Samsung Electronics has officially unveiled the 'Exynos 7 Octa' mobile application process (AP), which offers improved data processing performance and is the company's first AP to supports 64 bit. The chip already powers the Galaxy Note 4 - at least in some regions.

It has an octa-core structure comprised of four high-performance big cores (ARM Cortex – A57) and four low-power little cores (ARM Cortex – A53). It uses 20nm HKMG process technology as well as advanced mobile image compression (MIC) technology to deliver the power efficiency.

The Exynos 7 Octa implements big.LITTLE Heterogeneous Multi Processing (HMP) and provides a 57% CPU performance increase from the previous generation Exynos, Exynos 5 Octa. With the ARM Mali-T760 installed as a graphic processing unit (GPU), the graphic processing performance of Exynos 7 Octa has been improved by 74%.

Capable of ultra high-definition (UHD) photo and video filming and playback, Exynos 7 Octa also supports high-end applications, such as 3D game, face and iris scan and augmented reality. In addition, it is mounted with a dual-image signal processor (ISP), and thus can take videos by concurrently using the rear camera of 16 million pixels and the front camera of 5 million pixels.

Should an iris recognition function be expected in the Galaxy S6?
