Hyper-threading is a technology from Intel that creates virtual cores or threads on a CPU. The operating system treats these threads as if they were physical cores and can assign tasks to them in parallel. Hyper-threading can improve performance in some applications that require heavy processing or multitasking.
Hyper-threading works by allowing each core in your CPU to do two actions at the same time. In turn, you get better processor performance since it’s improving the CPU’s efficiency. This way you can use more demanding apps or games at the same time. For example, if you have a CPU with 4 cores and hyper-threading enabled, then your operating system will see 8 logical cores that can run 8 tasks simultaneously. However, this does not mean that hyper-threading doubles the performance of your CPU, as there are still limitations on the physical resources of each core.
