AMD Announces K12 Core: Custom 64-bit ARM Design in 2016
 

In 2015 AMD will launch project Skybridge, a pair of pin-compatible ARM and x86 based SoCs. Leveraging next generation Puma+ x86 cores or ARM's Cortex A57 cores, these SoCs form the foundation of the next phase in AMD's evolution where ARM and x86 are treated like equal class citizens. As I mentioned in today's post however, both of these designs really aim at the lower end of the performance segment. To address a higher performance market, AMD is doing what many ARM partners have done and is leveraging an ARM architecture license to design their own microarchitecture.
