Pc Building Simulator

The pairing of the AMD Ryzen 5 8400F with the AMD Radeon RX 580 produces a system that is firmly positioned in the lower quartile of tested combinations for Pc Building Simulator, ranking 3403rd out of 3723 combos. This is a configuration where the legacy Polaris GPU acts as the primary constraint, yet the data shows a surprisingly playable experience at lower resolutions, provided settings are managed carefully. The benchmark results indicate a system with a clear ceiling: it cannot maintain a 60 FPS average at 1440p or 4K on any preset, but it delivers a smooth 1080p experience at Medium settings, making it a viable entry-level option for this simulation title.

Resolution Scaling

The measured frame rates reveal a steep performance curve as resolution increases, a classic signature of a GPU-bound scenario. At 1080p with Low settings, the system achieves an average of 120 FPS, but this drops by exactly 50% to 60 FPS at High settings, and further to 57 FPS at Ultra. This demonstrates that even at the lowest resolution, the RX 580 is heavily taxed by the simulation's rendering load, as the difference between Low and Ultra presets is a substantial 63 FPS (from 120 down to 57).

Moving to 1440p, the scaling becomes more punishing. The Low preset average falls to 76 FPS, which is a 36.7% reduction from the 1080p Low figure. At High settings, the 1440p average of 38 FPS is nearly half the 60 FPS seen at 1080p, indicating that the GPU's fill rate and memory bandwidth are insufficient for the increased pixel count. The Medium preset at 1440p shows 54 FPS with a minimum of 46 FPS, suggesting occasional stutter in busier scenes, while Ultra drops to 36 FPS, which is below the threshold for comfortable play.

The 4K results are decisive in confirming the GPU bottleneck. At 3840x2160, the High preset averages just 20 FPS, and Ultra falls to 19 FPS—both figures are effectively unplayable. Even the Low preset at 4K only reaches 40 FPS, which is below the 60 FPS target. The frame rate scaling from 1080p to 4K is dramatic: the Low preset loses 80 FPS (from 120 to 40), and the High preset loses 40 FPS (from 60 to 20). This pattern indicates that the RX 580's 8 GB of GDDR5 memory and 256-bit bus, while adequate for 1080p, cannot handle the memory bandwidth demands of 4K rendering. The CPU, with its 6 cores and 12 threads, is not the limiting factor here; rather, the GPU's processing power is exhausted at higher resolutions.

Settings Recommendations

The ideal preset for this combo is Medium at 1080p, where the measured average of 85 FPS with a minimum of 72 FPS provides a solid, stutter-free experience. This is the only setting and resolution combination in the data that achieves both a high average and a minimum above 60 FPS, making it the clear recommendation for a smooth gameplay experience. The jump from Low to Medium at 1080p costs 35 FPS (from 120 to 85), but the visual fidelity improvement is worth it, as the system still maintains headroom above the 60 FPS target.

For users with a 1440p monitor, the Medium preset at 54 FPS is the most balanced choice, though the 46 FPS minimum indicates potential dips during complex scenes. The High preset at 1440p (38 FPS) and Ultra (36 FPS) are both too demanding, while Low (76 FPS) sacrifices too much visual quality for a marginal gain. At 4K, no preset is recommended for active play; the best result is Low at 40 FPS, which is still below the 60 FPS threshold and would require significant compromises in visual fidelity. The data strongly suggests that this system is best suited for 1080p gaming, with Medium being the sweet spot that balances performance and visual quality.

CPU Role

The AMD Ryzen 5 8400F is a Zen 4 architecture processor with 6 cores and 12 threads, running at a base clock of 4.20 GHz and a boost clock of 4.70 GHz. Its benchmark scores are respectable for a mainstream desktop chip, with a Cinebench R23 multi-core score of 20851 and a single-core score of 2943, placing it in the 77th percentile of all CPUs. The nearest rival data shows it is virtually tied with the AMD Ryzen 5 7500F (0.2% faster) and the Intel Core i7-13620H (0.4% faster), while being 0.4% slower than the AMD EPYC 9474F. This indicates that the CPU is a modern, capable part that should not bottleneck most games.

In this specific game, however, the CPU's role is secondary to the GPU. The measured frame rates show a clear GPU limitation, as evidenced by the significant FPS drops when increasing resolution. The 3DMark multi-threaded scores, ranging from 1874 for 2 threads to 6165 for max threads, suggest the processor has ample headroom for simulation tasks. The 65W TDP and DDR5 memory support (with 83.2 GB/s bandwidth) provide a solid foundation, but the game's performance is capped by the RX 580's output. The fact that the 1080p Low preset hits 120 FPS while 4K Low drops to 40 FPS is a textbook example of a GPU bottleneck, where the CPU is waiting on the graphics card to render frames. The CPU's high single-thread performance (PassMark single-thread score of 3685) ensures it can feed the GPU efficiently, but it cannot compensate for the GPU's architectural limitations at higher resolutions.

How This Combo Ranks

This combination of a Ryzen 5 8400F and RX 580 ranks 3403rd out of 3723 tested combos for Pc Building Simulator, placing it in the bottom 8.6% of all configurations. This low ranking is primarily due to the GPU's age and performance class, as the RX 580 sits in the 53rd percentile of all GPUs, while the CPU is in the 77th percentile. The pairing is inherently unbalanced, as the modern CPU is held back by the seven-year-old GPU architecture.

The GPU's nearest rivals illustrate its position: the RX 580 is 0.1% slower than the NVIDIA GeForce RTX 3050 Ti Mobile, 0.4% slower than the GTX 1660 SUPER, and 0.5% faster than the AMD Radeon 740M. These are all mid-range parts, and the RX 580's 6.175 TFLOPS FP32 performance and 256.0 GB/s memory bandwidth are modest by today's standards. The combo's rank suggests that users would need to significantly lower expectations compared to more modern pairings, but the 1080p Medium result shows it is not a completely obsolete setup. The data indicates that this combo is best suited for older or less demanding titles, or for users who prioritize CPU performance for non-gaming tasks and accept lower graphical settings in games.

GPU Role

The AMD Radeon RX 580 is the primary determinant of this system's gaming performance. Built on the GCN 4.0 architecture with a Polaris 20 chip, it features 2304 shading units, 144 texture mapping units, and 32 ROPs. Its base clock is 1257 MHz with a boost clock of 1340 MHz, and it has 8 GB of GDDR5 memory on a 256-bit bus, delivering 256.0 GB/s of bandwidth. These specifications are reflected in its benchmark performance, where it scores 8813 in PassMark G3D and 37453 in Geekbench OpenCL, placing it in the 53rd percentile of all GPUs.

The GPU's limitations are evident in the measured FPS data. At 1080p, it can achieve 120 FPS on Low, but this drops to 85 FPS on Medium and 60 FPS on High, showing that the chip's processing power is quickly saturated as settings increase. The 4K results are particularly telling, with the Ultra preset at 19 FPS being essentially a slideshow. The RX 580's nearest rival, the GTX 1660 SUPER, is only 0.4% faster, which explains why this GPU is categorized as an entry-level solution in 2025. The 185W TDP and dual-slot design are consistent with its 2017 release, and its end-of-life production status means no further driver optimizations are likely. For this game, the GPU's 8 GB VRAM is sufficient for 1080p textures, but the lack of modern features like hardware ray tracing (0 RT cores) and the older GCN architecture limit its efficiency in newer titles.
