MediaTek Helio X30 and X22 are deca core processors. MediaTek Helio X22 is basically a faster version of Helio X20 while MediaTek Helio X30 uses a different configuration of the core to improve performance. MediaTek Helio X30 which will have a ARM Mali-T880 graphics chip will have support of up to 4GB RAM and eMMC 5.1 storage. It consists of 4 core ARM Cortex-A72 2.5 GHz; 2-core ARM Cortex-A72 at 2 GHz; 2 core ARM Cortex -A53 1.5 GHz and 2-core ARM Cortex-A53 at 1 GHz.
MediaTek Helio X20 is a deca-core chip with ARM Mali T800 graphics and support for 4G-LTE, WiFi 802.11ac networks. It comes with a ARM Cortex-M4 co-processor for speech recognition. It consists of two core ARM Cortex-A72 2.5 GHz; 4-core ARM Cortex-A53 at 2 GHz and 4-core ARM Cortex-A53 at 1.4 GHz.
MediaTek Helio X22 is similar to Helio X20 but operates at a higher clock frequency. Phone and tablet OEMs will be able to purchase them in the begining of 2016. Helio X-Series combine high power with high efficiency to prolong the battery life. But what makes MediaTek Helio X30 and X22 different from most of the SoC on the market is the number of cores and their organization.
