List of AMD chipsets
This is an overview of chipsets sold under the AMD brand, manufactured before May 2004 by the company itself, before the adoption of open platform approach as well as chipsets manufactured by ATI Technologies after October 2006 as the completion of the ATI acquisition.
A-Link Express and A-Link Express II are essentially PCIe 1.1 x4 lanes.
See Comparison of ATI Chipsets for the comparison of chipsets sold under the ATI brand for AMD processors, before AMD's acquisition of ATI.
A-Link Express III is essentially PCIe 2.0 x4 lanes.
1 Parallel ATA, also known as Enhanced IDE supports up to 2 devices per channel.
1 Parallel ATA, also known as Enhanced IDE supports up to 2 devices per channel.
For AMD APU models from 2011 until 2016. AMD marketed their chipsets as Fusion Controller Hubs (FCH), implementing it across their product range in 2017 alongside the release of the Zen architecture. Before then, only APUs used FCHs, while their other CPUs still used a northbridge and southbridge. The Fusion Controller Hubs are similar in function to Intel's Platform Controller Hub.
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. However, since the release of the Zen architecture, there's still a component called a chipset which only handles relatively low speed I/O such as USB and SATA ports and connects to the CPU with a PCIe connection. In these systems all PCIe connections are routed directly to the CPU. The UMI interface previously used by AMD for communicating with the FCH is replaced with a PCIe connection. Technically the processor can operate without a chipset; it only continues to be present for interfacing with low speed I/O. AMD server CPUs adopt a self contained system on chip design instead which doesn't require a chipset.
