There's a new player in the quad-core SoC game and it's called the MT6589. MediaTek announced today that it's launching the world's first quad-core Cortex-A7 SoC and gave us the opportunity to take it for a spin -- in prototype form, of course. The MT6589, which includes the aforementioned quad-core Cortex A7 1GHz+ CPU, also features a PowerVR Series5XT GPU, high-performance multimedia support (13MP / 3D camera, 1080p video and display, Miracast) and a built-in 42Mbps HSPA+ / TD-SCDMA-capable dual-SIM dual-active radio. By combining competitive performance with high thermal efficiency and low power consumption in an affordable package, MediaTek's new chip is well suited for a wide-range of smartphones and tablets running Jelly Bean and beyond. The MT6589 will be available in devices starting Q1 2013. Check out the gallery below and hit the break for our impressions and benchmarks plus MediaTek's videos and PR.
