The 448SP part and the 512SP are going to have different clocks. The 448SP should come in, unless they have changed things, 450-475 for the core and around 1250-1300 for the domiain while having just 40ROPs. The 512SP part is 48ROPs and should come in at 600-625 core and 1450-1500 for domain clocks.
