A motherboard chipset is a group of chips installed on a computer motherboard that coordinates and controls the communication and data transfer of the various components on the motherboard. The motherboard chipset usually consists of two parts: a north bridge and a south bridge. The North bridge handles communication between high-speed components such as processors, memory, and graphics, while the South bridge handles communication between low-speed components such as hard drives, USB interfaces, and audio interfaces. The choice of motherboard chipset has an important impact on the performance and scalability of the computer, and different chipsets support different processors and interface standards, so the performance and compatibility of the chipset need to be considered when choosing the motherboard.
