Application Note 116 Performance Rating the Cyrix M II-300 Processor APPLICATION NOTE 116 Performance Rating the Cyrix M II-300 Processor Megahertz and Performance In the past, performance of a processor has been measured in megahertz (MHz). The MHz rating simply refers to the clock speed of the processor. If the clock speed is increased, the performance increases for the same type of processor. For different types of processor architectures, clock speed is not a good indicator of comparative performance. For example, one could imagine two processors operating in parallel as one device, and an other device with only a single processor. With both operating at same clock speed, their performance would be markedly different. The best way to compare processors is to directly measure their performance. In a real world situation, this can be done by running the same popular business programs on all processors under test. To ensure consistency, an application bench- mark program should be used that runs these programs using a fixed script. The script should model the steps a typical user would use in the real world. As the benchmark runs, it should navigate through several types of applications, exercising the computer-system components for about an hour. In Cyrix's opinion, an excel- lent program for performing this type of application benchmark testing is Winstone 98 as it conforms to the criteria mentioned above.
