Sony may launch cheap quad-core Android smartphones in 2013, testing chips by MediaTek

When it comes to the chips used in today's smartphones, MediaTek isn't the first name that springs to mind. That's because its products are used primarily in low-cost handsets made by lesser-known Chinese companies, while the big boys go with silicon provided by Qualcomm, NVIDIA, ST Ericsson and the likes.
The MediaTek MT6589 is made using a 28nm manufacturing process and uses Cortex A7 processor cores. It can be clocked at up to 1.2GHz and supports LPDDR2 RAM. The PowerVR SGX544 GPU should be capable of handling 720 by 1280 pixel displays. Camera modules of up to 13 megapixels are supported, along with 1080p video recording.
