Pc Building Simulator

The Intel Core i5-9400 paired with the AMD Radeon RX 570 is a mid-range combination for Pc Building Simulator. Measured frame rates across four presets and three resolutions show a system that can handle 1080p comfortably, but struggles at 4K. The combo ranks 1682 out of 1769 tested configurations, placing it in the lower third of all tested hardware pairings for this game.

Settings Recommendations

The measured FPS data provides a clear picture of which preset to choose at each resolution. At 1920x1080, the Medium preset delivers 75.7 FPS, which is above the 60 FPS threshold commonly considered smooth. High and Ultra both fall below that mark, at 54.5 and 53.4 FPS respectively. Low reaches 109.9 FPS, but the visual quality trade-off is unnecessary when Medium already provides a comfortable margin. For 1080p, Medium is the best balance of fluidity and fidelity.

At 2560x1440, the situation changes. Only the Low preset stays above 60 FPS, with 67.3 FPS. Medium drops to 47 FPS, High to 36.1, and Ultra to 33.9. If a 60 FPS target is non-negotiable, Low is the only option. For users who can tolerate slightly lower frame rates, Medium at 47 FPS is still playable, but the step down from Low to Medium costs roughly 30% of the frame rate. High and Ultra are not recommended at 1440p, as they fall below 40 FPS.

At 3840x2160, none of the presets reach 60 FPS. Low is the only preset above 30 FPS, at 34.6. Medium manages 26.1, High 20.2, and Ultra 16.1. For 4K, Low is the only viable choice, and even then the experience will be stuttery. The data suggests that 4K is not a practical target for this combination, regardless of settings.

Notably, at 1080p, High and Ultra are nearly identical in performance (54.5 vs 53.4 FPS). The 1.1 FPS difference is negligible, so High is the more efficient choice if you want the highest visual quality without sacrificing frame rate. The same pattern holds at 1440p, where High and Ultra differ by only 2.2 FPS. In both cases, Ultra offers no meaningful performance advantage, so High is the better pick when you want to push quality without paying a large FPS penalty.

GPU Role

The AMD Radeon RX 570 is built on the Polaris 20 chip with GCN 4.0 architecture. It has 4 GB of GDDR5 memory on a 256-bit bus, providing 224.0 GB/s of bandwidth. The base clock is 1168 MHz, with a boost clock of 1244 MHz, and memory runs at 1750 MHz (7 Gbps effective). The GPU has 2048 shading units, 128 texture mapping units, and 32 ROPs. Its pixel rate is 39.81 GPixel/s, texture rate is 159.2 GTexel/s, and FP32 performance is 5.095 TFLOPS.

In synthetic benchmarks, the RX 570 scores 880 in 3DMark Steel Nomad DX12, 44915 in Geekbench Metal, 32084 in Geekbench OpenCL, and 42752 in Geekbench Vulkan. Its average benchmark score is 30158, placing it in the 74th percentile of all GPUs. The nearest rival is the NVIDIA GeForce RTX 5060, which has an average score of 30109; the RX 570 is 0.2% faster. Other close rivals include the AMD Radeon RX 7700 XT (30097, 0.2% faster), the NVIDIA Tesla M60 (29969, 0.6% faster), and the NVIDIA GeForce RTX 5070 Mobile (29928, 0.8% faster). These deltas are tiny, indicating that the RX 570 sits in a performance cluster where synthetic scores are nearly identical.

In Pc Building Simulator, the GPU's role is evident from the FPS scaling. At 1080p Low, the system reaches 109.9 FPS, which suggests the GPU is not the limiting factor at that resolution and preset. However, as resolution increases, frame rates drop sharply. The 4 GB VRAM and 224 GB/s bandwidth are likely the constraints at 4K, where even Low only manages 34.6 FPS. The game is a simulation, and while it may not be graphically intense, the data shows that the RX 570's memory subsystem becomes a bottleneck at higher resolutions. The launch MSRP of the RX 570 was 169 USD.

Resolution Scaling

The FPS drop from 1080p to 1440p to 4K is not linear, and the pattern reveals where the system becomes GPU-bound. At Low settings, 1080p delivers 109.9 FPS, 1440p drops to 67.3 (a 38.8% reduction), and 4K falls to 34.6 (a 48.6% reduction from 1440p). At Medium, the progression is 75.7 → 47.0 (37.9% drop) → 26.1 (44.5% drop). High goes from 54.5 → 36.1 (33.8% drop) → 20.2 (44.0% drop). Ultra starts at 53.4, falls to 33.9 (36.5% drop), then to 16.1 (52.5% drop).

The percentage drop from 1440p to 4K is consistently larger than the drop from 1080p to 1440p, especially at Ultra where the 4K figure is less than half of the 1440p value. This steepening curve indicates that the GPU's memory bandwidth and fill rate are being saturated as pixel count increases. The RX 570's 224 GB/s bandwidth and 4 GB VRAM are insufficient for 4K, even at Low settings. At 1080p, the system has enough headroom to reach high frame rates, but the GPU becomes the clear limiting factor as resolution climbs.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor based on Coffee Lake, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. It has a 65 W TDP and 9 MB of shared L3 cache. In Cinebench R15, it scores 803 multicore and 113 single-core; in R20, 3346 multicore and 472 single-core; in R23, 7969 multicore and 1125 single-core. Its average benchmark score is 2305, placing it in the 50th percentile of all CPUs. The nearest rivals are the Intel Core i3-10305 (2300, 0.2% faster), the Intel Core i3-1125G4 (2299, 0.2% faster), the Intel Xeon E-2134 (2295, 0.4% faster), and the Intel Core i7-8809G (2319, 0.6% slower). The i5-9400 is slightly faster than the first three and slightly slower than the i7-8809G.

In Pc Building Simulator, the CPU does not appear to be a bottleneck. At 1080p Low, the system reaches 109.9 FPS, which is well above typical display refresh rates. Even at 1080p Ultra, the frame rate is 53.4, still playable. The game is a simulation, and while it may involve complex logic, the i5-9400's six cores and 4.10 GHz boost clock provide sufficient processing power. The single-core score of 1125 in Cinebench R23 suggests that the CPU can handle the game's main thread without limiting the GPU. The resolution scaling data confirms this: if the CPU were the bottleneck, frame rates would remain flat across resolutions, but they drop sharply, indicating the GPU is the limiting component. For this title, the i5-9400 is a capable partner for the RX 570, offering enough headroom to let the GPU work at its full potential at 1080p and 1440p.
