Today Intel finally released the Pentium 4 3.06GHz !
Here's a quick snip from X-bit Labs about the Hyper-Threading :
Having launched a new Pentium 4 3.06GHz processor today, Intel not only raised the performance bar for its CPUs thus turning into a performance leader in the race with AMD, but also introduced an extremely interesting Hyper-Threading technology to the world.
In fact, it is still impossible to evaluate the cons and pros of Hyper-Threading to the full extent today. On the one hand, this technology will give green light to virtual dual-processor systems entering the market of high-performance home and office systems. The advantages of the technology are evident: the performance as well as response time when working with the existing applications get improved in most cases. However, there is always other side to the picture. Many contemporary tasks optimized for actual and not for virtual multi-processor configurations can be slowed down notably by Hyper-Threading technology. Besides, there are also quite many tasks, such as games, for instance, which performance does not depend on Hyper-Threading at all. Anyway, so far the advantages are dominating, so that the use of Hyper-Threading appears justified in most cases, if the system is not intended for any specific needs.
