Introduction

The Core i5 is a CPU series manufactured by Intel aimed at mid-range computers. In this tutorial, we will present a series of quick reference tables for you to compare the main differences between all models released to date.
By the way, the correct name of this line of processors is “Core i5,” not “Intel i5.”
Currently, there are four different generations of Core i5 processors available. In the table below, we describe the main differences between these generations.
