AMD Simultaneous Multithreading (SMT) is a technology developed by AMD that allows a single processor core to handle multiple threads simultaneously. This means that each core can execute two threads at the same time, improving overall performance and efficiency, especially in multi-threaded applications. By sharing resources like execution units and caches, SMT helps to maximize the utilization of the CPU. With SMT, tasks can be processed more quickly, leading to better responsiveness in applications and smoother multitasking. This technology is particularly beneficial for workloads such as gaming, video editing, and data processing, where multiple threads can significantly enhance performance.
