The new Octa Core Mediatek Processor MT6592 or MTK6592

The last article about the company Mediatek and their processors I wrote about was in 2012, the link HERE
The time has come to update that article.
Here is the lineup of the Mediatek soc processors.
MTK6573 Single Core Cortex A8
MTK6575 Single Core Cortex A9
MTK6577 Dual Core Cortex A9
MTK6572 Dual Core Cortex A7 ( Newer lower cost, higher speed version of the MTK6577 )
MTK6589 Quad Core Cortex A7 ( Original name MTK6588.  T version is 300mhz faster )
MTK6582 Quad Core Cortex A7 ( Newer lower cost verson of the MTK6589 but 720p screen support only)
MTK6592 Octa Core Cortex A7

The MTK6592 is a big step up from the MTK6589 and MK6582 – built on a 28nm HPM process, the two processor sports a higher clock on their ARM Cortex-A7 CPUs, support for LPDDR3 RAM and an upgraded GPU prowess, thanks to quad-core Mali450s that also feature a higher clock than their predecessors.

Samsung's Exynos 5 series also features an Octa core processor but works in the big.LITTLE configuration. For the benefit of those who dont know what big.LITTLE is, here's the explaination in simple terms:
Big.LITTLE processing achieves high performance and low power consumption by pairing the best of the high performance Cortex-A15 MP Core and ultra efficient Cortex-A7 processors.
Big.LITTLE processing allows devices to seamlessly select the right processor for the right task, based on performance requirements. Importantly, this dynamic selection is transparent to the application software or middleware running on the processors.
In the Exynos 5 Octa core processor, there is a set of quad Cortex A15 for heavy duty processing and another set of quad core A7 processor for lightweight use. Only one set will be active at any one time depending on the application and usage. So in principal, it would still be quad core processing within an Octa Core configuration.

HOWEVER, the MTK6592 does not use ARM's big.LITTLE solution. Instead it implements eight A7 cores delivering true octa-core processing.  AnTuTu benchmark scores go up to 28,000, which puts the this SoC between the Qualcomm Snapdragon 600 and Snapdragon 800 in terms of performance...but without the bigger price tag.

The MTK6592 was launched late last year in November 2013 and now in March 2014, countless phones utilizing the MTK6592 has appeared everywhere. These phones are all in the $200-$300 price bracket. The new low cost quad core processor MTK6582 and the older MTK6589 still has a lot of grunt left and will make very good lower cost alternatives. I have been using two MTK6589 phones for the past 9 months and they do everything I i throw at them effortlessly. But having the MTK6592 Octa Cores in your phone gives you bragging rights.
