Devil's Canyon actually incorporated VT-d and TSX, which the Ci7 4770K didn't had. I suppose I ranted about that long enough for someone to notice it, since before, no one cared. VT-d was considered a useless feature, but besides doing PCI Passthrough to a VM (Which is required if you want to have a full Video Card inside a VM), Windows 10 has a Device Guard that also uses it.It didn't bother 4790K sales...
