Which Nvidia cards are "Kepler"

I was thinking about G-sync and I remembered it only works on Kepler cards. Which cards are Kepler? I believe it is 600s and newer but I may be wrong. 

anything that starts with a 6 or 7

thought only the 680 was kepler? oh well you learn something every day :D

all GPUs from the 645 (OEM edition) and up are kepler, this includes the current 700 series.
