Advanced Micro Devices' much-publicised production woes have forced the processor vendor to lower by some 20 per cent its forecast for this year's shipments of the flagship K6 processors.
The chip vendor now expects to be able to ship only 12 million K6 processors this year, as compared to earlier forecasts of 15 million units, says Mark Lunsford, AMD's Tokyo-based director of marketing for the Asia-Pacific region and Japan.
Although rival Intel continues to gain market share for its high-end Pentium II chips, AMD still expects around 40 per cent of total worldwide PC shipments this year to feature so-called Socket 7 processors, Lunsford said.
The K6 and other Pentium-class processors from vendors such as Cyrix all fit into motherboards featuring the older Socket 7 architecture, while Intel's Pentium II chips can only be mounted on boards featuring the proprietary Slot 1 design.
The long-awaited K6-3D will be manufactured using 0.25 micron process technology, as opposed to the 0.35 micron design rules of past K6 iterations.
And there's the rub: AMD's planned move to the more advanced 0.25 micron production technology has met with serious delays, officials admitted.
By the end of the second quarter, however, AMD will have re-tooled its wafer fabrication plant and all future K6 parts will be manufactured on the 0.25 micron technology, Lunsford said.
