>I have to wonder, with a $690 price tag and a 320 watt power budget who is this chip for?

There used to be a business in selling these ultra performant ST chips to high frequency traders, who'd overclock the absolute crap out of them. Luckily, this is no longer a business. But these kind of products used to be the "waste stream" from them, left overs.

But now, the KS-series intel chips are for slightly insane gamers and overclocking enthusiasts with more money than sense. That's okay, there's a real market segment there. At our work, we buy the 14700K for dev machines like sane people.
