# Resolution Scaling

The data shows a clear and expected pattern: frame rates decline as resolution increases, but the magnitude of the drop varies by settings preset. From 1920x1080 to 3840x2160, the average FPS at High settings falls from 249.1 to 83.7, a reduction of 165.4 FPS or 66.4%. At Low settings, the same resolution jump sees FPS drop from 350.8 to 165.3, a 52.9% decrease. The Ultra preset shows the steepest relative decline, going from 236.9 at 1080p to 77.5 at 4K, a 67.3% reduction.

These scaling patterns indicate that the RTX 5080 is the primary limiting component at 4K. At 1080p, the GPU is so powerful that it can render frames faster than the CPU can feed it, particularly at Low and Medium settings where the 350.8 and 306.8 FPS figures approach the practical ceiling for a six-core processor. The gap between 1080p and 1440p is smaller than the gap between 1440p and 4K, which suggests that the GPU's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth are well-utilized as resolution scales, but the CPU becomes less of a factor at higher pixel counts.

The most telling data point is the 4K Low setting result of 165.3 FPS. At this setting, the GPU is heavily underutilized relative to its peak capabilities, yet it still produces triple-digit frame rates. This confirms that the RTX 5080 is not the bottleneck at lower resolutions; instead, the i5-12400F's six cores and 12 threads limit the maximum achievable frame rate. At 4K Ultra, however, the 77.5 FPS figure shows the GPU is working near its limits, as the gap between High and Ultra settings at 4K (83.7 vs. 77.5) is proportionally larger than at 1080p (249.1 vs. 236.9).

# Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 350.8 FPS, Medium yields 306.8 FPS, High reaches 249.1 FPS, and Ultra drops to 236.9 FPS. The spread from Low to Ultra is 113.9 FPS, a 32.5% reduction. These numbers indicate that even at the most demanding preset, the system has enough headroom for high-refresh-rate monitors.

At 2560x1440, performance remains very strong. Low settings hit 300 FPS, Medium reaches 223.9 FPS, High comes in at 159.1 FPS, and Ultra drops to 146.7 FPS. The difference between Low and Ultra is 153.3 FPS, a 51.1% reduction. The transition from Medium to High at 1440p is notable, with a 64.8 FPS drop, suggesting that High settings introduce significant shading and geometry workloads.

At 3840x2160, the system still delivers smooth gameplay. Low settings produce 165.3 FPS, Medium reaches 113.5 FPS, High yields 83.7 FPS, and Ultra drops to 77.5 FPS. The gap between Medium and High is 29.8 FPS, and between High and Ultra is only 6.2 FPS, indicating diminishing returns from High to Ultra at 4K. Across all resolutions, the Ultra preset consistently delivers the lowest frame rates, but never falls below 77.5 FPS, which remains well above playable thresholds.

# Settings Recommendations

Based on the measured FPS data, the optimal preset for this combo depends on the target resolution. At 1920x1080, Ultra settings are the clear choice, as the 236.9 FPS average still provides an exceptionally smooth experience while maximizing visual fidelity. The gap between High and Ultra at 1080p is only 12.2 FPS, so there is no meaningful reason to sacrifice quality.

At 2560x1440, High settings (159.1 FPS) offer the best balance. Ultra drops to 146.7 FPS, which is still playable, but the 12.4 FPS difference does not justify the extra visual load. Medium settings (223.9 FPS) are overkill for most displays, as 159.1 FPS already exceeds the refresh rate of most 1440p monitors. For 60 Hz displays, Ultra is viable, but for high-refresh panels, High is the sweet spot.

At 3840x2160, High settings (83.7 FPS) are the recommended preset. This delivers a smooth 4K experience without the marginal visual gains of Ultra, which only improves FPS by 6.2 FPS over the next step down. Medium (113.5 FPS) is a fallback for users who prioritize frame rate over quality, but the 29.8 FPS difference between Medium and High suggests that High provides a significant visual upgrade for a modest performance cost. Low settings at 4K (165.3 FPS) are unnecessary, as even High exceeds the 60 FPS threshold by a wide margin.

# CPU Role

The Intel Core i5-12400F is a six-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, with 18 MB of shared L3 cache. The CPU's benchmark scores are solid: it achieves 16,518 in Cinebench R23 multi-core and 2,332 in single-core, with a 3DMark max-thread score of 5,912. Its average benchmark score of 19,221 places it in the 77th percentile of all CPUs, and it trades blows with the Intel Core i7-8700K (0.1% ahead) and AMD Ryzen 5 7533HS (0.7% behind).

In Pc Building Simulator, the CPU's role is most apparent at lower resolutions. At 1080p Low, the 350.8 FPS figure suggests the CPU is near its limit, as frame rates do not scale proportionally with resolution decreases beyond this point. The 12 threads handle the game's simulation logic, but the data indicates that the CPU becomes a bottleneck only when the GPU is severely underutilized. At 4K, the CPU's impact is minimal, as the GPU dominates the workload. The 65 W TDP and dual-channel memory support (DDR4/DDR5) make this a mainstream part, but the benchmark results show it is more than adequate for this title.

# GPU Role

The NVIDIA GeForce RTX 5080 is a Blackwell 2.0 architecture GPU with 10,752 shading units, 336 texture mapping units, and 112 raster output units. It features 84 RT cores and 336 tensor cores, with a boost clock of 2617 MHz. The 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, and the GPU's FP32 throughput is 56.28 TFLOPS. Its average benchmark score of 59,188 places it in the 89th percentile of all GPUs, and it leads its nearest rival, the Intel Arc A570M, by 1.6%.

The GPU is the dominant component in this pairing, as evidenced by the measured FPS data. At 4K Ultra, the 77.5 FPS average shows the GPU working hard, while at 1080p Low, the 350.8 FPS result demonstrates its raw capability. The 960.0 GB/s bandwidth ensures that texture streaming at 4K does not cause stutter, and the 16 GB VRAM capacity is never exceeded at any tested setting. The RTX 5080's 89th percentile ranking indicates that it is a top-tier part, and the data confirms that it is the primary driver of this combo's 91st-place rank in the game. The GPU's 360 W TDP and PCIe 5.0 x16 interface are consistent with a high-end part, and its performance in Pc Building Simulator shows no signs of thermal or bandwidth throttling based on the consistent frame rates across resolutions.
