I am not believing all this just yet, but I would love to ATI pull an R300 out of the bag with the GTX going the way of the 5900

I do doubt the 800 SP rumours because 800SPs increases the die size dramatically, and since the process is the same as the 3870, we know that doubling the TMUs and more than doubling the SPs would be next to impossible without having a gigantic diagonal 90nm R600 size die:



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.
