EEClock for clock, this is the same card as the GTX 280. There is no need to have tests to show this since the Nvidia documentation explains it in plain English. The entire point of this card is to showcase the 55nm manufacturing process with a card that can clock well while getting by with less power consumption.
I have the vanilla version (01G-P3-1280-AR) but riva tuner reports the clocks as 621/1350/2268 which are NOT what they are supposed to be. But doing a little research these clocks match the Superclocked version (01G-P3-1282-AR). WTF!Biff...is your 280 vanilla or other Edition?
