Globalfoundries has started its production ramp on 28nm and anticipates a much smoother ride on 28nm than it had on 32nm.

Despite an amended wafer supply agreement that gives AMD the right to use other foundries to make its 28nm accelerated processing units (APUs), Globalfoundries expects AMD to increase its business with the firm in 2012.

Rumors surfaced online today that claim TSMC has pulled the plug on their 28nm manufacturing lines and that the company started to test and tune the machines to improve yields.

Advanced Micro Devices has said it agreed to a negotiated wafer price mechanism with Globalfoundries for 2012 and also agreed to transfer its remaining ownership interest in that company to the firm itself.

Clearly, this action tends to cast doubt on the validity of all future data published by WSTS. That sort of uncertainty has a huge ripple effect. It will impact chip companies doing planning and forecasting, market research analysts who depend on WSTS numbers - interpret them and predict market trends, and broad-spectrum media outlets.

Advanced Micro Devices has disclosed at an analyst event that it had begun manufacturing of its chips at IBM's facilities. The partnership is believed to ensure AMD's ability to supply its next-generation A-series Fusion chips code-named "Trinity" to PC makers and be in position to compete against Intel's Core i-series future products.
