If you thing nVIDIA has nothing to worry about, think again: ATI's target is to equal or outdo the performance of R580 with fewer Shader units, but staying around the same clock.More details over here.
The line-up consists of three models: two Hellfires and a Gemini. Hellfire-1 will be probably marked as the X1950XT, although nothing is set in stone. The GPU will be clocked somewhere around 600 to 650MHz for the GPU, while the 512MB of GDDR-3 memory is scheduled to run at 700 or 750MHz DDR (1400-1500MHz).
Since the RV570 chip has nice 512-bit internal (256-bit external) memory controller, you can expect bandwidth figures of 48 GB/s.
ATI Radeon X1950XT delayed to September
