Intel's Haswell lineup takes market segmentation to a pretty extreme level. There's 22 Haswell cpu models on the lineup. They have clearly targeted some chips for gamers and others for server use.

You can't get an "unlocked" cpu with virtualization, but you can get the same chip locked with virtualization extensions. I guess the purpose is to avoid customers buying unlocked chips and overclock them for a diy server setup and get them to buy the more expensive server chips.

Process binning I can understand, it's a way to try to improve the silicon yield. But artificial crippling, when taken to this kind of extremes feels a bit dishonest to me. But that's just the way the semiconductor industry works, I guess.
