===== ARM architecture-based designs =====
In 2012, AMD announced it was working on [[ARM architecture family|ARM]] products, both as a semi-custom product and server product.<ref>{{Cite news |last=Shimpi |first=Anand Lal |date=February 2, 2012 |title=AMD is Ambidextrous, Not Married to Any One Architecture, ARM in the Datacenter |publisher=Anandtech |url=http://www.anandtech.com/show/5501/amd-is-ambidextrous-not-married-to-any-one-architecture-arm-in-the-datacenter |access-date=July 11, 2017}}</ref><ref>{{Cite news |last=Shimpi |first=Anand Lal |date=February 2, 2012 |title=AMD: Flexible Around ISA |publisher=Anandtech |url=http://www.anandtech.com/show/5495/amd-flexible-around-isa |access-date=July 11, 2017}}</ref><ref>{{Cite news |last=Shimpi |first=Anand Lal |date=October 29, 2012 |title=AMD will build 64-bit ARM based Opteron CPUs for Servers, Production in 2014 |publisher=Anandtech |url=http://www.anandtech.com/show/6418/amd-will-build-64bit-arm-based-opteron-cpus-for-servers-production-in-2014 |access-date=July 11, 2017}}</ref> The initial server product was announced as the [[Opteron A1100]] in 2014, an 8-core [[Cortex-A57]]-based [[ARMv8-A]] [[System on a Chip|SoC]],<ref>{{Cite news |last=Shimpi |first=Anand Lal |date=January 28, 2014 |title=It Begins: AMD Announces Its First ARM Based Server SoC, 64-bit/8-core Opteron A1100 |publisher=Anandtech |url=http://www.anandtech.com/show/7724/it-begins-amd-announces-its-first-arm-based-server-soc-64bit8core-opteron-a1100 |access-date=July 11, 2017}}</ref><ref>{{Cite news |last=Barrett |first=Stephen |date=August 11, 2014 |title=AMD's Big Bet on ARM Powered Servers: Opteron A1100 Revealed |publisher=Anandtech |url=http://www.anandtech.com/show/8362/amds-big-bet-on-arm-powered-servers-a1100-revealed |access-date=July 11, 2017}}</ref> and was expected to be followed by an APU incorporating a [[Graphics Core Next]] GPU.<ref>{{Cite news |last=Shimpi |first=Anand Lal |date=May 5, 2014 |title=AMD Announces Project Skybridge |publisher=Anandtech |url=http://www.anandtech.com/show/7989/amd-announces-project-skybridge-pincompatible-arm-and-x86-socs-in-2015 |access-date=July 11, 2017}}</ref> However, the Opteron A1100 was not released until 2016, with the delay attributed to adding software support.<ref name="a1100_release">{{Cite news |last=De Gelas |first=Johan |date=January 14, 2016 |title=The Silver Lining of the Late AMD Opteron A1100 Arrival |publisher=Anandtech |url=http://www.anandtech.com/show/9956/the-silver-lining-of-the-late-amd-opteron-a1100-arrival |access-date=July 11, 2017}}</ref> The A1100 was also criticized for not having support from major vendors upon its release.<ref name="a1100_release" /><ref>{{Cite news |last=Kennedy |first=Patrick |date=July 5, 2017 |title=Most Impressive Part of the AMD EPYC Launch: The Ecosystem |publisher=Serve The Home |url=https://www.servethehome.com/impressive-part-amd-epyc-launch-ecosystem/ |access-date=July 11, 2017}}</ref><ref>{{Cite news |last=Kennedy |first=Patrick |date=January 14, 2016 |title=The AMD Opteron A1100 – An Editorial |publisher=Serve the Home |url=https://www.servethehome.com/the-amd-opteron-a1100-an-editorial/ |access-date=July 11, 2017}}</ref>

In 2014, AMD also announced the [[AMD K12|K12]] custom core for release in 2016.<ref>{{Cite news |last=Shimpi |first=Anand Lal |date=May 5, 2014 |title=AMD Announces K12 Core |publisher=Anandtech |url=http://www.anandtech.com/show/7990/amd-announces-k12-core-custom-64bit-arm-design-in-2016 |access-date=July 11, 2017}}</ref> While being [[ARMv8-A]] [[instruction set architecture]] compliant, the K12 was expected to be entirely custom-designed, targeting the server, embedded, and semi-custom markets. While ARM architecture development continued, products based on K12 were subsequently delayed with no release planned. Development of AMD's x86-based Zen microarchitecture was preferred.<ref>{{Cite news |last=Smith |first=Ryan |date=May 5, 2015 |title=AMD's K12 ARM CPU Now In 2017 |publisher=Anandtech |url=http://www.anandtech.com/show/9232/amds-k12-arm-cpu-now-in-2017 |access-date=July 11, 2017}}</ref><ref>{{Cite news |last=Cutress |first=Ian |date=January 24, 2018 |title=Getting Radeon Vega Everywhere |publisher=Anandtech |url=https://www.anandtech.com/show/12312/getting-radeon-vega-everywhere-an-exclusive-interview-with-dr-lisa-su-amd-ceo |access-date=January 31, 2018}}</ref>
