Intel Virtualization Technology for Directed I/O (VT-d)Intel Virtualization Technology for Directed I/O (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 environments.Intel Virtualization Technology (VT-x)Intel Virtualization Technology (VT-x) allows one hardware platform to function as multiple virtual platforms. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions.Intel 64Intel 64 architecture delivers 64-bit computing on server. workstation. desktop and mobile platforms when combined with supporting software.1 Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.CacheCPU Cache is an area of fast memory located on the processor. Intel Smart Cache refers to the architecture that allows all cores to dynamically share access to the last level cache.Intel AES New InstructionsIntel AES New Instructions (Intel AES-NI) are a set of instructions that enable fast and secure data encryption and decryption. AES-NI are valuable for a wide range of cryptographic applications. for example: applications that perform bulk encryption/decryption. authentication. random number generation. and authenticated encryption.Idle StatesIdle States (C-states) are used to save power when the processor is idle. C0 is the operational state. meaning that the CPU is doing useful work. C1 is the first idle state. C2 the second. and so on. where more power saving actions are taken for numerically higher C-states.Intel Turbo Boost TechnologyIntel Turbo Boost Technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom to give you a burst of speed when you need it. and increased energy efficiency when you don t.Max Turbo FrequencyMax Turbo Frequency is the maximum single-core frequency at which the processor is capable of operating using Intel Turbo Boost Technology and. if present. Intel Turbo Boost Max Technology 3.0 and Intel Thermal Velocity Boost. Frequency is typically measured in gigahertz (GHz). or billion cycles per second.Execute Disable BitExecute 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.Intel Hyper-Threading TechnologyIntel Hyper-Threading Technology (Intel HT Technology) delivers two processing threads per physical core. Highly threaded applications can get more work done in parallel. completing tasks sooner.Instruction SetAn instruction set refers to the basic set of commands and instructions that a microprocessor understands and can carry out. The value shown represents which Intel s instruction set this processor is compatible with.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. Extended Page Tables in Intel Virtualization Technology platforms reduces the memory and power overhead costs and increases battery life through hardware optimization of page table management.Enhanced Intel SpeedStep TechnologyEnhanced Intel SpeedStep Technology is an advanced means of enabling high performance while 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. Enhanced Intel SpeedStep Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes. and Clock Partitioning and Recovery.Secure KeyIntel Secure Key consists of a digital random number generator that creates truly random numbers to strengthen encryption algorithms.Intel Speed Shift TechnologyIntel Speed Shift Technology uses hardware-controlled P-states to deliver dramatically quicker responsiveness with single-threaded. transient (short duration) workloads. such as web browsing. by allowing the processor to more quickly select its best operating frequency and voltage for optimal performance and power efficiency.Intel Deep Learning Boost (Intel DL Boost) on CPUA new set of embedded processor technologies designed to accelerate AI deep learning use cases. It extends Intel AVX-512 with a new Vector Neural Network Instruction (VNNI) that significantly increases deep learning inference performance over previous generations.Instruction Set ExtensionsInstruction Set Extensions are additional instructions which can increase performance when the same operations are performed on multiple d.
