Short for Intel Hub Architecture, IHA is the replacement for the Northbridge and Southbridge found on computer motherboards. The IHA is found on all Intel 800 series chipsets, and like its predecessor it has two parts: the GMCH and the ICH.

The GMCH, or Graphics and AGP Memory Control Hub, is similar to the Northbridge and helps control the AGP and memory.

The ICH, or I/O Controller Hub for short, is similar to the Southbridge and is responsible for the I/O ports and PCI controller.
