    Is HD 5870 genuine 64 bit?

    viscocoa

      Does the ALU of HD 5870 support native 64 bit calculations? Does the following instructions use the same cycles?

       

      long int x, y, z;

      z = x + y;

       

      int a, b, c;

      c = a + b;

       

      Thank you in advance!
