Socket AM3 (also known as Socket 941) is a socket for installing AMD processors. The AM3 socket was introduced in February 2009 and replaced the previous generation AM2+ socket. The main changes in the architecture of this connector include support for DDR3 SDRAM memory and a faster HyperTransport bus.

Later, AMD released the AM3+ socket (Socket 942), which is a modification of AM3. The AM3+ socket was created to support Zambezi (Bulldozer) processors. But, it is also backwards compatible. Thus, processors released for AM3 can be used on motherboards with AM3+. In some cases, processors for AM3+ can be used on motherboards with socket AM3, but in this case a Bios update is necessary.

• 938/940-pin lidded micro pin grid array package
• 16 bit HyperTransport interface
• 2 × 64/72 bit DDR2 SDRAM
• 2 × 64/72 bit DDR3 SDRAM
• Mixing of DDR2 and DDR3 

Chipsets

• AMD 700, 800, 900 series
• Nvidia nForce 630a, 980a SLI

Socket FM2 is a socket for installing hybrid processors (APU) from AMD. This connector was introduced in 2012 as a replacement for the FM1 socket. Even though FM2 is a receiver of FM1, these connectors are not compatible and it is not possible to install an FM2 processor into an FM1 motherboard (or vice versa).

Initially, Socket FM2 only supported dual- and quad-core APUs with the Trinity core. A little later, AMD also released Athlon processors for this socket, which are not equipped with integrated graphics. And in mid-2013, “Richland” APUs were introduced for Socket FM2.

Socket AM4 (also known as PGA 1331) is a socket for installing processors from AMD. This connector was introduced in 2016 and is intended for new AMD processors based on the Zen microarchitecture. However, for this socket there are also processors built on the Excavator microarchitecture.

The AM4 socket is a PGA (pin grid array) type socket and has 1331 pins. In addition to supporting new processors, this socket received other innovations that were not available on AMD sockets. For example, AM4 received support for DDR4 memory and processors with integrated graphics (previously, AMD had a separate socket for processors with integrated graphics).

Socket AM5 is a new socket for AMD Ryzen processors. In 2022, it replaced the AM4. AMD has developed both new processors and new chipsets for the socket.

The first processors for the AM5 socket were the Ryzen 7000 line. Three new AMD 600 series chipsets were developed for them. Two of them have a couple of varieties. Top models are X670 and X670E, mid-range - B650 and B650E, entry-level - A620. All motherboards with new chipsets use only DDR5 RAM. The reason is simple: the RAM controller in Ryzen 7000 processors does not support DDR4.
