4th gen Intel® Core™ processor features at a glance
Features
Benefits
LINS
A set of new instructions that works in conjunction with AVX 2.0 instructions to accelerate CPU
performance during certain operations that include high-definition content decoding, encryption during
compression/decompression, and cryptographic security protocols.
TSX-NI
TSX-NI is a set of new instructions focused on enterprise-level multi-threaded performance scaling, mak-
ing parallel operations more efficient via improved control of software threads and locks. This offers
performance benefits for enterprise-level big data analytics/business intelligence and visualization apps,
which involve multi-user collaboration.
Intel® Advanced Vector Extensions (Intel® AVX)
2.0
AVX 2.0 is an extension of AVX 1.0 with new optimized instructions to deliver enhanced performance
on floating point–intensive apps. AVX 2.0 adds 256bit integer instructions and new instructions for
FMA (Fused Multiply Add). FMA delivers better performance on media and floating point computations,
including face recognition; professional imaging; high-performance computing; consumer video and
imaging; compression; and encryption.
Collaborative Processor Performance Control
(CPPC)
A new technology based on the ACPI 5.0 specification that dynamically modulates performance vs. active
application power. It reduces active power to deliver better battery life and allows deeper lower power
states to be reached (compared to prior generations of Intel Core processor products).
Intel® BIOS Guard (Codename Platform Flash
Armoring Technology [PFAT])
Platform Flash Armoring Technology is an augmentation of existing chipset-based BIOS flash protection
capabilities targeted to address the increasing malware threat to BIOS flash storage. It protects the BIOS
flash from modification without platform manufacturer authorization, helps defend the platform against
low-level DOS (denial of service) attacks, and restores BIOS to a known good state after an attack.
Intel® Boot Guard
Hardware-based boot integrity protection that prevents unauthorized software and malware takeover
of boot blocks critical to a system’s function, thus providing added level of platform security based on
hardware. Configurable boot types include:
Measured Boot
—
Measures the initial boot block into the platform storage device such as trusted
platform module (TPM) or Intel® Platform Trust Technology (PTT).
Verified Boot
—
Cryptographically verifies the platform initial boot block using the boot policy key.
Intel® OS Guard (Formerly Supervisor Mode
Execution Protections [SMEP])
An enhanced hardware-based security feature that protects the OS (operating system) kernel. OS Guard
protects areas of memory marked as user mode pages and prevents attack code, which is in a user mode
page or a code page, to take over the OS kernel. OS Guard is not application-specific and protects the
kernel from any application.
Intel® Platform Trust Technology
A trusted element of the platform execution that provides enhanced security by verifying the boot
portion of the boot sequence.
VMCS shadowing
VMCS shadowing allows a Virtual Machine Manager (VMM) running in a guest (nested virtualization) to
access a shadow VMCS memory area using the normal VMRead/VMWrite instructions. This new technology
reduces overhead for a more natural and responsive user experience. It also allows users to take control of
their personal and professional data and apps while being protected by game-changing security.
Intel® Active Management Technology
(Intel® AMT)
2
Using built-in platform capabilities and popular third-party management and security applications, Intel
AMT allows IT to better discover, heal, and protect networked computing assets.
Intel® Small Business Advantage (Intel® SBA)
14
Helps small businesses enhance the security and productivity of their small business with a range of out
of the box features, including software monitor, data backup and restore, USB port blocker, health center,
and wireless display.
Intel® Rapid Storage Technology
With additional hard drives added, provides quicker access to digital photo, video, and data files with RAID
0, 5, and 10, and greater data protection against a hard disk drive failure with RAID 1, 5, and 10.
21
Dynamic Storage Accelerator unleashes the maximum performance of Solid State Drives (SSD)
when multitasking.
21
Intel® Smart Response Technology
8
Spend less time waiting, with faster access to the files and applications you use the most.
Intel® Smart Connect Technology
13
Stay current with automatic, no-wait updates to your email and social networks, even when your device
is asleep. Combine with Intel® WiFi HotSpot Assistant
26
to automatically connect to free and paid WiFi
hotspots and refresh content in more locations worldwide.
