The difference between the south bridge chip and the North bridge chip is that the position and function on the motherboard are different, and the development direction is different.
The north bridge chip is the closest chip to the CPU on the motherboard, with the CPU socket as the north, a chip that plays a connection role near the CPU socket is called \"North bridge chip; The South Bridge chip (South Bridge) is an important part of the motherboard chipset, generally located on the motherboard far from the CPU slot below, in front of the PCI, that is, the front side of the main box.
North bridge is mainly responsible for the data exchange between CPU and memory, and mainly controls high-speed devices such as CPU memory graphics cards; The South bridge is mainly responsible for the control of some peripheral interfaces such as I\/O interfaces, the control of IDE devices and additional functions.
The data processing capacity of the North bridge chip is very large, and the heat output is also increasing, so the current North bridge chip is covered with heat sinks to strengthen the heat dissipation of the North bridge chip, and some of the North bridge chip of the motherboard will also cooperate with the fan for heat dissipation; The development direction of the Southbridge chip is mainly to integrate more functions, such as network cards, RAID, IEEE1394, and even WI-FI wireless networks. : - Northbridge chip
