List of AMD chipsets


This is an overview of chipsets sold under the brand AMD, manufactured before May 2004 by the company itself, before the adoption of open platform approach as well as chipsets manufactured by ATI Technologies after July 2006 as the completion of the ATI acquisition.

Northbridges

AMD-xxx

A-Link Express II

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

A-Link Express III is essentially PCIe 2.0 x4 lanes.

Southbridges

AMD-xxx

1 Parallel ATA, also known as Enhanced IDE supports up to 2 devices per channel.

Fusion controller hubs (FCH)

For AMD APU models from 2011 until 2016. AMD now simply calls their FCHs chipsets, 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. Similar in function to Intel's Platform Controller Hub.
Note 1: Supports SDHC up to 32 GB, 4 pins @ 50 MHz.

AM4 chipsets

There are currently 3 generations of AM4-based chipsets on the market. Models beginning with the numeral "3" are representatives of the first generation, those with "4" the second generation, etc.
Individual chipset models differ in the number of PCI Express lanes, USB ports, and SATA connectors, as well as supported technologies; the table below shows these differences.
The 300 and 400 series chipsets, as well as the B550 chipset, are designed in collaboration with ASMedia. The X570 is designed by AMD with IP licensed from ASMedia and other companies. Network interface controller, Wi-Fi, and Bluetooth are provided by external chips connected to the chipset through PCIe or USB. All 300/400 series chipsets are made using 55 nm lithography. The X570 chipset is a repurposed Matisse IO die made using the 14nm Global Foundries process.

TR4 chipsets

Supports both 1st and 2nd Gen AMD Ryzen Threadripper processors.

sTRX4 chipsets

Supports 3rd-generation AMD Ryzen Threadripper processors.
Although the X399 and TRX40 motherboards' CPU sockets use the same number of pins, the sockets are incompatible with each other due to different pin layouts. Twelve TRX40 motherboards were released at launch in November 2019. The sTRX4 chipset does not support the HD Audio interface on its own, so motherboard vendors must include a USB audio device on TRX40 motherboards to integrate HD audio codecs.
