120-447: The mid-1990s as a method of comparing their x86 processors to those of rival Intel . The idea was to consider instructions per cycle (IPC) in addition to the clock speed, so that the processors become comparable with Intel's Pentium that had a higher clock speed with overall lower IPC. The first use of the PR system was in 1995, when AMD used it to assert that their AMD 5x86 processor

Later that year, Cyrix also adopted the PR system for its 6x86 and 6x86MX line of processors. These processors were faster than Pentiums of the same speed in some benchmarks, so Cyrix gave them a Performance Rating faster than their clock speed. Some AMD K5 models also use the PR system. AMD initially branded its AMD K6 processors with
