The Santa Clara, Calif.-based chip giant will adopt a common processor core, code-named Merom, for its notebook and desktop lines of chips in 2007, according to sources, a shift calculated to bring greater energy efficiency to desktops and one that underscores that Intel is taking noticeable steps to move away from getting more performance through megahertz.
Merom will derive from the Pentium M line of notebook chips, which run at slower speeds than the Pentium 4 line of desktop chips but consume far less power. The Pentium M and Pentium 4 are built around similar--but distinctly different--cores, and each has features the other
