Today’s PC market is dominated by microprocessors from two manufacturers: Intel and Advanced Micro Devices, or AMD. Intel makes Celerons, Pentium 4s and Centrinos (mobile Pentium processor with extra chips to control wireless Internet connections). AMD offers similar products: Athlons, Turions and Semprons.
When you look at a CPU you’ll see specifications on it such as: Intel Pentium Core 2 Duo, 2.66 GHz. This example breaks down as:
Chip brand: Intel
Chip family: Pentium Core 2 Duo
Clockspeed: 2.66 Gigahertz (GHz).
A processor’s clockspeed is simply the rate at which it executes instructions. The abbreviation GHz (gigahertz) is the number of billions of cycles it can perform in one second. Pretty mind boggling.
This measurement has historically been a good way to compare one CPU to another, but it’s not absolute because other parts of a system, like memory, motherboard, and video adapter, also influence performance.

I had purchased AMD 2200+ Athlon Computer from “mdofpc.com” in cheapest price. At first I was concerned with the other review but after reading the sellers feedback from other buyers, I decided to go for it. It arrived fast and worked right out of the box. I had a question about the restore CD and Customer Service was quick and answered my question. The AMD 2200+ Athlon computer is an absolutely great piece. I would recommend this computer to a friend.
