Helio X23 (MT6797D) 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 1.4 GHz, 1.85 GHz, and 2.3 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.
The Helio X23 is identical to Helio X20 with the additional support for dual-camera setup and MiraVision's EnergySmart Screen technology.
Architecture
The Helio X23 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.
