Technical Product Specification
Separation between Voltage and Frequency changes. By stepping voltage up and

down in small increments separately from frequency changes, the processor is able to
reduce periods of system unavailability (which occur during frequency change). Thus,
the system is able to transition between voltage and frequency states more often,
providing improved power/performance balance.
Clock Partitioning and Recovery. The bus clock continues running during state

transition, even when the core clock and Phase-Locked Loop are stopped, which
allows logic to remain active. The core clock is also able to restart more quickly under

3.5.2.8 Intel ® Advanced Vector Extensions 2 (Intel
Intel ® Advanced Vector Extensions 2.0 (Intel
instruction set. Intel® AVX2 extends the Intel® Advanced Vector Extensions (Intel® AVX) with
256-bit integer instructions, floating-point fused multiply add (FMA) instructions and gather
operations. The 256-bit integer vectors benefit math, codec, image and digital signal
processing software. FMA improves performance in face detection, professional imaging, and
high performance computing. Gather operations increase vectorization opportunities for many
applications. In addition to the vector extensions, this generation of Intel processors adds new
bit manipulation instructions useful in compression, encryption, and general purpose
software.
3.5.2.9 Intel ® Node Manager 3.0
Intel ® Node Manager 3.0 enables the PTAS-CUPS (Power Thermal Aware Scheduling -
Compute Usage Per Second) feature of the Intel Server Platform Services 3.0 Intel ME
firmware. This is in essence a grouping of separate platform functionalities that provide
Power, Thermal, and Utilization data that together offer an accurate, real time characterization
of server workload. These functionalities include the following:
Computation of Volumetric Airflow

New synthesized Outlet Temperature sensor

CPU, memory, and I/O utilization data (CUPS)

This PTAS-CUPS data, can then be used in conjunction with the Intel
Intel ® Node Manager 3.0 power monitoring or controls and a remote management application
(such as the Intel ® Data Center Manager [Intel
loop data center management and monitoring system.
3.5.2.10 Intel Secure Key
®
The Intel ® 64 and IA-32 Architectures instruction RDRAND and its underlying Digital Random
Number Generator (DRNG) hardware implementation. Among other things, the Digital Random
Number Generator (DRNG) using the RDRAND instruction is useful for generating high-quality
keys for cryptographic protocols.
