Is there any good C/C++ tutorials or examples for learning Intel SSE and AVX instructions?
I found few on Microsoft MSDN and Intel sites, but it would be great to understand it from the basics..
For the visually inclined SIMD programmer, Stefano Tommesani's site is the best introduction to x86 SIMD programming.

The diagrams are only provided for MMX and SSE2, but once a learner gets proficient with SSE2, it is relatively easy to move on and read the formal specifications.
Intel IA-32 Instructions beginning with A to M
Intel IA-32 Instructions beginning with N to Z
In addition, it is important for Intel SIMD programmers to know the minimum required architecture for instructions that are outside the SSE2 generation.
