CPU socket for AMD Ryzen processors with Zen architecture
Socket AM5 (LGA 1718) is a zero insertion force flip-chip land grid array (LGA)[1] CPU socket designed by AMD that is used for AMD Ryzen microprocessors starting with the Zen 4 microarchitecture.[2] [3] AM4 .[4]
The Ryzen 7000 series processors were the first AM5 processors. The 7000 series added support for PCI Express 5.0 and DDR5 .[5]
Background [ edit ]
In March 2017, with the launch of its new Zen processors, AMD used the AM4 socket that they had previously used with their Bristol Ridge (derived from Excavator ) powered Athlon X4 and some A-Series, a pin grid array (PGA) socket that they promised to support until 2020.[6]
Announcement [ edit ]
At CES 2022 , AMD CEO Lisa Su unveiled the AM5 socket and the integrated heat spreader design for the upcoming Ryzen 7000 processors due in late 2022.
On May 23, 2022, AMD provided details about the AM5 socket, its corresponding motherboards , and Ryzen 7000 Series CPUs at Computex in Taipei , Taiwan.[7] ASRock , Gigabyte and others debuted their new X670 motherboards featuring the AM5 socket.[8] [9]
AMD stated that it plans to support the AM5 socket for a number of years as it did with the AM4 socket.[10] [11] At Computex 2024, AMD announced that this support period would then be extended through 2027.[12]
Features [ edit ]
Supports DDR5 in dual-channel configuration. DDR4 is not supported, unlike Intel's LGA 1700 socket.[13]
Support for PCIe 5.0 lanes from the CPU on X870E, X870, X670E and B650E chipsets.[14]
Achieves 170 W TDP[i] [ii] [15]

Heatsink [ edit ]
The AM5 socket specifies the 4 holes for fastening the heatsink to the motherboard to be placed in the corners of a rectangle with a lateral length of 54×90 mm, as well as UNC #6-32 screw threads for the backplate, identical to those of the preceding AM4 socket. Furthermore, the Z-height of the CPU package is kept the same as that of AM4, for backward compatibility of heatsinks.[16]
Unlike AM4, the backplate on AM5 is not removable, as it also serves the purpose of securing the CPU retention mechanism for the LGA socket.[17]
Not all existing CPU coolers from AM4 are compatible. In particular, coolers that use their own backplate mounting hardware, instead of the default motherboard-provided backplate, will not work. Some cooler manufacturers are offering upgrade kits to allow incompatible older coolers to be used on AM5.[18] [19]
