# Pc Building Simulator: Intel Core i5-12400 + NVIDIA GeForce RTX 3080 Ti

Pc Building Simulator, a simulation title from 2019, presents an unusual workload where system assembly logic and 3D rendering coexist. The benchmark data for this Intel Core i5-12400 and NVIDIA GeForce RTX 3080 Ti combination reveals a configuration that scales predictably across resolutions, with the GPU clearly dominating performance curves. This analysis draws exclusively from measured FPS data and component specifications.

Resolution Scaling

The measured FPS data shows a steep and consistent decline as resolution increases, which is classic behavior for a GPU-bound scenario in a simulation game. At 1920x1080 with High settings, the combo delivers 183 FPS average. Moving to 2560x1440 High drops that to 115 FPS, a reduction of 68 FPS or roughly 37%. At 3840x2160 High, the average falls further to 60 FPS, representing another 55 FPS decline from 1440p. This pattern—where each resolution step roughly halves the frame rate headroom—indicates the RTX 3080 Ti's rendering pipeline is the primary constraint, not the CPU.

The scaling from Low to Ultra settings at each resolution reinforces this interpretation. At 1920x1080, Low settings produce 349 FPS, while Ultra yields 174 FPS—exactly half. The 1440p Low result of 231 FPS versus 110 FPS at Ultra maintains a similar 2.1x ratio. At 4K, Low hits 121 FPS and Ultra drops to 57 FPS, again roughly a 2.1x spread. This consistent ratio across resolutions suggests the game's settings scale uniformly with GPU workload, and the processor is keeping pace even at the highest frame rates.

The frame time data available for Medium settings provides additional insight. At 1080p Medium, the average FPS is 259 with a minimum of 220 and maximum of 298, a spread of 78 FPS. At 1440p Medium, the average is 163 with min/max of 139/188, a 49 FPS spread. At 4K Medium, the average is 85 with min/max of 73/98, just 25 FPS apart. This narrowing variance at higher resolutions is a hallmark of GPU-bound performance: when the GPU is the bottleneck, frame delivery becomes more consistent because the CPU has ample time to prepare frames.

Notably, the 4K Ultra average of 57 FPS sits just below the 60 FPS threshold often cited as a smoothness target. The 4K High average of 60 FPS is exactly at that mark. This indicates that for this simulation game, 4K at High or below is playable, but Ultra settings will push the RTX 3080 Ti past its comfort zone at that resolution. The delta between 1080p Ultra (174 FPS) and 4K Ultra (57 FPS) is a 117 FPS drop, or 67% lower performance—a steep penalty that underscores how resolution scaling taxes this GPU.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing, and the FPS data confirms it. This GPU features 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth. Its base clock is 1365 MHz with a boost clock of 1665 MHz. The memory operates at 1188 MHz with 19 Gbps effective speed. These specifications place the card in the 83rd percentile of all GPUs tested, with an average benchmark score of 41187.

The VRAM capacity is relevant for Pc Building Simulator, which renders detailed PC components and case interiors. At 4K Ultra, the game demands significant memory resources, and the 12 GB frame buffer appears sufficient to avoid stutters—the measured 57 FPS average at 4K Ultra, while low, is stable. The GPU's 80 RT cores and 320 tensor cores are not heavily utilized in this simulation title, which focuses on rasterized rendering of static scenes and component models.

Comparing to nearest rivals, the RTX 3080 Ti's average score of 41187 is 0.8% ahead of the AMD Radeon Pro 5300 (40870), 1.2% behind the NVIDIA Tesla M40 24 GB (41707), and 1.7% behind the Tesla M40 (41897). The GeForce RTX 5070 trails by 2% (40377). These small deltas in synthetic benchmarks do not translate to meaningful differences in this game, where the measured FPS shows the card's real-world capability.

The GPU's 34.10 TFLOPS of FP32 compute and 532.8 GTexel/s texture rate are ample for a simulation game that does not push extreme geometric complexity. The pixel rate of 186.5 GPixel/s helps explain why 4K performance degrades gracefully rather than collapsing. The card's 350 W TDP and suggested 750 W PSU are relevant for builders using this combo in the game's context, though the simulation itself does not tax power delivery to the same degree as a modern AAA shooter.

How This Combo Ranks

The combo rank of 940 out of 3723 tested combinations places this configuration in the 74.8th percentile—meaning it outperforms roughly three-quarters of all tested setups for Pc Building Simulator. This ranking is respectable but not elite, reflecting that while the RTX 3080 Ti is a strong GPU, the Core i5-12400 is a mid-range processor that does not boost the combo to the top tier.

Given the game's simulation genre, the ranking suggests that many higher-end configurations with more powerful CPUs achieve better results. The 72nd percentile ranking of the CPU against all CPUs (with an average benchmark score of 18683) aligns closely with the combo's overall position. The GPU, at the 83rd percentile, is the stronger component, yet the pairing does not crack the top 25% of combos.

The nearest CPU rivals show interesting dynamics. The AMD EPYC 7643 scores 18697, a 0.1% advantage over the i5-12400. The Intel Core i7-1355U scores 18730, 0.3% higher. The AMD Ryzen AI 5 330 scores 18811, 0.7% higher. The Intel Core i3-14100F scores 18519, which is 0.9% lower. These sub-1% deltas indicate the i5-12400 sits in a tightly contested performance band, and swapping to any of these rivals would produce negligible FPS changes in this game.

The GPU's nearest rivals similarly cluster closely. The Tesla M40 24 GB is 1.2% ahead, the Tesla M40 is 1.7% ahead, and the Radeon Pro 5300 is 0.8% behind. The RTX 5070 is 2% behind. None of these alternatives would meaningfully alter the measured FPS in Pc Building Simulator. The combo's rank is therefore more a function of the CPU's mid-pack position than any deficiency in the GPU.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor from the Alder Lake architecture, built on Intel's 10 nm process. It has a base clock of 2.50 GHz and a boost clock of 4.40 GHz. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3. This CPU supports DDR4 and DDR5 memory in dual-channel configuration and connects via PCIe Gen 5 with 16 lanes. Its 65 W TDP makes it a power-efficient choice.

In Pc Building Simulator, the CPU's role is secondary to the GPU, as the game's rendering workload dominates. The measured FPS at 1080p Low (349 FPS average) demonstrates that the i5-12400 can feed the RTX 3080 Ti with enough data to achieve very high frame rates. The single-thread performance, indicated by a 3dmark single-thread score of 910 and a Cinebench R23 single-core score of 2257, is sufficient for the game's simulation logic.

The CPU's multi-threaded capabilities, shown in a Cinebench R23 multicore score of 15989 and a Passmark multithread score of 18747, are more than adequate for a game that does not heavily utilize parallel processing. The 3dmark 16-thread score of 5873 and max-thread score of 5890 suggest that additional cores beyond the 6 physical ones provide minimal scaling, which is typical for simulation games that rely on a few primary threads.

The CPU's 72nd percentile ranking against all CPUs, with an average benchmark score of 18683, places it in the upper-mid range. Its nearest rival, the AMD EPYC 7643, scores 18697—a 0.1% difference that is statistically negligible. The Intel Core i7-1355U is 0.3% higher, and the AMD Ryzen AI 5 330 is 0.7% higher. The Intel Core i3-14100F is 0.9% lower. These tight margins mean that in Pc Building Simulator, the specific CPU choice among these rivals would not change the measured FPS in any meaningful way.

The CPU's 65 W TDP and 10 nm process node contribute to its efficiency, but the game's performance is not constrained by power delivery or thermals. The integrated UHD Graphics 730 is present but unused in this configuration with a discrete GPU. The CPU's memory support for both DDR4 and DDR5 offers flexibility, though the game's performance does not appear sensitive to memory bandwidth given the GPU-bound nature of the workload.

Measured FPS Breakdown

The measured FPS data covers four resolutions and four settings levels, providing a complete picture of performance scaling.

At 1920x1080, the results are: Low settings produce an average of 349 FPS. Medium settings yield 259 FPS average, with a minimum of 220 and maximum of 298. High settings deliver 183 FPS average. Ultra settings drop to 174 FPS average. The progression from Low to Ultra shows a 50% reduction in frame rate, from 349 to 174 FPS, which is a linear scaling with settings intensity.

At 2560x1440, the pattern continues: Low settings average 231 FPS. Medium settings average 163 FPS, with a minimum of 139 and maximum of 188. High settings average 115 FPS. Ultra settings average 110 FPS. The drop from Low to Ultra is from 231 to 110 FPS, again roughly a 52% reduction. The 1440p results show that High and Ultra are closely clustered at 115 and 110 FPS, suggesting diminishing returns from Ultra settings at this resolution.

At 3840x2160, the results are: Low settings average 121 FPS. Medium settings average 85 FPS, with a minimum of 73 and maximum of 98. High settings average 60 FPS. Ultra settings average 57 FPS. The 4K data shows a compression of frame rates at the high end: Low to Medium drops 36 FPS, Medium to High drops 25 FPS, and High to Ultra drops just 3 FPS. This indicates that at 4K, Ultra settings provide almost no visual benefit over High for a significant performance cost.

The minimum FPS data for Medium settings shows stability across resolutions: 220 at 1080p, 139 at 1440p, and 73 at 4K. These minimums are all above 60 FPS, indicating that even the most demanding scenes in the game do not cause severe frame drops. The maximum FPS values (298 at 1080p, 188 at 1440p, 98 at 4K) show the ceiling of performance for this combo.

For High and Ultra settings, no minimum or maximum data is available, but the averages provide clear guidance: 1080p High (183 FPS) and Ultra (174 FPS) are both well above typical display refresh rates. 1440p High (115 FPS) and Ultra (110 FPS) are suitable for high-refresh monitors. 4K High (60 FPS) and Ultra (57 FPS) are marginal, at the edge of smoothness for 60 Hz displays. The data suggests that for this simulation game, the optimal balance of visual quality and performance is 1440p High or Ultra, where the combo delivers over 110 FPS with headroom to spare.
