1st and foremost, TSMC is open to any contract work. however, as i've said and some people refuse to hear or acknowledge, 7nm production is restricted to those companies that invested in the infrastructure of the new fab. it's really very simple. the so-called "increased costs" associated with the new node are no different than the costs associated with other new nodes at other times adjusted for inflation. having something "new" for christmas is never a priority for either AMD or Nvidia as there have been many christmases with nothing new, like last year and the year before. it is about herding cats (i.e. design validation, fab prep, fab shipping, AIB's getting gpus and shipping AIB's, etc). when the job is done well (i.e. Pascal), the game developers are under NDA for months with ES cards, the product is widely available upon release (or shortly thereafter), and the final product is an improvement, usually a marked improvement. that is not Turing. as for AMD going all in on 7nm, from their position in the market why the hell not? they are not going to catch Nvidia at it's own game, so they are playing another game...called leapfrog. and it's scaring the hell out of Nvidia and Intel. personally i have no axe to grind, i'm invested in Nvidia, Intel, TSMC, and AMD. so i get copies of the quarterlies that i actually read, i'm in the tech sector myself, and i live in Silicon Valley less than 10 minutes away from AMD, Nvidia, and Intel...and i've been following these companies (or their predecessors) since the 1980's.
