CPU Cycle

A CPU Cycle refers to a single pulse of the computer clock. For example, a 4 Mhz CPU will have 4 million CPU cycles per second. Some instructions take more than one clock cycle. Newer CPUs not only have higher clock ratings, but can also do more with each cycle. CPUs made by AMD are known to do more in each clock cycle than Intel chips, so an AMD chip running at a clock speed may be just as fast as an Intel chip at a much higher clock speed for certain operations.
