And belive me - for this SoC we can wait.
Next top model from MediaTek will have two Cortex-A73 (Artemis) cores with (most likely) 2.8GHz clocks, four Cortex-A53 (2.2GHz) and four Cortex-A35 (2GHz) and also PoWerVR GPU what gives quite nice package.
And it's not all, processors will be in 10nm technology what will lessen energy usage and heat emission.
For premiere of first devices with this SoC we will wait untill second half of 2017 but as I wrote earlier - we may wait for this goods.
