Separate scalar and vector units with separate registers; in-order x86 scalar core; vector unit: 16 32-bit ops/clock; short execution pipelines; fast access from L1 cache; direct connection to each core's subset of the L2 cache; prefetch instructions load L1 and L2 caches.

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.
