The first AVX hardware (early 2011) runs the JE avx binary, but only a bit faster. Results on latest hardware is more impressive. There is some likelihood that Intel will continue to focus on this area (vectorized ops). Significant improvements in this area are much easier for them than in overall chip performance. AVX2 looks interesting, and the only thing holding us back, now that we have taken the hard initial steps, is that AVX2 hardware has just started to ship and we'll want to wait a year or so.
If you report an avx benchmark, please indicate the processor, as this gives useful perspective. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
