Today at CeBIT AMD showed off its first 45nm chips, which will bring them on a par with the miniaturization on the latest Intel chips later this year. Unfortunately, little is known regarding these new quad-core processors other that there will be both desktop-oriented versions, codenamed "Deneb," as well as server-grade "Shanghai" chips available.
The chips should enable AMD to erode some of the technological edge Intel has enjoyed over the past few years, though it isn't like AMD is close to be releasing these processors just yet. The company's first 45nm will not appear until the second half of 2008, while Intel is scheduled to start moving to a 32nm scale next year.
