SamprasFan,
You've actually got it all wrong.
Intel pays much less for developing their chips than AMD does. Intel has roughly 80% market share, AMD 20%. Therefore, even if Intel only sold processors, they'd have to spend four times as much as AMD for the cost per processor to be the same. As you saw from the budgets, it's not even close to that.
Both spend money on graphics cards, but Intel supports three different processors, AMD just one. There are derivatives for both, but Intel supports the Core line, Atom, and Itanium which are all very clearly different.
Intel also spends money on software. A lot in fact. They spend money on motherboards too.
So, the amount of money spent on development per processor is much less for Intel than it is for AMD. Also, Intel does not pay a royalty to AMD, AMD pays it to Intel.
So, the cost of making a Phenom II is higher than the i7, unless yields are terrible for Intel, which I have not heard. In any event that would pass pretty quickly, and would have by now.
So, i7 is much faster per cycle, clocks higher, uses less power under load, and is cheaper to make. It's really a good thing Intel overprices their products, or AMD would be out of business.
