According to the chip maker, Larrabee will be a dramatic shift away from the shader processing designs used today by both major GPU vendors. It will feature a ďmany-core architectureĒ based on the original Pentium design with a new ring-bus-style interconnect for memory and coherent L2 cache across all cores. While Pentium processors are considered slow by todayís standards, Intel claims they become very fast and power efficient when you put a lot of them working in parallel on a single chip. And the fact that they support the current x86 instruction set reportedly makes Larrabee more flexible than a traditional graphics chip.
The company talked up other details of its forthcoming chipís architecture and shared some information about of the development tools that will be made available shortly. You can get the details here.
