Advanced Micro Devices (AMD) Chipsets
Although most people think the microprocessor is the most important part on a computers
motherboard, the "chipset" is equally important. The chipset consists of a northbridge
chip that connects the microprocessor to the systems memory, and a southbridge chip
that provides connections to the hard drive and USB ports. The northbridge and southbridge
chips communicate over the Peripheral Component Interconnect (PCI) bus, which also provides
The AMD-750 was AMD's first chipset. It was designed to support Athlon and Duron processors.
The AMD-750 chipset consists of the AMD-751 system controller (Northbridge) and the AMD-756
peripheral bus controller (Southbridge).
