Helio X30 (MT6799) is a 64-bit deca-core ARM LTE system on a chip designed by MediaTek and launched in early 2017. 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 1.9 GHz, 2.2 GHz, and 2.5 GHz) and supports up to 8 GiB of quad-channel LPDDR4X-3732 memory. This SoC also incorporates a PowerVR GT7400 Plus IGP operating at 800 MHz. The chip has a modem supporting LTE User Equipment (UE) category 10.

Architecture

The Helio X30 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-A73 @ 2.5 GHz
• Performance/Power Balance - 4x Cortex-A53 @ 2.2 GHz
• Power Efficiency - 4x Cortex-A35 @ 1. GHz

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