Pentium 4 - Wikipedia, the free encyclopedia: "The Pentium M has now reportedly become the internal reference layout for Intel’s design teams, and P4 development has been essentially abandoned. To this extent the little-funded Israeli design team that produced the Pentium M core, has now taken over the much larger desktop development project.

Why the Prescott ended up in such a disaster can be attributed to internal politics at Intel. The marketing department wanted ever higher clock speeds, to differentiate their products from AMD. Processor design was dictated by marketing needs, rather than architectural requirements. Careers were then built on the concept of higher clock speeds, and the termination of the P4 project when it finally came, had consequences for many members of the management team at the well-funded desktop division."
