Intel Graphics Technology[4] (GT){{Efn|name="intel-gt-abbreviation"|The abbreviation "GT" appears in certain monitoring tools, such as Intel Power Gadget in reference to the graphics core on Intel processors.}} 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

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

{{See also|List of Intel graphics processing units}}

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

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]

HD Graphics ? 12 900 43.2

Sandy Bridge

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
HD Graphics GT16 1000 96
HD Graphics 2000 1350 129.6
HD Graphics 3000 GT2 12 1350 259.2

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

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

Model number Tier Execution unitsShading units Boost Clock (MHz) max GFLOPS
HD Graphics GT1648 1050 100.8
HD Graphics 2500 1150 110.4
HD Graphics 4000 GT2 16128 1300 332.8

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.

{{Anchor|IRIS-PRO|CRYSTALWELL}}Haswell

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

Market Model number Tier Execution unitsShading units eDRAM (MB) Boost Clock (MHz) max GFLOPS
Consumer HD Graphics GT1 1080N/A 1150 184
HD Graphics 4200 GT220160 850 272

Server HD Graphics P4600 GT220160N/A 1200–1250 384–400
HD Graphics P4700 1250–1300 400–416

The 128 MB of eDRAM in the Iris Pro GT3e is on the same package as the CPU, but in 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. Linux support for this eDRAM is expected in kernel version 3.12, by making the drm/i915 driver aware and capable of using it.[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

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|date=May 2015}}

Features

{{Anchor|INTEL-INSIDER}}Intel Insider

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.[38][39] Previously there was a similar technology called Protected Audio Video Path (PAVP).

Intel Quick Sync Video

{{Main article|Intel Quick Sync Video}}

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

{{Main article|Graphics Virtualization Technology}}Graphics Virtualization Technology was announced {{date|2014-01-01}} and is supported by Iris Pro GPUs.[40]

Multiple monitors

{{See also|Multi-monitor|Digital Visual Interface#Clock and data relationship}}

Ivy Bridge

HD 2500 and HD 4000 GPUs in Ivy Bridge CPUs are advertised as supporting three active monitors, but many users have found that this does not work for them due to the chipsets only supporting two active monitors in many common configurations. The reason for this is that the chipsets only include two phase-locked loops (PLLs); a PLL generates a pixel clock at a certain frequency which is used to sync the timings of data being transferred between the GPU and displays.[41]

Therefore, three simultaneously active monitors can only be achieved by a hardware configuration that requires only two unique pixel clocks, such as:

  • Using two or three DisplayPort connections, as they require only a single pixel clock for all connections.[42] Passive adapters from DisplayPort to some other connector rely on the chipset being able to emit a non-DisplayPort signal through the DisplayPort connector, and thus do not count as a DisplayPort connection. Active adapters that contain additional logic to convert the DisplayPort signal to some other format count as a DisplayPort connection.
  • By 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.[43]
  • Using the Embedded DisplayPort on a mobile CPU along with any two other outputs.[42]

Haswell

ASRock Z87- and H87-based motherboards support three displays simultaneously.[44] Asus H87-based motherboards are also advertised to support three independent monitors at once.[45]

The simple reason behind this is that very few, if any motherboards will sport a pair of DisplayPort connectors.}}

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.}}

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.}}
