Intel vPro

https://en.wikipedia.org/wiki/Intel_vPro Intel vPro technology is an umbrella marketing term used by Intel for a large collection of computer hardware technologies, including Hyperthreading, Turbo Boost 3.0, VT-x, VT-d, Trusted Execution Technology (TXT), and Intel Active Management Technology (AMT).[1] When the vPro brand was launched (circa 2007), it was identified primarily with AMT,[2][3] thus some journalists still consider AMT to be the essence of vPro.[4]
