What does preformance rate be determined?

I go to this site:http://www.systemrequirementslab.com/. When I used it it sayed You Have: 1.66 GHz Performance Rated at 3.37 GHz(describing my CPU, an Intel Core 2 Duo t5500). What does the Performance Rated part close-fisted?

What does preformance rate be determined?

Basically since you have two cores respectively running at a low clock speed yet sharing the nouns there is no really accurate approach to rate the performance due to differences surrounded by artistry between cpu manufacturers. To construct up for this the dual core CPU's processing power is measured in teraflops (trillions of processs per second) and afterwards converted into GHz to make dual core speed ratings far easyer to dechipher to the average user because it accounts for both processor cores and their contribution to proformance. This conversion is simply set as the processors Proformance Rating.
