This SoC incorporates 3 independent clusters of cores (called "Tri-Cluster Technology" by MediaTek) operating at varying degrees of performance designed for certain workloads (operating at 1.4 GHz, 2 GHz, and 2.5 GHz) and supports dual-channel LPDDR3-933. 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. |
