Ultimately, Intel's future Pentium 4 line can be broken into two families: Presler chips, which are due in the first part of 2006 and Conroe desktop processors, which are due in the second half of 2006. Both dual-core processors will be based around an 800MHz front-side bus, which helps speed the chip's complex computations.
Presler, the successor to Smithfield, features two physically separate Cedar Mill processor cores in a single package. The chipsets accompanying Presler will feature EM64T (64-bit translation capabilities); virtualisation that juggles multiple tasks by dividing them into separate regions for personal, work and administrative uses; enhanced speed step to help power up and down the processor cycles; LaGrande security system; and execute/disable, or XD technologies, which were designed to work with operating systems like Microsoft Vista to head off virus and Trojan threats.
Intel motherboards based on Presler and its corresponding 945P and 945G chipsets include code names such as Radio Springs, Palm Canyon and Marblewood.
