As next year comes to a close, Intel President Paul Otellini said, more than half of the "high-performance" chips that Intel ships will have dual cores. That means the chips will enter at the high-end, coming in more expensive PCs at first. Otellini spoke at the company's spring analyst meeting in New York on Thursday. Intel believes the dual-core approach will let it offer greater performance for desktops and notebooks while circumventing power-consumption problems. Dual-core chips offer more performance than single-cores by adding more parallelism, or the ability to do multiple jobs simultaneously. A dual-core processor could, for example, render a video on one core while running a PC's operating system and other applications on its other core, Otellini said. Read more: CNet News.
