Date added: 05/05/2011 PCMAG - 3D Transistors? We Don't Need 'Em, AMD's Foundry Says

Advanced Micro Devices and its manufacturing partner, Globalfoundries, said on Wednesday that the companies don't feel they need to adopt next-generation technologies until some time in the future.

Intel announced that it would employ a 3D transistor at the 22-nm generation with its "Ivy Bridge" microprocessors. Intel will introduce its 3D transistor design, called Tri-Gate, as it transitions to its next-generation, 22-nanometer silicon manufacturing process at the end of this year, through 2012, and beyond.

The Tri-Gate transistors, a fundamental revision of Intel's logical building block, will be used in both its desktop, mobile, and server processors, as well as the Atom embedded processor.

"I think it's an evolution of the manufacturing process but a little bit more significant than we've seen in the past," said Dean McCarron, an analyst with Mercury Research. McCarron called the new transistor model "essentially an evolutionary argument," and one that Intel picked after evaluating other approaches.
