When you finally decided to buy a new computer and eventually gather the necessary amount of money to do so, you still have to face the complex denomination of the computer processors provided by Intel.
The innovation of these products brought along serious changes in the denomination of processors hence a lot of questions arise from simple user regarding the characteristics of i3, i5 and i7 processors and making the correct distinction between them.
The main differences between these three processors are to be found by analyzing their number of cores, available memory, built-in processes and clock speed. The problem is rooted by the discrepancy between the values of these characteristics and the numbers included in the denomination of models.
The essential information everyone should know is that i3 processors have 2 cores, i5 processors can have either 2 or 4 cores, while i7 processors can have up to 6 cores, all of these being determined by the model one uses. In order to correctly identify the actual clock speed of a processor, one must be aware of actual number of cores the target processor has. Therefore one must multiply the number of cores with the specified clock speed to understand the real hierarchy between these three models. To make it crystal clear, this is the explanation for the fact that an i7 with a 1.7 GHz clock speed and 4 cores has a better performance (and is more expensive) than an i3 with 2.7 GHz clock speed and 2 cores.
