I got the information below about ATi Radeon X800 GT.

Well, rumor time. The Chinese website GZeasy says that ATi is about to launch a new graphics card, namely the Radeon x800 GT. Of course as the name suggest it is going to compete with the truly wonderful nVIDIA GeForce 6800 GT. Basically what you can expect is a x800 XT yet clocked slower. the same dynamics as the 6800 Ultra has over the GT, except for Shader model 3 support that is. Core frequency should be 425 MHz and the product will have 256MB GDDR3 memory at 900 MHz, of course it'll have 16 pixel pipelines.

This product remains speculation yet would make sense as ATi does not have a product thet closes the gap with the competition between the x800 Pro and the XT. I also doubt a little that the proiduct will actuially be called GT.
