CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor based on Coffee Lake architecture, built on Intel's 14 nm process. It operates at a base clock of 2.90 GHz and boosts up to 4.10 GHz, with a 65 W TDP and support for DDR4 memory in dual-channel configuration. The chip features 64 KB L1 cache per core, 256 KB L2 per core, and 9 MB shared L3 cache, with a memory bandwidth of 42.7 GB/s. These specifications place it at the 50th percentile among all CPUs, with an average benchmark score of 2305.

In Pc Building Simulator, the CPU's role is less about raw rendering and more about simulation logic, but the benchmark results reveal its limitations. The Cinebench R23 multicore score of 7969 and single-core score of 1125 indicate modest throughput, which is sufficient for the game's systems but not exceptional. The nearest CPU rivals show a tight cluster: the Core i3-10305 scores 2300 (0.2% faster), the Core i3-1125G4 scores 2299 (0.2% faster), and the Xeon E-2134 scores 2295 (0.4% faster). The Core i7-8809G leads at 2319, just 0.6% ahead.

The CPU's 6 threads are adequate for a simulation title, but the data shows that frame rates scale more with GPU settings than CPU frequency. At 1080p Low, the combo hits 217.5 FPS, which suggests the CPU can feed the GPU effectively at lower loads. However, at 4K Ultra, the frame rate collapses to 36.6 FPS, indicating that the GPU is the primary bottleneck. The CPU's 50th percentile ranking aligns with a mid-tier position; it is not a performance outlier but also not a weak link for this game's modest demands.

GPU Role

The Intel Arc B580 is built on the Xe2-HPG architecture (Battlemage generation) using TSMC's 5 nm process, with 19,600 million transistors on a 272 mm² die. It features 12 GB of GDDR6 memory on a 192-bit bus, delivering 456.0 GB/s bandwidth. The GPU runs at a base and boost clock of 2670 MHz, with memory at 2375 MHz (19 Gbps effective). It has 2560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores, achieving 13.67 TFLOPS FP32 and 213.6 GPixel/s pixel rate.

The Arc B580 holds a 66th percentile ranking among all GPUs, with an average benchmark score of 23021. Its nearest rivals are tightly grouped: the AMD Radeon 760M scores 22999 (0.1% slower), the NVIDIA P106-100 scores 22950 (0.3% slower), and the RTX 4060 Mobile scores 22729 (1.3% slower). The RTX 4060 desktop leads at 23181, just 0.7% faster. This cluster indicates the B580 is a solid mid-range performer, but its 12 GB VRAM and 192-bit bus are more than sufficient for Pc Building Simulator's modest textures.

The GPU's influence on frame rates is stark. At 1080p, dropping from Ultra (104.7 FPS) to Low (217.5 FPS) more than doubles performance, showing that the B580 scales well with reduced load. At 4K, the GPU is clearly the limiting factor: even Low settings only reach 68.5 FPS, while Ultra falls to 36.6 FPS. The 13.67 TFLOPS compute throughput handles the simulation's 2D and UI elements easily, but at 4K the pixel fill rate becomes insufficient for high presets.

Settings Recommendations

The measured FPS data provides a clear picture of which presets offer the best experience at each resolution. At 1920x1080, the High preset delivers 109.9 FPS, which is nearly identical to Ultra (104.7 FPS) but with a slight performance gain. Medium (153.9 FPS) and Low (217.5 FPS) both exceed 150 FPS, but High offers the best balance of visual quality and smoothness for most users. The difference between High and Ultra is only 5.2 FPS, so High is the recommended choice at 1080p.

At 2560x1440, the situation changes. High (68 FPS) and Ultra (65 FPS) are nearly identical, while Medium (95.5 FPS) provides a substantial 40% improvement over Ultra. Low hits 138.7 FPS, which is the only preset that fully saturates a 120Hz display. For 1440p, Medium is the optimal preset, as it maintains frame rates above 90 FPS while preserving more visual fidelity than Low. High offers no meaningful advantage over Ultra, so users should either stick with Medium or accept the 65 FPS floor of Ultra.

At 3840x2160, only Low (68.5 FPS) achieves playable frame rates above 60 FPS. Medium (47.8 FPS), High (37.6 FPS), and Ultra (36.6 FPS) all fall below 50 FPS, making them unsuitable for smooth gameplay. The Low preset is the only viable option at 4K, and even it hovers near the 60 FPS threshold. For users prioritizing visual quality at 4K, the data suggests reducing resolution to 1440p and using Medium, which yields 95.5 FPS, a 40% improvement over 4K Low.

How This Combo Ranks

The Intel Core i5-9400 + Intel Arc B580 combo ranks 1366 out of 1769 tested combinations in Pc Building Simulator, placing it in the lower 23% of all pairings. This rank is notable because the GPU alone sits at the 66th percentile among all GPUs, while the CPU sits at the 50th percentile. The combination's rank suggests that the CPU's modest single-thread performance (1125 in Cinebench R23 single-core) may be holding back the GPU in this simulation title, which likely relies on single-threaded logic for system assembly calculations.

The rank disparity is also evident when comparing frame rates across resolutions. The combo performs best at 1080p, where the GPU's 12 GB VRAM and 456.0 GB/s bandwidth are more than sufficient, and the CPU's 6 threads can keep up with the game's logic. At 4K, the combo falls to 36.6 FPS on Ultra, which is below the playable threshold, indicating that the GPU's 13.67 TFLOPS is insufficient for high-resolution rendering. The 1366 rank reflects this mixed performance: strong at lower resolutions but weak at higher ones.

Compared to other combos in the database, this pairing is not an outlier. The GPU's nearest rival, the RTX 4060, scores only 0.7% higher on average, yet the combo rank suggests that the CPU pairing plays a significant role. The Core i5-9400's 50th percentile CPU score positions it as an average processor, and when combined with a 66th percentile GPU, the overall result is a mid-tier build that excels at 1080p but struggles at 4K.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance. Low settings produce 217.5 FPS, Medium yields 153.9 FPS, High hits 109.9 FPS, and Ultra manages 104.7 FPS. The scaling from Ultra to Low is steep, with Low being 108% faster than Ultra. The gap between Medium and High is 44 FPS, while the gap between High and Ultra is just 5.2 FPS, showing diminishing returns at the higher presets.

At 2560x1440, frame rates drop significantly but remain playable. Low settings achieve 138.7 FPS, Medium reaches 95.5 FPS, High hits 68 FPS, and Ultra falls to 65 FPS. The scaling from Low to Medium is 43.2 FPS, while the transition from Medium to High is 27.5 FPS. High and Ultra are nearly identical, with only a 3 FPS difference, indicating that the Ultra preset adds little visual benefit at 1440p.

At 3840x2160, only Low settings (68.5 FPS) exceed the 60 FPS threshold. Medium drops to 47.8 FPS, High falls to 37.6 FPS, and Ultra bottoms out at 36.6 FPS. The scaling from Low to Medium is 20.7 FPS, and from Medium to High is 10.2 FPS, while High to Ultra is a marginal 1 FPS difference. The 4K data shows that the GPU's 213.6 GPixel/s pixel rate is insufficient for high-quality rendering at this resolution, with the Low preset being the only viable option for smooth gameplay.
