Chipmaker falls on production glitches

Advanced Micro Devices Inc. fell after the second-largest maker of processors for personal computers cut its forecasts for third-quarter sales and profitability, citing manufacturing glitches. Sales in the period ending Oct. 1 will rise 4 percent to 6 percent from the previous quarter, the Sunnyvale, Calif.-based company said. That compares with an earlier prediction of about 10 percent. Globalfoundries Inc., a spinoff of AMD’s manufacturing operations that now supplies the company with chips, is having difficulties with production at its plant in Dresden, Germany, causing a shortfall of AMD’s latest processors, the company said. The glitches are a setback as AMD rolls out its new Llano chip for laptops, which has drawn steady demand.
