Explanation

Clock frequency is one of the most significant factors influencing a computer system's processing performance, clock speed-measured in gigahertz (GHz)-determines how many instruction cycles a processor can perform per second. Higher clock frequencies generally result in faster execution of instructions, leading to improved performance in both single-threaded and multi-threaded workloads. While modern CPUs also rely on core count, cache size, and architecture efficiency, clock frequency remains a primary metric for evaluating raw processing speed.
