Intel® Processor Graphics refers to the technology that provides graphics, compute, media, and display capability for many of Intel’s processors, such as the 4th Generation Intel® Core™ Processor family of products. Within Intel, architects colloquially refer to Intel® Processor Graphics architecture as simply “Gen”, short for Generation. A specific generation of the Intel® Processor Graphics architecture may be referred to as “Gen6” for generation 6, or “Gen7” for generation 7, etc. The branded products Intel® HD Graphics 4600, Intel® Iris™ Graphics 5100, and Intel® Iris™ Pro Graphics 5200 are all derived from instances of Intel® Processor Graphics Gen7.5 architecture. Similarly Intel® HD Graphics 5300 derives from Intel® Processor Graphics Gen8.

This whitepaper details the Compute Architecture of Intel® Processor Graphics. It is foundational reading for developers that seek to optimize compute applications on Intel® Processor Graphics or engineers that seek to understand the mechanics and performance of Intel® Processor Graphics.
Intel® Processor Graphics Developer's Guide for 4th Generation Intel® Core™ Processor Graphics
This guide was created to assist developers in maximizing application performance on new Intel® graphics technologies, primarily focused on the new 4th generation Intel® microarchitecture (codenamed Haswell). The 2nd generation Intel microarchitecture (codenamed Sandy Bridge) was the first to have the graphics processor on the same die as the CPU. The graphics capabilities, generally referred to as “Intel® processor graphics,” has undergone numerous architectural changes that have significantly improved performance over previous generations. With the release of 4th generation Intel™ Core™ processors, developers have a new set of powerful graphics capabilities. This guide gives a high-level overview of the graphics hardware architecture and best practices for using DirectX* and OpenGL* on Intel processor graphics.
The latest Graphics Developer's Guide for 4th Generation Intel® Core™ Processor Graphics now includes OpenGL. Download the Intel Processor Graphics Developer's Guide for 4th Generation Intel® Core™ Processor Graphics. [PDF 1.17MB]
