Kryo is a microarchitecture designed by Qualcomm implementing the ARMv8-A 64-bit instruction set, and serves as the successor to the old 32-bit Krait core. It was announced in September 2015 and first used in the Snapdragon 820 SoC, which is manufactured in Samsung's 14 nm FinFET process. The Kryo cores can be used in both parts of the big.LITTLE configuration, where two dual-core clusters (in the case of Snapdragon 820 and 821) run at different clock frequency, similar to how both Cortex-A53 clusters work in the Snapdragon 615.
A new generation of this microarchitecture, named Kryo 280, was announced along with the Snapdragon 835 chipset in November 2016.
