Excuse me, what do the north and south bridges mean? What role do they play in the motherboard?

The North-South Bridge is already called before!

The northbridge and southbridge structures are widely used in almost all current PC motherboards. In the traditional north-south bridge structure, the north bridge (that is, a large chip on the motherboard near the CPU socket) is responsible for the connection with the CPU and controls the memory, AGP, and PCI interfaces, and the relevant data is transmitted within the north bridge. Minbashi is responsible for the control of the IO interface and IDE equipment. However, Intel began to abandon the structure of the north-south bridge from 810.

The HUB architecture structure of GMCH (AGP memory control center) + ICH (IO control center) is adopted. This makes the internal transmission speed speed up a lot, which represents the development direction of the motherboard chipset.

If a computer motherboard is held in a certain way, with the CPU socket as the north side, the chip that is connected to the CPU socket is called the "North Bridge chip". English name: North Bridge Chipset.

The northbridge chip is the most important component that plays a dominant role in the motherboard chipset, also known as the hostbridge.

The South Bridge chip is an important part of the motherboard chipset, which is mainly responsible for controlling the input and output parts of the motherboard, such as hard disks, I.O interfaces, etc. In order to reduce the size, power consumption and cost, some motherboards integrate the south bridge into the north bridge.

Lao Tie is actually very differentiated: the south bridge is in the south, and the north bridge is in the north, haha.

The north bridge chip is generally in the middle and upper part of the motherboard, below the CPU socket, there is generally a heat sink covered, mainly responsible for the communication and signal processing between the CPU, memory, and graphics card, and the south bridge chip is generally in the right position under the motherboard, the chip is larger than other chips, and some also have heat sinks, which are mainly responsible for the normal operation of various PCI slots, sound cards, network cards and other equipment, however, now many motherboard functions are integrated, and the south bridge chip can not be found.

The northbridge chip is the most important component that plays a dominant role in the motherboard chipset, also known as the hostbridge. The Northbridge chip is responsible for the contact with the CPU and controls the transmission of memory, AGP, and PCI data within the Northbridge, providing support for the type and frequency of the CPU, the front-side bus frequency of the system, the type of memory (SDRAM, DDR SDRAM, RDRAM, etc.) and maximum capacity, ISA PCI AGP slot, ECC error correction, etc., and the integrated chipset of the Northbridge chip also integrates the display core.

Southbridge chips are mainly responsible for data processing and transmission of external devices.

The main functions of the Northbridge chip are data transmission and signal control. On the one hand, it exchanges signals with the CPU through the front-side bus, and on the other hand, it has to exchange signals with memory, AGP, and Southbridge.

South Bridge: It is the input and output center, which is responsible for connecting the PCI bus and IDE devices The North Bridge: is the memory control center, which is responsible for the connection with the CPU, controlling the memory, and the transmission of AGP PCI data.

1. The north bridge is mainly responsible for coordinating the work of CPU, memory and other equipment, and the south bridge chip is responsible for graphics cards, sound cards, and PCI equipment.

2. The northbridge generally has a heat sink, close to the CPU, the main inside, and the northbridge chip, which is mainly responsible for controlling the data exchange between the AGP graphics card, memory and CPU.

3. At present, due to the improvement of technology and technology, all some motherboards have canceled the south bridge, and only one north bridge chip is responsible for the work of the entire motherboard equipment.

The origin of the North Bridge is determined by the CPU: if the CPU socket is the north, the chip that is connected to the CPU socket is called the "North Bridge chip". His role has 2 The first is to position the model and function of a motherboard, such as what kind of CPU does a motherboard support, what kind of memory, what kind of graphics card, which is determined by the chipset of Northbridge.

And secondly, I'm going to give you a quick rundown: the concept of a platform that he's a platform that he's making the hardware that he supports compatible I like to use analogies: let's say you have a lot of children, you're their elders, they're not born to know everybody, but you're going to teach them to know and be friends.

Got it?
