AMD still hasn’t said when exactly it plans to launch its highly anticipated FX-series Bulldozer processors, though a promotional cartoon advertising the company’s Scorpius platform and FX chips suggests it could happen on September 19th. That seems as likely as any other day in September, given what motherboard makers have to say on the matter.

News and rumor site DigiTimes has been talking to its sources behind the scenes in the motherboard industry, and according to those sources, AMD is busy mass producing Bulldozer parts for a launch next month at the earliest, meaning it’s not set in stone. Either way, mass shipments are scheduled for October, the sources say, so whether or not Bulldozer does end up launching in September, it might be another month before there’s sufficient stock.

Those same sources also claim to have the inside scoop on AMD’s staggered release schedule, which includes an initial launch of the chip maker’s upcoming FX-4100 (quad-core, 95W), FX 6100 (six-core, 95W), FX-8100 (eight-core, 95W), and FX-8150 (eight-core, 125W).
