What is a Processor?

Find out everything you need to know about processors, including what they are, and which one is best for you with our helpful guide.

A processor acts like the brain of your computer. It’s responsible for handling every task you ask your computer to do, and takes care of all the behind-the-scenes work that makes your computer run smoothly. People sometimes refer to the processor as the CPU, which stands for Central Processing Unit.

Get the lowdown on processors

A computer’s processor is all about speed and how quickly and efficiently it can open and run your programs. You may hear people talk about the amount of ‘cores’ a processor has, a core is essentially a special unit that sits inside your processor. As a simple rule of thumb, the more cores your processor has, the more things you’ll be able to do simultaneously. Find out more about these clever cores below.

When you’re looking for your perfect computing companion, you’ll come across two stand out names for processors, Intel (the market leaders) and AMD. We’ve got tons of information at the bottom of this page to help you choose your perfect processor.

Cut to the core!

If your computer’s processor has multiple cores, it means it shares the workload of opening and running your programs between a couple or more of those little units we mentioned earlier. Like the old adage, many hands make light work, the cores simply split your computers to do list down between them, so that they can operate your programs more efficiently.

So you’ll be able to do things like this:

• Play music whilst editing your holiday snaps
• Download a movie whilst video chatting your friends abroad
• Have multiple internet browser tabs open at the same time whilst finishing that report

Most computers have either a dual-core (2 cores) or quad-core (4 cores) processor. To find out how many cores your computer’s processor has, check out our specification list on our product pages.

Intel processors

Intel are the processor heavyweights of the computing world. Their products are designed to keep up with your lifestyle, so you can multitask without even knowing it.

Here’s a quick breakdown of Intel’s best processors and all of the exciting things they can do for you.

Core M, i3, i5, i7

If you’re looking to future proof your computer you can’t go wrong with these processors. They give you the ultimate Intel experience, they’re quick, powerful and they let you open and run lots of different programs together. To make sure your processor can keep up with any digital advancements over the next few years, we recommend choosing either an i5 or i7 processor.

Pentium & Celeron

Both of these processor types offer quick web browsing speeds and smooth operation when using apps. They’re also great for people who like to dabble in casual gaming here and there.


Intel Atom processors are a great choice for tablets, laptops and 2 in 1’s because they not only offer fast loading speeds, they can also help prolong your battery life, making them a great choice for people looking for something that’s more portable. They are Intel’s entry level offering though, so they’re not as powerful as their Core range.
