Pc Building Simulator

The Intel Core i5-12400F paired with the AMD Radeon RX 570 delivers a playable but firmly entry-level experience in Pc Building Simulator, with the data showing that the combination ranks in the bottom 6% of tested systems. The benchmark results indicate that while the CPU offers robust multi-threaded performance for a simulation title, the GPU becomes the definitive bottleneck at higher resolutions and settings, capping frame rates well below what the processor can feed.

CPU Role

The Intel Core i5-12400F provides a strong foundation for this simulation game, with its 6 cores and 12 threads operating at a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This Alder Lake-S architecture processor, built on Intel's 10 nm process, demonstrates solid computational headroom in synthetic tests, scoring 16,518 in Cinebench R23 multi-core and 2,332 in single-core. Its average benchmark score of 19,221 places it at the 77th percentile of all CPUs, and it trades blows with the Intel Core i7-8700K (0.1% faster) and AMD Ryzen 5 7533HS (0.7% slower).

In Pc Building Simulator, which simulates system assembly and benchmarking rather than demanding physics or AI, the CPU's role is less about raw frame generation and more about maintaining consistent simulation logic. The data shows that when the GPU is not the limiting factor, the i5-12400F's 18 MB of shared L3 cache and dual-channel memory support (DDR4, DDR5) keep the simulation running smoothly. However, the measured frame rates across all resolutions and settings rarely exceed the 105.6 FPS ceiling seen at 1080p Low, suggesting that even at the lowest graphical load, the 12-thread processor is sufficient but not overstretched. The CPU's 3DMark scores—5,895 for 16 threads and 5,912 for max threads—confirm that multi-threaded workloads are handled competently, but the game's frame rate is ultimately dictated by the graphics card in most scenarios.

GPU Role

The AMD Radeon RX 570, built on the GCN 4.0 architecture with the Polaris 20 chip, is the clear performance limiter in this pairing. With 4 GB of GDDR5 memory on a 256-bit bus delivering 224.0 GB/s bandwidth, the GPU operates at a base clock of 1168 MHz and a boost clock of 1244 MHz. Its 2,048 shading units and 32 ROPs provide a raw compute throughput of 5.095 TFLOPS, which places it at the 74th percentile of all GPUs. Interestingly, its average benchmark score of 30,158 puts it within 0.2% of the NVIDIA GeForce RTX 5060 and 0.2% of the AMD Radeon RX 7700 XT in aggregate synthetic tests, though this reflects a specific benchmark set rather than gaming performance.

In Pc Building Simulator, the RX 570's 4 GB VRAM becomes a critical constraint at higher resolutions. The measured FPS data shows a steep drop when moving from 1080p to 4K, particularly at High and Ultra settings where the frame rate falls below 20 FPS. The GPU's 150 W TDP and 224.0 GB/s bandwidth are adequate for the simulation's moderate graphical demands, but the 4 GB frame buffer is insufficient for 4K Ultra, where the average FPS of 14.5 indicates the card is overwhelmed. The GPU's Vulkan score of 42,752 and DirectX 12 support (12_0) suggest it can handle modern APIs, but the data clearly shows that this card is best suited for 1080p gaming with this CPU.

Settings Recommendations

The measured FPS data points to 1080p Medium as the optimal balance for this combination, delivering 78 FPS average. This setting provides a smooth, responsive experience while maintaining visual fidelity, and it represents a 47.3% improvement over High settings (53 FPS) without the graphical compromises of Low (105.6 FPS). At 1440p, the data shows that Medium is also the best choice, yielding 47 FPS, which is playable but not ideal for fast-paced interaction. However, 1440p Ultra (35.6 FPS) and 4K Medium (26.2 FPS) fall below the 30 FPS threshold for comfortable playability, making them less recommended.

For users prioritizing frame rate over visuals, 1080p Low at 105.6 FPS is the only setting that fully utilizes the CPU's potential, but the visual downgrade is significant. The data suggests that the RX 570's 4 GB VRAM is the limiting factor at High and Ultra presets, as the frame rate drops disproportionately compared to the step from Low to Medium. In Pc Building Simulator, where the primary activity is navigating menus and observing benchmark results, 1080p Medium offers the best experience per the measured rows, providing a stable 78 FPS that avoids the stutter associated with lower frame rates.

How This Combo Ranks

This specific combination of Intel Core i5-12400F and AMD Radeon RX 570 ranks 1,667 out of 1,769 tested combos in Pc Building Simulator, placing it in the bottom 5.8% of all systems. This low ranking underscores that while each component is individually competent—the CPU at the 77th percentile and GPU at the 74th percentile—their pairing is suboptimal for this game. The data indicates that the RX 570 holds back the i5-12400F significantly, as evidenced by the fact that the CPU's nearest rivals (Intel Core i7-8700K, AMD Ryzen 5 7533HS) would likely achieve higher frame rates with a more capable GPU.

The rank of 1,667 out of 1,769 suggests that the vast majority of tested combos outperform this pairing, likely due to more balanced component selection or newer GPU architectures. The RX 570's end-of-life production status and 2017 release date (compared to the CPU's 2022 release) create a generational gap that manifests in the frame rate data. Users should interpret this ranking as a warning that while the system is functional, it is far from optimal for Pc Building Simulator, and the GPU is the primary bottleneck preventing higher performance.

Resolution Scaling

The measured FPS data reveals a consistent and severe drop as resolution increases from 1080p to 4K, confirming that the GPU is the limiting component. At Medium settings, the average frame rate falls from 78 FPS at 1080p to 47 FPS at 1440p (a 39.7% drop) and then to 26.2 FPS at 4K (a 66.4% drop from 1080p). This pattern is even more pronounced at High settings, where the frame rate drops from 53 FPS at 1080p to 36.3 FPS at 1440p (a 31.5% drop) and then to 19.7 FPS at 4K (a 62.8% drop from 1080p).

The resolution scaling behavior indicates that the RX 570's 4 GB VRAM and 224.0 GB/s bandwidth are insufficient for 4K rendering, as the frame rate falls below 20 FPS at High and below 30 FPS at Medium. The CPU's performance is not the limiting factor here, as the i5-12400F's multi-threaded scores (19,433 in PassMark multithread) suggest it could handle higher frame rates if the GPU were faster. The data shows that 1080p is the only resolution where this combo achieves consistently playable frame rates across all settings, while 1440p is marginal and 4K is only viable at Low settings (37.7 FPS).

Measured FPS Breakdown

At 1920x1080, the data shows a clear progression: Low settings produce 105.6 FPS, Medium drops to 78 FPS, High falls to 53 FPS, and Ultra yields 55 FPS. The anomaly where Ultra (55 FPS) is slightly higher than High (53 FPS) suggests measurement variance, but both are in the same range. At 2560x1440, the frame rates are 69.8 FPS (Low), 47 FPS (Medium), 36.3 FPS (High), and 35.6 FPS (Ultra). The gap between Medium and High narrows at 1440p, indicating that VRAM constraints begin to flatten the performance curve. At 3840x2160, the results are 37.7 FPS (Low), 26.2 FPS (Medium), 19.7 FPS (High), and 14.5 FPS (Ultra). The 4K Low setting is the only 4K configuration above 30 FPS, and it still represents a 64.3% drop from the 1080p Low result.

The Ultra settings at 1080p (55 FPS) and 1440p (35.6 FPS) show that the RX 570 can handle the highest preset at lower resolutions, but the 4K Ultra result of 14.5 FPS is effectively unplayable. The data shows that the step from Medium to High at 1080p costs 25 FPS, while the step from High to Ultra costs only 2 FPS, suggesting that the High preset is a poor value compared to Medium or Ultra.
