Intel Hyper-Threading Technology
- Delivers thread-level parallelism on each
processor resulting in more efficient use of processor resources—higher
processing throughput—and improved performance on the multi-threaded software of
today and tomorrow.
Intel Virtualization Technology (VT-x)
- Increasing manageability, security, and
flexibility in IT environments, virtualization technologies like
hardware-assisted Intel Virtualization Technology (Intel VT) combined with
software-based virtualization solutions provide maximum system utilization by
consolidating multiple environments into a single server or PC.
- By abstracting the software away from the underlying hardware, a world of new
usage models opens up that reduce costs, increase management efficiency,
strengthen security, while making your computing infrastructure more resilient
in the event of a disaster.
Intel Virtualization Technology for Directed I/O (VT-d)
- Intel Virtualization Technology for Directed I/O
(VT-d) extends Intel's Virtualization Technology (VT) roadmap by providing
hardware assists for virtualization solution.
- VT-d continues from the existing support for IA-32 (VT-x) and Itanium
processor (VT-i) virtualization adding new support for I/O-device
virtualization.
- Intel VT-d can help end users improve security and reliability of the systems
and also improve performance of I/O devices in virtualized environment.
- These inherently helps IT managers reduce the overall total cost of ownership
by reducing potential down time and increasing productive throughput by better
utilization of the data center resources.
Intel Trusted Execution Technology
- Intel Trusted Execution Technology for safer
computing is a versatile set of hardware extensions to Intel processors and
chipsets that enhance the digital office platform with security capabilities
such as measured launch and protected execution.
- Intel Trusted Execution Technology provides hardware-based mechanisms that
help protect against software-based attacks and protects the confidentiality and
integrity of data stored or created on the client PC.
- It does this by enabling an environment where applications can run within
their own space, protected from all other software on the system.
- These capabilities provide the protection mechanisms, rooted in hardware, that
are necessary to provide trust in the application's execution environment.
- In turn, this can help to protect vital data and processes from being
compromised by malicious software running on the platform.
Intel 64 Architecture
- Intel 64 architecture delivers 64-bit computing
on server, workstation, desktop and mobile platforms when combined with
supporting software.
- Intel 64 architecture improves performance by allowing systems to address more
than 4 GB of both virtual and physical memory.
Enhanced Intel Speedstep Technology
- Enhanced Intel SpeedStep Technology is an advanced means of enabling very high
performance while also meeting the power-conservation needs of mobile systems.
- Conventional Intel SpeedStep Technology switches both voltage and frequency in
tandem between high and low levels in response to processor load.
Execute Disable Bit
- Execute Disable Bit is a hardware-based security
feature that can reduce exposure to viruses and malicious-code attacks and
prevent harmful software from executing and propagating on the server or
network.
- Help protect your customers' business assets and reduce the need for costly
virus-related repairs by building systems with built-in Intel Execute Disable
Bit.
