Pentium 4 overhaul

Quote

Code-named Nehalem, the chip will embody a new architecture that will substantially differ from the current Pentium 4, according to sources. Concepts in the current chip line will be found in Nehalem, but it will contain new, and largely unknown, features such as improved power management that will mark it as a distinct evolutionary step, similar to the changeover from the Pentium II to the Pentium III.

In the meantime, Intel is also working on updates to the Pentium 4. In the second half of 2003, the company will release "Prescott," a Pentium 4 variant that will feature a new security system and "strained silicon," a chipmaking method that speeds up transistors.
