This is the first Dual ARM Cortex-A7 Harvard Superscalar processor core MT6572 device for axioo smartphone, launched this October with a model name PICOphone 4 GDF. The MT6572 dual-core SoC (System on Chip) platform itself is world’s first dual-core HSPA+ SoC with integrated WiFi, Bluetooth, FM and GPS on a cost effective 4 layer PCB design. It also integrates power efficient dual-core Cortex-A7 CPU sub-system with speed up to 1.2 GHz on 28 nm process technology (same with MT6589 quad-core SoC). Some of you who wants to know what’s the difference this MT6572 with MT6577 and MT6589, may see this Wiki tables comparison.
