AMD K12

K12General Info

Launched| Never released
(Planned 2017)
Designed by| AMD
Architecture and classification
Min. feature size| 14 nm FinFET
Instruction set| ARM64 (ARMv8-A)
History
Predecessor| A1100 series

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 Opteron A1100 series, also ARMv8-A, used ARM Cortex-A57 cores.[4] As of 2023 the product has officially been canceled.[5]

The microarchitecture was to focus on high frequency and power efficiency and was to target the dense server, embedded and semi-custom market segments.[6]
