Notes:
Intel HT Technology (Hyper Threading Technology) is a performance feature which allows one core on
the processor to appear like 2 cores to the operating system. This doubles the execution resources
available to the O/S, which potentially increases the performance of your overall system.
Intel VT-x Technology (Virtualization Technology) Previously codenamed "Vanderpool", VT-x represents
Intel's technology for virtualization on the x86 platform. In order to support “Virtualization Technology”
the CPU must support VT-x and the BIOS setting “Intel Virtualization Technology” must be enabled.
Intel SMX Technology (Safer Mode Extensions Technology) is a part of the Trusted Execution
Technology.
