This week, Intel released a new generation of Xeon server microprocessors based on the Core architecture. The Xeon 5100 chips offer about twice the performance of the chips they're replacing while consuming 40 percent less power. Also, they give Intel a technical edge over AMD that's been lacking for about three years. Later this year, Intel will also ship desktop and notebook chips based on the new design. These chips, dubbed Core 2 Duo, will feature two processor cores and will replace all of Intel's current-generation mainstream processors
