Hyper-Threading Technology (HT Technology) is ground breaking technology that allows processors to work more efficiently. This technology enables the processor to execute two series, or threads, of instructions at the same time, thereby improving performance and system responsiveness.
Many of today's operating systems and applications are multi-threaded for use on multi-processor systems, providing higher performance. In these systems, separate processors and supporting hardware and firmware schedule and execute code in parallel.
With HT Technology, a single processor can simultaneously process two threads of code, improving the performance of multi-threaded code running on a single processor.
HT Technology is based on the inherent performance enhancements of the Intel NetBurst® microarchitecture
