The Newest 64-bit Intel® Atom™ Processor Z3580

The 64-bit Intel® Atom™ Super Quad-Core 22nm processor inside ZenFone 2 carefully balances brilliant performance and superb power efficiency, empowered by the sophisticated Silvermont architecture.

Intel® Exclusive 3D
Tri-Gate Transistor

First introduced by Intel® in its desktop-class Ivy Bridge processors, ZenFone 2 employs the very same 22nm technology in its 64-bit processor. The Tri-Gate transistors have almost three times (3X) more surface area as compared to planar transistors, enabling more electrons to flow when it in the ‘on' state. It also improves the transistor switching performance which increases the computing performance and decrease the power leakage.
