With Globalfoundry dead and almost everyone else abandoned plans to make 7nm, TMSC is only game in town especially after intel and Samsung stumble.
Intel 10nm would be mass produced in 2021 and 7nm would be mass produced in 2023 which means intel is out of the competition of most advanced chips even if we assumed no further delay. Samsung is having a yield problem for its 7nm and losing a lot of orders for 5nm due to the yield issue. Samsung is definitely behind TSMC now but trying to pretend it is still in the game.
TSMC is unstoppable right now. Its 5nm is on time and 3nm looks like would also be on time. That means China only needs to catch up with TSMC. SMIC is developing 7nm and should be ready in 2021. Although without EUV and the threat of sanctions would probably set back China a few years.
