Qualcomm Krait is an ARM-based central processing unit included in the Snapdragon S4 and earlier models of Snapdragon 400/600/800 series SoCs. It was introduced in 2012 as a successor to the Scorpion CPU and although it has architectural similarities, Krait is not a Cortex-A15 core, but it was designed in-house.[1] In 2015, Krait was superseded by the 64-bit Kryo architecture, first introduced in Snapdragon 820 SoC.
