Intel is expected to unveil lots more information about Larrabee at SIGGRAPH this summer. A presentation about this GPU will be given on Tuesday, August 12.
Larrabee: A Many-Core x86 Architecture for Visual Computing
This paper introduces the Larrabee a many-core hardware architecture, a new software rendering pipeline, a many-core programming model, and performance analysis for several applications. Larrabee uses multiple in-order x86 CPU cores that are augmented by a wide vector processor unit, as well as fixed-function co-processors. This provides dramatically higher performance per watt and per unit of area than out-of-order CPUs on highly parallel workloads and greatly increases the flexibility and programmability of the architecture as compared to standard GPUs.
