Pc Building Simulator

The Intel Core i5-14400F and NVIDIA GeForce RTX 3080 Ti pairing in Pc Building Simulator delivers a fascinating split personality: the CPU provides ample headroom for high-refresh gaming, while the GPU’s performance scales dramatically with settings and resolution. This combination ranks in the 75th percentile of tested configurations, and the measured frame rates show a system that is clearly GPU-bound at higher presets but CPU-sufficient across the board.

CPU Role

The Core i5-14400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. In synthetic benchmarks, it posts a Cinebench R23 multi-core score of 21,914 and a single-core score of 3,093, placing it in the 88th percentile of all CPUs tested. Its nearest rivals—the Intel Core i7-12800H, AMD Ryzen 5 PRO 7645, and Intel Core i7-13705H—all sit within a 0.2% margin of its average benchmark score of 32,508, indicating that this chip is competitive with a broad range of modern desktop and mobile processors.

In Pc Building Simulator, the CPU’s role is largely to keep up with the GPU, and the data shows it does so without bottlenecking. At 1080p with Low settings, the system produces 365.9 FPS, which is nearly double the 181.1 FPS seen at High settings. This massive jump is not a sign of CPU limitation but rather the GPU being freed from heavier shading work. The 14400F’s 20 MB of shared L3 cache and dual-channel memory support (DDR4 and DDR5) provide sufficient bandwidth for the simulation’s logic, which is not particularly thread-hungry. The CPU’s multi-threaded performance, evidenced by a PassMark multi-thread score of 25,783, ensures that background simulation tasks do not interfere with frame pacing.

When comparing to its nearest CPU rivals, the deltaPct values are essentially zero (0.0% vs. the i7-12800H, 0.2% vs. the Ryzen 5 PRO 7645, and -0.2% vs. both the Ryzen 7 250 and i7-13705H). This means that swapping the 14400F for any of these chips would yield almost identical performance in this game. The CPU’s 65 W TDP and 10 nm process node suggest efficient power delivery, but more importantly, the benchmark results indicate that the processor is not the limiting factor at any resolution tested. The 4.70 GHz boost clock helps maintain high single-thread performance, which is crucial for the game’s UI and component logic, but the real story is that the GPU determines the frame rate ceiling.

GPU Role

The RTX 3080 Ti is the dominant component in this pairing, and its specifications explain the wide variance in measured FPS. Built on the Ampere architecture with an 8 nm process, this GPU features 12 GB of GDDR6X memory on a 384-bit bus, delivering a memory bandwidth of 912.4 GB/s. Its boost clock of 1665 MHz and 10,240 shading units allow it to process massive amounts of pixel data, as reflected in its PassMark G3D score of 26,896 and its 83rd percentile ranking among all GPUs.

The GPU’s nearest rivals include the RTX 3090 (deltaPct -0.5%), AMD Radeon Pro 5300 (-0.9%), RTX 5070 (-1.1%), and Tesla M40 (-1.6%). These small negative deltas mean the 3080 Ti is slightly behind these cards in average benchmark score (41,224), but the in-game results show it is more than capable of handling Pc Building Simulator. At 1080p Ultra, the system hits 172.7 FPS, which is a playable and smooth experience for a simulation title. However, the real test is at 4K, where the GPU’s memory bandwidth and raw compute are stressed.

At 4K Ultra, the average FPS drops to 57.7, which is barely above the 60 FPS threshold. This is a clear indication that the 3080 Ti is working near its limits at this resolution and preset. The 12 GB VRAM is sufficient for the game’s textures, but the 34.10 TFLOPS of FP32 compute is taxed heavily at 3840x2160. Conversely, at 4K Low, the system produces 122.5 FPS, showing that the GPU can handle high resolutions when the shading load is reduced. The 3080 Ti’s memory clock of 1188 MHz (19 Gbps effective) and 186.5 GPixel/s pixel rate are key factors in maintaining these frame rates, but the data suggests that 4K Ultra is the edge of its comfort zone for this title.

Settings Recommendations

The measured FPS rows provide a clear picture of how settings impact performance, and the optimal choice depends on the target resolution. At 1080p, the Medium preset delivers 257.5 FPS, which is more than enough for any display, while High offers 181.1 FPS and Ultra 172.7 FPS. The difference between High and Ultra at 1080p is only 8.4 FPS (a 4.6% drop), making Ultra the best value for visual fidelity without sacrificing smoothness. At 1440p, the Medium preset produces 163.8 FPS, while High drops to 115.5 FPS and Ultra to 108.5 FPS. Here, High is the sweet spot, as it provides a 7 FPS advantage over Ultra while still maintaining a 115 FPS average.

At 4K, the situation changes dramatically. The High preset yields 59.5 FPS, which is just under the 60 FPS target, while Ultra drops to 57.7 FPS. The Medium preset at 88.7 FPS is the clear winner for 4K, as it offers a 49% improvement over High (29.2 FPS more) while still looking respectable. Low settings at 122.5 FPS are an option for competitive play, but they undermine the visual experience of a simulation game. Given that the data shows a 31.2 FPS gap between Medium and High at 4K (88.7 vs. 59.5), the recommendation for 4K users is to stick with Medium settings to ensure a stable frame rate above 60 FPS. For 1440p and 1080p, High and Ultra respectively provide the best combination of image quality and performance, as the GPU has enough headroom to absorb the extra load.

How This Combo Ranks

This specific combination of the Core i5-14400F and RTX 3080 Ti ranks 441st out of 1,769 tested combos in Pc Building Simulator. This places it in the top 25% of all configurations, which is consistent with the GPU’s high-end positioning and the CPU’s solid mid-range performance. The rank is driven almost entirely by the GPU, as the CPU’s benchmark percentile (88th) is slightly higher than the GPU’s (83rd), meaning the processor is not holding back the graphics card.

Compared to other combos, this pairing excels in scenarios where the GPU is fully utilized, such as 1440p and 4K. At 1080p, the CPU’s strong single-thread performance (PassMark single-thread score of 3,723) ensures that the GPU is fed with enough data to hit 365.9 FPS on Low settings. However, the rank of 441 suggests that there are 440 faster combos, likely featuring more powerful GPUs like the RTX 3090 or RTX 5070, which have higher average benchmark scores (41,441 and 41,687, respectively). The 3080 Ti’s deltaPct of -0.5% versus the 3090 indicates that the latter is only marginally faster, so the rank difference is likely due to other factors like CPU pairing or memory configuration.

The data also shows that this combo is well-balanced for a simulation game, where frame rates above 60 FPS are often unnecessary. The 441st rank out of 1,769 is a strong showing, especially considering that many higher-ranked combos may use newer, more expensive hardware. For users with a 1440p monitor, this combo is effectively overkill, as it can push 108.5 FPS on Ultra settings, which is far beyond the refresh rate of most displays.

Resolution Scaling

The FPS drop from 1080p to 4K is the most telling indicator of where the bottleneck lies in this system. At High settings, the average FPS falls from 181.1 at 1080p to 115.5 at 1440p (a 36.2% drop) and then to 59.5 at 4K (a 67.1% drop from 1080p). This scaling pattern is typical of a GPU-bound system, as the CPU’s workload does not change significantly with resolution, but the GPU must render four times as many pixels at 4K compared to 1080p.

The data reveals that the CPU is not the limiting factor, as the FPS drops are proportionally consistent with the pixel count increase. At 1080p Low, the system hits 365.9 FPS, which is likely near the CPU’s maximum frame delivery capability, but at 4K Low, it still manages 122.5 FPS. This suggests that even at the lowest settings, the GPU is still the primary constraint at higher resolutions. The gap between Low and Ultra settings grows with resolution: at 1080p, the difference is 193.2 FPS (365.9 vs. 172.7), but at 4K, it shrinks to 64.8 FPS (122.5 vs. 57.7). This compression indicates that at 4K Ultra, the GPU is hitting its compute limits, while at 1080p Low, the CPU or memory bandwidth may start to play a larger role.

The 1440p results are particularly illustrative of the GPU’s headroom. At Medium, the system produces 163.8 FPS, which is only 37% lower than the 1080p Medium score of 257.5 FPS. This is a smaller drop than the pixel count would suggest (1440p has 78% more pixels than 1080p), indicating that the RTX 3080 Ti is well-suited for 1440p gaming. The 4K Ultra score of 57.7 FPS is the only result that falls below the 60 FPS threshold, and it reinforces the conclusion that this combo is best paired with a 1440p display for a high-refresh experience, or a 4K display if the user is willing to compromise on settings.
