"The G80 A3 chip comes packed with the same set as the older A2 revision but unlike the older one, the new A3 is more power efficient. The same can be said about the Samsung GDDR3 chips too which are pretty unique. The K4J52324QE-BJ08 series uses 0.8ns chips and that can come in handy since they can work at higher clockspeeds than the classical 1ns used on the standard 8800."
