Dow Jones reports that AMD is cutting its revenue and gross margin guidance citing manufacturing problems at its foundry, Globalfoundries. The recent APUs “LIano” are also in shortage due to Globalfoundries not able to meet the high demand of such APUs.

The news sent AMD shares down 8.6% to $5.62 in after-hours trading. The Sunnyvale, Calif., company designs semiconductors that serve as calculating engines in computers, servers and game consoles.

On the other hand, there is also no confirmation of it’s highly anticipated 8 Core Bulldozer processor.
