Mikri Zhang, co-founder of the Chinese mining company Bitmain, has just announced the start of the sales of crypto mining devices based on 5nm chips.
According to WuBlockchain, the miners must be paid before they are shipped, while the estimated shipment date is January 2021.
WuBlockchain has reported Zhang cannot make devices based on 7nm and 16nm chips, which is the reason why it has decided to use 5nm chips. As a result, even though the energy efficiency of these miners could reach 25-30J/T, serious problems might arise and the manufacturing capacity cannot be guaranteed.
Bitmain co-founder Jihan Wu, who is fighting against Zhang for the control of the company, has said 5nm chips are still in the design stage and will not be available on the market in the short term. Wu has said:
"In order to prevent customers from being deceived, Bitmain Group hereby made this declaration. 5nm is the latest chip production process, and a large number of new technologies applied need to have a new architecture to match. Bitmain’s first-generation experimental 5nm product BM1360 chip is only used for internal verification to solve performance and reliability problems caused by new processes, technologies, and architectures. There is no plan to release or sell 5nm products to the market for now."
