Intel AKA Intel Corperation have been around pretty much since the dawn of time or 1968 to be exact. The chances are you have heard of them as they are kind of a big deal, employing over 100,000 people and a revenue of over 40 billion pounds. Intel are known for making processors and if you have ever owned a computer before the chances are it had an Intel CPU inside. As well as Processors they do also get involved with NAND flash memory and software but this is only a very small amount of their trade.
When you order a new PC it will pretty much come with either an AMD or Intel CPU and thankfully both brands are pretty good. Granted they are guilty of some poorly priced or poorly performing CPU's but they generally are in the Server/Netork platforms and anything you find on our site is considered a "good processor".
Intel offer 3 years or more on their CPU manufacturer warranty.
