I am interested in getting an idea of how much of a speedup I can expect when I move from my olde

HD 7700 to an R290X.  I currently have a 2GB PCI 3.0 HD 7700 running on windows 7, and my kernel

takes about 250 ms to run.  This is an image compression kernel, so there is a lot of memory traffic between

global and local memory.  Is it reasonable to expect a 10X increase in performance when moving to R290X ?


I realize it is quite hard to tell without running the durn thang.


And, by the way,  any progress on the board farm that was being discussed earlier ?
