Choosing the best laptop processor

Finding the best laptop processor for your needs is important. As the ‘brain’ of your new laptop, the processor helps you get stuff done. If you multi-task while working or edit video or graphics, prioritise a laptop with a powerful processor. Our guide explains how processors work and helps you to find the best laptop CPU for you.

What is
A processor?

Every computer has a processor – a chip that turns your keystrokes and mouse scrolls into actions. Also known as the CPU (central processing unit), it can handle billions if not trillions of these little decisions every second. And it’s not just your inputs – the CPU must also juggle apps, games and other software while configuring hardware at the same time.

When looking at CPUs, we often talk about cores – the individual units processors are grouped into. Dual-core and quad-core processors are found on many laptops today. Dual and quad refer to the number of cores (two and four). More cores generally mean better performance.

To find the best processor, you need to think about how you’ll use your new laptop.

Basic web browsing and typing require less power.

Browse, stream and run spreadsheets simultaneously, you’ll need more power

Heavy duty tasks like video editing and PC gaming demand the most power

Laptop processor types:
Cores and clock speed

Different laptop processors are designed to suit different people.
For university, working from home, binge watching or creative projects, Intel® Core™ can be a good option.

Laptop processor cores – dual-core, quad-core and more

Intel Core processors boast multiple cores (dual core or quad core). Entry level processors such as Celeron and Pentium will lack the power you need.

More cores multiply processing power. So your laptop will be more powerful and able to handle more tasks at once (11th Gen delivers over 20% faster work productivity in LG gram laptops). This means smoother multitasking when:

  • Working from home across multiple apps
  • On email and video calls simultaneously
  • Watching Netflix and browsing the web
  • Editing photos and uploading blogs

Clock speed

To know how much a processor can handle, check its clock speed. Measured in gigahertz (GHz), this figure reveals how many operations a processor runs every second. The latest 11th Gen Intel Core processors can reach up to 4.8Ghz Turbo clock speeds*.

Intel Core i5 or i7?
Which processor do I need?

Intel Core laptops are available in different variants – including the i5 and i7. These are designed to complement the different ways we work with our laptops. Finding the best Intel processor for you depends on how you’ll use your laptop.


The i5 is built for busy browsing and smooth multitasking. Pump out playlists while working from home. Chair Zoom calls while scouring spreadsheets. Binge-watch Netflix while researching essays on multiple tabs. It's the ultimate all-rounder.


Creatives and gamers demand more. Edit video, design graphics and re-touch photos with the power of Intel Core i7. It delivers 2.7 times faster content creation on LG gram laptops. Get 2 times faster game playing and streaming and enjoy AAA-level games.

Intel processor
Generations explained

Intel Core has been at the heart of laptop technology for more than a decade. Successive generations have produced more efficient and capable processor chips. When you’re comparing prices on laptops it’s worth considering…

  • When the model in question was released
  • The category they're part of

Intel processor generations

The Core series was launched in 2006 to replace the Pentium brand, with the first dual-core processor. In the years since, Intel has developed new generations of the Core series.

The latest 11th Gen Intel Core processors, deliver faster, more powerful performance.

  • Power up to 4.8Ghz Turbo clock speeds
  • The fastest SSD ( Intel Optane H10)
  • Single-cable connection with Thunderbolt 4
  • Video calls powered by Wi-Fi 6

Intel Iris X

Intel Iris X deliver discrete level graphics. Play Full HD games at 30fps.

Intel® Evo™

Get to work fast. Your laptop wakes instantly, is ultra-responsive and boasts all-day battery life.

Product line suffix

Another thing to check when browsing for a new laptop is the suffix. This is a single letter attributed to the processor on some laptops. The letters include T, K and U.

  • K signifies the highest processing power in the whole line
  • T uses less power than a non-suffix, but sacrifices performance
  • U usually indicates the very lowest

Why check? It’s important to check the product line suffix, as this tells you how much you can expect to get done on your laptop.

How to work out your intel processor

You can identify what processor you’re currently using by running a search on Windows or Mac. Visit Intel support for a step-by-step guide. Learn which generation your computer is, as well as which prefix (if any) it employs.

Best fastest laptops
Boast powerful processors

When you’re looking for the best fastest laptops, Core i7 processors give you plenty of power thanks to their ability to increase core count. But fast laptops are about more than processors.

Choose more RAM

the short-term memory that enables your laptop to access information it needs more quickly.

Opt for an SSD

SSDs (solid state drives) run software faster than ordinary hard drives, meaning a smoother boot-up every time.

What laptop
Processor to buy?

The best laptop CPU for you depends on how you plan to use it. Sure, you want Intel 11th Gen, but which classification?

Consider an i5 for work and university - whether working from home or away. An i5 is also ideal for a busy family. Big on gaming or creative projects like video editing and music composition? An i7 is for you.
