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
