Intel has produced its first working samples of chips based on 45 nanometre technology and will have a million ready for market in the third quarter of the year. 

According to Techworld, the 45nm process is codenamed Penryn and covers both the new geometry and updated Core 2 technology. Chips using Penryn will go into production in the second half of 2007 and Penryn will be the basis for Intel's processors of the future, making up the bulk of Intel chips in 2008
The product line covers Intel's complete range of desktop, notebook and server processors and is said to deliver better power savings and a fourth generation of streaming SIMD extensions (SSE), which fold additional digital signal processing instructions into the CPU.
Initially, there will be both dual and quad-core versions, codenamed Wolfdale and Yorkfield respectively, with the possibility of an eight-core version in the future.
