The following result is obtained by our expert's opinion: Generally clock speed plays the most important role in the speed and performance of a processor. But currently, Intel came with a great marketing plan where it is difficult to see any major difference in the clock speed of any 2 families of the processor. Hence, here you should watch for the number of cores in the processor and also look for turbo booster. Turbo Booster processors are better. Also, inspect that is it a performance processor or normal? Performance processors are better.
