Pentium D

Pentium D is a series of microprocessors introduced by Intel during the Spring 2005 Intel Developer Forum. It consists of 2 Pentium 4 Prescott processors on a single die. The inital release the Pentium D (codenamed Smithfield) is expected for Q2 2005 with clock speeds of 2.8, 3.0 and 3.2 GHz. The Pentium D will not support Hyperthreading, at least initally, although similar Pentium XE counterparts will. The Pentium D will also implement true x86 virtualization, and numerous Virtual Machines, such as VMWare, will no longer have the mild overhead incurred by trapping protected mode calls.
