'''Helio X30''' is a {{arch|64}} [[deca-core]] [[ARM]] [[LTE]] system on a chip designed by [[MediaTek]] and set to be launched in early [[2017]]. This SoC incorporates 3 independent clusters of cores (called "Tri-Cluster" by MediaTek) operating at varying degrees of performance designed for certain workloads (operating at 2 GHz, 2.2 GHz, and 2.8 GHz) and supports dual-channel LPDDR3-1866. This SoC also incorporates a {{imgtec|PowerVR GT7400}} [[IGP]] operating at 870 MHz. The chip has a modem supporting [[LTE]] User Equipment (UE) category 10.

== Architecture ==
The Helio X30 is designed is composed of 3 individual clusters of CPU cores depending on the level of performance required by the active applications.

* Extreme Performance - 2x {{armh|Cortex-A73|l=arch}} @ 2.8 GHz
* Performance/Power Balance - 4x {{armh|Cortex-A53|l=arch}} @ 2.2 GHz
* Power Efficiency - 4x {{armh|Cortex-A53|l=arch}} @ 2 GHz

The three clusters are designed as a modified {{armh|big.LITTLE}} configuration.
