More info about ATI's upcoming GPUs were revealed:
The R600, ATI's ultra-high-end Radeon X1950 successor, has a production date scheduled for February 2007. The card will launch at or around the Cebit 2007 convention in mid-March. Shipments will follow shortly after.
Our latest roadmaps indicate R600 will support unified shaders and GDDR4 or GDDR3 memory. GDDR3 versions of the card running revision "A12" silicon appear to be making rounds in the blogsphere, and select press can even take a sneak peak of the card under embargo here at CES. The final silicon for R600 will be "A13."
A GDDR4 version of the card will be the flagship launch product. Clock frequencies on any R600 card have not been set officially yet, and will not appear on marketing material until just a few weeks before the launch.
The R610 is the entry-level version and the R630 will possibly be the mid-range GPU.
