Does anyone really know what AMD is doing next?

230HP-Bulldozer-MD23There is a ton of contradictory information on the net today about just exactly what AMD and Globalfoundries are going to do with the next process. As we already know AMD’s next gen CPU Bulldozer will be a 32nm 8-core monster that has the potential to turn things around for AMD (at least on paper) that is if they can correct some of the past issues with memory performance.  What happens from there we are not so certain about, nor is anyone else for that matter. This is despite the fact that multiple journalists ended up at a press event hosted by Globalfoundries.

So far the rumors run something like this; AMD and Globalfoundries are moving away from SOI (Silicon on Insulator). SOI has been the basis for AMD CPUs for some time and to see them move away from this is a little shocking. Oh, wait; that rumor was contradicted by Globalfoundries who now say they will be sticking with SOI moving forward. Next we hear that AMD won’t move to the next node (28nm) until 2013. This is actually somewhat believable as AMD tends to try and get the most money out of any process move. After all they have been on 45nm for a number of years! To think they won’t move to the next process node until 2013 is not unreasonable (although I really think 22nm is much more likely).

To add to this are the usual suspects commenting back and forth about what they think of each article or the writer in general. It makes trying to find out real information a tad tedious.  To be honest about the only thing we know for certain is that AMD will launch Bulldozer sometime between the middle of September and the end of the Year. It will have 8 physical cores (in four CPU clusters) improved core to core communication and a few other tricks up its sleeve. We do not know much about the memory controller, but it appears from looking at the design to be a slightly modified revision of the one in the Phenom II. If this is the case and the optimizations are not spot on we could see this hinder what is certainly a bold CPU design from AMD. I guess we will all find out what is going on around the middle of September. We hope to be on the very short list of sites to review this new CPU for you, but again time will tell on that.
