Pc Building Simulator

The Intel Core i5-12400F 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. Its 18 MB of shared L3 cache and 10 nm process node are typical of the Core 12th Gen series. In the context of Pc Building Simulator, a simulation title that often involves physics calculations and logic for component interactions, the CPU's multi-threaded performance is relevant. The benchmark data shows a Cinebench R23 multicore score of 16518 and a Passmark multithread score of 19433. This places the CPU at the 77th percentile among all CPUs, with an average benchmark score of 19221. The closest rival is the Intel Core i7-8700K, which scores 19210, a delta of just 0.1%—essentially a statistical tie. This suggests that while the 12400F is not a high-end enthusiast part, its 12 threads provide sufficient parallel processing headroom for a game that simulates hardware behavior, ensuring that it does not bottleneck the system in most scenarios. The data implies that the CPU's single-thread performance, reflected in a Passmark single-thread score of 3481, is also adequate for the game's core logic loop, which is often the primary constraint in simulation titles.

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

The NVIDIA GeForce RTX 5070 is the dominant component in this pairing, featuring 12 GB of GDDR7 memory on a 192-bit bus, which yields a bandwidth of 672.0 GB/s. Its base clock is 2325 MHz with a boost clock of 2512 MHz, and the card is built on the Blackwell 2.0 architecture at a 5 nm process node. The GPU's 6144 shading units and 80 ROPs contribute to a pixel rate of 201.0 GPixel/s, while its FP32 performance is rated at 30.87 TFLOPS. In the benchmark suite, the RTX 5070 achieves a Passmark G3D score of 29137, placing it at the 83rd percentile among all GPUs. Its average benchmark score of 41687 is closely matched by the AMD Radeon Pro 5300, which scores 41610 (a 0.2% delta), and the NVIDIA GeForce RTX 3090, which scores 41441 (a 0.6% delta). For Pc Building Simulator, the GPU's role is primarily visual, but the data shows it is far from a limiting factor. The measured FPS at 4K Ultra is 59.6, while at 1080p Low it reaches 353.1. This wide spread indicates that the GPU is powerful enough to push frame rates to extreme levels at lower resolutions, and it is only at the highest settings and resolutions that its workload becomes substantial. The 12 GB VRAM is ample for the game's textures and rendering needs, as the performance drop from Medium to Ultra at 4K (95.3 down to 59.6) suggests a memory bandwidth or fill-rate constraint rather than a capacity issue.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a clear picture of performance scaling across resolutions and settings. At 1920x1080, the average frame rates are exceptionally high: Low settings yield 353.1 FPS, Medium drops to 282.3 FPS, High reduces to 199.1 FPS, and Ultra settles at 188.4 FPS. This shows a 46.6% reduction in frame rate from Low to Ultra at 1080p, but even the lowest figure is far beyond what a 60Hz or 144Hz monitor can display. Moving to 2560x1440, the averages are 251.2 FPS at Low, 176.2 FPS at Medium, 123.6 FPS at High, and 120.6 FPS at Ultra. The drop from 1080p Ultra to 1440p Ultra is 35.9%, indicating that the GPU is still well ahead of the CPU at this resolution. At 3840x2160, the trend continues: Low produces 134.1 FPS, Medium yields 95.3 FPS, High manages 62.9 FPS, and Ultra falls to 59.6 FPS. The 4K Ultra figure is just below the 60 FPS threshold, which is notable. The pattern across all resolutions is consistent: the delta between High and Ultra is small (e.g., 62.9 vs 59.6 at 4K), while the delta between Low and Medium is much larger (134.1 vs 95.3 at 4K). This suggests that the Ultra preset introduces diminishing returns relative to the performance cost.

FAQ

Q: Is the Intel Core i5-12400F a bottleneck for the RTX 5070 in this game?

A: The data indicates no significant bottleneck. The CPU's Cinebench R23 multicore score of 16518 and its 77th percentile ranking are sufficient to keep up with the GPU. The FPS scaling from 1080p to 4K is smooth, and the CPU's nearest rival, the i7-8700K, scores nearly identically (19210 vs 19221), showing the 12400F is not a weak link.

Q: What is the best resolution for this combo to hit 60 FPS?

A: At 4K Ultra, the average FPS is 59.6, which is just below 60. For a guaranteed 60+ FPS experience, 4K High provides 62.9 FPS, while 1440p Ultra gives 120.6 FPS and 1080p Ultra gives 188.4 FPS. The data shows 4K High is the highest setting/resolution that comfortably exceeds 60 FPS.

Q: How does the RTX 5070 compare to the RTX 3090 in this context?

A: The RTX 5070 has an average benchmark score of 41687, while the RTX 3090 scores 41441, a delta of 0.6% in favor of the 5070. This is a marginal difference, meaning the 5070 is effectively on par with the older 3090 in raw compute, though it uses a newer architecture and GDDR7 memory.

Q: Why is the performance difference between High and Ultra settings so small at 4K?

A: At 3840x2160, High yields 62.9 FPS and Ultra yields 59.6 FPS, a difference of only 3.3 FPS. This suggests that the Ultra preset adds visual features that are not heavily taxing on the GPU, or that the game's engine is already maxed out at High, making the Ultra preset a minor increment rather than a significant jump.

Q: Does the CPU's single-thread performance matter for this game?

A: Yes, the Passmark single-thread score of 3481 and the 3DMark single-thread score of 909 show that the 12400F has solid single-core capability. Since simulation games often rely on a main thread for game logic, this strong single-thread performance is critical for maintaining high frame rates, as evidenced by the 353.1 FPS at 1080p Low.

Q: What is the FPS drop from 1080p to 4K at Ultra settings?

A: The average FPS at 1080p Ultra is 188.4, while at 4K Ultra it is 59.6. This represents a 68.4% reduction in frame rate, indicating that the GPU is the primary scaling factor, as the CPU workload remains constant while the pixel count quadruples.

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

For the best balance of visual quality and frame rate, the measured data points to the High preset at 1440p as the optimal choice. At 2560x1440, the High preset delivers 123.6 FPS, which is well above the 60 FPS threshold and provides a smooth experience on high-refresh-rate monitors. The jump from High to Ultra at 1440p yields only a 3 FPS difference (120.6 vs 123.6), so the Ultra preset offers no meaningful advantage. At 4K, the High preset at 62.9 FPS is the only setting that breaks 60 FPS, making it the recommended choice for 4K users. For 1080p users, the High preset at 199.1 FPS is more than sufficient, and the Ultra preset at 188.4 FPS is also viable if the user prioritizes maxed-out visuals, as the 10.7 FPS difference is negligible. The data suggests that choosing Ultra over High is rarely justified in this game, as the performance cost is high relative to the visual gain. The Medium preset at 4K (95.3 FPS) is a strong option for those seeking a high frame rate at 4K without dropping to Low, but High at 4K is the sweet spot for 60+ FPS gameplay.

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

The FPS scaling from 1080p to 4K reveals a classic GPU-bound scenario. At Low settings, the average FPS drops from 353.1 at 1080p to 134.1 at 4K, a 62.0% reduction. At Medium settings, the drop is from 282.3 to 95.3, a 66.2% reduction. At High settings, the drop is from 199.1 to 62.9, a 68.4% reduction. At Ultra settings, the drop is from 188.4 to 59.6, a 68.4% reduction. This consistent ~62-68% decline across all settings is a hallmark of a GPU-limited system, where the CPU's performance remains constant while the GPU's workload increases with pixel count. The fact that the percentage drop is similar across settings indicates that the CPU is not introducing a bottleneck at higher resolutions—if it were, the FPS would plateau or drop more steeply at lower resolutions where the CPU is the limiting factor. The data shows that at 1080p Low, the system achieves 353.1 FPS, which is far beyond the CPU's ability to feed frames, but even at this extreme, the CPU maintains the frame rate without capping it. This confirms that the RTX 5070 is the primary limiter at all resolutions, and the i5-12400F provides more than enough headroom for the game's simulation logic. The 4K Low figure of 134.1 FPS is particularly telling—it shows the GPU can handle the pixel load at low settings, but the CPU still keeps up, proving the balance of this combo is well-suited for the game.
