MediaTek has just added two new entries in its chipset arsenal, namely Helio X23 and X27. Both are high-end SOCs with upgrades over the existing flagship offering, Helio X20.

The Helio X23 and X27 chips come with better overall performance, video shooting quality and low power usage as cited on MediaTek's own website. Both of these SOCs utilizes the deca-core three cluster architecture made up of two 2 ARM Cortex-A72 cores, 4 ARM Cortex-A53 cores and another 4 ARM Cortex -A53 cores.

Pilot 3.0 heterogeneous computing technology has been used in these chips for bringing precision to task scheduling, core allocation and improvement in both processor performance and power consumption. The operating frequency of Helio X27 has been bumped to 2.6GHz compared to the high-end Helio X25. Even the GPU has received an upgrade to 875MHz. Going by numbers, the company claims an improvement of 20% over the Helio X25 Chipset.

The Helio X23 and X27 ship with upgraded Imagiq image signal processor (ISP), enhancing full-pixel dual-core fast focus (Dual PD) function for better shooting results. This upgrade offers better picture clarity, saturation, exposure control, character performance and large aperture effects, etc. and significantly provides a colorful "lens" life for the smartphone users.

Lastly, both these chips come equipped with Envelope Tracking Module. This feature automatically adjusts the output voltage according to the strength of the output signal of the power amplifier. Hence the heat, as well as power consumption, is kept on a check. Users will experience power savings up to 15% with these chips.
