Cpu chipset

The chipset is a core part of the motherboard and can be compared to the bridge between the CPU and peripheral devices. According to the arrangement position on the main board, it is usually divided into the north bridge chip and the south bridge chip. The Northbridge chip provides support for CPU type and frequency, memory type and maximum capacity, ISA/PCI/AGP slots, and ECC error correction. Southbridge provides support for KBC (Keyboard Controller), RTC (Real-Time Clock Controller), USB (Universal Serial Bus), Ultra DMA/33(66)EIDE data transfer, and ACPI (Advanced Energy Management) . The North Bridge chip plays a dominant role, also known as the Host Bridge. The identification of the chipset is also very easy. Take the Intel 440BX chipset as an example. Its Northbridge chip is an Intel 82443BX chip. It is usually located near the CPU slot on the motherboard. Because the chip's heat is higher, it is mounted on this chip. heat sink. The South Bridge chip is located close to the ISA and PCI slots. The chip's name is Intel 82371EB. The other chipsets are arranged in the same position. For different chipsets, there is also a gap in performance. In addition to the most common North-South bridge structure, the current chipset is developing to a more advanced accelerated hub architecture. Intel's 8xx series chipset is representative of this type of chipset, it will be a number of subsystems such as IDE interfaces, sound effects, MODEM and USB directly connected to the main chip, can provide twice the bandwidth of the PCI bus, reaching 266MB / s.
