Mips

MIPS

Acronym for million instructions per second. A old measure of a computer's speed and power, MIPS measures roughly the number of machine instructions that a computer can execute in one second. However, different instructions require more or less time than others, and there is no standard method for measuring MIPS. In addition, MIPS refers only to the CPU speed, whereas real applications are generally limited by other factors, such as I/O speed. A machine with a high MIPS rating, therefore, might not run a particular application any faster than a machine with a low MIPS rating. For all these reasons, MIPS ratings are not used often anymore. In fact, some people jokingly claim that MIPS really stands for Meaningless Indicator of Performance.

Despite these problems, a MIPS rating can give you a general idea of a computer's speed. The IBM PC/XT computer, for example, is rated at ¼ MIPS, while Pentium-based PCs run at over 100 MIPS.

MIPS (Million Instructions Per Second) | |

Stands for "Million Instructions Per Second." It is a method of measuring the raw speed of a computer's processor. Since the MIPS measurement doesn't take into account other factors such as the computer's I/O speed or processor architecture, it isn't always a fair way to measure the performance of a computer. For example, a computer rated at 100 MIPS may be able to computer certain functions faster than another computer rated at 120 MIPS.

The MIPS measurement has been used by computer manufacturers like IBM to measure the "cost of computing." The value of computers is determined in MIPS per dollar. Interestingly, the value of computers in MIPS per dollar has steadily doubled on an annual basis for the last couple of decades.
