Computers are extremely complicated. Cores, speed, processing units, gigahertz, what does it all mean?

When you are on the lookout for a new laptop or computer, the CPU or central processing unit is the most important part. One that you should definitely prioritize. Unfortunately, they come with a lot of jargon.

In this article, we will explain what a processor is, what it does, and specifically, we are going to explain what a Quad-Core Processor is.

What is a Processor?

Inside your computer is a number of parts. All of them have their part to play in the day-day running of your computer.

The most important part is called the processor which has multiple components. Your processor makes thousands of decisions every single second. These decisions allow all of the parts of your computer to communicate and work.

The power and quality of your processor are measured in a number of ways. Two of the most common indicators are clock speed and the number of cores.

Clock speed is the number of decisions or processes that your CPU can undertake per second. This number is measured in GHz. 1GHz is 1000 processes per second.

The higher the speed, the more decisions your computer can make every second and the smoother your computer will run when you start doing demanding work. The processor speed that you need depends on the tasks that you will be doing.

A core is essentially a component of the CPU. Old processors used to have a single core. That meant that the processor could only undertake one single task at a time.

Multi-core processors are what we use today. Dual-core processors can work on 2 separate tasks; a quad-core processor can work on 4 separate tasks, as it has four cores.

Multiple cores allow processors to work at a much more efficient rate. Twin-core CPUs processor will allow you to tackle most normal computing tasks with ease.

A quad-core processor will allow your computer to undertake more challenging tasks like gaming or 3D modeling.

Remember that many cores do not equal high performance; you will need your processor to be strong in other areas too.

One thing you need to bear in mind when deciding upon a processor is power consumption. A quad-core processor is much more powerful but requires a lot more power to run. This means that in laptops, you will have less battery, and desktops will require a stronger power supply.

Both dual-core CPUs and quad-core processors produce more heat than a single-core processor. This means you will need to consider what cooling solutions your laptop or computer will need in order to keep the CPU at an optimum processing temperature. Single-core processors produce very little heat, so it may be something you have never had to consider before.

The number of cores does not reflect the quality of the processor. Newer dual-core processors are often stronger than old quad-core processors from previous generations.

Our advice would be to buy a processor from the newest generation. If your budget only allows for a dual-core processor from the newest generation, you may still be better off than buying an older quad-core processor.

Again, do not get hung up on the number of cores. Prioritize newer generations and buy as high up in that line as you can afford.

Installing a quad-core CPU into your PC or buying a laptop with one already inside is an easy way to make sure your computing power is high enough for gaming and photo/video editing. For these programs, having four cores is a massive benefit.

If you do not game or edit, it may not be worth the cost to upgrade to multiple cores as you might not even notice a difference.

If you are using an old laptop and want a faster system in general, increasing the number of cores that your system can use is an easy way to make your computer faster.
