Which one of the following measures the speed of the CPU?

Answer 1

CPU Speed is meshed in Gigahertz. For example: Abbreviation for gigahertz. One GHz represents 1 billion cycles per second. The speed of microprocessors, called the clock speed, often is measured in gigahertz. For example, a microprocessor that runs at 200 GHz executes 200 billion cycles per second.

Answer 2

The clock speed of a processor typically is not measured; rather it is set by the hardware on the motherboard that holds it. It is possible to measure the processor speed by having a routine that takes a specific number of machine cycles to execute, running that routine repeatedly for a fixed length of time (measured by the real-time controller chip on the motherboard) and counting how many times it completes. From that, you can determine the number of machine cycles per unit time, and this translates very simply into a number of machine cycles per second. This is usually expressed in terms of hertz, rather than cycles, a practice that dates back to the days when a machine cycle occurred every time the system clock ticked, so the system clock speed in hertz was the processor speed. Modern chips have speeds measured in gigahertz (GHz), thousands of millions of machine cycles per second.

Some processors take the clock provided to them by a clock source on the board and multiply the speed internally to generate a faster internal clock speed, while others, as indicated above use the board's clock directly.

As a hardware guy, I'd use an oscilloscope to look at the clock signal and most digital oscilloscopes have a frequency function built in. Oscilloscopes can also "zoom in" on a single period and measure the frequency that way (frequency = 1 / period). These are good for fairly accurate approximations of the clock frequency. Other possibilities are using a precision digital frequency counter which counts the number of pulses over a longer period of time (several seconds), then averages the number of pulses over that period of time.

Answer 3

Clock speed is usually measured in MHz (megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses per second).

Answer 4

Clock speed is usually measured in Gigahertz. The standard now days is around 3.
