Platform Controller Hub

Over time, the speed of CPUs kept increasing but the bandwidth of the front-side bus (FSB) (connection between the CPU and the motherboard) did not, resulting in a performance bottleneck.

[needs update] AMD's FCH has been discontinued since the release of the Carrizo series of CPUs as it has been integrated into the same die as the rest of the CPU.

[8] AMD server and laptop CPUs adopt a self contained system on chip (SoC) design instead which doesn't require a chipset.

This has the following variations: Tiger Point is the codename of a PCH in the Pine Trail netbook platform chipset for Atom Pineview microprocessors.

This has the following variations: Topcliff is the codename of a PCH in the Queens Bay embedded platform chipset for Atom Tunnel Creek microprocessors.

This has the following variations: Cougar Point is the codename of a PCH in Intel 6 Series chipsets for mobile, desktop, and workstation / server platforms.

[16] This has the following variations: Cave Creek is the codename of the PCH most closely associated with Crystal Forest platforms and Gladden[17] or Sandy Bridge-EP/EN[18] processors.

It was initially launched in 2011 as part of Intel X79 for the desktop enthusiast Sandy Bridge-E processors in Waimea Bay platforms.

[21][22] Patsburg has the following variations: Coleto Creek is the codename of the PCH most closely associated with Highland Forest platforms and Ivy Bridge-EP[23] processors.

Lynx Point is the codename of a PCH in Intel 8 Series chipsets, most closely associated with Haswell processors with LGA 1150 socket.

[25] The following variants are available:[26] In addition the following newer variants are available, additionally known as Wildcat Point, which also support Haswell Refresh processors:[27] A design flaw causes devices connected to the Lynx Point's integrated USB 3.0 controller to be disconnected when the system wakes up from the S3 state (Suspend to RAM), forcing the USB devices to be reconnected although no data is lost.

[31] Wellsburg has the following variations: Sunrise Point is the codename of a PCH in Intel 100 Series chipsets, most closely associated with Skylake processors with LGA 1151 socket.

The following variants are available:[32] Union Point is the codename of a PCH in Intel 200 Series chipsets, most closely associated with Kaby Lake processors with LGA 1151 socket.

Lewisburg has the following variations: Basin Falls is the codename for the C400-series PCH, supporting Skylake-X/Kaby Lake-X processors (branded Core i9 Extreme and "Skylake-W" Xeon).

Basin Falls has the following variations: Cannon Point is the codename of a PCH in Intel 300 Series chipsets, most closely associated with Coffee Lake processors with LGA 1151 socket.
