Pc Building Simulator

Pc Building Simulator is a simulation title that stresses system configuration logic more than raw rendering, yet the measured frame rates for the Intel Core i5-12400 paired with the NVIDIA GeForce RTX 5080 reveal a clear performance hierarchy across resolutions and settings. The data shows a combination that scales predictably from 1080p to 4K, with the CPU holding its own in a game that is not typically considered a core-heavy benchmark. This analysis breaks down the measured FPS, the role of each component, and the practical settings for this specific pairing.

Resolution Scaling

The measured FPS data for this pairing shows a steep and consistent drop as resolution increases, which is typical for a GPU-bound scenario. At 1920x1080 with Low settings, the average FPS is 349, which drops to 299 at 2560x1440, and then further to 161 at 3840x2160. This represents a 53.9% reduction in average FPS from 1080p Low to 4K Low, indicating that the rendering workload is scaling directly with pixel count. The pattern is consistent across all settings, with the 1080p to 1440p transition costing roughly 14-18% of performance, while the 1440p to 4K jump is much more severe, costing nearly 46% of the average FPS in the Low preset.

The scaling behavior identifies the RTX 5080 as the primary limiting factor at higher resolutions. At 1080p, the frame rates are exceptionally high, with even the Ultra preset hitting 232 average FPS, which suggests the CPU is still feeding the GPU adequately but the GPU is no longer the bottleneck at this resolution. The shift becomes apparent when moving to 4K, where the Ultra preset drops to 77 average FPS, a 66.8% reduction from the 1080p Ultra score. This steep decline indicates that the GPU's rendering pipeline, specifically its pixel throughput and memory bandwidth, is being saturated at 4K, while the i5-12400's six cores and 12 threads are sufficient to keep up with the simulation's logic.

The min FPS values recorded for Medium settings provide additional insight into this scaling. At 1920x1080 Medium, the min FPS is 261, which drops to 185 at 2560x1440, and then to 97 at 3840x2160. The 4K min FPS of 97 is still above 60, but the gap between the average and min FPS widens from 46 at 1080p to 17 at 4K, suggesting that frame time consistency degrades as resolution increases. This points to the GPU's memory subsystem, with its 960.0 GB/s bandwidth, being a critical factor in maintaining playable frame rates at higher resolutions, particularly when the scene complexity in Pc Building Simulator's workshop environment increases.

FAQ

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this pairing, and its specifications directly explain the measured frame rates. The GPU has 16 GB of GDDR7 memory on a 256-bit bus, delivering 960.0 GB/s of bandwidth. This memory configuration is crucial for Pc Building Simulator, which features a detailed workshop environment with many individual PC components that must be rendered. The 16 GB capacity ensures that even at 4K Ultra, the game's textures and geometry data are fully resident in VRAM, preventing hitches from memory swapping.

The RTX 5080's clock speeds are 2295 MHz base and 2617 MHz boost, with a 30 Gbps effective memory clock. These clocks, combined with 10752 shading units and 112 ROPs, allow for a pixel rate of 293.1 GPixel/s and a texture rate of 879.3 GTexel/s. The pixel rate is particularly relevant for 4K rendering, as it determines how quickly the GPU can fill the screen with pixels. The measured 4K FPS figures, ranging from 77 on Ultra to 161 on Low, align with a GPU that is capable but not overkill for this resolution.

The GPU's benchmark scores show it is positioned at the 87th percentile among all GPUs, with an average score of 56083. Its nearest rivals are all AMD parts, with the RX 9070 GRE being 2.2% faster, while the RX 6750 GRE 12 GB is 0.7% slower. The 5080's DirectX 12 score of 151 and Vulkan score of 255450 suggest that its API efficiency is strong, which matters for a game like Pc Building Simulator that runs on modern rendering APIs. The FP32 compute of 56.28 TFLOPS provides ample headroom for the game's simulation and rendering tasks, but the data indicates that the GPU's memory bandwidth is the more critical factor at higher resolutions, given the steep FPS drop from 1440p to 4K.

Measured FPS Breakdown

At 1920x1080, the pairing delivers extremely high frame rates across all presets. The Low preset averages 349 FPS, Medium averages 307 FPS with a min of 261 and max of 353, High averages 244 FPS, and Ultra averages 232 FPS. The gap between Low and Ultra is 117 FPS, representing a 50.4% reduction. This suggests that at 1080p, the CPU is still able to feed the GPU effectively, and the GPU's rendering capabilities are not fully taxed, as even the Ultra preset maintains over 230 FPS.

Moving to 2560x1440, the frame rates remain high but show more differentiation between presets. Low averages 299 FPS, Medium averages 218 FPS with a min of 185 and max of 250, High averages 154 FPS, and Ultra averages 146 FPS. The spread between Low and Ultra is 153 FPS, a 105% difference, indicating that the GPU is beginning to feel the load of the higher pixel count. The High and Ultra presets are notably closer here, with only an 8 FPS difference, suggesting that the visual enhancements from High to Ultra are less demanding than those from Medium to High.

At 3840x2160, the performance gap narrows further between some presets while widening between others. Low averages 161 FPS, Medium averages 114 FPS with a min of 97 and max of 131, High averages 80 FPS, and Ultra averages 77 FPS. The High and Ultra presets are nearly identical, with only a 3 FPS difference, indicating that the Ultra preset's additional effects are minimal at this resolution. The Medium preset stands out as the most balanced option, with a min FPS of 97 that remains above the 60 FPS threshold for smooth gameplay, while the Low preset's 161 FPS shows that the GPU can still push high frame rates even at 4K when visual fidelity is reduced.

The measured data across all resolutions shows a clear pattern: the i5-12400 and RTX 5080 combination is capable of exceeding 144 FPS at 1080p and 1440p on most presets, but drops below 100 FPS at 4K on High and Ultra. The Medium preset at 4K, with its 114 average FPS and 97 min FPS, represents the best compromise for high-resolution gaming.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor based on the Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. In Pc Building Simulator, which is a simulation game with significant logic and physics calculations, the CPU's role is to manage the simulation state while the GPU handles rendering. The CPU's benchmark scores indicate it is well-suited for this task, with a 3dmark_max_threads score of 5890 and a cinebench_r23_multicore score of 15989, placing it in the 72nd percentile among all CPUs.

The CPU's single-threaded performance is particularly important for this game, as simulation engines often rely on a primary thread for game logic. The i5-12400 scores 910 in 3dmark_single_thread and 2257 in cinebench_r23_singlecore, which are strong numbers for a 12th-gen part. This ensures that the CPU can process the game's simulation steps without becoming a bottleneck, even when the GPU is pushing high frame rates at 1080p. The measured 349 FPS at 1080p Low confirms that the CPU is not limiting the GPU, as the GPU is capable of outputting far more frames if the CPU were the constraint.

The CPU's cache hierarchy, with 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3, provides ample fast memory for the simulation's data structures. The 65W TDP is modest, and the CPU's support for DDR4 and DDR5 memory allows for flexible system configuration. Compared to its nearest rivals, the i5-12400's average score of 18683 is nearly identical to the AMD EPYC 7643 (18697) and Intel Core i7-1355U (18730), with deltas of -0.1% and -0.3% respectively. It is 0.9% ahead of the Intel Core i3-14100F, showing that the i5-12400 sits comfortably in a competitive mid-range segment.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate of the display. For 1080p users with high-refresh monitors, the Ultra preset at 232 average FPS is the best choice, as it provides the highest visual quality while still exceeding 144 FPS for smooth gameplay. The High preset at 244 FPS is also viable, but the Ultra preset's additional visual effects come at a negligible cost of just 12 FPS.

For 2560x1440 users, the Medium preset offers the best balance of visual quality and performance, with an average of 218 FPS and a min of 185 FPS. This ensures that even in complex scenes with many PC components on screen, the frame rate remains above the 144Hz refresh rate of most gaming monitors. The High preset at 154 FPS is also acceptable, but the min FPS data for Medium suggests more stable frame delivery, which is preferable in a simulation game where camera pans can cause sudden load spikes.

For 3840x2160 users, the Medium preset is the clear recommendation, as it delivers 114 average FPS with a min of 97 FPS. This provides a smooth experience that is well above the 60 FPS console standard, while the High and Ultra presets at 80 and 77 FPS respectively are playable but may not be ideal for fast camera movements. The Low preset at 161 FPS is also viable for competitive play, but the visual compromise is significant in a game that is about visual detail.

The data indicates that the RTX 5080 is powerful enough to run Pc Building Simulator at high frame rates on all presets at 1080p and 1440p, but at 4K, users should consider the Medium preset to maintain consistent frame pacing. The Ultra preset at 4K is only 3 FPS lower than High, so the visual benefits of Ultra are nearly free at that resolution, but the jump from Medium to High costs 34 FPS, making Medium the most efficient choice for 4K.
