Yes, the money Intel makes on the stock is paltry by Intel standards $500 mil ain't gonna make or break Intel.
But what you forget is that Intel is the exclusive provider of the memory controllers for RDRAM on all 820, 840 based motherboards. Imagine if the 820/840 is successfull as BX. How much money does this translate into?
All the money off the Stock plus all the money off the Controllers. Hmmm, sounds like it could be a lot.
All of a sudden Intel does have a vested interest in pushing a technology that may be adequate or inferior. No?
