MBCook writes "AMD Hammer line is definatly moving forward. The Inquirer has a supposidly leaked memo from MS saying that they have working x86-64 silicon that runs both 32 and 64-bit Win XP. Van's Hardware is reporting that MS is backing x86-64 over Intel's IA-64, and that MS has apparently convinced Intel to move to x86-64! There is an article over at Ace's Hardware from CeBIT that includes some coverage of AMD's Hammer line (including its NUMA). Last but not least is News.com's report that MS is preparing Windows to support NUMA." And it looks like the line will be named Opteron.
