Yes, pricing. Most people seem to think Intel is way overcharging for their HEDT chips. If that's really true, then Intel can lower prices easily if necessary.
It's absolutely true.
They are indeed overcharging, but their HEDT lineup is also a completely different set of CPUs from their mainstream product. Since it's a speciality product that is made in more limited quantities, it carries a higher manufacturing cost. So, that's probably some of it, but it's mostly intel milking the enthusiasts, because they have no competition.
Look at this,
6800k is $380 on newegg
6900k is $1050 on newegg
6950x is $1650 on newegg
Adding two cores nearly increases the price by $700! It's insane! The 6900k is easily overpriced by over $500. The margins on those things must be absolutely insane!
They've already sold a bunch, though...so it should in fact be easy to lower the prices if they have been inflated all this time.
But you are assuming they need to... They don't! AMD has had superior CPUs in the past, and even had those CPUs at a lower price. Yet, Intel still didn't lower their prices, because people just ignorantly bought their CPUs anyway. They would lose more money by lowering their prices, than simply ignoring AMD.
