This was contrast to Intel which had it much further out. As I recall the speculated reason was the silicon process Intel was using allowed them to put off that complexity longer. > > http://www.eetimes.com/showArticle.jhtml;jsessionid=WE1VYQTG2ZE5YQSNDLOSKHSCJUNN2JVN?articleID=196604387 > > http://www.eetimes.com/showArticle.jhtml;jsessionid=WE1VYQTG2ZE5YQSNDLOSKHSCJUNN2JVN?articleID=199700463 > > Today TI has chips with multiple variable voltage planes so seeing the same out of a company like AMD is not so hard to believe. I'm the last person to know details of unreleased AMD features (working for Intel and all that) but all the things I've read so far suggest only the memory controller will have it's own voltage plane, but that the two cores still share the same plane. Maybe there'll be a surprise when AMD launches the actual hw ;) -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
