The leadership has definitely shifted to Taiwan. TSMC 7nm is roughly equivalently to intel 10nm. At leastTSMC first version of 7nm. But TSMC is now well in to ramping their 2nd/3rd iterations of 7nm. And ramping 5nm soon-ish, now this news on 3nm.And Intel has stumbled badly on 10nm, they are now years behind where they wanted to be. Intel are still launching new high end skus on 14nm through 2020. They are shipping 10nm in some volume, but with evident problems still on frequency binning and yield.
