A: At 1920x1080 Ultra, the average is 129.1 FPS. Moving to 3840x2160 Ultra drops the average to 40.2 FPS. This represents a 68.8% reduction in frame rate, highlighting a strong resolution scaling penalty.

Q: Does the CPU's benchmark percentile suggest it will bottleneck the GPU in this game?

A: The CPU is in the 93rd percentile for all CPUs, indicating very high performance. Given its 12 cores and 24 threads, the data suggests it is unlikely to be the limiting factor in this simulation title.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture and features 12 GB of GDDR6 memory on a 192-bit bus, providing a memory bandwidth of 384.0 GB/s. The GPU's clocks are listed with a base of 2321 MHz, a game clock of 2424 MHz, and a boost clock of 2581 MHz. The memory operates at 2000 MHz with 16 Gbps effective speed. These specifications position the card in the 77th percentile for all GPUs, with an average benchmark score of 33721.

In Pc Building Simulator, the GPU's role is clearly tied to rendering the visual interface and any 3D elements. The benchmark results show a direct correlation between graphical settings and frame rate, which indicates that the GPU's compute resources are being exercised. At 1920x1080, the difference between Low and Ultra settings is substantial, going from 268.5 FPS to 129.1 FPS. This 139.4 FPS gap underscores the GPU's workload scaling with visual effects. At 4K resolution, the card's limits become more apparent; even at Low settings, the average frame rate is 90.3 FPS, which drops to 40.2 FPS at Ultra. The data indicates that while the RX 6700 XT is capable of high frame rates at lower resolutions, its 12 GB memory buffer and 384.0 GB/s bandwidth are tasked heavily at 4K with high settings, resulting in a sub-60 FPS experience.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases, which is typical for a GPU-bound scenario. At 1920x1080 with High settings, the average frame rate is 132.6 FPS. Moving to 2560x1440, the average drops to 86.8 FPS, a 34.5% decrease. At 3840x2160, the average falls to 43.4 FPS, which is a 67.3% decrease from the 1080p result. This scaling suggests that the graphics card is the primary limiting component at higher resolutions, as the number of pixels being processed increases significantly.

The pattern is consistent across all settings. With Low settings, the frame rate goes from 268.5 FPS at 1080p to 171.3 FPS at 1440p and 90.3 FPS at 4K. The relative drops are 36.2% and 66.4% from 1080p, respectively. This consistent scaling indicates that the CPU is not a bottleneck, as the frame rate drops proportionally with the pixel count. If the CPU were the limiting factor, the frame rate would remain relatively flat across resolutions. The data shows the opposite, confirming that the RX 6700 XT's rendering capabilities are what determine the performance ceiling in Pc Building Simulator.

Measured FPS Breakdown

The measured data provides a complete picture of performance across three resolutions and four settings levels. At 1920x1080, the RX 6700 XT delivers high frame rates across the board. With Low settings, the average is 268.5 FPS. Medium settings yield 190.7 FPS. High settings produce 132.6 FPS, and Ultra settings result in 129.1 FPS. The difference between High and Ultra at this resolution is minimal, only 3.5 FPS, suggesting that the Ultra preset adds little graphical overhead that impacts performance.

At 2560x1440, the frame rates remain strong but show a clear step down. Low settings average 171.3 FPS, which is still very high. Medium settings produce 119.7 FPS, while High settings average 86.8 FPS. Ultra settings drop to 81.3 FPS. The gap between High and Ultra narrows further here, with only a 5.5 FPS difference. This suggests that the GPU is starting to become more constrained, but still maintains playable frame rates at all settings.

At 3840x2160, the performance takes a significant hit. Low settings average 90.3 FPS, which is the only setting to break the 60 FPS threshold at this resolution. Medium settings drop to 61.3 FPS, which is just above the 60 FPS target. High settings average 43.4 FPS, and Ultra settings fall to 40.2 FPS. The scaling from Low to Ultra at 4K shows a 55.5% reduction in frame rate, indicating that the GPU's compute units and memory bandwidth are heavily taxed by the higher pixel count and visual effects.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. It features a 64 MB shared L3 cache and supports DDR5 memory with a dual-channel configuration, providing 83.2 GB/s of memory bandwidth. The CPU is in the 93rd percentile for all CPUs, with an average benchmark score of 50556. Its nearest rival, the Intel Core Ultra 5 235, scores 50598, a 0.1% difference.

In Pc Building Simulator, the CPU's role is to manage the simulation logic, which includes tracking system components, temperatures, and performance metrics. The benchmark data shows that the CPU is not a limiting factor in this configuration. The frame rates scale consistently with resolution and settings, which is indicative of a GPU-bound scenario. At 1080p with Low settings, the CPU is able to feed the GPU enough data to achieve 268.5 FPS, which is a very high frame rate that would stress most processors.

The multi-threaded performance of the 7900X is strong, as evidenced by its Cinebench R23 multicore score of 43695 and its Passmark multithread score of 51406. These scores suggest that the CPU has ample headroom for the simulation's background tasks. The single-threaded performance is also solid, with a 3DMark single-thread score of 1093, which is important for the game's main logic thread. Given the CPU's 93rd percentile ranking and the fact that frame rates drop significantly at higher resolutions, the data clearly indicates that the RX 6700 XT is the bottleneck in Pc Building Simulator, not the Ryzen 9 7900X.
