Today Monday morning, some information leaked about the Qualcomm Snapdragon 818 SoC, which also will feature a deca-core CPU.
This chip offers four low power cores (1.2GHz Cortex-A53), two mid-range cores (1.6GHz Cortex-A53) and four high-power cores (2.0GHz-Cortex A72). The Snapdragon 818 chipset is said to come with the Adreno 532 GPU and supports LPDDR4 RAM. It is built to handle LTE Cat-10 speeds and is produced using the 20nm process.
We take it as a rumor, until Qualcomm give us an official announcement.
