Now that the 9.1 Catalyst drivers have been released, german website ATI Forum has dug into the driver information to see what they can pluck from it in the way of future plans; what they discovered is that the world's first 40nm GPU (codenamed RV740) will come in the form of not one, but two SKUs, now known as the Radeon HD 4730 and HD 4750.
Although the device strings throughout the information files show as "RV630", this is just redundant code and is not relevant, unlike the rest of the strings which give the clear picture. The few supposed specs we have seen thrown around are a 128-bit wide GDDR5 memory interface (a mainstream first with GDDR5 memory) and 640 stream processors.
It's likely RV740 will go into full swing come CeBIT (March) as refreshments to ATI's entry level lineup.
