1. Why do the Core 2 Quad Yorkfield processors cost more than the Core i7? (Core 2 links: here and here. Core i7 link: here)
2. Why does the Core 2 Extreme processor cost more than the Core i7 Extreme? (Core 2 Extreme: here; Core i7 Extreme: here)
I ask because it was my understanding that i7 was the latest and greatest processor technology and that its hyperthreading and increased number of transistors allow it to outperform any Core 2 Quad processor. Clearly this isn't the case if Intel still wants more money for some of their Core 2 processors? A technical explanation would be great!
Thanks!
