Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors (Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors, from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model. The name is also applied more broadly to the Xeon and Core i7 Ivy Bridge-E series of processors released in 2013.

Ivy Bridge processors are backward compatible with the Sandy Bridge platform, but such systems might require a firmware update (vendor specific).[2] In 2011, Intel released the 7-series Panther Point chipsets with integrated USB 3.0 and SATA 3.0 to complement Ivy Bridge.[3]

Volume production of Ivy Bridge chips began in the third quarter of 2011.[4] Quad-core and dual-core-mobile models launched on April 29, 2012 and May 31, 2012 respectively.[5] Core i3 desktop processors, as well as the first 22 nm Pentium, were announced and available the first week of September 2012.[6]

Ivy Bridge is the last Intel platform on which Windows prior to Windows 7 (up to NT 6.0, X86 & X64) will be officially supported by Microsoft. It is also the earliest Intel microarchitecture to officially support Windows 10 64-bit (NT 10.0).[7]

Overview

The Ivy Bridge CPU microarchitecture is a shrink from Sandy Bridge and remains largely unchanged. Like its predecessor, Sandy Bridge, Ivy Bridge was also primarily developed by Intel's Israel branch, located in Haifa, Israel.[8] Notable improvements include:[9][10]

New 22 nm Tri-gate transistor ("3-D") technology offer as much as a 50% reduction to power consumption at the same performance level as compared to 2-D planar transistors on Intel's 32 nm process.[11]
A new pseudorandom number generator and the RDRAND instruction,[12] codenamed Bull Mountain.[13]

Ivy Bridge features and performance

The mobile and desktop Ivy Bridge chips also include some minor yet notable changes over Sandy Bridge:

CPU

F16C (16-bit floating-point conversion instructions)[14]
RDRAND instruction (Intel Secure Key)[15]
Max CPU multiplier of 63 (versus 57 for Sandy Bridge)[16]
Configurable TDP (cTDP) for mobile processors[17]
A 14- to 19-stage instruction pipeline, depending on the micro-operation cache hit or miss[18]

Translation lookaside buffer sizes[19][20]

Name	Level	4 KB	2 MB	1 GB
DTLB	1st	64	32	4
ITLB	1st	128	8 / logical core	none
STLB	2nd	512	none	none

GPU

The built-in GPU has 6 or 16 execution units (EUs), compared to Sandy Bridge's 6 or 12.[21]
Intel HD Graphics with DirectX 11, OpenGL 4.0, and OpenCL 1.2 support on Windows.[22] On Linux, OpenGL 4.2 is supported since Mesa 17.1.[23]
Support for up to three displays (with some limitations: with chipset of 7-series and using two of them with DisplayPort or eDP)[24]
Multiple 4K displays video playback
Intel Quick Sync Video version 2[21]

IO

RAM support up to 2800 MT/s in 200 MHz increments[16]
DDR3L for mobile CPUs
PCI Express 3.0 support (omitted on Core i3, Pentium, and ultra-low-voltage [ULV] processors)[25]

Benchmark comparisons

Compared to its predecessor, Sandy Bridge:

3% to 6% increase in CPU performance when compared clock for clock[26][27]
25% to 68% increase in integrated GPU performance[28]

Thermal performance issues

Ivy Bridge's temperatures are reportedly 10 °C higher compared to Sandy Bridge when a CPU is overclocked, even at default voltage setting.[29] Impress PC Watch, a Japanese website, performed experiments that confirmed earlier speculations that this is because Intel used a poor quality (and perhaps lower cost) thermal interface material (thermal paste, or "TIM") between the chip and the heat spreader, instead of the fluxless solder of previous generations.[30][31][32] The mobile Ivy Bridge processors are not affected by this issue because they do not use a heat spreader between the chip and cooling system. Socket 2011 Ivy Bridge processors continue to use the solder.[33]

Enthusiast reports describe the TIM used by Intel as low-quality,[32] and not up to par for a "premium" CPU, with some speculation that this is by design to encourage sales of prior processors.[30] Further analyses caution that the processor can be damaged or void its warranty if home users attempt to remedy the matter.[30][34] The TIM has much lower thermal conductivity, causing heat to trap on the die.[29] Experiments with replacing this TIM with a higher-quality one or other heat removal methods showed a substantial temperature drop, and improvements to the increased voltages and overclocking sustainable by Ivy Bridge chips.[30][35]

Intel claims that the smaller die of Ivy Bridge and the related increase in thermal density is expected to result in higher temperatures when the CPU is overclocked; Intel also stated that this is as expected and will likely not improve in future revisions.[36]

Models and steppings

All Ivy Bridge processors with one, two, or four cores report the same CPUID model 0x000306A9, and are built in four different configurations differing in the number of cores, L3 cache and GPU execution units.

Die code name	CPUID	Stepping	Die size	Die dimensions	Transistors	Cores	GPU EUs	L3 cache	Sockets

Ivy Bridge–based Xeon processors

Intel Ivy Bridge–based Xeon microprocessors (also known as Ivy Bridge-E) is the follow-up to Sandy Bridge-E, using the same CPU core as the Ivy Bridge processor, but in LGA 2011, LGA 1356 and LGA 2011-1 packages for workstations and servers.

Additional high-end server processors based on the Ivy Bridge architecture, code named Ivytown, were announced September 10, 2013 at the Intel Developer Forum, after the usual one year interval between consumer and server product releases.[41][42][43]

The Ivy Bridge-EP processor line announced in September 2013 has up to 12 cores and 30 MB third level cache, with rumors of Ivy Bridge-EX up to 15 cores and an increased third level cache of up to 37.5 MB,[44][45] although an early leaked lineup of Ivy Bridge-E included processors with a maximum of 6 cores.[46]

Both Core-i7 and Xeon versions are produced: the Xeon versions marketed as Xeon E5-1400 V2 act as drop-in replacements for the existing Sandy Bridge-EN based Xeon E5, Xeon E5-2600 V2 versions act as drop-in replacements for the existing Sandy Bridge-EP based Xeon E5, while Core-i7 versions designated i7-4820K, i7-4930K and i7-4960X were released on September 10, 2013, remaining compatible with the X79 and LGA 2011 hardware.[45][47]

For the intermediate LGA 1356 socket, Intel launched the Xeon E5-2400 V2 (codenamed Ivy Bridge-EN) series in January 2014.[48] These have up to 10 cores.[49]

A new Ivy Bridge-EX line marketed as Xeon E7 V2 had no corresponding predecessor using the Sandy Bridge microarchitecture but instead followed the older Westmere-EX processors.

Roadmap

Intel demonstrated the Haswell architecture in September 2011, which began release in 2013 as the successor to Sandy Bridge and Ivy Bridge.[55]

Fixes

Microsoft has released a microcode update for selected Sandy Bridge and Ivy Bridge CPUs for Windows 7 and up that addresses stability issues. The update, however, negatively impacts Intel G3258 and 4010U CPU models.[56][57][58]

Notes

Transistor counts for M-2, H-2 and HM-4 were determined by a comparison of transistor counts in Sandy Bridge and HE-4. Performing a comparative analysis gave counts of 108 million transistors per core, 67 million transistors per 1 MB of L3 cache, 88 million transistors for the memory controller and other chip features, and roughly 21 million transistors for each execution unit inside the Intel HD 4000. All this is an attempt to determine the transistor count mathematically, and is not backed by any sources. Thus, these transistor counts may be inaccurate.
