Pc Building Simulator

The AMD Ryzen 5 8400F is a 6-core, 12-thread desktop processor built on the Zen 4 architecture and manufactured on TSMC's 4 nm process. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, drawing a 65 W TDP and fitting into the AMD Socket AM5 platform. This CPU is part of the 8000 series and carries the codename Phoenix. Its cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and a shared 16 MB of L3 cache. The processor supports DDR5 memory through a dual-channel interface, providing a memory bandwidth of 83.2 GB/s, and it offers PCIe Gen 4 with 20 lanes from the CPU. In synthetic benchmarks, the 8400F demonstrates solid multi-threaded capability, scoring 20,851 in Cinebench R23 multi-core and 2,943 in the single-core test, with a PassMark multithread score of 24,530 and a single-thread score of 3,684. Its average benchmark score of 25,064 places it in the 82nd percentile among all CPUs, indicating strong overall performance for its class.

For a simulation title like Pc Building Simulator, the CPU's multi-threaded performance is often more relevant than in fast-paced shooters, as the game logic and asset management can leverage multiple cores. The 8400F's 12 threads provide ample parallel processing headroom. When compared to its nearest rivals, the Ryzen 5 8400F is virtually tied with the AMD Ryzen 7 2700X, with a delta of 0%. It is also within 0.1% of the AMD Ryzen AI 5 PRO 340 and 0.2% of the AMD EPYC 9474F, while being 0.3% ahead of the AMD Ryzen 5 7500F. These negligible percentage differences suggest that in CPU-bound scenarios, the 8400F will perform on par with these alternatives, and the choice between them would come down to other platform features rather than raw compute power. The data indicates that the 8400F is a capable processor that should not be the primary bottleneck at lower resolutions in this game.

GPU Role

The Intel Arc B580 is built on the Xe2-HPG architecture, codenamed Battlemage, and is manufactured on a 5 nm process by TSMC. It features 2,560 shading units, 160 TMUs, and 80 ROPs, alongside 20 ray tracing cores. The GPU operates at a base and boost clock of 2670 MHz, with memory running at 2375 MHz (19 Gbps effective). It is equipped with 12 GB of GDDR6 memory on a 192-bit bus, yielding a memory bandwidth of 456.0 GB/s. The card's compute capabilities include 13.67 TFLOPS of FP32 performance and 27.34 TFLOPS of FP16 (2:1). Its 190 W TDP requires a dual-slot cooler and a single 8-pin power connector, with a suggested PSU of 450 W. The Arc B580 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and connects via a PCIe 4.0 x8 interface.

In benchmark tests, the Arc B580 achieves a PassMark G3D score of 15,748 and a Geekbench Vulkan score of 109,672, with a 3DMark Steel Nomad DX12 score of 3,068. Its average benchmark score of 23,021 places it in the 66th percentile of all GPUs. The nearest rivals show a tight grouping: the AMD Radeon 760M is 0.1% slower, the NVIDIA P106-100 is 0.3% slower, the NVIDIA GeForce RTX 4060 is 0.7% faster, and the NVIDIA GeForce RTX 4060 Mobile is 1.3% slower. This places the Arc B580 squarely in the performance tier of an RTX 4060 desktop, though the margin is small. For Pc Building Simulator, a game that is not typically graphically demanding, the Arc B580's 12 GB VRAM and 456.0 GB/s bandwidth are more than sufficient to handle high-resolution textures and effects without memory pressure, allowing the GPU to focus on rendering the simulation interface and 3D models.

Resolution Scaling

The measured FPS data reveals a clear scaling pattern across resolutions and settings, highlighting the balance between CPU and GPU loads. At 1080p with Low settings, the combo achieves an average of 217.1 FPS, which is exceptionally high and indicates that the CPU and GPU are both operating well below their limits. Moving to Medium settings at 1080p reduces the average to 152.8 FPS, a drop of 64.3 FPS, while High settings yield 110.1 FPS and Ultra settings drop further to 102.1 FPS. The progression from Low to Ultra at 1080p shows a total reduction of 115 FPS, or about 53%, which suggests that the GPU is becoming more involved as graphical fidelity increases, but the CPU still has ample headroom given the high absolute frame rates.

At 1440p, the scaling continues. Low settings produce an average of 137.7 FPS, which is a 36.6% drop from the 1080p Low figure, indicating a shift toward GPU limitation. Medium settings at 1440p yield 98.1 FPS, High settings 70.2 FPS, and Ultra 67.9 FPS. The drop from 1080p High to 1440p High is 39.9 FPS, or 36.3%, which is consistent with a growing GPU bottleneck as pixel count increases. At 4K, the GPU becomes the clear limiting factor. Low settings at 4K average 73.2 FPS, which is still playable but represents a 66.3% decrease from the 1080p Low result. Medium settings at 4K drop to 47.6 FPS, High settings to 36.9 FPS, and Ultra to 34.4 FPS. The transition from 1080p High to 4K High is a 73.2 FPS reduction, or 66.5%, showing that the Arc B580's rendering load scales significantly with resolution. The data suggests that at 1080p, the system is CPU-bound with very high frame rates, while at 4K, the GPU is the primary constraint, especially at higher settings where the frame rate falls below the 60 FPS threshold.

How This Combo Ranks

The combination of the AMD Ryzen 5 8400F and Intel Arc B580 is ranked 1,364 out of 1,769 tested combos in Pc Building Simulator. This places it in the lower half of the database, specifically around the 23rd percentile of all tested pairings. Given that the CPU and GPU each individually sit in the 82nd and 66th percentiles respectively, the combo's rank is lower than either component's standalone percentile, suggesting that the pairing may not be optimally balanced for this specific game, or that the game's performance characteristics do not heavily favor this particular combination of mid-range hardware. The rank indicates that there are 1,363 other combinations that deliver higher average frame rates in this title, which is expected given the vast number of high-end parts available. However, the measured FPS data shows that this combo is capable of smooth gameplay at 1080p and 1440p on most settings, with the 4K Ultra experience being the only scenario where frame rates dip to challenging levels. The data suggests that while the combo does not top the charts, it offers a viable mid-range experience, with the GPU becoming the primary limiter at higher resolutions as evidenced by the significant FPS drops from 1080p to 4K.
