AMD Phenom II at 4GHz
AMD's mainstream Phenom II processors should rekindle the competition with Intel for clock speed, according to a collection of reports of an AMD demonstration session. Based on the recently unveiled Shanghai architecture being used for new Opterons, the quad-core desktop chips should make a modest leap to 3GHz in official clock speeds but will have room for overclocking previously only available with Intel's Core 2 chips. An example tested by AMD is capable of running reliably at 4GHz with fan-based cooling and shows the company could upgrade the clock speed to match or beat Intel if necessary.
AMD 45nm Demo
AMD today stepped closer towards equality with Intel today by revealing the first working examples of its own 45 nanometer processors. Co-developed with IBM, the chips combine AMD's own existing quad-core technology with the smaller, more efficient chip design to improve the amount of performance without increasing power and heat as a result. The company is still hesitant to reveal full details but explains that there will be both desktop-oriented processors, codenamed "Deneb," as well as server-grade "Shanghai" chips available; these are expected to translate to both single- and dual-socket upgrades to the Phenom desktop line as well as more efficient Opteron processors later in the year.
