MediaTek has recently released the technical “white paper” content for its first true octa core processor, which outlines major differences between its internal components and those used by its competitors.

As pointed out in the report, the most significant aspect of Mediatek’s “true octa core” MT6592 chip lies in its unique internal structure; Rather than using the popular “ARM big.LITTLE” standard adopted by Mediatek’s competitors–which involves a well-known “4+4” architecture pairing the Cortex A7 and Cortex A15 cores with one another–the Taiwanese company has instead chosen to employ eight individual Cortex A7 cores that are each clocked at a frequency of 2Ghz. Whereas the “4+4” structure is able to get only four cores to function at the same time, in Mediatek’s chip all eight individual cores can be tweaked to operate simultaneously.

Another laudable quality of the MT6594 worth mentioning is its power efficiency. When playing HEVC (H265) standard 1080p video, for instance, Mediatek’s 8 core processors are able to save up to 18% energy; As opposed to typical quad core chips, the chip also has the power to enhance a video’s frame rate by up to 20%, making it extremely ideal for media heavy smartphones and tablet devices.

Growing awareness towards MT6594’s merits

As mentioned by techdomino, Mediatek’s MT6592 possesses all the potential and power of a high-end processor despite not being explicitly intended for the high-end market. The chip has reportedly earned a score of “30,000” on AnTuTu, which is notably higher than the score received by Samsung’s Exynos 5 Octo (though slightly behind Qualcomm’s Snapdragon 800).

Originally slated for a late Q4 release, speculation has emerged that the MT6592 chip will be unveiled as early as during late July. The first smartphone or tablet device to actually employ the chip will likely appear in 2014, according to Engadget.
