-->CHIPSET<--------------------------------
The chipset is the "glue" that connects the microprocessor to the rest
of the motherboard and therefore to the rest of the computer. On a PC,
it consists of two basic parts -- the northbridge and the southbridge.
All of the various components of the computer communicate with the CPU
through the chipset.
The northbridge
connects directly to the processor via the front side bus (FSB). A
memory controller is located on the northbridge, which gives the CPU
fast access to the memory. The northbridge also connects to the AGP or
PCI Express bus and to the memory itself.
The southbridge is slower
than the northbridge, and information from the CPU has to go through the
northbridge before reaching the southbridge. Other busses connect the
southbridge to the PCI bus, the USB ports and the IDE or SATA hard disk
connections.
Chipset selection and CPU selection go hand in hand,
because manufacturers optimize chipsets to work with specific CPUs. The
chipset is an integrated part of the motherboard, so it cannot be
removed or upgraded. This means that not only must the motherboard's
socket fit the CPU, the motherboard's chipset must work optimally with
the CPU.
