ATI Radeon HD 4000 Series discussion

As we have already seen the Rv770 die size and we know that the die size is only 50% larger, the 50% more SP theory (480 SPs) sounds more practical.

Those are my 0.02.

You've not been posting much lately, so I understand.

Here, you can have them back....


SP's alone to not make a gpu. ROPs, TMUs, cache, memory interface, and any other logic also account for die space. Since we are talking ati cards here, lets add in UVD/HDMI functionality, etc...doubling SP's @ 50% die increase seems more than reasonable to me.

I mean really, how else is R770 different from R670?
