The Platform Controller Hub (PCH) is a family of Intel's single-chip chipsets, first introduced in 2009. It is the successor to the Intel Hub Architecture, which used two chips–a northbridge and southbridge, and first appeared in the Intel 5 Series. The PCH controls certain data paths and support functions used in conjunction with Intel CPUs.
The Intel X79 (codenamed Patsburg) is a Platform Controller Hub (PCH) designed and manufactured by Intel for their LGA 2011 (Socket R) and LGA 2011-1 (Socket R2).. Socket and chipset support CPUs targeted at the high-end desktop (HEDT) and enthusiast segments of the Intel product lineup: Core i7-branded and Xeon-branded processors from the Sandy Bridge and Ivy Bridge CPU architectures.
With the Intel 5 Series chipset in 2008, the southbridge became redundant and was replaced by the Platform Controller Hub (PCH) architecture introduced. AMD did the same with the release of their first APUs in 2011, naming the PCH the fusion controller hub (FCH), which was only used on AMD's APUs until 2017 when it began to be used on AMD's Zen ...
Typically in server platforms, CPUs are the PECI slaves and Platform Controller Hub (PCH) is the PECI master, meanwhile in client segment, CPU is usually the PECI slave and EC/BMC is the PECI master. PECI was introduced in 2006 with the Intel Core 2 Duo microprocessors. Support for PECI was added to the Linux kernel version 5.18 in 2022. [1]
DMI 1.0, introduced in 2004 with a data transfer rate of 1 GB/s with a ×4 link. DMI 2.0 , introduced in 2011, doubles the data transfer rate to 2 GB/s with a ×4 link. It is used to link an Intel CPU with the Intel Platform Controller Hub (PCH), which supersedes the historic implementation of a separate northbridge and southbridge.
A typical north/southbridge layout (2015) A typical north/southbridge layout (2007) In computing, a northbridge (also host bridge, or memory controller hub) is a microchip that comprises the core logic chipset architecture on motherboards to handle high-performance tasks, especially for older personal computers.
The Basic Economics Test or BET is a standardized test of economics nationally norm-referenced in the United States for use in the upper-grade levels of elementary schools. It is one of four grade-level specific standardized economics tests (i.e., Test of Economic Knowledge (TEK), Test of Economic Literacy (TEL) and Test of Understanding in College Economics (TUCE)) sponsored and published by ...
PCH chipsets have a package size of 27mm x 27mm. The PCH serves out LGA 1156 and LGA 1366 sockets. The PCH is a class of chipsets. Each chipset has a set of information that can be added.
