This new processor is fabricated with the latest .13µ (micron) technology, 512KB-L2 cache, and the ability to support frequencies ranging from 1.8 GHz to greater than 2.6 GHz. This processor also includes support for multi-threaded execution, known as Hyper-Threading technology. The purpose of this paper is to provide an overview of HyperThreading technology, to analyze and study the performance impacts of the system with Hyper-Threading technology, enabled as well as disabled, and to provide the technical information and benefits of this feature.
