Supported Technologies
3.3.1.1
Intel® 64 Instruction Set Architecture
64-bit memory extensions to the IA-32 architecture. Further details on Intel 64 architecture and
programming model can be found at
http://developer.intel.com/technology/intel64/
3.3.1.2
Intel® Hyper-Threading Technology (Intel® HT Technology)
The processor supports Intel® HT Technology, which allows an execution core to function as two logical
processors. While some execution resources such as caches, execution units, and buses are shared, each
logical processor has its own architectural state with its own set of general-purpose registers and control
registers. This feature must be enabled via the BIOS and requires operating system support.
3.3.1.3
Enhanced Intel SpeedStep® Technology
Processors in the Fifth Generation Intel® Core™ Processor Family support Enhanced Intel SpeedStep®
Technology. The processors support multiple performance states, which allows the system to dynamically
adjust processor voltage and core frequency as needed to enable decreased power consumption and
decreased heat production. All controls for transitioning between states are centralized within the processor,
allowing for an increased frequency of transitions for more effective operation.
The Enhanced Intel SpeedStep Technology feature may be enabled/disabled by an option on the Processor
Configuration Setup screen. By default Enhanced Intel SpeedStep Technology is enabled. If Enhanced Intel
SpeedStep Technology is disabled, then the processor speed is set to the processor’s maximum TDP core
frequency (nominal rated frequency).
3.3.1.4
Intel® Turbo Boost Technology 2.0
Intel®
Turbo Boost Technology is featured on all processors in the Fifth Generation Intel® Core™ Processor
Family. Intel
Turbo Boost Technology opportunistically and automatically allows the processor to run faster
than the marked frequency if the processor is operating below power, temperature, and current limits. This
results in increased performance for both multi-threaded and single-threaded workloads.
3.3.1.5
Intel® Virtualization Technology for IA-32, Intel® 64 and Intel® Architecture (Intel® VT-x)
Intel® Virtualization Technology for IA-32, Intel® 64 and Intel® Architecture (Intel® VT-x) provides hardware
support in the core to improve performance and robustness for virtualization. Intel VT-x specifications and
functional descriptions are included in the Intel 64 and IA-32 Architectures Software Developer’s Manual.
3.3.1.6
Intel® Virtualization Technology for Directed I/O (Intel® VT-d)
Intel® Virtualization Technology for Directed I/O (Intel® VT-d) provides hardware support in the core and
uncore implementations to improve I/O virtualization performance and robustness.
