References found in the new ATI Catalyst 9.1 driver hint the GPU maker's RV740 will ship as the Radeon HD 4730 and Radeon HD 4750.
Fresh details emerging out of the inspection of the driver information files of ATI Catalyst version 9.1, as German website ATI Forum finds out, hints at the possibility of the RV740 being implemented in two SKUs: the Radeon HD 4730 and Radeon HD 4750. While in the driver file, the device string lists with "RV630", it can be seen throughout the file that several strings are assigned to the same RV630, and is merely a means to identifying a whole class or generation of graphics processors to the driver. Additionally, the string bears the device ID of the RV670, again, that's not relevant. The strings are what matter.
It's expected that ATI will debut the RV740 GPU at CeBIT in March.
