From time to time we stumble upon some truly gifted and patient people here at AnandTech. Some weeks ago I wrote a CPU codename cheatsheet as just something to do in an airport terminal to kill time.

Knowing I was bested, I offered Jarred a chance at writing a pilot for AT, and here it is! Please enjoy the second, extremely thorough CPU Cheatsheet 2.0.
