Intel's Hyper-Threading is a technology that allows a single physical processor core to act like two separate logical cores. This means that each core can handle two threads simultaneously, improving the efficiency of the CPU. As a result, applications that support multi-threading can run faster and more smoothly, making better use of the processor's capabilities. By enabling multiple threads to be processed at once, Hyper-Threading helps improve overall system performance, especially in tasks like video editing, gaming, and running virtual machines. This technology is commonly found in many of Intel's modern processors, enhancing their ability to multitask effectively.
