Difference between an Intel Core i3, i5 and i7 processor


In this post we are going to tell you the difference between an Intel Core i3, i5 and i7 processor. These processors have been around for over a year now, but some buyers still get stumped when ever they attempt to build their own systems and are forced to choose among the three.

In general speaking, core i7 is better than i5 which is in turn better than i3. Neither i7 have 7 cores nor i3 have three cores. These numbers simply indicate their relative processing powers.

Their relative levels of processing power are also signified by their Intel Processor Star Ratings, which are based on a collection of criteria involving their number of cores, clock speed (GHz), size of cache, as well as some new Intel technologies like Turbo Boost and Hyper-Threading.

Core i3s are rated with 3 stars, i5s have 4 stars and i7s have 5. If you're wondering why the ratings start with three, well they actually don't. The entry-level Intel processors- Celeron and Pentium- get one and two stars respectively.
