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,^[1] 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.
