Helio X20 M (MT6797M) is a 64-bit deca-core ARM LTE system on a chip designed by MediaTek and introduced in early 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 1.4 GHz, 1.85 GHz, and 2 GHz) and supports up to 6 GiB of dual-channel LPDDR3-1866 memory. 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[edit]

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.

The three clusters are designed as a modified big.LITTLE configuration.
