I doubt they leap frog TSMC. 18A will come out around the same time as N2. I have more confidence that TSMc’s N2 will perform better and be in far higher volume and yield rate.
20A is sort of Intel’s first foray. 18A is really their serious node.
If you think Intel has a chance to leap TSMC, it will come at the 14A node but you have to bet that TSMC is wrong to stay with low NA.
