There may be some volume discounts that influence some of Apple's choices in low end models, but the Xeon used in the base mac pro has the same list price as the top imac cpus. Its list is also significantly lower than many that show up in the macbook pro. I've linked the same things before, and it never adds up. It's mostly the 8 core and above that are extremely expensive. Their base quad lists for $300. The upward shifts in pricing also tend to occur on the higher end...
