Intel expects 45-65nm crossover to be reached in 2008
After the planned launch of 45nm processors in the second half of 2007, Intel will likely reach the crossover between 45nm and 65nm nodes in CPU production in 2008, said Rob Willoner, technology analyst at Intel’s technology and manufacturing group. He confirmed the chip giant has already started transitioning to 45nm technology at its D1D fab in Oregon. The Oregon fab will be the company’s first to start volume production of 45nm processors, he added.
According to Willoner, Intel usually reaches a crossover in CPU production between two latest process nodes once every two years. He said that the company reached the crossover between 65nm and 90nm nodes earlier this year. Codenamed Penryn, Intel’s first 45nm dual-core design project has already entered a phase of debugging in silicon, when the company manufactures samples for internal use. Penryn will come out in server, desktop and mobile versions, featuring new power management modes and 48 new SIMD (Single Instruction Multiple Data) instructions, called SSE4, specific to multimedia and high-performance computing applications, according to Intel. Compared to the company’s current dual-core CPUs based on the Intel Core microarchitecture, it will also have higher core speeds and larger caches.
