Distributions may pick up components as they choose.

Intel Graphics Technology^[4] (GT)^[a] 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.^[5]

In the fourth quarter of 2013, Intel integrated graphics represented, in units, 65% of all PC graphics processor shipments.^[6] However, this percentage does not represent actual adoption as a number of these shipped units end up in systems outfitted with discrete graphics cards.

History[edit]

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.^[7] 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.

Generations[edit]

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.

Westmere[edit]

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:^[8] 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.^[9]

Sandy Bridge[edit]

In January 2011, the Sandy Bridge processors were released, introducing the 'second generation' HD Graphics:

Sandy Bridge Celeron and Pentium have Intel HD, while Core i3 and above have either HD 2000 or HD 3000. HD Graphics 2000 and 3000 include hardware video encoding and HD postprocessing effects.

Ivy Bridge[edit]

On 24 April 2012, Ivy Bridge was released, introducing the 'third generation' of Intel's HD graphics:^[10]

Graphics Media Accelerator Windows 10

Ivy Bridge Celeron and Pentium have Intel HD, while Core i3 and above have either HD 2500 or HD 4000. HD Graphics 2500 and 4000 include hardware video encoding and HD postprocessing effects.

For some low-power mobile CPUs there is limited video decoding support, while none of the desktop CPUs have this limitation.

Haswell[edit]

On 12 September 2012, Haswell CPUs were announced, with four models of integrated GPUs:

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.^[11][12][13]

Integrated Iris Pro Graphics was adopted by Apple for their late-2013 15-inch MacBook Pro laptops (with Retina Display), which for the first time in the history of the series did not have discrete graphics cards, although only for the low-end model.^[14] It was also included on the late-2013 21.5-inch iMac.^[15]

Broadwell[edit]

In November 2013, it was announced that Broadwell-K desktop processors (aimed at enthusiasts) will also carry Iris Pro Graphics.^[16]

The following models of integrated GPU are announced for Broadwell processors:^{[17][better source needed]}

Braswell[edit]

Skylake[edit]

The Skylake line of processors, launched in August 2015, retires VGA support, while supporting multi-monitor setups of up to three monitors connected via HDMI 1.4, DisplayPort 1.2 or Embedded DisplayPort (eDP) 1.3 interfaces.^[18][19]

The following models of integrated GPU are available or announced for the Skylake processors:^{[20][21][better source needed]}

Apollo Lake[edit]

Kaby Lake[edit]

New Features: Speed increases, support for 4K UHD 'premium' (DRM encoded) streaming services, media engine with full hardware acceleration of 8- and 10-bit HEVC and VP9 decode^[23][24]

Kaby Lake Refresh / Amber Lake / Coffee Lake / Whiskey Lake / Comet Lake[edit]

New Features: HDCP 2.2 support ^[25]

Gemini Lake[edit]

New Features: HDMI 2.0 support, VP9 10-bit Profile2 hardware decoder^[27]

Ice Lake[edit]

New Features: 10 nm Gen 11 GPU microarchitecture, two HEVC 10-bit encode pipelines, three 4K display pipelines (or 2x 5K60, 1x 4K120), variable rate shading (VRS) ^[28]

Features[edit]

Intel Insider[edit]

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.^[29][30] Previously there was a similar technology called Protected Audio Video Path (PAVP).

Intel Quick Sync Video[edit]

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.

Graphics Virtualization Technology[edit]

Graphics Virtualization Technology was announced 1 January 2014 and is supported by Iris Pro GPUs.^[31]

Multiple monitors[edit]

Ivy Bridge[edit]

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^[32] 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.^[33]

Therefore, three simultaneously active monitors can only be achieved when at least two of them share the same pixel clock, such as:

• Using two or three DisplayPort connections, as they require only a single pixel clock for all connections.^[34] Passive adapters from DisplayPort to some other connector do not count as a DisplayPort connection, as they rely on the chipset being able to emit a non-DisplayPort signal through the DisplayPort connector. Active adapters that contain additional logic to convert the DisplayPort signal to some other format count as a DisplayPort connection.
• Using two non-DisplayPort connections of the same connection type (for example, two HDMI connections) and the same clock frequency (like when connected to two identical monitors at the same resolution), so that a single unique pixel clock can be shared between both connections.^[32]

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.^[34]

Haswell[edit]

ASRock Z87- and H87-based motherboards support three displays simultaneously.^[35]Asus H87-based motherboards are also advertised to support three independent monitors at once.^[36]

Capabilities[edit]

OpenCL 2.1 and 2.2 possible with software update on OpenCL 2.0 hardware (Broadwell+) with future software updates.^[70]

Intel Gma 3150 Windows 10

While Mesa does support Direct3D 9.3, this is only implemented for Gallium3D-style drivers and not for the Mesa Intel driver.

Capabilities (GPU video acceleration)[edit]

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.

Hardware-accelerated algorithms[edit]

Intel Pentium and Celeron family[edit]

Intel Atom family[edit]

Documentation[edit]

Intel releases programming manuals for most of Intel HD Graphics devices via its Open Source Technology Center.^[83] 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.

32. ^ ^abMichael Larabel (2011-10-06). 'Details On Intel Ivy Bridge Triple Monitor Support'. Phoronix. 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.
33. ^LG Nilsson (2012-03-12). 'Most desktop Ivy Bridge systems won't support three displays'. VRZone. 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.
34. ^ ^abDavid Galus (February 2013). 'Migration to New Display Technologies on Intel Embedded Platforms'(PDF). Intel. 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.
