Sources told The Register late today that Advanced Micro Devices (AMD) was considering suspending its deal with IBM Microelectronics to fab out its K6 chips. Earlier today, as reported here, AMD disclosed figures of the wafers made by its fabs, suggesting that it is close to achieving critical mass on its processors off its own bat. Last week, NatSemi said it would be able to produce 75 per cent of its production without the aid of IBM Microelectronics by the end of the year. No-one from IBM was available for comment at press time. ®
