There are many sites that are reporting on the R680, RV620 and RV635 today. What I understand is this sentence from DailyTech's story:
"Representatives from AMD would not confirm that the R680 is essentially two RV670 GPU cores on the same board, though the company did confirm that each core has the same specifications of an RV670 processor."
I have underlined the important parts of that sentence. So the R680 is not essentially two RV670 cores yet each core is a RV670. That sounds like there is more than one RV670 core on there, and there are not two of them. That makes me think there are more than two RV670 cores on the R680. What do you guys think about this sentence?
Guru3D's article tells us that the RV620 and RV635 are "nearly identical" to their RV610 and RV630 brothers. The XT Review article (try to read around the stoopid ads) actually give us release dates for these new parts. January 28th for the R680 and January 23rd for the RV620 and RV635.
