ASUS 7970 Matrix Platinum
You have to look a little way down the graph to see our earlier HD7970 tests, which are the VTX and PowerColor for stock and overclock respectively. Of course we don't expect the stock reference card to match up to the stock ASUS thanks to that factory overclock, and the PowerColor was overclocked to around the same level as the ASUS is out the box. In overclocked trim we're looking for it to handily best the Gigabyte Windforce HD7970.
3D Mark Vantage
An inauspicious start for the beast from ASUS. The Matrix Platinum doesn't actually benefit from our extra overclock and when you compare it to the PCS. In fact the PCS just shades it in the P score and it's only in the Extreme preset that the Matrix manages to squeak out a lead.
3D Mark 11
The more shader intensive tests of 3D Mark 11 continue the above result, with the Matrix Platinum not making the most of the clock speeds available, only matching the PowerColor and being beaten handily by the Gigabyte Windforce.
