Cores communicate on a wide ring bus, which means fast access to memory and fixed function blocks; fast access for cache coherency. L2 cache is partitioned among the cores, which provides high aggregate bandwidth and allows data replication and sharing.

Intel's Larrabee processor is Intel's first multicore processor and first stand-alone graphics card. Larrabee is also a swipe at graphics chip makers Nvidia and Advanced Micro Devices, whose powerful graphics chips are starting to look like a threat to Silicon Valley's king of silicon chips. Intel Larrabee will have numerous x86 processor cores (Intel won't reveal how many processor cores) and support for OpenGL and DirectX, allowing it to run existing games and software requiring high-end graphics.
