Intel is working on a 3GHz Core 2 Duo processor that runs on a 1333MHz FSB:
Despite of the trend towards multi-core microprocessors, Intel Corp. will continue to boost performance of its dual-core central processing units (CPUs) by increasing their clock-speeds and processor system bus frequencies. According to slides presumably from Intel’s roadmap published by a web-site, desktop Core 2 Duo chips with 1333MHz bus will emerge in the third quarter of 2007.
The slides published by Matbe.com web-site claim that Intel will release Intel Core 2 Duo processors with E6850, E6750 and E6650 with 3.0GHz, 2.66GHz and 2.33GHz clock-speeds respectively and 1333MHz processor system bus in Q3 2007, when appropriate code-named Bearlake-series chipsets become available. The new microprocessors will also support technology called TXT, according to the slides which do not elaborate on the nature of the capability.
