Once again the Dailytech dish up the goods for us as they manage to obtain some more definitive specifications on AMD/ATIs upcoming R600 monster.

In the form of the "Radeon X2900 XTX", these cards will apparently kick off on March 30 with plans for AMD to make sure that they become available in stores on launch day. The full blown variant will sport 1GB of GDDR4 based memory with a cheaper offering to soon follow with 512MB of GDDR3.

Further info here.

Late yesterday DailyTech was briefed on the final details for the upcoming R600 retail specifications, just in time for everyone to go on vacation for Chinese New Year. AMD has briefed its board partners on the specifications that will appear on the marketing material for the card launches.

AMD's guidance claims R600 will feature 700 million transistors. By comparison, the Radeon X1900 series R580 GPU incorporated 384 million transistors into its design; the half-generation before that, R520, only featured 320 million.
