Quoting - Igor Levicki

You can do one of the following:

1. Use Intel compiler which supports AVX code generation and generate two code paths by using proper switches.
2. Write two versions of the performance critical function, one for SSE4.2, one for AVX.

You cannot write assembler code which uses AVX, and make it run on Core i7 (except in AVX emulator which is not optimal).


Thank you very much Igor Levicki.
