A: At 1080p Low settings, the system achieves 246.3 FPS, which is exceptionally high. The gap between Low and Ultra at 1080p is 81.6 FPS (from 246.3 to 164.7), suggesting the CPU can feed the GPU adequately even at high frame rates.

Settings Recommendations

The measured data reveals a clear hierarchy of performance across settings presets. At 1920x1080, the Ultra preset delivers 164.7 FPS, which is already far beyond what most displays can show. The Medium preset at 216.3 FPS and Low at 246.3 FPS offer diminishing returns in smoothness but significantly lower visual quality. For 1080p users, the Ultra preset is the clear recommendation because it provides the best visual experience while still maintaining frame rates far above any practical refresh rate limit.

Moving to 2560x1440, the story becomes more nuanced. The High preset at 106.8 FPS offers an excellent balance, with the Ultra preset at exactly 100 FPS being nearly identical in smoothness. The Medium preset reaches 152.9 FPS, but the visual quality difference between Medium and High is typically more noticeable in simulation games where readability of UI elements matters. The data suggests that High at 1440p is the sweet spot, providing a comfortable 100+ FPS experience with good visual fidelity.

At 3840x2160, the picture changes dramatically. The High preset drops to 54.7 FPS, which is just below the 60 FPS threshold for smooth gameplay. The Medium preset at 77.6 FPS is the most balanced option at 4K, offering a 42% improvement over High while still maintaining acceptable visual quality. The Ultra preset at 51.4 FPS is playable but noticeably less smooth, and Low at 113.3 FPS sacrifices too much visual quality to be worthwhile on a high-resolution display. For 4K users, Medium is the recommended starting point, with High as an option for those who prioritize visuals over frame rate smoothness.

How This Combo Ranks

The combo's rank of 706 out of 1769 tested combinations places it in the 60th percentile of all tested systems. This is a notable position because it means the pairing outperforms the majority of configurations while not being among the top-tier systems. The RX 6800 XT's 87th percentile GPU standing is the primary driver of this ranking, while the i5-9400's 50th percentile CPU standing is essentially average.

This disconnect between GPU and CPU percentile rankings is instructive. The data indicates that the GPU is doing the heavy lifting in Pc Building Simulator, and the CPU is adequate but not exceptional. The 0.2% performance difference between the i5-9400 and its nearest rival, the i3-10305, suggests that CPU choice within this performance tier has minimal impact on overall system capability. The 706th rank out of 1769 combos also suggests that the system is neither overkill nor underpowered for the game, but rather a balanced mid-to-upper-tier configuration.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. The Low preset achieves 246.3 FPS, Medium reaches 216.3 FPS, High produces 173.1 FPS, and Ultra maintains 164.7 FPS. The difference between Low and Ultra at this resolution is 81.6 FPS, or approximately 33% lower performance at maximum settings. This is a relatively modest penalty for maximum visual quality, indicating that the GPU has ample headroom at 1080p.

The 2560x1440 results show a more pronounced scaling curve. Low yields 207.8 FPS, Medium drops to 152.9 FPS, High reaches 106.8 FPS, and Ultra delivers exactly 100 FPS. The step from Low to Medium is 54.9 FPS, from Medium to High is 46.1 FPS, and from High to Ultra is just 6.8 FPS. This suggests that the High to Ultra transition is relatively inexpensive in Pc Building Simulator, while the Medium to High jump carries the most substantial performance cost.

At 3840x2160, the performance envelope tightens considerably. Low produces 113.3 FPS, Medium manages 77.6 FPS, High reaches 54.7 FPS, and Ultra drops to 51.4 FPS. The difference between High and Ultra at 4K is only 3.3 FPS, indicating that these two presets are nearly identical in performance requirements. The gap between Low and Ultra at 4K is 61.9 FPS, a much larger relative penalty than at lower resolutions.

GPU Role

The AMD Radeon RX 6800 XT is clearly the dominant component in this pairing. With 16 GB of GDDR6 memory on a 256-bit bus providing 512.0 GB/s of bandwidth, the GPU has substantial resources for simulation games that may load many textures and assets. The 4608 shading units, 288 TMUs, and 128 ROPs give it a pixel rate of 288.0 GPixel/s and a texture rate of 648.0 GTexel/s, which explains its ability to maintain high frame rates even at 4K.

The GPU's clock behavior is also relevant. With a base clock of 1825 MHz, a game clock of 2015 MHz, and a boost clock of 2250 MHz, the RX 6800 XT scales its performance dynamically based on workload. The 20.74 TFLOPS of FP32 performance is substantial for a simulation title that may not utilize ray tracing heavily, but the 72 RT cores provide future-proofing for games that do. The GPU's 87th percentile ranking versus all GPUs, with an average benchmark score of 49982, confirms that it is a high-end part performing well above the median.

CPU Role

The Intel Core i5-9400 presents an interesting contrast to the GPU. With 6 cores and 6 threads, base clock of 2.90 GHz, and boost clock of 4.10 GHz, this Coffee Lake processor is a solid mid-range part. Its 9 MB of shared L3 cache and 42.7 GB/s memory bandwidth are adequate for gaming workloads, but its 50th percentile ranking versus all CPUs suggests it is exactly average in the broader CPU landscape.

The CPU's benchmark results show a multicore score of 3346 in Cinebench R20 and 7969 in Cinebench R23, which are respectable but not exceptional numbers. The fact that this combo still achieves 246.3 FPS at 1080p Low indicates that Pc Building Simulator is not heavily CPU-bound, or that the i5-9400's single-core performance (1125 in Cinebench R23 single-core) is sufficient for the game's simulation logic. The 0.2% performance delta between this CPU and its closest rival, the i3-10305, highlights that CPU choice within this tier has minimal impact on gaming performance.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals important information about which component is limiting performance. At High settings, the system delivers 173.1 FPS at 1080p, 106.8 FPS at 1440p, and 54.7 FPS at 4K. This represents a 38% drop from 1080p to 1440p and a 49% drop from 1440p to 4K. The scaling is relatively consistent, suggesting that the GPU is the primary bottleneck as resolution increases.

At Ultra settings, the pattern is similar: 164.7 FPS at 1080p, 100 FPS at 1440p, and 51.4 FPS at 4K. The 4K to 1080p ratio is approximately 3.2x, which is close to the pixel count ratio of 4x, indicating that the GPU is scaling nearly linearly with resolution. This is a strong indicator that the system is GPU-limited at higher resolutions, while the CPU has sufficient headroom to avoid becoming the bottleneck.

The Low settings data tells a slightly different story. At 1080p Low, the system achieves 246.3 FPS, which drops to 207.8 FPS at 1440p and 113.3 FPS at 4K. The smaller drop from 1080p to 1440p (38.5 FPS) compared to the drop from 1440p to 4K (94.5 FPS) suggests that at lower settings, the CPU begins to play a more significant role at 1080p, and the GPU becomes fully utilized as resolution increases. This pattern confirms that the RX 6800 XT is the performance ceiling for this combination, and the i5-9400 is sufficient to keep the GPU fed in most scenarios.
