(unofficial) First tests of Radeon 6870

The title says it all. First unofficial tests of Radeon 6870. I have to say that the 3DMark Vantage score is impressive. 6870 beats the GTX 480 (or other name very loud radiator :D)
We have also some specifications of the card so
Clock: 850 mhz
Memory: 256 bit of 6400 mhz GDDR5 memory 204,8 GB/s data rate transfer.
Rest of the specifications are mystery :) for now of course.
I am very interested how powerful will the 6870 be.
For now we have to w8 for the official results.
