You could always dig a bit deeper into the technology and talk about the 90nm fabrication process. This is a drop down from 130nm. That distance is the size of the gap in a transistor. Smaller gaps = lower required voltage and more transistors crammed into one spot.
Or you can talk about Intels hyperthreading. The actual name for the technology advancement is simultaneous multithreading. Dean Tullsen, currently a professor at UCSD, did his thesis on it and is the main contributor to the technology.
Or how about USB 2.0? faster data transfer and such.
