Advanced Micro Devices (AMD) will ship four-core processors for servers, workstations and high-end desktops by mid-2007, company Chief Technology Officer Phil Hester said Thursday.The company will also launch a new dual-core design for mainstream desktops around that time. All four new processors will use AMD\u2019s new 65-nanometer process chip architecture, he told a room full of analysts at the company\u2019s annual Technology Day in Sunnyvale, Calif.AMD has led Intel in the move to dual-core processors, but Intel is set to raise the ante by shipping four-core chips in mid-2007. AMD\u2019s announcement will allow it to match that bid.In addition to building chips with more processing cores and smaller components, AMD wants to build more efficient products. On Thursday, the company revealed plans to build a highly efficient dual-core notebook processor, set for release in the second half of 2007.Power efficiency is a major theme in the company\u2019s constant battle with Intel. AMD often claims superior power efficiency, expressed as performance per watt. The new family of chips will continue that theme by implementing a system that changes the frequency in each core to match its workload, Hester said.Compared to today\u2019s Opteron processor-powered servers, that approach will boost efficiency by 60 percent in 2007 and 150 percent in 2008.Likewise, AMD will use a similar approach to control power drain in the next-generation mobile processor. That dual-core chip will switch the power on or off in its cores, using only enough power to match the demands of its workload.At the analyst event, AMD also disclosed plans to open up its chip design to third-party developers, an effort the company has code-named "Torrenza." AMD hopes the effort will help it gain more partners among PC vendors in its effort to chisel market share away from giant Intel.Under the Torrenza plan, AMD will share the company\u2019s chip design with third-party developers, allowing them to develop application-specific co-processors to work alongside AMD chips in a multisocket system. The company also shared new market strategies to cut costs for enterprise IT managers by delivering a security bundle and by promoting thin-client computing.AMD will offer software tools to its OEM partners, allowing them to reduce IT costs for commercial client and server platforms by linking three features: security, virtualization and manageability.These open business models could spell success for AMD in its efforts to enlist more partners, analysts said."If Torrenza will play up to their Direct Connect architecture, that means they will be pushing that architecture in general. That is an excellent opportunity to leverage openness and cultivate the entire ecosystem," said Kelly Quinn, an analyst with IDC.AMD also shed a little light on its road map for shrinking the wires and gates on its microprocessors.AMD is already making processors using a 90-nanometer process, but by the end of the year it expects to be producing 65-nanometer process chips. It will move to a 45-nanometer process by 2008 and shrink to 32 nanometers by 2010. AMD is even working on 22-nanometer technology today, in a joint research arrangement with IBM.-Ben Ames, IDG News ServiceFor related news coverage, read AMD Woos Gamers With 4X4 Platform and AMD\u2019s Home-Entertainment Platform to Go Live in June.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
