    Fury X bus interface showing x8 1.1 ?

    jpham

      I'm running into performance issue (non game) so my vendor ask me if I can run GPU-Z

      showing the Fury X

       

      what we notice is that the Fury X Bus interface showing PCI-E 3.0x16@x8 1.1

      I use multiple GPU cards, the other card is AMD R9 295x2 and that card show PCI-E 3.0x16@x8 3.0

       

      what is the different  @x8 3.0 and @x8 1.1

       

      My vendor said the 1.1 is slower

      ==================

      system I7 with 32G of ram

      windows 7 64bit ultimate

      AMD R9 295x2 top most slot

      AMD R9 Fury x next top most slot

       

       

       

      Also does open CL handles multiple R9 card correctly ?

       

      thanks
