Predecessor Krait

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) run at different clock frequency, similar to how both Cortex-A53 clusters work in the Snapdragon 615.

Overview

  • Pipelined processor with an out-of-order superscalar execution pipeline
  • 32 KiB + 32 KiB L1 cache[2]
  • 512 KiB (low-frequency cores) + 1 MiB (high-frequency cores) L2 cache
  • Core performance: 6.3 DMIPS/MHz
