Several sites have reported the launch of the Radeon HD 4730 - a gap fill for the lack of HD 4770s. AMD has confirmed the launch and given us the details on the availability of its star card. It admits having had problems fullfulling the “enthusiastic” market demand for the HD 4770. In particular it cites technical problems with TSMC’s 40 nm fabrication process. AMD says that “initial demand” was satisfied but that supply is still not keeping up with it’s objectives. So as to fill the gap, ATI/AMD has created the Radeon HD 4730 which is simply an HD 4830 with GDDR5 memory and a 128 bit bus (instead of GDDR3 with a 256 bit bus). So instead of a card based on the RV740 and engraved at 40 nm we have an RV770LE engraved at 55 nm.
