Helio X27 (MT6797X) is a 64-bit 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 Mali-T800 MP4 IGP operating at 780 MHz. The chip has a modem supporting LTE User Equipment (UE) category 6.

The Helio X27 is identical to Helio X20 with higher CPU clocks speed and higher GPU clock speed. Additionally this model also supports for dual-camera setup and MiraVision's EnergySmart Screen technology.

Architecture[edit]

The Helio X27 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.
