The Northbridge chips communicate with the CPU through the FSB.The Northbridge chip is one of two chips that control the functions of the chipset. The other is the Southbridge. The Northbridge can consist of more than one discrete chip while the Southbridge is typically only one discrete chip.SouthbridgeThe Southbridge is the chip that controls all of the computers I/O functions, such as USB, audio, serial, the system BIOS, the ISA bus, the interrupt controller and the IDE channels. In other words, all of the functions of a processor except memory, PCI and AGP.ManufacturersIntel440 series800 series 850 & i845 – Pentium 4 HyperthreadingIntel ChipsetsManufacturersAMDAMD-760TM AMD-8000TMAMD-760 ChipsetVIA TechnologiesSocket AVIA Apollo KT333VIA Apollo KT266AVIA Apollo KT133A VIA Apollo KLE133Socket 478VIA Apollo P4X266A VIA Apollo P4X266Socket 370 / Slot 1VIA Apollo Pro266T VIA Apollo Pro133TVIA Apollo Pro133A(Dual CPU)VIA Apollo PLE133 VIA Apollo PLE133T VIA Apollo Pro PlusVIA Apollo Pro VIA ProSavage™ ChipsetsSilicon Integrated SystemsSiS655( North Bridge Chipset ) SiS748( North Bridge Chipset )Silicon Integrated SystemsBottom LineLots of chipsets to support processors as they
