If this report from FUDZilla is correct, AMD won't be able to release the ATI RV630 and RV610 GPUs alongside with the Radeon X2900 series (R600) in May:
This is just one in a series of delays at ATI so we are not really surprised. RV630 and RV610 are 65 nanometres and TSMC still have some problems ramping up the production volume and yields. It is now certain that the mainstream and entry level DX 10 parts from ATI won't arrive until June, if not later.
We've also learned that Dell, HP, FSC and other big OEM's have ordered a bunch of these cards and this will also cause a delay in the retail and etail channels. We wonder what exactly ATI's partners are going to sell as ATI has delayed every single chip in the last six+ months.
