Intel® Virtualization Technology for Directed I/O (VT-d) ‡

Intel® Virtualization Technology for Directed I/O (VT-d) builds upon the existing support for IA-32 (VT-x) and Itanium® processor (VT-i) virtualization by adding new support for I/O-device virtualization. This technology can help improve security and reliability of systems, as well as enhance performance of I/O devices in virtualized environments.

Intel® Virtualization Technology (VT-x) ‡

Intel® Virtualization Technology (VT-x) allows a single hardware platform to function as multiple “virtual” platforms. This technology offers improved manageability by reducing downtime and maintaining productivity through the isolation of computing activities into separate partitions.

Intel® 64 ‡

Intel® 64 architecture enables 64-bit computing on server, workstation, desktop, and mobile platforms when combined with supporting software. This architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.

Idle States

Idle States (C-states) are used to save power when the processor is idle. C0 is the operational state, meaning that the CPU is actively performing tasks. C1 is the first idle state, C2 is the second, and so on, with higher C-states providing more power-saving actions.

Intel® Turbo Boost Technology ‡

Intel® Turbo Boost Technology dynamically increases the processor's frequency as needed by utilizing thermal and power headroom to provide a burst of speed when necessary, while also improving energy efficiency when not in use.

Intel® Hyper-Threading Technology ‡

Intel® Hyper-Threading Technology (Intel® HT Technology) delivers two processing threads per physical core. This allows highly threaded applications to complete tasks more efficiently in parallel, resulting in improved performance.

Instruction Set

An instruction set refers to the basic set of commands and instructions that a microprocessor can understand and execute. The value shown represents which instruction set this processor is compatible with.

Intel vPro® Platform Eligibility ‡

The Intel vPro® platform is a set of hardware and technologies used to build business computing endpoints with premium performance, built-in security, modern manageability, and platform stability.

Intel® VT-x with Extended Page Tables (EPT) ‡

Intel® VT-x with Extended Page Tables (EPT), also known as Second Level Address Translation (SLAT), provides acceleration for memory-intensive virtualized applications. This technology reduces memory and power overhead costs and increases battery life through hardware optimization of page table management.

Enhanced Intel SpeedStep® Technology

Enhanced Intel SpeedStep® Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. This technology utilizes design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.

Intel® Demand Based Switching

Intel® Demand Based Switching is a power-management technology that keeps the applied voltage and clock speed of a microprocessor at the minimum necessary levels until more processing power is required. This technology was previously known as Intel SpeedStep® Technology in the server marketplace.

Intel® Flex Memory Access

Intel® Flex Memory Access allows for easier upgrades by allowing different memory sizes to be populated and remain in dual-channel mode.

Instruction Set Extensions

Instruction Set Extensions are additional instructions that can increase performance when the same operations are performed on multiple data objects. These can include SSE (Streaming SIMD Extensions) and AVX (Advanced Vector Extensions).

Thermal Monitoring Technologies

Thermal Monitoring Technologies protect the processor package and the system from thermal failure through several thermal management features. An on-die Digital Thermal Sensor (DTS) detects the core's temperature, and the thermal management features reduce package power consumption and temperature when necessary to remain within normal operating limits.

Intel® Identity Protection Technology ‡

Intel® Identity Protection Technology is a built-in security token technology that helps protect access to online customer and business data from threats and fraud. This technology provides a hardware-based proof of a unique user’s PC to websites, financial institutions, and network services, verifying that it is not malware attempting to login. Intel® IPT can be used as a key component in two-factor authentication solutions to protect information at websites and business log-ins.

Intel® Transactional Synchronization Extensions

Intel® Transactional Synchronization Extensions (Intel® TSX) are a set of instructions that add hardware transactional memory support to improve performance of multi-threaded software.
