Pentium D/Extreme Edition
The twin-core CPU is capable of running multi-threaded applications typical in transcoding of audio and video, compressing, photo and video editing and rendering, and ray-tracing. Single-threaded applications alone, including most older games, do not benefit from the second core of dual-core CPU compared to equally clocked single-core CPU. Nevertheless, the dual-core CPU is useful to run both the client and server processes of a game without noticeable lag in either thread, as each instance could be running on a different core. Furthermore, multi-threaded games benefit from the Twin-core CPUs.
As of 2008 many business applications are not optimized for multiple cores. They run at similar speed when not multitasking on the Pentium D or older Pentium 4 branded CPUs at the same clock speed. However, in multitasking environments such as BSD, Linux, Microsoft Windows operating systems, other processes are often running at the same time; if they require significant CPU time, each core of the Pentium D branded processor can handle different programs, improving overall processing speed over its single-core Pentium 4 counterpart.

Famous quotes containing the words extreme and/or edition:
“We cannot permit the extreme in the environmental movement to shut down the United States. We cannot shut down the lives of many Americans by going to the extreme on the environment.”
—George Bush (b. 1924)
“Books have their destinies like men. And their fates, as made by generations of readers, are very different from the destinies foreseen for them by their authors. Gulliver’s Travels, with a minimum of expurgation, has become a children’s book; a new illustrated edition is produced every Christmas. That’s what comes of saying profound things about humanity in terms of a fairy story.”
—Aldous Huxley (1894–1963)
