Intel Processor Graphics Developer's Guide for 3rd Generation Intel® CoreTMProcessor Graphics on the Ivy Bridge microarchitecture
IntroductionThis guide was created to assist developers in maximizing application performance on new Intel® graphics technologies, primarily focused on the new Intel® microarchitecture codenamed Ivy Bridge. The document will introduce the new architecture and detail best practices with a focus on the DirectX 9, 10 and 11 APIs. Following the guidelines laid out in this document will help the developer’s game reach optimal performance on Intel processor graphics while providing a great gaming experience to the largest possible market. As reported by Mercury Research in the second quarter of 2011, Intel’s combined integrated graphics line currently enjoys the largest market share, standing at 50.4% for desktop parts, 59% for mobile parts.
With the introduction of the Intel microarchitecture codenamed Sandy Bridge, the graphics processor has moved onto the same die as the CPU, and is now referred to as “processor graphics”. In addition, processor graphics has enjoyed numerous architectural improvements that yield significant performance improvements over previous generations of Intel® integrated graphics parts.
The new generation of microarchitecture, codenamed Ivy Bridge, provides another jump in functionality and performance over Sandy Bridge microarchitecture. Ivy Bridge microarchitecture is manufactured on the new 22nm process technology, incorporating Intel’s new tri-gate (or 3D) transistor technology. This innovative new process yields greater performance at much lower power. For example, the new tri-gate transistors exhibit 36% faster switching speed than the equivalent transistors on the legacy process at the same voltage. Tri-gate transistors also leak about 10x less current in their off state, resulting in a power saving of approximately 50% when using a comparable performance profile.
