A news article from VR-Zone claims ATI has redesigned the R600 card. The new version will be smaller than the original 12-inch long reference design and will also have better cooling.
The Inquirer has recently reported ATI has already produced some first R600 cards that are clocked lower to send out to game developers for debugging and optimizing their games for R600.
The R600 card we seen will conform to the new PCI-SIG graphics spec of delivering 225/300W power for high-end graphics cards. Therefore it will have a new 2x4 pin connector for additional power on top of the current 6-pin connector.
