Fusion controller hubs (FCH)

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.

Fusion Controller Hub A88X

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.[9] 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.[10] 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.[11][12][13][14]

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 offers chipsets with "processor-direct access", exclusively through OEM partners.[18] Enthusiast publication igor'sLAB obtained leaked documents about an AMD "Knoll Activator" that enables "activating... processor I/O and processor features in the absence of an alternative AMD chipset." It is concluded that motherboards with the Knoll Activator would be built with I/O from the processor and low-cost I/O chips.[19]

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.[20][21]

The 300 series, 400 series, and the B550 chipsets are designed in collaboration with ASMedia and the family is codenamed Promontory.[41] The X570 is designed by AMD with IP licensed from ASMedia and other companies and is codenamed Bixby.[42] 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.[43] The X570 chipset is a repurposed Matisse/Vermeer IO die made using a 14 nm process.[44]

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.[47]

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, X670E and X870E chipsets.[50]

  6. ^ a b The motherboard maker may configure the USB 3.2 provided by the chipset as 10× 3.2 Gen 2x1 and 1× 3.2 Gen 2x2 ports, or 12× 3.2 Gen 2x1 and 0× 3.2 Gen 2x2 ports.
  7. ^ a b Two Promontory 21 chipsets are present, each having a TDP of ~7 W, giving a total TDP of ~14 W.

sTR5 chipsets

The sTR5 socket has two chipset options available, TRX50 and WRX90:

  • TRX50 is an HEDT (High-End Desk-Top) platform which is intended to be paired with Threadripper (7000X) series processors, but is also compatible with Threadripper Pro models. When a Threadripper Pro CPU is paired with a TRX50 motherboard, extra features like enterprise management and security won't be available to the user, and PCIe lanes and memory channels will still be limited to that of non-Pro Threadripper.
  • WRX90 is a workstation platform for Threadripper Pro (7000WX) series processors. It is not compatible with the Threadripper non-Pro 7000X series.[59]

HD audio support is provided by the CPU, rather than by the chipset.[60]
