Intel AMT will defiantly enable you to do remote power cycling, and much more. vPro requires two components, a vPro capable CPU (i5 or i7) and chipset. Also, the OEM will need to enable the Intel Management Engine in their BIOS.
The best place to verify if your CPU and chipset selection are vPro capable is at Intel's ARK website.
