I don't know if what this guy is saying will actually happen, but if it does...the future looks bright for AMD. I'm not very technical, so understanding how cpu's work and their integration with other parts of the computer is difficult for me to even comprehend. Never the less, here's the article and hope you guys can pitch in the discussion.
Is this LEGIT?
IDK, apparently they are going to ship with GDDR comparability and I think DDR4. Honestly DDR4 is quiet fast as it is. What I would be looking for is the ability to Cfire it with one of their entry level gaming cards.
One thing that might implicate that Kaveri won't support gddr or ddr4, is that the new A88X motherboards don't mention anything about it. But maybe when the actual APU hits the market, they'll come out with new boards.
Never the less, the Carizzo APUs scheduled for 2014 (or is it 2015?) will most definitely have DDR4 and probably GDDR compatibility.
