As a computer repair technician, I run across many questions regarding a laptop or desktop’s performance. Computers are getting more and more complex and deciding on the right one can make a big difference on how satisfied you will be. It is easy to think you have the best one picked out because the hard drive is bigger, but choosing is no longer based on the biggest numbers. There are three main factors to determine the speed of a computer.
The RAM or memory
Also called random access memory, RAM is a temporary storage location for the operating system and programs. This helps each program to run smoothly and quickly.
The hard drive
The storage location of everything including the operating system.
What is CPU? CPU stands for central processing unit. The CPU’s function is the brain or thinking station of the computer, all data runs through the CPU.
If any one of these is slow then the entire computer will be slow
Today we will discuss CPUs in depth to help you decide on which computer you want to purchase. We will define some common terminology regarding processors. When you purchase a computer, you will see some common terms listed below.
What is GHz and base GHz?
The GHz or base GHz is referred to gigahertz, gigahertz is a frequency just like megahertz or hertz. Simply put the higher the gigahertz the higher the frequency and the higher the frequency the more data can pass through the device. The higher the GHz the faster the processor is. But there is one important factor here, most processors only advertise the base GHz which is the lowest operating performance of the processor so when you see the GHz on a processor label it is the base GHz not the fastest GHz it can go. All newer processors have a variable GHz performance to conserve power consumption. On the label below this is a example of the base GHz.
