The Rockchip RK3368 was unveiled at CES 2015 as an octa-core CPU replacing the popular RK3288 CPU. The RK3368 includes eight 64-bit cores which can support 4K video running at 60 fps using H.265 decoding and HDMI 2.0. More important than that to so many people, including me, they all can support Android 5.1 Lollipop!
