Too Early To Tell With Hyperthreading

I found this article which I thought interesting.It's only partial,the rest can be read at PC World.

The latest Pentium 4 processor not only passes another megahertz milestone by running at 3.06 GHz, it also introduces Intel's new hyperthreading technology to the desktop.

Hyperthreading enables one processor to act like two. As a result, it can simultaneously tackle multiple applications (or a single application that has multiple threads), put idle CPU cycles to use, and boost system performance by up to 25 percent--all without requiring specially written applications, according to Intel.

Sounds good, doesn't it? Exclusive PC World tests on three of the first systems to use the new processor, however, show that hyperthreading's benefits largely are application- or even task-specific. For example, on the office applications that most people use--such as Microsoft's Word and Excel--hyperthreading had a neutral or slightly negative impact. And on tests specifically designed to expose the benefits of hyperthreading, many improvements were too slight to be detectable by the average user, except with select filters in Adobe Photoshop, with various video and photo programs such as Adobe Premiere and Roxio VideoWave, and on certain multitasking tests.

Furthermore, a comparison system equipped with AMD's Athlon XP 2800+, which runs at 2.25 GHz, more than held its own against these 3-GHz powerhouses that were running 800 MHz faster. Nevertheless, hyperthreading remains a very new technology, and Intel anticipates further performance improvements as applications are modified to take better advantage of it.

I did a search here to see if someone had posted this subject.
