'''Hyper-Threading Technology''' is a technical method developed by [[Intel]] which increases the flow of data to a single [[Central processing unit|processor]] core. This method enables more efficient use of a processor, since it is less likely to stall (stop and wait) when data is needed after a state change or for other reasons. Some software (such as the Windows task manager) sees a hyper-threading device as two cores.  However, this is only a slightly better utilization of a single core.  While a statistically significant improvement, Hyper-Threading does not run with nearly as much efficiency as a pair of cores.  Nonetheless, hyper-threading technology can be applied to multi-core systems, enabling slightly better performance for all cores.<ref>https://www.intel.com/content/www/us/en/architecture-and-technology/hyper-threading/hyper-threading-technology.html</ref><ref>https://www.makeuseof.com/tag/hyperthreading-technology-explained/</ref><ref>https://lifehacker.com/how-hyper-threading-really-works-and-when-its-actuall-1394216262</ref>

'''Hyper-Threading Technology''' is a technical method developed by [[Intel]] which increases the flow of data to a single [[Central processing unit|processor]] core. It was first released in 2002 on Xeon and Pentium 4 processors.
