Intel Graphics Technology (GT) is the collective name for a series of integrated graphics processors (IGPs) produced by Intel that are manufactured on the same package or die as the central processing unit (CPU). It was first introduced in 2010 as Intel HD Graphics.
Intel Iris Graphics and Intel Iris Pro Graphics are the IGP series introduced in 2013 with some models of Haswell processors as the high-performance versions of HD Graphics. Iris Pro Graphics was the first in the series to incorporate embedded DRAM.
In the fourth quarter of 2013, Intel integrated graphics represented, in units, 65% of all PC graphics processor shipments. However, this percentage does not represent actual adoption as a number of these shipped units end up in systems with discrete graphics cards.
Before the introduction of Intel HD Graphics, Intel integrated graphics were built into the motherboard's northbridge, as part of the Intel's Hub Architecture. They were known as Intel Extreme Graphics and Intel GMA. As part of the Platform Controller Hub (PCH) design, the northbridge was eliminated and graphics processing was moved to the same die as the central processing unit (CPU).
The previous Intel integrated graphics solution, Intel GMA, had a reputation of lacking performance and features, and therefore was not considered to be a good choice for more demanding graphics applications, such as 3D gaming. The performance increases brought by Intel's HD Graphics made the products competitive with integrated graphics adapters made by its rivals, Nvidia and ATI/AMD. Intel HD Graphics, featuring minimal power consumption that is important in laptops, was capable enough that PC manufacturers often stopped offering discrete graphics options in both low-end and high-end laptop lines, where reduced dimensions and low power consumption are important.
Intel HD and Iris Graphics are divided into generations, and within each generation are divided into 'tiers' of increasing performance, denominated by the 'GTx' label. Each generation corresponds to the implementation of a Gen graphics microarchitecture with a corresponding GEN instruction set architecture since Gen4.
In January 2010, Clarkdale and Arrandale processors with Ironlake graphics were released, and branded as Celeron, Pentium, or Core with HD Graphics. There was only one specification: 12 execution units, up to 43.2 GFLOPS at 900 MHz. It can decode a H264 1080p video at up to 40 fps.
Its direct predecessor, the GMA X4500, featured 10 EUs at 800 MHz, but it lacked some capabilities.

|HD Graphics||?||12||24||500||900||24.0 - 43.2|
In January 2011, the Sandy Bridge processors were released, introducing the "second generation" HD Graphics:
|Model number||Tier||Execution units||Boost Clock (MHz)||max GFLOPS (FP32)|
|HD Graphics 2000||1350||129.6|
|HD Graphics 3000||GT2||12||1350||259.2|
On 24 April 2012, Ivy Bridge was released, introducing the "third generation" of Intel's HD graphics:
|Model number||Tier||Execution units||Shading units||Boost Clock (MHz)||max GFLOPS|
|HD Graphics [Mobile]||GT1||6||48||1050||100.8|
|HD Graphics 2500||1150||110.4|
|HD Graphics 4000||GT2||16||128||1300||332.8|
For some low-power mobile CPUs there is limited video decoding support, while none of the desktop CPUs have this limitation.
On 12 September 2012, Haswell CPUs were announced, with four models of integrated GPUs:
|HD Graphics 4200||GT2||20||160||850||272|
|HD Graphics 4400||950 – 1150||304 – 368|
|HD Graphics 4600||900 – 1350||288 – 432|
|HD Graphics 5000||GT3||40||320||1000 – 1100||640 – 704|
|Iris Graphics 5100||1100 – 1200||704 – 768|
|Iris Pro Graphics 5200||GT3e||128||1300||832|
|Professional||HD Graphics P4600||GT2||20||160||N/A||1200 – 1250||384 – 400|
|HD Graphics P4700||1250 – 1300||400 – 416|
The 128 MB of eDRAM in the Iris Pro GT3e is in the same package as the CPU, but on a separate die manufactured in a different process. Intel refers to this as a Level 4 cache, available to both CPU and GPU, naming it Crystalwell. The Linux
drm/i915 driver is aware and capable of using this eDRAM since kernel version 3.12.
Integrated Iris Pro Graphics was adopted by Apple for their late-2013 15-inch MacBook Pro laptops (with Retina Display), which for a long time in the history of the series did not have discrete graphics cards, although only for the low-end model. It was also included on the late-2013 21.5-inch iMac.
In November 2013, it was announced that Broadwell-K desktop processors (aimed at enthusiasts) will also carry Iris Pro Graphics.

Intel Xe-HP and -HPG (DG2) is an in-development for gaming, enterprise and computing. Products expected to release products in 2021.
Intel Xe2 is a successor to Xe architecture.
Beginning with Sandy Bridge, the graphics processors include a form of digital copy protection and digital rights management (DRM) called Intel Insider, which allows decryption of protected media within the processor. Previously there was a similar technology called Protected Audio Video Path (PAVP).
Intel Graphics Technology supports the HDCP technology, but the actual HDCP support is depend on the computer's motherboard.
Intel Quick Sync Video is Intel's hardware video encoding and decoding technology, which is integrated into some of the Intel CPUs. The name "Quick Sync" refers to the use case of quickly transcoding ("syncing") a video from, for example, a DVD or Blu-ray Disc to a format appropriate to, for example, a smartphone. Quick Sync was introduced with the Gen 6 in Sandy Bridge microprocessors on 9 January 2011.
HD 2500 and HD 4000 GPUs in Ivy Bridge CPUs are advertised as supporting three active monitors, but this only works if two of the monitors are configured identically, which covers many but not all three-monitor configurations. The reason for this is that the chipsets only include two phase-locked loops (PLLs) for generating the pixel clocks timing the data being transferred to the displays.
Therefore, three simultaneously active monitors can only be achieved when at least two of them share the same pixel clock, such as:
Another possible three-monitor solution uses the Embedded DisplayPort on a mobile CPU (which does not use a chipset PLL at all) along with any two chipset outputs.

Support for Direct3D 9 in Mesa is only implemented for Gallium3D-style drivers, and is thus only available with the newer Gallium3D Iris driver, which is the default for Broadwell+ since Mesa 20.0. It is not supported in the classic Mesa i965 driver.
The classic Mesa i965 driver, which is the only one for Haswell and older on Linux, only supports core profile for OpenGL 3.1+, not compatibility profile. The Iris Gallium3D driver supports compatibility profile for OpenGL 4.6.
Intel developed a dedicated SIP core which implements multiple video decompression and compression algorithms branded Intel Quick Sync Video. Some are implemented completely, some only partially.

Intel releases programming manuals for most of Intel HD Graphics devices via its Open Source Technology Center. This allows various open source enthusiasts and hackers to contribute to driver development, and port drivers to various operating systems, without the need for reverse engineering.
Mesa, also called Mesa3D and The Mesa 3D Graphics Library, is an open source software implementation of OpenGL, Vulkan, and other graphics API specifications. Mesa translates these specifications to vendor-specific graphics hardware drivers.
A free and open-source graphics device driver is a software stack which controls computer-graphics hardware and supports graphics-rendering application programming interfaces (APIs) and is released under a free and open-source software license. Graphics device drivers are written for specific hardware to work within a specific operating system kernel and to support a range of APIs used by applications to access the graphics hardware. They may also control output to the display if the display driver is part of the graphics hardware. Most free and open-source graphics device drivers are developed by the Mesa project. The driver is made up of a compiler, a rendering API, and software which manages access to the graphics hardware.
The Intel Graphics Media Accelerator (GMA) is a series of integrated graphics processors introduced in 2004 by Intel, replacing the earlier Intel Extreme Graphics series and being succeeded by the Intel HD and Iris Graphics series.
Unified Video Decoder (UVD), previously called Universal Video Decoder, is the name given to AMD's dedicated video decoding ASIC. There are multiple versions implementing a multitude of video codecs, such as H.264 and VC-1.
AMD PowerPlay is the brand name for a set of technologies for the reduction of the energy consumption implemented in several of AMD's graphics processing units and APUs supported by their proprietary graphics device driver "Catalyst". AMD PowerPlay is also implemented into ATI/AMD chipsets which integrated graphics and into AMD's Imageon handheld chipset, that was sold to Qualcomm in 2008.
The Socket FS1 is for notebooks using AMD APU processors codenamed Llano, Trinity and Richland.
Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge. Intel officially announced CPUs based on this microarchitecture on June 4, 2013, at Computex Taipei 2013, while a working Haswell chip was demonstrated at the 2011 Intel Developer Forum. With Haswell, which uses a 22 nm process, Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "Y" suffix.
Intel Core are streamlined midrange consumer, workstation and enthusiast computers central processing units (CPU) marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time of their introduction, moving the Pentium to the entry level, and bumping the Celeron series of processors to the low end. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets.
Skylake is the codename used by Intel for a processor microarchitecture that was launched in August 2015 succeeding the Broadwell microarchitecture. Skylake is a microarchitecture redesign using the same 14 nm manufacturing process technology as its predecessor, serving as a "tock" in Intel's "tick–tock" manufacturing and design model. According to Intel, the redesign brings greater CPU and GPU performance and reduced power consumption. Skylake CPUs share their microarchitecture with Kaby Lake, Coffee Lake, Cannon Lake, Whiskey Lake, and Comet Lake CPUs.
Intel Quick Sync Video is Intel's brand for its dedicated video encoding and decoding hardware core. Quick Sync was introduced with the Sandy Bridge CPU microarchitecture on 9 January 2011 and has been found on the die of Intel CPUs ever since.
The Radeon HD 8000 series is a family of computer GPUs developed by AMD. AMD was initially rumored to release the family in the second quarter of 2013, with the cards manufactured on a 28 nm process and making use of the improved Graphics Core Next architecture. However the 8000 series turned out to be an OEM rebadge of the 7000 series.
Broadwell is the fifth generation of the Intel Core Processor. It's Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture. It is a "tick" in Intel's tick–tock principle as the next step in semiconductor fabrication. Like some of the previous tick-tock iterations, Broadwell did not completely replace the full range of CPUs from the previous microarchitecture (Haswell), as there were no low-end desktop CPUs based on Broadwell.
Silvermont is a microarchitecture for low-power Atom, Celeron and Pentium branded processors used in systems on a chip (SoCs) made by Intel. Silvermont forms the basis for a total of four SoC families:
Goldmont is a microarchitecture for low-power Atom, Celeron and Pentium branded processors used in systems on a chip (SoCs) made by Intel. They allow only one thread per core.
AMD PowerTune is a series of dynamic frequency scaling technologies built into some AMD GPUs and APUs that allow the clock speed of the processor to be dynamically changed by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw, heat generation and noise avoidance. AMD PowerTune aims to solve thermal design power and performance constraints.
Vulkan is a low-overhead, cross-platform 3D graphics and computing API. Vulkan targets high-performance realtime 3D graphics applications such as video games and interactive media across all platforms. Compared to OpenGL, Direct3D 11 and Metal, Vulkan is intended to offer higher performance and more balanced CPU/GPU usage. Other major differences from Direct3D 11 and OpenGL is Vulkan being a considerably lower-level API and offering parallel tasking. In addition to its lower CPU usage, Vulkan is designed to allow developers to better distribute work among multiple CPU cores.
Tiger Lake is Intel's codename for the 11th generation Intel Core mobile processors based on the new Willow Cove Core microarchitecture, manufactured using Intel's third-generation 10 nm process node known as 10SF. Tiger Lake replaces the Ice Lake family of mobile processors, representing an Optimization step in Intel's process–architecture–optimization model.
At Intel, architects colloquially refer to Intel processor graphics architecture as simply "Gen", shorthand for Generation.
The GEN instruction set is a general-purpose data-parallel instruction set optimized for graphics and media computations.
The GEN4 ISA describes the instructions supported by a GEN4 EU.
A limitation of this triple monitor support for Ivy Bridge is that two of the pipes need to share a PLL. Ivy Bridge has three planes, three pipes, three transcoders, and three FDI (Flexible Display Interface) interfaces for this triple monitor support, but there's only two pipe PLLs. This means that two of the three outputs need to have the same connection type and same timings. However, most people in a triple monitor environment will have at least two — if not all three — of the monitors be identical and configured the same, so this shouldn't be a terribly huge issue.
Despite the fact that Intel has been banging its drums about support for up to three displays on the upcoming 7-series motherboards in combination with a shiny new Ivy Bridge based CPU, this isn't likely to be the case. The simple reason behind this is that very few, if any motherboards will sport a pair of DisplayPort connectors.
The Intel® 7 Series Chipset based platform allows for the support of up to three concurrent displays with independent or replicated content. However, this comes with the requirement that either one of the displays is eDP running off the CPU or two DP interfaces are being used off the PCH. When configuring the 2 DP interfaces from the PCH, one may be an eDP if using Port D. This limitation exists because the 7 Series Intel PCH contains only two display PLLs (the CPU has one display PLL also) which will control the clocking for the respective displays. All display types other than DP have an external variable clock frequency associated with the display resolution that is being used. The DP interface has an embedded clocking scheme that is semi- variable, either at 162 or 270 MHz depending on the bandwidth required. Therefore, Intel only allows sharing of a display PLL with DP related interfaces.
This motherboard supports Triple Monitor. You may choose up to three display interfaces to connect monitors and use them simultaneously.
Connect up to three independent monitors at once using video outputs such as DisplayPort, Mini DisplayPort, HDMI, DVI, or VGA. Choose your outputs and set displays to either mirror mode or collage mode.
