Template:mpu Helio X20 (MT6797) is a 64-bit deca-core ARM LTE system on a chip designed by MediaTek and introduced in early 2015. 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 Mali-T800 MP4 IGP operating at 780 MHz. The chip has a modem supporting LTE User Equipment (UE) category 6.

Architecture

The Helio X20 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 Cortex-A72 @ 2.5 GHz
• Performance/Power Balance - 4x Cortex-A53 @ 2 GHz
• Power Efficiency - 4x Cortex-A53 @ 1.4 GHz
