I've been seeing a lot of talk about pixel throughput being dictated by gcn cores and not ROP's in the future. Where does this leave ROP's? The PS4 apparently has already gone overkill with its 32 ROP's, what are developers going to do with that extra room they have with ROP's? Disclaimer: I know nothing about what I'm talking about, the line of logic I have used above is based on total ignorance. So it probably doesn't even work. Edit: If I'm a lost cause here, and I'm talking completely out of my back end, a book recommendation on how GPU's work will be more than helpful.
