 Turbo Boost 
Technology
Intel
®
 Turbo Boost Technology is a way to automatically run the processor core 
faster than the marked frequency if the part is operating under power, 
temperature, and current specifications limits of the Thermal Design Power 
(TDP). This results in increased performance of both single and multi-threaded 
applications.

 Trusted Execution 
Technology (Intel
®
 TXT)
Intel
®
 Trusted Execution Technology uses features in processor, chipset and TPM 
to enable more secure and robust systems against software attacks.
Intel

 Virtualization 
Technology (Intel
®
 VT)
Processor Virtualization which when used in conjunction with Virtual Machine 
Monitor software enables multiple, robust independent software environments 
inside a single platform.
Intel
®
 VT-d
Intel
®
 Virtualization Technology (Intel
®
 VT) for Directed I/O. Intel VT-d is a 
hardware assist, under system software (Virtual Machine Manager or OS) 
control, for enabling I/O device Virtualization. Intel VT-d also brings robust 
security by providing protection from errant DMAs by using DMA remapping, a 
key feature of Intel VT-d.
Integrated Heat Spreader 
(IHS)
A component of the processor package used to enhance the thermal 
performance of the package. Component thermal solutions interface with the 
processor at the IHS surface.
Jitter
Any timing variation of a transition edge or edges from the defined Unit Interval 
(UI).
Intel Xeon processor E7 v2 
product familyr
Intel’s 22-nm process based product used in Intel Xeon processor E7 v2 product 
family-based platform.
