Pc Building Simulator

Pc Building Simulator is a simulation title that responds heavily to both CPU and GPU, and the Intel Core i5-12400 + NVIDIA GeForce RTX 4070 Ti combination delivers a wide performance envelope. The data shows a system that can handle this game at nearly any resolution, but the frame rate scaling reveals where the bottleneck shifts. This analysis uses the measured FPS rows to interpret how this pairing behaves across 1080p, 1440p, and 4K, with a focus on practical settings and component roles.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent, indicating a GPU-bound workload at higher resolutions. At Ultra settings, the average frame rate falls from 206.2 FPS at 1920x1080 to 127.3 FPS at 2560x1440, then down to 67.7 FPS at 3840x2160. That is a 39% reduction from 1080p to 1440p, and another 47% reduction from 1440p to 4K. The pattern is similar across presets, but the absolute numbers tell a clearer story about the limiting component.

At Low settings, the scaling is more dramatic. The system produces 349.4 FPS at 1080p, 272.7 FPS at 1440p, and 142 FPS at 4K. The 4K figure is less than half of the 1080p result, which suggests that even at Low settings, the GPU’s pixel throughput becomes the constraint. The RTX 4070 Ti with 504.2 GB/s of memory bandwidth and 208.8 GPixel/s pixel rate is doing substantial work, but the resolution increase still demands more.

Medium settings show a similar curve: 307.3 FPS at 1080p, 190.3 FPS at 1440p, and 102.6 FPS at 4K. The gap between 1080p and 1440p is 38%, which is larger than the gap between 1440p and 4K (46%). This non-linear behavior indicates that at 1080p, the CPU may be holding back the GPU, especially on Low and Medium presets where the frame rates exceed 300 FPS. The Core i5-12400 has a boost clock of 4.40 GHz and 6 cores, which is capable, but at 349.4 FPS, the CPU’s single-thread performance becomes a factor.

At 4K, the game is clearly GPU-bound. The difference between High (72 FPS) and Ultra (67.7 FPS) is small, only 6%, while the jump from Low (142 FPS) to Medium (102.6 FPS) is 28%. This suggests that at 4K, the GPU’s compute and memory bandwidth are the primary drivers, and the CPU has enough headroom with its 12 threads. The data indicates that for players targeting 4K, the RTX 4070 Ti is the decisive component, while at 1080p, the i5-12400’s limits may surface only at extreme frame rates.

Settings Recommendations

Based on the measured rows, the best experience at 4K is the High preset. It delivers 72 FPS, which is above the 60 FPS threshold for smooth gameplay, while Ultra drops to 67.7 FPS for a negligible visual gain. The 4.3 FPS difference between High and Ultra is not worth the potential stability risk, especially since the game is a simulation where consistent frame pacing matters. At 4K, Medium is also viable at 102.6 FPS if you want higher frame rates, but High offers the best balance of visual fidelity and performance.

At 1440p, the Ultra preset delivers 127.3 FPS, which is excellent for high-refresh-rate monitors. The data shows that High (134.6 FPS) and Ultra (127.3 FPS) are within 6% of each other, so the choice depends on whether you prefer maximum settings or extra headroom. The Medium preset at 190.3 FPS is overkill for most displays, but it demonstrates that the system has significant reserve at this resolution. For competitive play or very high refresh rates, Medium is the sweet spot, but for visual quality, Ultra is recommended.

At 1080p, the situation is different. The Ultra preset runs at 206.2 FPS, which is still very high, but the Low preset hits 349.4 FPS. The data suggests that at 1080p, the CPU is the limiting factor beyond a certain point, as the GPU can clearly push more frames. For most users, Ultra or High at 1080p is the right call, as the difference between 206.2 and 349.4 FPS is likely imperceptible on standard 144Hz or 165Hz monitors. The High preset at 217.5 FPS is a solid choice, as it provides a noticeable visual upgrade over Medium (307.3 FPS) without the frame rate penalty being meaningful.

GPU Role

The NVIDIA GeForce RTX 4070 Ti is the dominant component in this pairing, particularly at higher resolutions. Its 12 GB of GDDR6X memory with a 192-bit bus and 504.2 GB/s bandwidth is well-suited for Pc Building Simulator, which likely loads many textures and models. The GPU’s boost clock of 2610 MHz and base clock of 2310 MHz, combined with 7680 shading units and 80 ROPs, explain why the card maintains high frame rates even at 4K. The pixel rate of 208.8 GPixel/s and texture rate of 626.4 GTexel/s are directly relevant to the resolution scaling seen in the data.

The GPU’s average benchmark score of 44900 places it in the 85th percentile among all GPUs, and its nearest rivals include the NVIDIA GeForce RTX 5090 Mobile (deltaPct -0.6) and the Intel Arc A730M (deltaPct -1.5). This means the RTX 4070 Ti is competitive with mobile top-tier parts, but it outpaces the AMD Radeon Pro 580 by 1.6% and is only 1.5% behind the Intel Arc A730M. In this game, the GPU’s strengths are clear: the 4K Ultra result of 67.7 FPS is respectable, but the 4K Low result of 142 FPS shows that the card has substantial headroom when settings are lowered.

The GPU’s 285 W TDP and suggested 600 W PSU are consistent with its performance class, but the data does not show any thermal throttling effects. The memory clock of 1313 MHz, effective 21 Gbps, is typical for GDDR6X, and the 35,800 million transistors on a 294 mm² die indicate a dense design that handles compute-heavy tasks well. For this game, the RTX 4070 Ti is the primary reason why 1440p Ultra is playable at 127.3 FPS, and why 4K High is viable at 72 FPS.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all presets. Low settings produce 349.4 FPS, Medium 307.3 FPS, High 217.5 FPS, and Ultra 206.2 FPS. The gap between Low and Medium is 42.1 FPS (12%), but the gap between Medium and High is 89.8 FPS (29%), indicating that High settings introduce significant GPU load. The difference between High and Ultra is only 11.3 FPS (5%), suggesting that Ultra is not much more demanding than High at this resolution.

At 2560x1440, the frame rates are lower but still very high. Low settings hit 272.7 FPS, Medium 190.3 FPS, High 134.6 FPS, and Ultra 127.3 FPS. The scaling from 1080p to 1440p is consistent: Low drops by 22%, Medium by 38%, High by 38%, and Ultra by 38%. This uniformity indicates that the GPU is becoming the bottleneck at 1440p, as the CPU has less impact on the frame rate.

At 3840x2160, the performance drops significantly. Low settings yield 142 FPS, Medium 102.6 FPS, High 72 FPS, and Ultra 67.7 FPS. The scaling from 1440p to 4K is steeper for lower presets: Low drops by 48%, Medium by 46%, High by 47%, and Ultra by 47%. This tells a clear story: at 4K, the GPU is fully utilized, and the CPU’s role is minimized. The 4K Ultra result of 67.7 FPS is the lowest in the dataset, but it is still playable, while 4K Low at 142 FPS shows that the GPU can handle the resolution if settings are reduced.

How This Combo Ranks

The Intel Core i5-12400 + NVIDIA GeForce RTX 4070 Ti combination ranks 229th out of 1769 tested combos in Pc Building Simulator. This places it in the top 13% of all configurations, which is a strong showing for a mid-range CPU paired with a high-end GPU. The ranking reflects the system’s ability to maintain high frame rates across all resolutions, but it also indicates that there are many faster combos, likely with higher-end CPUs or more powerful GPUs.

The CPU’s average benchmark score of 19850 puts it in the 77th percentile among all CPUs, and its nearest rivals are the Intel Core i7-9700 (deltaPct 0.1), Intel Core i7-8700 (deltaPct -0.2), AMD Ryzen Threadripper PRO 5995WX (deltaPct -0.4), and Intel Core i5-11600K (deltaPct 0.4). These small deltas mean the i5-12400 is essentially on par with those parts in synthetic benchmarks, but in this game, the GPU does most of the heavy lifting. The combo’s rank of 229 is more indicative of the GPU’s strength than the CPU’s, as the RTX 4070 Ti’s 85th percentile GPU ranking (avg score 44900) is higher than the CPU’s 77th percentile.

The data shows that this combo is well-balanced for Pc Building Simulator, as the rank suggests it outperforms the majority of tested systems. However, the gap between the CPU and GPU percentiles implies that a weaker CPU could still achieve a similar rank if paired with the same GPU, or a stronger CPU might push the combo higher. The 0.1% deltaPct to the Core i7-9700 and -0.2% to the Core i7-8700 indicates that the i5-12400 is not a limiting factor in most scenarios, but the 229th rank out of 1769 shows there is room for improvement with a more powerful processor.

CPU Role

The Intel Core i5-12400 has 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its 18 MB of shared L3 cache and 1.25 MB per-core L2 cache are adequate for a simulation game that may rely on complex calculations. The CPU’s Cinebench R23 multicore score of 15935 and single-core score of 2249 show solid performance, but the data from Pc Building Simulator suggests that the CPU is not the primary constraint at most settings.

At 1080p Low, the system hits 349.4 FPS, which is likely near the CPU’s practical limit. The Passmark single-thread score of 3456 and 3DMark single-thread score of 910 indicate that the i5-12400 is capable, but at such high frame rates, the CPU’s architecture may introduce a bottleneck. The 3DMark 16-thread score of 5873 and max-thread score of 5890 show that multi-threaded performance is only slightly better than 8-thread performance (4745), meaning the extra threads are not fully utilized in this game.

At 1440p and 4K, the CPU’s role diminishes. The frame rates are lower, giving the CPU more time to process game logic, and the GPU becomes the limiting factor. The CPU’s 65 W TDP and 10 nm process node (Alder Lake-S) mean it runs efficiently, and its support for DDR4 and DDR5 memory, along with PCIe Gen 5 lanes, ensures it does not bottleneck the RTX 4070 Ti’s PCIe 4.0 interface. The i5-12400’s boost clock of 4.40 GHz is sufficient for this game, and the data confirms that the CPU is not a weak link except at extreme 1080p frame rates.

The CPU’s nearest rivals in synthetic benchmarks are all within 0.4% of its average score, which means the i5-12400 performs comparably to the Core i7-9700, Core i7-8700, and Core i5-11600K. In Pc Building Simulator, this translates to consistent frame delivery, as the CPU rarely becomes the limiting factor. The 229th combo rank out of 1769 reflects the CPU’s capability when paired with a strong GPU, but the data shows that for players seeking maximum frame rates at 1080p, a higher-clocked CPU might yield better results. For 1440p and 4K, the i5-12400 is more than adequate, and its performance is well-matched to the RTX 4070 Ti.
