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. It enables an environment where applications can run within their own space, protected from all other software on the system.

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 64
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.

CPU 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 Instructions
Intel 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.

Intel Turbo Boost Technology
Intel 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 dont.

Max Turbo Frequency
Max 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 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.

Intel Hyper-Threading Technology
Intel 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.

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. 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 Technology
Enhanced 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.

Intel Speed Shift Technology
Intel 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 Turbo Boost Technology 2.0 Frequency
Intel Turbo Boost Technology 2.0 Frequency is the maximum single core frequency at which the processor is capable of operating using Intel Turbo Boost Technology. Frequency is typically measured in gigahertz (GHz), or billion cycles per second.

Intel Software Guard Extensions (Intel SGX)
Intel Software Guard Extensions (Intel SGX) provide applications the ability to create hardware enforced trusted execution protection for their applications sensitive routines and data. Intel SGX provides developers a way to partition their code and data into CPU hardened trusted execution environments (TEEs).

Intel Deep Learning Boost (Intel DL Boost)
A 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 Extensions
Instruction Set Extensions are additional instructions which 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).

Intel Turbo Boost Max Technology 3.0 Frequency
Intel Turbo Boost Max Technology 3.0 identifies the best performing core(s) on a processor and provides increased performance on those cores through increasing frequency as needed by taking advantage of power and thermal headroom. Intel Turbo Boost Max Technology 3.0 frequency is the clock frequency of the CPU when running in this mode.

Intel Turbo Boost Max Technology 3.0
Intel Turbo Boost Max Technology 3.0 identifies the best performing core(s) on a processor and provides increased performance on those cores through increasing frequency as needed by taking advantage of power and thermal headroom.

Intel Total Memory Encryption
TME Total Memory Encryption (TME) helps protect data against exposure via physical attack on memory, such as cold-boot attacks.

Max # of UPI Links
Intel Ultra Path Interconnect (UPI) links are a high speed, point-to-point interconnect bus between the processors, delivering increased bandwidth and performance over Intel QPI.

# of AVX-512 FMA Units
Intel Advanced Vector Extensions 512 (AVX-512), new instruction set extensions, delivering ultra-wide (512-bit) vector operations capabilities, with up to 2 FMAs (Fused Multiply Add instructions), to accelerate performance for your most demanding computational tasks.

Intel Resource Director Technology (Intel RDT)
Intel RDT brings new levels of visibility and control over how shared resources such as last-level cache (LLC) and memory bandwidth are used by applications, virtual machines (VMs) and containers.

Intel Optane Persistent Memory Supported
Intel Optane persistent memory is a revolutionary tier of non-volatile memory that sits between memory and storage to provide large, affordable memory capacity that is comparable to DRAM performance.Delivering large system-level memory capacity when combined with traditional DRAM, Intel Optane persistent memory is helping transform critical memory constrained workloads from cloud, databases, in-memory analytics, virtualization, and content delivery networks.
