According to Legit Reviews, who is out wining and dining with AMD at the AMD Evergreen Vision launch event, the chip maker plans to launch a pair of new videocards on September 22nd, the ATI Radeon HD 5870 and HD 5850.

AMD hasn't yet said a whole lot about its upcoming graphic cards, but news and rumor side Fudzilla feels pretty confident the RV870-based HD 5870 will come clocked at 825MHz and boast 1,600 shaders, which is twice as many as RV770. It will also pack as many as 2.1 billion transistors, which is more than twice as many as RV770.

Other purported  specs include an unspecified amount of GDDR5 memory clocked at 1.3GHz and 150GB/s of bandwidth.

The less powerful HD 5850 is expected to come clocked at 725MHz and ship with 1,440 shaders, while the same GDDR5 memory will race along at 1GHz. Both cards will come with 32 ROPs, Fudzilla says.
