Apple proved that Android terminals with quad-core processors are not more powerful than iDevices with dual-core processors, but those from Samsung want supremacy on the market of mobile terminals so develop new processors. These processors will have 4 cores clocked at 1.8 GHz based on the ARM Cortex A15 architecture and 4 cores of 1.2 GHz based on the ARM Cortex A7 architecture. The first 4 cores will have the task of processing all the tasks that require a lot of processor power, and the other 4 will run the operating system under normal use conditions, or when it is blocked.
A 28nm manufacturing process would be used for their production and on February 19 they could be officially presented, but it is not yet known when they will reach mobile terminals. You are probably asking if we need so much processing power in mobile terminals, I say no, especially since Android is just learning to use 4 cores, and the 8 proposed by Samsung will be as useful as the quad-processors were. core on the first implementation in Android.
