'''Helio X27''' ('''MT6797X''') is a {{arch|64}} [[deca-core]] [[ARM]] [[LTE]] system on a chip designed by [[MediaTek]] and introduced in late [[2016]]. 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 1.6 GHz, 2 GHz, and 2.6 GHz) and supports up to 4 GiB of dual-channel LPDDR3-1600 memory. This SoC also incorporates a {{armh|Mali-T800 MP4}} [[IGP]] operating at 780 MHz. The chip has a modem supporting [[LTE]] User Equipment (UE) category 6.
