MERGER - AMD+DELL!

A merger is when two companies combine. After the merger only one company would exist.

What you are referring to is a possible agreement between Dell and AMD that would involve Dell purchasing AMD processors and using them in their products.

Also, as others have said: Unless the news article is from today, it has probably already been discussed.
 
The next thing you'll say is that oil and water can be mixed.

It would make no sense at all for Dell to buy a Company that makes a processor they've never used.
