Some of you may have heard rumours that MediaTek was working on MT6575T, an improved version of MT6575, integrating a dual-core ARM Cortex™-A9 processor.
It is now being said that the new chipset will be named MT6577, although further informations such as the integrated GPU are not yet known (better to wait for an official MediaTek announcement).
According to several sources (such as www.m44.com.cn) there are already engineering samples floating around. From a series of third-party benchmarks, it's claimed that this new MediaTek chipset outperforms Qualcomm’s Snapdragon MSM8255, being very close to MSM8255T's performance.
MediaTek's MT6577 is expected to enter into mass production already this month.
