Sunnyvale, California chipmaker Advanced Micro Devices Inc says it expects to post a small operating loss for its third quarter ending September 28. The company blames its current migration from 0.35 micron technology to 0.25 micron technology for the lower-than-expected number of K6 processors shipped during the quarter. Slightly more than one million are expected to be produced this quarter, but AMD says that isn’t enough to offset the costs of ramping the K6. Two million units is the current target for the fourth quarter.
