North Bridge
The northbridge or host bridge was one of the two chips in the core logic chipset on
a PC motherboard, used to managedata communications between a CPU and a
motherboard. It is supposed to be paired with a second support chip known as
a southbridge.
The northbridge was historically one of the two chips in the core logic chipset on a PC
motherboard, the other being thesouthbridge. Increasingly these functions became
integrated into the CPU chip itself, beginning with memory and graphics controllers.
For Intel Sandy Bridge and AMD Accelerated Processing Unit processors introduced in
2011, all of the functions of the northbridge reside on the CPU. When a separate
northbridge is employed in older Intel systems, it is named memory controller
hub (MCH) or integrated memory controller hub (IMCH) if equipped with an integrated
VGA.

Architecture
The north bridge is a controller which
controls the flow of data between the CPU and
RAM, and to the AGP port. The north bridge has a
large heat sink attached to it. It gets hot because of the often very large amounts of data
traffic which pass it. The AGP is actually an I/0 port. It is used for the video card. In
