single threaded workloads. It should be enabled in the BIOS for the processor to operate with 
maximum performance. 
3.2.8  Enhanced Intel SpeedStep® Technology 
The processor supports Enhanced Intel SpeedStep® Technology (EIST) as an advanced means 
of enabling very high performance while also meeting the power conservation needs of the 
platform. 
Enhanced Intel SpeedStep® Technology builds upon that architecture using design strategies 
that include the following: 
  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 
Enhanced Intel SpeedStep® Technology. 
3.2.9  Intel® Advanced Vector Extensions 2 (Intel® AVX2) 
Intel® Advanced Vector Extensions 2.0 (Intel® AVX2) is the latest expansion of the 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. 
3.2.10  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 FW. 
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)
