Good point, but Moore`s Law says that the TRANSISTOR count doubles every two years, not that we are getting more cores. Cores are added with the use of more silicon and making the dies bigger. Of course it is not that simple.
BUT, during the solar eclipse, Intel said that they can pack 100 million transistors in 1 square mm. I don`t know what was the max number two years ago, but i don`t think it was anywhere near the current number.
