Consoles are focused on lowest possible cost of their hardware, since they sell to consumers at a loss, or at the best a slim profit. They need their suppliers to give them hardware for bottom dollar. That means you don't get much profit per unit.
Now that doesn't mean AMD is getting screwed, I'm sure they are making money per unit sold, but make no mistake: The reason they got the contracts is they could offer the lowest price and that means a thin profit. So 10 million chips sold in the console is less profit than 10 million sold in a desktop or server or the like.
It is not the grand prize of hardware contracts.
On another note I find it hilarious how fanboys relish in the concept of a competitor doing badly, as if we all wouldn't be more screwed if there was a single company. Personally, I like nVidia GPUs, they work better in my experience. However I'm real, real glad AMD is around. Why? Well if they weren't nVidia could, and would, charge more than they already do, and they wouldn't release new tech as fast.
So if you are an AMD fanboy wishing the death of Intel and nVidia, what you are really saying is "Gee I hope AMD will be able to overcharge me for lower end technology when they have nobody to push them!"
