Snapdragon 835's second cluster is a Cortex A53
 

4x Kryo 280 and 4x Cortex A53

Ever since Fudzilla received confirmation that the Snapdragon 835 will be an eight-core 10nm processor, we wondered about the power-efficient cluster. Now we can confirm that one performance cluster is made from four Kryo 280 cores and the second is powered by Cortex A53 cores.

Kryo 280 is an upgraded Kryo 200 core manufactured at 10nm. According to Qualcomm the chip requires some 25 percent less power compared to the Kyro 200 based Snapdragon 820. The fact that the new SoC has eight cores, hte power cluster will dramatically help the battery life.

The Kryo 280 part will do the heavy lifting with clocks up to 2.45 GHz while the Cortex A53 part will help the SoC preserve some power in the less performance intensive tasks.
