Pc Building Simulator

The Intel Core i5-12600KF paired with the AMD Radeon RX 6800 XT delivers a performance profile in PC Building Simulator that is heavily dictated by resolution and graphics preset. The benchmark data reveals a system capable of high refresh rate gaming at 1440p, but which becomes firmly GPU-limited at 4K, where even the most demanding settings struggle to maintain smooth frame rates.

Resolution Scaling

The frame rate drop from 1080p to 4K is severe, indicating that the Radeon RX 6800 XT is the primary limiting component at higher resolutions. At Low settings, the transition from 1920x1080 (337.9 FPS) to 3840x2160 (110.3 FPS) represents a 67.4% reduction in average FPS. This massive scaling factor is typical of a simulation title that becomes increasingly pixel-bound as the resolution increases, placing the full brunt of the workload on the GPU's rendering pipeline.

The scaling pattern is consistent across all presets, but the relative drop is most pronounced at Ultra settings. Moving from 1080p Ultra (159.9 FPS) to 4K Ultra (53.8 FPS) yields a 66.4% decrease, confirming that the GPU's fill rate and memory bandwidth are exhausted long before the CPU becomes a factor. The data shows that while the RX 6800 XT can handle 1440p with ease, 4K gaming demands a more powerful graphics solution or a reduction in visual fidelity.

Interestingly, the gap between 1440p and 4K is larger than the gap between 1080p and 1440p. At High settings, the drop from 1080p (168.6 FPS) to 1440p (108.2 FPS) is 35.8%, while the drop from 1440p to 4K (55.2 FPS) is 49.0%. This suggests that the GPU's 256-bit memory bus and 512.0 GB/s bandwidth are adequate for 1440p, but the 4K resolution's pixel count overwhelms the render output units, causing a disproportionate performance penalty.

CPU Role

The Intel Core i5-12600KF is a 10-core, 16-thread processor based on the Alder Lake architecture, with a base clock of 3.70 GHz and a boost clock of 4.90 GHz. In PC Building Simulator, a game primarily driven by logic and component simulation, the CPU's 20 MB of shared L3 cache and high single-thread performance are more relevant than raw multi-core throughput.

Benchmark results show the CPU achieving a Cinebench R23 single-core score of 3309 and a multi-core score of 23444. This strong single-core performance is critical for the game's simulation loop, which likely relies on a single main thread for physics and component interactions. The PassMark single-thread score of 3925 further reinforces this, as the game's frame pacing at lower resolutions is likely dependent on this metric.

The CPU's 3DMark scores tell a story of diminishing returns with thread count: 7956 for 16 threads, 6128 for 8 threads, and 3806 for 4 threads. This indicates that while the processor scales well, the game itself may not utilize all 16 threads effectively. The data suggests that the i5-12600KF provides ample headroom at 1080p, where the CPU is not the bottleneck, but its performance is still sufficient to keep pace with the GPU's output at 1440p and above.

GPU Role

The AMD Radeon RX 6800 XT is the clear performance driver in this configuration. With 16 GB of GDDR6 memory on a 256-bit bus and a bandwidth of 512.0 GB/s, the card has the resources to handle large texture loads and high-resolution rendering. Its boost clock of 2250 MHz and 4608 shading units deliver substantial raw compute power, reflected in a PassMark G3D score of 24980.

The GPU's 72 ray accelerators and RDNA 2.0 architecture provide modern feature support, but PC Building Simulator is not a graphically intensive title in terms of ray tracing. Instead, the card's fill rate (288.0 GPixel/s) and texture rate (648.0 GTexel/s) are the key specs that determine performance. At 4K Ultra, the card drops to 53.8 FPS, indicating that it is hitting its pixel throughput limits when pushing 8.3 million pixels per frame.

The GPU's benchmark scores position it in the 87th percentile of all GPUs, with a nearest rival being the NVIDIA GeForce RTX 4070 Ti SUPER, which scores 2.6% higher. This competitive positioning explains why the card handles 1440p High at 108.2 FPS, a smooth experience for most monitors, but falls short of the 60 FPS target at 4K Ultra. The data shows that the RX 6800 XT is a high-end card that excels at 1440p, but 4K gaming requires turning down settings to Medium (82.1 FPS) or Low (110.3 FPS) to achieve playable frame rates.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across all resolution and settings combinations. At 1920x1080, the system delivers exceptional frame rates across the board: 337.9 FPS at Low, 239.2 FPS at Medium, 168.6 FPS at High, and 159.9 FPS at Ultra. These numbers indicate that the combination is severely CPU or game-logic limited at 1080p, as the GPU has significant headroom that is not being utilized.

Moving to 2560x1440, the frame rates remain highly playable: 216.6 FPS at Low, 150.2 FPS at Medium, 108.2 FPS at High, and 101.5 FPS at Ultra. This resolution represents the sweet spot for this combo, as even Ultra settings maintain a frame rate above 100 FPS, which is ideal for high refresh rate displays. The difference between High (108.2) and Ultra (101.5) at 1440p is only 6.7 FPS, suggesting that the Ultra preset's additional effects are not overly taxing on the GPU.

At 3840x2160, the performance drops significantly: 110.3 FPS at Low, 82.1 FPS at Medium, 55.2 FPS at High, and 53.8 FPS at Ultra. The data shows that the gap between High and Ultra at 4K is minimal (1.4 FPS), indicating that the GPU is fully saturated and the visual differences between these presets are negligible in terms of cost. For a 60 Hz 4K display, only Low and Medium settings provide sufficient headroom, while High and Ultra will result in occasional stutters.

Settings Recommendations

The optimal experience for this combination depends heavily on the target resolution and refresh rate. For 1080p users, the Ultra preset at 159.9 FPS is the clear choice, as it delivers maximum visual quality without sacrificing smoothness. Even the most demanding settings cannot push the frame rate below 150 FPS at this resolution, making the Ultra preset a no-brainer for any 1080p display.

For 1440p, the High preset (108.2 FPS) is the recommended balance. It offers a 6.7 FPS advantage over Ultra (101.5 FPS) while maintaining near-identical visual quality in a simulation title where the extra effects are marginal. If a player has a 144 Hz monitor, the Medium preset at 150.2 FPS provides a more consistent high-refresh experience, but the visual downgrade may not be worth the 42 FPS gain for most users.

At 4K, the Medium preset (82.1 FPS) is the only viable option for smooth gameplay on a 60 Hz display. Low (110.3 FPS) provides a significant frame rate buffer but sacrifices too much visual fidelity for a game that is not graphically demanding. High and Ultra should be avoided at 4K, as they dip below 60 FPS, and the data shows that the difference between High (55.2) and Ultra (53.8) is negligible, making High the better choice if a player insists on higher quality despite the frame rate cost.
