The document will introduce the new architecture and detail best practices with a focus on DirectX 9, 10 and 11 APIs. Following the guidelines set forth in this document, the developer game will achieve optimum performance in Intel processor graphics while providing great gaming experience to the largest market possible.
As reported by Mercury Research in the second quarter of 2011, Intel's integrated integrated graphics line currently enjoys the largest market share, standing at 50.4% for desktops, 59% for parties mobile phones. With the introduction of the Intel microarchitecture code name Sandy Bridge, the graphics processor has moved in the same given the CPU, and is now known as "processor graphics."
In addition, processor graphics have enjoyed numerous architectural improvements that yield significant performance improvements over previous generations of integrated Intel® graphics. The new generation of microarchitecture, codenamed Ivy Bridge, provides another leap in functionality and performance over the Sandy Bridge microarchitecture.
The Ivy Bridge microarchitecture is built on the new 22nm process technology, incorporating Intel's new tri-gate (or 3D) transistor technology. This new innovative process produces a higher performance at much lower power. For example, the new tri-gate transistors exhibit a switching speed 36% faster than equivalent transistors in the inherited process at the same voltage. Three-door transistors also have a 10-fold lower current in their off state, resulting in an energy savings of approximately 50% when using a comparable performance profile.
