| An
integrated circuit (generally Intel or VIA) that is responsible for
the communications between the
CPU interface, AGP,
PCI and the memory. The
northbridge gets its name for commonly being North of the
PCI bus. Below is a graphic illustration of
the ASUS P5AD2-E motherboard and
some basic explanations of each of the major portions of the
motherboard, including the northbridge. As shown in the below picture,
it's common for the northbridge and southbridge to have a heatsink;
in addition, the northbridge is usually slightly larger than the
southbridge.
Some newer motherboards have
replaced the northbridge and the southbridge with IHA.
