To be precise, Moore’s Law says the number of transistors per unit cost doubles (every two years). https://newsroom.intel.com/wp-content/uploads/sites/11/2018/...

A lot of the new processes have not had the same cost reductions. Also, some increase in transistor count is due to physically larger chips. Also, you have “Epyc Rome” on that graph, which actually isn’t a single chip but uses chiplets.
