    Fury random memory performance defect!

    smartbitcoin

      Based on the amd sdk app3.0 ,  the global memory benchmark program from amd:

       

      my test results shows:

       

      fury 's  float4 random performace is

      225.512 Gbps

      225/512 = 44% of the peak bandwidth.

       

      mean while , the  280x 's float4 random formance is

      192.248 Gbps.

      192/288 = 66% of the peak bandwidth.

       

      Does this a driver bug or the 1st generation HBM defect?

       

      the opencl drvier is 15.30.1025 , the latest one on ubuntu 14.04.
