    What is AVX 1.1 ???

    yurtesen

      Hi,

       

      I see on wikipedia that piledriver based cores support AVX 1.1, but I couldnt find any information about what is included with AVX 1.1. Is this a mistake at wikipedia or what?

       

      Thanks,

      Evren

          Since there is no AVX 1.1 flag in CPUID, I think we can assume that AVX 1.1 = AVX1 + FMA3 + F16C + BMI1 (probably, but not likely), because the Bulldozer core has just AVX1, and the Piledriver core has all of them. In other words, it's a marketing BS, so if you don't see something in CPUID specs, then it doesn't exist.
