Intel says the first 45nm processors, codenamed Penryn, will be available in the second half of 2007. The company also said the crossover between 45nm and 65nm nodes in CPU production will be reached in 2008.
The D1D fab in Oregon will be the first fab to make 45nm processors.
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.
