Helio X20 (MT6797) 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 2.1 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.
The Helio X20 is identical to Helio X25 except for the lower clocked A72 cores and the lower clocked GPU.
Contents
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.
- Extreme Performance - 2x Cortex-A72 @ 2.3 GHz
- Performance/Power Balance - 4x Cortex-A53 @ 1.85 GHz
- Power Efficiency - 4x Cortex-A53 @ 1.4 GHz
The three clusters are designed as a modified big.LITTLE configuration.
