One can debate whether TSMC 10nm is closer to Intel 14nm or 10nm, but from Apple's, Qualcomm, or Nvidia, all they can be are happy customers to see TSMC produce each generation like clock work and with each one get PPAC ( Power, Performance, Area, and cost ) improvement! It matters less to them whether TSMC is behind or ahead, all that matters is they deliver each generation on schedule, ramp it, and produce meaningful PPAC. Each new generation if the design guys get it right will over value to the customers to upgrade.
Intel's position is much more precarious now that we hear we have Kabby and Coffee both on 14nm, that will be FOUR generations on the same process node, thus minimum PPAC, if anything more and more expensive as silicon die won't be shrinking and no intrinsic power or performance improvement either. From all external appearances it looks like Intel the keep of Moore's Law has failed and that TSMC is now the keeper of Moore.
Sorry BK gets more than an F for letting this happen on his watch! He has end of Moore, Layoffs/ACT, and silly initiatives in modems, tablets, mobile, 5G and memory to his name!
Search the web the other posters are correct! TSMC has 10nm up and risk production coming and 7nm is yielding and already have working ARM cores out on it and by all reports are on schedule.
You all can draw your own conclusions on state of things!
