Again, as we mentioned in the introduction, to get a good run down on what exactly we're looking at here we highly recommend that you take the time to head over to our Technical Preview that covers all this information and more.

 

Specifications

 

The Sapphire card like you would expect carries with it just the reference clocks; of course there are two positions our "Dual BIOS" switch can be placed in which carries with it two different speeds.

In "Position 2" (the shipping position) you can see above our clocks come in at 830MHz on the core and 5500MHz QDR on the memory. Below, though, you can see the card in "Position 1" which keeps the memory at the same 5500MHz QDR, but increases the core to 880MHz.

Again, though, if you want to find out more about this features we really recommend that you take the time to check out our Technical Preview.
