Intel® Turbo Boost Technology
Intel® Turbo Boost Technology dynamically increases processor frequency when needed while taking advantage of additional temperature and power capacity to provide acceleration and reduce power consumption when needed.
Intel® Hyper-Threading Technology
Intel® Hyper-Threading Technology provides two processing threads for each physical core. Applications with a large number of threads can perform more operations in parallel, completing tasks in less time.
Intel® Virtualization Technology
Intel® Virtualization Technology (VT-x) allows a single hardware platform to act as multiple "virtual" platforms. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing tasks into separate partitions.
Intel® Virtualization Technology for Directed I/O
Intel® Virtualization Technology for Directed I/O (VT-d) adds support for I/O device virtualization to existing virtualization support for the IA-32 (VT-x) and Itanium® (VT-i) platforms. OR. Intel VT-d enables users to improve system security and reliability and increase I/O device performance in virtualized environments.
Intel® VT-x with Extended Page Tables
Intel® VT-x with Extended Page Tables (EPT), also known as Second Level Address Translation (SLAT), provides acceleration for memory-intensive virtualized applications. Extended Page Tables on Intel® Virtualization Technology platforms reduces power consumption, memory overhead, and increases battery life through hardware optimization of page table management.
Intel® 64
Intel® 64 architecture makes 64-bit computing available on server, workstation, desktop and mobile platforms when paired with supporting software¹. Intel 64 architecture offers a performance boost by allowing systems to use over 4GB of virtual and physical memory.
Instruction set
Instruction set refers to the basic set of commands and instructions that a microprocessor can recognize and execute. The indicated value represents the Intel instruction set with which the processor is compatible.
Instruction set extensions
Instruction set extensions are additional instructions that can improve performance when performing the same operations for multiple data objects. May include SSE (Streaming SIMD Extensions) and AVX (Advanced Vector Extensions).
Idle states
Idle states (C-states) are used to reduce power consumption when the processor is idle. C0 is the operational state and indicates that the CPU is performing useful operations. C1 is the first idle state, C2 the second, and so on. The more actions are taken to reduce energy consumption, the higher the number of C states will be.
Advanced Intel SpeedStep® technology
Advanced Intel SpeedStep® technology is an advanced tool that enables high performance while meeting the power-saving requirements of mobile systems. Traditional Intel SpeedStep® technology shifts voltage and frequency from higher to lower levels and back in response to processor workload. Advanced Intel SpeedStep® Technology builds on this architecture using design strategies such as separation between voltage and frequency changes, clock partitioning and recovery.
Thermal monitoring technologies
Temperature monitoring technologies protect the processor package and system from thermal failures through various temperature management functions. An on-die Digital Thermal Sensor (DTS) detects core temperature, and thermal management features reduce package power consumption and possibly temperature to stay within normal operating limits.
Intel® Identity Protection Technology
Intel® Identity Protection Technology is a security token that provides a simple method of tamper protection for secure access to online customer and business data. Intel® Identity Protection Technology is a hardware device that uniquely identifies a PC for access to websites, financial institutions, and network services by proving that the login attempt is not being made by malware. Intel® Identity Protection Technology can be a critical component of two-factor authentication solutions to protect information when accessing websites and using company data to log in.
Intel® Deep Learning Boost (Intel® DL Boost)
A new set of integrated processor technologies designed to accelerate use cases in AI deep learning. Extends Intel AVX-512 with the addition of a new Vector Neural Network Instruction (VNNI) that significantly increases inference performance for deep learning compared to previous generations.
Intel® Thermal Velocity Boost
Intel® Thermal Velocity Boost (Intel® TVB) is a feature that opportunistically and automatically increases the clock frequency above the single-core and multi-core frequencies of Intel® Turbo Boost Technology 2.0 based on how much the processor is running below its maximum temperature and whether a Turbo energy budget is available. Frequency gain and duration depend on the workload, processor capabilities, and processor cooling solution.
