Of course this list only serves to answer a few questions as to how the number of transistors have been increasing in cpu's over the years.
The increasing clock speed is also noticeable, but does not really mean that a processor can perform a function faster.
The reducing line width allows more transistors to fit into a smaller space, because the lines that make up the transistors take up less space.
The graphic shows an old 386 uP as a surface mount part, but processors have been using PGA packages for years now.
