the leading edge nodes will have a substantial cost premium, but about 1 decade behind leading edge is the cheapest per transistor because when you go back further the increase in transistor size makes them less efficient to manufacture.
- samus 3y agoThe old nodes are cheap because the investment has been fully paid off. There are only running costs and maintenance remaining. However, expanding productions of older nodes will be more expensive, especially if the equipment is not available in bulk anymore. Probably not as expensive as a new node though.
- adgjlsfhk1 3y agoRight. pre EUV, the only reason older nodes were cheap is because you didn't have to build a new fab. Now though, EUV machines are expensive enough that it looks likely that the pre-EUV nodes may remain cheaper pretty much indefinitely. 22/14nm is pretty power efficient, a lot simpler to make.
