ATI is planning to launch RV730XT and it looks that the new card will end up branded Radeon 4670. The new chip will work at 750MHz, while with the 4650 the chip should be clocked at 600MHz.

The memory with Radeon 4650 will work at 1000MHz, while the 4650 will work at 900 MHz. ATI is preparing to launch these cards in mid-to-late September.

Radeon 4670 will launch and be available by mid-September, while 4650 should be available by the end of the month.

ATI is positioning this card against Geforce 9500GT, and from what we've seen, it clearly wins.
