Pc Building Simulator

The Intel Core i5-12400 and NVIDIA GeForce RTX 4080 combination delivers a striking performance profile in Pc Building Simulator, where the data reveals a simulation title that scales dramatically with both CPU and GPU capabilities. This analysis breaks down the measured frame rates, component roles, and scaling behavior to provide a methodical overview of what this specific pairing offers.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-12400 is a 6-core, 12-thread processor based on the Alder Lake architecture, built on Intel's 10 nm process. It operates with a base clock of 2.50 GHz and a boost clock of 4.40 GHz, with a 65 W TDP. The chip features 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and a shared 18 MB L3 cache. Memory support includes both DDR4 and DDR5 in a dual-channel configuration, with PCIe Gen 5 providing 16 lanes from the CPU.

Benchmark results for the i5-12400 show a solid mid-range standing. Its average benchmark score is 18683, placing it in the 72nd percentile among all CPUs. The Cinebench R23 multi-core score is 15989, while the single-core score is 2257. In PassMark, the multithread score reaches 18747, with single-thread performance at 3456. The 3DMark 16-thread test yields 5873, and the max-thread test scores 5890.

In Pc Building Simulator, the CPU's role appears significant at lower resolutions. At 1080p with Low settings, the combo achieves 349 FPS, which is the highest measured value across all resolution and setting combinations. This suggests that at this resolution, the CPU is capable of feeding the GPU with enough data to reach very high frame rates. As resolution increases, the frame rates drop, indicating that the GPU becomes more of a limiting factor.

The nearest rivals to the i5-12400 in terms of average benchmark score provide context. The AMD EPYC 7643 scores 18697, a delta of -0.1% relative to the i5-12400, meaning the i5 is essentially tied with it. The Intel Core i7-1355U scores 18730, a delta of -0.3%, and the AMD Ryzen AI 5 330 scores 18811, a delta of -0.7%. The Intel Core i3-14100F scores 18519, a delta of 0.9%, meaning the i5-12400 is slightly ahead of it. These close margins indicate that the i5-12400's performance is well within the range of its direct competition.

The data shows that the i5-12400's 12 threads are sufficient for this simulation title, as evidenced by the high frame rates at 1080p. The 3DMark 2-thread score of 1692 and 4-thread score of 3012 indicate strong single and lightly threaded performance, which is often critical for simulation game logic. The boost clock of 4.40 GHz provides the necessary single-core speed for such tasks.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4080 is a high-end graphics card based on the Ada Lovelace architecture, built on TSMC's 5 nm process. It features 16 GB of GDDR6X memory on a 256-bit bus, providing a bandwidth of 716.8 GB/s. The GPU clock runs at a base of 2205 MHz and a boost of 2505 MHz, with memory clocked at 1400 MHz or 22.4 Gbps effective. The card has 9728 shading units, 304 TMUs, and 112 ROPs, along with 76 RT cores and 304 tensor cores. Its compute capabilities include 48.74 TFLOPS of FP32 performance.

The RTX 4080's benchmark results show a strong standing in the GPU hierarchy. Its average benchmark score is 54247, placing it in the 86th percentile among all GPUs. The PassMark G3D score is 34457, while the Geekbench OpenCL score reaches 214739 and Vulkan score hits 263779. The 3DMark Steel Nomad DX12 score is 6567.

In Pc Building Simulator, the GPU's role becomes more pronounced at higher resolutions. At 4K with Ultra settings, the combo achieves 74 FPS, while at 1080p with Ultra settings, it reaches 224 FPS. This scaling indicates that the RTX 4080's 16 GB VRAM is more than sufficient for this title, as even at 4K Ultra, the frame rate remains playable.

The nearest rivals to the RTX 4080 provide context for its performance. The NVIDIA GeForce RTX 4080 SUPER scores 54209, a delta of 0.1%, meaning the RTX 4080 is essentially tied with its SUPER variant. The AMD Radeon Pro W5700X scores 54828, a delta of -1.1%, indicating the RTX 4080 is slightly behind it. The AMD Radeon RX 6750 GRE 12 GB scores 55698, a delta of -2.6%, and the AMD Radeon 8060S scores 55757, a delta of -2.7%. These negative deltas mean the RTX 4080 is behind these rivals in average benchmark score, but the margins are small.

The data suggests that the RTX 4080 is not the primary bottleneck in this game at 1080p, where the CPU appears to be the limiting factor. However, at 4K, the GPU's workload increases, and the frame rates drop accordingly, indicating that the GPU is being pushed harder.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured frame rates show a clear pattern of scaling across resolutions. At 1920x1080 with Low settings, the combo achieves 349 FPS. Moving to 2560x1440 with Low settings, this drops to 297 FPS, a decrease of 52 FPS or approximately 15%. At 3840x2160 with Low settings, the frame rate drops further to 155 FPS, a decrease of 142 FPS from 1080p or approximately 41%.

For Medium settings, the pattern is similar. At 1080p, the average FPS is 307, dropping to 210 at 1440p and 110 at 4K. The drops are 97 FPS (32%) from 1080p to 1440p, and 100 FPS (48%) from 1440p to 4K. These larger percentage drops at higher resolutions indicate that the GPU is becoming more of a limiting factor.

High settings show a similar trend. At 1080p, the average FPS is 235, dropping to 148 at 1440p and 78 at 4K. The drop from 1080p to 1440p is 87 FPS (37%), and from 1440p to 4K is 70 FPS (47%). Ultra settings follow the same pattern: 224 FPS at 1080p, 141 FPS at 1440p, and 74 FPS at 4K.

The scaling behavior reveals that the limiting component shifts with resolution. At 1080p, the frame rates are extremely high, suggesting that the CPU is the primary constraint for reaching even higher numbers. The difference between Low (349 FPS) and Ultra (224 FPS) at 1080p is 125 FPS, which is a significant spread. At 4K, the difference between Low (155 FPS) and Ultra (74 FPS) is 81 FPS, which is proportionally similar but at lower absolute values.

The data indicates that at 1080p, the system is CPU-bound, as even the GPU-heavy Ultra settings cannot push the frame rates as high as the CPU-limited Low settings. At 4K, the system becomes more GPU-bound, as the frame rates drop to ranges that are more typical of GPU-limited scenarios. The RTX 4080's 16 GB VRAM is not a limiting factor here, as even at 4K Ultra, the frame rate remains above 60 FPS.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured frame rates, the optimal settings depend on the target resolution and desired frame rate. At 1080p, all settings provide very high frame rates. Low settings achieve 349 FPS, Medium hits 307 FPS, High reaches 235 FPS, and Ultra delivers 224 FPS. For a gamer with a 144Hz or 240Hz monitor, Medium settings provide a good balance, as the 307 FPS average is well above typical refresh rates, and the measured minimum of 261 FPS ensures smooth gameplay.

At 1440p, the frame rates are still high. Low settings achieve 297 FPS, Medium hits 210 FPS, High reaches 148 FPS, and Ultra delivers 141 FPS. For 1440p, Medium settings are recommended, as the 210 FPS average is sufficient for high-refresh-rate monitors, and the minimum of 179 FPS is still well above 60 FPS. High settings also work well, with 148 FPS being smooth for most displays.

At 4K, the frame rates are lower but still playable. Low settings achieve 155 FPS, Medium hits 110 FPS, High reaches 78 FPS, and Ultra delivers 74 FPS. For 4K, High settings are recommended, as the 78 FPS average is above the 60 FPS threshold for smoothness, and the visual quality improvement over Medium is notable. Ultra settings are also viable, with 74 FPS being acceptable for many players, but the 4 FPS difference from High is minimal.

The data shows that Medium settings provide the best overall experience across resolutions, as they offer a significant frame rate boost over High and Ultra while maintaining reasonable visual quality. The measured minimum and maximum values for Medium settings (261-353 FPS at 1080p, 179-242 FPS at 1440p, 93-126 FPS at 4K) indicate consistent performance without major frame drops.
