Hi, sorry for my English. I live in a place where the Electric power is very expensive. Every activity is not profitable other than the trading. I noticed that Linux can be well configured to create clusters. Create cluster will increase the power of a mining station. If I create a cluster with very little credit card boards I could get mining power with a low cost. A very simple CPU as H5 (OrangePi) has 4 cores. And it is not ended: it has a hexa core Mali450 GPU! I suppouse that it should be good to try to mine with these cores. And it supports OpenCL and every core is a 64bit core. ARM processors can work very very well with ARMBIAN Distro!! It is fantastic! I can have a very BIG computer in only one credit card. It means that I can create a cluster with twenty micro PC. Why miners ingore this? It should be a miner software to get this usefull power. Please can anyone collaborate? Thanks.

There are two fundamental issues with those SoC, the first one is the market share, You see, every one or almost every one has a computer with X64-X86, PC components are available everywhere and can be adapted or scaled by almost anyone.
The other one is in terms of computational power even from a brute flops perspective these SoC are getting closer to the average CPU GPU, they still not there especially if you compare apples to apples.
So like you've mentioned before to get anything decent you need to build a proper cluster of those, but when you do that you you are eliminating the efficiency factor and it becomes quite expensive.

So to resume I feel like there is a huge potential with these chip, but they should be used to mine something that goes with their strengths and not go with a general mining machine, because you cannot beat something that is already available everywhere without having a clear advantage in anything (power consumption is not if the cost to build a,d effort or the performance is not there )
