Qualcomm Kryo[1] is a series of custom or semi-custom ARM-based CPUs included in the Snapdragon line of SoCs. These CPUs implement the ARMv8-A 64-bit instruction set, and serve as the successor to the previous 32-bit Krait CPUs. It is first introduced in Snapdragon 820 (2015) and has been featured in subsequent upper-range Snapdragon SoCs ever since. In 2017, Qualcomm released the Snapdragon 636 and Snapdragon 660, which are the first mid-range Snapdragon SoCs to include Kryo CPUs. In 2018, Kryo marks its debut on an entry-level SoC, the Snapdragon 632.

Kryo

First announced in September 2015 and used in the Snapdragon 820 SoC.[2] 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.

The Kryo in the 820/821 is an in-house custom ARMv8.0-A (AArch64/AArch632) design and not based on an ARM Cortex design.

  • Samsung 14 nm LPP Process
  • Performance core+L2 die size: 2.79mm2[4]

Kryo 2xx Series

The Kryo 2xx Series CPUs is not a derivative of the original Kryo microarchitecture, but rather is a semi-custom design licensed under ARM’s Built on ARM Cortex Technology (BoC) license. The Kryo 2xx Series CPUs is derivative of the ARM's Cortex-A73 for the Performance/Gold cluster and Cortex-A53 for the Efficiency/Silver cluster in a big.LITTLE arrangement.[5]
