At the game developer conference I presented a session "Hotspots, Flops, and uOps" that talked about optimizing code for Intel's latest SandyBridge processors. The session is now publicly available on gdcvault. The link is: http://www.gdcvault.com/play/1014645 The session dives deep into the processing and covers more than just AVX, since you need to ensure you are getting good throughput (instruction parallelism) in addition to SIMD (aka Vector) parallelism. stan melax
