I believe only LGA-1156 was supposed to be the traditional desktop - dual channel, like for ages. HEDT started with 3 channel boards at same 4C (= same core count as desktop), then grew over time.

Except that no matter what they try to show, Intel sells more chips and most of the time their next chip outperforms the last AMD chip. I'll say it again and again, AMD needs to get their next chip ...
