An anonymous reader writes "Rumors said the release wouldn't be until late Q4 but an August ship date is now promised for AMD's quad-core chips. They're only releasing up to 2.0 GHz processors at first, with the top speed devices coming out later in the year. 'AMD's Barcelona puts four cores on a single slice of silicon, an approach AMD calls native quad-core, and the company has argued that Barcelona will outperform the Xeon 5300. The only problem: that comparison soon will become obsolete. Intel's second-generation quad-core server processors, Harpertown a server member of Intel's Penryn family, will arrive this year, too, with the promise of better performance, lower power consumption and lower manufacturing costs by virtue of a manufacturing process with 45-nanometer features. AMD is only just now moving to a 65-nanometer process.'"
