Doesn't anyone thinks it's a bit weird that GMO's miner B3 is an 7nm architecture, does ~33TH@3300w and the Whatsminer M10 is at 16nm and does ~33TH@2100w?
Not weird at all. GMO tried to be first out of the gate using 7nm and as a result their designs are based on highly immature process technology. As is always the case the results -- suck. Whatsminer simply repeated what they did in the past - wait for the processes behind any given node size to mature and then take advantage of the usually very substantial performance gains seen vs results from 1st gen production or in the case of GMO what was not even that. GMO was touting their proof-of-principle/engineering testing chips as production items.
