Is NanoPi-Fire3 still the King of Clusters?

[LordChuckles]

One of the board members here wrote an article about a 12 node NanoPi-Fire3 cluster.  I found it quite exciting (I don't get out much). It is a couple of years old.

 

 

It seems to be very powerful yet energy efficient. 

 

Is this SBC still the King of clusters?

 

I want to fool around with clusters, cluster software managers and process distributors, and perhaps do some coin mining (if that is feasible).

 

Someone said this board has too little memory for coin mining, that 2gb would be better than 1gb. 

 

Pine have a 7 slot clusterboard which takes their PINE A64 (+) "Single Board Computer powered by Allwinner’s A64 Quad-Core ARM Cortex A53 64-Bit SOC". That chip seems to have Cryptography Extension (SHA and AES instructions). I wonder how it would compete with the Nano pi fire3 for mining.
