That sound you hear off in the distance is champagne corks popping over at AMD's headquarters. Earlier this morning, the chipmaker announced that it has started revenue shipments of the first processors based on its next-gen Bulldozer microarchitecture.
Enthusiasts eager for an upgrade might not want to celebrate quite yet, though. First, these first shipments are of 16-core Interlagos processors, which are firmly targeted at servers. AMD says in its announcement that "many of the initial shipments have been earmarked for large custom supercomputer installations that are now underway." On top of that, the company goes on to note that Interlagos CPUs will only become available in the fourth quarter of this year.
In other words, if server offerings aren't due out 'til Q4, and desktop-bound Bulldozer chips haven't shipped yet, then you can probably forget about the desktop parts coming out in September as the rumor mill had hinted.
This wouldn't be the first time has AMD premiered a new microarchitecture in the server world before making it available on the desktop. Back in 2003, server makers were treated to the first Opteron chips in April, but desktop Athlon 64 CPUs didn't come out until September. The gap between the two versions should be shorter this time, though.
