Rumors leak about R600 lineup, memory specs

The closer ATI's R600 graphics cards get to release, the more rumors slowly seep out about their specifications. This time, the folks at The Inquirer have come upon on a host of information about ATI's upcoming DirectX 10 lineup. They say four R600 variants will be available, and that their model names will unsurprisingly be part of a new Radeon X2000 series.

The top-of-the-line part will have an XTX suffix, a 12-inch-long board, 1GB of GDDR4 memory, and a 512-bit memory bus. A slower model with an XT suffix will reduce the card length to 9" and will be available with either 1GB or 512MB of GDDR4 RAM. The remaining two models will have XL and GT suffices with a similar 9" PCB length, and the GT part will use GDDR3 memory instead of GDDR4. Interestingly, The Inq says the slower models will be equipped with a single-slot cooler. Still, the XT, XL, and GT cards will reportedly all draw power through a new 8-pin PCI Express power connector, and the XTX flavor will require two 6-pin connectors—just like Nvidia's GeForce 8800 GTX.
