Thank you for letting me know you are the first to reach the limit of 28nm Sha256 engineering.
Thank you again.
RockerBox is certainly not the limit of 28nm SHA256 engineering.
PickAxe our 3rd gen is also 28nm. The fact that we're using exactly the same process means one less production risk for us. We gained a lot from the issue we encountered with the first wafers lots of RockerBox.
I believe that there is still a lot room for improvement.
Yes... the 3rd gen... hmmmm speed less power.... dreams of BTC at 1000$ plus.
