I'm very curious to see what happens to Intel. When the TSMC Arizona plant comes online in 2024 or sooner there doesn't seem to be much left for it to do that AMD and others are already doing more effectively. Perhaps that's too much an oversimplification, however it seems to be the sum of the various parts given as others have said here and elsewhere (and was my experience too), the performance of Intel hasn't changed much in about 10 years.
