16 ROP units only, but is more than equal match to G80.
Since the company believes this is the best way to keep all of the shading units well-fed, the target is to have 16 pixels out in every clock, regardless of how complex the pixel might be. But, don?t think for a second that R600 is weaker than G80 on the account of ROP units alone.
R600 isn't running on final clocks yet, but the company is gunning for 700 to 800MHz clock for the GPU,Twenty-four ROPs at 575MHz equals 13.8 billion pixels per clock, while 16 ROPs at 750MHz will end up at 12.0 billion pixels. At the same time, expect ATI to far better in more complex Shader-intensive applications.
