caption_attribution_description: English: An Intel PCH with a exposed die installed on a H81 chipset motherboard.
context_page_description: The Platform Controller Hub is a family of Intel chipsets, introduced circa 2008. It is the successor to the Intel Hub Architecture, which used a northbridge and southbridge instead, and first appeared in the Intel 5 Series.
  The PCH controls certain data paths and support functions used in conjunction with Intel CPUs. These include clocking, Flexible Display Interface and Direct Media Interface, although FDI is used only when the chipset is required to support a processor with integrated graphics. As such, I/O functions are reassigned between this new central hub and the CPU compared to the previous architecture: some northbridge functions, the memory controller and PCI-e lanes, were integrated into the CPU while the PCH took over the remaining functions in addition to the traditional roles of the southbridge. AMD has its equivalent for the PCH, known simply as a chipset, no longer using the previous term Fusion controller hub since the release of the Zen architecture in 2017.

  The PCH controls certain data paths and support functions used in conjunction with Intel CPUs. These include clocking (the system clock), Flexible Display Interface (FDI) and Direct Media Interface (DMI), although FDI is used only when the chipset is required to support a processor with integrated graphics. As such, I/O functions are reassigned between this new central hub and the CPU compared to the previous architecture: some northbridge functions, the memory controller and PCI-e lanes, were integrated into the CPU while the PCH took over the remaining functions in addition to the traditional roles of the southbridge.
