Pc Building Simulator

The AMD Ryzen 5 8400F and Intel Arc B580 combination delivers a surprisingly strong performance profile in Pc Building Simulator, a simulation title that clearly favors high frame rates over raw graphical fidelity. Benchmark results show this pairing is capable of handling the game at maximum settings at both 1080p and 1440p, while 4K requires a compromise on visual quality to maintain smooth gameplay. The data indicates a system that scales predictably across resolutions, with the CPU providing ample headroom for the GPU to stretch its legs at lower resolutions.

Best Settings per Resolution

At 1920x1080, the AMD Ryzen 5 8400F and Intel Arc B580 combo achieves a 102.1 average FPS at Ultra settings. This is the most demanding preset available, and it clears the 60 FPS playable threshold with a significant margin. Low settings push the average to 217.1 FPS, but there is no need to drop below Ultra when the game already runs this smoothly. The 110.1 FPS average at High settings shows that even the second-highest preset is far beyond what is needed for a comfortable experience, but the 102.1 FPS at Ultra is the definitive choice for maximum visual fidelity without sacrificing performance.

Moving to 2560x1440, the same Ultra preset remains viable, producing a 67.9 average FPS. This is the best settings choice for this resolution because it stays above the 60 FPS threshold while delivering the highest visual quality. The gap between Ultra and High is relatively small, with High averaging 70.2 FPS, but the 2.3 FPS difference is worth accepting for the improved detail. Medium settings hit 98.1 FPS and Low reaches 137.7 FPS, but these are unnecessary compromises given that Ultra already meets the playability standard.

At 3840x2160, the situation changes dramatically. Ultra settings drop to a 34.4 average FPS, which is unplayable. High settings fare slightly better at 36.9 FPS, and Medium produces 47.6 FPS — all below the 60 FPS target. The only viable option is Low settings, which achieve a 73.2 average FPS. This is the most demanding preset that clears the 60 FPS bar at 4K, and it does so with enough headroom to keep gameplay fluid. Pushing to Medium would cut frame rates by more than a third, so Low is the clear recommendation for 4K displays.

CPU and GPU Roles

The data reveals a clear division of labor between the AMD Ryzen 5 8400F and the Intel Arc B580 across resolutions. At 1080p, the CPU is the dominant factor. The 217.1 FPS average at Low settings shows that the processor can feed frames far faster than the GPU can render them at higher presets. The scaling from Low to Ultra at 1080p is a 53% drop in frame rate (217.1 to 102.1), which indicates that the GPU becomes the bottleneck as settings increase. The Ryzen 5 8400F's 6 cores and 12 threads, boosted by its Zen 4 architecture, provide enough single-thread performance to keep up with the Arc B580 at this resolution.

At 1440p, the balance shifts toward the GPU. The 137.7 FPS at Low settings drops to 67.9 FPS at Ultra, a 51% reduction that mirrors the 1080p pattern but at lower absolute numbers. The GPU is now the primary constraint, as the higher pixel count demands more from the Arc B580's 13.67 TFLOPS of raw compute. The CPU still has headroom, but it is no longer the limiting factor. This is evident in the fact that the Ryzen 5 8400F's multi-threaded performance, which ranks in the 77th percentile among all CPUs, is more than sufficient for the simulation's logic.

At 4K, the GPU is overwhelmingly the bottleneck. The Arc B580's 12 GB of GDDR6 memory and 456.0 GB/s bandwidth are taxed heavily by the 3840x2160 resolution. The frame rate at Low settings (73.2 FPS) is less than half of the 1080p Low result (217.1 FPS), showing that the GPU's fill rate and memory bandwidth are the limiting factors. The CPU's role diminishes further, as the Ryzen 5 8400F is barely challenged by the game's workload at this resolution. The scaling between 1080p and 4K at Low settings — a 66% drop in FPS — is almost entirely attributable to the GPU's inability to keep up with pixel throughput.

Measured FPS Breakdown

The full measured FPS table shows a consistent pattern across all three resolutions. At 1920x1080, the average frame rates are 217.1 on Low, 152.8 on Medium, 110.1 on High, and 102.1 on Ultra. The jump from Low to Medium is a 30% reduction, while the step from High to Ultra is a modest 7% drop. This suggests that the Ultra preset adds visual effects that are relatively inexpensive to render, making it a worthwhile upgrade over High.

At 2560x1440, the results are 137.7 on Low, 98.1 on Medium, 70.2 on High, and 67.9 on Ultra. The gap between High and Ultra narrows to just 3%, indicating that the Ultra preset at this resolution is nearly identical in cost to High. The transition from Low to Medium is a 29% reduction, consistent with the 1080p pattern.

At 3840x2160, the numbers are 73.2 on Low, 47.6 on Medium, 36.9 on High, and 34.4 on Ultra. Here, the cost of each preset tier is more pronounced. Moving from Low to Medium cuts performance by 35%, and the step from Medium to High is another 23% reduction. Ultra is only 7% slower than High, which shows that the Ultra preset's additional features are almost negligible at 4K — the resolution itself is the primary performance killer.

Min and max FPS values are not available in the data, so the analysis relies on averages. However, the consistency of the scaling across resolutions suggests stable frame delivery without major dips, particularly at 1080p and 1440p where the averages are well above the 60 FPS threshold.

Similar Performance Alternatives

The AMD Ryzen 5 8400F has nearest rivals that would behave nearly identically in Pc Building Simulator. The AMD Ryzen 5 7500F is the closest match, with an average benchmark score of 24964 versus the 8400F's 25005, a delta of just 0.2%. This means swapping to the 7500F would produce virtually identical frame rates in this game. The Intel Core i7-11850H and Intel Core i7-13620H are also within 0.3-0.4% of the 8400F's average score, making them equally viable alternatives if you happen to have one of those mobile processors in a desktop configuration. The AMD EPYC 9474F is slightly faster at 25103 (a -0.4% delta, meaning the 8400F is actually 0.4% ahead), but it is an enterprise part that would be an odd choice for gaming.

On the GPU side, the Intel Arc B580's nearest rivals are more varied. The AMD Radeon RX 580 2048SP scores 23061, which is 0.2% higher than the B580's 23021 — a negligible difference. The NVIDIA GeForce RTX 2080 scores 22895, putting it 0.6% behind the B580, while the NVIDIA GeForce RTX 3080 scores 23172, which is 0.7% ahead. The NVIDIA P106-100 at 23249 is 1% faster. In practical terms, all four of these GPUs would deliver frame rates within a couple of FPS of the B580 in Pc Building Simulator. The RTX 3080 would be the strongest performer of the group, but the differences are so small that they would be imperceptible in actual gameplay.

The Verdict

This PC can absolutely run Pc Building Simulator, with clear guidance from the verdict data. At 1920x1080, every preset from Low to Ultra clears the 60 FPS threshold, with Ultra averaging 102.1 FPS. This is the ideal resolution for this combo, offering maximum settings with more than 40 FPS of headroom. At 2560x1440, all four presets also clear 60 FPS, with Ultra averaging 67.9 FPS. This makes 1440p a fully viable option, although the headroom is tighter than at 1080p — a 7.9 FPS margin means that demanding scenes could occasionally dip closer to the threshold. At 3840x2160, only Low settings are playable, averaging 73.2 FPS. Medium (47.6 FPS), High (36.9 FPS), and Ultra (34.4 FPS) all fall short of the 60 FPS target and should be avoided.

In summary, the AMD Ryzen 5 8400F and Intel Arc B580 deliver a playable experience at 1080p and 1440p with Ultra settings, and at 4K only with Low settings. For a simulation game that emphasizes system management over fast-paced action, the 4K Low experience at 73.2 FPS is still smooth and perfectly enjoyable, but users with 4K displays should be prepared for reduced visual fidelity.

How This Combo Ranks

Within the benchmark database, this specific CPU-GPU combination ranks 2797 out of 3723 tested combos for Pc Building Simulator. This places it in the 25th percentile of all tested systems, meaning roughly three-quarters of all combinations tested perform better in this game. Given that the game is not particularly demanding, this ranking reflects the mid-range positioning of both components rather than any specific weakness. The Ryzen 5 8400F's 77th percentile ranking among all CPUs and the Arc B580's 68th percentile among all GPUs indicate that both parts are above-average performers individually, but the combination does not reach the upper echelon of gaming systems.

The rank suggests that while this combo is perfectly capable of running the game well — as shown by the 1080p and 1440p Ultra results — there are many faster systems available. For a simulation title with modest requirements, this ranking is acceptable, but users looking for the absolute highest frame rates might consider higher-tier components. The data shows that the 8400F and B580 sit in a comfortable mid-range sweet spot, delivering solid performance without the premium price tag of top-end hardware.
