Hyper-Threading is a technology developed by Intel that allows a single physical processor core to act like two separate logical cores. This means that each core can handle two threads of instructions simultaneously, improving the efficiency of the CPU. As a result, tasks can be processed more quickly, especially in multi-threaded applications. By enabling better utilization of the processor's resources, Hyper-Threading can enhance performance in various computing tasks, such as video editing, gaming, and running virtual machines. However, the actual performance gain can vary depending on the specific workload and software being used.
