Buyers Guide: Computer vs Laptop

Computer or Laptop? Pre-built or home made? We breaks down everything you need to know before choosing your next PC.

When buying a computer you will be faced with two options: a desktop PC or a laptop. Here’s what you need to know before you drop the cash on your next PC, regardless of whether you’re more interested in something portable or something powerful.

What’s the difference between a desktop and a laptop?

A desktop PC is one that will reside on a desk in your office or bedroom. It will come with separate parts — usually a tower, which contains the brains and muscle of the PC alongside the display monitor, keyboard and mouse.

The biggest difference between a desktop and laptop is that laptops are limited by the size of the battery inside them. Most laptops have a battery that can today last anywhere between an average of six hours going up to twelve or more, depending on the type of programs you use.

Speed

In the old days, if you wanted a fast computer, you had to buy a desktop PC. Fortunately, in more recent times, the gap between desktop PC’s and laptops in general and gaming performance has closed considerably, with manufacturers offering most mid to high-end dedicated gaming hardware in laptop form.

Specifications

The key specifications to look for when buying a desktop PC or a laptop are the CPU, RAM (memory), graphics card and hard drive.

The CPU is essentially the brain of your computer; the RAM is the space where all your programs will be loaded (the more RAM you have, the more programs you can load); the graphics card determines how well your computer will play games; and the hard drive determines how many programs, documents, videos and other files you will be able to store on your computer.

Screen size and resolution

When buying a laptop, you will need to decide what size screen will be suitable for your needs.

Laptops between 12 and 15 inches offer a good balance of portability and power, with 15 inch laptops today providing enough space to pack powerful parts into a relatively lightweight frame.
