Pc Building Simulator

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 3080 delivers a remarkably consistent gaming experience in Pc Building Simulator, holding a 71st percentile ranking among all tested combinations. The data reveals a system that is heavily GPU-bound at higher resolutions, yet exhibits enough CPU headroom to produce exceptional frame rates at 1080p. This analysis breaks down the measured performance across resolutions and settings, clarifying the role each component plays.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly identifies the GPU as the primary limiting factor at higher resolutions. At High settings, the average frame rate drops from 175.7 FPS at 1920x1080 to 109.6 FPS at 2560x1440, representing a 37.6% reduction. Scaling further to 3840x2160 yields 60.7 FPS, a 44.6% drop from the 1440p figure and a 65.5% decrease from the 1080p result. This steep decline in performance as pixel count increases indicates that the RTX 3080's rendering throughput is being fully taxed at 4K, with the CPU no longer able to compensate.

The pattern holds across all presets. At Low settings, performance falls from 348.7 FPS at 1080p to 223.3 FPS at 1440p, then to 117.0 FPS at 4K. The scaling from 1080p to 4K at Low settings shows a 66.4% reduction, which is slightly less severe than the 65.5% drop at High, but still points to the same conclusion. At Ultra settings, the numbers descend from 165.6 FPS at 1080p to 106.8 FPS at 1440p and finally to 55.3 FPS at 4K, a 66.6% overall reduction. The consistency of this scaling pattern across all settings confirms that resolution, not graphical complexity, is the dominant factor in performance degradation.

The 4K Ultra result of 55.3 FPS is barely above playable thresholds, while the 4K High result of 60.7 FPS just clears 60 FPS. This indicates that users targeting 4K should expect to use High settings or lower to maintain smooth gameplay. The 1440p results are far more comfortable, with even Ultra settings producing 106.8 FPS, suggesting that this resolution is the sweet spot for this combination. At 1080p, the system is almost certainly CPU-limited at Low and Medium settings, as the GPU has ample headroom to render frames far faster than the processor can feed it.

CPU Role

The Intel Core i5-12400F provides the foundational processing power for this combination, featuring 6 cores and 12 threads. Its base clock of 2.50 GHz and boost clock of 4.40 GHz allow it to handle the simulation's logic and physics calculations without becoming a bottleneck at standard resolutions. The processor's 18 MB of shared L3 cache helps maintain responsive performance during complex system-building scenarios.

Benchmark data places this CPU in the 77th percentile of all processors, with an average benchmark score of 19221. Its closest rival, the Intel Core i7-8700K, scores 19210, just 0.1% lower, showing that the i5-12400F offers competitive multi-threaded performance against older flagship parts. The single-thread score of 3481 in Passmark and 2332 in Cinebench R23 indicates strong per-core performance, which is crucial for a simulation game that may not perfectly scale across all 12 threads.

The measured frame rates reveal the CPU's limitations primarily at 1080p. At Low settings, the system reaches 348.7 FPS, but this is likely near the ceiling of what the CPU can sustain. The gap between Low and Medium at 1080p is 99 FPS (348.7 to 249.8), while the gap between Medium and High is 74 FPS (249.8 to 175.7). These diminishing returns suggest that once the GPU is no longer the constraint, the CPU's ability to process game logic becomes the limiting factor. The 3DMark scores, including 5912 for max threads and 909 for single thread, show balanced performance that supports high frame rates without extreme multi-threading demands.

GPU Role

The NVIDIA GeForce RTX 3080 is the dominant component in this pairing, equipped with 10 GB of GDDR6X memory across a 320-bit bus, providing 760.3 GB/s of bandwidth. Its boost clock of 1710 MHz and 8704 shading units deliver substantial raw compute power, rated at 29.77 TFLOPS for FP32 operations. The GPU's 80th percentile ranking among all graphics cards, with an average benchmark score of 35787, places it slightly above the AMD Radeon RX 7900 GRE, which scores 36101 (0.9% higher), and the NVIDIA GeForce RTX 5070 Ti Mobile, which scores 35435 (1.0% lower).

The GPU's role becomes evident when examining the 4K results. At 4K Ultra, the average frame rate of 55.3 FPS demonstrates that the RTX 3080 is working at its limit, with the 10 GB VRAM likely fully utilized at this resolution and preset. Dropping to High settings at 4K improves performance to 60.7 FPS, a 9.8% gain, while Medium settings produce 84.3 FPS, a 52.4% improvement over Ultra. These substantial gains from reducing settings confirm that the GPU's memory bandwidth and compute resources are the primary constraints at 4K.

At 1440p, the GPU has more headroom. Ultra settings yield 106.8 FPS, which is 93% faster than the 4K Ultra result. The RTX 3080's architecture, based on the GA102 chip with 28,300 million transistors on an 8 nm process, provides enough bandwidth to maintain high frame rates at this resolution. The 3DMark Steel Nomad DX12 score of 4407 and Passmark G3D score of 25086 further validate the GPU's capability to handle demanding workloads. However, the 4K results indicate that this GPU is best suited for 1440p gaming or 4K at reduced settings.

Measured FPS Breakdown

The measured frame rates provide a complete picture of performance across all settings and resolutions. At 1920x1080, Low settings achieve 348.7 FPS, Medium settings reach 249.8 FPS, High settings produce 175.7 FPS, and Ultra settings deliver 165.6 FPS. The spread from Low to Ultra is 183.1 FPS, showing that graphical settings have a significant impact at this resolution, but even the lowest result is far above playable thresholds.

At 2560x1440, the results are 223.3 FPS for Low, 159.7 FPS for Medium, 109.6 FPS for High, and 106.8 FPS for Ultra. The gap between Low and Ultra narrows to 116.5 FPS, and the difference between High and Ultra shrinks to just 2.8 FPS, indicating that the GPU is becoming the limiting factor as resolution increases. All 1440p results remain comfortably above 100 FPS, making this the recommended resolution for high-refresh-rate monitors.

At 3840x2160, Low settings produce 117.0 FPS, Medium settings yield 84.3 FPS, High settings manage 60.7 FPS, and Ultra settings drop to 55.3 FPS. The scaling from Low to Ultra shows a 52.8% reduction in frame rate, confirming that the GPU is the primary constraint. The jump from Medium to High costs 23.6 FPS, while the jump from High to Ultra costs only 5.4 FPS, suggesting that the Ultra preset offers diminishing returns at this resolution. The 4K results range from playable at Low and Medium to borderline at High and Ultra, making 4K gaming possible but requiring careful settings management.
