2022年1月4日，AMD正式确认了Socket AM5和Ryzen 7000系列将成为2022年产品发布的一部分。<ref>{{Citation|title=AMD 2022 Product Premiere - Recap|url=https://www.youtube.com/watch?v=X-7naMLoTQE|accessdate=2022-07-14|language=zh-CN|archive-date=2022-05-25|archive-url=https://web.archive.org/web/20220525203332/https://www.youtube.com/watch?v=X-7naMLoTQE|dead-url=no}}</ref>

2022年5月23日，AMD在[[台北國際電腦展覽會]]（Computex）发布了AM5接口并提供了有关信息<ref>{{Cite news|title=Dr. Lisa Su is teasing AMD Zen 4 CPU details on Monday and Gigabyte is promising AM5 boards|url=https://www.pcgamer.com/dr-lisa-su-is-teasing-amd-zen-4-cpu-details-on-monday-and-gigabyte-is-promising-am5-boards/|newspaper=PC Gamer|date=2022-05-20|accessdate=2022-07-14|language=en|first=Dave James|last=published|archive-date=2022-05-27|archive-url=https://web.archive.org/web/20220527181205/https://www.pcgamer.com/dr-lisa-su-is-teasing-amd-zen-4-cpu-details-on-monday-and-gigabyte-is-promising-am5-boards/|dead-url=no}}</ref>，随后，[[技嘉科技|技嘉]]、[[華擎科技|华擎]]等公司也确认了它们将即将发售基于AM5的[[主板]]，这些主板将基于新的X670/X670E芯片组。<ref>{{Cite web |last=Brandon Hill published |date=2022-05-20 |title=Gigabyte Confirms X670 AMD Ryzen 7000 Zen 4 AM5 Motherboards for Computex |url=https://www.tomshardware.com/news/gigabyte-x670-ryzen-7000-am5-zen4-computex-2022 |website=Tom's Hardware |language=en |access-date=2022-07-14}}</ref><ref>{{Cite web |last=published |first=Mark Tyson |date=2022-05-20 |title=Computex Organizer Confirms ASRock AMD X670E Motherboards Incoming |url=https://www.tomshardware.com/news/asrock-amd-x670E-motherboards-computex-2022 |website=Tom's Hardware |language=en |access-date=2022-07-14}}</ref>华擎随后又公布了基于B650芯片组的主流主板。<ref>{{Cite web |title=“中端旗舰”，华擎曝光 AMD 新一代 B650E 主板 - IT之家 |url=https://www.ithome.com/0/629/018.htm |website=www.ithome.com |access-date=2022-07-14 |archive-date=2022-07-14 |archive-url=https://web.archive.org/web/20220714110518/https://www.ithome.com/0/629/018.htm |dead-url=no }}</ref>

== 构成 ==
Socket AM5拥有1718个[[针脚]]，与Intel的[[LGA 1700]]类似，相较于[[Socket AM4]]的1331个针脚有所增加，但仍支持Socket AM4的散热解决方案。并将前代的[[插针网格阵列封装]]（PGA）封装升级为[[平面网格阵列封装]]（LGA）封装设计。相较于PGA，这种设计可减少针脚损坏的问题并可增加脚位。此外，AM5接口的供电也有所升级，达到了170W的TDP与230W的最高供电<ref>{{Cite web |last=published |first=Paul Alcorn |date=2022-05-26 |title=AMD Corrects Socket AM5 for Ryzen 7000 Power Specs: 230W Peak Power, 170W TDP (Updated) |url=https://www.tomshardware.com/news/amd-corrects-socket-am5-for-ryzen-7000-power-specs-230w-peak-power-170w-tdp |website=Tom's Hardware |language=en |access-date=2022-07-14}}</ref>，并支持[[PCI Express|PCIe 5.0]]和[[IEEE 802.11ax|WIFI 6E]]技术。<ref>{{Cite web |title=Meet The New AMD Socket AM5 Platform: Change The Game Once Again |url=https://www.amd.com/en/partner/amd-socket-am5-the-platform-set-to-change-gaming |access-date=2022-07-14 |archive-date=2022-08-06 |archive-url=https://web.archive.org/web/20220806161357/https://www.amd.com/en/partner/amd-socket-am5-the-platform-set-to-change-gaming |dead-url=no }}</ref>值得注意的是，Socket AM5将不再支持[[DDR4 SDRAM|DDR4]]，并新增对[[DDR5 SDRAM|DDR5]]的支持。<ref>{{Cite news|title=AMD's AM5 platform won't support DDR4 at launch|url=https://www.pcgamer.com/amds-am5-platform-wont-support-ddr4-at-launch/|newspaper=PC Gamer|date=2022-04-25|accessdate=2022-07-14|language=en|first=Alan Dexter|last=published|archive-date=2022-05-27|archive-url=https://web.archive.org/web/20220527092543/https://www.pcgamer.com/amds-am5-platform-wont-support-ddr4-at-launch/|dead-url=no}}</ref>AMD计划给予AM5接口5年的支持，与AM4平台类似。<ref>{{Cite web |last=Hagedoorn |first=Hilbert |title=AMD aims for AM5 to have a similar lifespan to AM4 (5 years) |url=https://www.guru3d.com/news-story/amd-aims-for-am5-to-have-a-similar-lifespan-to-am4-(5-years).html |website=Guru3D.com |language=en-us |access-date=2022-07-14 |archive-date=2022-01-10 |archive-url=https://web.archive.org/web/20220110115932/https://www.guru3d.com/news-story/amd-aims-for-am5-to-have-a-similar-lifespan-to-am4-(5-years).html |dead-url=no }}</ref>

== 特点 ==

* 与Intel的[[LGA 1700]]插槽不同，AMD 的 AM5 平台将不支持[[DDR4 SDRAM|DDR4]]内存，在双通道配置中只会支持 [[DDR5 SDRAM|DDR5]]。<ref>{{Cite news|title=AMD's AM5 platform won't support DDR4 at launch|url=https://www.pcgamer.com/amds-am5-platform-wont-support-ddr4-at-launch/|newspaper=PC Gamer|date=2022-04-25|accessdate=2022-07-26|language=en|first=Alan Dexter|last=published|archive-date=2022-05-27|archive-url=https://web.archive.org/web/20220527092543/https://www.pcgamer.com/amds-am5-platform-wont-support-ddr4-at-launch/|dead-url=no}}</ref>
* 支持[[PCI Express|PCIe 5.0]]。

== 芯片组 ==
AMD首批公布了3款芯片组：X670E、X670、B650。其中X670E有2个显卡插槽和1个存储插槽支持 PCIe 5.0。X670有1个同时支持显卡和存储的PCIe 5.0通道，而B650僅能提供PCIe 5.0存储支持。<ref>{{Cite web |title=AMD AM5 平台重新定义游戏体验 |url=https://www.amd.com/zh-hans/partner/amd-socket-am5-the-platform-set-to-change-gaming}}</ref>发布较晚的A620芯片组则不支持PCIe 5.0。
