North Bridge chip and South Bridge chip, also known as North bridge and South Bridge, are the two core chips that make up the computer motherboard. Their functions are different, mainly with the following differences:
1. Location: The North bridge chip is a chip located between the CPU and RAM on the motherboard, and its main function is to handle high-speed data transmission such as memory and graphics\/video cards; The Southbridge chip is a chip located on the lower part of the motherboard that handles the slower input and output of various I\/O devices.
2. Function: The North bridge chip usually includes the North Bridge bus, memory controller, graphics chip controller, etc., which is the core control chip of the computer system, responsible for managing and coordinating the communication between various components; The South bridge chip is the implementation of some low-speed devices, such as USB, SATA, network cards, etc.
3. Efficiency: The transmission speed of the South bridge chip is slow, while the North bridge chip supports high-speed memory, graphics devices and other components, so it has higher performance and processing efficiency.
In general, the north bridge chip and the south bridge chip each play different important roles in the computer motherboard, and cooperate with the function of the entire computer system.
differ in
One is the location. The north bridge chip is installed next to the cpu, while the south bridge chip is installed next to the hard disk.
Second, the function is different. The North bridge chip plays a decisive role in the computer, while the South Bridge chip plays a general role.
