It was first introduced with Intel’s Xeon chip, and then it made an appearance to the consumer-based SoCs with the Pentium 4. It is present in Intel’s Itanium, Atom as well as Core ‘i ‘ series of processors.
What is HyperThreading in computers?
It is like making the waiting time or latency for the CPU to switch from one task to another being negligible. It allows each core to process tasks continuously without any wait time being involved. With Hyperthreading, Intel aims to bring down the execution time of a particular task for a single core. This means that a single core of a processor will be executing multiple tasks one after the other without any latency. Eventually, this will bring down the time taken for a task to be executed fully. It directly takes advantage of the superscalar architecture in which multiple instructions operate on separate data are queued for processing by a single core. But for this, the operating system must be compatible too. This means that the operating system must support SMT or simultaneous multithreading. Also, according to Intel, if your operating system does not support this functionality, you should just disable hyperthreading. Some of the advantages of Hyperthreading are- Summing up, if you have a machine that is used to pack some box, the packing machine has to wait after packing one box until it gets another box from the same conveyer belt. But if we implement another conveyer belt that serves the machine until the first one fetches another box, it would boost the speed to pack the box. This is what Hyperthreading enables with your single-core CPU.
