1. Different locations
< br >
The South bridge chip is located in a position near the IDE interface or SATA interface of its hard disk, which is not covered, and there are words such as VIA or SIS or INTER on the chip, indicating the manufacturer of the South bridge chip, and the chip that is closer to the hard disk data line interface is the South Bridge chip.
< br >
The North bridge chip is located in a position near the CPU, which is generally covered with heat sinks, and the chip closer to the CPU is the North Bridge chip.

2. Different functions
< br >
Southbridge chips are responsible for communication between I\/O buses, such as PCI bus, USB, LAN, ATA, SATA, audio controllers, keyboard controllers, real-time clock controllers, advanced power management, etc. These technologies are generally relatively stable.
< br >
The Northbridge chip is responsible for the contact with the CPU and controls the memory AGP data transmission within the Northbridge, providing support for the type and main frequency of the CPU, the front-end bus frequency of the system, the type and maximum capacity of the memory, AGP slot, ECC error correction, etc. The integrated chipset's Northbridge chip also integrates the display core. The role of the North bridge chip is very obvious, and it plays a decisive role in the computer.

3. Different characteristics
< br >
Southbridge chip has the features of dual-chip design, integrated network, high quality audio, video card working bus and so on.
< br >
Because the North bridge chip plays this leading role, the heat is also very large, generally need to cover the heat sink, and some also add fan heat dissipation.

4. Different meanings
< br >
The Southbridge chip is an important part of the motherboard chipset and is responsible for the communication between the I\/O buses.
< br >
The North bridge chip is the most important component of the motherboard chipset that plays a dominant role, responsible for the connection with the CPU and controlling the memory.
The North bridge chip and the South Bridge chip are two different chips on the motherboard, and their functions and characteristics are also different. The Northbridge chip is usually located in the center of the motherboard and is responsible for connecting high-speed devices such as cpus, memory, graphics cards, etc. The Southbridge chip is usually located on the edge of the motherboard and is responsible for connecting low-speed devices, such as hard disks, USB interfaces, network cards, etc. In general, the North bridge chip is responsible for processing high-speed data, while the South bridge chip is responsible for processing low-speed data.
