IBM (Quote, Chart) and AMD (Quote, Chart) have devised a new silicon transistor technology they claim will boost the speeds of single- and dual-core chips. (excerpts) The process, known as "Dual Stress Liner," uses IBM and AMD's jointly developed strained silicon technology and could increase transistor speed as much as 24 percent without using any additional power, the two companies said. IBM and AMD said the technique works without the help of additional new processes, which may be welcome news for chipmakers struggling to boost chip speeds without overheating computer systems. "Innovation has surpassed scaling as the primary driver of...
