Samsung officially launches in the race for 64-bit mobile processors with a new family of Exynos 7 Octa-based cores of ARM Cortex-A53 and A57 configuration big.LITTLE.
If Qualcomm responded immediately to the announcement of the Apple A7 64-bit processor with the SoC Snapdragon 410 quad core 64-bit on the market, the Samsung group remained silent on the subject and merely continued to operate on platforms of 32-Bit octa-core.
The first sign in the direction of 64-bit came from octa-core platform called Exynos 5433 which proved to be equipped with quad-core ARM Cortex-A53 and quad-core ARM Cortex-A57, which is present in the Galaxy Note 4 phablet presented last September.
The Korean giant had not detailed the processor or its name. It has to do with the Exynos 7 Octa renaming first processor of a line using 64-bit ARM Cortex-A53 cores and A57 ARM big.LITTLE HMP configuration (Heterogeneous Multi Processing).
Note however that SamMobile indicates that A57 cores are not activated in 64-bit, which should not prevent an update to Android 5.0 Lollipop exploit to finer hardware configuration of Galaxy Note 4.
Samsung announces 57% increased compared to Exynos 5 performance and etching 20 nm HKMG also improves energy consumption. The SoC is capable of supporting the WQHD and WQXGA resolutions and can be used to stream video in UHD/4K on the big screen.
With two chip signal processing, the Exynos 7 Octa can even record two videos in high resolution cameras simultaneously from the front and back of a smartphone. The graphic part is represented by an ARM Mali T-760 GPU.
