Before the launch of [[Athlon 64]] processors in 2003, AMD designed [[chipset]]s for their processors spanning the [[AMD K6|K6]] and [[AMD K7|K7]] processor generations. The chipsets include the AMD-640, AMD-751, and the AMD-761 chipsets. The situation changed in 2003 with the release of Athlon 64 processors, and AMD chose not to further design its own chipsets for its desktop processors while opening the desktop platform to allow other firms to design chipsets. This was the "[[Open Platform Management Architecture]]" with [[ATI Technologies|ATI]], [[VIA Technologies|VIA]] and [[Silicon Integrated Systems|SiS]] developing their own chipset for [[Athlon 64]] processors and later [[Athlon 64 X2]] and [[Athlon 64 FX]] processors, including the [[AMD Quad FX platform|Quad FX platform]] chipset from Nvidia.

The initiative went further with the release of [[Opteron]] server processors as AMD stopped the design of server chipsets in 2004 after releasing the AMD-8111 chipset, and again opened the server platform for firms to develop chipsets for Opteron processors. As of today,{{When|date=March 2021}} Nvidia and [[Broadcom]] are the sole designing firms of server chipsets for Opteron processors.

As the company completed the acquisition of ATI Technologies in 2006, the firm gained the ATI design team for chipsets which previously designed the [[Xpress 200|Radeon Xpress 200]] and the [[Xpress 3200|Radeon Xpress 3200]] chipsets. AMD then renamed the chipsets for AMD processors under AMD branding (for instance, the CrossFire Xpress 3200 chipset was renamed as [[AMD 580 chipset series|AMD 580X CrossFire chipset]]). In February 2007, AMD announced the first AMD-branded chipset since 2004 with the release of the AMD [[AMD 690 chipset series|690G]] chipset (previously under the development codename ''RS690''), targeted at mainstream [[Integrated Graphics Processor|IGP]] computing. It was the industry's first to implement a [[HDMI]] 1.2 port on motherboards, shipping for more than a million units. While ATI had aimed at releasing an Intel IGP chipset, the plan was scrapped and the inventories of [[AMD 690 chipset series#Radeon Xpress 1250|Radeon Xpress 1250]] (codenamed ''RS600'', sold under ATI brand) was sold to two OEMs, Abit and ASRock. Although AMD stated the firm would still produce Intel chipsets, Intel had not granted the license of {{nowrap|1333 MHz}} FSB to ATI.

On November 15, 2007, AMD announced a new chipset series portfolio, the [[AMD 700 chipset series|AMD 7-Series chipsets]], covering from the enthusiast multi-graphics segment to the value IGP segment, to replace the [[AMD 580 chipset series|AMD 480/570/580 chipsets]] and [[AMD 690 chipset series|AMD 690 series chipsets]], marking AMD's first enthusiast multi-graphics chipset. Discrete graphics chipsets were launched on November 15, 2007, as part of the codenamed ''Spider'' desktop platform, and IGP chipsets were launched at a later time in spring 2008 as part of the codenamed ''Cartwheel'' platform.

AMD returned to the server chipsets market with the [[AMD 800 chipset series|AMD 800S series server chipsets]]. It includes support for up to six [[Serial ATA#SATA Revision 3.0 (SATA 6Gb/s)|SATA 6.0 Gbit/s]] ports, the C6 power state, which is featured in [[AMD Fusion|Fusion]] processors and [[Advanced Host Controller Interface|AHCI]] 1.2 with SATA [[port multiplier#FIS(Frame Information Structure)–based switching|FIS-based switching]] support. This is a chipset family supporting [[AMD Phenom|Phenom]] processors and [[AMD Quad FX platform|Quad FX enthusiast platform]] (890FX), [[Integrated Graphics Processor|IGP]] (890GX).

With the advent of AMD's APUs in 2011, traditional northbridge features such as the connection to graphics and the PCI Express controller were incorporated into the APU die. Accordingly, APUs were connected to a single chip chipset, renamed the Fusion Controller Hub (FCH), which primarily provided southbridge functionality.<ref>{{Cite news |last=Wasson |first=Scott |date=June 22, 2011 |title=AMD's A8-3500M Fusion APU |publisher=Tech Report |url=https://techreport.com/review/21099/amd-a8-3500m-fusion-apu |access-date=July 10, 2017}}</ref>

AMD released new chipsets in 2017 to support the release of their new [[Ryzen]] products. As the [[Zen (microarchitecture)|Zen microarchitecture]] already includes much of the northbridge connectivity, the AM4-based chipsets primarily varied in the number of additional PCI Express lanes, USB connections, and SATA connections available.<ref name="chipset_toms">{{Cite news |last1=Justin |first1=Michael |last2=Sexton |first2=Allen |date=March 3, 2017 |title=AMD's AM4 Ryzen Chipsets |publisher=Tom's Hardware |url=http://www.tomshardware.com/news/amd-am4-ryzen-chipsets,33806.html |access-date=March 3, 2017}}</ref> These AM4 chipsets were designed in conjunction with [[ASMedia]].<ref name="su_interview">{{Cite news |last=Cutress |first=Ian |date=March 2, 2017 |title=Making AMD Tick: A Very Zen Interview it Dr. Lisa Su, CEO |publisher=Anandtech.com |url=http://www.anandtech.com/show/11177/making-amd-tick-a-very-zen-interview-with-dr-lisa-su-ceo |access-date=March 2, 2017}}</ref>
