Pc Building Simulator

Pc Building Simulator places unusual demands on a system, and the measured results for the Intel Core i5-12400 paired with the AMD Radeon RX 7900 XTX reveal a configuration that is heavily balanced toward GPU throughput, with the CPU providing ample headroom. The data indicates a simulation title where raw frame rates scale dramatically with both resolution and quality preset, offering a clear picture of where the performance ceiling lies for this specific hardware combination.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent across all settings, confirming that the AMD Radeon RX 7900 XTX is the primary limiting component at higher resolutions. At Low settings, the average FPS falls from 350.6 at 1920x1080 to 139.7 at 3840x2160, a reduction of 60.2%. This scaling pattern is typical for a GPU-bound scenario, where the pixel throughput demand at 4K overwhelms the shading and memory bandwidth capabilities of the graphics card.

The gap between 1440p and 4K is particularly telling. At Medium settings, the system produces 191.0 FPS at 2560x1440 but only 101.4 FPS at 3840x2160, a drop of 46.9%. Similarly, at High settings, the 134.6 FPS at 1440p falls to 73.0 FPS at 4K, a 45.8% decrease. This indicates that while the RX 7900 XTX with its 24 GB of GDDR6 memory and 960.0 GB/s bandwidth handles 1440p with relative ease, the jump to 4K forces the GPU to work near its limits, resulting in a performance penalty that far exceeds the linear increase in pixel count.

Interestingly, the scaling from 1080p to 1440p is less severe. At Ultra settings, the average FPS goes from 202.0 at 1080p to 127.0 at 1440p, a 37.1% drop. This suggests that at 1080p, the Intel Core i5-12400, with its 6 cores and 12 threads, is beginning to provide enough instruction throughput to keep the GPU fed, but the GPU still dominates the frame time. The data points to a system where the CPU’s Cinebench R23 multi-core score of 15935 is more than sufficient for this simulation, making the GPU the definitive bottleneck as resolution climbs.

GPU Role

The AMD Radeon RX 7900 XTX plays the central role in these results, and its specifications directly explain the observed frame rates. The GPU’s 24 GB of GDDR6 memory operating at 20 Gbps effective and a 384-bit bus width yields a bandwidth of 960.0 GB/s, which is critical for a simulation that manages numerous assets and textures. The 6144 shading units and 192 ROPs, paired with a boost clock of 2498 MHz, provide the raw compute power necessary for the high frame rates seen at lower resolutions.

Benchmark results for the GPU show a Passmark G3D score of 31238 and an average benchmark score of 44019. The GPU’s percentile vs all GPUs is 85, indicating strong performance. However, its nearest rivals in the data, such as the NVIDIA GeForce RTX 4070 Ti with a deltaPct of -2, show that the RX 7900 XTX is not in a class of its own, but rather a high-end part that loses efficiency as the resolution climbs. The fact that the GPU’s frame rate at 4K Ultra is 65.5 FPS, compared to 350.6 FPS at 1080p Low, underscores how the GPU’s memory bandwidth and pixel fill rate are taxed by the higher resolution.

The GPU’s 96 RT cores and DirectX 12 Ultimate support are present in the hardware, but the measured FPS data does not isolate ray tracing effects. The results suggest that for Pc Building Simulator, which is not a graphically intensive first-person shooter, the GPU’s raw rasterization performance is the key driver. The passmark_directx_12 score of 131 and passmark_directx_11 score of 356 are low, but these are synthetic tests that may not reflect the game’s specific workload. The average FPS of 210.5 at 1080p High indicates that the GPU is not being fully utilized at this resolution, leaving headroom for higher refresh rate displays.

Settings Recommendations

The measured FPS rows provide clear guidance on the optimal settings for this hardware combination. At 4K, the Ultra preset yields an average of 65.5 FPS, which is playable but close to the lower bound for smooth gameplay. The High preset at 4K offers 73.0 FPS, a marginal improvement, while the Medium preset jumps to 101.4 FPS. For a 60 Hz display, the Medium preset at 4K is the best choice, as it provides a 38.9% improvement over Ultra while maintaining visual fidelity that is still above the Low preset’s 139.7 FPS.

At 1440p, the High preset delivers 134.6 FPS, which is sufficient for high refresh rate monitors. The Ultra preset at 127.0 FPS is also viable, but the difference between High and Ultra is only 5.6%, suggesting that the visual gains from Ultra are not worth the performance cost. The Medium preset at 191.0 FPS is the sweet spot for competitive play or for users who prefer maximum smoothness, as it offers a 42.0% increase over High while still providing a solid visual experience. The data shows that the Low preset at 1440p (266.3 FPS) is overkill for most displays and should be avoided unless chasing extreme frame rates.

At 1080p, all presets are above 200 FPS, with the Low preset reaching 350.6 FPS. The Medium preset at 303.0 FPS and High at 210.5 FPS are both excellent. For the best experience, the High preset is recommended, as it balances the 202.0 FPS of Ultra with a slightly higher frame rate, and the visual difference between High and Ultra is often negligible in this genre. The data indicates that the system is CPU-bound at 1080p Low, as the 350.6 FPS figure is likely near the limit of what the Intel Core i5-12400 can sustain.

Measured FPS Breakdown

The complete set of measured average FPS values shows a consistent pattern of performance degradation as resolution and quality increase. At 1920x1080, the system achieves 350.6 FPS on Low, 303.0 FPS on Medium, 210.5 FPS on High, and 202.0 FPS on Ultra. The drop from Medium to High is 30.5%, which is significant, while the drop from High to Ultra is only 4.0%, suggesting diminishing returns at the highest quality setting.

At 2560x1440, the results are 266.3 FPS on Low, 191.0 FPS on Medium, 134.6 FPS on High, and 127.0 FPS on Ultra. The step from Medium to High is a 29.5% reduction, and from High to Ultra is 5.6%. The scaling here mirrors the 1080p pattern, with the largest performance hit occurring between Medium and High.

At 3840x2160, the system produces 139.7 FPS on Low, 101.4 FPS on Medium, 73.0 FPS on High, and 65.5 FPS on Ultra. The drop from Low to Medium is 27.4%, from Medium to High is 28.0%, and from High to Ultra is 10.3%. This indicates that at 4K, the GPU is so heavily loaded that even the transition from High to Ultra has a measurable impact, unlike at lower resolutions where the CPU can compensate.

The data also shows that the difference between 1080p and 1440p at the same settings is consistent. For example, at Ultra, the 1080p score of 202.0 FPS drops to 127.0 FPS at 1440p, a 37.1% reduction. At High, the 210.5 FPS drops to 134.6 FPS, a 36.1% reduction. This uniformity suggests that the rendering pipeline scales linearly with pixel count until the GPU’s limits are reached at 4K.
