The usual better, stronger, faster stuff. It uses less power, which is good,
but these systems already were quite good in that regard.
Concerning virtualization, a write through cache of interrupts in the domU's
cpu and it no longer fragments large pages in VT-d. There's a much better
( scroll down to Virtualization Improvements )
I'm fine with buying the hardware and not being able use the above until we get
xen 4.3, as long as it works reliably with a recent kernel and xen 4.2 now. I
suspect it's very likely it will work just fine since everything else, e.g. the
MB, the BIOS ( probably ), etc.. are unchanged.
