In personal home computers, gaming consoles and arcade game hardware in the 1980s and 1990s, the term chipset referred to the custom audio and graphics chips. These include the Commodore Amiga's Original Chip Set. Based on Intel Pentium-class microprocessors, the term chipset generally refers to a particular pair of chips on the motherboard. These are the northbridge and the southbridge. The northbridge links the CPU to high-speed devices, particularly main memory and graphics controllers, while the southbridge connects to slower peripheral buses such as PCI or ISA.
