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 (ATI) after July 2006 as the completion of the ATI acquisition.

Irongate chipset family; early steppings had issues with AGP 2×; drivers often limited support to AGP 1×; later fixed with "super bypass" memory access adjustment.[1]
AMD-760 chipset AMD-761 Nov 2000 Athlon, Athlon XP, Duron (Socket A), Alpha 21264 133 (FSB) AMD-766, VIA-VT82C686B AGP 4×, DDR SDRAM
AMD-760MP chipset AMD-762 May 2001 Athlon MP 133 (FSB) AMD-766 AGP 4×
AMD-760MPX chipset AMD-768 AGP 4×, Hardware RNG
Most initial boards shipped without USB headers due to a fault with the integrated USB controller. Manufacturers included PCI USB cards to cover this shortcoming. A later refresh of the chipset had the USB problem remedied.[2]
AMD-8000 series chipset AMD-8111 Apr 2004 Opteron 800 (HT 1.x) AMD-8131 AMD-8132 Hardware RNG

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.

Fusion controller hubs (FCH)
AMD Chipset Logo (used around 2013 till 2016).
Fusion Controller Hub A88X

For AMD APU models from 2011 until 2016. AMD is marketing 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.

AM4 chipsets
AMD B350 Chipset
AMD B450 Chipset

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.[12][13]

  1. PCIe lanes provided by the chipset. The CPU provides other PCIe 3.0 or 4.0 lanes.
  2. BIOS update needed. Availability may depend on manufacturer.
  3. Beta BIOS updates may be made available by motherboard manufacturers.

The 300 series, 400 series, and the B550 chipset are designed in collaboration with ASMedia.[25] The X570 is designed by AMD with IP licensed from ASMedia and other companies.[26] 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.[27] The X570 chipset is a repurposed Matisse IO die made using the 14 nm Global Foundries process.[28]

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 or a PCIe audio device on TRX40 motherboards to integrate audio codecs.[31]
