Helio X25 (MT6797T) 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 2.5 GHz) and supports up to 6 GiB of dual-channel LPDDR4X-3200 memory. This SoC also incorporates a Mali-T880 MP4 IGP operating at 850 MHz. The chip has a modem supporting LTE User Equipment (UE) category 6.
The Helio X25 is identical to Helio X20 except for the higher clocked A72 cores and the higher clocked GPU.
Contents
Architecture
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 @ 2.5 GHz
- Performance/Power Balance - 4x Cortex-A53 @ 2 GHz
- Power Efficiency - 4x Cortex-A53 @ 1.55 GHz
The three clusters are designed as a modified big.LITTLE configuration.
