Core architecture--previously know only as Intel's next-generation microarchitecture--will be used in the second half of the year in its Woodcrest processor for servers, Merom processor for mobile computers, and Conroe processor for desktop PCs.Intel demonstrated its Woodcrest server platform in a simulated test against an existing Sun Microsystems server using Opteron processors from Advanced Micro Devices Inc. That test indicated that the new Intel processor had a 35% performance improvement and 1.4X improvement in performance per watt over the Opteron processors. With Conroe, Gelsinger said the new processor will provide a 40% boost in performance compared to existing desktop Pentium processors, while providing an "almost magical" 40% reduction in power.
