Generally responsible for the contact with the CPU and control of memory, AGP data transmission in the north bridge, providing the type and main frequency of the CPU, the front-end bus frequency of the system, the type of memory (SDRAM, DDR SDRAM and RDRAM, etc.) and the maximum capacity, AGP slot, ECC error correction support, etc. The integrated chipset's Northbridge chip also integrates the display core. The North bridge chip is closest to the CPU, which is mainly due to the fact that the communication between the North bridge chip and the processor is the closest, and the transmission distance is shortened in order to improve the communication performance.
Because the data processing capacity of the North bridge chip is very large, the heat is getting larger and larger, so the current North bridge chip is covered with heat sinks to strengthen the heat dissipation of the North bridge chip, and the North bridge chip of some motherboards will also cooperate with the fan for heat dissipation.
Because the main function of the North bridge chip is to control the memory, and the memory standard and the processor change more frequently, so different chipsets in the North bridge chip is definitely different, of course, this is not to say that the memory technology used is completely different, but different chipsets between the North bridge chip must be different in some places.
The south bridge will be slightly farther away (due to the continuous improvement of modern chip technology, the temperature of the chip has become very high, the former South bridge chip is generally not covered by the heat sink, but now most of the South bridge chip is also covered by the heat sink), generally near the PCI, PCI-E, AGP and other slots.
Of course, there are also North-South bridge chips (nVidia, also known as NVIDIA, has some chipsets north-south bridge).
The chip next to the CPU has many small components, respectively. Word library, power amplifier (one accepts a emission) and resistance capacitance, power supply, etc., different sizes of electronic components are distributed around the CPU, each component division of labor is more detailed, the computer is also, the computer bridge, the north bridge, there are electromagnetic coils around, there are resistors, capacitors, each responsible for the work in order to make the computer run normally.
