Intel® AVX (Intel® Advanced Vector Extensions) is a 256 bit instruction set extension to SSE and is designed for applications that are floating point intensive. The enhancement in Intel® AVX allow for improved performance due to wider vectors, new extensible syntax, and rich functionality including the ability to better manage, rearrange and sort data.

Intel announced Intel® AVX in April 2008 to share the plans and start working with global developers prior to release of the microprocessor. Intel® AVX will be a part of the platforms ranging from notebooks to servers.
