Processor and memory
The hardware basis is already the beginning of 2016 published and designed mainly for smartphones MediaTek Helio X20 system-on-chip, The CPU of the SoC consists of 10 processor coreswhich turn into 3 cluster divide. The High Performance Cluster Composed of 2x Cortex A72 cores that clock up to 2.3 GHz. Of the performance cluster consists of 4x Cortex A53 cores, which in turn clock up to 1.85 GHz. There is also one for efficient work Power Save Cluster with 4x Cortex A53 cores and a 1.4 GHz clock rate. The SoC GPU is one ARM Mali-T880 MP4 GPUthat clocks up to 780 MHz.
