Use MHz to measure computer performance, which refers to the computer's "CPU clock frequency". Clock frequency refers to the basic frequency of the clock in a synchronous circuit. It is measured in "several cycles per second" and the unit of measurement is "Hertz"; the corresponding units are: Hz (hertz), kHz (kilohertz), MHz (megahertz). Hertz), GHz (Gigahertz).

Using MHz to measure computer performance, it refers to the computer's "CPU clock frequency".

The clock frequency of the CPU is the main frequency. The operation of the computer is executed step by step under the control of the clock signal. Each clock signal cycle completes one step of the operation. The level of the clock frequency reflects to a large extent The speed of the CPU.

Clock frequency (also translated as: clock frequency speed, English: clock rate) refers to the basic frequency of the clock in the synchronous circuit, which is "several cycles per second" To measure, the measurement unit adopts the SI unit Hertz (Hz). It is an important indicator for evaluating CPU performance. Generally speaking, the larger the main frequency digital value, the better.

Frequency is a measurement name that describes the number of pulses that appear in a periodic cyclic signal (including pulse signal) per unit time; the standard measurement unit of frequency is Hz (Hertz). The system clock in a computer is a typical pulse signal generator with a fairly accurate and stable frequency. Frequency is represented by "f" in mathematical expressions, and its corresponding units are: Hz (hertz), kHz (kilohertz), MHz (megahertz), GHz [gigahertz (1 gigahertz = 1000000000)].

Where 1GHz=1000MHz, 1MHz=1000kHz, 1kHz=1000Hz. The time unit for calculating the pulse signal period and the corresponding conversion relationship are: s (second), ms (millisecond), μs (microsecond), ns (nanosecond), where: 1s=1000ms, 1 ms=1000μs, 1μs=1000ns .
