Hyper Threading Tech of Intel’s Processor

How does the hyper threading technology of intel's Processor works ? How much performance boost I get ?

             Hyper-threading of Intel’s processors functions in the way that some sections of the processor is duplicated, specifically the architectural state. It is important to note that in this process, the main executions resources are not duplicated. This duplication enables the operating system in scheduling of two threads, which also means processing tasks simultaneously. In simpler terms, it just utilizes that those resources that are supposed to be idle, and maximizing the performance level of your system.

Hyper Threading Tech of Intel’s Processor

Hyper-Threading or just “HT” is a kind of technology used by several Intel microprocessors that lets a single processor act like two individual processors to the applications and operating systems that use it. It is one of the features of Intel’s “IA-32” processor architecture. With Hyper-Threading, the “core” processor of a microprocessor can execute two simultaneous streams or threads of instructions instead of one sent by the operating system.

With two streams or threads of execution units to work on, this allows more work to be done by the processor for every clock cycle. On the operating system like Microsoft Windows, a Hyper-Threading processor looks like two separate processors.

Since most of today’s operating systems like Linux and Microsoft Windows have the capacity to split their work load among multiple processors, also called SMP or Symmetric MultiProcessing, the operating system just acts as if the Hyper-Threading processor is a pool of two processors.
