So you’re ready to buy a laptop, you have your budget all set, but somehow you can’t just decide on which laptop to get. You’ve probably seen the Intel Core i3 laptop, Core i5, or even the Core i7, and you’re asking yourself… “What does this even mean?” Well, guess what? I’ve got you.  

In this article, I’m going to unravel the “mystery” that is Intel’s “Core i3” “Core i5” or “Core i7” also known as Processors. 

But first, a little lesson. 

The Processor is the brain of any computer that controls its operations. Intel Core processors were birthed in 2006 after unseating the Pentium line that was Intel’s leading high-end processors. 

There are 2 main terms you will always run into when looking at processors. The first is Clock Speed (measured in GHz), and as the name suggests, this typically tells you how many operations a processor can carry out per second. So, the higher the number of GHz, the faster the computer, which means your files, programs, etc. can open way faster. 

The second term is the Cores. Older laptop/desktop chips have dual-core (2) or quad-core (4), while newer models have 6 or 8 cores. Put in simpler terms, the more the cores, the more tasks (a.k.a threads) it can perform at the same time. 

Now let’s get into it.

Core i3

This is where the lineup of Core processors start. Most Core i3 laptops have mostly 2 cores (except Intel’s 8th Gen Core i3 “Coffee Lake” CPUs), which means the number of tasks (threads) it can perform comfortably at the same time, is low. They also have lower cache sizes Let’s take a look at the Lenovo Ideapad, it’s light and suitable for everyday simple tasks like browsing or creating PowerPoint presentations. Core i3 laptops are also very budget-friendly. So, if you’re a student or just need an easygoing, simple laptop then one with a Core i3 is the way to go.

Core i5

These perform better than Core i3 laptops. They have faster average Clock Speeds and a higher number of Cores that makes handling more demanding tasks easier as opposed to Core i3 laptops. This HP Notebook comes to mind; it gets the job done without a lot of hassle and has a 3.6 GHz processing speed. A lot of the Core i5 processor lineup has generally had 4 cores, but that has changed recently and can be seen in the 9th Gen Coffee Lake refresh family that has 6 cores. This delivers a decent performance when it comes to handling multiple tasks.

Core i7

With faster average clock speeds and additional cores, the Core i7 processors are way better than the i3s and i5s. If you’re a gamer or content creator, a Core i7 laptop or higher is for you. Some modern versions have up to 8 cores with Clock Speeds that range up to 3.6GHz.

Now that we’ve broken down what Core i3, i5, and i7 means, go ahead and visit www.dreamworksdirect.com to buy your favorite laptop. 

Tl;dr 

Core i7 is better than Core i5, which in turn is better than Core i3. A Core i3 would be suitable for simple or basic tasks only while a Core i5 handles most tasks well without unnecessary buffering. A Core i7 provides excellent performance for high-level tasks.
