 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.

 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).
