Intel HD Graphics is a series of integrated graphics processors (IGPs) introduced by Intel in 2010 that are manufactured on the same package or die as the central processing unit (CPU).
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 outfitted 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 their low-end and mid-range laptop lines.
