What s the use of the computer South Bridge and North Bridge?

Fast transfer speed from the CPU. If it's farther away, it's slower. You all know the South Bridge and the North Bridge, so I don't need to say too much.

Satisfied with my opinion. I'm in a hurry to get a score.

The south bridge of the computer and the north bridge refer to the south bridge chip and the north bridge chip.

If a computer motherboard is north of the CPU socket, a chip that plays a connecting role near the CPU socket is called a "North Bridge Chipset", English name: North Bridge Chipset. The northbridge chip is the chip closest to the CPU on the motherboard, which is mainly due to the fact that the communication between the northbridge chip and the processor is the closest, and the transmission distance is shortened in order to improve the communication performance.

The South Bridge chip (South Bridge) is an important part of the motherboard chipset, which is generally located on the motherboard far from the CPU socket below, in front of the PCI, that is, on the front side of the main chassis, this layout is to consider that it is connected to more IO buses, and a little farther away from the processor is conducive to wiring.

Compared with the north-bridge chip, its amount is not large, so the south-bridge chip generally does not cover the heatsink, but now the south-bridge of the high-end motherboard also covers the heatsink.

The Southbridge chip is not directly connected to the processor, but is connected to the Northbridge chip in a certain way (different chipsets vary from manufacturer to manufacturer, such as Intel's Intel Hub Architecture and SIS's Multi-Threaded "Miaoqu").

The south bridge chip and the north bridge chip are an important part of the motherboard chipset, which is generally located below the CPU socket far away from the CPU socket on the motherboard, near the PCI socket, this layout is to take into account the fact that it is connected to more IO buses, and it is far away from the processor to facilitate wiring.

I drew a red circle on the south and north bridges.

The reason why the north bridge has a heat sink has been answered, and the addition is that the motherboard of the south bridge is a little better also has a heat sink. One of the reasons why Beiqiao is close to the CPU is that Beiqiao will spend more time dealing with the CPU (from the amount of heat dissipation and the object of treatment), which is convenient for neighbors to communicate.

Reason 2: Touching the "atmosphere" of the CPU. Isn't this society particular about green energy saving, and the wind from the fan on the CPU also blows casually to the neighbors, because the north bridge is also a heat sink, how pitiful, a little wind heat dissipation is much better.

I don't know for any other reason.

The South Bridge chip is an important part of the motherboard chipset, which is generally located on the motherboard far from the CPU socket below, near the PCI socket, this layout is to consider that it is connected to more IO buses, and a little farther away from the processor is conducive to wiring.

The northbridge chip is the dominant component of the motherboard chipset, also known as the hostbridge. Northbridge is one of two large-scale chips in the PC motherboard chipset. The northbridge is used to process high-speed signals, typically the CPU (processor), RAM (memory), AGP port or PCI Express, and the communication between the southbridge chip.

If it's a dual-chip motherboard.

So close to the CPU is the Northbridge chip.

And close to the hard disk interface is the South Bridge.

There is no distinction between a single chip.

Northbridge is responsible for contacting the CPU and controlling the memory (limited to Intel's CPUs other than the Core series, AMD series CPUs have integrated memory controllers in the CPU since the K8 series, so the AMD platform's Northbridge chips do not control the memory), AGP data is transmitted inside Northbridge, providing access to 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 the maximum capacity, AGP slot, ECC error correction and other support, the integrated chipset's Northbridge chip also integrates a graphics processor.
