WebJul 6, 2024 · CPU clock speed, or clock rate, is measured in Hertz — generally in gigahertz, or GHz. A CPU’s clock speed rate is a measure of how many clock cycles a CPU can perform per second. For example, a CPU with a clock rate of 1.8 GHz can perform 1,800,000,000 clock cycles per second. This seems simple on its face. WebClock speed is measured in hertz. The higher the clock speed, the greater the number of instructions that can be performed in any given moment of time. In the 1980s, processors commonly ran... chrome like paint
