An update to my post earlier today on Shanghai, AMD's 45nm processor due around the end of this year. The site Fudzilla says internal data shows the quad-core desktop version, code-named Deneb, can reach speeds as high as 3.2GHz.
The fastest 65nm Phenom X4 has topped out at 2.5GHz, though AMD had plans to reach higher clock speeds. So a 3.0GHz or faster quad-core chip would be a big boost for AMD, and it could make it competitive with Intel's current Penryn chips, as well as Nehalem, a new design that will ship around the same time.
