Can someone end this argument I'm having please.

Now I thought AMD support HT2.0 with their current Opterons and that you can get the AMD-8132 chipset in servers which support PCI-X 2.0 and HT2.0.

A guy at work has stated that AMD have never used HT2.0 and that they are still using HT 1.x, which I think is bollxxxx - (to put it very mildly, wrong).

Does anyone know factually?
