Each chipset contains two components: GMCH (or MCH) for the host bridge and I/O Controller Hub 9 (ICH9) for the I/O subsystem. The 82Q33 GMCH is part of the Intel® Q35 Express chipset. The 82Q33 GMCH is part of the Intel® Q33 Express chipset. The 82G33 GMCH is part of the Intel® G33 Express chipset. The 82P35 MCH is part of the Intel® P35 Express chipset. The ICH9 is the ninth generation I/O Controller Hub and provides a multitude of I/O related functions. The following figures show example system block diagrams for the Intel® Q35, Q33, G33 and P35 Express chipsets.
