About This Architecture

PC System Architecture diagram illustrates a modern motherboard layout with four functional tiers: Processing (CPU and GPU), Memory (DDR5 DIMM slots 1-4), Storage (NVMe M.2 and SATA HDD), and I/O (USB 3.2 hub with peripherals and display output). The CPU serves as the central hub, connecting directly to GPU, all memory modules, storage devices, and USB controller, while the GPU handles display output via HDMI/DP and network connectivity. This hierarchical design demonstrates how component interconnection affects bandwidth allocation, thermal management, and upgrade potential for high-performance systems. Use this diagram to plan component compatibility, visualize data flow paths, or document your build specifications before purchasing hardware. The modular tier structure helps identify bottlenecks and optimization opportunities in your system design.
