Pc Building Simulator

The Intel Core i7-12700K and AMD Radeon RX 6800 XT combination in Pc Building Simulator presents a fascinating study in component scaling. The measured FPS data across resolutions and settings reveals a system that is overwhelmingly GPU-bound, with the CPU’s substantial thread count and high boost clocks providing a foundation that rarely becomes the limiting factor. This analysis interprets the measured rows to understand where the bottlenecks lie and what the experience implies for different display targets.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and consistent, pointing directly at the GPU as the primary constraint. At High settings, the average frame rate falls from 171 FPS at 1920x1080 to 106.9 FPS at 2560x1440, a reduction of roughly 37%. Pushing further to 3840x2160 yields just 57.5 FPS, which is about 66% lower than the 1080p figure. This steep, non-linear decline is a textbook indicator of pixel-throughput saturation on the graphics card.

The pattern holds across all settings. At Low settings, the system achieves 339 FPS at 1080p, 213.7 FPS at 1440p, and 114.7 FPS at 4K. The scaling factor between 1080p and 4K here is approximately 2.95x, meaning the GPU is delivering less than a third of the frame rate when pixel count quadruples. This suggests that even at the lowest visual complexity, the RX 6800 XT is the wall; the CPU is not stepping in to save performance because the workload is almost purely a fill-rate exercise.

The interesting nuance appears when comparing the 1080p to 1440p drop versus the 1440p to 4K drop. For Medium settings, going from 1080p (243.4 FPS) to 1440p (149.8 FPS) is a 38% decrease, while the jump from 1440p to 4K (78 FPS) is a 48% decrease. The larger relative loss at the highest resolution implies that memory bandwidth and raw shader throughput are being exhausted, a finding consistent with the GPU’s 512.0 GB/s bandwidth and 20.74 TFLOPS FP32 performance. The data indicates that 4K is only viable for high-refresh gaming if settings are lowered, while 1440p offers a more balanced trade-off.

GPU Role

The Radeon RX 6800 XT’s specifications are central to interpreting these results. With 16 GB of GDDR6 memory on a 256-bit bus, the card has ample capacity for Pc Building Simulator’s scene complexity, which rarely demands more than 8 GB even at 4K Ultra. The data shows that the Ultra preset at 3840x2160 yields 55.6 FPS, slightly below the High preset’s 57.5 FPS, indicating that the extra visual features in Ultra are not memory-bound but rather compute-bound. The card’s 4608 shading units and 128 ROPs are the likely culprits for the resolution scaling observed.

Clock speeds further explain the performance profile. The GPU’s game clock is 2015 MHz with a boost up to 2250 MHz, and the measured FPS at 1440p High (106.9 FPS) suggests the card is running near its boost envelope under sustained load. The memory clock of 2000 MHz (16 Gbps effective) translates to that 512.0 GB/s bandwidth, which becomes a critical factor at 4K. Comparing the 4K Low (114.7 FPS) to the 4K Medium (78 FPS) shows a 32% performance hit for raising settings, a larger penalty than the 1080p Low-to-Medium drop (339 to 243.4 FPS, a 28% decrease). This widening gap at higher resolutions is the signature of bandwidth and fill-rate pressure.

The GPU’s benchmark percentile (87th among all GPUs) and its nearest rivals — the Intel Arc A550M (0.5% faster), NVIDIA RTX A1000 (1.7% faster), and NVIDIA CMP 50HX (1.9% slower) — place it in a solid mid-to-high tier. But for this game, the practical takeaway is that the 6800 XT is the definitive limiter at 4K Ultra, where it cannot hold 60 FPS.

CPU Role

The Intel Core i7-12700K is a 12-core, 20-thread processor with a boost clock of 5.00 GHz, and its benchmark data shows it is more than capable of feeding the GPU. The multicore scores — Cinebench R23 at 29241 and Passmark multithread at 34404 — indicate strong parallel throughput, but Pc Building Simulator is not a heavily threaded title. The single-thread performance is more relevant, with a Geekbench single-core score of 2561 and a 3DMark single-thread score of 1043, both of which suggest the CPU can handle game logic and draw calls without bottlenecking.

The measured FPS at 1080p Low (339 FPS) is the clearest evidence of CPU headroom. At such a low resolution, the GPU is underutilized, yet the frame rate still reaches over 300 FPS, implying the CPU is not the constraint. If the 12700K were a weaker part, we would expect to see a plateau around 200-250 FPS at 1080p Low, but the data shows no such ceiling. The CPU’s 25 MB of shared L3 cache and dual-channel DDR4/DDR5 memory support further reduce latency, which helps maintain consistent frame pacing even when the GPU is saturated.

The CPU’s percentile rank (89th among all CPUs) and its nearest rivals — the AMD Ryzen 7 PRO 5845 (-0.3%), Intel Core i7-13700T (0.6%), and Intel Core i5-14500HX (-0.7%) — show it is a top-tier part, but its role here is secondary. In this game, the CPU is a silent partner; the data suggests that even a significantly weaker processor would deliver nearly identical FPS at 4K, where the GPU is the sole bottleneck.

Settings Recommendations

The measured rows provide a clear hierarchy for optimizing the experience. At 1080p, all settings produce playable frame rates, but the Medium preset (243.4 FPS) offers the best compromise between visual fidelity and speed, nearly doubling the Ultra preset’s 164.8 FPS while still looking substantially better than Low (339 FPS). For competitive or high-refresh play, Low is the obvious choice, but Medium provides a smoother visual experience without sacrificing the 240 Hz potential.

At 1440p, the High preset (106.9 FPS) is the sweet spot. It delivers over 100 FPS, which is ideal for high-refresh monitors, and the jump from Medium (149.8 FPS) to High only costs 29% performance while adding meaningful detail. Ultra (104.4 FPS) is marginally slower than High, making it redundant unless the player prioritizes the few extra effects. The data suggests that High at 1440p is the most balanced setting for this combo.

For 4K, the situation changes. Ultra (55.6 FPS) and High (57.5 FPS) are both below the 60 FPS threshold, meaning neither is ideal for smooth gameplay. Medium (78 FPS) is the recommended preset here, as it maintains a comfortable margin above 60 FPS while still offering more detail than Low (114.7 FPS). The Low preset at 4K is a viable fallback for players who prioritize frame rate over visuals, but Medium provides the best overall experience based on the measured data.

How This Combo Ranks

The combination ranks 581st out of 1769 tested combos in Pc Building Simulator, placing it in the 67th percentile of all configurations. This is a strong showing, but not elite, which is surprising given the individual component rankings. The CPU’s 89th percentile and GPU’s 87th percentile would suggest a higher combo rank, but the game’s simulation nature may not fully utilize the hardware’s potential.

The rank implies that there are 580 combos that perform better, likely featuring higher-end GPUs or more recent CPUs. However, the measured FPS data shows that this combo is more than sufficient for 1080p and 1440p gaming, with only 4K Ultra proving challenging. The rank also reflects that Pc Building Simulator is not a demanding title, so the gap between this combo and the top-ranked ones may be smaller than in other games. The data indicates that this pairing is a high-midrange solution, offering excellent performance for most users, with the caveat that 4K enthusiasts might seek a more powerful GPU.

FAQ

Measured FPS Breakdown

The measured FPS data is presented below, organized by resolution and settings preset, with average frame rates as recorded.

1920x1080 (1080p):

• Low: 339 FPS
• Medium: 243.4 FPS
• High: 171 FPS
• Ultra: 164.8 FPS

2560x1440 (1440p):

• Low: 213.7 FPS
• Medium: 149.8 FPS
• High: 106.9 FPS
• Ultra: 104.4 FPS

3840x2160 (4K):

• Low: 114.7 FPS
• Medium: 78 FPS
• High: 57.5 FPS
• Ultra: 55.6 FPS

These numbers show a consistent pattern: the gap between Low and Medium is significant at every resolution, while the difference between High and Ultra is negligible. At 1080p, the scale from Low to Ultra spans 174.2 FPS, but at 4K, that span narrows to 59.1 FPS, confirming that the GPU’s pixel throughput is the dominant factor. The data is measured, and no minimum or maximum frame rates were recorded, so the average values represent the central tendency of performance. For players seeking the highest frame rates, Low is the only option, but for a balanced experience, Medium at 4K or High at 1440p are the optimal choices based on the measured results.
