BAD HARDWARE WEEK

Just a switching performance optimization.
The 16nm node represents TSMC's first use of FinFETs, a.k.a. vertical transistors. Indeed, this node basically just adds FinFETs to the existing 20nm process, thus it provides almost no gain in packing in more transistors per area of die, although it does offer benefits in lower power or higher performance.

99% BAD HARDWARE WEEK: 16nm is known in expert terminology as half node. And it will be at disposal in 2015, at best scenario. 14nm? Will it offer full scale advantage we will only see. Just as nobody knows will Intel offer scaling down 22nm process at 14nm at all. All the rest is INTELLIGENT MARKETING :)
