K12 was to be AMD's first custom microarchitecture based on the ARMv8-A (AArch64) instruction set[1] with a planned release in 2017.[2][3] Its predecessor the A1100 series, also ARMv8-A, used ARM Cortex-A57 cores.[4] As of 2018 the product still hasn't been released, with development of ARM architectures continuing but no products planned.[5]
