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.

Fusion controller hubs (FCH)

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.

In addition to their traditional chipsets, AMD also offers "processor-direct" chipsets for "small, simple" motherboards. AMD describes the A300 chipset as intended for consumers, the X300 chipset for "enthusiasts and overclockers", and the PRO 500 chipset for commercial users.^[12] The A300 chipset is referred to by Elitegroup as "A300 Knoll Express", and in a corresponding manual as an "AMD KNOLL" chipset.^[13][14] Enthusiast publication igor'sLAB obtained leaked documents that describe an AMD "Knoll Activator" chip for board partners that enables "activating... processor I/O and processor features in the absence of an alternative AMD chipset." They conclude that motherboards and systems can be built with the native processor I/O, a Knoll Activator, and cheap I/O chips in lieu of a chipset.^[15]

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.^[16][17]

1. PCIe lanes provided by the chipset. The CPU provides other PCIe 3.0 or 4.0 lanes. Chipset uplink to CPU is PCIe 3.0 ×4 (X570: PCIe 4.0 ×4)
2. USB 3.2 Gen 2, USB 3.2 Gen 1, USB 2.0
3. BIOS update needed. Availability may depend on manufacturer.
4. Beta BIOS updates may be made available by motherboard manufacturers.
5. OEM-only B550A is a rebranded B450
6. 7W on passive cooling (termed X570s).
7. Uplink incompatible with Excavator.

The 300 series, 400 series, and the B550 chipsets are designed in collaboration with ASMedia and the family is codenamed Promontory.^[29] The X570 is designed by AMD with IP licensed from ASMedia and other companies and is codenamed Bixby.^[30] Network interface controller, Wi-Fi, and Bluetooth are provided by external chips connected to the chipset through PCIe or USB. All 300 series chipsets are made using 55 nm lithography.^[31] The X570 chipset is a repurposed Matisse/Vermeer IO die made using the 14 nm Global Foundries process.^[32]

Although the X399, TRX40 and WRX80 motherboards' CPU sockets use the same number of pins, the sockets are incompatible with each other due to ID pins and no-connects of some pins. Twelve TRX40 motherboards were released at launch in November 2019. The TRX40 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.^[35]

Although the X399, TRX40 and WRX80 motherboards' CPU sockets use the same number of pins, the sockets are incompatible with each other due to ID pins and no-connects of some pins.^[35] Three WRX80 motherboards were released at launch in March 2021. The WRX80 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 WRX80 motherboards to integrate audio codecs.

AM5 chipsets

AMD uses a single Promontory 21 chipset for all configurations that include a chipset. A single Promontory 21 chip provides four SATA III ports and twelve PCIe 4.0 lanes. Four lanes are reserved for the chipset uplink to the CPU while another four are used to connect to another Promontory 21 chip in a daisy-chained topology for X670 chipsets.^[38]

1. PCIe lanes provided by the chipset. The CPU provides other PCIe 5.0 lanes.
2. E or "Extreme" branding is a guarantee that PCIe 5.0 is supported on both the motherboard's graphics slot and NVMe slots. E models provide access to all 24 PCIe 5.0 lanes from the processor. Non-E models only support 8 PCIe 5.0 lanes on NVMe slots while the rest of the lanes on graphics slots are dropped to PCIe 4.0.
3. Each Promontory 21 chipset provides 4 SATA ports for a total of 8.
4. Motherboards marketed as X670 and X670E feature two Promontory 21 chipsets, each having a TDP of ~7W.
