Intel announced on Monday about their forthcoming Larrabee architecture which is going to be the foundation for their future Intel “many-core” graphics processors. This will be a major shift from their Pentium Pro based architecture model. They will present the model at the upcomg SIGGRAPH 2008 conference.
Basically, Larrabee is about using many simple x86 cores– more than you’d see in the central processor (CPU) of the system– to implement a graphics processor (GPU). Further, Intel also expects Larrabee to serve as the technological catalyst responsible for jump-starting “an industry-wide effort to create and optimize software for the dozens, hundreds and thousands of cores expected to power future computers.”
Larrabee is a tera-scale research program which is the largest technological investment from Intel. Intel spent US$1.47 billion on research and development during the second quarter — more than the $1.35 billion that rival Advanced Micro Devices recorded in revenue for the same period.
Working directly with some of the world’s top 3D graphics experts, Larrabee will give developers of games and APIs (Application Programming Interface) a blank canvas onto which they can innovate like never before,” said Intel in an official release.
The Larrabee cores are based on the design of the Pentium processor cores, with enhancements such as a wide vector processing unit, 64-bit extensions, multithreading, and pre-fetching, Intel said. The chip is going to have a dedicated co-processors to handle specific graphics functions, such as textures. The GPUs are capable of parallel computing and improves application and graphics performance.
