Larrabee differs significantly from AMD’s Radeon and NVIDIA’s GeForce processors. For starters, Larrabee is based on the x86 instruction set found in CPU architecture. Intel vice president Steve Smith emphasized that Larrabee is not just a GPU, but a multi-core die capable of any stream processing task.
Intel’s hybrid CPU and GPU chips are set to be released in two flavors, both of which will be based on the Nehalem CPU architecture. The first version, dubbed Havendale, will be a desktop chip, while the second version, dubbed Auburndale, will be a notebook chip.
Intel has been very friendly with the open source community while creating drivers and releasing documentation for their chipsets at the Intel Linux Graphics Driver site; my hope is that this will continue with future hardware architectures.
