This chip will be named Radeon X1800 GTO. It's a X1900 with lower clockspeeds, 256MB memory and a couple of features disabled.
The early March timeframe suggests the part will debut at CeBIT or just before. The show, which kicks off on March 9 in Hannover, Germany, is also expected to play host to the launch of Nvidia's next-generation part, the GeForce 7900 GTX.
It should be priced at $279.
Additionally, there's also a rumour that ATI's 80nm R600 will arrive by October.
