Mediatek Helio P10 and X20 adoption is set to be sky-high for early 2016 but for phones coming later in the year they might receive the 16nm Helio P20.
The Helio P20 is set to come at some point this year, but with Helio X20 manufacture not kicking off until April (ish) don’t expect the P20 in a phone until at least summer.
So a long wait, however when the chipset does arrive it will be built on a 16nm process to ensure a faster more efficient SoC. Although its still very early days yet and the P20 specs haven’t been released we expect Mediatek to give it some sort of combination of A72 and A53 cores (perhaps 6 x A53 and 4 x A72?).
If Mediatek continue at this pace a Helio X30 should be on the cards for the last quarter of 2016.
