The Northbridge is the portion of the chipset HUB that connects faster I/O buses (for example, an AGP bus) to the system bus. Northbridge SI also bigger looking then the Southbridge chip. The Southbridge is the HUB that connects to slower I/O buses (for example, An ISA bus) to the system bus.
The connection between the northbridge and southbridge does not have a common name, but was usually a high-speed interconnect proprietary to the chipset vendor. Before 2003, any interaction between a CPU and main memory or an expansion device such as a graphics card(s) â whether AGP, PCI or integrated into the motherboard â was directly controlled by the northbridge IC on behalf of the processor.
