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.
Accordingly, starting with the AMD Athlon64 series CPUs (based on the Opteron), a new architecture was used where some functions of the north-and southbridge chips were moved to the CPU. Modern Intel Core processors have the northbridge integrated on the CPU die, where it is known as the uncore or system agent.he northbridge is usually paired with a southbridge, also known as I/O controller hub. In systems where they are included, these two chips manage communications between the CPU and other parts of the motherboard, and constitute the core logic chipset of the PC motherboard.
