Socket AM5 (LGA 1718) is a zero insertion force flip-chip land grid array (LGA)[1] CPU socket designed by Advanced Micro Devices, that is used for AMD Ryzen microprocessors starting with the Zen 4 microarchitecture.[2][3] AM5 replaces the Socket AM4 and is AMD's first LGA socket designed for mainstream, non-enthusiast CPUs.

AMD officially confirmed details about the Ryzen 7000 series platform, including support for PCI Express 5.0 and DDR5 as part of their 2022 Product Premiere.[4]

Background

In March 2017, with the launch of its new Zen processors, AMD introduced the AM4 socket, a pin grid array (PGA) socket that they promised to support until 2020.[5] In April 2022, AMD released its final CPU for the AM4 socket, the 5800X3D, which featured 96MB of 3D-stacked L3 cache.[6]

Announcement

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] At Computex, motherboard vendors 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] During the Ryzen 7000 series reveal on August 29, 2022, AMD confirmed that it would support the AM5 socket until at least "2025".[11]

Features

  • Supports DDR5 SDRAM in dual-channel configuration. Unlike Intel's LGA 1700 socket, AMD's AM5 platform does not support DDR4.[12]
  • Support for CPU PCIe 5.0 on X670E and B650E, optional on X670 and B650 chipsets[13].
  • Achieves 170W TDP[lower-alpha 1] and a Package Power Tracking (PPT)[lower-alpha 2] limit up to 230W.[14]

Heatsink

The AM5 socket is backwards compatible with existing AM4 CPU coolers.[15]
