Processor and memory

The chip is a further development of the Snapdragon 2018 chip presented in May 710 and is intended to close the performance gap between the current Snapdragon 600 and 800 series. Compared to the Snapdragon 710, the performance has been increased by 10%. A total of 8 processor cores are divided into a performance cluster with 2 Kryo 360 Gold cores (2.3 GHz) and an energy-saving cluster consisting of 6 Kryo 360 Silver cores (1.7 GHz). The graphics unit is an Adreno 616 GPU, with which current mobile games can be played smoothly. The SoC achieved just over 180.000 points in the AnTuTu benchmark.

In terms of memory, the smartphone uses a 6GB LPDDR4X 1866 MHz dual-channel main memory and an optional 64GB or 128GB UFS2.1 data memory. A memory expansion using a microSD memory card is not possible.
