How Is A Processors Clock Speed Measured?
In prehistoric days when the 80486 ruled technology, the clock speed of a processor measured in either Megahertz (MHz). At present day low class processors are measured in Gigahertz (Ghz) for medium to high end processors. For comparison purposes, the first commercial PC released in 1981 came equipped with a processor running at a 2 MHz clock speed (which allowed for 2,000,000 cycles per second to be executed by the processor). A processor chip running at 100 MHz can execute more than 100 million cycles per second). At present day, a standard Pentium IV class processor designed with a 3GHz processor chip, can execute more than three billion cycles per second, a far difference from the first processors engineered.
