This thread is flame bait, but I'll post anyway...
The answer to your question... They aren't paying them anything...
I'm a big AMD fan. That said, however, it isn't hard for me to see why companies like Dell do business with Intel. For one, Intel cuts them sweet price deals. For another, Intel actually informs their customers what they are doing, both now, and for the next 4 to 8 quarters. (I won't even mention HP, because HP and Compaq are now one big company and Compaq has a long history with AMD.)
AMD is cheap and their performance is good. I love them, but their PR stinks. They won't/can't tell anyone what they will be doing this time next year, what sockets will be around, what chips are actually going to be on the market, etc, etc, etc. To be blunt, I don't think AMD knows what they're going to be doing 12 months from now. Intel knows what they are currently doing, and what they will be doing 12 months from now and 24 months from now. Because they are good business people, they share this information, so their customers know what to expect and how to plan for the future.
Intel knows how to treat corporate customers. AMD doesn't.
