'''K12'''是[[AMD]]第一款基於[[ARMv8-A]]（[[AArch64]]）[[指令集]]的[[微架構]]，預計將在2016年公布。<ref>{{Cite web |url = http://www.anandtech.com/show/7990/amd-announces-k12-core-custom-64bit-arm-design-in-2016 |title = AMD Announces K12 Core: Custom 64-bit ARM Design in 2016 |author = Anand Lal Shimpi |date = 2014-05-05 |publisher = AnandTech |language = en |accessdate = 2015-02-24 |quote = In 2016 AMD will release its first custom 64-bit ARMv8 CPU core, codenamed K12. Jim Keller is leading the team that is designing the K12, as well as a corresponding new 64-bit x86 design. |archive-date = 2015-06-26 |archive-url = https://web.archive.org/web/20150626102331/http://www.anandtech.com/show/7990/amd-announces-k12-core-custom-64bit-arm-design-in-2016 |dead-url = no }}</ref>但隨著當時負責此專案的AMD首席架構師Jim Keller跳槽至特斯拉，K12專案也就不了了之。

== 基本介紹 ==
K12將基於[[格羅方德]]/[[三星電子|三星]] 14奈米[[多閘極電晶體#FinFET|FinFET]]的製程。<ref>{{cite AV media|url=http://www.youtube.com/watch?v=KlKXw8-csng&feature=youtu.be&t=1h17m26s|title=AMD Core Innovation Summit May 2014|date=May 19, 2014|access-date=2015-02-23|archive-date=2019-02-15|archive-url=https://web.archive.org/web/20190215105654/https://www.youtube.com/watch?v=KlKXw8-csng&feature=youtu.be&t=1h17m26s|dead-url=no}}</ref>

[[微架構]]將聚焦在[[高頻]]和電源效率，並將以高密度[[伺服器]]，嵌入式、半定制的[[市場區隔]]為目標。<ref>{{Cite web |url = http://techreport.com/review/26418/amd-reveals-k12-new-arm-and-x86-cores-are-coming |title = AMD reveals K12: New ARM and x86 cores are coming, Already deep into development |author = Scott Wasson |date = 2014-05-05 |publisher = The Tech Report |language = en |accessdate = 2015-02-24 |quote = ……We now know that AMD intends to compete where it has done well historically—in desktops, servers, and laptops, as well as embedded systems and mobile devices—by fielding CPUs compatible with the two major instruction set architectures: ARM and x86. |archive-date = 2015-02-23 |archive-url = https://web.archive.org/web/20150223194649/http://techreport.com/review/26418/amd-reveals-k12-new-arm-and-x86-cores-are-coming |dead-url = no }}</ref>
