And anyone claiming the manufacturing process is giving intel headache needs to in fact stop pretending they know what they're talking about. Intel has in fact stated they have invested so much into architecture that they will quickly instead of utlizing 7nm node to it's full potential move from 7nm to 5nm as they believe even 7nm is an antiquated fab node.
They are ready to make the jump in rapid succession from 7nm to 5nm as they have utilized a far less impressive 14nm architectures for so long it's more pertinent to move to an even smaller fab node process. AND again, wrong if you do not believe intel CPU's will trounce AMD cpu's when the mere fabrication shrink will yield 133% more performance with the current superior architectures. The gent insisting otherwise is out of his league.
