Intel's new Pentium 4 6xx series and Pentium 4 Extreme Edition 3.73GHz

Intel today officially launched five new 64-bit processors including the Pentium 4 600 series and also the Pentium 4 Extreme Edition 3.73GHz.

All five support Intel's EM64T, the 64-bit technologyu which will become available for all newly introduced Intel desktop processors - including the Intel Celeron D which will be launched later this year.

The Intel Pentium 4 Processor 6xx sequence processors help enable new power-saving benefits to the desktop with Enhanced Intel SpeedStep Technology (EIST). Similar to the technology used in Intel Centrino Mobile Technology, EIST can enable power-saving by reducing overall average processor power consumption.
