Possibly 28NM 6800 series by ATI. They don't give much info but I did not know where else to put it. I also don't know much about the ins and outs of specs on these types of things. But here you go for what it is worth. Hopefully we are looking at the new 6870 from ATI and GF.
It would be nice if is a head of schedule.
I also don't think I double posted this time. HEHEHE
