MediaTek, the well known budget mobile SoC maker, whose products power almost 90% of all high-end Chinese Smartphones (and some top-branded devices as well, such as the Sony Xperia C), is working on two new chipsets. One of them is a quad-core part, while the other is the world's first true octa-core mobile SoC. And today, we have the full specifications of both these chipsets, courtesy of a Chinese Weibo user.

　　As the table clearly reads, the quad-core MT6588 chipset is an upgrade over the MT6589, and is also said to be pin-to-pin compatible with the same. It features four ARM Cortex A7 cores clocked at 1.7 GHz (up from 1.5 GHz in the MT6589T), supports faster 666 MHz LPDDR3 RAM as well as a new ARM Mali450-MP4 (quad-core) GPU clocked at 600 MHz, which replaces the original PowerVR SGX544.

　　Moving on, the octa-core MT6592 will end up with a clock speed lying in the range of 1.7 GHz to 2 GHz for all eight of its ARM Cortex A7 CPU cores. Also, it features the same mid-range ARM Mali450 in quad-core configuration. However, the GPU clock speed has been bumped up by an additional 100 MHz, to 700 MHz for the octa-core chipset.

　　Both new chips are rumored to be officially announced by MediaTek on November 20th, at an event to be held in Shenzen, China.
