Ivy Bridge

Ivy Bridge is the name used for a
“third generation” line of processors utilizing the base of 22 nm
manufacturing process introduced by Intel. The name is likewise connected all
the more extensively to the 22 nm die shrink of the Sandy Bridge
microarchitecture in view of FinFET (“3D”) Tri-Gate transistors, which
is additionally utilized as a part of the Xeon and Core i7 Ivy Bridge-EX
(Ivytown), Ivy Bridge-EP and Ivy Bridge-E microchips introduced in 2013. It is
important to note that Ivy Bridge processors are backward compatible with the
Sandy Bridge platform, yet such systems may require updating the firmware
(which is vendor specific). In 2011, Intel introduced its 7-series Panther
Point chipsets with combined USB 3.0 to supplement Ivy Bridge. Volume creation
of Ivy Bridge chips started in the third quarter of the year 2011. The Quad-core
model was launched on 29 April 2012 whereas the dual-core-mobile model was
introduced 31 May 2012. Core i3 desktop processors, along with the first 22 nm
Pentium, were announced and available to consumers in the first week of
September, 2012. It is the last Intel microarchitecture for which Windows XP
driver bolster authoritatively exists.

The Benchmark comparisons between Ivy
and Sandy Bridges will be drawn. Contrasted with its forerunner, Sandy Bridge,
the Ivy Bridge offers:

1.      3% to 6% expansion in CPU execution
when it’s compared clock for clock

2.      25% to 68% addition in the integrated
GPU performance

An overview of this introduction will
now be discussed. The Ivy Bridge CPU microarchitecture is the successor of
Sandy Bridge and it remains unaltered to a great extent. Like its forerunner,
Sandy Bridge, Ivy Bridge was additionally essentially created by Intel’s Israel
branch, situated in Haifa, Israel. Remarkable enhancements include:-

1.      22 nm Tri-gate transistor
(“3-D”) technology (up to half less power utilization at a similar
execution level as 2-D planar transistors)

2.      An arbitrary number generator and the
RdRand direction, which is codenamed as “Bull Mountain”.

We also have to discuss the features
of these Bridges. The mobile and desktop Ivy Bridge chips likewise incorporate
noteworthy changes over Sandy Bridge:-

1.      16 
bit floating point conversion instructions known as F16C

2.      RdRand instruction that is the Intel
Secure Key

3.      PCI Express 3.0 support that is not
compatible with Core i3 and ULV processors

4.      Sandy Bridges use a maximum of 57 CPU
multipliers but Ivy Bridges use 63

5.      It supports a RAM of 2800 MT per
seconds in 200 MHz additions

6.      Sandy Bridges have six or twelve
execution units (EUs) built in GPU’s whereas Ivy Bridges have six or sixteen

7.      It has a multiple amount of 4K video

8.      For mobile processors, DDR3L and
configurable TDP which is the “cTDP”

9.      Intel Quick Synchronization Video
utilizing version 2

10.  It supports up to three displays but
it offers some limitations. That is, it has a chipset of 7 series, utilizing
two of them with DisplayPort or eDP.

11.  An instruction pipeline of stage 14 to
19 but this depends on the micro operation cache hit or cache miss.

12.  It utilizes Intel HD Graphics with
DirectX 11, OpenGL 3.1 along with a support for OpenCL 1.1. The WHQL (drivers) and its successor
drivers support OpenGL 4.0. Another important feature is that Mesa 17.1
supports OpenGL 4.2 on Linux.
