The processor is the brain of a computer — but understanding the difference between processors requires a lot of brainpower of your own!
Intel hasn’t made it any easier for customers with their strange naming schemes, and the question we get asked most often is: What’s the difference between an i3, i5, or i7 processor? Which one should I buy?
It’s time to demystify that. In this article, we won’t be touching on Intel’s other processors like the Pentium series or the new laptop-centric Core M series. They’re good in their own right, but the Core series is the most popular and confusing, so let’s just focus on that.
Understanding the Model Numbers
Purely speaking, it’s very simple. An Intel Core i7 is better than a Core i5, which in turn is better than a Core i3. The trouble is knowing what to expect within each tier. Things go a little deeper.
First, i7 does not mean a seven-core processor! These are just names to indicate relative performance.
Typically, the Core i3 series has only dual-core processors, while the Core i5 and Core i7 series have both dual-core and quad-core processors. Quad-cores are usually better than dual-cores, but don’t worry about that just yet.
