To give you an idea, the #2 best seller of laptops right now on Amazon has the N3160, which is an almost 4 year old Atom.
I doubt Samsing's 14 nm node is expensive at all and Samsung does have a fab in Austin.
They'd have to port the design to Samsung's node. It's a longshot for anything other than Atom of course, but they might not have any choice if they aren't willing to cede the market but need the wafers for Cooper.Intel has 16 fabs. You honestly think they're going to pay out the nose to a third party or convert more of their fabs into modern ones to handle the load all the way into 2023? If you seriously think Intel would rely on another company to make their 14nm, I've got a bridge to sell you.
