With Intel® Virtualization Technology (VT-x), one hardware platform can be used as multiple "virtual" platforms. It provides improved manageability by reducing downtime and maintaining productivity by moving the compute operations into separate partitions.
Intel 64
In conjunction with the software, the Intel® 64 architecture enables 64-bit processing on servers, workstations, PCs, and mobile platforms.¹ Intel 64 improves performance by allowing the system to address more than 4 GB virtual and physical memory through this processor expansion.
Cache
The CPU cache is an area of fast memory located in the processor. Intel® smart cache refers to the architecture that allows all cores to dynamically share access to the load-level cache.
Intel® AES New Instructions
Intel® AES New Instructions (Intel® AES-NI) is a collection of instructions for fast and secure encryption and decryption of data. AES-NI are valuable components for cryptographic applications such as: Mass encryption/decryption applications, authentication, random number generation, and authentication encryption.
Retirement conditions
Standby states (C states) are used to save energy when the processor is idle. C0 is the operating state, i.e. the CPU performs useful tasks. C1 is the first idle state, C2 is the second state, etc., where more energy savings are applied for higher C-state numbers.
Intel® Turbo Boost Technology
Intel® Turbo Boost technology dynamically increases the frequency of a processor as needed by taking advantage of the temperature and power reserves to provide more speed and otherwise more energy efficiency when needed.

Execute Disable Bit is a hardware-based security feature that can reduce the risk of virus infections and prevent malicious software from running on the server or on the network.
Intel® Hyper-Threading Technology
Intel® Hyper-Threading Technology enables two processing threads per physical Kern. Applications with many threads can do more tasks in parallel and end tasks earlier.
Command set
A command set refers to the set of basic commands and instructions that a microprocessor understands and can execute. The value displayed indicates which Intel command 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), accelerates memory-intensive virtualization applications. Using extended page tables on platforms with Intel® virtualization technology reduces the total cost of storage and power, and increases battery life through hardware optimization of page table management.

The Intel SpeedStep® advanced technology is built on this architecture and uses design strategies such as voltage and frequency separation, clock partitioning and restoration.
Secure key
Intel® secure key is based on a digital random number generator that generates completely random numbers, thus strengthening encryption algorithms.
Intel speed shift technology
Intel® speed shift technology uses hardware-controlled P-states to achieve significantly faster response times with short-term, transient single-threaded workloads (as when browsing the web). For this, the processor is enabled to select the best operating frequency and voltage in each case, in order to achieve optimum performance and energy efficiency.
Intel® deep learning boost (Intel® DL boost)
A new set of embedded processor technologies to accelerate AI deep learning use cases. This adds a new VNNI (vector neural network instruction) to Intel AVX-512, which significantly improves deep learning performance over previous generations.
Command set extensions
Command set extensions are additional instructions for increasing 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
Intel® Turbo Boost Max Technology 3.0 identifies the core(s) with the best performance and delivers increased performance to these cores by increasing the clock frequency as needed, using power and temperature reserves.
Thermal monitoring technologies
Thermal monitoring technologies protect the processor package and the system from temperature-related failures through temperature management functions. A digital temperature sensor on the chip detects the temperature of the core, and the temperature management functions reduce the power consumption of the package and thus the temperature, as needed, in order to comply with the limits for normal operation.
Intel® volume management device (VMD)
Intel® volume management device (VMD) provides a common, robust hot-plug and LED management method for NVME solid-state drives.
Intel® Gauss and Neural Accelerators
