The problem with Intel is that they have been missing important deadlines by massive amounts of time. Their 10nm node was slated to arrive almost 5 years ago. It is still far from mature.
TSMC is readying serial production of 5nm (equivalent to Intel 7nm) this year.
I wouldn't plan on seeing a 7nm product from Intel in any volume until 2024, and I wouldn't place money on that as a bet.
