.6 FPS represents a compromise, though users should be aware that the GPU's limitations at this resolution make Ultra (43.3 FPS) a poor choice for any serious gaming session.

CPU Role

The Intel Core i7-13700K provides substantial computational headroom in this pairing, with 16 cores and 24 threads operating at a base clock of 3.40 GHz and boost up to 5.40 GHz. The CPU's benchmark results, including a Cinebench R23 multicore score of 39000 and a single-core score of 5505, place it in the 93rd percentile among all CPUs, yet the game's frame rates do not reflect this strength beyond 1080p.

At 1920x1080 with Low settings, the 282.1 FPS average suggests the CPU can feed the GPU adequately, but the 3dmark_16_threads score of 10717 and 3dmark single-thread score of 1136 indicate that the game likely relies on a few threads rather than the full 24-thread capacity. The CPU's nearest rival, the Intel Core i7-13700KF, scores 47334 on average, just 0.1% higher, confirming that the CPU is performing as expected in this title.

The processor's 30 MB of shared L3 cache and support for both DDR4 and DDR5 memory, along with its 125 W TDP, make it a potent component, but in Pc Building Simulator, the GPU bottleneck means the CPU's power is largely underutilized. The data shows that at 4K, the CPU's performance is irrelevant, as the frame rates are determined almost entirely by the GPU, while at 1080p Low, the CPU's strong single-thread performance helps maintain the high 282.1 FPS figure.

Measured FPS Breakdown

At 1920x1080, the combo produces 282.1 FPS at Low, 200.7 FPS at Medium, 143.7 FPS at High, and 134.4 FPS at Ultra. These results show a clear progression where each settings tier reduces performance by roughly 30-40%, with the largest gap between Low and Medium (81.4 FPS difference) and a smaller gap between High and Ultra (9.3 FPS difference).

Moving to 2560x1440, the frame rates drop to 178.4 FPS at Low, 127.3 FPS at Medium, 87.1 FPS at High, and 86.7 FPS at Ultra. The relative performance decrease from 1080p to 1440p is consistent across settings, with the Low preset losing 36.8% of its performance and the Ultra preset losing 35.5%, indicating a uniform GPU scaling pattern.

At 3840x2160, the averages are 90.9 FPS at Low, 68.6 FPS at Medium, 45.9 FPS at High, and 43.3 FPS at Ultra. The drop from 1440p to 4K is more severe, with the High preset falling from 87.1 to 45.9 FPS (a 47.3% reduction) and the Ultra preset falling from 86.7 to 43.3 FPS (a 50.1% reduction). This confirms that the GPU's memory bandwidth and compute resources are exhausted by the 4K resolution, making the RX 6750 XT the definitive bottleneck in this configuration.
