How to Compare Processors

If you are planning on buying a computer, you need to know how to compare processors.  Your computer’s processor is responsible for any function that takes place within your computer. Essentially, the processor acts as the brain of your computer, receiving and sending signals to the different elements of your computer that make it work. This means that comparing processors is probably the single most important thing you can do before making a computer purchase.

In order for your computer to function as quickly as possible, or to operate multiple processes at the same time, your processor has to be capable of handling all of the different requests that are made of it. With this in mind, knowing that you have the right processor for the different things you’ll be asking of your computer is important, and you can make sure that you have the right processor by learning how to compare processors and by prioritizing what is most important to you.

Here are the key things to consider in order to compare processors:

Comparing GigaHertz (GHz)

When you want to compare processors, the biggest thing to compare from processor to processor is the number of GigaHertz or GHz at which the processor is able to operate.

The capability of processors is measured by the number of processes they are able to perform per second. The higher the frequency in GHz the processor is given, the higher the speed of the processor. This translates directly into a higher amount of speed at which your whole computer operates. The GHz affects how quickly windows open when you click on their icons, how quickly your programs initiate when you start them up, and how quickly your computer starts up after it’s been off. 

Comparing Processor Cache

The other key thing you need to look at if you want to know how to compare processors is the cache that your processor is capable of holding.

The processor’s cache is the amount of space that can be taken up through the processor at any specific point in time. This means that the larger the processor’s cache, the higher the number of processes and programs you will be able to run at the same time without the computer being slowed by them.

If your computer’s processor has a limited cache, chances are your computer won’t be able to perform at the same rate of speed of a processor with a larger cache.  This means if you want to have multiple programs (especially memory-heavy programs like Photoshop) open at the same time, you may experience lag problems or other issues.

Comparing Processor Power Requirements

Yet another thing to consider when comparing processors for your computer is the amount of power that your processor requires in order to function properly. This is especially important when your computer is a laptop or notebook computer, because a higher wattage or voltage requirement will drain your computer’s battery much faster than a processor with a lower wattage need. The lower the voltage needed from your computer’s processor, the more efficiently your computer will run and the less heat that will be generated by your computer.
