Popis
Intel® Optane™ Memory Supported
Intel® Optane™ memory is a revolutionary new class of non-volatile memory
that sits in between system memory and storage to accelerate system performance
and responsiveness. When combined with the Intel® Rapid Storage Technology
Driver, it seamlessly manages multiple tiers of storage while presenting one
virtual drive to the OS, ensuring that data frequently used resides on the
fastest tier of storage. Intel® Optane™ memory requires specific hardware and
software configuration.
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 don’t.
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® 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® 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.
Intel® 64
Intel® 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.
Instruction Set
An 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.
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).
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 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.
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.
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 thereby temperature
when required in order to remain within normal operating limits.
Intel® Identity Protection Technology
Intel® Identity Protection Technology is a built-in security token technology
that helps provide a simple, tamper-resistant method for protecting access to
your online customer and business data from threats and fraud. Intel® IPT
provides a hardware-based proof of a unique user’s PC to websites, financial
institutions, and network services; providing verification that it is not
malware attempting to login. Intel® IPT can be a key component in two-factor
authentication solutions to protect your information at websites and business
log-ins.
