Pc Building Simulator

The Intel Core i5-12400F paired with the AMD Radeon RX 9070 delivers a performance curve in Pc Building Simulator that clearly separates the GPU's raw capabilities from the CPU's ceiling. At 1080p, the system produces extremely high frame rates, but the scaling to higher resolutions reveals where the Radeon RX 9070 becomes the primary constraint. The measured data shows a drop from 348.4 FPS at 1080p Low to 111.5 FPS at 4K Low, which is a 68% reduction. This is a massive hit, but it is expected for a simulation title where the camera often renders complex shop interiors and part models. The 1440p results sit in a comfortable middle ground, with Low settings hitting 216.8 FPS and Ultra still maintaining 101.6 FPS. At 4K, the Ultra preset drops to 54.7 FPS, which is identical to the High preset’s 54.7 FPS, indicating that the GPU is fully saturated and the extra settings from High to Ultra cost nothing in this specific scene. The data suggests that the RX 9070 is the limiting component at 4K, while the 12400F has enough headroom to push much higher frame rates at lower resolutions.

Resolution Scaling

The frame rate scaling from 1080p to 4K is steep and tells a clear story about bottleneck behavior. At 1080p Low, the combo achieves 348.4 FPS, which is a very high number that suggests the CPU can feed the GPU far beyond typical monitor refresh rates. Moving to 1440p Low, the FPS drops to 216.8, a 38% decrease, which is consistent with the GPU taking on a heavier pixel workload. At 4K Low, the average falls to 111.5 FPS, another 49% drop from 1440p. This progressive decline shows that the RX 9070 is doing most of the heavy lifting at higher resolutions, while the 12400F’s 6 cores and 12 threads are not the limiting factor until you reach extremely high frame rates. For High settings, the pattern is similar: 171.5 FPS at 1080p, 107.6 FPS at 1440p, and 54.7 FPS at 4K. The 4K High result being identical to 4K Ultra suggests that the GPU's rendering pipeline is maxed out, not the CPU. The data indicates that for competitive or high-refresh gameplay, 1080p is the sweet spot, while 4K players will need to accept lower presets to stay above 60 FPS. The 4K Medium setting at 83.8 FPS is the most balanced option for resolution-focused users.

How This Combo Ranks

Out of 1769 tested combinations in Pc Building Simulator, this pairing ranks 567th. That places it in the top third of all combos, which is respectable for a mid-range CPU paired with a high-end GPU. The rank reflects the fact that the RX 9070 is a strong performer, but the 12400F holds the combo back from the top tiers. The CPU's percentile ranking is 77th among all CPUs, while the GPU sits at the 79th percentile among all GPUs, so neither component is a weak link in the absolute sense, but the CPU is slightly less dominant than the GPU. The nearest rivals for the CPU include the Intel Core i7-8700K, which scores a near-identical average benchmark score at a delta of 0.1%, and the AMD EPYC 7773X, which is 1.3% ahead. For the GPU, the closest competitor is the NVIDIA A2, which is 0.2% faster in average score, and the Quadro GV100, which trails by 0.3%. These deltas are small, meaning the 12400F is performing exactly as expected for its class, and the RX 9070 is competitive with other high-end cards in synthetic benchmarks. In-game, the 567th rank out of 1769 suggests that many stronger CPU-GPU pairings will outperform this combo in Pc Building Simulator, but it also means there are over 1200 combos that are slower.

FAQ

Q: Is the Intel Core i5-12400F strong enough for the RX 9070 in this game?

A: The data shows the CPU is not the primary bottleneck at most settings. At 1080p Low, the combo hits 348.4 FPS, which is far beyond typical display refresh rates, indicating the CPU can feed the GPU adequately. The GPU becomes the limit at 4K, where FPS drops to 54.7 on Ultra.

A: For 60 FPS, 4K Medium is the safest choice, with an average of 83.8 FPS. At 1440p, all presets exceed 101 FPS, with Low hitting 216.8 FPS. At 1080p, even Ultra stays above 165 FPS, so any resolution can hit 60 FPS, but 4K Ultra is the only setting that falls below 60 FPS.

Q: How does the CPU compare to its nearest rivals in synthetic benchmarks?

A: The 12400F has an average benchmark score of 19221, which is 0.1% higher than the Intel Core i7-8700K and 0.3% higher than the Intel Core i5-1335U. It trails the AMD Ryzen 5 7533HS by 0.7% and the AMD EPYC 7773X by 1.3%. These differences are minor, so real-world gaming performance will be similar.

Q: Does the GPU have enough memory bandwidth for 4K textures?

A: The RX 9070 has 16 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 644.6 GB/s. In Pc Building Simulator, this is sufficient, as the 4K High and Ultra presets both hit 54.7 FPS, suggesting memory is not a limiting factor at this resolution.

Q: Are the Low and Ultra presets very different in performance?

A: Yes, the gap is large. At 1080p, Low delivers 348.4 FPS while Ultra delivers 165 FPS, a difference of 183.4 FPS. At 4K, the gap narrows to 56.8 FPS (111.5 vs 54.7), showing that the GPU is the constraint at higher resolutions, not the settings.

Q: What is the CPU's clock speed and core count?

A: The 12400F has 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. It has 18 MB of shared L3 cache and supports DDR4 and DDR5 memory. The boost clock is critical for the high frame rates seen at 1080p.

Settings Recommendations

The measured FPS rows show a clear hierarchy of presets, and the best choice depends on the target resolution. For 1080p users, the Ultra preset is the best option because it delivers 165 FPS, which is still well above 144 Hz refresh rates, and the visual quality improvement over High (171.5 FPS) or Medium (243.1 FPS) is worth the performance cost. The Low preset at 348.4 FPS is unnecessary unless chasing extreme frame rates for competitive play. At 1440p, the High preset at 107.6 FPS is the sweet spot for most users, as it provides a smooth experience on 100 Hz or 120 Hz monitors. The Ultra preset at 101.6 FPS is also viable, and the difference between High and Ultra is only 6 FPS, so choosing Ultra is recommended for better visuals. The Medium preset at 156.4 FPS is overkill for most 1440p monitors, and Low at 216.8 FPS is only useful for high-refresh esports-style play. At 4K, the Medium preset at 83.8 FPS is the best choice for a 60 Hz or 75 Hz monitor, as it provides a comfortable margin above 60 FPS. The High and Ultra presets both sit at 54.7 FPS, which is below 60 FPS and may cause noticeable stutter on standard 60 Hz displays. The Low preset at 111.5 FPS is playable but sacrifices too much visual fidelity for a simulation game where part textures matter. Overall, the data recommends Ultra at 1080p, Ultra or High at 1440p, and Medium at 4K as the best balance of performance and quality.

Measured FPS Breakdown

The full set of measured results provides a detailed picture of this combo's behavior. At 1920x1080, the Low preset achieves 348.4 FPS, which is the highest score in the entire dataset. The Medium preset drops to 243.1 FPS, High falls to 171.5 FPS, and Ultra bottoms out at 165 FPS. This shows that the CPU can push very high frame rates at 1080p, but the GPU is still capable of handling the load without bottlenecking. At 2560x1440, the Low preset hits 216.8 FPS, Medium reaches 156.4 FPS, High manages 107.6 FPS, and Ultra delivers 101.6 FPS. The drop from Low to Medium is 60.4 FPS, while the drop from High to Ultra is only 6 FPS, indicating diminishing returns on the highest settings. At 3840x2160, the Low preset achieves 111.5 FPS, Medium drops to 83.8 FPS, and both High and Ultra are locked at 54.7 FPS. The identical High and Ultra scores are notable, as they suggest the GPU is fully saturated and the extra settings do not change the render load. The scaling from 1080p to 4K at Low settings is a 68% reduction, while at Ultra settings it is a 67% reduction, showing a consistent pattern across presets. The data confirms that the RX 9070 is the limiting factor at 4K, while the 12400F has ample headroom at lower resolutions.

CPU Role

The Intel Core i5-12400F is a 6-core, 12-thread processor based on 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, which is essential for the high frame rates seen in Pc Building Simulator. The CPU's cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. In synthetic benchmarks, the CPU scores 16518 in Cinebench R23 multicore and 2332 in single-core, while its average benchmark score is 19221. The single-core performance is particularly relevant for Pc Building Simulator, which is a simulation title that often relies on single-threaded physics and UI calculations. The boost clock of 4.40 GHz allows the CPU to handle these tasks quickly, and the data supports this: at 1080p Low, the combo reaches 348.4 FPS, which is only possible if the CPU can feed the GPU at that rate. The 12400F's 12 threads also help with background tasks and multitasking, but the game itself does not appear to be heavily multi-threaded, as the scaling from 1080p to 4K is dominated by GPU load. The CPU's 65 W TDP and support for DDR4 and DDR5 memory make it a flexible choice, but the benchmark results show it is not a top-tier performer, ranking in the 77th percentile. In the context of this combo, the CPU provides enough power to avoid bottlenecking the RX 9070 at 1080p and 1440p, but at 4K the GPU becomes the clear limiting factor, as evidenced by the identical High and Ultra frame rates.
