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:^[13] 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.^[14]

Sandy Bridge

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

On 24 April 2012, Ivy Bridge was released, introducing the "third generation" of Intel's HD graphics:^[15]

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. HD P4000 is featured on the Ivy Bridge E3 Xeon processors with the 12X5 v2 descriptor, and supports unbuffered ECC RAM.

Haswell

In June 2013, Haswell CPUs were announced, with four tiers 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.^[16][17][18]

Broadwell

In November 2013, it was announced that Broadwell-K desktop processors (aimed at enthusiasts) would also carry Iris Pro Graphics.^[19]

The following models of integrated GPU are announced for Broadwell processors:^{[20][better source needed]}

Braswell

Skylake

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.^[21][22]

The following models of integrated GPU are available or announced for the Skylake processors:^{[23][24][better source needed]}

Apollo Lake

The Apollo Lake line of processors was launched in August 2016.

Kaby Lake

The Kaby Lake line of processors was introduced in August 2016. 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.^[26][27]

Kaby Lake Refresh / Amber Lake / Coffee Lake / Coffee Lake Refresh / Whiskey Lake / Comet Lake

The Kaby Lake Refresh line of processors was introduced in October 2017. New features: HDCP 2.2 support^[28]

Gemini Lake/Gemini Lake Refresh

New features: HDMI 2.0 support, VP9 10-bit Profile2 hardware decoder^[30]

Ice Lake

New features: 10 nm Gen 11 GPU microarchitecture, two HEVC 10-bit encode pipelines, three 4K display pipelines (or 2× 5K60, 1× 4K120), variable rate shading (VRS),^[31][32][33] and integer scaling.^[34]

While the microarchitecture continues to support double-precision floating-point as previous versions did, the mobile configurations of it do not include the feature and therefore on these it is supported only through emulation.^[35]

Ivy Bridge

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^[57] 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.^[58]

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.^[59] 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.^[57]

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.^[59]

Haswell

ASRock Z87- and H87-based motherboards support three displays simultaneously.^[60] Asus H87-based motherboards are also advertised to support three independent monitors at once.^[61]
