History
Early history
Northbridge (computing)
A northbridge or host bridge is one of the two chips in the core logic chipset architecture on a PC motherboard, the other being the southbridge. Unlike the southbridge, northbridge is connected directly to the CPU via the frontside bus (FSB) and thus responsible for tasks that require the highest performance. The 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.
On older Intel based PCs, the northbridge was also named external memory controller hub (MCH) or integrated memory controller hub (IMCH) if equipped with an integrated VGA memory controller hub (MCH). 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, while some high-performance CPUs still require northbridge and southbridge chips externally.
