The second term you’ll see is number of cores. You’ll notice a higher clock speed when opening programs, files and exporting photos. The higher the number, the faster the computer (when comparing like-for-like laptop/desktop models). This is measured in gigahertz (GHz, one billion hertz), and tells you how many operations a processor can do each second. When looking at a processor, there are two main figures you’ll see time and time again. In this guide, we’ll explain what different Intel processor models mean and what sort of user they’re best suited for. If you’re buying a computer, chances are it’ll have an Intel processor on board, although a small number come with AMD chips.
