In the second half of 2007 we can expect Intel's first 45nm processors which will also feature 50 new instructions (SSE4) to boost multimedia and web applications performance.
During Intel Developer Forum Fall 2006 the world’s largest chipmaker revealed plans for more than 50 new SSE4 instructions, extending the Intel 64 instruction set architecture [formerly called IA32e – X-bit labs] “to better take advantage of Intel’s next-generation 45nm silicon manufacturing process and expand the performance and capabilities of Intel Architecture.”
Intel said that products, which code-names are presumably Wolfdale, Penryn, Yorkfield/Bloomfield as well as server chips, made using 45nm process technology will first appear in 2007 and will benefit a variety of applications, including those involving graphics, video encoding and processing, 3D imaging, gaming, web servers and application servers. The new chips will be based on the Core 2 micro-architecture.
Intel was originally expected to launch dual-core Wolfdale (for desktops) and dual-core Penryn (for laptops) processors made using 45nm process technology in 2008, according to earlier information.
