Samsung's Exynos 7420 SoC is 30 to 35% more power efficient compared to 20nm processors
Preliminary benchmarks proved we're looking at a spectacular chipset that closely matches Qualcomm's cutting-edge processor's performance and is made on an ahead-of-its-time 14nm process. We now learn that the 7420 SoC, which packs an octa-core processor and a Mali-T760 graphics unit, has its power consumption reduced by 30 to 35% percent compared to the previous generation 20nm chipsets, making for a low power, high performance package.
The processor is made on three-dimensional (3D) FinFET transistor technology, used to overcome the limitations of the typical 2D plane (Planar structure). Intel has been using this method for its desktop processors for a while, but Samsung prides itself on being the first to bring this approach to the cramped 14nm mobile application processor die. It will continue using this process in the production of its other semiconductor modules, such as its NAND memory chips, which could lead to smaller chips with increased capacity in the future.
