The Kirin 655 octa-core processor uses a 16nm process with four 2.1GHz A53 and four 1.7GHz A51 i5 coprocessors, while the GPU uses the Mali MP2 T830 and supports full NetCom.
The Kirin 620 is designed with a 64-bit octa-core Cortex-A53 architecture, built on a 28nm process, with a maximum speed of 1.2GHz, a Mali450MP4 GPU, LPDDDR3 memory, a maximum 13MP camera, and 1080p 30Hz video encoding\/decoding. In addition, the SOC also integrates a baseband chip to support the LTE Cat.4 specification up to 150Mbps, including GSM\/TD-SCDMA\/WCDMA\/TD-LTE\/LTE FDD.
