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.
14 × USB 2.0, 2 × SATA 1.5/3/6 Gbit/s + 4 × SATA 1.5/3 Gbit/s, Integrated LAN, Integrated Graphics, Intel Anti-Theft Technology, Active Management Technology 7.0 Dual processor Sandy Bridge -based Xeon chipsets
The PCIe 2.0 lanes from the PCH ran at 5 GT/s in this series, unlike in the previous LGA 1156 chips. [ 78 ] The Cougar Point Intel 6 series chipsets with stepping B2 were recalled due to a hardware bug that causes their 3 Gbit/s Serial ATA to degrade over time until they become unusable.
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.
Intel X99, codenamed "Wellsburg", is a Platform Controller Hub (PCH) designed and manufactured by Intel, targeted at the high-end desktop (HEDT) and enthusiast segments of the Intel product lineup. [ 2 ] : 10 The X99 chipset supports both Intel Core i7 Extreme and Intel Xeon E5-16xx v3 and E5-26xx v3 processors , which belong to the Haswell-E ...
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]
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 ...
