Mediatek has just announced its newest chipset for the mid-range market here at MWC 2015. It's called the MT6753, and it's a 1.5GHz ARM Cortex-A53 64-bit processor with support for WorldMode modem capability.
The ThL T200 is a large and powerful phone. At 6 inches some would call it a "Phablet". Not only is this device big on the outside, it is also big on the inside. At its heart is a MediaTek octa-core processor, 2GB of RAM, and 32GB of internal storage, plus some nice extras like NFC.
