Two days ago, Intel was presenting its roadmaps for future processors, as well as the new technologies developed to boost performance while reducing power consumption, HyperThreading remains in the dark with no information regarding the future of this technology. As a reminder, HyperThreading (HT) is a trick introduce to mimic a second core on a single core processor. If you are using a HT-enable P4, performances with some applications can be boosted between 10-20%.
If Intel does not mention HyperThreading, probably because the decision ahs already been taken to drop it, it is rather a quite normal evolution. Indeed, HT was introduced as a trick to improve performance of P4 processor at the time Intel was facing issues with power consumption and increasing clockspeed of his CPU. It was msotly a way to compensate the 31 stages pipeline of the P4.
What is making Intel extatic today is Virtualization, and not HyperThreading anymore.
